Abarth 850 TC and 1000 Berlina - Sixties Supremacy

The Nuova 500 was launched by Fiat in mid-’57.  That Abarth should want to produce its own version was not surprising.  Whatever else might be said about the 500, its 13 bhp hardly made for good drivability characteristics.  Abarth’s modifications, upping power near twofold to 20 bhp, transformed the 500’s performance, which, Fiat-badged, initially struggled in terms of customer acceptance.  Unfortunately, the Tipo 105 Abarth 500 also failed to sell in the numbers planned, primarily because that increase in horsepower had come at the expense of a significantly higher price tag – 18% greater than that attached to the Fiat.  Carlo Abarth was quick to respond to the situation, ordering that a bespoke, 26 bhp version be made and adopted into his Monza circuit-based World Records programme instituted in ’56.  In February ’58, the car achieved a record by covering 18,186 km at an average speed over 7 days of 108.5 kph.  Fiat was impressed!  So impressed that Carlo was able to gain agreement from Fiat that it would make a payment to Abarth for every motor sport victory recorded by a Fiat-based Abarth product.  This arrangement proved to be extremely helpful over many years, primarily in supporting the development of new products and race activity at Corso Marche.  It is important to understand that in making the offer, Fiat’s Commercial Director, Lorenzo Brinatti, was firm in that only a race win would trigger each payment - any other placing was not to be recognised  This condition had effects which were not all totally desirable, the most significant being that Abarth’s view of what sort or races and classes it should concentrate on was perhaps overly slanted towards those in which its car could be considered favourite for the victory.

Three years on from the Monza record achievement and related ‘win bonus’ establishment, Abarth presented the first of a line of 850/1000 models which would be the most adept at garnering the best possible level of income from the agreement.  These models were based on the Fiat 600, which had begun production in ’55.  By the time of the Abarth 850’s unveiling, a million 600s had been made.  So, a success, certainly, but also a product that was due an updating.  This Fiat delivered with an increased displacement (767 cc) engine, designated 600 D – good for 29 bhp.  Abarth’s re-interpretation of the design included an uprating of engine output to 52 bhp in a model named 850 TC (Turismo Competizione) reflecting an increased cubic capacity of 847 cc.  Complementary specification changes also included Girling brake discs for the front axle and an additional radiator located midships under the floor.  An example of a 850 TC made in the first year of production is shown below.  #1022733, was raced in period by Gianpiero Raffa.  As offered in recent times by Woow Motors (Switzerland) it was in race trim with partial roll-cage and running on Cromodora alloy wheels.

The 850 TC was priced at Lit. 850,000 and clearly marketed as a model to win incremental sales volume.  Equally, it was specified with race wins in mind and in its first year on track/hill courses it began to deliver in August at the Cesana-Sestriere hillclimb, and nine high profile event victories had been gained before the season’s end.  September’s 500 Km at the Nurburgring was especially rewarding, with Ernst Furtmayr winning the 850 class.  Moreover, 850 TCs finished 1-2-3 in class.  Thus the advertising department at Corso Marche was soon busy with celebratory ads in the specialist press publications, example below:


To capitalise on the success seen at the ‘Ring, Carlo called for a special version of the 850 TC to be developed and this was done at some speed, the launch of the Abarth 850 TC Nurburgring occurring in November ’61.  (Curiously, this model, with designation, Project 64, Sigla 114, is shown in factory records as having been introduced in January ’61, 9 months prior to the launch of the 850 TC itself!)  Whether or not the January event was organised with the assistance of a clairvoyant, the car added to the buoyancy of sales as a result of enthusiastic customer reception of its features including a boost in power to 55 bhp enabled by a modified camshaft, a five speed gearbox, and a price tag only Lit. 40,000 bigger than that of the 850 TC.

There was variation in the badging of the Nurburgring model.  On some extant examples, the lower right corner of the engine decklid carries a generic 850 TC chrome script – left, below.  However, on #1458387/3320, ‘ABARTH’ and ‘nurburgring’ are added – right, below:


Of course the engine deck lid badges were usually not readily seen because of the prevalent practice, (increasingly so as of ’62), of running with the lid propped open. This – in contemporary parlance – 'hack' was seen as a silver bullet, the aerodynamic ramifications being in terms of downforce (improving rear end stability) and enabling a higher top speed – some said as much as an additional 5 mph, all at the same time as helping preclude engine overheating and heat sink in the bay. 

The ‘Nurburgring’ was a success both on track and in dealer showrooms.  This was helped by very favourable advocacy in the press, Auto-Italiana for instance having this to say in ’63:  ‘The performance of this inspired Abarth is certainly superior to that of a car of almost double its cubic capacity.  We would say that its engine despite the power that permits excellent performance, is elastic to the point that there is good acceleration even at a medium speed of around 3,000 rpm.  This is another positive quality of the vehicle, which is really a sports car but still relatively economical.’  But Abarth was not inclined to rest on its laurels – the 850/1000 TC range was the subject of gradual improvement/performance uprating over several years.  Progressive homologation update appendices were effected with a number of supplementary items, registered especially for ‘67/’68.  The 1000 TC Berlina was Group 1 homologated in January ’63.  The ’67 updates saw the approval applied for the Group 2 Special Touring class.
 
Some confusion can arise because of the moniker ‘Corsa’ applied to some ‘Nurburgring’ 850 TCs.  The is because Abarth also released in ‘61 a model with the ‘Corsa’ designation, this being the first of a line powered by the bigger capacity (982 cc) Tipo 210 engine.  The 1000 TC Berlina Corsa (#114D) was rated at 60 bhp.  The Tipo 210, was at the same time utilised in the Monomille Scorpione GT coupe.  Other important changes were driveshafts with universal joints and the fitting of disc brakes to the rear as well as the front axle.  Shown below is a ’63 example, #1428998.  This 1000 TC Berlina Corsa was sold in recent times for €24,900 by Race Cars Direct:

In early ’64, the Series 2 1000 TC Berlina Corsa’s power was up to 76 bhp.  Of significance, the underfloor radiator was relocated to the nose and housed within a newly designed protective nacelle with the appearance of a very heavy duty bumper, conferring a distinctive/aggressive ‘look’ to the car’s front end. 

The ’64-effective additional homologation features defining a Corsa version vis-à-vis the Berlina, included engine uprating, (12.2:1 compression ratio and 36 mm Weber), to a maximum of 80 bhp, 5 speed gearbox, discs all round, revised suspension and larger front radiator.  By ’64, the Berlina Corsa’s engine output was given as 76 bhp and numerous other detail, race-purpose improvements led to the designation, ‘2nd Series.’  This was followed in February ’65 by an 80 bhp ‘3rd Series.’  In particular, this featured a revised coil-over front suspension, distancing the Abarth set-up further from that of the Fiat 600 with its transverse leaf spring.  Performance was enhanced by the adoption of the 5 speed Tipo 121 gearbox.  The radiator capacity was also increased, enabling deletion of the engine bay fan, (the car still retaining a rear radiator in addition to the nose mounted item).  During the ’65 season, some 1000 TCs were raced with the Radiale head version of the 200 series engine.  The 4th Series of the Berlina Corsa appeared in September ’66, powered by the 210-C engine delivering 85 bhp thanks to a 13:1 compression ratio and a higher maximum rpm of 7,600.  Both the coolant radiator and the oil cooler were of increased capacity  The frontal radiator housing was restyled to enhance aerodynamics and the car’s weight was trimmed a little – down to 583 Kg.  As a result, top speed was reported to be up to 121 mph.
 
Proof of the 1000 TC’s prowess came in the years ’65, ’66 and ’67 when it was the Division 1 European Touring Car Challenge-winning car for Ed Swart, Giancarlo Baghetti and Willi Kauhsen, respectively.

The introduction of the 4th Series 1000 TC was concurrent with that of the 1000 TCR.  The ‘R’ signified the Radiale head and indicated a car with 92 bhp, available at an even higher engine speed of 7,900 rpm.

In early production, the Radiale engine’s 92 bhp, enabled a 0-60 time of 7 seconds and a top speed of 122 mph.  The model was developed with a 2nd Series appearing in February ’68, a 3rd the following year and a fourth in January ’70.  The 2nd Series benefitted from an increase in engine output to 97 bhp, while the 3rd had 108 and the 4th, 112-115, (at 8,200 rpm).  The final iteration’s top speed was 124 mph.

There were new Appendix J regulations for the ’70 season and the 4th Series TCR was Group 2 compliant.  With near-complete freedom in regard to the cylinder head, the rules enabled a further increase in power since twin double choke Weber 45 DCOEs were allowed, as were another iteration of both the camshaft and manifold, together with a prominent exhaust system with long transverse final pipe section.  Rear windows and rear screen were re-specified in Plexiglass, while the front and rear wings/wheel arches were widened and a new fibreglass engine deck lid fitted.  (This latter item was subsequently ‘unhomologated’ on the grounds that it could become debris of a dangerous nature in the event of a rear impact).  After feedback from the works drivers, in which they complained about how the car was handling with its increased power output, the rear suspension was reconfigured, reverting to a tubular components/triangular format arrangement, not unlike Fiat’s original design for the 600.
 
The driver most associated with the era was Johann Abt.  He joined the Corso Marche factory team in ’67 and won 29 races.  The following year he was a winner at 17 events and was a contender in the German Hillclimb Championship.  After leaving in ’70, Abt continued to race the marque’s cars and is thought to have notched up over 300 victories in the course of his career.

With various rule revisions, (most significantly, the 1st Division capacity limit in the European Touring Car Championship was increased from 1 litre to 1300 cc), and competitor strength changes, Abarth’s focus in ’71 shifted to the European Hillclimb Championship – once again, a successful campaign.  Otherwise, ’71 is remembered for the demise of the Abarth factory’s motorsport operation and the marque’s absorption into Fiat.  There was some bravado beforehand however - in February, Carlo, accompanied by Arturo Merzario, presented the SE020, SE021 and SE022 Sport Spider prototypes at the Torino Aero Club’s airfield just across the Corso Marche.  Then, where in previous years, comparative test sessions had been held at Vallelunga or Monza, these were conducted later that month at the Paul Ricard circuit, Le Castellet, France.  The emphasis on this occasion was on the Prototypes and larger engined cars.  Once the racing season got underway, Abarth fans might have thought that ’71 was going to be ‘business as usual,’ as March’s Monza round of the Italian Touring Car Championship saw class wins for Edoardo Gunnella in a 850 TC and for Gino Ravinale driving a 1000 Berlina.  In the mountains too, Abarth drivers Giuseppe D’Ippolito (850 TC) and Luigi Ferragina (1000 Berlina) were best in class in European and Italian Hillclimb events.  By the end of the season, Edoardo Gatti (850 TC) had taken the European Hillclimb Championship, 850 class, and Maurizio Campanini (1000 Berlina), the 1 litre class.  However, even as encouraging results were being recorded, Fiat informed Carlo that he would be deprived of the very thing that had facilitated so much motorsport success – the ‘per-win’ bonus payments were to be stopped.  On top of the many other commercial/financial problems with which Abarth had been struggling, this was a final straw.  At the same time, however, Fiat offered to buy the Abarth business lock, stock and barrel.  Carlo really had no option but to accept, and Fiat confirmed the agreement at the end of August, though it was not announced to the public until 15th October ’71.  Meanwhile, the racing department had been moved to the premises of Enzo Osella’s Osella Squadra Corse.  Osella would run the SE021 and develop the SE027 Prototype Spiders through to ’74. 

Eventually, as the 850/1000 TC’s development period had come to a close in ’70, the year before Fiat’s acquisition of the marque, the 850 had gone from a Lit. 850,00, 52 bhp car to one with many updated features and a 55 bhp-rated engine.  The 1000 TC began life with 60 bhp, while its ultimate successor, the TCR, had near double that, at 115 bhp.  Meanwhile, the price had reached, Lit.3,710,000.  Given the ‘per win’ bonus which Fiat had agreed to pay Abarth back in ’58, both the 850 TC and 1000 TC models contributed significantly to income over and above the sales revenues they generated, with no fewer than 2,357 race/class wins during the period ’61-’71, (1,236 by 850s and 1,121 by 1000s).
 
All these many decades after Abarth’s golden era, interest in the marque is strong and widespread.  Highly instrumental in the classic Abarth ‘scene’ is the Berni Motori business based south east of Milan at Maleo - http://www.bernimotori.com/.  Tony Berni – who has very kindly helped me in researching aspects of the cars on several occasions – summarises the history and allure of the 850/1000 TCs with this publication: http://www.bernimotori.com/press/Fiat%20Abarth%201000%20Berlina%20Corsa.pdf

Eight on the way to Twelve – the Abarth V8 Engine

Much was positive for Abarth as 1965 dawned.  Especially so in terms of the marque’s racing exploits.  For three years in succession, Abarth had taken GT World Championship honours, in the 1 litre class in ’62, 1.3 in ’63 and ’64.  In addition to these top-flight achievements, Abarth victories in national, regional and club events were commonplace, providing the Corso Marche treasury with regular and substantial income stemming from the ‘57 agreement whereby Fiat made a payment to Abarth for each and every race win credited to one of its Fiat-based models.
 
But there was a downside to this apparently generous, sugar daddy arrangement – to maintain the competitiveness of Abarth’s numerous racing customers, across a wide spread of model types/variants, it was necessary to implement an ongoing programme of product development and resulting upgrades.  This was an expensive business – enough so to be prompting Carlo Abarth, Renzo Avidano and Carlo Scagliarini to consider a major strategical revision of Abarth & C’s operational style and commercial objectives.  Whilst this would need to include an upscaling of road car production there should be no implication that racing would become a just an incidental, low key aspect of Abarth’s activities.  Indeed, Carlo sought to optimise the commercial benefits accruing as a result of his company’s motor sport expertise.  But, whilst up to that point Abarth was associated mostly with the smaller engine capacity classes, for a higher profile and thus a more powerful halo effect to enhance the marketability of the road cars, there needed to be a new focus on ‘bigger’ racing models which could contend for victories in the most prestigious categories, such as the impending FIA Groups 4, 6 and 7 for prototypes/limited production sports cars.  This was the media coverage-attracting realm of the World Sportscar Championship and events at places like Le Mans, Nurburgring and Monza.  In addition, there was soon to be the Can-Am Challenge, providing a potentially lucrative channel to the U.S. automotive market.  Equally, there was much to be said for the commercial opportunities that could flow from participation with a Grand Prix car in the Formula One World Championship.
 
Any such undertaking would, however, require substantial immediate investment, particularly in terms of engineering innovation and effort.  Abarth would have to step beyond its comfort zone – the world of relatively simple, two and four cylinder in-line engines.  What had been achieved in working with such powerplants was not to be dismissed – after all, the 2 litre 4 cylinder Tipo 236 unit would be giving all of 270 bhp in ’71 as Abarth was absorbed into Fiat.  However, in aiming to run against a competitor such as Ferrari fielding cars with 3 litre engines, Corso Marche was going to have to be the birthplace of an 8 cylinder motor.  That established, it wasn’t difficult to conclude that this would be best configured as a 90° V8.  And, once you’d got comfortable with that as a notion, with somewhere like Le Mans in mind it was not so hard also to start contemplating the possibility of a 120° 12 cylinder of twice the capacity!
 
Understandably, there has been speculation as to why Abarth chose in ‘66 to launch its first V form engine with a capacity of no more than 2 litres.  According to Gianfranco Bossu - colleague of Luciano Fochi, Abarth’s engine designer - the original proposal was to create the engine as a means to compete with Ferrari in the European Hillclimb Championship.  This implies a lack of confidence in how much more power could be extracted from the 1946 cc 4 cylinder, 16 valve tipo 236B, then good for around 245 bhp.  But what about the competition? – as an example, the 2 litre Alfa Tipo 33 at that pointed boasted 260 bhp.  So Abarth should really be seeking to run with at least something in the 270/275 bhp range.  From the ’65-’67 perspective, 30 more bhp from the 4 cylinder was a very tall order.  To achieve such an increase, an 8 cylinder was essential, both to allow for future displacement growth and to ensure that individual components could be operated under less stress, thereby enhancing reliability/durability, characteristics so important in the longer distance World Sportscar Championship events.  For ’67, both Prototypes (limited to 3 litres) and Sportscars (limited to 5 litres) also featured an up-to 2 litre class.  The 2 litre capacity gave Abarth options in terms of event classes/categories.  Until competitiveness had been established, ‘class wins’ would be possible even if overall victory would not.
 
The all-alloy, four cam Tipo 239 engine was first presented publicly at the Turin Racing Car Show on 26th February ’67.  With bore/stroke dimensions of 78 cm x 52 cm, the cubic capacity was 1987 cc.  The launch specification included twin spark ignition and four twin choke Webers.  With an 11:1 compression ratio, this initial set-up was said to be good for 230 bhp at 9,000 rpm.

With thanks again to Gianfranco Bossu, we know that the initial bench testing yielded very disappointing results in terms of both power and torque.  Gianfranco recalls that there was an immediate decision not to embark on an improvement programme and the project was in effect abandoned, the engine never chassis-mounted for track testing.  At the time, the Tipo 236’s maximum output was reported as being 220-230 bhp.  It is reasonable to infer that with the given greater weight of the Tipo 239 engine and its power being no more than 230 bhp, a V8-engined version of the SE04/L* would have been no quicker than one powered by the 4 cylinder.  Logically then, a decision to enlarge the Tipo 239 to 3 litres while tackling 2 litre class racing with the Tipo 236 seems well justified.

*The SE04 chassis which had been developed from the previous year’s 1000 SP model.  Thus it had a tubular chassis with mid-located engine, a car configured according to Mario Colucci’s thinking rather than Carlo Abarth’s.  However, a superficially similar car with box section chassis members and outboard engine had been built for comparison purposes.  First seen in May ’66 was a 982 cc engine-powered barchetta, of which 50 were built during the next 18 months, enabling it to be homologated for Group 6.  The two versions were tested at Vallelunga in January ’67, at this stage powered by the 4 cylinder Tipo 236 engine.  Evaluation concluded that future development should be with the mid-engine/tubular chassis configuration, designated SE004/FB2.  Rapidly forthcoming from the programme was a longer wheelbase version, identified as SE004/L.
 
Fochi pitched to Carlo Abarth the notion of increasing the cubic capacity, redesigning the heads with 32 valves and offering the engine on commercial terms to private customers.  Abarth apparently dismissed this idea out of hand, but authorised an evolution project for ’67 whereby the capacity would be taken up to 2968 cc.  This was achieved by increasing the bore to 88 mm and the stroke to 61 mm.  The prototype engine was put on the bench on 23 September ‘67, delivering 312.3 bhp at 8000 rpm.  It was first installed in a SE004/L chassis but soon mounted into a development of that car, designated SE013.  In what was otherwise known simply as a 3000 Sport Spider, the 3 litre Tipo 245 V8 made its race debut, a few days after its press presentation, on 6th October ’68 at the Aspern Airport circuit in Austria.  Especially noteworthy was the high location of the coolant radiator – above the top of the roll-over bar – over the rear of the mid-mounted engine, a concept anticipating Gordon Murray’s experimental external cooling solutions with the Brabham BT46 the following decade.  The SE013 at this point had ‘nervous’ handling tendencies which were exacerbated by the heightened centre of gravity to which the radiator significantly contributed.  Despite this, works driver Peter Schetty put the car on pole and comfortably won the race from Arturo Merzario, who was running in Group 6 with a 2 litre Sport Spider.  At Innsbruck, Schetty recorded a second 3000 circuit victory on 20th October.

Despite the ‘first time out’ victory, there was ready recognition that the car would not be competitive at higher profile events because of its handling characteristics.  With an ambition to run at the 24 Hours of Le Mans in ’69, it was essential that it be made easier/less taxing and tiring to drive.  But early-year progress was limited, leading to a decision that although an entry had been made, a Tipo 245-powered car would not be sent to Le Mans.  Instead, effort was invested in the evolution of the SE013 into the SE016, first shown on 2nd September ‘69.  Obvious at first sight was relocation of the radiator to within the body and the addition of tabs on the front/lower ‘corner’ of the front wings, both measures deemed important in seeking better overall balance and to militate against the car’s propensity to generate front end lift.  Another change expected to deliver better handling was to 15” wheels, (from 13”).  However, at this point, and for an extended period, such components were impossible to obtain from the usual suppliers because of widespread workers’ union-led strikes.  Driven by Johannes Ortner, the car was nevertheless competitive, (3rd when the race was prematurely stopped), at the 500 km of Imola, run later in the month.

In ’70, there were notable hillclimb victories for 3000 Sport Prototypes at Barisart (Belgium), Avignon (France) and Bergamo (Italy).  In late October, Abarth presented an upgraded version of the ‘3000 Sport Prototype,’ (SE020), at the Turin Motor Show.  Most notable revisions included a shorter wheelbase, more forward-located cockpit, extreme rear-mounted oil coolers and twin side placed coolant radiators.  The engine was upgraded – taking power up to 365 bhp – with the installation of fuel injection (Lucas) and capacitive discharge ignition (Dinoplex).  Despite these improvements, there was not a lot of confidence at Corso Marche.  Morale had been affected by a reduction in Abarth’s profitability and the disruptions attributable to Italy’s industrial relations strife experienced over the preceding three years.  Overlaying these fundamental concerns, was an internal recognition that the SE020 would struggle for competitiveness against the main Group 6, 3 litre class rival machines.  Though the Abarth V8’s power output was not greatly lacking in comparison with that of Porsche’s flat 8, (908/2), it was over 30 bhp down on the Alfa T33/3’s V8, and almost 100 bhp less than what the Ferrari flat 12 (312 PB) could muster.  A solution would be to resurrect Fochi’s 32 valve heads proposal, but with corporate financial robustness being as reduced as it was, that was a project which would again be deferred.

However, there was a niche which could be successfully exploited.  With a consistent record of good results in the category, there was a belief at Corso Marche that a bespoke version of the 3000 Sport could be a Group 5 contender for the European Hillclimb Championship.  Thus, the SE022 was unveiled in February ’71 at Campo Volo.  Designated a Monotipo, the SE022 was functionally similar to the SE020, but featured a substantial, enveloping-style windscreen frame/glass and carried a spare wheel for regulations-compliance.  ’71 saw nineteen 3000 Sport Prototype high profile hillclimb victories at Bellvue (Belgium), Draguignan (France), Liege (Belgium), Presberg (Germany), Villach (Austria), Gap (France), Jura (France), Abreschviller (France), Autun (France), Consenza (Italy), Berchtesgaden (Germany), Brescia (Italy), Avignon (France), Berwinne (Belgium), Clouneaux (France), Vuillifans (France), Trento (Italy), Sestriere (Italy) (2 classes).

Fig.05 SE022 driven by Johannes Ortner at Sestriere, July '71

Despite a visually appealing presentation of the three new Sport Prototypes and Carlo’s confident bearing at Campo Volo that February day in ’71, as an event this was a swansong.  On top of all the problems associated with the commerciality of the road car business and shortage of capital, a lack of confidence had been growing in Abarth’s motor sport customer community.  To ensure that such customers should not feel they were getting second best to the works team, Abarth created a division which could be seen as separate, self-sufficient and having 100% customer-focus.  He appointed Enzo Osella as its head, confident of the man’s expertise, abilities and alignment with his own principles.  At the same time he conducted a difficult negotiation for the sale of his company to Fiat, the confirmation of this being made in mid-October.  Fiat in effect endorsed the semi-external racing arm by delegating responsibility for the Abarth marque’s participation in the European Championship (for prototypes) to Osella for the ’72 season.  However, this did not involve utilisation of the V8 engine, and the cars became known as Abarth-Osellas.  But if that sounds like a downbeat development from a Corso Marche viewpoint, the upside was that with the Tipo 236 engine generating 270 bhp on Lucas fuel injection and a more reliable Hewland gearbox replacing the Abarth Tipo 139 unit, the Abarth-Osella SE021 was the championship-winning car of ’72.

l'Alfa Vince!

When I was visiting the Alfa Romeo headquarters at Arese in the early eighties, meetings were often disrupted by the noise and general disruption caused by workforce demonstrations which spilled out of the factory premises and into the office complex.  At that time, the place was a hotbed of political strife.  Often, I found myself lamenting the fact that considerable energy could be found for such activities, while apathy and a lack of dedication underlay so much of the poor quality that characterised the products these same people were helping stagger along the production lines.  But this was nothing new – Alfa Romeo had long been ‘state owned’ and able to function aloof from the commercial/economic principles that ensure that most companies manage their employees such that good order is maintained and a profitable operation enabled.

In the wake of WWI, Italy could not escape the Europe-wide economic crisis that saw crippling currency devaluations and raging inflation.  Things came to a head for Alfa Romeo in 1921 when its majority shareholder, Banco Nazionale di Sconto, collapsed.  It was however saved by absorption into a state institution, ‘IRI,’ which had been created by the Italian government.  Under this ‘ownership’ Alfa Romeo prospered through the twenties, thirties and forties, achieving success both in commercial car-building and motor sport terms .  However, in 1948, a new – though still basically state-governed – regime was introduced, leaving the company under direction from an organisation named Finmeccanica.  Resentment by the Alfa Romeo management of this arrangement ebbed and flowed over time, the main point of contention being Finmeccanica’s ability to interfere with production and the models programme strategies.  Almost as unwelcome was intrusion into the selection/appointment of senior leadership personnel.  Notwithstanding this latter point, the appointment of Giuseppe Luraghi as Alfa Romeo’s CEO in December 1960 was positive in that he championed the development of the Giulia models and the return to motor sport participation, including the establishment of Autodelta.  Also, he oversaw the move from Portello to Arese and the planning for the Alfasud project.  But within Finmeccanica and the government’s Economic Planning function, an arch economically conservative/anti-motor sport culture was maintained.  Consequently, as the seventies got underway, Luraghi was put under considerable pressure.  He was urged to abandon a plan to upgrade the Arese factory, to stop spending on motor sport and to abolish Autodelta.  The political climate featured a strong hard left element whereby the northern industrial area was represented as being a centre of capitalist greed which prospered at the expense of other regions – especially the South.  To address this, a plan was promoted to move a large proportion of vehicle production from Arese to a new site in Avellino, not so far from the new Alfasud plant at Pomigliano d'Arco.  All of this left Carlo Chiti, Autodelta itself, and the 33 programme in a notably insecure situation.
 
However, on-track, things were to prove a little more favourable for the team. The 12 cylinder 33 would start the 1974 World Championship quest with a 1-2-3 at Monza, though the rest of the season would be dominated by Matra.  Autodelta responded early on by deciding to dedicate most of the season to development of the car for an all-out championship onslaught in 1975, all the more attractive since there would be little Group 5 competition, (Matra having withdrawn), and  Porsche being focused on the GT category.

Late 1971 had seen the introduction of the T-33/TT/3.  The TT designation stemmed from the chassis being constructed as a ‘'Telaio Tubolare,’ a development away from the monocoque format T-33/3 which had begun testing in winter 1968-69.  In parallel, Chiti designed and began the building of a new 3 litre 180° V12, intended for both sportscar and Formula 1 use.  To carry this engine, a tubular chassis based on the T-33/TT/3’s was built, and the resulting car began testing as 1973 dawned.  It should have been sooner, but various delays were experienced, much of the trouble being attributable to the political milieu and Luraghi’s and Autodelta’s consequent uncertain situation.

‘Uncertainty’ soon gave way to deterioration.  Chiti had enjoyed considerable autonomy in Luraghi’s regime.  He believed that a free rein was essential to him if he was to design/develop engines and chassis which he considered were beyond the understanding of administrators, finance people and even the production car engineers.  But as the Spring arrived and testing opportunities arose, Chiti sensed that his Luraghi-bestowed ‘protection’ was diminishing, while the negative communications originating from Finmeccanica demanding reduced costs/better results grew in frequency and intensity.  Nevertheless, when Chiti was able to stand trackside and just concentrate on how the new car was going, he could feel more sanguine.  Rolf Stommelen was able in March to break the track record at Paul Ricard and the following month the same feat was achieved at Monza in practice for the 1000 kms.  Unaccountably – though ‘officially’ ascribed to problems with parts suppliers – no TT/12s were run in the race.  Eventually, the new car’s race debut occurred at the Targa Florio, the historic race in its final full bloodied iteration.  With Stommelen and de Adamich aboard, the TT/12 was satisfyingly fast, taking a clear lead, and looking certain to be a winner at its first attempt, until . . . de Adamich was hit by a Lancia Fulvia and suffered retirement-enforcing suspension damage.

Despite the signs that the TT/12 could be a really successful car, it was at this point that further pressure was exerted on Luraghi not only in regard to the main production organisation but also in the form of a challenge to the continuance of works motor sport involvement.  This situation seemed to affect the programme of race entries for the remainder of the season – just a single car at Zeltweg and non-entry for Watkins Glen and Kyalami.  But behind the scenes, engine development involving the cylinder heads enabled a useful power increase, proven by on-track performance in early winter testing at Vallelunga in the hands of newly-recruited driver Arturo Merzario.
 
By January 1974, Luraghi had finally had enough and he resigned.  The question of who should replace him as CEO immediately became a matter more conditioned by political bias than by the leadership, technical and commercial qualifications of the candidates.  With disagreement between the Christian Democrat and the Socialist factions unresolved, this important decision was fudged, a temporary incumbent being appointed.  This was Ermanno Guani, considered by many to be simply a puppet under the direction of IRI/Finmeccanica.  (Under Guani, a new Managing Director, Adolfo Bardini was appointed).  But at least there was no sudden termination of the racing programme or severe sanctions applied to Autodelta’s budgets/headcount.  Accordingly, testing for the new season began in February.  At this point there was some optimism resulting from Ferrari’s withdrawal, leaving Matra as the only serious opposition to Alfa Romeo’s quest for a World Championship.  After seeing some encouraging pace from Merzario at Monza, Autodelta sent two TT/12s to France for the Le Mans test in March.  The cars topped the timesheets, with Merzario 4.5 seconds quicker that the third placed, fastest, of the Matra MS670Bs.  Things got even better at the Monza 1000 kms, where the TT/12s were 1-2-3, led home by the car driven by Merzario and Mario Andretti.  Chiti was quoted as saying, ‘This was the greatest victory of my career.’  He was all the more disappointed – and bewildered – by the instruction from Bardini that no cars be sent to the next Championship round, at Spa.  Though participation was allowed for the following race, at the Nurburgring, the Monza magic had somehow been misplaced and only a second place could be achieved, leaving Matra by now well ahead in terms of championship points.  But though a determined effort could perhaps have allowed Alfa Romeo to close the gap and vie for the Championship, its own management decreed the opposite stance by instructing Autodelta to withdraw the Le Mans entries.  Thus, with the French team maintaining good performances and points scores in the remaining races, Matra-Simca finished the season as the champion constructor for the second successive year.  It then promptly announced that it would not contest a 1975 campaign.  At Arese the management was of like mind.  Costs were the dominant consideration and few of the senior figures believed in the positive link between motor sport participation and incremental sales, let alone the intrinsic spiritual value of the activity for a marque renowned for its sporting history.

Except . . . that autumn Guani was displaced by Gaetano Cortesi, an IRI-favoured executive.  As he settled into the CEO role at Alfa Romeo over the winter, signals began to emerge from his office which suggested that at least in 1975 there would be a racing programme for Autodelta to run.  Early in the New Year this became more likely when an agreement was reached with Willi Kauhsen to become involved in running the cars.  Most importantly for Cortesi in supporting his efforts to promote a less costs-obsessed culture in Arese, the German would bring with him a sizeable sponsorship budget which he had secured through associations formed in his previous role as a high profile works driver and entrant of factory-supported Porsches.  His expertise and experience went beyond endurance racing with his involvement in the 917 Can-Am and Interserie campaigns.

On paper the Championship prospects for Alfa Romeo in early 1975 were better than they had been for several years.  With Matra and Ferrari out of the way, the competition was relatively less intimidating.  Alpine Renault and Ligier both intended to run, but with cars less capable than the well-developed 12 cylinder MS670s of the compatriot Matra marque.  True, Porsche also had an updated, turbocharged 908 ready for action, but the 908/3 had performed poorly in 1974 and the new 2142 cc engine did not confer on the car a top speed capability equal to that enjoyed by the TT/12 and Alpine A442.  On the other hand, a substantial development programme enabled Autodelta to improve the TT/12’s chassis – especially the brakes and by the accommodation of wider tyres. And, making use of the Kauhsen sponsorship, the driver team was consolidated, with contracts for Merzario and Derek Bell; further agreements for some events were also made with Jacky Ickx, Jacques Laffite, Jochen Mass,  Mario Andretti, Henri Pescarolo and Nino Vaccarella.  The cars began the campaign with a red livery dominated by the team name initials in a white, huge size font, WKRT, on the front and on the rear wing. 

The promise was looking likely to be fulfilled when Merzario took pole position at the opening Championship round at Mugello.  However, brake problems delayed the car and allowed an Alpine victory, the Alfas finishing 2nd and 3rd.  Although that in itself was not a bad outcome, the post race atmosphere was clouded as a result of Merzario and Kauhsen not getting on.  Indeed, Willi’s involvement at this point was not especially positive since Chiti too harboured some resentment, feeling his ultimate authority was being challenged by the German.  Much of the problem stemmed from Kauhsen’s view that Merzario was ‘trouble’ and would not be in the team if he had his way.  But, when the next race – at Dijon – resulted in a morale-boosting Alfa win thanks to a very strong performance by Arturo, harmony began to set in. 

But, as confidence that this would be the Championship year grew at Autodelta, a new competitor emerged – the Gulf GR7 – and immediately proved itself by recording the fastest time in testing for the next round at Monza.  In the race itself, Merzario put in another robust performance, defeating the 908/3 pairing of Reinhold Jost/Mario Casoni and Larrousse/Jabouille’s Alpine; the Mass/Schenken Gulf suffered transmission problems and was classified in a lowly 20th place.  At Spa, the TT/12s were 1st and 2nd, driven by Bell/Pescorolo and Merzario/Ickx, respectively.  Another 1-2 followed at the Coppa Florio, Enna, Merzario/Mass being first across the line this time. The Gelo Racing Team-entered Mirage came back into play at the Nurburgring, running not far behind, but Merzario/Laffite still managed to take the victory from Howden Ganley/Schenken with a margin of 40 seconds.  It was Bell/Pescorolo’s turn to win at Zeltweg, with Merzario/Vittorio Brambilla second.  The season concluded at Watkins Glen with a repeat win for Bell/Pescorolo, Merzario/Andretti in second. 

The success that 1975 proved to be stemmed from several factors.  The involvement of Kauhsen was certainly important, though the value of his sponsorship was more in terms of its existence providing a means of countering the economic hawks within IRI and Alfa Romeo, it being implied that much of the spending burden had been transferred out of house.  Perhaps there were some clever presentations of figures by the pro-racing/Autodelta players since, in reality the WKRT contribution amounted to only 35% of the World Championship budget.  Any illusory enhanced portrayal of the arrangement would no doubt have been supported and facilitated by Gaetano Cortesi.  Indeed, the new Alfa Romeo boss’s favourable disposition did much to ensure that Autodelta, Chiti in particular, enjoyed a period of reduced top-echelon management pressure, enabling it to function better in engineering terms as a developer of the car.  And the developments introduced during the season were largely successful.  As mentioned above, chassis/brakes improvements enhanced the TT/12’s competitiveness, as did an upping of engine power output to 500 bhp, (a 6% increase over the original rating).  Numerous detail changes were made to the bodywork of the T-33/TT/12, helping both airflows to the engine and brakes and the car’s aerodynamic efficiency both in drag reduction and downforce generating terms.  And, although he didn’t quite make a significant mark in Formula One, Arturo Merzario’s contribution to the Alfa Romeo Championship win is perhaps underrated.  Highly respected by hard task master, Carlo Abarth, ‘Little Art’ gained a lot of specific expertise at the beginning of his career in a test driver role at Corso Marche.  At Autodelta he remained always ready to put in test mileage and was able to give good, constructive feedback which was a positively enabling factor in the development process.  This attribute was probably as important for the success of the campaign as his four race victories.  Commercial developments also were important in sustaining the Championship campaign.  In May the cars appeared at Spa with a new livery for the Campari drinks maker, reflecting a useful sponsorship addition to the racing budget.  The following month, appropriately at the Nurburgring, the name of the sausage manufacturer, Redlefsen, was writ large on the 33s.

One week after the Watkins Glen victory, the now-non Championship Targa Florio, run two months later than had been the custom when the event was in its pomp, provided a further and concluding celebratory victory for the T-33/TT/12.  Merzario was paired with Targa specialist-supreme, Nino Vaccarella, and they had no difficulty in winning the race by the large margin of 19 minutes from a Chevron B26.

As the summer gave way to autumn, the focus passed from the 33 to the utilisation of the 12 cylinder engine in a new partnership with Motor Racing Developments, (Bernie Ecclestone’s Brabham Formula One team).  The BT45 chassis designed by MRD’s Gordon Murray was ready for track testing by Carlos Reutemann in mid-October.  Thus, Alfa Romeo became involved in Grand Prix racing again for the first time since the (second) Championship-winning year of 1951.  This would give rise to a further two new engines – a V12 and a turbocharged V8 – before ending in 1988, with little success achieved, when the V8 was dropped after 3 seasons’ use by the Osella team.

Without any clear conviction, Alfa Romeo did decide to develop a version of the 33 for the newly-redefined Group 6 introduced in 1976.  On paper this appeared to be specified in stark contradiction to the principles that had made the TT/12 so dominant in 1975: the tubular chassis was to be replaced with a monocoque and the 3.0 litre capacity/natural aspiration, (which helped ensure good reliability) of the engine was due to be replaced by a 2140 cc version with twin turbocharged induction.  The race debut of the car, originally referred to as 33TS12, subsequently, SC12, was delayed, in a manner precursory to the saga of the Formula 1 890T engine in 1982-3, by difficulties over the sourcing of the turbocharger units.  Eventually, some appearances were made, and there were interludes of encouraging pace, but 1976 was really a blank year for Alfa Romeo in terms of sports cars racing.  1977 was certainly different, even if the scale of the success attained was limited.  Using the normally aspirated SC12, the team won all 8 rounds of The World Sportscar Championship.  This, however, was open only to Group 6 cars and was not the FIA’s premier competition for such machinery – that distinction being reserved for The World Championship for Makes, won in dominant fashion by Porsche with its phenomenal 936 model.  The turbocharged car ran in the hands of Merzario at the end of the season in Austria, but was outpaced there by Brambilla’s atmo SC12.  Perhaps just to ensure that the turbo SC12 would never emulate the glories racked up by the 3.0 version, the FIA announced that Group 6 was to be abolished as from 1978.

So, Alfa Romeo’s foremost motor sport role in the New Year was as the ongoing engine supplier to the Brabham team.  But this arrangement was about to change too because Brabham needed a narrower unit to enable the construction of a new chassis which could exploit the fast-developing principles of ground effects.  In response, Chiti had a 60° V12 design under way in October.  Behind the scenes, Chiti had also been at work for some time on the design of a chassis to be powered initially by his 180° V12 cylinder engine and with which to race in Formula 1 as an Alfa Romeo.  The car was ready to begin testing by mid-year and there was hope that it could make its race debut at Monza in September.  That proved to be over ambitious, and it was not until May 1979 that it was seen at a Grand Prix.  Regrettably, what happened over the following six seasons was never anywhere near as uplifting as what had been achieved with the T-33/TT/12.

The Lingotto Biscione and the Parella Scorpione

 



In considering Abarth Corse’s final racing season it’s necessary first to go back four years and understand the unfavourable market conditions that had begun to threaten the Corso Marche factory’s very survival.  1967 saw a big drop in demand for – and, thus, production of - Abarth cars.  This was not due to any shortcomings of the products themselves but resulted from the sales inroads made by other manufacturers who had introduced new sporting variants to supplement their previously more mundane model ranges. 

Abarth’s strategic response was well-considered and logical.  Racing activity would be stepped up.  For Abarth, even more competitive achievements such as the recent run of World Championships would support marketing messages stressing the products’ actual/race-proven sporting qualities – demonstrating that they were not just models with slightly more performance and a set of stripes.  Additionally, and as a very valuable short-term benefit, more racing leading to more victories would mean more win-bonus payments from Fiat, since the 1958 contractual agreement on this was still in force.  It has however been suggested that the agreement may, paradoxically, have been partly responsible for the Marque’s eventual demise.  The argument posited is that Abarth over-focused on the 595/695 models as these generally were the most likely to win events.  As a result, development of other model lines, such as the GTs, was comparatively neglected despite these being products that especially embellished the brand image/reputation and which tended to carry significantly better profit margins.


The 1300 OT (above) had been introduced in 1965, and once homologated for Group 4, became a convincing front-runner.  Victories and podium placings were soon forthcoming in the DARM, (German Automobile Circuit Championship).  Then, in the International Sports Car Championship, as early as the April round (3) at Monza, the OT driven by Anton Fischhaber/Ernst Furtmayr/Giancarlo Baghetti won the Sport 1.3 class.  Two months later, at the Nurburgring 1000 kms, Kurt Ahrens Jr./Johannes Ortner/Wolf-Dieter Mantzel/Furtmayr took the same honour.

At Mugello, a 1300 OT took the class win with Luigi Taramazzo and Giulio Bona driving.  Alfio Gambero’s 1300 OT was 3rd overall and class winner in the Coppa Citta di Enna.  Next it was Helmut Krause’s turn to take the 1.3 class victory at the Hockenheim Grand Prix.

Overall winner of the Nurburgring 500 kms was Ernst Furtmayr, and Johannes Ortner rounded off a terrific set of class wins for the 1300 OT with 1st place at Zeltweg.

Thus, 1966 saw another Abarth series victory – taking the title in the International Sports Car Championship, Division 1, 1300 cc.  The new 1300 OT had quickly proven its capability and there had been good individual race, class-winning, contributions too from the 1000 SP, the 1000 Bialbero, the 1000 S and the 1000 OT. 

In 1967, the 1300 OT maintained its status as the Number 1 car in the Sport 1.3 class, with wins at the Targa Florio, Le Mans, Hockenheim (outright winning car), Mugello, Enna, Zeltweg, Ollon-Villars and the Nurburgring 500.  There were some good performances in the Prototype class too for the 1000 SP.  Yet another championship year for Abarth Corse.

As said above, 1968 was the season in which Abarth was seeking more wins, especially with those Fiat bonus payments in mind.  But the outcome proved to be largely one of disappointment.  Bad enough that this became the first season since 1962 that Abarth could not boast of a World Championship.  Individual race results too were uninspiring.  A Fiat Abarth 1000 S took the Sport 1.0 class at Monza, but the only other international grade victories were achieved at the Targa Florio.  The performance in Sicily was something of a compensation because Abarth cars won three of the nine classes contested – Sport 1.3 – Giovanni Rizzo/Stefano Alongi, Abarth Simca 1300 Bialbero; Prototype 1.0 – Francesco Patane/’Oras’, Abarth 1000 S; Sport 1.0 – Cesare di Belmonte/’Don Pedrito,’ Abarth 1000 OTS.

The policy of a more diversified models/more numerous entries approach referred to above became more evident as the 1969 season got underway.  At the Brands Hatch Six Hours, an SRT Holland-entered Abarth 2000 S ran in the hands of Gijs van Lennep/Toine Hezemans.  Launched in 1967, the 2000 S was a development of the 1000 SP and known internally as model SE04.  The mechanical configuration and dimensions were revised repeatedly as Abarth sought the optimum template for a successful customer race car model.  Results in 1967/8 were modest, but 1969, (and 1970), would see a good number of class wins/podiums.  To allow for competitive participation in the Sport category (rather than Prototype), a homologation-required quantity of 25 units was built in 1968/9 of the further development, SE10, version.

However, whatever the success that these later developments would bring, the SRT car at Brands Hatch  showed that much work would be needed.  Qualifying only 21st, it was a non-finisher. 

At Monza, for the 1000 kms in April, three Abarth models were deployed – another outing for a 2000 S, two 1000 S models and three 1000 SPs.  Although three of the cars retired, there were class wins for Ugo Locatelli/Maurizio Zanetti, 1000 SP (Prototype 1.0), and "White"/Umberto Grano, 1000 S (Sport 1.0).

The Abarth contingent for the Targa Florio amounted to 9 cars of which two were class winners, and in the Sport 1.3 class Corso Marche products filled the first four places.  Leading the way was the 2000 S of Bitter/Kelleners, 8th overall and first in the Sport 5.0 class.  Winning the Sport 1.3 class was the 1000 S of Salvatore Calascibetta/Vincenzo Ferlito.

Also seen on the Madonie circuit in 1969 were three more 1000 SPs, a 1300 OT, a 1000 OT, a 1000 S, and an Abarth Simca 1300 Bialbero.

Le Mans was not an attractive event for teams running Abarth models in 1969, and the only runner of note was an Ecurie Fiat-Abarth France-entered 1000 SP for Locatelli/Zanetti, although this did not last long, retiring after nine laps with ignition failure. The car has however been preserved in beautiful condition, as seen below, at the 2022 Chantilly Arts & Elegance Richard Mille Concours:

1969 also saw the launch of an evolution of the OT 1300 /124 Scorpione.  This model, was based on the Fiat 850 chassis, but with a coupe body styled and built by Carrozzeria Francis Lombardi.  Lombardi marketed its own version as the 'Grand Prix,' and there was another variant branded as OTAS-Turin.  The Abarth had the superior specification in terms of engine performance and chassis details.  These were further enhanced in 1969 with a re-designation as the 'Scorpione SS.'  With notably good handling and power up to 88 bhp, the model had plenty of race potential.  However, with very few produced, coupled with growing uncertainty about Abarth's ongoing viability, especially its racing activities,  Scorpiones were little seen on the competition scene of the times.

1970 was to be the last full season in which Abarth Corse would be active.  Initially, there was plenty going on.  A definite highlight was the new SE018, a more compact, lighter Abarth 1000.  In this period there had been an ongoing internal contest between Carlo Abarth and Mario Colucci, his Chief Engineer/Designer, over how the cars should be configured.  Colucci was keen to execute the pure racing sports/prototypes as mid-engined machines, whereas Abarth favoured the rear-located solution which had brought him so much success over the previous twenty years.  By the turn of the new decade, he had prevailed and the SE018’s attributes included the progressive handling characteristics conferred by the rear mounting of the power unit.  However, the other new-for-1970 car, the 2000 SE019, could be delivered in either mid or rear-engined form!  Shown below is an example of the SE018, the rear location of the power unit being very evident from this angle.  This car is chassis #015, offered for sale by Bonhams in March 2015 with an estimate of £90-120,000; (withdrawn prior to the auction).

As recounted by Asmonzaracing, a SE019 of the mid-engine, (‘entrobordo’) type featured in a head-to-head battle with the outboard engine version – ‘fuoribordo ‘ – at Mugello in July 1970.  The race was won by Arturo Merzario driving a fuoribordo with Kinnunen second in an entrobordo.  Below, on the left, is a contemporary photograph of Merzario in the fuoribordo, (with Carlo Abarth directly behind the car), while to the right, an entrobordo is pictured at Imola in 2019:

There were nine Abarths entered for the Targa Florio.  Heading the contingent was a pair of factory-run 3000 SPs for Arturo Merzario/Johannes Ortner, and for Mario Casoni/Jonathan Williams.  The latter car was damaged in practice and unable to start the race, whilst the other managed only two laps before succumbing to gearbox failure. More positively, 2000 S SE10s were 1st and 2nd in the Sport 2.0 class, an SE04 1000 SP won the Prototype 1.0 class, and a Scuderia Pegaso 1300 OT took victory in the Sport 1.3 class.

In addition to The SE019s, the racing models launched by Abarth in 1970 were:
 
Fiat Abarth 1000 TC Radiale Berlina Corsa:  Responding to further revisions of the FIA’s definition of racing classes in the ‘Appendix J’ of its International Sporting Code, this version of the 1000 TC was specified to comply with the Group 2 rules.  This was for ‘special touring cars’ with a homologation requirement of at least 1,000 units/year.  The regulations were helpful in so much as they allowed Abarth to utilise the Radiale head.  (This featured combustion chambers of a form embodying two overlapping hemispheres.  This promoted more efficient mixture charging/combustion.  On the 1 litre engine, the Radiale head was good for a 27% power increase, to 108 bhp.)  It had been seen previously in 1966 for Group 5 classes allowed in England and France.  The widespread accommodation in 1970 of such a specification was a clear benefit to Abarth.  Ongoing development saw power further improved to 112 bhp, and, coupled with the low weight value of just 583 kgs, competitive performance was assured.  It was certainly good enough to secure the title for Abarth of Division 1 of the European Touring Car Championship, with class wins at five of the nine rounds.  Johann Abt was 2nd in the drivers table to Toine Hezemans, who, though earning his championship-winning points mainly by driving an Alfa Romeo 2000 GTAm in Division 3, also drove a 1000 TCR at the Zandvoort round.

Fiat Abarth 695 SS Assetto Corsa Series 3: Whilst the 1000 TCR represented a culmination of upgrading/improvement to the 600-based berlinas, the 695 SS Assetto Corsa Series 3 embodied the same summation for the variations on the 500 theme.  That Abarth at this point was every bit as concerned with marketing as with engineering, is indicated by the range of variants concurrently offered: 595, 595 Competizione and 695 SS Assetto Corsa.  It was also possible to have post-sale conversion to uprate the engine with a Radiale head.  However, the SS Assetto Corsa boasted at least 38 bhp on 520 kgs, so was a capable front runner.

By May 1970, the number of 695 SS cars to be seen on-track had become substantial.  At the Trieste-Opicina hillclimb, for example, six ran in the 700 class, with Cesare Garrone taking the win.  At Imola the class win went to Antonio Leone.  At this event there was some competition for the 695s, a BMW 700 CS running in the same class.  Otherwise, throughout the season, the Abarths had the 700 class almost completely to themselves. 

As said at the outset, the late Sixties had brought much pressure for Carlo Abarth, especially in terms of sales and the related existential issue of corporate solvency.  The latter concern was not helped by the more extreme aspects of Carlo’s search for the higher racing profile intended to secure increased sales revenues by enhancing the appeal of the normal production cars.  There were two such aspects and both not only drained funds but also distracted attention from customer-sales-related operations.  Firstly, there was the T140 Sports Prototype project initiated in 1966 and founded on the creation of a six litre V12 engine.  A chassis for this was built, and testing became intense during 1967.  However, quite abruptly, the FIA revised its definitions of the Group 5 and 6 categories relevant to the World Sports Car Championship.  Whilst the main thrust of the changes was to introduce a 3 litre engine capacity limit, provision was eventually made for 5 litre engines, but subject to a homologation requirement of 25 built examples.  Having invested much time and money in the project, Abarth had to face up to the reality of his situation, one in which he lacked the resources which permitted both Porsche and Ferrari to meet the homologation requirements and subsequently contest the World Championship with their 917 and 512 5 litre models in 1970-71. 

As if the T140 project was not enough to be going on with, a 3 litre Formula One car had also been under development.  Whilst not very much has been written about this, we do have an interesting account from Jonathan Williams in his autobiography, Shooting Star on a Prancing Horse.  Finding himself no longer wanted at Ferrari, Jonathan had a meeting with Carlo in late 1967/early 1968.  Jonathan was invited to be the driver of a ‘secret’ Abarth Grand Prix car.

I was given a tour of the factory and saw ‘my’ F1 car.  It was a Cooper style space frame with a 3 litre V8 engine.  This was when everyone was moving to monocoque chassis.  I knew right away that it wouldn’t be competitive, but I would never find out.  During the next few months, little if any work was done on the car, and it was eventually shelved and the project abandoned.
 
There are several accounts by people who interacted with Carlo which attest to his tendency towards arrogance and inflexibility.  To a degree, these sorts of trait would have been key to the character that enabled the man to have a singular sporting/engineering vision and the energy/resilience necessary to establish and grow a business in a competitive milieu.  Such a personality may have difficulty in evolving a changing operational outlook in response to a company’s developing size and scope of business.  In such circumstances, it is often the case that there is a natural successor with the mindset required.  And, perhaps as the ideal, this has often been realised by a son/daughter, likely aligned with the father’s core values, but able to contribute a new dynamic to their delivery.  In Carlo’s time, this would be the vocation for a son, but there was none.  It has been suggested that Carlo may have looked upon Peter Schetty as a surrogate for the role.  In his late twenties, Schetty’s prowess as a driver was backed up by a formal engineering training at university and a naturally confident manner stemming from his upbringing in a wealthy business-owning family.  Like Abarth, he was highly accomplished in carrying out vehicle testing, analysing results and planning developments.  But, ironically and unhappily for Carlo, Peter was perhaps too good – his reputation being sufficient to prompt Ferrari to headhunt him.  Thus, he left Abarth to work at Maranello, where in 1971 he took over the management of Scuderia Ferrari, securing the World Championship for Makes the following year in very convincing style.
 
As 1971 dawned for Carlo, his attention could not be exclusively focused on the new cars that would represent the Marque that season – he had also to find a means by which he would have the wherewithal to continue the enterprise through to 1972.  His options were however severely limited and, eventually, he would not be able to find an alternative to a sale, lock, stock and barrel, to Fiat.
 
Meanwhile, there were new cars to be launched which had the potential at least to bolster Carlo’s asking price as a result of renewed on-track success.  Whilst the ambition – perhaps disastrously overreaching – of the T140 had come to nothing, Abarth remained keen on seeking the prestige associated with running in the larger capacity prototype form of sports car racing.  Thus, two new 3000 Sport Prototipos were presented to the Press in February.  The 365 bhp 2968 cc V8 engine had by then been through five years of development, including enlargement from its original 1978 cc displacement.  For 1971 there was a circuit racing version – SE020 – and a hill climber, SE022.  Although there were some serious issues of potential competitiveness, at least at this point the question of engine location on both cars – and the 2.0 SE021 – had been resolved: mid-engined, as had become the general convention by then, as well as validating Ing Colucci’s philosophy.  These cars are sometimes referred to as Sports Spiders.  The SE021 is considered a significant model as it benefitted from the increased influence of Enzo Osella, (who had first worked for Abarth in the early Sixties), and Antonio Tomaini, both of whose status within the Abarth organisation had been revised and uprated.  Its success was confirmed when it took third place in the 1971 season’s European Championship.
 
A major issue for the SE020 was the Abarth V8’s power disadvantage against the competition.  At a very simple level, the relevant classes were restricted to 2 and 5 litres, so any 3 litre, however good, was bound to have a significant power deficit.  As to other 3 litre cars, the flat 12 in the Ferrari 312 PB delivered almost 100 more bhp.  The Alfa Romeo T33TT3’s V8 was capable of over 400 bhp, as was the Matra MS12 V12.  Even the less up-to-date Porsche 3 litre flat 8 was a little more powerful.  To make matters worse, even the relatively modest 365 bhp of the Abarth unit was more than the transmission had been designed for, and reliability thus came into question.
 
Abarth recognised that both performance and quality concerns were affecting customer confidence.  To overcome this, he decided to consolidate a specialist motorsport customer-support orientated division in the style of Alfa Romeo’s Autodelta.  Also responsible for running the factory cars on-track, Osella was publicly announced as the manager of this new operation, the Abarth Reparto Corse.
 
At Monza, in April’s 1000 kms, an SE10 2000 S driven by ‘Pal Joe’ and Romolo Becchetti won the 2 litre class, though there were only three other Sport 2.0 class cars contesting the race.

SE021 2000 SP of Arturo Merzario, Imola (European 2.0 Championship)

Seven Abarths started the Targa Florio, but only two were finishers.  However, these, both 1000 SPs, came in 1st and 2nd in the Prototype 1.0 class.

Also new for 1971 were: 

1300 Sport Spider.  This was in effect an SE021 with a 190 bhp version of the 1289 cc engine.  It maintained the Marque’s reputation for being able to dominate the 1300 class of the Italian national championship.

Autobianchi A-112 Abarth Berlina Series.1.  The Abarth version of the A-112 was in development soon after the standard car’s launch in 1969.  That development process straddled the sale of Abarth to Fiat and in several ways does not seem to be typical of the Marque.  It was, however, a significantly upgraded machine, with engine power 35% up on that of the standard car.  Eventually it would receive further modification, with consequent power increases, in the guise of a Fiat rally ‘special.’

Fiat Abarth Formula Italia.  This, again, was a project which though begun whilst Abarth was still independent, did not really emerge in public until after Carlo has completed the corporate sale.  The car – SE 025 - provided a ‘junior’ format allowing drivers to compete in identically-specified single seat, open wheel machines.  The series was crucial to the establishment of the careers of several Italian drivers who would make it to Formula 1, including Ricardo Patrese, Michele Albereto and Bruno Giacomelli.  The tubular chassis was the work of Abarth’s Ing. Colucci and it remained the Formula’s control chassis until 1979, when it was replaced with a Lancia Beta-based, transverse engined, semi-monocoque.

With Carlo preoccupied with negotiations with Fiat, it is perhaps not surprising that there was no Abarth representation at the rounds of the International Championship for Makes after the Targa Florio.  Those negotiations did not look likely to succeed for quite some time, Carlo Abarth seeking to be uncompromising despite the underlying weakness of his position.  However, his partner from the time of the company’s formation, Carlo Scagliarini, who enjoyed a good relationship with Fiat’s commercial director, intervened, and, through an intense period of discussion, was able to broker an agreement which was finalised in July.  Abarth’s third wife, Anneliese, has provided insight relative to the standing of the Reparto Corse in the negotiations:

Fiat had immediately declared that it was not interested in the Reparto Corse.  Carlo Arbarth then turned to Enzo Osella, before formalizing the sale to Fiat, so that he could take over all the equipment of the Reparto Corse, granting him payment in instalments as long as his name continued in racing.  In addition to the equipment and the cars, a dozen of the best mechanics went to Osella, (another 30 were hired by Fiat), Antonio Tomaini and, among the drivers, Arturo Merzario and Domenico Cedrati ‘Poker.’  The transfer of all the equipment of the Reparto Corse to Osella took place during the closure of August.  With the ex-Abarth material, Osella formed the ‘Osella 1972’ Scuderia. 

The sale of Abarth to Fiat was made public in October 1971.  As a result of Osella’s activities, there was the appearance of ongoing Abarth race car development, underpinned by an important measure to address the transmission reliability problems that had recently been experienced.  The situation was addressed by the simple expedient of substituting a Hewland ‘box for the Abarth unit.  With the adoption also of fuel injection and a resulting increase in power from the 2.0 engine, the SE021 in 1972 form was good enough to win the European Championship

For a while, Carlo remained involved on a consultancy basis, though it must have been difficult for him to accept a situation where he no longer had autocratic power and would have to defer to Fiat management as a generality.  Eventually he retired, leaving Turin and relocating to Vienna.  He died in 1979, just short of his 71st birthday.  Today the Abarth name enjoys a renewed currency as an overtly sporting brand of Fiat, and his personal achievements are very well celebrated by the Carlo Abarth Foundation.
