All About the Timing. The Fiat Abarth1600 Bialbero GT Coupe Italdesign

In its first decade and a half, Abarth entered into collaborations with Bertone only infrequently – just six projects: Biposto 1500 Coupe (’52), 750 Coupe (’56), Spider (’56), the Record Enduro cars (’56), 1000 GT Coupe (’58) and OTR 1000 Coupe (’65).  Meanwhile, Giorgetto Giugiaro added to his design activity at Fiat by also working at a desk at Carrozzeria Bertone’s Grugliasco offices.  His early projects there included such notable cars as: Alfa Romeo 2000 (’60), Gordon Keeble GT (’60), Ferrari 250 GT SWB Speciale (‘60), Alfa Romeo 2600 Sprint (’62) and Alfa Romeo Giulia Sprint GT (‘63).  In ’68, together with Aldo Mantovani, he established Studi Italiani Realizzazione Prototipi S.p.A. at Moncalieri.  The company advertised itself as Ital Design and its name was formally changed to Italdesign in ’87.  The first Ital Design project was the Alfa Romeo 1750 Berlinetta, soon followed by the Bizzarrini Manta.  In February ’69 Giugiaro’s first Abarth was presented – the 1600 Bialbero GT Coupe Italdesign.

The coupe was Abarth project 167, assigned model code 104G.  Factory records show the prototype as completed in February ’69, with a public debut at the Turin Motor Show on 29th October of that year.  Based on the ’66, type 137/C 1600 OT Sport Coupe, it was constructed on a sheet metal, box-type chassis.  The body, commissioned from Ital Design, was drawn by Giugiaro at the same time as he was creating the striking Alfa Romeo 33-based concept car, the Iguana.

The car utilised the Lampredi 1.6 Fiat twin cam engine which featured in such models as the Fiat 124 and 132, Lancia Beta and several Seats, with outputs in the range 87-98 bhp.  It entered the Corso Marche inventory as type #235 in ’62 when it was used to power the Fiat Abarth 1600 Coupe 2+2 Ellena, tuned to 98 bhp@6000 rpm.  An Abarth version, designated 235-C/A, generating 145 bhp, was developed for the 1600 Bialbero GT Coupe Italdesign.  Coupled with a vehicle weight of 674 Kg, the car’s top speed was projected as 150 mph, while a 0-62 mph time of 5.6 seconds was quoted.

Much as the Abarth products of the late Fifties/Sixties with Grand Touring designation had proven highly successful in GT category racing, their extreme compactness and (mostly) small capacity engines rendered them less than ideal for the long distance/high speed-in comfort role which came to define a ‘GT’ as the Seventies came into view.  Thus, the 1600 Bialbero GT Coupe Italdesign was intended to be the first of a new line of Abarths, with more spacious interiors and a generous measure of power derived from engines significantly bigger than the familiar ‘around one litre’ mark.  Typical Carlo Abarth, devoting much of his thinking to consideration of the future, anticipating customer preference trends, prepared to revise basic product formats and specifications.  Yet at the same time he was increasingly having to apply his mind to the existential issue of his company’s financial viability.

The late Sixties were not kind to the Abarth marque and Carlo himself.  Problems seemingly especially formulated to target Abarth, piled up in ’67.  Firstly, it became notable that the Touring Car racing class scene was changing quite radically, with changing rules, and a reduction in the number of younger drivers entering competition as escalating costs proved a significant deterrent.  Meanwhile, within the confines of the Corso Marche factory, the slow progress on the Formula One programme was stacking up costs as well as lowering morale.  Out on the streets, the national new car market was expanding, yet Abarth’s sales were down – to just 369 cars, only 54% of the total for ’66.  ’68 saw no reason for optimism.  There were homologation issues, disputes which resulted in withdrawal from both the Targa Florio and the Monza 1000 Km, still no external sign of the Formula One car and general economic unease as result of the Europe-wide ‘student unrest.’  And, perhaps most significantly, a revision of Fiat’s fundamental industry posture, which was evidenced by the acquisition of Autobianchi, Ferrari and Lancia.

It was thus a stressed Abarth that embarked on another new racing season/production year in ’69, yet it still did so on a wide and varied competitive front.  Indeed, it is probable that, driven by his dogged determination, Carlo was trying to do too much in terms of racing participation with very limited resources.  That had perhaps been a tendency ever since the ’58 Fiat ‘win bonus’ agreement, understandable on the basis that the more Abarth cars ran in races, the more likely they were to achieve victories and thus bring in the money from Fiat.  And on that very point, ’69 delivered a crunch.  As another aspect of Fiat’s changing strategic disposition, it set up a new competition-customer support division, with an intention to focus on rally involvement, believing this would support road car marketing more effectively than concentration on circuit/hillclimb events.  Accordingly, Abarth was notified that the ’58 agreement would be cancelled.  With that prospect looming, it is not surprising that as the1600 Bialbero GT Coupe sat in the Turin Show hall in autumn ’69, behind the scenes it had not proven feasible to devise any plans for putting it into series production.

So, the prototype remained a ‘one and only.’  I’m bound to say that I think that a real disappointment.  Carlo had once again shown his shrewd market intuition in seeking a creation from the pen of Giugiaro, a designer by then well into his stride with a highly impressive back catalogue, but also with a readiness to further evolve his vision and innovative inclinations.  His particular facility with the Grand Touring class which had recently been demonstrated with the Iso Grifo (’65), Fiat Dino (’67) and the Alfa Iguana would clearly have made the 1600 a sensational limited production premium GT.  Some criticism has been levelled at the relatively bulky rear quarters/overhang, but this aspect of the car’s aesthetics could easily have been enhanced in production by the use of larger diameter road wheels.

Overall, the form is expressive of purposeful elegance, well in tune with the taste trends of the time.  While those trends led to several GT cars which possessed comparatively claustrophobic interiors, the generous greenhouse of the Abarth ensured it had nothing of that sort about its cabin.  Had Abarth been in better financial shape I believe this could have been a successful new product, appealing both to existing customers and those who had never previously considered buying a car built at Corso Marche. 

As mentioned above, the loss of Abarth’s per-victory bonus payments from Fiat amounted to a final straw.  Within 2 years, Fiat would own the marque – as of 31st July 1971, publicly announced on 15th October.  It has become a convention that the 1600 Bialbero GT Coupe Italdesign was the last Abarth model developed and launched whilst the company was still in Carlo’s ownership – though it should be noted that no fewer than 17 new versions of previously launched models made their debut between February ’69 and October ’71.
 
Though this is unsubstantiated, the car is believed to be currently in private ownership in Japan.  It is seen below on display in Satiago in ‘11.
