Small Scale Style from Scaglione

During the late 19^th and first half of the 20^th centuries, Neckarsulm Strickmaschinen Union – NSU – dabbled with automobile production, but was mainly known for its motorcycles.  However, a more concerted fresh new start with cars began in 1957 with a model type named Prinz.  A small saloon, the Prinz was powered by an air cooled, rear located 583 cc twin cylinder engine.  A distinctive feature of the NSU twin was its utilisation of a connecting rod driving the overhead camshaft from the crankshaft.  The system, known as ‘NSU Ultramax,’ clearly had reliability/durability advantages compared with the more usual chain, gear or belt drive, but would have added to costs somewhat significantly. (See here).

Despite the limitations of its size and small capacity powertrain, the Prinz was successful in terms of sales, with about 95,000 units made in the period ’57-’62.  Not quite a microcar – more a super-compact - it met the needs of a large, city-dwelling demographic seeking economic motoring.  Such owners had no need for full four seat capacity for lengthy journeys.  The ‘economy’ criterion was met by the Prinz being a car that cost all of £425 brand new.  But, as throughout the history of automobile manufacturing and marketing, modesty is never absolute and it wasn’t long before designers at Neckarsulm were doodling sporty body shapes over the basic Prinz platform.  After all, Volkswagen had not long ago put a sports coupe body jointly developed by Carrozzeria Ghia and Karmann GmbH onto the Beetle chassis, and the resulting car had proven an aesthetic and commercial success.  NSU turned to another fast-developing carrozzeria to explore a similar project.  This was Bertone, where Nuccio, son of the firm’s founder, was intent on modernising and expanding its operations, especially in terms of vehicle assembly in addition to body styling and construction.  And Bertone had been benefiting since ’52 by having the talented stylist, Franco Scaglione, in-house.  Scaglione was at the time riding a crest of success and acclaim through his recent work for Alfa Romeo, (the startling Berlinetta Aerodinamica Tecnica (BAT) concepts, the Giulietta Sprint and the Sprint Speciale), Abarth and Aston Martin.  Confident and adventurous, Scaglione drew a distinctively attractive fastback body which the NSU management found very much to its liking.  Little wonder as Scaglione had flattered the executives at Neckarsulm by presenting them with the opportunity to market a Prinz that had a similar look to the glamorous Maserati 350 GT Bertone which was on his drawing board around the same time.  The Sport Prinz was first presented at Frankfurt in ’58, with series manufacture and deliveries beginning in ’59.

According to most sources, Bertone built the first 250 Sport Prinz bodies in the Carrozzeria’s Grugliasco workshops near Turin. This operation was then transferred to the firm of Drautz, conveniently also located in Neckarsulm.

From the outset until ’62, the 583 cc engine with Bing carburettor was rated at 30 bhp DIN (or, claimed, 36 SAE), with torque at 42 Nm.  The car’s kerb weight was quoted as 530 Kg, allowing a top speed of over 80 mph, though the 0-60 mph acceleration time was over 20 seconds.  However, being nimble and handling well, the model was to be seen on race circuits in 1960 and with some success, for example at the Nurburgring in September, where Siegfried Mullers and Bernd Degner were GT600 class winners in the 500 Km. 

In ’61 two cars ran in the Monte Carlo Rally. Eugen Schaefer/Henri Benveniste’s #116, which finished 60^th, is seen below:

The second car, in the hands of Jose Behra/Jean Berges, was an excellent 8^th . 

During 1960/61/62, SCCA racing in the U.S, saw Sport Prinz participation from time to time, notably with Alfred Zantzinger at the wheel.  At the Sebring 12 Hours in ’61, Fred Fischhof and John Eisenhauer took the GT600 class honours.  Remarkably, in June ’63, six Sport Prinz entries were seen at the Nurburgring 6 Hours, a round of the European Touring Car Challenge.  Most successful was the Isar Racing Team car driven by Ernst Hamberger and Manfred Gieth to 1^st in the up-to-600 cc class – indeed, the model recorded a 1-2-3 finish at this arduous event.  The winning car is #8, centre, in the photograph below.

A few weeks later, Hans Braun won the same class at the ETCC round at Zandvoort.  In the Tour de France, Sport Prinz cars were 2^nd and 3^rd in class.  There was some Sport Prinz representation at the major hillclimb events at Rossfeld and Mont Ventoux in ’64, while Christian Chauvin was class winner at the ’65 running of the Coupes de Paris. 

The Sport Prinz was the subject of a road test report in the November ’60 issue of Motor Sport magazine.  Comments included: 

(The engine) . . . idles unevenly but once under way smooths out, although the noise is still very reminiscent of a two-stroke engine.  The gearbox operates in the rather disconnected way of so many rear-engined cars, and the synchromesh tends to obstruct gear selection, especially in first gear.  To obtain good downward gear changes it is advisable to double-declutch, a manoeuvre which is aided by reasonably sensibly placed pedals. With 36 b.h.p. to move just over 10 cwt. along, the acceleration is more than brisk and the Sport Prinz will certainly never get in the way of other traffic.  Normal cruising speed is an indicated 60 m.p.h., while the needle will swing round to 80 m.p.h. on a slight downgrade, and a more fully run-in car (our test car had covered 1,500 miles) would probably reach the claimed 85 m.p.h. top speed. Remember, this car has a capacity of 583 c.c. ! 

On first acquaintance handling appears fussy but this is due to a combination of fairly firm suspension and rack-and-pinion steering having only 2.4 turns lock-to-lock. When the driver becomes more accustomed to the car he begins to fling it about in complete confidence, and although the Sport Prinz oversteers quite strongly it is difficult to make the rear end break away. 

On the open road it becomes a very pleasant car to drive . . . cornered with great verve . . . it is possible that the claimed 47 m.p.g. could be reached if a less aggressive driving technique was employed. The brakes of the test car required quite heavy pedal pressures and fade could be induced after two or three stops from above 60 m.p.h., but in normal use they appeared to be adequate. 

Rather expensive in this country the sporting version of these interesting economy cars from Neckarsalum will obviously find a limited market, but the man who wants to own a car of individual character could well consider the Sport Prinz. 

The magazine’s observation about expense was driven by the test car being priced at £970 – nearly twice that of the Prinz saloon.

 

An early-production (probably ’60) survivor is #4102499, sold for restoration in September ’24.

Two other ’60-made cars have featured in recent media coverage.  Another red one, chassis number unknown, is owned by a resident of Foley, a town to the North West of Minneapolis, U.S.  The owner’s experience with the car and details of his restoration work can found at https://www.oldcarsweekly.com/features/car-of-the-week-1960-nsu-sport-prinz.

Another, again finished in red, was recently photographed as body/paint restoration was concluding.  Location of this one was Astoria, New York, U.S.

The quality of classic car restoration standards has benefitted from technological advances in recent years, with some stunning results to be seen at the premier international concours events.  At the same time, an appreciation of ‘naturally aged’ cars and their patina has gathered momentum, generating interest in preservation as a principle just as valid as craft/artisan based restoration.  For those liking patina-porn, the ’62 Sport Prinz below will surely prove attractive.

The ’63 #4112286 displays the various badges/plate in rather better condition:

The car was sold by Artcurial in ’21 in Monaco for €7,748.  This was below an estimate of €10-15,000.  It appears to be in reasonable, usable condition, but the winning bidder was no doubt anticipating the need for substantial expenditure on a thorough restoration.  This would likely be fully justifiable given that the car apparently has no areas of very serious deterioration.

Produced the following year, #4122861 was offered by Osenat (Fontainebleau, France) in 2013 with an estimate of €5-7,000.  A successful, above-reserve bid was however not recorded.

Also a ’64 Sport Prinz, #4113783 was offered at auction in 2023, but the highest bid, €11,500, was short of the reserve.

#4117939 is unusual in being right hand drive.  First registered in the UK in ’65, it was apparently built to a factory ‘GT’ specification which included front discs and a reprofiled camshaft.  Much later, around ’08, a subsequent owner had the engine replaced with a 4 cylinder NSU unit.  At the same time chassis improvements were made and competition-use modifications – including a roll cage – were carried out.  There are also some bodywork alterations, most notably to the engine deck lid – Abarth GT style - to allow greater air intake/circulation for cooling purposes.  Engine performance is significantly increased at 52 bhp with peak torque of 53 lbs/ft.  Despite these various modifications and expenditures, the car made just a modest £6.900 when sold at auction in February ’24.

In contrast, #4119347, a ’66 car, appears to be a good example of a Sport Prinz in preserved standard specification.  Bonham’s lot description for its auction sale in ’18 includes the statement, ‘(the car was) comprehensively restored in 2004, though the interior was in such good condition that it was decided it did not need renovation and as a result possesses a lovely patina.’  It was estimated to sell for €18-25,000 but the reserve was apparently not reached.

Another inconclusive auction involved the ’67-manfactured #4118719, offered on Bring a Trailer in ’20.  High bid – unsuccessful – was $9.400.

The engine bay and front trunk of this car are in particularly pleasing condition:

Of the same age, #4117627 made for a more successful auction lot when offered also on Bring a Trailer in September ’20, selling for $16,040.

As with the immediately preceding car, a clean bay allows a good view of the engine’s simplicity and the ease of accessibility for service/repair work.  Given the modest power output, the deployment of twin coils – seen at the bottom of the photograph, might seem somewhat ironic!

Another ’67 car is #4121650 and, like #4117939, is right hand drive and used in the early years of the century for some historic rallying, though without any serious competition-related mechanical or bodywork modifications.  The car was sold in ’18 for £5,060.

Once again, a rhd/’67 Sport Prinz, #4121694 was sold in ’21 by Iconic Auctioneers for £8,769.  No other details are currently available, though the car appears to be in good, running condition, as seen below:

The latest-made, (’68), car of which I have a photograph is #4122062.  In describing the car for a sale in July 2012 of cars owned by the Prince of Monaco, Artcurial included a note about the interior: (It) 'has not been touched and offers all its period freshness, with its impeccable carpets, its two-tone cloth and leatherette seats with white piping, its delightfully sporty dashboard nicely painted, the steering in black bakelite with circular chrome-horn, chrome door handles and bellow-like door pockets.’  The hammer price realised was €25,023.

As seen in this survey, the NSU Sport Prinz does not generally command high values in the current classic car market.  A clear limitation is the modesty of motive power type since this not only makes for a vehicle with limited dynamic characteristics, but also robs it substantially of technical interest.  However, whilst the provenance, (ownership by the Monegasque monarchy), of #4122062 was no doubt a positive contributing factor, the price realised for this vehicle indicates the potential for well-preserved/original specification examples.
