History

The NSU Sport Prinz was a Air-cooled rear engine rear wheel drive 2-cylinder 2+2 two door coupe.It is not going too far to suggest that the little NSU Sport Prinz was really a sheep in wolf's clothing, as its very stylish fastback Bertone coupe body concealed nothing more dramatic and effective than a two-cylinder 598cc engine.

For all that, it was still quite a notable little car, which found its own limited but steady market. Initially, the sports prince had the air-cooled twin-cylinder engine of Prince II, but with an increased output of 20 to 30 hp (22 kW) and a maximum torque of 4.5 mkg (44 Nm) at 3500 / min. This performance remained unchanged, as the beginning of 1961, the displacement increased from 583 to 598 cc. The maximum speed of the 565 kg heavy car was about 120 km / h.

The Prinz itself was NSU's own minicar design of the 1950s and, in the manner of the day, had a rear-engine layout. The Prinz, however, had its parallel twin-cylinder water-cooled engine mounted transversely behind the line of the final drive. The original car was an ugly little beast, and the Corvair-styled Prinz IV of 1961 came along after the Bertone coupe was finished. It was therefore quite remarkable that Bertone even took the trouble to make this silk purse out of what was undoubtedly a sow's ear.

The car's engineering was in steel, based on the pressed-steel floorpan of the at first. saloon, and included four-wheel independent suspension. Front wheel disc brakes were added to the specification from 1965.The chassis of the sports prince first came from Prince II . In autumn 1960, however, the coupe received the Prinz III chassis with longer suspension travel, front stabilizer and rubber extension springs the distribution of weightwas 44% to front axle,and 56% at rear axle. In 1964, it was adjusted to the Prince 4 and received at the front axle disc brakes instead of the previous drum brake Although not commercially important itself, it was significant because Bertone developed a spider version, and this was given the single-cylinder NSU Wankel engine to become the world's first Wankel-engined car to be sold commercially.
20,831 were built by then, of which 2,715 at Bertone.
