1966 NSU Prinz Spider Wankel

The NSU Spider is an automobile produced from 1963 to 1967 by NSU Motorenwerke AG.

The Spider was the world's first Western production car powered by a Wankel rotary engine. Its water-cooled single-rotor engine and standard front disc brakes distinguished it from other cars of the same type from that period. The bodywork was designed by Bertone.

The NSU Spider was the first series-produced car to be powered by a Wankel rotary engine. It uses a single-rotor KKM 502 engine with a single spark plug. The engine has a displacement of 996 cm³ (61 in³), a generating radius of 100 mm, a width of 67 mm, an eccentricity of 14 mm, and an equidistance of 2 mm. The compression ratio is 8. 5, and the required fuel is 91 RON petrol. The Spider's engine had "teething problems," but it is a compact, smooth-running unit with a reasonable power output. The initial rated power was 50 hp (37 kW) at 5, 500 rpm. In later models, the rated power was 40 kW (54 hp) at 6, 000 rpm. Maximum torque is 79 N⋅m (58 lbf⋅ft) at 3, 500 rpm.

This car is a beautiful NSU Spider, white with red and black upholstery. The paint is still in very good condition, and the engine runs nicely. Furthermore, it shifts well, steers well, and brakes properly. It is a special NSU with a very special Wankel engine.

This car has an Italian registration.
