14 mm and an equidistant of 2 mm. Compression is 8.5, and the fuel required is petrol with an octane rating of 91 RON. The Spider's engine had "teething troubles", but is a compact, smoothly running engine with a decent power output. Rated power was initially 37 kW (50 hp) at 5,500 rpm. In later models, rated power was 40 kW (54 hp) at 6,000 rpm. Maximum torque output is 79 newton-metres (58 lbf⋅ft) at 3,500/min, equivalent to a BMEP of 1 megapascal (145 lbf/in). It was later found that the characteristics of critical materials selected and applied by NSU to build production rotary engines were inappropriate to the stresses they would bear, and rotary-engined cars earned a reputation for unreliability. Engines required frequent rebuilding to replace worn apex seals,and warranty costs associated with installation of the engine in

In 1966, Al Auger of
Richmond, California, became the first person to race a Wankel-powered production car in an officially sanctioned race. After only installing a mandatory roll-bar and racing tires on an NSU Spider, Auger raced in 1966 and 1967 in Sports Car Club of America sanctioned road races

The NSU Spider is the first series production car powered by a Wankel rotary engine. In the Spider, a KKM 502 single-rotor engine with a single spark plug was used; it displaces 996 cubic centimetres (61 in) from a generating radius of 100 mm, a width of 67 mm, an eccentricity of

The engine bay had originally been designed to take the four-stroke air-cooled two-cylinder engine from the NSU Prinz. The rotary unit was much more compact permitting a shallow luggage locker fitted above it. This compensated for a reduction in luggage space at the front of the car because of the

coupé introduced in 1959. In addition to the folding roof, the Spider was distinguishable from the hard top car by a grill at the front. As with all NSU cars at the time, the engine was rear-mounted: in order to improve weight distribution, space was found for the Spider’s radiator and for its

Large sales volumes were never envisaged for the car, and this was reflected in a relatively high retail price, USD$ 2,979. Between 1964 and 1967 2,375 were built. In 1967, the model was withdrawn and NSU's second rotary-engined production saloon was presented. The
