Nissan R90C

The Nissan R90C was either of two Group C racing cars built in 1990 for Nissan Motors for competition in World Sportscar Championship (WSC) based in Europe and the All Japan Sports Prototype Championship (JSPC). The cars based on the basic R90C platform would compete until 1993 before Nissan chose to withdraw from sports car racing, not returning until 1997. It won three JSPC championships as well as several significant endurance races during its career.

Development

Mechanically, the R90Cs shared much with their predecessor, the R89C. Most of the chassis construction was the same, as well as the mechanical layout. The Nissan VRH35Z 3.5 litre twin-turbo V8 that had debuted in the R89C was proven successful and kept as part of the R90C's design. Although mechanically similar, the cars were nearly all new constructions, leading to chassis builder Lola Cars International terming the cars T90/10, while the R89Cs had been T89/10.

Unlike the R89C, Nissan felt that the car was a compromise. At the time, Nissan competed with the R89Cs in both the World Sportscar Championship and All Japan Sports Prototype Championships.
