Background

Due to rule changes in the World Sportscar Championship for 1992, Toyota was forced to replace their previous series of Group C engines, dubbed the R32-V and R36-V, which were 3.6L twin-turbocharged V8 engine units. The new rules required a 3.5L naturally aspirated engine to be used, similar to Formula One engine regulations at the time. Thus, in 1991, Toyota completed its RV10 engines and began early testing.^[4][5]

Due to the change in engines, a whole new chassis was also necessary in order to better handle the new V10. Former Tom Walkinshaw Racing designer Tony Southgate was in charge of designing the car that became the TS010, featuring a more aerodynamic and longer body than the C-V series of sportscars.^{[6][7][8][9][10][11][12]}
