Introduction

Launched in October 1987 for the French Supertouring Championship, the Renault 21 4x4 project claimed its first podium finished barely five months later in its first race. In the end, Jean Ragnotti and Jean-Louis Bousquet went on to win six of the ten races on the calendar, an impressive, almost unbelievable feat given that the car represented a genuine technical revolution! Meticulous work had been done in wind tunnel testing on the car’s aerodynamics. Mechanically, the car featured a new 430 hp engine, the power of which was curbed by a blow-off valve taken from F1™, and a 2.35m-long carbon fibre driveshaft. A well-designed car that was incredibly effective!
