Renault 21 Superproduction (1988)

Launched in October 1987 for the French Supertouring Championship, the Renault 21 Superproduction claimed its first podium finish in March 1988, just over five months later!

The car won ended up winning six of the ten races on the calendar, shared equally between Jean Ragnotti and Jean-Louis Bousquet. At the end of the season, Jean Ragnotti claimed the French Championship drivers’ title in the superproduction class.

Meticulous work had been done in wind tunnel testing on the car’s aerodynamics, in order to find the most effective solutions. Mechanically, the car featured a new 430hp engine, the power of which was curbed by a blow-off valve derived from F1, and a 2.35m-long carbon fibre driveshaft taken from the Espace Quadra.

Whilst this well-designed car crossed swords with the best in Europe, beating the Germans on their home soil, Renault developed a slightly less powerful version for the Renault 21 Turbo Europa Cup, which proved to be very successful.
