Renault 21 Turbo 4x4 Superproduction Race Car in action at Goodwood Festival of Speed!

A couple of months ago I shared with you a video about a R21 Europa Car, a machine built by Renault in order to be race in their own one-make series: the Europa Cup. Now I'm sharing with you a brief video about the ultimate Renault 21 ever built: the Superproduction/SuperTourisme.

The project was launched in late 1987 and its race debut was in March 1988. The car was based on the street-legal 4WD Renault 21 (called 'Quadra') but all its technical characteristics were new. The Superproduction saw an all-new 2.0-litre turbocharged 4-cylinders engine producing 430 hp that could reach up to 290 km/h. Other innovations included a blow-off valve derived from F1 and a 2.35m-long carbon fibre driveshaft taken from the Espace Quadra and wind tunnel tests resulted in highly effective solutions for the car's aerodynamics. A meticulous study of all the vehicle's technical specifications made the 2-litre 4x4 R21 the best car of the 1988 season.

Over the course of the 1988 season, six of the 10 calendar races were won, with victories shared between Ragnotti and stablemate Jean-Louis Bousquet. Those victories saw Ragnotti claim the French Championship drivers’ title in the Superproduction class. New rules for the 1989 Championship that limited boost pressure to 2 bars were unfavourable for the Renault 21’s turbo engine. As a result, the team made a number of modifications to the car, resulting in an entirely different model to the previous year’s, with a longitudinal engine configuration closer to that of the original production car. Despite a handicap of 128 kg and transmission issues, the car took 11 poles from 14 races and came second in the championship.

Watch it in action on Goodwood's hillclimb course during the 2019 Festival of Speed!
