The JS21 created by Claude Galopin featured the aluminium monocoque chassis and Ford Cosworth DFV 3.0 litre normally aspirated engine, while the majority of teams used turbo power. The 1983 season was the first year for Ligier when the team failed to score any points. Two new drivers of the team, veteran Jean-Pierre Jarier and Brazilian novice Raul Boesel scored a lot of retirements with the 7th place as the best result for both of them. Boesel, who generally was outperformed by Jarier, took 7th place in the USA West Grand Prix, and Jarier was 7th in Austria. The scale model from the “Brazilian Legends” Collection represents the Boesel’s car from the Belgian Grand Prix where he was 13th at the finish. The 1983 season was the second and last for the Brazilian driver in Formula 1. Later he moved to Indy Car where he raced during 16 seasons (1985 – 2002), but scored no wins.
