Development

The JS21 was designed by Claude Galopin under the technical direction of Michel Beaujon. Henri Durand worked on the car's aerodynamics.[1] Having used Talbot engines for the previous two seasons, the JS21 was designed to be powered by a Ford Cosworth DFV.[2] Ligier was the first choice to be the recipient of the then-new Honda turbo engine due to team owner Guy Ligier's longstanding relationship with Honda but the team declined to use it.[3] The first three JS21 chassis were converted from the previous year's JS19, with four in total being built.[2]

Racing history

The Ligier team recruited two new drivers for the 1983 season, Jean-Pierre Jarier, who had a single outing for the team back in 1977, and Brazilian novice Raul Boesel. Jarier qualified for every race with a best grid placing of 9th, at the Monaco Grand Prix. His best finish was 7th in Austria. For most of the season, Boesel usually qualified several places behind Jarier but improved towards the season's end although he did miss qualifying for the Austrian and Italian races. His best qualifying was 17th, in the season opening Brazilian Grand Prix, and he achieved his best finish of 7th the following race in the United States.[1]

1983 was the first season in the team's history that it failed to score a single point. For the following year, team owner Guy Ligier secured the use of Renault V6 turbocharged engines.[2]

gollark: It is *annoying* that despite being several thousand to million times faster than old stuff, my laptop is still not notably faster on general-purpose tasks.
gollark: Reject modern computers, return to bare-metal BASIC on 16-bit machines or something.
gollark: It does have a GPU now, though, as I wanted to run GPT-2 slightly faster and was able to obtain a bad one which technically supports CUDA.
gollark: My server is only mildly more powerful than my laptop and has half the RAM, so mostly I just suffer.
gollark: I don't think it's a very good idea, internet connections generally aren't that fast and reliable.
