The Ligier JS21 was a Formula One racing car manufactured and raced by Ligier during the 1983 Formula One season. Powered by a Cosworth V8 engine while the majority of teams used turbo power, the team failed to score any points.
Development
The JS21 was designed by Claude Galopin under the technical direction of Michel Beaujon. Henri Durand worked on the car's areodynamics.[1] Having used Talbot engines for the previous two seasons, the JS21 was designed to be powered by a Ford Cosworth DFY. The first three JS21 chassis were converted from the previous year's JS19, with four in total being built.[2]
