Ligier JS31

It was driven by French veteran René Arnoux, in his third season with the team, and Swede Stefan Johansson, who joined from McLaren.

Johansson joined the team late in the off-season in place of West German Christian Danner, who had originally signed to drive but was unable to fit in the car comfortably.

[3] The JS31 was the first non-turbo car produced by Ligier since the Cosworth DFV powered JS21 used in the 1983 season and it proved to be very uncompetitive.

Johansson, a frequent podium visitor in the previous three seasons, failed to qualify six times and never finished above 9th while seven-time Grand Prix winner Arnoux failed to qualify twice (San Marino and France) and never finished a race higher than 10th.

Neither driver qualified for the San Marino Grand Prix, the first time in team history that neither of its cars made the grid.
