Ligier JS33

For the 1989 season, Ligier switched from the Judd engines of the previous season to Cosworth DFR. The JS33 chassis was designed by Michel Beaujon and finished off by Richard Divila. In appearance, it looked similar to the March 881 and even used the same gearbox (purchased from March). The chassis was updated to a 'B' spec for the 1990 Formula One season. The March gearbox from the previous season was discarded in favour of an X-trac unit, and the front suspension was revised. Weight was also shaved from the car. ==Race history==

1989 season Ligier's lead driver from the previous season, René Arnoux, remained with the team and alongside him was new recruit Olivier Grouillard. Arnoux, in his final season in Formula One, did not start the year well, failing to qualify for the first two races of the year before making the grid in the Monaco Grand Prix in 21st spot. He went on to finish the race in 12th. He continued to struggle during qualifying, only making the grid on eight more occasions. He finished in the points once, with a fifth-place finish at the Canadian Grand Prix. With more cars than spaces available on the grid, some teams had to enter pre-qualifying in order to be allowed to participate in qualifying proper. With neither driver scoring points by the midpoint of the season, Ligier was relegated to having to pre-qualify from the German Grand Prix. However, this only lasted for a few races before one of the seeded teams, Onyx, withdrew from Formula One, allowing Ligier, as the best placed unseeded team, direct entry into qualifying. ==Complete Formula One results==
