TheLigier JS33 was aFormula One car used by theLigier team during the1989 Formula One season. Its best finish in a race was fifth, at the1989 Canadian Grand Prix. The JS33 was updated to a 'B' spec for use in the following season, but failed to score any points for the team.
For the 1989 season, Ligier switched from theJudd engines of the previous season toCosworth DFR. The JS33 chassis was designed byMichel Beaujon and finished off byRichard Divila.[2] In appearance, it looked similar to theMarch 881 and even used the same gearbox (purchased fromMarch).[3]
The chassis was updated to a 'B' spec for the1990 Formula One season. The March gearbox from the previous season was discarded in favour of an X-trac unit,[4] and the front suspension was revised. Weight was also shaved from the car.[2]
Ligier's lead driver from the previous season,René Arnoux, remained with the team and alongside him was new recruitOlivier 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 theMonaco 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 theCanadian Grand Prix.[1]
Grouillard was usually the faster of the two Ligier drivers. His best qualification performance was at theSan Marino Grand Prix where he was 10th on the grid. He was disqualified from the race after his team worked on his car prior to a restart of the race. His best finish of the year was 6th, at theFrench Grand Prix. Grouillard left the team at the end of the season. Ligier finished 13th equal in the World Constructors' Championship with three points, an improvement on the previous year.[1]
Nicola Larini andPhilippe Alliot were Ligier's drivers for the 1990 Formula One season. Larini was a reliable driver for the team, finishing all but three of his races. He did not score any points and his best finishes were back to back seventh places at theSpanish andJapanese Grand Prix. Alliot had some unfortunate races; he was excluded from theopening race in the United States when a mechanic worked on his car outside of the pits and he was disqualified from theGerman Grand Prix when he received a push start on the first lap of the race.[5]
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.[6]
