For the 1991 season, team owner Guy Ligier had secured the use of V12 engines from Lamborghini, which had been used the previous season by Team Lotus and Larrousse. This was to be a stopgap measure as for 1992, the team were to use Renault V10s.
The JS35 chassis was prepared by Ligier's design department under the direction of Michel Beaujon, Claude Galopin and Richard Divila, the latter two being fired after the disappointing start to the season. The car was overweight and bulky from the start, not helped by the large oil tank required for the new engines. Changes to the suspension for the start of the European leg of the season helped performance a little. The chassis was later updated to a 'B' spec by new Ligier recruit Frank Dernie. The JS35B, which made its debut at the French Grand Prix also had some input from Gérard Ducarouge who was recruited mid-season.
Although Boutsen did not finish in the points during the season, he at least had the satisfaction of starting every race of the season, with a best qualification of 14th in Mexico. Comas failed to qualify three times, including the season opening United States Grand Prix. His best qualifying performance was at his home race in France where he started 14th. Boutsen's best finish was seventh, achieved twice in the early part of the season with the original car. Comas' best finish was in Canada where he finished eighth, having qualified 26th.
