 In 1990, when fellow team Larrousse were disqualified after claiming their chassis was built by themselves, while in fact it was built by Lola Cars, Ligier moved up into 10th place in the Constructors' Championship, which gave them subsidized travel benefits, despite actually not being classified due a to lack of points.In 1993 the team enjoyed an upswing when Guy Ligier sold the team to Cyril de Rouvre after a disappointing 1992 season when they once again failed to fulfil their potential despite being supplied with the same works Renault engines as the dominant Williams team.Surprisingly, the team was somewhat more competitive during this period, in part due to the talents of aerodynamicist Frank Dernie and engineer Loïc Bigois.
