From the Mexican Grand Prix onwards, Larrousse entered a second car for Yannick Dalmas who qualified 23rd, outpacing his more experienced team-mate Alliot, who started the race 24th. The team enjoyed their best race of the season so far as Alliot claimed another class win and World Championship point with a sixth-place finish. Dalmas finished ninth, taking Lola to second in the Colin Chapman Trophy. In the Jim Clark Cup, Alliot moved up to third with Dalmas sixth. They did not fare as well in Japan however, as although Alliot and Dalmas started 18th and 22nd, Alliot was pushed into the wall during a multiple startline pile-up involving Arnoux and Michele Alboreto, and Dalmas suffered engine troubles on the way to finishing 14th, four laps adrift of the winner.
