Guy Ligier had good reasons to feel confident (picture above) that his two drivers, Patrick Depailler and Jacques Laffite, will perform well in the 1979 season.
It was the first time, since he launched the Ligier F1 team in 1976, that Guy Ligier secured enough budget, mainly from cigarette brand Gitanes and petroleum company ELF, to field a second car for Patrick Depailler, who he lured away from Tyrrell.
The deal with engine supplier Matra ceased in 1979 and Ligier built a Cosworth-powered wing-car, the Ligier JS11. The car designed by Gérard Ducarouge was hyper competitive and began the season winning in Argentina and in Brazil in the hands of Laffite and seemed unbeatable.
However, the JS11 faced serious competition when Williams and Ferrari introduced aerodynamically improved cars, and besides one win in Spain for Depailler (picture below), the rest of the season was less successful for the French team. Jody Scheckter and Ferrari won the Drivers’ and Constructors titles.
