The JS11 and its successors made Ligier one of the top teams through the early 1980s. Despite substantial sponsorship from Talbot and public French companies - mainly SEITA, Gitanes and Française des Jeux - the competitiveness of the team began to decline around 1982. Around this time, they were testing a Matra V6 turbocharged engine, which never raced.
Thanks to the political support of Ligier long-time friend François Mitterrand, in the mid-1980s, the team benefitted from a free Renault turbo engine deal
