The Ligier JS7 represented the second Formula One vehicle engineered by Equipe Ligier. Continuing the tradition set by its forerunner, the JS5, the "JS" label paid tribute to Jo Schlesser, a close friend of founder Guy Ligier who had passed away.
Distinguishing itself from the typical Ford Cosworth powerplant, the JS7 was equipped with a Matra V12 engine. This was combined with a Hewland six-speed manual transmission and adopted a standard longitudinal engine configuration alongside wishbone suspension. The design replaced the JS5's prominent air intake with a sleeker profile, while its front wing bore resemblance to that of the Ferrari 312T.
The car competed throughout the 1977 season and in early 1978 events. It underwent a brief revision known as the JS7/9 before being replaced by the Ligier JS9. A highlight of its history was Jacques Laffite’s triumph at the 1977 Swedish Grand Prix, which became the inaugural all-French victory in World Championship racing—encompassing chassis, engine, and driver.
