Gerard Ducaragui and chassis specialist Michel Biscot had to start work on the model from scratch, as Matra refused to supply its engines to the French team, as well as due to changes in aerodynamics.
The team's designers managed to build a very tough and durable chassis using the principle of "internal aerodynamics" or the ground effect, which had just appeared then. It was installed, though inferior to the Matra engine in power, but significantly surpassing its reliability by the Ford Cosworth DFV engine.  .
The debut of this car was extremely successful. In the first two Grand Prix of 1979 , the team pilots won two poles , two wins, two lap records and one second place.
Soon, however, Ligier JS11 appeared strong rivals - the new Williams FW07 , heavy-duty Renault RS10 and fast and reliable Ferrari 312T4 . So in the middle of the year, the JS11 results noticeably decreased. Urgently revised aerodynamics and suspension of the machine. However, the desired improvement was not followed. Moreover, Patrick Depaye was seriously injured during a hang gliding flight, and Jacques X , who replaced the Frenchman, was able to score only a few credits. Points earned at the start of the season, was enough only for third place in the Cup of designers. 4th, 6th and 15th places in the individual competition.
Modification JS11 / 15 , which participated in the season of 1980 , outwardly differed only by the absence of the front wing. The changes also affected the rear and rear suspension. There were “fast” and “slow” body options for various types of tracks. In general, the new car was much more reliable than its predecessor and has maintained the reputation of an extremely high-speed and well-controlled car. However, various experiments with the design and the intense struggle of team-mates between themselves did not allow the team to achieve victories, either in the championship of pilots, or in the Constructors' Championship .
The JS11 chassis was the most successful in the history of the Ligier team . It was also used by Michelin for racing rubber tests. In just two seasons, Ligier pilots in 29 races scored 5 victories, won 7 poles and showed 6 fastest laps.
