The Ligier JS5 marked Ligier's inaugural entry into Formula One competition, engineered by Gérard Ducarouge. Participating in the 1976 Formula One season, it accumulated 20 points and achieved sixth place in the Constructors' Championship standings. The JS5 also secured the first pole position for both driver Jacques Laffite and the Ligier team at the 1976 Italian Grand Prix held in Monza.
Background
French businessman Guy Ligier, who had amassed wealth through his construction ventures and briefly competed as a Formula One driver during the 1960s, established a motorsport company in 1969. This firm produced sports cars such as the JS2, which competed at Le Mans in 1972. By late 1974, with financial support from French tobacco company SEITA, Ligier recruited designer Gérard Ducarouge from Matra to create a Formula One car.
Design and development
The JS5 was developed by Ducarouge alongside Michel Beaujon as a traditional long-wheelbase aluminium monocoque chassis. It was powered by the Matra MS73 V12 engine, previously utilized in sports car racing, with the vehicle completed in October 1975. Its initial presentation took place at SEITA’s Paris headquarters before undergoing testing at Circuit Paul Ricard. Jacques Laffite was selected as the driver following brief consideration of Jean-Pierre Beltoise.
At first, the JS5 was distinguished by a prominent airbox—leading to its nickname "Teapot"—but subsequent rule modifications after the 1976 Spanish Grand Prix resulted in a much smaller airbox and repositioning of the rear wing. Aerodynamic refinements were introduced with the second chassis, featuring less pronounced body curves compared to the original.
Racing history
The JS5 made its competitive debut at the 1976 Brazilian Grand Prix, where Jacques Laffite qualified 11th but retired from that race and also from the next event in South Africa. At the third round in Long Beach, Laffite finished fourth, awarding Ligier its first championship points. He achieved his maiden podium finish by placing third in Belgium.
Laffite continued to perform well, securing fourth place in Sweden and improving further at Austria with an updated chassis, finishing second. He also earned a third-place finish in Italy after claiming pole position.
Ligier concluded the season sixth overall in the Constructors' Championship with a total of 20 points, while Laffite ranked seventh in the Drivers' Championship.
