The Lotus 91 was a Formula 1 racing car from the British racing team Lotus , which was used in the 1982 Formula 1 season .

Technical specifications

After the Lotus 88 was declared illegal by the FIA , team boss Colin Chapman had to contest the 1981 Formula 1 season with the Lotus 87 . As a result, the results remained below expectations. As a result, main sponsor Essex ended the arrangement with Lotus, which plunged the team into major financial problems. Only the successful negotiations with John Player Special led to an increase in the budget and made it possible for Chapman to design a new car with the Lotus 91.

The vehicle's monocoque was made of synthetic resin reinforced with carbon and aramid fibers . Outwardly, it was similar to its predecessor model, but had been fundamentally revised based on aerodynamic findings and was considered one of the best chassis in the field. Five chassis were built. However, the Lotus 91 fell short of expectations when compared to the competition with turbo engines .

The vehicle was powered by a Ford-Cosworth DFV engine, a water-cooled eight-cylinder V-engine with a 90 ° bank angle and a displacement of 2993 cm³. At a speed of around 10,750 rpm, it developed around 490 hp (360 kW). The engine ignition and injection system were from Lucas. The manually shiftable, longitudinally installed Lotus- Hewland transmission had five forward gears and one reverse gear. The tank held 191 liters. All wheels were individually suspended from double wishbones .

sponsor

The main sponsor was the tobacco company owned cigarette brand John Player , which is why the vehicle was black with gold applications.
