Lotus 91: The 1982 Formula 1 Racer and Chapman's Final Victory
The Lotus 91 — the 1982 Formula 1 car built by Colin Chapman and his team. This was the last Lotus racer to win a race under Chapman's leadership. We delve into its technology and significance.
The Lotus 91 in brief
The Lotus 91 was the 1982 Formula 1 car, designed by Colin Chapman, Martin Ogilvie, and Tony Rudd. After a few unsuccessful or experimental seasons, Chapman decided to 'get back to basics'.
This is a race car, not a road model, so we'll cover its history and technology.
Technology
The car was powered by a Ford Cosworth DFV engine, with a standard Hewland gearbox. The racer was quite simple and easy to maintain; it was the first Lotus with carbon fibre brakes, which significantly improved braking.
The body was made from carbon fibre and Kevlar — after the McLaren MP4/1 and the Lotus 87 itself, this was the third car of the season made from this material to compete in F1. The car was sensitive to aerodynamic fluctuations, making it challenging to drive.
On the track
Elio de Angelis was particularly competitive in the 91 on fast circuits — at Hockenheim, Monaco, and the Österreichring. It was in Austria where he overtook the Williams driver Keke Rosberg on the final lap to win the race.
The victory, along with other results from de Angelis and Mansell's podium finish, helped the team end the season in fifth place. In 1983, with ground effect banned, the 91 was replaced by the first Lotus turbo car.
Legacy
This was the last Lotus F1 car to win a race under Colin Chapman's leadership — on December 16, 1982, Chapman died of a heart attack.
The Lotus 91 served as the basis for the Lotus 92 — the first F1 car with active suspension. Surviving examples belong to collections and historical racing participants; acquiring one as a regular car is impossible.
