Team: Team Lotus

Designer: Gérard Ducourage
Drivers: Elio de Angelis (11), Nigel Mansell (12)
Team name: John Player Team Lotus

The Lotus 95T is an evolution of the previous Lotus of 1983. The major change in design came with fuel regulation changes that limited the maximum amount of fuel to be carried by a car. During the year, Mansell and de Angelis showed excellent pace with the Lotus 95T but suffered serious reliability problems.

While this car was possibly the best of 1984, its tyres were not as the team's switch to Goodyear proved not to be the best choice. It turned out that the tyres were inferior to both Goodyear and Pirelli. The drivers were unable to record a victory but did manage 6 podium finished and two pole positions. Lotus finished 3rd in the constructors' championship of 1983, behind McLaren and Ferrari.
