[3] The car was powered by the Renault Gordini EF1 V6-turbo engine, and ran on Pirelli tyres.

It featured a lower, slimmer monocoque with improved weight distribution over its predecessor.

The 94T made its debut at the 1983 British Grand Prix and proved to be competitive in the hands of Nigel Mansell, who came home fourth in the race, and Elio de Angelis, and provided an upswing in form for the Lotus team which would carry them into the 1984 season with a developed version of the car.

Its best result was a third-place at the 1983 European Grand Prix with Mansell, who also claimed the fastest lap in the race, while de Angelis won the pole position.
