Lotus 98T

The Lotus 98T was a Formula One car designed by Gérard Ducarouge and Martin Ogilvie and built by Team Lotus for the 1986 Formula One World Championship, a development of the 97T driven by Ayrton Senna and the newcomer Johnny Dumfries. A lower monocoque followed the rule cutting fuel capacity to 195 litres, and the Renault EF15B turbocharged V6 drove through a Hewland six-speed manual gearbox, with a five-speed also offered. Qualifying engines at unrestricted boost were claimed to exceed 1,000 horsepower, and race engines gave about 900. The car also had a two-stage ride height adjustment, water injection through the intercoolers and a fuel consumption microcomputer. It was the last Lotus with Renault power and the last in the black and gold of John Player.
