An insight into the design, engineering, maintenance and operation of the fastest, most powerful Lotus F1 cars ever raced. The Lotus 98T was the 1986-season, JPS-liveried F1 car driven by Ayrton Senna and team-mate Johnny Dumfries. Senna took eight podium positions, including two wins in the car, taking the fight to the superior McLarens and Williams. The 98T was one of the ultimate incarnations of an F1 car, powered by a Renault V6 turbo engine, which is conservatively estimated to have produced up to 1,300bhp at full boost. Senna was mighty to behold at the wheel of the 98T - he took pole position at eight of the season's 16 races, with victories in Spain and Detroit, famously crossing the line alongside Nigel Mansell in Spain, to win by 0.014s. This Manual, extensively illustrated with both period images and photographs of a recently restored car, provides a fascinating insight into the design, evolution, operation, maintenance and restoration of the Lotus 98T and its Renault-turbo-powered predecessors.
