Hesketh 308
Lord Hesketh's unsponsored, rubber-sprung racer that gave James Hunt his first Grand Prix win.
About the Hesketh 308
Harvey Postlethwaite designed the 308 for Hesketh Racing to replace the team's March 731, loosely basing it on the March and powering it with the Cosworth DFV. Looking for simple, light progressive springing, Postlethwaite adopted rubber springs made from a special non-creep rubber developed by the Malaysian Rubber Producers Association, fitted from the 1975 Argentine Grand Prix. James Hunt put it on pole on its debut at the 1974 Race of Champions and won that year's non-championship International Trophy at Silverstone, though transmission failures blunted its first season. Updated as the 308B, it carried Hunt to victory in the 1975 Dutch Grand Prix at Zandvoort, the team's only win, and Hesketh finished fourth in the Constructors' Championship before running out of money at the end of the year.
