The Hesketh 308C was a Formula One racing car designed by Harvey Postlethwaite and used by Hesketh Racing in the latter stages of the 1975 Formula One season. The car featured the rubber suspension which Postlethwaite had pioneered on the preceding 308B model and a Ford-Cosworth DFV engine. In 1976, the car was acquired by Wolf–Williams Racing and rebranded as the Wolf–Williams FW05.
