The Ford Cosworth DFV engine first appeared at the Dutch Grand Prix in 1967, powering the Lotus 49s of Graham Hill and Jim Clark. Hill claimed pole position, and Clark won the race - a remarkable debut for an engine that went on to become the most successful ever in Formula One. The DFV won a remarkable 155 Grands Prix, the last of which was in 1983, 16 years after its debut. Published to coincide with the DFV's 40th anniversary, this beautifully produced book tells the full story of this remarkable engine's development and evolution.
