In 1966, Colin Chapman of Lotus Cars was the founder and principal of Team Lotus. He got Ford to finance Keith Duckworth's design for a new lightweight 3.0 litre Formula One engine. Cosworth received the order along with £100,000 from Ford. The contract told Duckworth to build a four-cylinder Ford-based F2 engine to prove it would work (see the FVA above). After that, a pure Cosworth V8 would be built. The DFV design used a similar cylinder head to the one on the FVA engine with custom cylinder block and crankcase. This created the legendary DFV - literally meaning "Double Four Valve". This engine, and its version were used for a quarter of a century. It was the most successful engine in the history of Formula One / Grand Prix motor racing. With 167 winning races it put Cosworth Engineering on the map. Although designed for Formula One, the engine has been modified for use in many other areas.
