Here's why the Cosworth DFV is one of racing's greatest engines.
It might be impossible to name the greatest racing engine of all time, but the Cosworth DFV certainly makes a case for itself. Introduced in 1967 bolted to the monocoque of a Lotus 49, the DFV, a 3.0-liter V-8, racked up 155 Formula 1 victories over a period of 16 years, and powered 12 driver's titles and 10 constructor's titles. Turbocharged, it dominated IndyCar, with 10 Indy 500 victories in a row. It even won Le Mans in 1975 and 1980.
Chapman knew Duckworth was the guy to build an engine, despite Cosworth never building a Grand Prix engine before. Lotus couldn't afford the project on its own, so in stepped Walter Hayes, who provided £100,000 of Ford's money to build the engine, in exchange for branding rights. With hindsight, a bargain considering the millions spent on the GT40 program. Around the same time, Duckworth was laying the groundwork for a new F2 engine, as a 1.
."[He was] a stickler for having it right and pursuing all avenues in design. He was very good at problem solving."These days, we're used to modularity in engine design, where inline-three, -four, and -six cylinders can be made up of the same basic components, and where a V-8 can be born from two four-cylinders. Duckworth was long unconvinced that a DFV could be made up of two FVA, but he eventually came around. Even still, there are many differences.

Formula 1 probably wouldn't have survived the fuel crises of the Seventies and sustained huge grids were it not for the availability and affordability of the DFV. By the mid-Seventies, a vast majority of the grid was DFV powered, with only the likes of Ferrari, Matra, and Alfa Romeo providing 12-cylinder alternatives. All the while, Duckworth and the team at Cosworth continued to refine the engine, improving reliability and power.
