Keith Duckworth

Duckworth served his two years of national service with the Royal Air Force, during which time he briefly trained to become a pilot but was grounded for dangerous and incompetent flying and was reclassified as a navigator.

[2] Duckworth claimed that allergy to medication he was receiving caused his flying problem - in civilian life he became a keen light aircraft and helicopter pilot.

After completing his tour of duty, which he finished as a navigator, Duckworth studied engineering at Imperial College London, earning a BSc degree in 1955.

Costin was obliged to remain with Lotus, having recently signed a restrictive contract; for the first few years Duckworth worked essentially alone at Cosworth until Mike could join him.

The DFV's last race was the Austrian Grand Prix, held on the fast Österreichring circuit, where driver Martin Brundle failed to qualify the underpowered car.

The DFV's last win was at the 1983 Detroit Grand Prix with Italian driver Michele Alboreto piloting his Tyrrell 011 to a surprise, but popular victory.

It was at the 1984 British Grand Prix at Brands Hatch that Duckworth and Ford finally agreed to build a turbo powered engine to replace the DFV.

The new 850 bhp (634 kW; 862 PS), 120° Ford-Cosworth TEC V6 turbo engine (internally dubbed the GBA), made its debut at the 1986 San Marino Grand Prix in the Team Haas (USA) Ltd entered Lola THL2, the car driven by 1980 World Champion Alan Jones.
