The Ford Capri is a fastback coupé built by Ford Motor Company between 1968 and 1986, designed by American Philip T. Clark, who was also involved in the design of the Ford Mustang. It used the mechanical components from the Mk2 Ford Cortina and was intended as the European equivalent of the Ford Mustang. The Capri went on to be a highly successful car for Ford, selling nearly 1.9 million units in its lifetime. A wide variety of engines was used in the Capri throughout its production lifespan, which included the Essex and Cologne V6 at the top of the range, whilst the Kent straight-four and Taunus V4 engines were used in lower specification models.
A 2637 cc version of the Cologne V6 engine assembled by Weslake and featuring their special all alloy cylinder heads appeared in September 1971, powering the Ford Capri RS2600. This model used Kugelfischer fuel injection to raise power to 150 PS (110 kW) and was the basis for the Group 2 RS2600 used in the European Touring Car Championship. The RS2600 also received modified suspension, a close ratio gearbox, lightened bodywork panels, ventilated disc brakes and aluminium wheels. It could hit 100 km/h from a standstill in 7.7 seconds.
