A new 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 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 100kph from a standstill in 7.7 seconds.The 2.6 L engine was detuned in September for the deluxe version 2600 GT, with 2550 cc and a double-barrel Solex carburettor. Germany’s Dieter Glemser won the Drivers’ title in the 1971 European Touring Car Championship at the wheel of a Ford Köln entered RS2600 and fellow German Jochen Mass did likewise in 1972.
