1963 Austin Mini Cooper S

BY 1963 the BMC Competition department knew what they wanted to do with the Mini. Their efforts culminated in the 1963 Austin Cooper S and Morris Cooper S. Besides a host of upgrades, the primary difference was a specially cast engine block and cylinder head that was more suitable for racing.

The first Cooper S models used a 1071 cc engine with a special nitrided steel crankshaft. In 1964 a range of displacements was offered including 971 cc and a 1275 cc.

For extended trips and rally racing, a second fuel tank was fitted. Other factory upgrades included larger front disc brakes, a vacuum-assisted brake booster and offset steel wheels which were widened to 4½ inches by 1964.

Despite only having around 75 bhp on tap, the Minis were very successful in Group 2 Rally racing, winning the Monte Carlo Rally outright.
