Morris Mini Cooper S Side (1971)

In line with the rest of the Mini range the Cooper models received the Mk II updates in 1967 consisting of a squarer grille, larger rear window and larger rear lamps. The Cooper S retained the twin carb 1275cc engine which now produced a lively 76bhp. Other improvements included twin fuel tanks, an oil cooler and modified drive shafts.

In 1969 the Mk III Mini range took over, improvements included wind down windows and were now badged as "Mini" rather than Austin or Morris. The Mk III Cooper S lasted until 1971 when it was discontinued much to the disappointment of Mini Cooper fans everywhere.

The Mini Cooper certainly caught the motoring worlds imagination during the Sixties notching up many Rally successes to its credit. Many consider the Cooper S to be the ultimate Mini variant, it originally appeared in 1963 powered by the 1071cc A-series engine and included servo assisted disc brakes.

The Cooper S Mk I came with the 1071cc A-series engine from 1963-64, the 75bhp 1275cc engine was introduced in 1964. A 970cc Cooper S joined the range in >1964 as a "homologation special" so that the Cooper could compete in the 1000cc racing series, this variant only stayed in production for one year.

In 1967 the Cooper S received the Mk II Mini improvements in line with the rest of the range, for many enthusiasts the Mk I Cooper S is still the Definitive performance Mini.
