The 'Mini Cooper' was introduced as the 'Austin Cooper' or the 'Morris Mini Cooper' in October 1961 with 55bhp 997cc version of the 848 A-series engine with twin carbs. In March 1963 a new 'Cooper S' model was launched with a 1071cc 70bhp engine and larger 7.5inch discs. In 1964 there was a 970cc Cooper S (for 1-litre racing) and the 1275cc Cooper S 76bhp was launched. The ordinary Mini Cooper is now given a 998cc engine already used in the Riley Elf/Wolseley Hornet but with twin carbs and 7inch disc brakes. In September 1964 Hydrolastic suspension replaces the rubber cone suspension. In Italy the Innocenti Mini Cooper first goes on sale in 1966. In October 1967 MkII Minis are announced, gain a larger rear window, larger rear lamps. Mk III Minis are announced in October 1969 and lose the 'Austin' and 'Morris' brands, becoming simply 'Mini' and gaining concealed door hinges and wind-up windows. Hydrolastic suspension is lost to rubber cone suspension except on the 1275-engined cars. The new Clubman models replace the Elf and Hornet, and the 1275 GT is set to replace the Mini Coopers although the Cooper S does continue as the 'Cooper S MkIII' until July 1971. The 'Cooper' name is abandoned in 1971 because the contract has run out and British Leyland don't believe they need it any more. However, special edition Minis bearing the 'Cooper' name are being sold from 1990 onwards.
