Background
The classic Mini Cooper needs no introduction. Famous for the integrity of its engineering, handsome looks and giant-killing handling, it slew all before it, winning praise from drivers, vanquished competitors, pundits, and spectators alike, all of whom have kept it close to their hearts ever since.
The original 1961 version was humble, taking the standard Mini’s 848cc engine, albeit with a slightly longer stroke, to create the first dedicated Cooper engine, the 997cc. With twin SU carburettors it developed 55bhp, or 21bhp more than the engine upon which it was based. This, along with its miniscule kerbweight, close-ratio gearbox and disc brakes on the front axle, enabled it to humble far more powerful machinery.
A shorter-stroke, higher-revving 998cc Cooper engine arrived in 1964, shortly after the introduction of the high-performance Cooper 1071S, the version that is possibly the most revered Cooper of them all.
Only the cognoscenti will spot the relatively discreet ‘S’ badging front and rear – until the driver hurls the Cooper S at the horizon with unlikely fury on its way to a top speed of 95mph. But the real reason for its success in the hands of folk like Paddy Hopkirk was that most corners could be taken flat…
Two new Cooper S models were introduced in 1964. Aimed at separate motorsport classes, they had either a 970cc or a 1275cc engine under the bonnet. Visually much the same as the 1071S, the 1275 was fitted with hydrolastic suspension along with the rest of the Mini range from late 1964 and continued in production until 1967 with stocks finally running out in 1970.
