1961 Mini Cooper
Issigonis' friend John Cooper, owner of the Cooper Car Company and designer and builder of Formula One and rally cars, saw the potential of the Mini for competition. Issigonis was initially reluctant to see the Mini in the role of a performance car, but after John Cooper appealed to BMC management, the two men collaborated to create the Mini Cooper. The Austin Mini Cooper and Morris Mini Cooper debuted in 1961.
The 848 cc (51.7 cu in) engine from the Morris Mini-Minor was given a longer stroke to increase capacity to 997 cubic centimetres (60.8 cu in) increasing power from 34 to 55 bhp (25 to 41 kW). The car featured a racing-tuned engine, twin SU carburettors, a closer-ratio gearbox and front disc brakes, uncommon at the time in a small car. One thousand units of this version were commissioned by management, intended for and designed to meet the homologation rules of Group 2 rally racing. The 997 cc engine was replaced by a shorter stroke 998 cc unit in 1964. In 1962, Rhodesian John Love became the first non-British racing driver to win the British Saloon Car Championship driving a Mini Cooper.
A more powerful Mini Cooper, dubbed the "S", was developed in tandem and released in 1963. Featuring a 1071 cc engine with a 70.61 mm bore and nitrided steel crankshaft and strengthened bottom end to allow further tuning; and larger servo-assisted disc brakes, 4,030 Cooper S cars were produced and sold until the model was updated in August 1964. Cooper also produced two S models specifically for circuit racing in the under 1,000 cc and under 1,300 cc classes respectively, rated at 970 cc (59 cu in) and a 1,275 cc (77.8 cu in), both had a 70.61 mm (2.780 in) bore and both of which were also offered to the public. The smaller-engine model was not well received, and only 963 had been built when the model was discontinued in 1965. The 1,275 cc Cooper S models continued in production until 1971.
Sales of the Mini Cooper were as follows: 64,000 Mark I Coopers with 997 cc or 998 cc engines; 19,000 Mark I Cooper S with 970 cc, 1,071 cc or 1,275 cc engines; 16,000 Mark II Coopers with 998 cc engines; 6,300 Mark II Cooper S with 1,275 cc engines. There were no Mark III Coopers and just 1,570 Mark III Cooper S.
The Mini Cooper S won the Monte Carlo Rally in 1964, 1965 and 1967. Minis were initially placed first, second and third in the 1966 rally as well, but were disqualified after a controversial decision by the French judges. The disqualification related to the use of a variable resistance headlamp dimming circuit in place of a dual-filament lamp. It should be noted that the Citroën DS that was eventually awarded first place had illegal white headlamps but escaped disqualification. The driver of the Citroën, Pauli Toivonen, was reluctant to accept the trophy and vowed that he would never race for Citroën again. BMC probably received more publicity from the disqualification than they would have gained from a victory.
