The Morris Mini-Cooper S with 1071 cc capacity had been on sale since March 1963 and it was joined by a further Cooper S model in spring 1964. This had a capacity of 970 cc. The very torquey engine of the 970 model delivered 65 h.p. at 6500 r.p.m. The small Cooper S provided an acceleration of 12 seconds to 100 km/h and a top speed of 155 km/h, giving the performance of a sports car. The 1000 production units required for homologation in the 1 litre class for the International Touring Car Championship was already achieved at the start of 1965, together with the twin brother Austin Mini-Cooper S and production then ceased. The low production run means that this is a rarity seldom seen on the roads today.
