The success story of the little "racer" continued with the second version of the Morris Mini-Cooper from January 1964. The 998 cc engine from the Mk II Series of the Riley Elf was installed, although in a modified Cooper trim with a second SU carburettor and higher compression. The engine generated 55 b.h.p. at 5800 r.p.m. The torque was higher and applied earlier, and this meant that the new model had greater traction and was rather faster for the same power.
