AC Ace

The all new AC Ace arrived in 1953, designed by talented AC engineer John Tojeiro. The Ace used the old 1991cc AC engine which it shared with the ageing 2 Litre model, although performance was still reasonable.

The cars distinctive body was produced in aluminium and looked similar to contemporary Ferrari models, it would also form the basis for the legendary Cobra in years to come.

Some enthusiasts still believe that the Ace was always a better car than the Cobra. It was met with mixed acclaim and probably there were other cars on the market at that time.
