Why it matters

The Aceca-Bristol is the closed coupe companion to the Ace-Bristol, offering more refinement and sound insulation. With the Bristol six it won its class at Sebring in 1958 and 1959 and at Le Mans in 1959.

History

AC debuted the Aceca at the 1954 London Motor Show as a more refined coupe variant of the Ace. In 1956 the optional 1,971 cc Bristol six raised advertised power from 90 to 105 hp, or 125 hp in D2 tune. Catalogues count 328 Aceca coupes built between 1954 and 1963, across all engine types.
