1956 the AC Aceca became available with the 2 litre Bristol
engine also used in the open AC Ace model. The Aceca made good use of the
extra power afforded by the 1971cc Bristol six cylinder.
1957 front disc brakes became standard equipment (again,
these were available on the open Ace), an overdrive gearbox could also be
fitted and became a popular option. The Aceca-Bristol remained in
1963, by which time 169 cars had been built. The car was
constructed with an aluminium body to a high standard. Rather sadly, the
rear suspension could tuck in during hard cornering.
