1954→1963 AC Aceca-Bristol

Introduced in 1954, the Aceca was a fastback version of AC’s seminal Ace roadster. Built as an exclusive Grand Touring car, each Aceca featured new curved windshield and a hinged rear hatch.

Like the Ace, the Aceca had the same sporting independent suspension and lightweight aluminum body that made the car popular. Half way into production, the antiquated prewar AC engine was replaced by a Bristol unit having 120 bhp.

About 300 Acecas were completed before both it and the Ace were replaced by the potent AC Cobra.
