The AC Aceca, produced from 1954 to 1963, was a closed grand touring coupé built by AC Cars in Britain, effectively serving as the fixed-roof counterpart to the AC Ace roadster that underpinned it. The first generation launched with AC's own engine before expanding to include the Aceca-Bristol variant from 1956, which used a Bristol unit and became the more popular choice among buyers seeking stronger performance. A small number of later cars received a 2553cc Ford Zephyr engine and were marketed as the Aceca 2.6, broadening the powertrain options across the model's nine-year run. With a top speed of 250 km/h and a weight of 1615 kg, the Aceca established the template for the enclosed AC sports car that would later inform the Aceca Brooklands.
