1955 AC Aceca
British manufacturer AC introduced the Aceca fastback coupe in 1954 as a more refined companion to their successful Ace roadster. The lightweight aluminum-bodied sports car shared the ladder-framed chassis and most steering and running gear with its open-top sibling, but offered greater comfort and practicality for road use.
The Aceca initially used AC’s own 2.0-liter overhead-camshaft six-cylinder engine, a design dating back to 1919 that produced around 85 horsepower, later increased to about 102 horsepower. While this vintage powerplant provided adequate performance, it was long past its development potential and considered underpowered for the sophisticated chassis.
The fastback body featured longer, timber-framed doors and a steel tube-supported roof. Inside, the Aceca offered more luxury than the Ace with full leather upholstery, Wilton carpets, and varnished timber trim. A fiberglass bulkhead reduced cabin noise and heat, while the rear storage area was accessible through a hinged trunk lid, similar to contemporary Aston Martins.
With only around 328 examples produced, the Aceca remains relatively obscure compared to its roadster counterpart, which would eventually evolve into the famous Shelby Cobra.
