Background
The success of independent racing car builder Cliff Davis' Tojeiro sports-racer prompted AC Cars to put the design into production in 1954 as the Ace.
The Davis car's pretty Ferrari 166-inspired barchetta bodywork was retained, as was John Tojeiro's twin-tube ladder frame chassis and Cooper-influenced all-independent suspension, while the power unit was initially AC's own venerable, 2.0-litre, long-stroke six.
This overhead-camshaft engine originated in 1919 and with a modest 80bhp (later 100bhp) on tap, endowed the Ace with respectable, if not outstanding, performance.
A hardtop version - the fastback-styled Aceca coupé - debuted at the Earls Court Motor Show in 1954.
The first prototype Aceca belonged to no less a legend than Donald Campbell, who retro-fitted a Bristol engine to it.
The Aceca's hatchback body was constructed in hand-formed aluminium over a tubular steel framework, while the tubular chassis was more substantially built than the Ace's.
To reduce noise levels within the cabin, AC mounted all major components on rubber bushes. The result was a well-engineered, lightweight and extremely pretty GT car in the best AC tradition.
