Designed by John Tojeiro on a ladder type tubular frame transverse leaf spring suspension, and an open two-seater alloy body made using English wheeling machines and possibly inspired by the Ferrari 166 MM. The AC was launched in 1953, early cars were powered by the venerable AC 100bhp two-litre overhead cam straight-six engine that had first been introduced at the end of WW1, but was still good for a 103mph top speed and a 0-60mph time of 11.4 seconds. It was hardly a sporting engine however, and it was decided a more modern engine was required.
In 1954 the Ace, soft top was joined by the Aceca hard top coupé, which had an early form of hatchback rear door but used the same basic timber framed alloy body.
From 1956, there was the option of Bristol Cars' two-litre 120 bhp (89 kW) straight-six with 3 downdraught carburettors and slick four-speed gearbox. Top speed leapt to 116 mph and the 0-60 mph sprint time was down to around nine seconds.. Overdrive was available from 1956 and front disc brakes were an option from 1957, although they were later standardised.
In 1961 a new 2.6-litre (2,553 cc) straight six Ruddspeed engine option was offered adapted by Ken Rudd from the unit used in the Ford Zephyr. It used three Weber or SU carburettors and either a Mays or cast iron head. Boosting tuned versions to 170bhp providing a top speed of 130 mph However, it was not long before Carroll Shelby drew AC's attention to the Cobra, so only 37 of the 2.6 models were made
