Background
In stark contrast to the later Carroll Shelby AC Cobra, the original AC Ace of 1953 was a delicate, understated little thing. Fitted with an elderly straight-six engine, the car’s 100bhp gave it a top speed of 103mph and an acceleration time of around eleven and a half seconds to 60mph. It was sprightly, but nothing more.
Until, that is, British racing driver Ken Rudd (yes, the AC history appears to be littered with racing drivers sticking their noses in…) built the very first Ace with a two-litre Bristol engine in it, a 20bhp leap in power that slashed around two and a half seconds off the 0-60mph time and added 13mph to the top speed. The modification so impressed the factory that it adopted it itself in 1956.
The Bristol engine wasn’t only more powerful than the AC engine, it also responded to tuning much better, something that the Ace’s sweet chassis was able to exploit to giant-killing effect on the track. So a new 2.6 litre Ford Zephyr engine was made available, a straight-six developed by Rudds, from 1961. Using triple Weber or SU carburettors and either a ‘Mays’ or a cast-iron head, up to 170bhp was available, giving a potential top speed of 130mph alongside a 0-60mph time of just over eight seconds.
However, Carroll Shelby’s effective-but-brutal V8-powered cars had drawn the factory’s attention by now, leading it to neglect the six-cylinder cars. Production ended in 1963 after just 37 examples of the 2.6-litre Aces had been built.
This means that original examples now command a hefty price, something that has encouraged dozens of kit car manufacturers to build replicas, some of which even look similar to the factory cars.
Hawk, on the other hand, has built an enviable reputation over the past two decades and builds beautifully engineered AC-inspired cars that are widely acknowledged as being the best in the business.
Gerry Hawkridge, the founder, is also so widely acknowledged as a pre-eminent AC guru that his firm usually has a genuine Ace or Cobra onsite for maintenance.
Oh, and because everyone goes for the mighty AC Cobra when they’re buying a Hawk, we’re told that the Ace you see here is actually rarer than the car it is based upon…
