A brief history
|
1961
- Carroll Shelby, a Texan ex-race driver, entered
negotiations with AC Cars and with the backing of The Ford Motor
Company, proposed the installation of a large Ford vee eight engine in
the current lightweight AC Ace. Built by AC Cars, the combination
resulted in the AC Cobra, one of the fastest and most brutal sports cars
ever produced.
2001 - AC Car Group Centenary and the new AC Coupé is announced. AC move to Frimley in Surrey After
a lawsuit with Ford and Shelby, Ford got the Cobra name and used in its
sporty version of Mustang. AC continues building the variants of Cobra
but no longer uses the name. |
Famous Cars
The original Cobra was developed from the Ace, launched in 1953. The Ace was itself developed from a racer designed by John Tojeiro (later, to give his endorsement to the British DAX Cobra replica). It featured independent suspension by transverse leaf springs, Bristol power and Ferrari inspired bodywork. The body style changed on the production Ace and power was by AC's alloy 1,991cc , ohc , six; a well-known unit originally designed by AC's founder, John Weller, in the 192Os.
Bristol's remarkable BMW derived 1,971cc, l25bhp+ six became an option in 1956; the engine powered the Ace to many race victories around the world, including in SCCA events in the US where it won Class E championships three years running. Ken Rudd narrowly missed out on two British championships in his own Ace Bristol.
Bristol ceased engine production in 1959, leaving AC looking round for a new engine and stopping the gap in the meantime with Ford power in the shape of the Zephyr 2.6- litre, a lifeless and rougher unit.
The Ace-Bristol had been noticed by retiring race driver Carroll Shelby, who approached AC and Ford in 1961 with the idea of combining the AC chassis with Ford's new lightweight 260ci, 164bhp V8. Production of the first aluminum-bodied Cobras, with strengthened Ace chassis and drive train, began in 1962. Engine size went up to 289ci in 1963 with the MkII - still leaf sprung, mind, but with rack and pinion steering. That year a Cobra took seventh place at Le Mans. It was 1964 before AC started selling right hand drive customer cars, the rest having gone for export. In 1965, the year the Cobra finally took the FIA World Championship for Ford for the first time ever, the 425bhp, 427 (7-litre) Cobra MkIII was announced a car capable of accelerating from 0 to 100 mph and stopping again all in under 14 seconds! For the 427 the chassis was strengthened and at last gained coil springs. Customer, as opposed to race specification, 427s mostly came with the softer, heavier 428 engine but the exceptions were the 425bhp 427S/Cs, the schoolboy's wet-dream variant with side pipes, fat rear guards, bonnet scoop and oil cooler vent being the main distinguishing features.
Cobra 427 production stopped after Ford withdrew factory support from Shelby's racing programme in 1965, although AC kept building the ' AC 289 ' until 1968 using the 427 chassis with the 289 engine and wire wheels - and Cobras kept winning races well into the 1970s.

A-98: -
AC planned it after the reasonable success of their 'fastback' 1963 Le Mans entries, as their entry for Le Mans 1964. In spite of the odd chassis number, it was based on a normal 289 leaf-spring chassis. but in this case with a coupe body styled by AC's Alan Turner. Like the Miles Daytona it used the body to make the original chassis a good bit stiffer and it was also longer arid lower. Its nose was not unlike a GT4O's, and its rear quarters not dissimilar to a Ferrari GTO but, its most distinctive feature was small Mercedes style eyebrows over each wheel arch. designed to separate the airflow over upper and lower body sections.
HEM-6: -
AC built this right hand drive leaf spring Cobra for racing in Europe in 1964. It was built to full FIA spec's. It was sold to Tommy Atkins less engine and gearbox, then raced by Roy Salvadori at the 1964 British Grand Prix. third place was gained in the GT class. Later it was raced in numerous events and then registered for rad use.

AC-428: -
The Frua bodied(styled by Frua in Italy) AC 428 which was built on a lengthened coil spring 427 chassis(6 in's), did not last long; started in 1967; 58 coupes and 28 convertibles where made , finally production stopped in 1973.
CSX5001-CSX5002: -
The Ghia's, these where commissioned by shelby in 1965 CSX5001 and CSX5002 now both are 427's, but originally one was a roadster and the other had a removable hard top, the interiors where very stylish and had a lot more comfort options than the Cobra; wind up windows!, unveiled at the turin show in 1966.
Infamous Cars
AC made the Cobra but have you ever seen a real one!
If you are over 30 you have probably seen lots of AC's but never realised
Remember those little blue invalid carriages that were foisted on to disabled people? Try racing one of those!
