The Centaur was built by Concept Cars Ltd. in Northampton from 1973, being sold between 1974 and 1977.
The design was heavily based on a styling exercise of the Adams brothers, the Probe. In fact, they passed their project on to Peter Timpson of Concept Cars, who marketed their idea made more practical.
In 1970, Timpson had acquired the second Probe 15 bodyshell and modified it considerably. He widened it and height went up to 37". The major change was a pair of perspex windows which doubled up as doors. Imp basis remained, and body was a tough GRP-and-plywood monocoque with box section and steel tube reinforcement. A high quality construction.
It was a rear engined two seater sports car with full integral roll structure. Large flat windscreen in laminated safety glass. Luggage space behind seats. Front boot. Petrol tank. Perspex sidescreens give wide angle vision, and hinged at front leadign edge to give access to car interior. Removable rear deck for easy engine accessibility. Lather covered aluminium steering wheel. Instruments and switches fitted. Gearstick and handbrake between seats. Fully upholstered and carpeted. Wiring loom, hydraulic pipes, wipers and washers all fited. Quartz halogen headlamps with sidelamps, front and rear indicators, stop/side tail lamps. Finished in your own choice of any manufacturers colour. Heater and ventilator. All other components excluding engine/transaxle, suspension, radiator, battery, wheels and tyres.
Some 52 cars were sold, at the most.
A 1978 2+2 version of the Centaur GT. It had a midmounted Leyland Maxi 2.2 engine, and a complex multi-tubular chassis (designed by Frank Costin) with de-dion rear suspension lay-out. The glass fibre bodywork (design and construction: Peter Timpson) made its family relation to the Centaur very evident.
The Mk2 has been described as safe and very affordable.
