Ahead of an official unveiling at the Geneva motor show on 6 March, Chevrolet offers this tantalising glimpse of the 2014 Corvette Stingray Convertible.

The droptop Stingray wears a three-ply fabric top with sound-absorbing padding and a glass rear window. The top is fully automatic – no header latch to unfasten by hand – and it can be opened or closed at speeds up to 30mph or, in a clever touch, remotely, using the key fob. Beneath its carbon-fibre and sheet-moulded composite skin, the open-air ‘Vette makes use of the closed car’s stiff, lightweight aluminium structure; the company is insistent that the convertible will preserve the coupe’s driving dynamics. “We designed and developed the coupe and convertible simultaneously,” says Ed Welburn, vice president of global design at General Motors. “As a result, the Corvette Stingray offers an open-top driving experience with no compromise in performance, technology or design.”

Providing the motivation is Chevrolet’s new LT1 6.2-litre V8. As it does in the Stingray coupe, the engine produces some 450 horsepower and 450 pound-feet of torque. Performance figures are forthcoming, but Chevrolet insists that both cars will move from a stop to 60mph in less than four seconds. The Z51 Performance Package adds a close-ratio gearset, an electronic limited-slip differential, a dry-sump oiling system and coolers for the brakes, transmission and differential – features intended to cope with the demands of track use.

Coupe and convertible arrive in North American showrooms late this year, at prices to be announced closer to their sale dates. Chevrolet also plans to introduce what has come to be known as America’s Sports Car to Continental Europe, Britain, the Middle East, Japan and Russia.
