Pictures claimed to be of the next-generation Chevolet Corvette Stingray convertible have appeared days after the coupe premiered at the Detroit motor show.

The unofficial pictures show that, with the hood down, the only visible differences between the bodystyles is that the cabrio loses the full width rear spoiler, and it appears to have smaller wheels.

The flush rear desk suggests the convertible will use a fabric roof, as the current Corvette C6 does, rather than a bulky and heavy folding hard top.

There should be few engineering challenges in transforming the coupe into a drop-top as the car premiered at the Detroit show featured a removeable targa top. Images of the car's chassis show that the roof is not integral to the Corvette's structure, although the bracing around the rear of the roof would need to be removed.

The Corvette cabriolet is expected to go on sale next year, with production beginning next spring.
