We already know that Mercedes-Benz is planning several variants of its next-generation A-Class and recently revealed B-Class, five in fact, and most of these will likely be sold in the U.S.

What we don’t know is just what five variants will be launched.

So far we know there will be the B-Class MPV, A-Class Hatchback, and BLS-Class four-door coupe, but the shape of the remaining two variants remains a mystery.

Most suggest they will be a BLK compact crossover and new A-Class roadster, but the guys at Auto Express are reporting that instead of a roadster Mercedes is likely to launch a more conventional convertible model.

This makes sense as a cabriolet, Mercedes’ preferred name for its convertibles, based on the new A-Class would serve as the ideal rival for the likes of the A3 Cabriolet and BMW 1-Series Convertible.

Like the new A-Class, on which it will be based, drive will go to the front wheels via a seven-speed dual clutch transmission. A six-speed manual, however, should remain as an option in certain markets.

If we’re lucky, there could also be a high-performance AMG variant packing a 320 horsepower turbocharged four-cylinder engine and standard all-wheel drive system.

Sadly, if the reports prove true, sales of an A-Class Cabriolet aren’t likely to start until around 2014 at the earliest.
