Spy Shots: Mercedes-Benz SLS AMG Roadster

We've been all but assured that a convertible version of the 2011 Mercedes-Benz SLS AMG was on the way, and now we've got photographic proof of the de-gullwinged drop-top weathering the wintery climes before its reveal in 2010.

Although Mercedes officials haven't divulged much about the SLS cabrio, it's likely to be fitted with a retractable soft-top rather than a folding hard-top in a bid to keep weight in check and retain some of the trunk's capacity. Naturally, the chassis will be fortified to increase rigidity, but considering the SLS AMG was designed from the onset to be both a coupe and a convertible, we suspect the extent of the modifications to be limited and the weight penalty to be minimal.

Some reports indicate that the SLS AMG Roadster could debut as early as the Geneva Motor Show in March, but if we were betting gentlemen, we'd suspect the convertible SLS to debut later in 2010, likely at the Paris Motor Show.
