Mercedes-Benz have been kind enough to let Roger Federer loose in a brand new SLS AMG Roadster. The Swiss tennis legend put the open-top model through its paces across the deserts of Dubai, in what is actually not a bad promo. With almost identical performance to its tin-topped sibling, the Roadster hits 60 mph in just 3.7 seconds, before topping out at (an electronically governed) 197 mph. Production begins in the fall of 2011.
