When Mercedes-Benz unveiled the convertible version of its very rare SLR McLaren 722 S Coupe late last month, all it had for us were ethereal renderings of what the car would look like. This week the German automaker has given unto us a gallery's worth of high-res photography showing what is likely to become the world's fastest convertible. The SLR McLaren Roadster 722 S features the same 650-hp supercharged 5.5L V8 as the coupe version, but lops off its top in favor of a power soft top that can actually sustain 200+mph speeds. The only other convertible we can think of that could possibly compete is the recently spied 602-hp Bentley Continental GTC Speed, the coupe version of which can crest 200 mph. Hmm... we're getting a good idea for a comparison test. Excuse us while we make a few calls.
