Another Brabus record breaker. The Brabus SV12 S Biturbo Roadster was the most powerful drop-top on the planet when it arrived in 2006.

Like other bespoke Brabus cars, it had to be restrained, such was extent of the modifications. A 730bhp twin-turbo V12 engine - 213bhp more than the factory Mercedes-Benz model -  and an electronically limited top speed of 217 mph tells you all you need to know.
