Alongside a 700-horsepower (515-kilowatt) E63 sedan, Brabus introduced an equally stunning, even more powerful new S65 Cabriolet at the Frankfurt Motor Show. The aptly named S65 Rocket 900 is said to be the world’s fastest, most powerful four-seat convertible – and it comes with the performance credentials to back it up.
Under the hood is the same biturbo V12 that comes from the factory, but Brabus has bored it out to 6.3-liters instead of the standard 6.0-liters. A whopping 267 additional horsepower (200 kilowatt) has been added, bringing the total horsepower figure to 888 (662 kW), and torque up from 738 pound-feet (1,000 Newton-meters), to 1,106 pound-feet (1,500 Newton-meters) at 4,200 rpm. Due to reliability concerns, that latter figure is electronically limited to 885 lb-ft (1,200 Nm).

All that power is routed through a seven-speed automatic transmission that Brabus has modified slightly to handle the added oomph. A custom limited-slip differential, a completely new intake manifold, bigger down pipes, and a high-performance exhaust (with active flaps) has been added to the package.
With all the available upgrades in tow, the Brabus S65 Rocket can, well, rocket to 62 mph (100 kmh) in just 3.9 seconds, making it two-tenths of a second quicker than the standard S65 Cabrio. Top speed is electronically limited to 155 mph (250 kmh), or 186 mph (300 kmh) with the optional driver’s pack. With all the governors removed, this S65 will reportedly top out at 217 mph (350 kmh).
Along with all the over-the-top performance upgrades, Brabus has made sure to include an equally extravagant interior to go along with it. A new digital speedometer, aluminum accents, LED ambient lighting, and illuminated Brabus logos can be seen throughout he cabin. The vehicle on display in Frankfurt comes with a two-tone Mondial Vanilla and Mondial Black leather, with a jet black exterior finish.
