Brabus is sending a Mercedes-AMG C63 S Cabriolet to Geneva image

With 650 hp on tap you can go full throttle and even reach the magical milestone of 200 mph (320 km/h) – just don’t do it on the Geneva show floor.

There are mere hours from seeing all the latest and greatest vehicles during the 2017 Geneva Motor Show, so aftermarket specialists are rushing to join the crop of carmakers and present their own projects. For example, well known Mercedes specialist Brabus has decided to introduce a convertible just in time for the open season – based on the already mean and nimble C63 S. Of course, the heart and soul of this project is the meaty aftermarket package sitting under the hood – AMG’s biturbo V8 4.0-liter engine has been massaged from the standard 510 hp (375 kW) to a massive 650 hp (478 kW), while torque has been taken from 700 Nm (516 lb-ft) to a huge 820 Nm (604 lb-ft).

With all that added oomph, the C63 S Cabriolet will sprint from 0 to 62 mph (100 kph) in a mere 3.7 seconds, which is 0.4s faster than before. Go for the Autobahn or the test track and you’ll be able to hit the sweetspot – 200 mph (320 kph) thanks to the reworked electronic speed controller. Brabus has even changed the speedometer to display up to 211 mph (340 kph). Design changes include carbon fiber parts that were aerodynamically optimized in the wind tunnel.
