In partnership with Motul and their subsidiary Startech, Brabus took to the 24 hours of Le Mans this year to introduce their latest overpowered Mercedes. The new Brabus Mercedes S63 Cabriolet 850 comes to us as the world’s fastest four-seat cabrio with a top speed of 350 km/h.

That serious turns of speed is, obviously, the result of 850 rampaging stallions the tuner has managed to squeeze out of the V8 motor under the bonnet. Brabus Mercedes S63 Cabriolet 850 started life as a 4MATIC S63 with a 5.5 liter bi-turbo engine and 585 horsepower, but it now has a 6.0 liter Brabus V8 with different turbos, inlet and outlet manifolds, exhaust, intake, and software.

As a result the car now has the possession of 850 horsepower and a colossal 1,450 Nm of torque. That gives the car a top speed of 350 km/h (217 mph), and although they haven’t mentioned the 0 to 100 km/h sprint time, it must be pretty damn good thanks to the all-wheel-drive system. Naturally, this Brabus uses Motul lubricants, as the stickers on it so clearly suggest.

Besides the power upgrade Brabus Mercedes S63 Cabriolet 850 also comes with the firm’s unique carbon fiber aero kit for this model – consisting of carbon front bumper attachments and spoiler, front grille, side skirts, front wings, rear diffuser with tailpipes and boot lid spoiler – as well as a set of 21 inch Monoblock wheels. Brakes and suspension are also enhanced accordingly, and you can order a bespoke interior as well.
