The Brabus Rocket 900 Cabrio Is A 900-HP Luxury Mercedes S65 Monster

This is the fastest four-seat convertible in the world.

Following in the footsteps of its coupe counterpart, Brabus has just lifted the lid on its latest creation just in time for the Frankfurt Motor Show. Based on the Mercedes-AMG S65, the Brabus Rocket 900 Cabrio packs the same twin-turbo V12 albeit one that’s been bored out from 6.0 to 6.3 liters in order to extract 900 horsepower and 1,106 lb-ft of torque (limited to 885 lb-ft). The 12-cylinder unit gets a special billet-steel crankshaft with longer stroke, matching forged pistons for the enlarged cylinder bores and precision-balanced conrods.

Special exhaust mainfolds with turbochargers that boast a larger compressor unit and turbine replace the stock turbos, while larger downpipes and a high-performance exhaust with actively-controlled exhaust flaps have also been fitted. Brabus says the V12’s sound can be changed from Dr. Jekyll to Mr. Hyde (or ‘Coming Home’ to ‘Sport’) via a button on the steering wheel. To provide the engine with more air, a bespoke intake module draws air directly from the radiator grille via an air duct in the hood. A special air filter box with larger intake cross-section and special filters is included in the new set up, while Gold Heat Reflection sheathing for the intake pipes helps keep the temperature lower for enhanced performance.

Other mods include a remapped ECU and a Stop/Start Memory system. Power is sent to the rear wheels via a bespoke seven-speed automatic transmission and high-performance limited-slip differential with a 40 percent locking rate. Drivers can shift the gears manually via new aluminum steering wheel mounted paddle shifters. With a 0-62 mph time of 3.9 seconds and top speed in excess of 217 mph, the Brabus Rocket 900 Cabrio is the fastest, most powerful open-top four-seater on the planet. New aerodynamic components developed in the wind tunnel and made with a naked carbon finish include a race-inspired front spoiler, diffuser, and rear spoiler, while tailor-made carbon surrounds the air intakes and door mirrors.

Completing the exterior treatment is a lowering module that drops the open-top 2+2 by 15 mm, and a set of alloys ranging from 18 to 22 inches. When the car makes its debut in Frankfurt, it will be wearing a set of 21-inch Platinum Edition wheels painted in Shadow Grey. As always, Brabus upgrades the interior to customer’s exact specifications. On the show car, fine leather finished in Mondial Vanilla and Mondial Black has been used, with decorative stitching and black and red topstitching. Black ash wood with an open-pore finish has also been used, while other unique touches include aluminum pedals and door pins, scuff plates with a backlit Brabus logo, and a Brabus speedometer that goes all the way to 250 mph.
