The Mercedes-Benz S63 AMG coupe is now even more potent, thanks to German tuning company Brabus. The Brabus 850 6.0 Biturbo Coupe, headed to the 2015 Geneva auto show, packs an 850-hp punch, 848 lb-ft of torque, and a claimed top speed of 217 mph.
To extract that power from a regular Mercedes-Benz S63 AMG coupe, Brabus begins by boring and stroking the 5.5-liter twin-turbo V-8 to displace 5.9 liters. Two new, larger turbochargers are fitted, along with a new Brabus exhaust system, a larger intake that sucks air through a hood vent, and new engine-computer programming. In the standard car, the 5.5-liter twin-turbo V-8 engine produces 577 hp and 665 lb-ft, giving the S63 AMG coupe a limited top speed of 186 mph.
Given the speeds Brabus claims the 850 6.0 Biturbo can reach, the tuning company gave the Mercedes-Benz S63 AMG coupe several new aerodynamic parts that were tested in a wind tunnel. A carbon-fiber rear diffuser and trunk spoiler, as well as carbon-fiber grille surrounds on the front air intakes, are all said to improve the car’s high-speed performance.
The modified Mercedes rides on new Brabus wheels ranging from 18 to 22 inches in diameter, depending on the customer’s desire, but Brabus recommends its 21-inch forged “Platinum Edition” wheels shod in sticky tiers for maximum performance. The car’s air suspension is reprogrammed to ride 0.6 inch lower than a standard Mercedes-Benz S63 AMG coupe.
Finally, the Brabus 850 6.0 Biturbo receives visual tweaks in the cabin, including new glossy carbon-fiber trim pieces, new aluminum shift paddles, special leather upholstery, and a black Alcantara headliner.
For buyers who want their super-fast Mercedes-Benz with four doors, Brabus also offers the 850 6.0 Biturbo treatment for the E63 AMG sedan. That version offers only 838 hp but is still said to be able to hit 217 mph.
