Brabus has built some of the wildest Mercedes in the world, but I think it’s lost its freaking mind with its new, hair-plug-ripping Brabus 850 6.0 Biturbo Cabrio. It also goes by the cute name of the world’s fastest and most powerful four-seat cabriolet ever built…
This rig is based on the Mercedes-AMG S63 Cabriolet, which is badass enough on its own with its 5.5-liter biturbo V-8 that pounds out 577 horsepower and a 3.8-second sprint to 60 mph. But, that’s not good enough for the crazy folks at Brabus. Instead, they bored the engine out to 6 liters, added new con rods and pistons, strapped on a pair of new compressors, installed some new fuel and air intake bits, and cranked the wick of this engine up to a wild 838 horsepower and 1,069 pound-feet of torque. To help keep the powertrain, which includes 4MATIC all-wheel drive and a seven-speed dual clutch gearbox, from imploding, Brabus opted to limit the torque electronically to 848 pound-feet.
All of this power dumps out through a Brabus sport exhaust system with ceramic tips. This system uses butterfly valves that open up on the wide-open road for a supercar-like howl while a “Come Home” mode quiets everything down a bit.
Handling is taken care of by Brabus Platinum Edition 21-inch wheels wrapped in Yokohama tires sized 225/35R21 up front and 295/30R21 out back, and Brabus’ lowering module that drops the S63’s ride height by 0.6 inches. Optionally, buyers can add 22-inch wheels.
All told, this big coupe will sprint to lunge to 62 mph in just 3.5 seconds (approximately 3.3 seconds to 60 mph) and top out at an electronically limited 217 mph due to tire limitations.
With this crazy speed, Brabus had to craft some aero goodies to keep the S63 from taking flight, so it created a slew of downforce-enhancing add-ons from naked carbon fiber with a high-gloss finish. These components include a front spoiler, a rear spoiler, and a rear diffuser. For visual effect, there the same carbon makes up the mirror caps and the air inlet surrounds.
Brabus didn’t reveal pricing for this upgrade, but I think “expensive” covers it nicely.
