The Biturbo Cabrio is billed as the fastest and most powerful four-seat convertible in the world.Mercedes-Benz tuner Brabus has introduced a hot-rodded version of the Mercedes-AMG S63 Cabriolet.Presented during the 24 Hours of Le Mans, the Brabus 850 6.0 Biturbo Cabrio is billed as the fastest and most powerful four-seat convertible in the world. Helping Brabus make that claim is a 6.0-liter V8 engine fitted with a special crankshaft, matching forged pistons, high-performance connecting rods, and re-machined cylinder heads.
The eight-cylinder is fed by a pair of Brabus-specific turbochargers. All told, it makes 850 horsepower at 5,400 rpm and a jaw-dropping 1,069 pound-feet of torque between 2,500 to 4,500 rpm. However, Brabus points out the engine's torque output is limited to 848 pound-feet for the sake of longevity.
Power is sent to all four wheels via a seven-speed automatic transmission with shift paddles and AMG's 4Matic all-wheel drive system. The Biturbo Cabrio hits 60 mph from a stop in 3.5 seconds, 124 mph from a stop in 9.4 seconds, and it goes on to a top speed of 217 mph.
Visually, Brabus has added a new front bumper with a splitter, a trunk-mounted spoiler, a carbon fiber air diffuser, and 21-inch forged wheels. In other words, it retains a discreet, wolf-in-sheep's-clothing appearance. Customers can choose to keep the stock interior, or to have it customized with add-ons such as illuminated sill plates and carbon fiber trim.
