After the presentation of the new 850 6,0 Biturbo Cabrio on the sidelines of the 24h of Le Mans 2016, Brabus has dropped additional photos and details on their Mercedes-AMG S63-based convertible.

The Germans have made a name for themselves by turning new Mercedes-Benz models into mega-horsepower super stars and with the 850 6.0 Biturbo Cabrio, they claim to have created the world’s most powerful and fastest four-seater convertible.

To claim that title, Brabus took the stock Mercedes-AMG S63 Convertible and dialed its 5.5-liter twin-turbo V8 up to eleven, increasing displacement to 6.0-liters and either replacing or thoroughly revising many engine components and peripherals, from the high-performance connecting rods and turbochargers with larger compressor units, to the modified exhaust manifolds and ECU.

These upgrades result in an increase of 261hp and 550Nm (406 lb-ft) of peak torque, from 577hp (585PS) and 900Nm (664 lb-ft) to 838hp (850PS) and 1,450 Nm (1,069 lb-ft) respectively. All that power is transferred to the road by the 4MATIC all-wheel-drive system and a seven-speed automatic transmission with paddle shifters allowing for a sprint from zero to 100km/h (62mph) in 3.5 seconds – a 0.4 sec improvement over the factory S63, and to 200km/h (124mph) in 9.4 seconds. Top speed is restricted to 350 km/h (217 mph), not because the 850 can’t go faster, but because of tire limitations.

Brabus fits the 850 6.0 Biturbo Cabrio with a suspension module that can lower the ride height up to 15mm or 0.6 inches and which is specifically calibrated for the use of ultra-low-profile tires size 255/35 ZR 21 at the front and 295/30 ZR 21 on the rear axle, or optionally, 22-inch rims on 255/30 ZR 22 tires front and 295/25 ZR 22 rear.

Along with the lowered stance and bigger rims and wider tires, Brabus developed a carbon fiber aerodynamic kit comprising of a front spoiler and intake surrounds, rear diffuser, boot lid spoiler and mirror caps. For the interior, the German tuner offers a bevy of options, ranging from scuff plates with backlit BRABUS logo and genuine carbon and aluminum trims, to a custom speedometer and a full upholstery makeover.

The 850 6.0 Biturbo Cabrio can be ordered as complete new car or by upgrading an existing S63 AMG Convertible, with Brabus backing the tune with three-year or 100,000-kilometer/62,000-mile warranty, whichever comes first.
