German tuner fits its own twin-turbo system to the SLS AMG for an output of 700 PS (514 kW / 690 bhp) and 850 Nm (626 lb-ft) of torque.

The Brabus 700 Biturbo, based on the Mercedes-Benz SLS AMG, has hit the floor at the Geneva auto show today.

Engineers at the German tuner have devised their own twin-turbo system to fit to the SLS's V8 engine to achieve an output of 700 PS (514 kW / 690 bhp) and 850 Nm (626 lb-ft) of torque. The B63 bi-turbo system features a left-turning charger attached to the left side of the engine, as opposed to most right-charging, right-side fitted twin-turbochargers. This type of fitting allows for improved gas flow and dynamics.

Brabus also provides an intercooling system, performance exhaust manifold, sport air filter system, does an ECU remap and fits its own forged pistons that reduce the compression ratio to 9.0:1.

The new performance exhaust system is also a Brabus in-house creation made of ultra-light titanium and features four slanted tailpipes 84 mm in diameter.

Final performance figures: 0 to 100 km/h (62 mph) is 3.7 seconds, 200 km/h (124 mph) is reached in 10.2 seconds and top speed is 340 km/h (213 mph).

A wide-body kit (WIDESTAR) is fitted that widens the SLS at the rear axle by 20 mm. There's also a front spoiler, rear spoiler lip on the trunk lid and a rear diffuser. Gills are fitted to the front fender with blue-illuminated Brabus lettering.

Wheels are Brabus's own 9.5J x 20-inch rims, with 275/30 ZR 20 tires, for the front axle, and 11J x 21-inchers wrapped in 295/25 ZR 21 tires at the back. Tires are supplied by Pirelli or Yokohama.

A Bilstein suspension kit lowers the SLS by 30 mm while Brabus sport stabilizers are added to the front and rear axles for improved stability.

On the inside is a new sport steering wheel, a 400 km/h (250 mph) speedometer, matte or shining carbon-fiber trims in a variety of colors, as well as matte anodized aluminum pedals and foot rest.
