Brabus 700 Biturbo - Click above for high-res image gallery

It's become quite clear that Mansory and Fab Design should leave SLS-tuning to the experts. Brabus has pulled back the wraps on its 700 Biturbo, and the results are pants-tightening impressive.

Brabus has taken the 6.2-liter SLS AMG V8 and attached a pair of turbochargers to the already-excellent mill. Output has gone from 563 horsepower and 479 pound-feet of torque, up to 700-hp and 626 lb-ft of torque. Brabus has also gone ahead and changed the intake and exhaust manifolds, engine mapping and exhaust system on the Mercedes-Benz flagship.

In fact, Brabus has gotten down to the nitty-gritty with its 700 Biturbo at the Geneva Motor Show. Traditionally, twin-turbocharged engines have a pair of turbos both spinning in the same direction. Brabus has fitted a right-turning and left-turning exhaust to the respective sides of the engine, and this allows for optimal air flow into the engine.

All of this work has produced a luxurious grand tourer that hits 0-62 miles per hour in 3.7 seconds, and can run on to top speed of 213 mph. Brabus has managed to do all of this without slapping on eye-searing paint an ill-advised body kit (though obviously there's an extensive bit of aero-tweakery present), and for that, we thank them. (Next time, though, maybe we can find someone around to close the hood...)

World Debut at the Geneva Motor Show 2011
BRABUS 700 Biturbo Based on the Mercedes SLS AMG
700 hp / 514 kW, 850 Nm and 340 km/h Top Speed

BRABUS 700 Biturbo: Powered by the new BRABUS twin-turbo engine with 700 hp (690 bhp) / 514 kW and a peak torque of 850 Nm (626 lb-ft) and clad in the thrilling WIDESTAR wide-body version the Mercedes SLS AMG from BRABUS ascends to a new level in the league of super sports cars. The gullwing, further refined by an exclusive interior, reaches a top speed of 340 km/h (213 mph) and celebrates its world debut at the Geneva Motor Show 2011.

A high-tech turbocharger system for the high-tech engine of the SLS: The BRABUS engine engineers have designed a state-of-the-art twin turbo system for the fast-revving eightcylinder four-valve engine of the SLS.

The high-performance exhaust manifolds are optimized for exhaust-gas flow and were custom-developed for this sports car. They drive the two turbochargers. The chargers themselves are another BRABUS custom development. For faster response and better efficiency both chargers feature an air diverter valve.

V-engines are normally fitted with two right-turning chargers, which entails drawbacks for the
response characteristics. To eliminate these drawbacks the BRABUS engineers have developed the B63 bi-turbo system with a left-turning charger for the left side of the engine. That allows the turbine and its inlet to be designed for perfect gas flow and gas dynamics. The result is an outstanding engine with an exemplary power curve.

The BRABUS engine conversion also includes a generously dimensioned intercooling system with two water-to-air heat exchangers. The dual-flow intake manifold gets its combustion air through a package-optimized air filter housing and high-performance air filters.The company engine shop also modifies the inner workings of the engine that like all BRABUS engines is lubricated exclusively with fully-synthetic ARAL high-performance motor oil.

Specially manufactured BRABUS forged pistons reduce the compression ratio to 9.0:1. The newly programmed engine management system with special mapping for ignition and injection orchestrates the perfect interaction of the BRABUS high-performance components.

The system also features an integrated electronic boost pressure control. The result is an engine that delivers its extreme power smoothly while meeting the strict emission limits set by EURO V standards.

The exhaust side of the V8-engine is upgraded with free-flow high-performance catalysts and
the BRABUS high-performance exhaust system that features four slanted tailpipes with diameters of 84 millimeters (3.2 in.). The BRABUS exhaust is made from ultra-light titanium and weighs 12 kilograms (26 lbs.) less than the production exhaust. A pneumatic flap system, controlled from the cockpit, adds a "coming home"sound setting that is quieter than the production exhaust. The alternatively selectable sport setting gives the 6.3-liter eight cylinder engine an even throatier note than the stock exhaust.

Powered by this engine the BRABUS 700 Biturbo is among the most powerful super sports cars in the world. As the name indicates, the engine produces a rated power output of 700 hp
(690 bhp) / 514 kW at 6,600 rpm. The peak torque of 850 Nm (626 lb-ft) is already available at a low 4,300 rpm.

In combination with the SPEEDSHIFT DCT seven-speed sport transmission the resulting performance is breathtaking: The two-seater car sprints from rest to 100 km/h (62 mph) in just 3.7 seconds and reaches 200 km/h (124 mph) in 10.2 seconds. Top speed is 340 km/h (213 mph).

To give the SLS also a sportier appearance the BRABUS WIDESTAR wide-body version was developed in the wind tunnel. Like in Formula 1 racing all aerodynamic-enhancement components are manufactured from lightweight yet high-strength carbon-fiber compounds. The body components can be painted in body or contrasting color or finished with a clear coat for a purebred racing look.

The BRABUS WIDESTAR flares on the rear axle add 20 millimeters (0.8 in.) to the width of the gullwing. They also facilitate the installation of ultra-light forged wheels, which widen the track and thus further improve driving dynamics. To put even more emphasis on the wedge shape of the coupe the BRABUS Monoblock F "PLATINUM EDITION"wheels are mounted in a staggered combination of size 9.5Jx20 wheels in front and size 11Jx21 on the rear axle.

Despite the fact that the wheels are larger than their production counterparts they weigh up
to 12 percent less. The wheels are either ceramics-polished or come with a brushed-design surface. They can also be painted any desired color. The high-performance tires in sizes 275/30 ZR 20 and 295/25 ZR 21 are supplied by BRABUS technology partners Pirelli and YOKOHAMA.

At the high speeds attained by the BRABUS 700 Biturbo aerodynamic stability is absolutely essential. The BRABUS front spoiler reduces lift on the front axle at high speed. Combined with the two BRABUS covers for the upper air inlets in the apron it lends the SLS an even more striking face.

For optimal aerodynamic balance BRABUS upgrades the rear with a spoiler lip on the trunk lid and a diffuser. Additionally the rear apron is fitted with side air outlets. The sides of the gullwing are upgraded by the BRABUS gills for the front fenders. At night their integrated, blue-illuminated BRABUS lettering, activated by the keyless fob or by pulling
on a door handle, stands out immediately.

Sporty yet elegant side skirts create a perfect aerodynamic transition between front and rear
fenders. The cladding features integrated entrance lights for safe entering and exiting of the
vehicle in the dark.

The BRABUS suspension was developed in cooperation with technology partner BILSTEIN. It offers advantages both visual and driving dynamics benefits. Those include a ride-height lowering by up to 30 millimeters (1.2 in.). The integrated 'Ride Control'function offers the driver a choice between more comfortable or sportier damper settings compared to the production car, all at the push of a button in the cockpit.BRABUS sport stabilizers on front and rear axle affect even more agile turn-in ability and further reduced body roll.

The BRABUS Ride Control smooth-ride suspension is also available with the optional BRABUS Front Lift system. BRABUS Front Lift can raise the front axle by 50 mm (2.0 in.) and increases the approach angle.

Custom-tailored interiors have been a special BRABUS domain for more than three decades. The company upholstery shop crafts individual, masterful exclusive interiors in any desired leather or Alcantara color for the SLS as well.

These interiors are complemented by an ergonomically shaped sport steering wheel, a speedometer with 400-km/h (250-mph) dial and matte or shiny carbon-fiber elements in any desired color. Matte anodized aluminum pedals and foot rest add further distinctly sporty highlights.

      I don't like the look of this car. Looks flat out ugly. Perhaps a new set of shoes would make this car look better, at least for me.
      • 3 Years Ago
      wonder how long until Mercedes offers to buy Brabus and merge them with its AMG division. I think the resulting cars would be insane.
      • 3 Years Ago
      I see lots of tack-on Pepboys accessories on this.
      • 3 Years Ago
      So...its no faster than a regular SLS to 60. Amazing how it takes 137 more horsepower to go 13mph faster
      • 3 Years Ago
      I have to say that the SLS is starting to grow on me. The basic shape is quite nice, it's just the headlights that don't match the rest of the car.

      Anyway. I usually like Brabus's work and this is no exception. They seem to make a car that's the same, but with more of what you want.
        • 3 Years Ago
        Agree, except for the HUGE "B" on the front and the quilted stitching on the seats. Otherwise this looks amazing.
      • 3 Years Ago
      almost every tuner has made this car better in every aspect that MB didn't do to start with ......IMO everybody
