2011 Geneva Motor Show: Brabus 700 Biturbo based on Mercedes-Benz SLS AMG

Article by Christian A., on March 3, 2011

The German aftermarket developer Brabus has displayed its modification job on a Mercedes-Benz SLS at the Geneva Motor Show. Dubbed the Brabus 700 Biturbo, the vehicle delivers 700hp at 6,600 rpm and 850 Nm (626 lb-ft) available from 4,300 rpm. The 6.2-liter V8 engine doesn’t have its “natural aspiration” status anymore.

Instead it is equipped with Brabus’ B63 biturbo system, which uses a left-turning charger for the left side of the powerplant.

The unit also features a water-to-air intercooler and upgraded internals. To enable the vehicle to handle this much power, it has a custom suspension that it developed together with Bilstein. The car has also been given 20-inch lightweight alloy rims.

The car is able to accelerate from a standstill to 62 mph in 3.7 seconds and on to 124 mph (200 km/h) in 10.2 seconds. It has a top speed of 213 mph (340 km/h).

The supercar has been given a Widestar widebody kit that includes multiple carbon fiber components. These are finished in either body or contrasting color or they can be given a clear coat.

Exterior Design

To make sure that the SLS had a sportier look, its wide-body Brabus WIDESTAR variant used the wind tunnel as part of its development. Similar to many Formula 1 racing cars, all of the components that help improve aerodynamics have been made using carbon-fiber compounds, a material that has high strength but is lightweight.

When it comes to the body components, there is the choice to paint it in body color or a contrasting color but the finish is in a clear coat giving it a purebred racing appearance. Flares have been added to its rear axle to help it increase the width of its gullwing by as much as 20 mm (0.8 in).

The flares also aid in installing the forged ultra-light wheels that widen the track and therefore enhance the driving dynamics. In terms of wheels, mounted to the Brabus Monoblock F "PLATINUM EDITION" are ones that are sized 9.5Jx20 for the front axle with the ones on the rear axle sized at 11Jx21. The reason for this staggered combination is that it highlights the coupe’s wedge shape. Still despite the wheels being larger, they weigh 12% less compared to the wheels in the production version.

The wheels come in either a brushed design surface or a ceramic polish but can be painted with the preferred color. Its high-performance tires are supplied by Pirelli and YOKOHAMA, Brabus’s technology partners.

The tires come in two sizes: 295/25 ZR 21 and 275/30 ZR 20. When running at high speeds, it is important to have the Brabus 700 Biturbo aerodynamic stability. An example of this is the Brabus front spoiler which helps lower the lift on its front axle. When combined with the two covers of the upper air inlets placed on its air inlet, the SLS gets that striking face.

In order to attain that optimum aerodynamic balance, Brabus upgraded the rear portion by putting in a diffuser and placing a spoiler lip on its trunk lid. The rear apron has also been equipped with the side air outlets. Even the sides of the gullwing have been upgraded by Brabus with gills for the front fenders.

Standing out during the night time is the integrated Brabus lettering that has been blue-illuminated which can be activated by either pulling on the door handle or using a keyless fob. The side skirts are elegant but sporty which helps achieve that flawless aerodynamic transition from the front fender to the rear ones. Integrated to the cladding features are the entrance lights that allow one to safely enter and exit this vehicle even at night.

Interior Design

The tailoring of its interior has been customized, a Brabus specialty spanning more than 30 years. It is the company’s own upholstery shop that crafts the exclusive and unique interiors that can come in either desired leather or even the Alcantara color.

Complementing the features on the interior is the sport steering wheel that has been ergonomically shaped. Then there is the speedometer that has a 400-km/h (250 mph) dial. The carbon-fiber elements are shiny or in matte and comes with the desired color. Offering more unique sporty highlights are the Matte anodized aluminum pedals and its foot rest.

Brabus 700 Biturbo

Brabus 700 Biturbo is 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 2011 Geneva Motor Show.

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 eight-cylinder 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.
