The Mercedes SLS AMG ascends to a new level in the league of super
sports cars with the new Brabus twin-turbo engine with 690 hp (700 PS) and
Widestar body kit. The gullwing, further refined by an exclusive interior, reaches a top
speed of 213 mph (340 km/h) and celebrates its world debut at the Geneva Motor
Show 2011.
High-Tech Turbocharger System
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 PS (that's
690 hp) at 6,600 rpm. The peak torque of 626 lb-ft (850 Nm) is already
available at a low 4,300 rpm.
The defining factor in this modification is
the state-of-the-art twin turbo
system. 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.
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.
Brabus High-Performance Exhaust
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 26 lbs (12 kilograms) 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.
Seven-Speed
Transmission
In combination with the SPEEDSHIFT DCT
seven-speed sport transmission the resulting performance is breathtaking. The
two-seater car sprints from rest to 60 mph in just 3.6 seconds and
reaches 124 mph (200 km/h) in 10.2 seconds. Top speed is 213 mph (340 km/h).
Widestar Wide Body
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 0.8 in. (20 milimeters)
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 ZR20 and 295/25ZR 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.
Bilstein
Suspension
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 1.2 inches (30 millimeters). 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
2.0 in. (50 mm) and increases the approach angle.
Custom Interior
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 250-mph (400-km/h) dial and matte or shiny carbon-fiber elements in any
desired color. Matte anodized aluminum pedals and foot rest add further
distinctly sporty highlights.
