RML
reveals the new Mercedes-Benz
SLR McLaren 722 GT
After
months of secret development, RML has released details of
the stunning Mercedes-Benz SLR McLaren 722 GT - a new supersportscar
for the racetrack.
Following repeated requests from motor racing enthusiasts
among the SLR.CLUB membership, the British motor racing
specialists RML Group (Ray Mallock Ltd) has developed the
new SLR 722 GT. This
puristic super-sportscar is designed exclusively for the
racetrack and has no approval for on-road use but will take
part in the SLR.CLUB Trophy, a competition series forming
part of the SLR. CLUB racetrack programme in Europe.
Compared
to the production version (left) the SLR 722 GT has been
uniquely and comprehensively re-engineered by RML, with
particular emphasis on the suspension, braking system, aerodynamics,
interior and exhaust system. More than 400 components were
redesigned. The key data for this edition limited to 21
two-seaters includes a kerb weight 1390 kilograms, a maximum
power output 500 kW/680 ps at 1.75 bar boost, and a maximum
torque of 830 Newton metres - all guaranteed to provide
maximum racetrack performance.
The SLR 722 GT already makes a powerful impression at standstill:
new body components such as the front apron with front splitter,
wide wings, prominent side skirts, the large rear diffuser
and the fixed rear spoiler are obvious indicators of outstanding
racetrack performance and extensive aerodynamic development
work.
Similarly, the redesigned bonnet hints at the supercharged
AMG 5.5-litre V8-engine that lies beneath - uprated by RML
to develop a peak output of 500 kW/680 ps and a maximum
torque of 830 Newton metres. A racing air filter and a new
exhaust system ensure outstanding responsiveness and an
even more striking engine sound. Dispensing with numerous
comfort features means that the SLR 722 GT tips the scales
at a kerb weight of just 1390 kilograms. The result is a
favourable power-to-weight ratio of 2.0 kg/ps and an acceleration
time of 3.3 seconds from standstill to 100 km/h. The maximum
speed is 315 km/h (196 mph).
Modified suspension with central wheel locks
Fast lap times are guaranteed by the newly developed suspension:
a new wheel location system at both front and rear provides
improved kinematics and lateral dynamics. A modified stabiliser
at the front axle reduces roll when cornering, while an
adjustable wheel camber combined with shock absorbers with
variable compression and rebound characteristics allow the
suspension to be set up for different racetracks. 18-inch
lightalloy wheels with central locks allow fast tyre-changes
during a race – which is also assisted by the pneumatic
jacking system.
Power
is transferred by a five-speed automatic transmission with
steering wheel shift paddles, which has been adapted to
suit racing conditions. A mechanical locking differential
with a locking effect of 70 percent under acceleration and
80 percent on the overrun ensures traction without loss
of power. Highly efficient, fade resistant
braking is provided by the new racing brakes complying with
FIA GT regulations, which feature a modified cooling airflow
and adjustable balance. The interior of the SLR 722 GT is
characterised by the functional atmosphere of a thoroughbred
racing car. Details include a rollover cage, a redesigned
instrument panel with a racing display, a racing steering
wheel and bucket seats with six-point seat belts.
Developed by motor racing specialists
Development,
production and sales of the SLR 722 GT are in the hands
of the renowned British motorsport and automotive specialists
RML Group. A maximum of 21 vehicles will be produced. Servicing
and participation in racing events is also under the aegis
of RML in collaboration with the SLR.SAFETY & SPEED
ACADEMY.
The owners of cars already ordered are all members of the
SLR.CLUB – a highly exclusive community which organises
events relating to the SLR (right) and is chaired by Dr.
Dieter Zetsche, Chairman of Daimler AG and CEO of Mercedes-Benz
Cars. The SLR.SAFETY & SPEED ACADEMY forming part of
the SLR.CLUB offers special driver training courses, and
enables customers to acquire a national Category A racing
licence. Prominent, highly-skilled instructors for the SLR.CLUB
include David Coulthard, Klaus Ludwig, Jochen Mass, Chris
Goodwin and Christina Surer. The central focus of SLR.CLUB
events is on automotive passion, professionalism and perfection.
The
cost of one of the cars is reputed to be in the region of
775,000 Euros.
