RML Press Release:
The new Mercedes-Benz SLR McLaren 722 GT – a puristic super-sportscar for the racetrack
Following repeated requests by motor racing enthusiasts among the SLR. CLUB members, the British motor racing specialists RML Group (Ray Mallock Ltd) have developed the new SLR 722 GT. This puristic super-sportscar is designed exclusively for the racetrack, has no approval for on-road use and will take part in the SLR. CLUB Trophy, a competition series forming part of the SLR. CLUB racetrack programme in Europe.
Compared to the series-production version, the SLR 722 GT has been uniquely and comprehensively
re-engineered by RML, especially with respect to the suspension, braking system, aerodynamics, interior and exhaust system. More than 400 components were redesigned. The key data of this edition limited to 21 two-seaters – kerb weight 1390 kilograms, maximum output 500 kW/680 ps at 1.75 bar boost,and maximum torque of 830 Newton metres to guarantee 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.
The likewise redesigned bonnet conceals a supercharged AMG 5.5-litre V8-engine uprated by RML to develop a peak output of 500 kW/680 psand 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.
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 light-alloy 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 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. Eye-catching 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.
