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 program 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 3064 lbs, maximum output 680 bhp at 1.75 bar boost, and maximum torque of 612 lb-ft to guarantee maximum racetrack performance.
The likewise redesigned bonnet conceals a supercharged AMG 5.5-liter V8-engine uprated by RML to develop a peak output of 680 bhp and a maximum torque of 612 lb-ft. 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 3064 lbs. The result is a favorable power-to-weight ratio and an acceleration time of 3.3 seconds from standstill to 100 km/h. The maximum speed is 195 mph.
