The end result is an extremely impressive set of performance figures, even by high-end super sports car standards: the SLR 722 Edition completes the sprint from 0 to 100 km/h in a breathtaking 3.6 seconds (SLR 3.8 seconds), going on to achieve 200 km/h in just 10.2 seconds (standard McLaren SLR 10.6 seconds) and 300 km/h in a mere 28.0 seconds (SLR 28.8 seconds). Plus the top speed of 337 km/h is even higher than that of the current SLR (334 km/h).
One of the main driving forces behind the further improved performance of the SLR 722 Edition is the retuned chassis. Development work at McLaren's Formula-1 headquarters was based on the SLR's proven aluminium chassis set-up. In the first phase of development, various chassis parameters, such as springing and damping, underwent a series of tests on the Formula-1 dynamometer in Woking. Then the Mercedes-Benz and McLaren engineers made further refinements and finalised the new set-up by performing an extensive series of tests on the road and, above all, on the race track. The stiffer spring rates and shock-absorber characteristics of the chassis (body lowered by 10 mm at both the front and rear) are what gives the SLR 722 Edition its increased directional stability and noticeably further enhanced handling dynamics. Body roll on bends has been reduced by over 20 percent, allowing the new SLR 722 Edition to corner at even greater speeds.
New 19-inch forged-aluminium wheels also improve the handling dynamics of the special-edition model, their unique, palladium grey design highlighting the car's motor-racing heritage. Their low weight, compared to ordinary tires, reduces the unsprung masses, making the SLR 722 Edition even more responsive. Plus the 19-inch wheels allow larger brake discs with a diameter of 390 mm to be fitted on the front axle. Hailing from the Italian manufacturer “Brembo”, the new braking system combines with the carbon fibre-reinforced ceramic discs to provide a highly impressive deceleration rate which is fully in keeping with the SLR 722 Edition's scintillating all-round performance. Extensive tests were carried out to develop a new ESP® control system for this new brake configuration.
Around 100 hours of meticulous work in the wind tunnel also helped boost the performance of the SLR 722 Edition. Here the developers performed yet another technical masterstroke by increasing downforce whilst at the same time reducing the Cd (drag coefficient) figure. At higher speeds, lower aerodynamic drag generally means lower downforce.Not so in the case of the SLR 722 Edition though, which has an "airsplitter" at its front end. Consisting of carbon with a clear-coat finish, the distinctively shaped spoiler lip not only enhances aerodynamics, it also increases the downforce on the front axle by 128 percent. Small wheel spoilers, also finished in carbon, reduce air swirl at the rear axle, making for smoother airflow and optimising road feel. If the 13-percent increase in rear-end downforce is also added into the equation, the new SLR 722 Edition provides 122 kg total downforce. In the 35° high-downforce position of the airbrake, the total downforce is increased by another 50 kg. The result: an even more reliable handling and more precise turn-in at high speeds.
In addition, the rear-mounted airbrake optimises directional stability and braking power. When the speed exceeds 120 km/h, it rises up at an angle that has been adjusted in line with the extremely dynamic performance of the new model. If the driver hits the brakes hard in an emergency, the airbrake is automatically raised. This dynamic modification increases rear-axle downforce within a fraction of a second, thus partially compensating for the dynamic axle load distribution during braking, which has a tendency to press towards the front axle.
A further factor which contributes to the distinctly sports-oriented configuration is the weight of the SLR 722 Edition, which the engineers have reduced by around 44 kg. A lighter oil tank and damper bodies made from aluminium, which have the added benefit of improving the vibration response of the unsprung masses, make for less weight. Furthermore, various parts and components have been replaced by carbon, including in the footwell and at the rear wheel arches. Last but not least, optimised panelling and insulating materials also have a positive effect on the vehicle weight. Yet for all these measures, the high levels of comfort, safety and practicality that have become Mercedes hallmarks remain unaffected.
The complete performance package at the heart of the SLR 722 Edition really comes into its own when matched with a sporty driving style. This is when the true benefits of the improved cornering ability, the higher lateral acceleration and the even more agile handling really make themselves felt.
