Mercedes Benz SLR McLaren Roadster 722S

The heart of the SLR Roadster 722 S – an AMG V8 5.5 - litre supercharged

engine – propels the car with all the verve one would expect from an output

of 478 kW / 650 hp. In order to keep this formidable power safely under control,

the SLR Roadster 722 S is equipped with numerous innovative features. Among

the most noticeable – both visually and because of the way they enhance the

ride quality – are the distinctive 19 - inch wheels painted in palladium grey.

Off ering the perfect combination of low weight and high rigidity, they reduce

unsprung masses and improve the vehicle’s damping characteristics. 

Many aspects of the SLR Roadster 722 S make it as special as its legendary

predecessor. The soft top, for example : woven from black and anthracite yarn,

the fabric changes colour depending on the angle of the light. The in tegrated

composite panel prevents the soft top from ballooning at high speeds and

reduces wind noise to a minimum. Thanks to optimised aerodynamics, the

soft - top SLR Roadster 722 S attains Cd values almost on a par with those of

the SLR Coupé. The hand - sewn fabric is positioned on the frame assembly with

pin - point accuracy. With the roof folded you can enjoy all the positive aspects

of open - top driving without being buff eted by the wind or compromising on

safety. This is made possible by a 10 - cm - high wind defl ector which eliminates

air turbulence in the car, and the carbon - fi bre monocoque with a reinforced

high - strength A-pillar. Off ering the highest degree of safety, the monocoque

provides the level of stiff ness called for by the vehicle’s driving dynamics.

Thanks to the excellent aerodynamics, the only thing that can be heard in the

cockpit – even when the soft top is open – is the sound that in spires every

SLR driver : the stirring note of the supercharged V8 engine.

Concealed beneath the skin of the SLR Roadster 722 S is a wealth of Formula 1

safety technology. The occupants benefi t from the all - round protection of

a carbon - fi bre monocoque – an innovation from the world of motorsport which

makes the SLR Roadster 722 S one of the safest roadsters in its class. But it

also sets standards for interior design : covered in black semi - aniline leather

and Alcantara, its seats are pleasantly comfortable while providing a high

degree of lateral support. Interior appointments on the vehicle controls are

covered in fi ne suede and off er the driver a secure grip in every situation.
