speed auto, RWD
The 2009 Mercedes-Benz SLR McLaren Roadster 722 S is a limited
edition (150 will be produced) model which delivers 650 hp (478
kW), acceleration from 0 to 62 mph in 3.7 seconds, and a maximum
speed of 208 mph (335 km/h). Both the 722 S Roadster and the
Mclaren SLR Roadster feature a fully retractable carbon
fiber folding soft top capable of withstanding high speeds.
This endows both models with a very high degree of safety and
extreme torsional stiffness. In addition to increased power,
the new SLR McLaren Roadster 722 S features even more dynamic
suspension tuning and improved aerodynamics.
By naming this new model variant the SLR Roadster 722 S, Mercedes-Benz
is recalling the historic victory won at the classic Mille Miglia
long-distance race in 1955 by British motor-racing legend Stirling
Moss and his co-driver Dennis Jenkinson, in a Mercedes-Benz
300 SLR with the starting number 722.
Powering the SLR Roadster 722 S is a supercharged 5.5-litre
V8 engine which is hand-built in the Mercedes-AMG engine shop
in Affalterbach. With an output of 650 hp and 820 Nm of torque
the 722 S Roadster can meet the demands of the most discerning
drivers, with a high level of performance combined with excellent
The five-speed automatic transmission developed by Mercedes-Benz
is designed for high performance. It is specially configured
for a very high torque, and allows the driver to choose between
two sets of shift characteristics.
The spring and shock absorber configurations of the 722 S Roadster
are stiffer, and the body has been lowered by 10 millimetres
at the front and rear. This helps increases the handling stability
of the Mercedes-Benz SLR McLaren Roadster 722 S. The lightweight,
19-inch forged aluminium wheels allow a view of the red-painted
brake callipers on the heat-resistant carbon-fibre/ceramic brake
The soft top opens and closes semi-automatically in around ten
seconds, combining comfort expectations with the purist nature
of the roadster. For opening, the roof needs to be unlatched
at the windscreen frame and lifted slightly, after which it
folds down electrically. The front section of the soft top features
an integral aluminium cap, which effectively prevents "ballooning"
at high speeds.
The handling and aerodynamics of the SLR 722 S Roadster were
optimised for high speeds in the wind tunnel. The aerodynamic
concept follows that of the SLR
Coupé, with an airbrake integrated into the boot lid, an
enclosed underbody and a diffusor in the rear bumper to ensure
the greatest possible downforce on the rear axle. The so-called
airsplitter at the front end augments this downforce, while
small wheel spoilers reduce turbulence at the rear axle.
A high level of safety is provided by unique carbon-fibre crash
structures, steel-reinforced A-pillars and two fixed rollover
bars. Other safety features include adaptive airbags, knee and
sidebags, belt tensioners and a tyre pressure monitoring system.
Inside, the Mercedes Mclaren SLR 722 Roadster features sports
bucket seats upholstered in a combination of semi-aniline leather/Alcantara.
Striking visual highlights are provided by the contrasting seams
in 300 SL red, the embossed 722 S lettering on the head restraints
and the likewise red seat belts. Frequently used controls such
as the shift and parking brake levers are lined in particularly
high-grip and moisture-absorbing suede leather. Generous use
of carbon-fibre underlines the high-performance philosophy and
adds a particularly puristic touch.
The Mercedes Mclaren SLR 722 S Roadster features two-zone automatic
climate control, a high-quality BOSE Premium sound system, a
multifunction sports steering wheel with shift paddles and a
navigation system with an integrated radio and CD player.
