2007 Mercedes-Benz SLR 722 Edition

The new Mercedes-Benz SLR 722 Edition has all the attributes of a thoroughbred racing car. Refined in numerous respects, this super sports car has more output, a tailor-made suspension configuration and a decidedly sporty interior. Sale of the SLR 722 Edition in the U.S. has not been confirmed.

Continuing the Tradition

The new model variant SLR 722 Edition is a homage by Mercedes-Benz to the unforgettable victory won by the British racing legend Stirling Moss and his co-driver Denis Jenkinson in a Mercedes-Benz 300 SLR with the starting number 722 (indicating a start time of 7.22 a.m.) at the Mille Miglia in 1955. With an output of 650 bhp and a corresponding performance, the new super sports car, which goes on sale on July 11, 2006, will not only make the hearts of car enthusiasts beat faster.

The supercharged 5.5-liter V8 engine in the 722 Edition, which is hand-built in the AMG engine shop in Affalterbach, generates 650 bhp. The particular strengths of this high-performance engine are immediate response to movements of the accelerator, highly emphatic torque build-up and an unmistakable V8 sound. The performance figures are outstanding even for a high-end sports car: the 722 Edition accelerates from standstill to 62 mph in only 3.6 seconds, and 124 mph is reached in just 10.2 seconds. The top speed (209 mph) is above the 207 mph previously achieved by the SLR.

Handling characteristics worthy of the racetrack are also provided by the sophisticated suspension, with 19-inch light-alloy wheels, a stiffer damper configuration and 0.4 inches lower body. Larger brake discs with a diameter of 390 mm ensure excellent braking performance.

Discreet visual modifications mark the Mercedes-Benz SLR 722 Edition out as special, in line with the wishes of the enthusiastic gentleman drivers and wealthy sports car collectors who make up the core target group. The modified front spoiler with an air splitter, as well as the rear diffuser, improve both the aerodynamics and contact pressure at high speeds, and reflect the transfer of cutting-edge technology from motor racing. At the same time, the use of clear-lacquered carbon as an extremely strong yet lightweight material symbolizes the practicality of these technical features. Bucket-type sports seats upholstered in leather/Alcantara provide outstanding lateral support, while the grippier racing steering wheel with a hunting-leather lining, gearshift paddles and black carbon highlights lend a thoroughbred racing touch to the interior.

The supercharged 5.5-litre V8 engine in the 722 Edition, which is hand-built in the AMG engine shop in Affalterbach, generates 478 kW/650 hp. The particular strengths of this high-performance engine are immediate response to movements of the accelerator, highly emphatic torque build-up and an unmistakable V8 sound. The performance figures are outstanding even for a high-end sports car: the 722 Edition accelerates from standstill to 100 km/h in only 3.6 seconds, and 200 km/h is reached in just 10.2 seconds. The maximum speed (337 km/h) is above the 334 km/h previously achieved by the SLR.

Handling characteristics worthy of the racetrack are also provided by the sophisticated suspension, with 19-inch light-alloy wheels, a stiffer damper configuration and a ten-millimetre-lower body. Larger brake discs with a diameter of 390 mm ensure excellent braking performance.

The technological and aesthetic improvements are all well and good, but is the 722 Edition a better driving machine than the SLR that came before? In a word, yes. It's lighter and more aerodynamic, and the revised throttle curve and quicker torque delivery make it leap from the line as though it were setting out on a qualifying lap.

It's also more expensive. Pricing hasn't been finalized, but it's expected to cost somewhere between the current SLR's $452,000 and a half-million bucks when it goes on sale this summer.

Even if you've got the requisite wad, there's no guarantee an SLR 772 Edition will end up in your stable. McLaren's F1 works in Woking, England, will build only 150 examples, largely by hand, and how many 722s will come to America is unclear.
