Description

The SLR 722's supercharged V-8 is reprogrammed, getting an extra 24 horsepower and 30 pound-feet of torque. It also gets bigger (15.4 inch) carbon front brakes, lighter wheels, aluminum shocks with 20-percent-stiffer damping, and a higher-downforce carbon-fiber front splitter paired with more angle on the movable rear spoiler. All told, these changes, along with less carpeting and sound deadening, shave a claimed 97 pounds from the SLR's not insubstantial mass.

Mercedes also claims these changes increase top speed from 207 to 209 mph and cut the 0-to-62-mph sprint from 3.8 seconds to 3.6.

The SLR 722 Edition is an homage to the Mercedes-Benz 300SLR that carried British Grand Prix driver Stirling Moss and journalist/navigator Denis Jenkinson to victory in the 1955 Mille Miglia road race. The number "722" refers to their start time-7:22 a.m. (after departing Brescia, the pair completed a 1000-mile loop through Italy in a record-setting 10 hours, 7 minutes, and 48 seconds-an average speed of almost 98 mph).

The 722 has it, all right. As noted, the supercharged and intercooled, 5.4-liter V-8-each one handmade at the AMG works in Affalterbach, Germany, before being shipped off to the McLaren assembly facility in Woking, England-has been bumped to 641 horsepower at 6500 rpm and 605 pound-feet of torque (up from the regular SLR's 575) at 4000. As before, the engine mates to a five-speed automatic transmission, now with aluminum shift paddles (for manual-mode gear selection) instead of wheel-mounted buttons. The retuned chassis is stiffer and almost a half inch lower, the forged-aluminum wheels have grown to 19-inches all around, the front brakes (Brembo carbon-ceramic discs) have swelled to 15.4 inches, and the bodywork features a new carbon-fiber front splitter that increases downforce on the front axle by 128 percent-without increasing drag. In addition, overall weight is down by nearly 100 pounds, thanks to lighter wheels, aluminum shock housings, and thinner carpeting. Inside, the cockpit sports new leather trim (including a spectacular Alcantara steering wheel), red stitching, and lavish expanses of carbon fiber.
