Mercedes-Benz SLR McLaren 722 Edition

Overview
Text orignally from the SLR's Wikipedia article 

The Mercedes-Benz SLR McLaren is a grand tourer car manufactured by Mercedes-Benz. Unveiled as the Vision SLR Concept in 1999, the car was later put into production between 2003 and 2009. The SLR is powered by a 5.4 liter V8 equipped with a supercharger producing 0.9 bar of boost. The hand-built AMG engine is positioned behind the front axle and delivers 626 horsepower at 6,500rpm. The maximum torque of 780Nm is available from 3,250rpm and remains at this level up to 5,000rpm. The front-mid engine is paired with a five-speed automatic transmission which transfers the power to the rear wheels.

A new version was introduced in 2006, called the Mercedes-Benz SLR McLaren 722 Edition. The "722" refers to the victory by 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.

The 722 Edition includes an engine rated 650 PS (480 kW; 640 hp) at 6,500 rpm and 820 N·m (600 lb·ft) at 4,000 rpm. 19-inch light-alloy wheels were used to reduce unsprung weight, while modifications were also made to the suspension, with a stiffer damper setup and 10 mm (0.39 in) lower ride height introduced for improved handling. Larger 390 mm (15 in) diameter front brakes and a revised front air dam and rear diffuser were fitted.

A roadster version of the SLR went on sale in September 2007. It uses the same supercharged V8 AMG power plant as its coupé siblings, developing 626 PS (460 kW; 617 hp), to propel it to a top speed of 334 km/h (208 mph) and a 0 to 100 km/h (62 mph) acceleration time of 3.7 seconds.
