The Mercedes-Benz SLR McLaren 722 Edition was introduced in 2006 with the same V8 engine as the previous model albeit modified for an increase in horse power and torque. Other changes included 19-inch alloy wheels used to reduce unsprung weight, a 10mm lower ride height, a stiffer damper set up, larger 15 inch diameter front brakes, a revised front air dam and a fitted rear diffuser. The 722 name 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.
