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

of 7:22 a.m.) at the Mille Miglia in 1955.
The “722 Edition” includes an engine rated 650 PS (480 kW; 640 hp)@6500rpm and 820
N·m (600 lb·ft)@4000rpm, with top speed of 337 km/h (209 mph) (3 km/h (1.9 mph) faster
than the standard SLR). 19-inch light-alloy wheels were used to reduce unsprung weight,

taillights and headlamps.
The SLR 722 can go from 0 to 100 km/h (62 mph) in 3.6 seconds, 200 km/h (120 mph)
in 10.2 seconds and 300 km/h (190 mph) in 29.6 seconds and can reach a top speed
