The partnership between Mercedes and McLaren for the SLR supercar is drawing to a close, but there is still at least one new model in the works. A speedster version of the SLR 722 Edition is expected to be released in time for the Paris Motor Show this October, but until then this video of the standard hardtop 722 Edition serves to sharpen anticipation for the new topless model.

The '722' moniker is derived from the start time of Sir Sterling Moss's record-setting 1955 Mille Miglia run - 7:22 a.m.
