Time marches on and the F10 BMW M5 continues its cold weather testing ahead of its scheduled launch for 2011. To recap, this car is expected to utilize a turbo charged V8 engine derived from the motor used in the X5 and X6 M. Power outputs are still unknown but I would bet on it being higher then that of the X5/X6M. Other M5 Spy pictures can be seen here.
