2011 BMW M5 testing at the Nurburgring – Click above to watch video after the jump

The 2011 BMW M5 has been caught on video doing its thing around the 'Ring, and by "doing its thing" we really mean shredding the life out of the rear tires. Judging from the quick video, the massive sedan seems to have no problem hustling through the banked curves of every automaker's favorite test track.

BMW has kept its lips sealed when it comes to what exactly is under the hood of the next-generation M5 or when the lowly public will be able to get their greedy paws on the finished product. Rumor has it the German automaker has ditched the big, naturally-aspirated V10 we all know and love in favor of the same twin-turbocharged V8 found at the heart of X5 M and X6 M. If true, that means the car is packing somewhere around 578 horsepower in its arsenal.

As for when we'll finally see this big beastie without its psychedelic camouflage, your guess is as good as ours. In the mean time, hit the jump to see the uber sedan tackle the 'Ring.
