You've already seen the 2012 BMW M5 on track, but this latest video features some great fly-bys, launches, and track footage--this time without the operatic score drowning out the squealing tires and throaty exhaust.

That's reason enough for us to spend some quality time with the new Bimmer super sedan, but if you need more justification, consider the 2012 M5's prodigious 560-horsepower output and 502 pound-feet of torque generated by the twin-turbo V-8, and what it might sound like. Yep.
