BMW’s M division has been chronicling the development of the new 2012 M5 by a series of online teaser videos. So after seeing the car in snow, or drifting on a track, or just driving along on mountains roads, now check out some footage of it doing highspeed tests at Nardò Ring in the south of Italy, one of the few places on earth where you can actually max high performance cars. Now this video gets us thinking, is there a possibility the new M5 won’t be limited to 250 km/h? We certainly like to think so!
