BMW's shown us the new 2012 M5, and we've even already had some drive time on an icy Swedish lake, but now we can hear the new über-sedan in full twin-turbo wail.

With 557 hp and 502 lb-ft of torque routing through a seven-speed, dual clutch paddle tranny, the new M5 can carry you to 60 mph in a few ticks over 4 seconds, and if he or she speaks the magic words, the speed limiter will be raised from 150 mph to 190 mph for track time fun. BMW should sell this car's engine note as a ringtone.
