This 2006 BMW M6 is an awe-inspiring machine. Once your MDrive preferences are set, press the “M” button on the steering wheel, position your hands at the paddle shifters, and let ‘er rip. If you’re feeling real good about the absence of traffic enforcement within the immediate vicinity, engage Launch Control while you’re at it. Either way, the M6 howls like a racecar and flies down the road, gathering speed so rapidly you barely know you’re into triple-digit territory because there’s no indication that the muscular V-10 is anywhere close to thinking about quitting time.
