The BMW E63 M6

Possibly the fastest BMW ever made is the E63 M6.
This " Velvet Hammer"can hit 0 to 60 in about 4.6 seconds.
This land rocket has a speed limiter that keeps it at 155 mph.
BUT, with the limiter removed, the M6 can hit around 205 mph.
With the cool little "power button" the BMW jumps from 399 hp to a full 500 hp!
