A real sleeper.  The Brabus CL600 features a tire smoking 730 HP Twin-Turbo V12 allowing for a top speed of 211 MPH and 0-60MPH of under 4 seconds.  A sport-tuned suspension and high power breaking system keep all that speed in check while subtle aerodynamic enhancements and lightweight 21 inch alloys give the hint that something special is underneath the hood.
