Track Tested: 2009 Mercedes-Benz CLS63 AMG
This is the car that started the whole "four-door coupe" thing. Seemed like a strange idea at the time, but now the Mercedes-Benz CLS is the old-timer of the low-roof sedan crowd.
Still looks good though, and when you stuff AMG's 6.2-liter V8 under its hood the CLS feels good too. The standard CLS550 is no slouch, but the AMG setup turns the CLS into the low-slung street sleeper that its design has always promised. Just look at these numbers and see for yourself.

Acceleration Comments: Monster torque and instant throttle response means "pedaling" this beast is a must off the line. Traction control does almost as well without any of the careful footwork.
Braking Comments: Solid and consistent pedal response - impressive for a large sedan, but typical of AMG.
Handling Comments: (Skidpad) Easy to balance on the throttle. Good balance and response for such a large sedan. (Slalom) Best slalom run w/suspension in softest setting, otherwise it was too stiff and easily upset.
