Making the swap from a naturally aspirated 6.3- 6.2-liter V8 to a direct injection, twin-turbo 5.5-liter V8 hasn't at all reduced the Mercedes CL63 AMG's brawny beauty. The standard version gets 544 horsepower and 590 pound-feet of torque. Opt for the AMG Performance Package and you boost that to 571 hp and 664 lb-ft. All that power doesn't come with a bigger fuel price, either: at 22 combined miles per gallon with the help of stop/start and the AMG Speedshift MCT seven-speed sport transmission, the new car posts a 25 percent increase in fuel economy over the 6.2-liter beast.
The AMG Performance Package that throws in all that extra gumption also comes with double-spoke wheels in titanium gray, extra carbon fiber trim under the hood and in the cabin, as well as a leather and Alcantara steering wheel. With it you get a 4.4-second 0-60 time, without you'll have to make do with 4.5 seconds.
Helping you keep things composed while on the move are crosswind stabilization added to the Active Body Control, Direct Steer and Torque Vectoring Braking, which brakes the inside wheel when necessary to maintain crispness when things go curvy. If you're looking for a bit of green, you'll find it in the regenerative braking. The rest better be in your wallet.
