Introduced on Wednesday: 2012 Mercedes-Benz CLS63 AMG
What is it? A more fuel-efficient AMG.
What makes it tick? The new twin-turbocharged 5.5-liter V-8 engine, which makes 550 horsepower and 590 pound-feet of torque with the optional AMG Performance Package (without, those figures are 518 and 516, respectively). The Speedshift MCT 7-speed sport transmission helps to achieve an estimated fuel economy of 16 miles per gallon in the city and 21 on the highway, a 33 percent improvement over the outgoing 6.2-liter.
How’s it look? Rendered in matte gray, the upscale CLS sedan morphs into something as menacing as a Predator missile, under which are aluminum doors, hood, front clip and trunk lid. The optional AMG Performance package adds a carbon-fiber hood and rear spoiler along with suspension upgrades and nicer trim.
