Mercedes-Benz CLS63 AMG

The all-new CLS-Class coupe represents the first major redesign of a car that established an entirely new market segment - the four-door coupe, which combines the emotional appeal and dynamic design of a coupe with the comfort and functionality of a sedan.

The 5.5-liter version of the new direct-injection V8 engine in the 2012 CLS63 AMG is rated at 518 hp and 516 lb.-ft of torque. An optional AMG Performance Package increases output to 550 hp and 590 lb-ft of torque. Even with its high-performance, the CLS63 AMG is 26 percent more fuel efficient (est. 15 city / 23 hwy), thanks in part to an innovative ECO stopstart system. Whenever the AMG model stops in "D" or "N" with the brake pedal depressed in "Controlled Efficiency" transmission mode, the engine is automatically turned off to save fuel. As soon as the driver releases the brake, the engine computer decides which piston is in the best position for first ignition, and the direct fuel injection and multi-spark systems work with a starter motor to re-start the engine almost instantly.

The CLS63 AMG features a 7-speed MCT (multi-clutch technology) sport transmission with an innovative start-up clutch that replaces the conventional torque converter. Providing the direct feedback of a manual transmission with the total convenience of an automatic, the MCT transmission offers impressive versatility and faster shift times.

In addition to larger brakes and wider wheels and tires, the CLS63 AMG also sports a unique combination of steel coil springs at the front and AIRMATIC suspension at the rear, which provides especially responsive handling from the front suspension, while the self-leveling AIRMATIC at the rear maintains consistent ride height, regardless of the load. Along with a tubular front stabilizer bar, the CLS63 AMG is fitted with special front control arms and wheel hub carriers that provide wider track and more negative camber for even better grip in high speed curves. The CLS63 AMG rear suspension includes new track rods and push-pull rods as well as more rigid sub-frame mounts that all contribute to enhanced cornering.
