Stunning design, superior performance and groundbreaking efficiency - that is the all-new 2012 Mercedes-Benz CLS63 AMG. The four-door coupe features the all-new AMG V8 biturbo engine generating an output of up to 550 hp and 590 lb-ft of torque, as well as the AMG SPEEDSHIFT MCT 7-speed Sports Transmission. Fuel economy of 16 mpg city and 21 mpg highway (estimated figures) represents an improvement of up to 33 percent compared with the preceding model. The 2012 CLS63 AMG goes on sale in the US in the summer of 2011.

The combination of AMG Adaptive Suspension with the adaptive damping system and a new front axle arrangement, plus new electro-hydraulic AMG sports steering delivers supreme handling and dynamics. From a visual standpoint, the 2012 CLS63 AMG cuts an impressive figure with its athletic stance and distinctive exterior and interior design. The brand new active LED high-performance headlights are available as an option, with LED Daytime Running Lamps fitted as standard.

"The new CLS63 AMG writes the next chapter in the success story created by the CLS55 AMG and CLS63 AMG, which have been amazing our customers around the world since 2004," says Ola Kallenius, General Manager of Mercedes-AMG GmbH. "The CLS63 AMG is a unique, high-performance automobile - it sets new benchmarks in design, performance and efficiency."

As with the S63 AMG and CL63 AMG, drivers of the CLS63 AMG benefit from the new eight-cylinder motor known internally as the M 157. The new AMG 5.5-liter V8 biturbo engine features a combination of high-tech components - in addition to spray-guided gasoline direct injection with piezo injectors, it boasts an all-aluminum crank-case, four-valve technology with variable camshafts, air-water charge-air cooling, generator management and stop/start system. From 5,461 cm3, the eight-cylinder generates a maximum output of 518 hp and 516 lb-ft of torque. In combination with the optional AMG Performance Package, output rises to 550 hp and 590 lb-ft. Both versions of the CLS63 AMG deliver exceptional performance - acceleration from 0 to 60 mph takes 4.4 and 4.3 seconds respectively, with a top speed of 155 mph in the standard version and 186 mph with the Performance Package (electronically limited. All figures are preliminary).

The key difference between the two performance levels is the maximum charge pressure of the twin turbochargers, which is 14.5 psi in the standard CLS63 AMG and 18.8 psi with the Performance Package. Moreover, the version with the Performance Package boasts an attractive engine cover with carbon-fiber applications.

Quantum leap - 33 percent improved fuel economy
Despite a substantial increase in output compared with the preceding model with the AMG 6.3-liter V8 naturally aspirated engine producing 507 hp and 465 lb-ft, the new CLS63 AMG goes 4 miles further in the city on one gallon of fuel, making it 33 percent more fuel-efficient - no less than a quantum leap. With estimated fuel economy of 16 mpg city and 21 mpg highway, the new AMG V8 coupe is not only considerably better than all of its direct competitors in the exclusive segment of high-performance four-door coupes, it is also more fuel-efficient than many far less potent vehicles. Both performance variants have identical fuel economy.
