The 2012 Mercedes-Benz CLS63 AMG is set to make its world debut at this week’s Los Angeles Auto Show, but before the live reveal the German automaker decided to share a sneak preview of its sleek new design.

Although the current CLS AMG is powered by Mercedes-Benz’ sensational 6.2-liter V8, the 2012 model will make the switch to the automaker’s latest 5.5-liter turbocharged V8. Despite the decrease in displacement, the CLS63 AMG should offer plenty of performance, with the new mill rated at 518 horsepower and 516 lb-ft of torque. A Performance Package will also be on offer, boosting power to 550 horsepower and 590 lb-ft of torque.

In addition to the boost in power, fuel economy is projected to increase by 33 percent to 16 city, and 21 highway miles per gallon. Shifting duties for the CLS63 AMG will be handled by Mercedes-Benz’ seven-speed multi-clutch transmission.

As with the powertrain, the features list is equally impressive: COMAND with 40GB Hard-Drive GPS Navigation, Bluetooth interface, 14-Speaker harman/kardon LOGIC7 surround sound system with Dolby Digital 5.1, HD radio, in-dash 6-disc DVD/CD changer, in-dash SD card reader, iPod/MP3 media interface, Sirius Satellite Radio, power tilt/sliding sunroof with one touch pen/close, multifunction leather sport steering wheel with shift paddles, 14-way power adjustable seats with three position memory for seats, heated front seats, headlamp cleaning system and much, much more.

As with any Mercedes-Benz wearing the AMG designation, CLS63 will sport improved suspension, braking and aerodynamic touches to boost performance in all areas from standard CLS model. The lesser CLS, known as the CLS550, will be powered by a 4.7-liter V8 with 402 horsepower and 443 lb-ft, of torque.

Sales of the CLS 63 AMG should begin in summer 2011. Segment rivals will include the new Porsche Panamera Turbo and the high-performance version of Aston Martin’s new Rapide.
