Spy Shots: 2011 Mercedes-Benz CLS AMG

The Mercedes-Benz CLS ignited the four-door coupe market when it was first introduced back in 2004, and since then we’ve seen several other luxury rivals attempt to emulate the design with cars like the 2010 Porsche Panamera, recently revealed 2010 Aston Martin Rapide and upcoming Audi A7.

Now, prototypes for Mercedes’ next-generation CLS has been spotted, revealing a few subtle clues about the new model. These latest shots show the high-performance AMG model, which is likely to be the dubbed the CLS63 in reference to its 6.2-liter V-8 engine.

Clear giveaways that this is the AMG model are the quad exhaust tailpipes, additional air vents on the bonnet, and oversized brakes.

Expect to see similar performance to that of the 2010 E63, which means an engine output of about 525-horsepower and 465-pound-feet of torque and a 0-62-mph time of around 4.6 seconds. Drive is likely to be channelled rearward via AMG’s new SPEEDSHIFT MCT 7-speed sports transmission.

The new CLS range, including the AMG model, is expected to be launched in late 2010 as a 2011 model, and positioned more upmarket to bring it in line with some of its more premium rivals. This will also allow Mercedes to introduce a second four-door coupe model, rumored to be based on its next-generation small car platform.

The new design will feature a wider track, as indicated by the extended wheel arches seen on previous test mules, and according to insiders its platform will be borrowed from the current S-Class sedan flagship.
