The 2011 Mercedes-Benz CLS is scheduled to debut at the Paris Motor Show in October, but several photos of the car’s interior and exterior have already leaked.  The second-generation model, codenamed C218, has a tough act to follow– its swoopy predecessor single-handedly created the market for “four-door coupes.”  The new car inherits much of its styling from the Concept Shooting Brake, including a prominent grille, aggressively styled front bumper, daytime LED running lights, and a long hood.

The new CLS sports two gasoline engine options– the the CLS 350 CGI with a new direct-injected 3.5L V6 putting out 301 HP and 272 lb-ft of torque and the CLS 550 CGI, with a new 4.6L twin-turbo V8 delivering 429 HP and 516 lb-ft of torque.  The company’s 4Matic four-wheel-drive system will likely be available on the 550 CGI.  Mercedes will offer two diesel options (outside America), the CLS 350 CDI with a 3.0L V6 producing 248 HP and the CLS 250 CDI with an inline-4 putting out 201 HP.

AMG will join the party with the 2011 CLS63 AMG, sporting the tuner’s new 5.5L twin-turbo V8 putting out 544 HP and 590 lb-ft of torque.  An optional Performance Pack will be available, boosting power to about 570 HP and 663 lb-ft of torque.
