Of course that comes to no surprise as the new CLS is closely related to the latest iteration of the E-Class sharing the same platform and mechanical hardware, which means a similar line-up of direct injection petrol and turbo diesel engines hooked up to Mercedes' seven-speed automatic transmissions.
Initially, the new CLS will be available with three petrol and one diesel engine. These include a 3.5-liter V6 with 292HP, a 5.5-liter V8 with 388HP and a 525HP 6.2-liter V8 for the range-topping AMG model, and the latest version of Merc's 3.0-liter V6 turbo diesel producing 231HP.
Furthermore, according to Auto Cars 2011 sources, a hybrid version of the new CLS will definitely be in the mix. It will be equipped with the same drivetrain as the recently revealed S400 Hybrid that combines a 3.5-liter V6 petrol engine developing 279HP with a 20HP electric motor that's installed in the torque converter housing between the engine and the 7-speed automatic transmission. This particular hybrid system generates a total output of 299HP and a combined peak torque figure of 385 Nm or 283-lbs/ft.
As far as the exterior design is concerned, even though Mercedes has covered the prototype's sides and ends with more plastic cladding than a bondage club, it is evident that the overall shape of the sports saloon won't stray too far away from the current model, retaining the same characteristic low-roofed four-door profile of today's CLS.
However, expect to see some of the new E-Class' edgy design treats pass into the design of the front and rear ends and quite possibly, the shape of the rear wheel arch and the crease below the window line.
