Some reports have suggested the four-door coupe CLS will be based on an S-Class platform but it will actually be based on the E-Class. In keeping with its earth eco responsibilities, Mercedes will for the first time, offer a BlueHybrid version of its sporting 2+2 seater using the same engine as the S400 BlueHybrid. Additionally a few engines found in the E-Class should make their way into the CLS engine bay too, meaning petrol and diesel as well as a 400kW / 536hp-plus AMG.

The CLS practically invented its segment when it came into the market in 2004. It gave people with families of about three or four a spacious car with four doors plus the driving characteristics of a two-door sports coupe.
