The current Mercedes-Benz CLK is something of an enigma - built around the C-Class platform, styled like the E-Class, and priced in between the two, the car sits in its own unique segment and has no direct competition from its German rivals. Its sales history has been a strong success, especially in the U.S., but reports are surfacing that the German carmaker is planning to end the CLK name and instead brand its successor as an 'E-Class' Coupe and Convertible. In the press release for the new ConceptFASCINATION Mercedes-Benz states that its designers are working on a 'future E-Class Coupe.' This goes towards explaining why Mercedes would drop such an important nameplate - the main reason is that the car's successor will be based on the same platform that will underpin the next-generation E-Class due next year. Meanwhile, near production-ready test mules for the E-Class Coupe and Cabrio have been spotted near Mercedes headquarters in Germany and now these latest spy shots give us a clue as to what the final car will look like.
