Mercedes CLS spied; Due for launch in 2018

Mercedes is currently testing an all-new generation of the CLS. What was once a bold and controversial design has now turned into something with a massive following, especially among enthusiasts. 

For the second-gen model, the changes in design will be evolutionary rather than revolutionary. That said, the prominent hip on the current model will be reduced for the new model and the taillights will also be horizontal rather than diagonal. Like in the new E-Class, the CLS will have two fairly big displays stacked side by side. 

Under the hood there will be no more V6 motors. Instead, Mercedes will make use of in-line six units. The popular 2.1-litre four-cylinder motor will be replaced by a more refined 2-litre unit. Unlike the current model, the next-gen CLS will be limited to a four-door coupe model. Expect it to go on sale in 2018.
