The next-gen model should debut around 2018 and borrow all the major technological breakthroughs that come with the E-Class. Nobody has seen a single internal sketch or scale model, let alone a test prototype. So we can't say for sure if this rendering is right or wrong.
But we like what Remco M has done and are going to share his vision with you. He believes the four-door coupe will receive an "upside down" grille that will also be featured on the AMG GT3 race car and upcoming SL facelift.
Around the back, the rendering shows a hint of S-Class Coupe and a dash of AMG GT. Overall, the boot will be one of the trickiest pieces of design to get right because both the Porsche Panamera and Audi A7 are going to change.
Of course, the interesting part of the next CLS is what's under the bonnet. This four-door coupe has always been prized for the hooligan nature of its V8 AMG engines. But Mercedes may be forced to downsize from 5.5-liter to 4-liter.
It's not all bad news though, as the first inline-6 turbos will be ready by 2018. One of them will be a 2.9-liter diesel that will be available in performance flavors with a multi-turbo setup.
