The next generation version of Mercedes-Benz CLS, the four-door coupe that kicked off a design revolution of sorts in the automobile world back in 2004, is set to make its debut at the Los Angeles motor show this week.

Underpinned by the MRA platform that forms the basis of new E-Class, the new CLS is expected to be slightly longer and wider than the previous model, with an even more elegant fastback roofline. While we’re all waiting for the full reveal at LA, the German carmaker has released a teaser video that shows off the swooping silhouette, grille, moving headlights etc.
