We’ve seen some teaser pics last week, now here’s a video that previews the 2018 Mercedes-Benz CLS. The third-generation four-door coupe will make its world debut at the 2017 LA Auto Show later this week.

The official video shows the new CLS’ studded grille and LED Multibeam front and rear lights. But most importantly for this car, we get a glimpse of the four-door coupe’s trademark arching roofline. The video ends with a silhouette of the curvy shape. Last week’s teaser images showed the car’s inverted L-shape LED daytime running lights.

Mercedes-Benz labels the video above as an exterior design teaser, which leads us to presume that there will be one focusing on the cabin, soon.

The sole released image of the interior so far shows the brand’s widescreen cockpit as seen on the E-Class. It’s a long panel combining the digital instruments and centre screen, sitting above four turbine-style vents with ambient lighting. The pic also shows the Energising comfort control system on the display. A clear, full view can be had below, in our spyshot gallery.

Engine options should include a range of four- and six-cylinder engines, including mild hybrids like the M264 (in the C238 E-Class Coupe and A238 E-Class Cabriolet) and M256 (in the W222 S-Class). It is said that there will be additional AMG versions beyond the expected CLS 63, and a CLS 53 is tipped to be the first model to get the ’53’ suffix.

Mercedes says that the new CLS is “the original, perfected.” It will take some car for this third-gen to even match the impact the original made back in 2005, something the W218 of 2011 failed to do. Just a few days more to see if this one wows.
