The covers are coming off the new second-generation Mercedes CLA at CES this week, but just one day before the big debut Mercedes has released one last teaser video on Facebook that gives us the most revealing look yet at the coupe-style sedan. Specifically, we're looking at the Edition 1 that will be available for the first 12 months of sale, which will boast more equipment and some styling tweaks to set it apart.

The model in the teaser appears to be adorned with bright orange accents inside and out. We get a close look at the new reshaped headlights and taillights that help distinguish it from the larger A-Class as well as a clear look inside the luxurious cabin. A separate photo posted on Instagram also shows the company's design boss Gorden Wagener posing next to the new CLA hiding under a sheet.

If you're wondering why the new Mercedes CLA is debuting at CES instead of the Detroit Auto Show this month, aside from not being at the Motor City this year, the automaker will be introducing some clever new tech powered by the latest version of Mercedes' MBUX infotainment system.

Last week, Mercedes announced that the CLA will have an "Interior Assistant" that allows the driver to activate the interior lighting using hand gestures. More info about this innovative new tech will be revealed at CES this week.

Technical details are still being kept under wraps, but the new A-Class should give us an idea of what to expect. Engine options should carry over, so the US model will likely be powered by a 2.0-liter turbocharged inline-four at launch that produces around 200 hp mated to a seven-speed dual clutch transmission. As well as the MBUX infotainment system, the CLA will also inherit its A-Class sibling's dual 10.25-inch screen setup. More potent models will eventually join the CLA line-up including a 302-hp CLA35 and 400-hp CLA 45. We'll have more details to share when the new 2020 Mercedes-Benz CLA breaks cover at CES on January 8.
