Mercedes-Benz teases E-Class Coupe ahead of December 14 reveal

If you've seen the S-Class or C-Class coupe, you know what to expect.

Mercedes has a simple formula: After the sedan is on sale, reveal the coupe variant. It did so with the S-Class and C-Class, and now, it's about to do it again with the E-Class.

Mercedes-Benz will unveil the E-Class Coupe in full on Wednesday, but ahead of pulling back the curtain, it's tossed out a teaser video. There aren't a whole lot of surprises here -- the front end looks like the E-Class sedan, as does the interior layout, as does the screen that replaces the gauge cluster.

What's new, though, is the rear end -- sort of. It has a smooth look, but it's nearly exactly the same as the C-Class and S-Class coupes. That's not a surprise, since this new generation of coupes shares the same look, as opposed to the previous generation, where each coupe more closely resembled each sedan. We'll get a full look at it on Wednesday.
