Mercedes’ mysterious concept teaser shot has gained more context through the addition of another one showing the whole outline of the vehicle. It’s very obviously a four-door sedan with a sloping roofline and tapered rear.

The automaker calls it IAA, short for Intelligent Aerodynamic Automobile and says it’s really “two cars in one: an aerodynamics world champion and a four-door coupé embodying irresistible design.”

Styling-wise and judging solely based on the two unrevealing images seen so far, there is a bit of an Audi A7 vibe about this car, although once we see it fully unveiled and with all details visible that impression may drastically change.

It’s set to be revealed tomorrow at 7:30 PM Central European Summer Time but until then do check out the slightly brightened up new teaser shot posted below. It shows no details whatsoever, but emphasizes the flowing lines of the body in a nice artsy, sculptural kind of way.
