Mercedes-Benz Concept IAA teased ahead of Frankfurt motor show

The concept model is expected to be teased over the coming days ahead of its reveal at the Frankfurt show, and very little is currently known about the mystery car. We've split the single teaser image into two more digestible pictures to give you an idea of what it could be.

Indeed, Mercedes-Benz has only hinted that the car will feature “next level design”, and given the name Intelligent Aerodynamic Automobile, it seems clear this will be a vehicle with sleek lines - as the above image, presumably of the rear windscreen and D-pillar, suggests.

Could it be another genre-melting concept car? Could it be a high-tech replacement for a current model? We'll find out soon.

Stay tuned for more on the Mercedes-Benz Concept IAA in the coming days.
