The Mercedes-Benz Concept IAA will make its debut at the 2015 IAA - short for the Frankfurt motor show's German name 'Internationale Automobil-Ausstellung' - but the vehicle appears to be a clever play on words, with an embedded caption in the image stating IAA stands for Intelligent Aerodynamic Automobile.

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.

Mercedes-Benz “Concept IAA” (Intelligent Aerodynamic Automobile)

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.
