Standing still, the IAA concept previews the design of future Mercedes-Benz models, like the S-Class sedan and CLS four-door coupe. At the touch of a button or above 50 mph, the concept transforms from a sexy four-door coupe into an aerodynamic vehicle with an extremely low 0.19 coefficient of drag. Cars that have the ability to raise their spoilers and other aerodynamic parts at speed aren’t something new, but the IAA concept takes it a step further.

Above 50 mph, several exterior changes take place to make the IAA concept more aerodynamic. For starters, flaps in the front bumper shift outward to improve the airflow to wheels and the louver in the front bumper moves rearward to improve airflow to the underbody. Even the wheels transform as the five-spoke wheels fill the gaps to become flat discs. Lastly, at the rear an extension extends 15 inches to better optimize the airflow at the rear of the concept.

The Mercedes-Benz IAA concept is powered by a plug-in hybrid powertrain that generates 279 horsepower and can travel up to 41 miles in electric mode.
