the Concept Intelligent Aerodynamic Automobile isn't a sports car in the traditional sense of the word. There's no fire-breathing engine under the hood, and it's not connected to the AMG engineers in Affalterbach.
What has pushed the Concept IAA up to number four on our list is the clever aerodynamics tech that kicks in at 80 km/h (50 mph). Eight segments built into the rear of the car extend the tail section by up to 390 mm (15 in), and flaps built into the front bumper protrude by 25 mm forward and 20 mm towards the rear of the car to improve airflow around the front.

By moving these elements, in tandem with the moving
elements on the wheels, the car's drag coefficient drops from 0.25 to a
super-slinky 0.19, helping to eke out a few extra miles of all-electric
power.
