Mercedes-Benz Concept IAA (2015)
2015 Mercedes-Benz Concept IAA is two cars in one, because it is an aerodynamics world champion and a four-door coupe. IAA stands for Intelligent Aerodynamic Automobile, and this car is a concept which applies interesting technologies for the first time. For instance, it switches automatically from design mode to aerodynamic mode when the vehicle reaches a speed of 80 km/h. As a result many aerodynamics measures alter the shape of the vehicle. Inside, the "Concept IAA" is a future vision for the interiors of the S-Class and S-Class Coupé.
