Mercedes-Benz have showcased the Intelligent Aerodynamic Automobile (IAA) at the Frankfurt International Motor ShowMercedes-Benz already claimed the title of the manufacturer of the world’s most slippery car – the Mercedes CLA which boasts a drag co-efficient of just 0.23 Cd. Now, in a bid to slice through air more efficiently, the Germans have created what they call the IAA. The Concept IAA makes speed-sensitive spoilers and current-day active aerodynamics look cute.
This four-door coupé claims a drag co-efficient of just 0.19 and switches from the design mode to the aerodynamic mode beyond speeds of 80 km/h. Once beyond 80 km/h, the omniscient sensors activate the gamut of actuators to transform the car’s exterior dimensions. At the front, the bumper flaps extend 25 mm and 20 mm at the rear. This is done to improve the air-flow around the wheel arches. At the rear eight segments extend bringing the total increase in length to 390 mm. Even the wheels employ what they call Active Rims which alter their cupping 55 mm to zero. In order to improve underbody air-flow the front bumper retracts 60 mm to the rear.
On the inside, the Concept IAA retains the proportions of an S-Class and offers touch-based functions. With increasing emphasis on reducing their carbon footprint, car-makers are now pushing the envelope on the aerodynamics front.
