Mercedes-Benz Concept IAA Transforms its Shape


Ahead of this week’s Frankfurt International Motor Show, Mercedes-Benz unveiled a new sleek concept named IAA (Intelligent Aerodynamic Automobile) with active aerodynamics that change the shape of its body. The Mercedes-Benz Concept IAA is two cars in one: an aerodynamics world champion with a Cd value of 0.19 and a four-door coupé embodying irresistible design. The concept switches automatically from design mode to aerodynamic mode when the vehicle reaches a speed of 80 km/h (about 50 miles per hour), whereby numerous aerodynamics measures alter the shape of the vehicle.


Inside, the Concept IAA continues the design line of the S-Class and S-Class Coupé, offers new touch-based functions and provides an idea of what the interior of a business saloon might look like in the near future. The choice of colours and materials conjures up extrovert contrasts between anthracite and white as well as between aluminium and cut glass. Elegantly curved forms, flowing lines, carefully chosen high-quality materials and the touch-based operating philosophy provide for a high level of functionality.


At the touch of a button, or automatically on reaching a speed of 80 km/h, the Mercedes-Benz Concept IAA performs a fascinating transformation in which the captivatingly beautiful four-door coupé turns into an aerodynamics world champion: eight segments extend at the rear, increasing its length by up to 390 millimetres; front flaps in the front bumper extend by 25 mm to the front and 20 mm to the rear, improving the air flow around the front end and the front wheel arches; the Active Rims alter their cupping from 55 mm to zero; and the louvre in the front bumper moves 60 mm to the rear, improving the underbody air flow.

The concept car is powered by a petrol/electric plug-in hybrid drive with a total output of 205 kW (279 hp). This provides it with a electronically limited top speed of 250 km/h  (about 155 miles per hour).
