Frankfurt Show Highlights: Mercedes-Benz IAA Concept

Probably this is the star of 2015 Frankfurt Motor Show. At this year’s auto show, Mercedes revealed its latest concept car, named IAA. It stands for Intelligent Aerodynamic Automobile. The concept car deserves the star of the show because it’s futuristic, it’s a high-tech car, and it’s innovative.

IAA’s exterior styling is like the combination between CLS and F 015 Concept. At the front, its design reminds me of F 015 Concept. It can be seen from its unique-shaped headlights which has the same form like the previous concept. The concept car has an aerodynamic line from the front to the rear. The C-pillar line is designed to be a coupe-like. Its design reminds me of Audi A7 and the concept’s design could be the preview of next CLS-Class. At the rear, Mercedes’ designers put a unique design featuring thin LED taillights that sweeps away from left to right.

As the name suggests, the 4-door car shows the latest aerodynamic technology. Mercedes said that IAA Concept had active aerodynamic features. When you drive at 80 km/h, the mode changes automatically from Design Mode to Aerodynamic Mode. First, the fin in the front bumper retracts by 60 mm to improve flow along the underbody. Furthermore the flaps in the front bumper extends by 25 mm and rearwards by 200 mm to improve airflow around the front-end and the front wheel arches.

The active wheel rim change their cupping from 50 mm to 0. And the most interesting part of active aerodynamic feature is when the rear-end extending its size up to 390 mm. The result is its coefficient of drag 0.19. It means that the lowest in the world today.

The concept car isn’t all about the aerodynamic thing. The German carmaker put the autonomous feature to the study car. Mercedes deploys many sensors and modules which allow autonomous driving and car-to-X communication. This feature enables communication between IAA and other vehicles on the road or even with other sources of information. Mercedes IAA Concept comes with petrol engine that is combined with plug-in hybrid which has total output 275 hp and its top speed is electronically-limited to 250 km/h. I hope the aerodynamic tech can be implemented in next-gen Mercedes’ car, at least for its upcoming supercar.
