Breaking records using digital aero development

The Mercedes-Benz Concept IAA

When the Mercedes-Benz management decided in late summer 2014 to build the Concept IAA (Intelligent Aerodynamic Automobile) show car for the 2015 Frankfurt Automobile Show, it was clear that this would be a very challenging year for all involved groups like stylists, CAD-designers, manufacturers and aerodynamic engineers.

The idea was to achieve an extraordinary low drag coefficient combined with an expressive sporty styling. This conflict of aims could be resolved by the development of active parts which can transform between “styling” and “aero” mode depending on the driving condition of the car. Due to the very short development time, the aerodynamic development was performed exclusively digital until the final validation measurements in the wind tunnel.

The presentation will show the digital aerodynamic development of the IAA-Concept-Car with  STAR-CCM+®. It will show the function of the transforming features of the car and its evaluation in the wind tunnel.
