The sporty and elegant Concept IAA show car combines expressive design with world-beating aerodynamics and efficiency. In its basic form, the design mode, the bodywork is the unification of sportiness, elegance and purism. At the touch of a button or automatically at 80 km/h and above, the vehicle undergoes an exciting transformation: The breathtakingly attractive four-door coupé turns into an aerodynamic world record holder. The Concept IAA achieves a Cd value of 0.19 in the wind tunnel and is thus unrivalled in terms of aerodynamics. In aerodynamic mode, thanks to its PLUG-IN HYBRID powertrain, it can cover 66 km on all-electric power. Thanks to the sensors installed and Car-to-X technology, the vehicle recognises obstacles and potentially dangerous situations. In its interior, white leather teams up with aluminium and crystal glass. The futuristic-looking dashboard elements and the lighting design are ahead of their time - as are the touchscreen displays.
