The extensive collaboration between aerodynamics engineers and designers can be seen in the streamlined bodywork of the SCALA, for example, which has been developed using advanced numerical simulations and a virtual wind tunnel. To improve its aerodynamics, the body has been made slightly narrower and slimmer at the rear – aiming to achieve a so-called boat tail – and yet, the SCALA still offers outstanding head and elbow room in the rear. With a lot of refinement and using numerous details, ŠKODA has significantly reduced drag even further. Some of these details immediately catch the eye, such as the Air Curtains in the front bumper and the optional Aero alloy wheels. The Air Curtains direct air through the sides of the front bumper as well as through the front wheels in a controlled manner and reduce air vortices and unwanted airflow. This effect is supported by the special, newly developed 16-inch Hoedus, 17-inch Propus and 18-inch Vega Aero wheels. Their spokes have been widened using aerodynamically optimised vanes that provide smoother airflow along the outside of the wheels whilst the vehicle is in motion.
