ŠKODA has reduced the new FABIA’s drag coefficient to 0.28 (previous generation: 0.32), setting a record in the small car segment. During the development of the aerodynamics, ŠKODA predominately used what is known as CFD simulations (Computational Fluid Dynamics). Within approximately three and a half years, the ŠKODA engineers computed more than 3,000 of these fluid dynamics simulations.
Cooling shutters reduce fuel consumption by up to 0.2 l per 100 km at 120 km/h
An important aerodynamic feature is the new type of cooling shutter in the front bumper’s lower air inlet, which ŠKODA is using for the first time in this vehicle segment. Actively adjustable slats automatically close when there is little need for cooling, improving aerodynamics. This results in fuel savings of up to 0.2 l per 100 km when travelling at a constant speed of 120 km/h. For every kilometre driven with the shutters closed, the new FABIA thus emits up to five grams less CO₂. To allow for a high level of cooling or to accommodate short stops, the system opens the shutters so that the maximum amount of air can flow in.

Optimised drag at the rear and FABIA debut for aerodynamically optimised wheels
Approximately one third of a vehicle’s overall drag is caused by turbulence at the rear. The new ŠKODA FABIA has a larger roof spoiler and side finlets that optimise the air flow at the rear. Smaller and specifically designed aerodynamic wing mirror housings additionally reduce drag and direct the air flow to the rear in a targeted manner. At the front, the air is guided to flow through vents in the front bumper, known as air curtains, in a particularly aerodynamic manner close to the side of the body and the wheels. As approximately 25% of the drag is generated by the wheels alone, ŠKODA has now also fitted special plastic trims in the FABIA to improve the alloys’ aerodynamics – this is a first. These trims are suitable for the Proxima and Procyon wheels. Twelve panels now cover a larger part of the underbody instead of three, especially in the areas that are crucial for aerodynamics, such as the engine bay and the axles.
