The shape of the new FABIA improves its ecological footprint
Good aerodynamics reduces the energy required for a car to move. Thanks to well-conceived measures, the new FABIA has made a significant contribution to reducing consumption and emissions, for example, thanks to active blinds. Whenever the system assesses the need for engine cooling as low, the active blades located in front of the radiator partially close and reduce the air flow through the engine compartment. This saves 0.2 litres of fuel per 100 kilometres at a speed of 120 km/h. The model’s aerodynamic drag is further reduced by the holes in the front bumper, called the Air Curtain (1), the optimised wheels (2), the shape of the exterior mirrors (3), the extended spoiler of the fifth door (4) and finlets along the rear window (5).
Did you know that…
… automotive aerodynamics is tested both physically (in a wind tunnel) and with simulations? The fourth-generation ŠKODA FABIA spent over 100 hours in a wind tunnel. In addition, it completed over 3,000 computer simulations, which took tens of thousands of computing hours.
Compared with the previous model, the automobile drag coefficient (cx) has dropped from 0.32 to 0.28, making it the best in its class.
„Tuning the aerodynamics of any car type is specific. Different body shapes, car dimensions, platforms and wheel dimensions affect the flow around the car in different ways. The hatchback has fewer surfaces for airflow to be optimised than longer cars do. Although the new FABIA has grown in size compared with its predecessor and its front surface has increased about 3 percent, its aerodynamic drag is now almost 10 percent less than before. In the standard WLTP cycle, this represents a reduction of almost 3 g of CO2 emissions per kilometre.“
