The range of electric cars is heavily dependent on external factors such as temperature, terrain, and air resistance. However, Hyundai has recently introduced a new technology called Active Air Skirt (AAS) to improve the aerodynamics of their electric cars, enabling them to travel faster and farther.
Developed by the Hyundai Motor Group, which includes Hyundai, Kia, and Genesis, the AAS system is a mechanism that lowers the air dam in front of the front wheels to minimize the airflow’s impact on the tires. The dam is activated when the car reaches speeds above 80 km/h and automatically retracts when the speed drops below 70 km/h. Testing on the Genesis GV60 model showed that the AAS reduced the drag coefficient (Cd) by 0.008, which is a 2.8% reduction.
At higher speeds, the air resistance on the car increases, making the AAS even more effective. Hyundai also claims that the AAS helps increase downforce and operates at speeds above 200 km/h. The AAS operates on a similar principle to racing car designs.
Sun Hyung Cho, Executive Vice President and Head of Vehicle Frame Development Group at Hyundai, stated, “This technology is expected to have a greater impact on models such as SUVs that have challenging aerodynamic performance. We will continue to enhance the driving performance and stability of electric vehicles through aerodynamic improvements.”
Hyundai has been focusing on the development of new technologies for electric cars, resulting in a range of exciting features. For example, their Ioniq 6 electric coupe is equipped with active air curtains, wheel wind deflectors, wheel gap reducers, and a rear spoiler – all aimed at reducing the drag coefficient.
The AAS technology is still in the development stage. Hyundai has filed patents for it in both South Korea and the United States, and they plan to incorporate it extensively into their future products.
