Korean automaker has just introduced a new technology called Active Air Skirt (AAS), which helps the car to go faster and farther.
The system deploys an air-splitting device under the car to minimize air turbulence caused by the wheels. The system is activated when the car exceeds a speed of 80 km/h and retracts automatically when the speed drops below 70 km/h. When tested on the Genesis GV60, the AAS helped reduce the drag coefficient (Cd) to 0.008, improving aerodynamics by an additional 2.8%.
Above all, Hyundai states that AAS will also be useful when driving at higher speeds. The system also increases downforce and operates at speeds above 200 km/h. In general, most racing cars have some aerodynamic details on the body to reduce turbulence just in front of the wheels. However, in this case, it appears that Hyundai plans to use AAS on certain types of vehicles.
Sun Hyung Cho, Vice Chairman and Head of theVehicle Development Group at Hyundai, said: “This technology is expected to have a greater impact on models such as SUVs, which are difficult to improve in terms of aerodynamic performance. We will continue to strive to improve the driving performance and stability of electric vehicles through aerodynamic improvements.”
Increased benefits are crucial in the electric vehicle market as all brands want to expand their range of operation as much as possible. The AAS technology is not surprising to those who pay attention to the technologies that Hyundai is using on its electric vehicles. The Ioniq 6 has used active air vents, wheel covers, wheel gap reducers, and a rear spoiler, all aimed at reducing drag coefficient.
Currently, AAS is still under development. The company has filed for patents in both South Korea and the United States. Hyundai said they plan to “consider mass production after durability and performance testing.”
