In a world where energy efficiency has become a priority, Hyundai Motor Group and Kia Corporation stand out by introducing a major innovation: the Active Air Skirt (AAS). This technology, designed to optimize the aerodynamics of electric vehicles, could well be a game-changer in the automotive industry.
What is AAS and how does it work?
AAS is an ingenious system that manages the flow of air under the vehicle’s bumper. It uses actuators to raise or lower an integrated diffuser, thereby regulating turbulence around the front wheels at high speed. This system automatically activates above 80 km/h to reduce aerodynamic drag and retracts below 70 km/h.
The impact of AAS on the autonomy of electric vehicles
The effectiveness of AAS was demonstrated on the Genesis GV60, where it reduced the aerodynamic drag coefficient by 2.8%. This improvement results in an increase of approximately 6 km in the vehicle’s range. In addition to increasing range, AAS improves traction and vehicle stability at high speeds.
The AAS is designed to withstand speeds in excess of 200 km/h, thanks to the use of robust rubber materials. This feature ensures long-term durability and minimizes the risk of damage from external objects.
Patents and production prospects
Hyundai and Kia have filed patent applications for the AAS in South Korea and the United States. They are considering mass production after conducting extensive durability and performance testing. This technology is particularly promising for models such as SUVs, where improving aerodynamics represents a major challenge.
Other aerodynamic innovations
In addition to AAS, Hyundai and Kia are developing other aerodynamic technologies, such as rear spoilers, active air flaps and ground clearance reducers. The Hyundai IONIQ 6, for example, boasts an exceptional aerodynamic drag coefficient of 0.21, the best in the world for an electric vehicle.
The introduction of the Active Air Skirt by Hyundai and Kia represents a significant step forward in the development of more efficient and stable electric vehicles. This innovation underlines the commitment of the two automotive giants to sustainable electric technologies and paves the way for a new era of optimized electric mobility.
