New Active Air Skirt Technology Enhances Efficiency and Performance of Hyundai and Kia EVs

Hyundai and Kia have unveiled an innovative technology called Active Air Skirt (AAS), which will be incorporated into their future electric vehicles (EVs). This cutting-edge system effectively reduces aerodynamic drag and enhances high-speed stability, resulting in improved efficiency and performance.

The AAS technology, developed by both brands and Hyundai’s luxury arm, Genesis, consists of spoilers deployed in the space between the front bumper and the front wheels. This active aero aid not only lowers turbulence but also increases downforce, promoting better traction.

By controlling the airflow around the wheels, the AAS manages to significantly reduce drag. When the system is activated at speeds higher than 80km/h, the drag coefficient is reduced by 0.008Cd, translating to a 2.8% improvement. Consequently, the range of EVs equipped with the AAS technology is extended by approximately 6km, providing an important boost for electric mobility.

Notably, the AAS spoilers are deployed exclusively around the front wheels due to the design of Hyundai Motor Group’s E-GMP electric vehicle platform, which already creates a flat floor between the axles.

The effectiveness of the Active Air Skirt technology has prompted Hyundai Motor and Kia to apply for patents in both South Korea and the United States. Once durability and performance tests are completed, these Korean automakers plan to integrate the AAS system into their next-generation vehicles.

With a strong commitment to optimizing aerodynamics, Hyundai and Kia have already introduced various features to their EV lineup, including pop-up spoilers, active air flaps, wheel air curtains, wheel gap reducers, and separation traps. These advancements have contributed to extraordinary drag coefficients, as exemplified by the Hyundai IONIQ 6’s outstanding 0.21Cd.

Sun Hyung Cho, the head of Hyundai’s mobility body development group, expressed optimism about the implications of the new technology. He stated that the AAS system would be particularly beneficial for SUV models, where improving aerodynamics presents unique challenges. Hyundai and Kia are determined to continue refining driving performance and stability through ongoing aerodynamic improvements.

In conclusion, the introduction of the Active Air Skirt technology marks a significant milestone in optimizing the efficiency and performance of Hyundai and Kia EVs. By reducing drag and enhancing stability, this innovative system paves the way for more advanced and capable electric vehicles in the future.

Definitions:
1. Aerodynamic drag: The resistance encountered by a vehicle as it moves through the air, which affects fuel efficiency and performance.
2. Downforce: The downward pressure exerted on a vehicle that increases traction by improving the grip of the tires on the road.
3. Drag coefficient: A measure of how streamlined an object is, indicating the air resistance it experiences while moving through the air.
