Automotive firm Hyundai Motor in collaboration with its subsidiary Kia Corp, on Monday, launched Active Air Skirt (AAS) technology to minimize the aerodynamic resistance encountered during high-speed driving and improve the driving range as well as driving stability of electric vehicles (EVs).
AAS controls the airflow entering through the lower part of the bumper and controls the turbulence generated around the vehicle wheels by operating variably according to the vehicle speed during high-speed driving, said the firm.
Located in between of front bumper and front wheels of the vehicle, AAS is intricately linked to the distinctive features inherent in its Electric-Global Modular Platform (E-GMP) designed for electric vehicles (EVs) aiding in improving aerodynamic performance.
The hidden technology operates at speeds over 80 km/h when the aerodynamic resistance becomes greater than the rolling resistance and is stored again at 70 km/h, said the South Korean firm. Additionally, the reason for the difference in deployment and storage speeds is to prevent frequent operation in specific speed ranges.
AAS can also operate at speeds over 200 km/h, the firm said, both companies have tested and reduced the drag coefficient (Cd) by 0.008, improving drag by 2.8%, by installing AAS in Genesis GV60. This is a figure that can expect an additional range improvement of about 6 km.
Early this month, Hyundai Motor and Kia Corp collaborated with Samsung Electronics to provide car-to-home and home-to-car service to its customers, along with enhancing the connectivity between residential and mobility space.
