Aerodynamics has at all times performed an enormous function in automobile design, however it’s particularly essential for electrical automobiles, the place each bit of additional vary that may be eked out makes a distinction. Hyundai Motor Group has launched the primary particulars on its new Energetic Air Skirt tech that’s in improvement, which is able to enhance the vary and high-speed stability of the corporate’s upcoming EVs.
Demonstrated in prototype type on a Genesis GV60, the Energetic Air Skirt (AAS) consists of two flaps underneath the nostril of the automobile, positioned simply forward of the entrance wheels to direct air circulation across the tires. These deploy at 50 mph and retract once more at 43 mph; Hyundai says the staggered speeds are “to forestall frequent operation in particular velocity ranges.” They’ll work at as much as 124 mph, and the decrease part of the skirts are made from rubber so that they received’t be broken by obstacles.
With the AAS put in, the Genesis GV60’s coefficient of drag was decreased by 0.008, downforce was improved by 2.8 p.c and the full vary was elevated by about 4 miles. Hyundai says the skirts solely have to be positioned in entrance of the tires and never throughout all the entrance finish due to the E-GMP platform’s flat flooring. Along with the higher aero, the skirts “additionally perform to reinforce downforce of the automobile, thereby enhancing automobile traction and high-speed stability.”

The AAS will probably be discovered on HMG manufacturing automobiles, and the corporate says it will likely be much more efficient for bigger EVs:
Hyundai Motor and Kia have utilized for associated patents in South Korea and the US, and plan to think about mass manufacturing after sturdiness and efficiency checks.
“This know-how is anticipated to have a higher impact on fashions reminiscent of SUVs the place it’s tough to enhance aerodynamic efficiency,” stated Solar Hyung Cho, Vice President and Head of Mobility Physique Improvement Group at Hyundai Motor Group. “We are going to proceed to try to enhance the driving efficiency and stability of electrical automobiles by enhancements in aerodynamics.”
The three-row Hyundai Ioniq 7 is a probable candidate to obtain AAS first — I noticed it at Hyundai’s design heart again in 2022, and the crew touted its excessive aero targets — and it ought to make its strategy to the facelifted variations of different E-GMP automobiles just like the Hyundai Ioniq 5 and Kia EV6 as properly. HMG automobiles just like the Ioniq 6 already make use of aero tips like energetic grille shutters and air curtains.
