The enormous Korean auto group incorporating Hyundai and Kia has detailed a brand new aerodynamic help it’s planning to roll out on all future EVs that can lower drag on even the slipperiest of its fashions, enhance downforce, improve high-speed stability and traction all whereas including as much as six kilometres of vary.
Dubbed the Energetic Air Skirt (AAS) the brand new tech has been developed by each Kia and Hyundai and the group’s luxurious arm, Genesis. It consists of a pair of wind deflectors that decrease at speeds of over 80km/h.
As soon as deployed the spoilers cut back the turbulence that builds-up across the entrance wheels, decreasing drag by as much as 2.8 per cent on the modified Genesis GV60 SUV the know-how has been testing on – equating to a 0.008Cd discount in its drag coefficient – including a real-world six kilometres to the vary.

Created to stay inside the house between the entrance bumper and the entrance wheels the AAS spoilers routinely retract when velocity drops under 70km/h.
In testing the air skirt is designed to function at speeds as much as 200km/h.
When you’re questioning why the energetic air skirts solely deploy across the entrance wheels it’s as a result of Hyundai Motor Group’s E-GMP electrical automobile platform – on which they’re first deployed – already has an optimum flat flooring between the axles.
So efficient is the brand new tech Hyundai Motor and Kia have now utilized for patents in South Korea and the US.
Each manufacturers plan to roll out AAS of their next-generation automobiles as soon as full sturdiness and efficiency assessments have been accomplished.
When the AAS arrives on the manufacturers next-gen EVs they are going to be a part of the energetic air flaps, wheel air curtains, wheel hole reducers and separation traps that the wind-cheating Hyundai Ioniq 6 has exploited to decrease its drag coefficient to a class-leading 0.21Cd.
Hyundai’s mobility physique improvement group boss, Solar Hyung Cho, mentioned: “This know-how is anticipated to have a larger impact on fashions corresponding to SUVs the place it’s tough to enhance aerodynamic efficiency.
“We’ll proceed to try to enhance the driving efficiency and stability of electrical automobiles by means of enhancements in aerodynamics.”
