Hyundai and Kia have just unveiled the technology “ Active Air Skirt » (AAS). Its role is to minimize the aerodynamic resistance generated when driving at high speed and therefore to improve the range and stability of electric cars. But will it one day be deployed on production models?
Hyundai and Kia showcase technology Active Air Skirt
Everything is possible to improve the performance of electric vehicles. This is a subject on which Hyundai and Kia have been trying to innovate for several years. The two South Korean brands have just presented a technology called “ Active Air Skirt » (AAS). Installed between the front bumper and the front wheels of an electric car, this small block allows “ control the turbulence generated around the wheels and stabilize the car ».

It operates at speeds above 80 km/h when aerodynamic resistance becomes greater than rolling resistance. It disappears when the car goes below 70 km/h. This technology capable of controlling the flow of incoming air would also improve the autonomy of models equipped with it. According to Hyundai and Kia, AAS effectively reduces the drag coefficient of electric vehicles.
Enough to gain a few kilometers
The two brands say they are able to reduce this coefficient by 0.008. That’s an improvement of 2.8%. Installed on the Genesis GV60, the AAS allows an improvement in autonomy of approximately 6 km. It’s not huge, but it’s still a big deal. Currently, the AAS system is under development. Patents have been filed in South Korea and the United States. Once the tests are completed, mass production could be considered to equip all the models.
Hyundai and Kia believe their technology could have “ a greater effect on large models, particularly SUVs “. Vehicles on which it is more difficult to improve aerodynamic performance with usual techniques. The two Asian brands also apply other technologies to try to improve the autonomy of their models: active air shutters, wheel air curtains, wheel gap reducers or even separation hatches .
