An “active air skirt” technology was introduced to help electric cars drive faster and longer
Automobile manufacturers are constantly looking for ways to increase the range and improve performance. Another solution was presented by Kia and Hyundai – they presented the so-called “Active Air Jacket” (AAS).
The design is installed in front of the wheels but behind the front bumper to minimize turbulence. It is activated when the car speed reaches 80 km/h and deactivated when the speed drops below 70 km/h. In testing the Genesis GV60, Active Air Jacket technology resulted in a 0.008 reduction in drag coefficient (Cd), improving drag by 2.8%.
The developers also said that their system will also provide advantages at higher speeds, for example, at 200 km/h, the downforce increases.
“AAS is expected to have an impact on SUVs, where it is difficult to improve aerodynamic performance. We will continue to work to improve the driving performance and stability of electric vehicles by improving aerodynamics,” said Sung Hyun Cho, Vice President and Head of the Mobile Body Development Group of Hyundai Motor Group.
