The Hyundai motor group has developed a new active aerodynamic device called the active air skirt (AAS), which it expects to reduce a car’s drag coefficient by 2.8%.
That might sound like a modest amount, but every tiny increment counts here, and the company says the device could improve the range of electric cars cruising at higher speeds.
The AAS has already been tested on the Genesis GV60 electric SUV. It consists of two panels that drop down ahead of the front wheels at 50mph, the speed at which Hyundai says aerodynamic resistance becomes greater than rolling resistance.
