THE electricity is starting to play an increasingly important role in the catalogs of car manufacturers. In an attempt to improve efficiency of their own electric vehicles, Hyundai and Come on they unveiled a new system called Active Air Skirt.
The technology in question focuses on reduction of aerodynamic drag at high speeds, improving autonomy and the stability of the electric vehicle that incorporates it. Essentially it is an active aerodynamic “apron” that controls the flow of air at the bottom of the bumper and manages any volatility is created around the vehicle.
The system is positioned between the front bumper and the wheels, while it remains activated when the car exceeds the speed of 80 km/h.
The AAS covers only the front of the tireswhich is more effective in improving aerodynamic performance, especially when combined with the flat floor offered by E-GMP platform. In addition, partial rather than full coverage of the front contributes to increase in vertical force and consequently the adhesion and the stability of the vehicle in higher speeds.
It can even work when traveling at a speed that exceeds 200 km/hthanks to the use rubberwhich is known for its durability.
According to the Koreans, the tests showed that o drag coefficient (Cd) of Genesis GV60 decreased by 0,008resulting in its improvement drag against 2,8%, when the particular system was installed. This, in turn, increased it autonomy against 3,7%.
