Hyundai’s new invention to achieve autonomy in its electric vehicles

We are heading towards a totally electrified world in which what matters most is efficiency. Although for the end user, what is really important is the autonomy that their electric car can have, which is what determines its use. That is why manufacturers are focused on developing solutions that increase this characteristic of vehicles. For example, Hyundai has a new invention to shave miles of autonomy. It is currently in the testing phase, although the probabilities of reaching production are high.

They have named this technology as Active Air Skirt (AAS), which could be translated in Spanish as active air skirt. It is an aerodynamic element that is installed between the front bumper and the wheels, so that it remains hidden during normal use, but is deployed when necessary. The objective is to reduce excess resistance and turbulence generated at high speeds. So we are not only talking about autonomy, but also about improving the stability of the vehicles that mount it.

Its operation is quite simple, since this aerodynamic skirt deploys when the car exceeds 80 km/hy remains out until you drop below 70 km/h again. During that time it is reducing the drag coefficient and helping to improve the efficiency of the model. The fact that there is a disparity between the speeds is so that it is not constantly entering and leaving when cruising at that speed. The user will immediately notice a more stable driving and less air noise.

This AAS only covers the front part of the tires and that is because it has been designed for vehicles that use Hyundai’s E-GMP platform. This specific architecture for electric vehicles already has a flat floor to promote aerodynamics, so only the wheel section needed to be improved. They talk about what can work speeds greater than 200 km/h safely thanks to being made of a rubber material that prevents external objects from jumping out.

In the tests carried out by the Korean brand, quite positive results have been seen. Mounted on the Genesis GV60, it has improved aerodynamics by 2.8%. That means reducing its drag coefficient by 0.008 and also offering 6 additional kilometers of autonomy. They have already applied for the patent in South Korea and the United States and could continue improving it to install it in future models.

Happy drivers
