* AAS technology controls the turbulence generated during high-speed driving by operating variably depending on the vehicle's speed
* Installed between the front bumper and the front wheels, AAS is hidden during normal operation but operates at speeds over 80 km/h when the aerodynamic resistance becomes greater than the air resistance and is stored again at 70 km/h
* Taking into account the specificity of the E-GMP platform, it is positioned only in front of the tires without completely covering the front end
* Aerodynamic enhancements of the technology increase downforce, which improves vehicle traction and high-speed stability
* As a result of being tested in the GV60, it is expected to reduce the drag coefficient by 2.8 percent and improve the driving range of electric vehicles
AAS is a technology that controls the flow of air entering through the lower part of the bumper and effectively controls the turbulence generated around the vehicle wheels by operating variably according to the vehicle speed during high-speed driving.
In the EV era, competition to secure a better driving range from a single charge has become fierce, making the relationship between vehicles and aerodynamics even more important. Furthermore, aerodynamic performance has a significant impact not only on power performance but also on driving stability and wind noise.
In response, manufacturers are exploring various measures to reduce the coefficient of drag (Cd), which is the resistance coefficient of the air acting in the opposite direction of the vehicle's motion.
AAS is installed between the front bumper and the front wheels of the vehicle and is hidden during normal operation, but it operates at speeds over 80 km/h when the aerodynamic resistance becomes greater than the rolling resistance and is stored again at 70 km/h. The reason for the difference in deployment and storage speeds is to prevent frequent operation in specific speed ranges.
Also, the reason why AAS only covers the front part of the tires without completely covering the front is related to the characteristics of
AAS can also operate at speeds over 200 km/h. This was possible thanks to the application of rubber material on the lower part, which reduces the risk of external objects splashing and damaging while driving at high speeds and ensures durability.
'This technology is expected to have a greater effect on models such as SUVs where it is difficult to improve aerodynamic performance,' said
