  • AAS technology controls the air flow and turbulence depending on the car’s speed
  • Installed between the front bumper and front wheels, AAS becomes operational at speeds over 50 mph when the aerodynamic resistance becomes greater than the air resistance, and is stored again at 45 mph
  • The AAS aerodynamic enhancements increase downforce, which improves vehicle traction and high-speed stability
  • AAS technology tested on GV60 has shown a reduction in drag coefficient of 2.8 percent, resulting in an expected 3.7 miles of additional range

Frankfurt, Germany, 23 January 2024: Genesis has today unveiled a new innovative ‘Active Air Skirt’ (AAS) technology, designed to minimise aerodynamic resistance generated when driving at higher speeds, effectively improving the driving range and driving stability of electric cars.

AAS is a technology that controls the flow of air entering through the lower part of the bumper, as well as the turbulence generated around the vehicle wheels, by operating variably according to the car’s speed.

Exploring ways to reduce the drag coefficient (Cd), which is the resistance coefficient of the air acting against the car’s motion, has many benefits.  Aerodynamic performance has a significant impact not only on power performance, but also on driving stability and wind noise.  In the era of electrification, a feature which can improve the driving range from a single charge is highly desirable.

AAS is installed between the front bumper and the front wheels and is hidden, only becoming operational at speeds over 50 mph when the aerodynamic resistance becomes greater than the rolling resistance. It is then stored again at 45 mph, helping to avoid the technology being deployed too frequently. Thanks to the application of rubber material on the lower part of the skirts, which ensures durability and reduces the risk of damage from external objects while driving at high speeds. AAS can operate at speeds over 125 mph, where allowed.

The AAS only covers the front part of the tyres, allowing it to work more effectively with Genesis’ E-GMP (Electric Global Modular Platform), which has a flat floor, improving aerodynamic performance. It also functions to enhance downforce, thereby improving traction and high-speed stability.

Through testing AAS installed on GV60, Genesis has found that the drag coefficient (Cd) has been reduced by 0.008, improving drag by 2.8 percent, equating to an expected additional range improvement of about 3.7 miles. The company has applied for related patents in South Korea and the United States, and plan to consider mass production after further durability and performance tests.

“This technology is expected to have a greater effect on models such as SUVs where it is difficult to improve aerodynamic performance,” said Sun Hyung Cho, Vice President and Head of Mobility Body Development Group at Hyundai Motor Group. “We will continue to strive to improve the driving performance and stability of electric vehicles through improvements in aerodynamics.”

Genesis Active Air Skirt technology is currently in development and any plans for production will be announced at a later date.
