近日，韩国现代汽车集团发布了一项创新技术——主动式导流裙(AAS)技术，旨在提升旗下电动汽车的续航里程和高速行驶性能。该技术在车辆前保险杠后方、靠近前轮的位置部署导流裙，以减少车轮引起的空气湍流。导流裙会在车速超过80公里/小时时自动展开，并在车速低于70公里/小时时自动收起。根据现代汽车的测试，在捷尼赛斯GV60上采用AAS技术后，车辆的空气阻力系数(Cd)降低了0.008,相当于降低了2.8%的风阻。除了降低风阻，现代汽车表示，主动空气导流板技术还能够提供额外的下压力，即使在超过200公里/小时的高速行驶时也能发挥作用。一般来说，许多赛车也会采用类似的空气动力学设计来减少车轮周围的气流紊乱。不过，现代汽车计划将AAS技术应用于多种车型。在电动车市场，任何细微的续航里程提升都至关重要。IT之家注意到，现代Ioniq 6已经采用了主动式空气襟翼、轮毂导流帘、轮拱缩窄器和后扰流板等一系列技术来降低空气阻力系数。目前，AAS技术仍处于研发阶段，现代汽车已在韩国和美国申请了专利。该公司表示，将在完成耐久性和性能测试后“考虑量产”。因此，这项技术最终是否会出现在量产车上，还存在一定的不确定性。

Title: Hyundai Motor Launches Innovative Technology: Active Air Guideline (AAS) Helps Electric Vehicles Double Their Range!
Keywords: Hyundai Motor, Active Air Guideline (AAS), Electric vehicles
News Content: Recently, the Korean Hyundai Motor Group released an innovative technology called Active Air Guideline (AAS) technology, which aims to improve the range and high-speed driving performance of its electric vehicles. The technology deploys a flow guide behind the front bumper of the vehicle, close to the front wheels, to reduce air turbulence caused by the wheels. The flow guide will automatically unfold at speeds above 80 km/h and automatically retract at speeds below 70 km/h. According to Hyundai’s tests, after applying AAS technology to the Jeezo GV60, the vehicle’s drag coefficient (Cd) was reduced by 0.008, equivalent to a reduction of 2.8% in wind resistance. In addition to reducing wind resistance, Hyundai said that the active air guideboard technology can also provide additional downforce, which can be effective even at speeds above 200 km/h. Generally speaking, many racing cars also use similar aerodynamic designs to reduce turbulence around the wheels. However, Hyundai plans to apply AAS technology to various models. In the electric vehicle market, any slight improvement in range is crucial. IT Home noticed that the Hyundai Ioniq 6 has already adopted a series of technologies such as Active Air Wings, Wheel Hub Guide Liners, Wheel Arch Narroweners, and Rear Diffuser to reduce the drag coefficient. At present, AAS technology is still in the research and development stage, and Hyundai has applied for patents in South Korea and the United States. The company said it would “consider mass production” after completing durability and performance testing. Therefore, there is still some uncertainty about whether this technology will eventually appear in mass-produced vehicles.
