中国汽研首次公开直播阿维塔12风洞测试

Core Viewpoint - The live broadcast of the wind resistance coefficient test for the Avita 12 marks a significant milestone in China's automotive industry, showcasing advancements in aerodynamics and the competitive landscape among electric vehicle manufacturers [1][2]. Group 1: Wind Resistance Coefficient Testing - The China Automotive Engineering Research Institute conducted a live broadcast of the wind resistance coefficient test for the Avita 12, which is the first public live stream of such tests in the automotive sector [1]. - The test simulated six different conditions, revealing that at a wind speed of 160 km/h, the Avita 12 achieved a wind resistance coefficient of 0.2172, which slightly increased at 120 km/h [1]. Group 2: Importance of Wind Resistance Coefficient - The wind resistance coefficient is a critical parameter that quantifies the aerodynamic efficiency of vehicles, directly impacting fuel economy, range, stability at high speeds, and noise levels [2]. - A 10% reduction in wind resistance can lead to a fuel savings rate of 1.5% in NEDC comprehensive conditions, highlighting the importance of this metric for electric vehicles [2]. Group 3: Competitive Landscape and Technological Innovations - As competition intensifies in the automotive market, manufacturers are not only competing on price but also on technical parameters such as wind resistance [2]. - The Avita 12 incorporates innovative features like electronic side mirrors, air suspension, a disc-wing front face, hidden radar, and an external active intake grille to reduce wind resistance and enhance user experience [2]. Group 4: Industry Perspectives - Experts emphasize the need for rational evaluation of the pursuit of lower wind resistance coefficients, comparing it to the past focus on acceleration metrics in traditional fuel vehicles [2]. - The willingness to publicly broadcast such tests is seen as a demonstration of courage and capability within the industry, suggesting that optimizing wind resistance should be a key focus for future research and development [2].
