阿维塔公布风洞测试直播结果：低风阻状态下风阻系数为0.217左右，与官方宣传的0.21相差不大

Core Viewpoint - Avita conducted a live wind tunnel test for the Avita 12, addressing controversies regarding its drag coefficient, with results presented by industry experts and verified by a notary [1]. Group 1: Testing Details - The wind tunnel test took place at the China Automotive Engineering Research Institute, featuring six different test conditions [1]. - The first three test conditions showed drag coefficients of 0.2172 at 160 KPH, 0.2175 at 120 KPH, and 0.2327 with sport wheels at 120 KPH [2]. - The latter three conditions resulted in drag coefficients of 0.2509 with standard mirrors and raised air suspension, 0.2741 with an active grille, and 0.2973 with a 5° vehicle offset, all at 120 KPH [3]. Group 2: Expert Insights - The test utilized a real production vehicle to simulate various real-world scenarios, with the results for conditions one and two closely aligning with the advertised coefficient of 0.21 [3]. - Experts noted that minor changes in vehicle status and testing environments significantly impact drag coefficient results, highlighting the lack of a unified national standard for measuring drag coefficients [3].
