让马斯克吃瓜的“风阻造假门”，到底谁在说谎？

Core Viewpoint - The controversy surrounding the alleged false wind resistance coefficient of the Avita 12 has concluded, with both parties presenting valid points regarding their respective test results and conditions [1][5][13]. Group 1: Event Overview - The controversy began when a tech blogger, "Zurich Beile Ye," tested the Avita 12's wind resistance coefficient at 0.28Cd, contradicting Avita's claim of 0.21Cd, leading to significant public attention [1][2]. - Avita responded by offering a reward of 5 million yuan to combat negative publicity and conducted a live wind tunnel test, which yielded a coefficient of approximately 0.217Cd [2][3]. - The blogger received a lawyer's letter from Avita demanding the removal of false statements and a public apology, which he partially complied with while still implying that Avita used a prototype vehicle for testing [3][4]. Group 2: Testing Conditions and Results - Both parties' test results were deemed valid but were influenced by different testing conditions: Avita's test used electronic mirrors, air suspension, and low-resistance wheels, while the blogger's test used standard mirrors and a different vehicle configuration [5][6][10]. - The differences in testing conditions highlight the complexity of measuring wind resistance coefficients, which can vary significantly based on vehicle specifications and testing environments [7][18]. Group 3: Industry Implications - The incident underscores the lack of standardized testing protocols in the automotive industry, leading to potential consumer confusion regarding vehicle performance claims [20][23]. - The competitive landscape has intensified, with companies like Tesla setting benchmarks for wind resistance, prompting other manufacturers to engage in similar marketing strategies [25][26]. - The pursuit of lower wind resistance coefficients has led to increased R&D costs and a trend towards homogenized vehicle designs, raising concerns about user experience and safety [26][27].
