近400名小米SU7 Ultra车主维权，4.2万元“灵魂”变装饰

Core Viewpoint - Xiaomi's automotive division is facing significant backlash due to discrepancies between the advertised features of the SU7 Ultra model and the actual product delivered to customers, leading to a trust crisis in the high-end market [1][5][12]. Group 1: Product Features and Customer Expectations - The SU7 Ultra's carbon fiber hood, priced at 42,000 yuan, was marketed as a "complete replica of the prototype car's aerodynamic design," but customers found it to be structurally similar to a standard aluminum hood, lacking promised features [1][3]. - Customers expressed dissatisfaction as Xiaomi did not consult them before changing the specifications and failed to provide adequate compensation, leading to demands for order cancellations and refunds [3][14]. - Xiaomi's apology acknowledged "unclear information expression" and offered two options: switch to an aluminum hood with a 30-40 week wait or receive 20,000 points (approximately 2,000 yuan), which many customers deemed insufficient [3][14]. Group 2: Technical and Engineering Challenges - The complexity of producing the advertised dual-channel airflow design may have contributed to the failure to deliver on promises, as it requires significant modifications to the vehicle's thermal management system [5][9]. - The carbon fiber hood's manufacturing process is labor-intensive, and while it theoretically offers weight reduction, the actual design choices led to minimal weight savings, raising questions about its value [6][10]. - The introduction of decorative openings in the hood, intended to replicate the prototype's appearance, ultimately increased material usage and negated potential weight benefits [6][7]. Group 3: Marketing and Consumer Trust - Xiaomi's marketing strategy prioritized aesthetic appeal over functional performance, resulting in a product that did not meet consumer expectations for high-performance features [12][13]. - The company's decision to limit the vehicle's horsepower from 1,500 to 900 unless specific track performance criteria were met further alienated customers, leading to accusations of "false promises" [13][16]. - As consumer dissatisfaction grows, there are indications of potential legal action against Xiaomi for misleading advertising practices, which could have significant implications for the company's reputation and financial liability [16].
