XIAOMI(HK:01810) Sou Hu Cai Jing·2026-01-05 15:22Core Viewpoint - Xiaomi's YU7 vehicle incorporates a safety design strategy known as "wheel detachment for vehicle protection," which aims to enhance passenger safety during collisions by allowing the wheels to detach from the vehicle in certain scenarios [3][5][7]. Group 1: Vehicle Safety Features - The YU7 underwent a 25% small offset collision test at a speed of 64 km/h, demonstrating that the A-pillar remained undamaged and the passenger compartment was intact, with airbags deploying correctly [3]. - In response to public concerns about the wheel detachment during the test, Xiaomi clarified that this design is intentional to prevent wheel intrusion into the passenger cabin, thereby reducing potential injuries [5][7]. - The vehicle's safety structure includes components such as a subframe, upper beam, and aluminum tower top, which work together to minimize impact on the passenger compartment during collisions [5]. Group 2: Historical Context of Safety Design - The concept of "wheel detachment for vehicle protection" was first introduced by Mercedes-Benz in 1959 with the W111 series, which featured a design that allowed the front suspension and wheels to detach during severe frontal collisions [9]. - Other automotive brands, including Volvo, BMW, and Audi, have since adopted and refined similar safety strategies, with Volvo being particularly noted for its advancements in this area [9]. - Despite its long-standing presence in the automotive industry, the concept of wheel detachment remains largely unknown to the general public, highlighting a gap in consumer awareness that Xiaomi aims to bridge [11].
