Di Yi Cai Jing·2025-08-05 09:25Core Viewpoint - The collision test involving a 2.61-ton SUV and an 8-ton truck has raised significant concerns regarding the safety and structural integrity of the truck, particularly focusing on the locking mechanism of the truck's cabin and the test conditions used [1][2][3]. Group 1: Collision Test Details - The collision test was conducted by Li Auto and China Automotive Research, but many details remain undisclosed, leading to skepticism about the validity of the test [1][3]. - The truck involved was a second-hand Dongfeng Liuqi M3, which may have had maintenance issues affecting the test results [5]. - The test speed was noted to be unusually high, with the SUV traveling at 60±2 km/h and the truck at 40±2 km/h, resulting in a relative speed of 100 km/h, exceeding conventional standards for commercial vehicle testing [5][6]. Group 2: Technical Aspects of the Truck - The truck's cabin is designed with a locking mechanism that can be either mechanical or hydraulic, with the hydraulic version being used in the M3 model [2][3]. - If the hydraulic lock is not properly engaged, even minor impacts can cause the cabin to detach from the chassis, which raises questions about the truck's design and safety features [3][4]. - The test's focus on extreme conditions is not standard for commercial vehicle safety assessments, which typically involve different parameters [6][7]. Group 3: Industry Implications - The incident has sparked a "trust crisis" for Dongfeng Liuqi, a well-established brand in the commercial vehicle sector, which has been in operation for nearly 35 years [1][9]. - The marketing strategies for commercial vehicles differ significantly from passenger vehicles, with less emphasis on dramatic safety tests, which may affect public perception [8][9]. - Li Auto's recent statements indicate a desire to distance itself from the controversy while acknowledging the impact on Dongfeng Liuqi's reputation [9].
