Di Yi Cai Jing·2025-08-05 11:05Core Viewpoint - The collision test involving a 2.61-ton SUV and an 8-ton truck has raised significant concerns regarding the safety and design of the truck, particularly focusing on the locking mechanism of the truck's cabin and the test conditions [1][6][8]. 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][4]. - The truck involved was a second-hand Dongfeng Liuqi M3, which had been modified for the test, including weight adjustments and the installation of an autonomous driving system [8][9]. - The test speed was noted to be higher than conventional standards, 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 [8][9]. 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 system being more reliable but costlier [3][4]. - If the locking mechanism is not engaged properly before a collision, the cabin can detach from the chassis, which raises questions about the truck's structural integrity [4][5]. - The test's outcome, where the truck's cabin appeared to detach, suggests that the locking mechanism may not have been engaged, which is atypical for such vehicles [4][5]. Group 3: Industry Reactions and Implications - Dongfeng Liuqi, the manufacturer of the truck, has expressed concerns over the test's execution and the subsequent public perception, emphasizing the need for transparency in the testing process [1][13]. - Li Auto's recent statements indicate a desire to distance itself from the controversy, acknowledging the unintended consequences of the test on Dongfeng Liuqi's reputation [14]. - The incident highlights the ongoing challenges in the commercial vehicle sector regarding safety standards and public trust, especially in the context of competitive marketing strategies [12][14].
