奇瑞高管称：瞬间刹停违反物理学

Core Viewpoint - The discussion around vehicle safety and braking performance highlights the limitations of instantaneous stopping in high-speed scenarios, emphasizing the importance of vehicle control and braking physics [1][2][4]. Group 1: Vehicle Safety and Braking Performance - Chery's executive vice president, Li Xueyong, stated that a vehicle cannot stop instantly at high speeds due to physical principles, particularly when traveling at 120 km/h, where emergency braking can only reduce speed to approximately 80 km/h [1]. - Li emphasized that in emergency situations, vehicle handling, steering, and power are critical for safety, indicating that effective control and gradual deceleration are essential [2]. - The braking process follows Newton's laws and energy conservation principles, where the braking force must overcome the vehicle's kinetic energy, and the maximum deceleration is limited by tire grip, typically between 0.9g and 1.2g [4].
