What brand is the engine of Li Auto?
1 Answers
Li ONE is equipped with the DAM12TD range-extender engine supplied by Dongan Power, which is a three-cylinder engine with a displacement of 1.2T, a maximum power of 96kW, and 131 horsepower. This is the first new energy vehicle engine developed by Harbin Dongan Power, a wholly-owned subsidiary of Changan Automobile, mainly producing engines, transmissions, and components. The engine of Li ONE is used as a range extender for generating electricity and does not directly drive the vehicle. The electric four-wheel drive system consists of dual motors at the front and rear. The front motor is provided by United Electronic, the rear motor by BorgWarner, the electric drive control system by Inovance Technology, and the power battery by CATL. Therefore, the computer can keep the engine running in the most efficient speed range most of the time, achieving extremely low fuel consumption. Due to the compact size of the 1.2T engine, the vehicle's space utilization is very reasonable. Both the front motor and the range extender are placed in front of the front axle, leaving ample space for the battery. The four-wheel drive system composed of two motors has a maximum power of 240kW and a maximum torque of 530 N·m, with a 0-100 km/h acceleration time of less than 6.5 seconds. The power mode of Li ONE's range extender matches an engine with an electric motor, where the wheels are driven only through electrical transmission, and the engine serves as a range extender to convert thermal energy into electrical energy to power the motor. In urban conditions, the most economical pure electric mode is used, while on highways, the engine will inevitably intervene, and the low-speed cruising condition also helps the engine operate in its most efficient range, achieving a balance between power and fuel economy. The biggest advantage of range-extender models is that their weight is lighter than that of general new energy vehicles of the same size. Li ONE uses a ternary lithium battery with a capacity of 40.6 kWh and an available capacity of 37.2 kWh. The small battery reduces the overall vehicle mass, which is very friendly to reducing energy consumption during high-speed driving.
