What is the fuel consumption of the Song Plus DM-i when the battery is depleted?
4 Answers
Song Plus DM-i's fuel consumption when the battery is depleted is approximately 7.14 liters per 100 kilometers. Overview: Fuel consumption per 100 kilometers refers to the amount of fuel a vehicle consumes when traveling a distance of 100 kilometers at a certain speed on the road. It is a theoretical indicator for vehicles. The fuel consumption per 100 kilometers is a value obtained by manufacturers under objective conditions using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then calculated as the theoretical experimental fuel consumption data for the vehicle model when traveling at specified speeds. Additional Information: Since most vehicles approach their most economical speed at 90 kilometers per hour, the theoretical fuel consumption figures published by most manufacturers are typically the fuel consumption per 100 kilometers at 90 kilometers per hour.
As an ordinary user, I've tried the BYD Song Plus DM-i. Its fuel consumption in charge-sustaining mode is generally around 5 liters per 100 kilometers, and the actual experience is quite worry-free. Once when the battery was low during a long-distance trip, the system automatically switched to the engine's efficient mode, maintaining stable fuel consumption at 5.2 liters throughout the journey, which is 1-2 liters less than traditional gasoline cars. When the battery is low, the engine prioritizes driving the wheels or making small charges to the battery, which is ingeniously designed to avoid energy waste. During driving, I didn't notice any power reduction, and the fuel economy is decent, making it particularly suitable for urban commuting scenarios where you occasionally forget to charge. Personally, I think this plug-in hybrid technology is highly practical, and over long-term use, it saves money by requiring less refueling.
From a technical perspective, the Song Plus DM-i operates its engine within the high-efficiency range during battery depletion, primarily driving directly while also charging. The official claimed depleted fuel consumption is 4.5-5.5L/100km. Based on my experience with similar models, actual driving may slightly exceed this to around 5.3 liters due to factors such as road conditions, system optimization to prevent excessive consumption, and the core principle of coordinated fuel-electric operation to minimize idling. This design is more energy-efficient than pure gasoline engines, offers quick response, and maintains power via the engine when not consuming electricity, with overall reliability being unquestionable.
According to BYD's data, the official fuel consumption of the Song Plus DM-i in charge-sustaining mode is approximately 4.8L/100km. My actual measurements in urban environments averaged slightly over 5L. Test conditions such as load or air conditioning use may slightly increase consumption by around 0.2L, but the results generally align with the advertised figures. In charge-sustaining mode, the system does not rely on battery power, and the engine directly drives the system efficiently, ensuring fuel-saving performance, which has received widespread satisfaction from users. High reliability is a standout feature. For more precise details, it is recommended to refer to the official documentation.
