What is the fuel consumption of BYD DM-i cruising at 120 km/h?
3 Answers
The fuel consumption of BYD DM-i cruising at 120 km/h is 3.8L. Here is additional information: 1. Advantages of BYD DM-i: DM-i has multiple advantages over other hybrid technologies, with its "core philosophy" being electricity as the primary power source and fuel as supplementary. Architecturally, the DM-i Super Hybrid is based on a high-capacity battery and high-power motor. During driving, the vehicle primarily relies on the high-power motor for propulsion, while the gasoline engine mainly functions to charge the battery. It only directly drives the vehicle when additional power is needed, and even then, it works in tandem with the motor to reduce load. This hybrid technology differs from traditional hybrid technologies that rely heavily on the engine, thereby more effectively reducing fuel consumption. 2. BYD DM-i's engine: The core component of BYD's DM-i Super Hybrid technology is the newly developed Xiaoyun plug-in hybrid dedicated engine, which comes in two versions. The 1.5L engine is primarily used in the Qin PLUS and Song PLUS, while the 1.5T turbocharged engine is used in the larger Tang DM-i model. These models feature two key components: the EHS dual motor and the DM-i Super Hybrid dedicated Blade Battery, along with a series of vehicle control systems, engine control systems, motor control systems, and battery management systems, collectively forming the Super Hybrid system. Most importantly, these core components and key technologies are entirely independently developed by BYD.
I've driven the Qin PLUS DM-i on the highway many times, and the fuel consumption is usually around 5.5 liters at a constant speed of 120 km/h. This level is quite surprising, as traditional fuel-powered cars typically consume seven to eight liters on the highway. I've summarized some fuel-saving tips: maintaining proper tire pressure is crucial, avoid setting the air conditioning too low in summer, and don’t overload the trunk with unnecessary items. Once, I took a long trip with my family of five and a fully loaded trunk, and the fuel consumption was only 5.8 liters. The DM-i system really performs steadily on the highway. With fuel prices so high recently, I save a significant amount on gas compared to my colleagues’ fuel-powered cars every time I refuel.
As a hybrid car owner, I specifically recorded the fuel consumption at different speeds. The DM-i consumes approximately 5.3 to 6.0 liters per 100km at 120km/h, depending on the model and road conditions. For example, the Song PLUS DM-i, due to its SUV design with higher aerodynamic drag, consumes about 0.3 liters more than the Qin PLUS. A detail often overlooked is the battery level: fuel consumption is lower when the battery is fully charged, while in a low battery state, the engine needs to recharge the battery, increasing consumption by about 0.5 liters. Using air conditioning in summer has a minimal impact, generally increasing consumption by only 0.2 liters. For highway driving, it's recommended to use the intelligent battery conservation mode, as the system automatically balances energy consumption for optimal efficiency.
