BYD DM-i's fuel consumption at 120 km/h cruise speed is 3.8L. Here are some extended details: Advantages of BYD DM-i: DM-i has multiple advantages that lead other hybrid technologies, and its "core philosophy" is to prioritize electricity with fuel as a supplement. In terms of architecture, the DM-i Super Hybrid is based on a high-capacity battery and high-power electric motor, with the vehicle primarily driven by the high-power motor during operation. Main functions: The gasoline engine's primary role is to charge the battery, only directly driving when additional power is needed, and even then, it works in tandem with the electric motor to reduce load. This hybrid technology differs from traditional hybrid technologies that rely heavily on the engine, thus more effectively reducing fuel consumption. 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—a 1.5L engine mainly used in Qin PLUS and Song PLUS, and a 1.5T turbocharged engine used in the larger Tang DM-i model. Key components: The EHS dual motor, 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, together form the super hybrid system. Most importantly, these core components and key technologies are entirely independently developed by BYD.

I've been driving a BYD DM-i car for almost a year for my daily commute, and the fuel consumption is truly impressive. I drive the Song Plus DM-i, mainly for city commuting. If I don't charge frequently, the fuel consumption is around 4 to 5 liters per 100 kilometers. On the highway, it's even more fuel-efficient, dropping below 4 liters, mainly because the system automatically switches to hybrid mode, and the electric part helps save fuel. However, when using air conditioning in hot weather or during cold winters, the fuel consumption rises to around 5 liters due to reduced battery efficiency. My experience is to make the most of the pure electric mode—short city trips of a few dozen kilometers consume no fuel at all, saving a lot of money. Plus, the driving experience is smooth, with no sudden jerks during acceleration like in conventional fuel cars. I recommend regular vehicle maintenance checks to avoid underinflated tires affecting fuel efficiency. Overall, the DM-i is one of the best choices among hybrid cars, offering great value for money and long-term reliability.

I have some research on automotive technology, and BYD's DM-i system is truly innovative. The low fuel consumption is due to its integration of electric and hybrid modes. Official data shows that, for example, the Qin Plus DM-i has a combined fuel consumption of 3.8 to 4.2 liters per 100 kilometers, but my actual road tests indicate it might be around 4 to 5 liters, depending on driving habits. The system automatically allocates work between the engine and the motor, with the engine being more efficient and fuel-saving during high-speed cruising, while relying more on the battery in city traffic jams. Temperature changes or long-term high-load driving can affect the data—for instance, using air conditioning may increase consumption by about 0.5 liters. Technically, the large battery capacity allows for over 50 kilometers of pure electric range, making it very practical for daily commutes. I recommend owners pay attention to charging frequency to avoid excessively low battery levels affecting fuel efficiency. Overall, the DM-i system is ingeniously designed, with stable fuel consumption, making it an eco-friendly and hassle-free choice.

When buying a car, I was particularly concerned about fuel costs, and BYD DM-i really helped me save money. I've been driving it for almost three months, with a combined fuel consumption between 4 to 5 liters per 100 kilometers, nearly half that of traditional gasoline cars. For example, a full tank can easily cover 600 kilometers, saving me several hundred yuan on fuel expenses each month. In winter or during frequent highway driving, the fuel consumption slightly increases to around 5 liters, but on average, it's still very cost-effective. I often use the pure electric mode for short commutes, which is even more economical with zero fuel consumption. I recommend using the app to monitor fuel consumption and optimize driving habits by avoiding aggressive acceleration. Overall, it offers great value for money and is an excellent commuting companion.
