How is the range of the BYD Song Plus DM-i?

[AubreyLee]

As the first SUV model equipped with the DM-i super hybrid technology, the new vehicle adopts the Xiaoyun plug-in hybrid dedicated 1.5L high-efficiency engine matched with the EHS hybrid system, with a comprehensive power of 173kW. The 110km version can accelerate from 0 to 100km/h in just 7.9s. The new vehicle is mainly driven by electricity and comes in two range versions, with a comprehensive range of up to 1200 kilometers. The 51KM version is equipped with an 8.3kWh DM-i super hybrid dedicated power blade battery, with a low fuel consumption of 4.4L/100km when the battery is depleted. The 110KM version, with a battery capacity of 18.3kWh, offers an ultra-long range, making it more suitable for use as a pure electric vehicle, and supports 18kW DC fast charging. The pure electric range test of the BYD Song PLUS DM-i after a full charge. During the test, the air conditioning was set to 25°C with A/C on, the energy feedback intensity was set to "higher," and the EV+ECO mode was used throughout. At an average speed of about 32km/h, after driving 105.5 kilometers, the battery's remaining charge was 25% (the displayed pure electric range was 16 kilometers remaining), at which point the system automatically switched to HEV driving mode. By pressing and holding the EV mode button for about 2 seconds, the system could be forced to switch back to EV mode to continue driving. After another 0.5 hours of driving, the battery's remaining charge was 15%, the average speed was still 32km/h, and the additional distance covered was 17.6 kilometers. At this point, its total pure electric driving range had reached 123.1 kilometers, significantly exceeding the officially announced 110km pure electric range. When the BYD Song PLUS DM-i's battery level dropped to 10% (the displayed pure electric range was 0 kilometers), the system finally automatically switched to HEV mode, and the engine began to intervene for charging. At this point, its pure electric driving range had reached 131.1 kilometers, with an average speed of 32km/h throughout the journey.

I've been driving the BYD Song Plus DM-i for almost half a year. My daily commute is 30 kilometers one way. The claimed pure electric range is 110 kilometers, but in reality, it can run 95 to 100 kilometers. Charging twice a week is sufficient. In hybrid mode, the fuel consumption is just over 4 liters per 100 kilometers, and a full tank can run over 1,000 kilometers. Last year, I drove 800 kilometers back to my hometown and only needed to refuel once. Driving habits make a big difference—I prefer smooth acceleration. In summer, using air conditioning reduces the range to around 85 kilometers, and it's even worse in cold winters. Overall, I'm very satisfied. It saves a lot on fuel compared to my colleagues' gasoline cars, saving me one or two hundred yuan every month.

As an automotive technology enthusiast, I tested the BYD Song Plus DM-i's range performance: under ideal conditions, the pure electric mode achieves 110 km, but in urban driving, it's realistically 80 to 90 km; with depleted battery, the fuel consumption is 4.2 liters per 100 km, and the total range easily exceeds 1,000 km. The DM-i system is intelligent and efficient, with the engine directly driving to save fuel and perform well at high speeds, while the blade battery maintains stability in low temperatures with minimal energy loss. The drawback is a 15% range drop when running the air conditioning at full load, but overall advantages are significant, and forum owner data consistently supports the high reliability of its range.

My family uses the BYD Song Plus DM-i to take care of the kids. With a pure electric range of 90 kilometers, it's sufficient for daily commutes, and the electricity cost is only about 50 yuan per month. For long-distance trips up to 1200 kilometers, it's worry-free, with a hybrid fuel consumption of 4.5 liters per 100 kilometers—only one stop needed when traveling with kids. The spacious interior and stable range make it reliable, and even in cold weather, the slight range reduction doesn’t affect safety. It's economical and practical.
