As the first SUV model equipped with DM-i super hybrid technology, the new car adopts the Xiaoyun-PHEV dedicated 1.5L high-efficiency engine matched with the EHS hybrid system, with a comprehensive power of 173kW. The 110km version accelerates from 0 to 100km/h in just 7.9 seconds. The new car is mainly driven by electricity and offers 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 fuel consumption as low as 4.4L/100km when the battery is depleted. The 110KM version, with a battery capacity of 18.3kWh, has an ultra-long range and is more suitable for use as a pure electric vehicle, supporting 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 remaining battery power was 25% (the displayed pure electric range was 16 kilometers), and the system automatically switched to HEV driving mode. By pressing 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 remaining battery power was 15%, the average speed was still 32km/h, and the increased mileage was 17.6 kilometers. At this time, its total pure electric driving mileage had reached 123.1 kilometers, significantly exceeding the officially announced 110km pure electric range. When the battery power of the BYD Song PLUS DM-i 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 to charge. At this time, its pure electric driving mileage had reached 131.1 kilometers, and the average speed throughout the journey was 32km/h.

I've been driving the BYD Song DM for almost a year now. With a full charge and full tank, it can achieve a range of around 1,000 kilometers. I actually tested it on a round trip from Beijing to Xi'an—only needed to charge once and refuel once, mostly highway driving with no issues. The car is quite hassle-free; pure electric mode is sufficient for city driving, and hybrid mode delivers decent fuel efficiency on highways. I've calculated that it saves a significant amount on fuel costs compared to pure gasoline vehicles. Of course, the exact range depends on your driving style. For instance, if I drive steadily at speeds below 100 km/h, both electricity and fuel consumption are low, and the range can approach the official upper limit of 1,100 km. But with aggressive acceleration or frequent AC use, it might drop to around 950 km. Overall, it's reliable for long-distance trips, and I recommend planning charging stops in advance and checking the battery status before long journeys.

Why can't the car key open the door?

The reasons why the car key cannot open the door are: 1. The remote key is out of battery; 2. The car battery is out of power, or there is strong signal interference around; 3. You can use the hidden mechanical key inside the remote key to open the door. If the mechanical key also cannot open the door, it is a door lock malfunction. If the car battery is out of power, the car's sensing system will naturally fail, resulting in malfunction. In this case, the car needs to be recharged. A common issue is the car key battery running out of power, leading to malfunction. Generally, the battery life of a car sensing key is about 2 years. If the battery is dead, the door cannot be opened via sensing. For cars with a one-button start, if the key battery is dead, you can only use the spare key inside the sensing key to open the door.
