What is the highway fuel consumption of the BYD Song Plus-DMi?
3 Answers
The highway fuel consumption of the BYD Song Plus-DMi is 7.14 liters per 100 kilometers. The highway fuel consumption is calculated based on hourly fuel consumption, and the calculation method is as follows: fuel consumption per 100 kilometers / 100 * limit speed * 0.8 (the limit speed is the maximum safe speed). Relevant information about vehicle fuel consumption is as follows: 1. Constant speed fuel consumption refers to the fuel economy indicator when the vehicle is driving at a constant speed on a good road surface. Since constant speed driving is a basic operating condition for vehicles on highways, and this type of fuel consumption is easy to measure, it is widely adopted. 2. Road cycle fuel consumption is the fuel economy indicator measured when the vehicle is driven in repeated cycles according to specified speeds and time norms on the road, also known as multi-condition road cycle fuel consumption. In the speed and time norms, each cycle includes various driving conditions, and specifies the gear shifting time, braking and stopping time, as well as the values of driving speed, acceleration, and braking deceleration for each cycle.
I've been driving the BYD Song Plus DM-i for a while now, with an average highway fuel consumption of around 5.5 liters per 100 kilometers, which is quite worry-free. The hybrid system directly drives the vehicle with the engine on highways, avoiding energy loss from the electric motor, naturally resulting in lower fuel consumption. I usually maintain a speed of 100 kilometers per hour, which helps stabilize this fuel efficiency level. If I drive too fast, say over 130 kilometers per hour, fuel consumption can spike to over 6 liters, so controlling speed is crucial. When the battery is sufficiently charged, fuel consumption is even lower because the electric motor can assist with starting and acceleration. I frequently travel long distances for business trips, and the fuel consumption data recorded by the car's app shows a range of 5.2 to 5.8 liters. Factors affecting this include vehicle load and air conditioning usage. Regular maintenance, such as changing the air filter and checking the fuel system, also helps keep fuel consumption at its best. Overall, it's much more economical than pure gasoline cars, making it especially suitable for long-distance driving enthusiasts.
As someone with some knowledge of automotive technology, I find the highway fuel consumption of the BYD Song Plus DM-i quite intriguing. Its hybrid design allows the engine to operate efficiently at high speeds, typically consuming around 5 liters per 100 kilometers, with actual test data mostly ranging between 4.8 to 6.1 liters per 100 kilometers. The reason lies in the system switching to series or parallel mode, reducing energy waste; fuel consumption can increase to slightly over 6 liters when using air conditioning or carrying a full load. Based on my research, the optimal speed range is between 80 to 110 kilometers per hour, beyond which increased wind resistance leads to higher fuel consumption. I recommend that beginners check tire pressure and maintain it at around 2.5 bar to ensure transmission efficiency. Over long-term use, the battery's state of charge affects fuel consumption; fully charging the battery before highway driving can save some fuel. Compared to similar hybrid vehicles, the Song Plus DM-i's fuel consumption is intelligently controlled, balancing performance and cost effectively.
