What is the fuel consumption of BYD Song Plus DMI?

[McWalker]

The fuel consumption of BYD Song Plus-DMI is 5L/100KM. The following is a detailed introduction to the BYD Song: 1. Exterior: It features an X-shaped front grille, giving it a sporty appearance. The side profile of the vehicle adopts a hidden A/B/C pillar design. 2. Powertrain: The BYD Song is equipped with a hybrid system consisting of a 1.5T engine and two electric motors, with one motor positioned on the front axle and the other on the rear axle, enabling all-wheel drive functionality. Additionally, the BYD Song has a pure electric range of 70km and can accelerate from 0-100km/h in 4.9 seconds.

Last time I went on a self-driving trip, I specifically tested the fuel consumption of the Song Plus DM-i. Starting from Beijing to Qingdao with a full tank and fully charged battery, covering over 800 kilometers in total, the displayed comprehensive fuel consumption was 3.8L. The most amazing thing about this car is that it actually saves more fuel in traffic jams. I commute 35 kilometers daily in the city using pure electric mode, charging once every three days, and the fuel gauge barely moves. However, when driving on the highway with the engine engaged, the fuel consumption rises to around 5L. If you don't use electricity at all and run in a depleted battery state, the fuel consumption can reach 5.8L, even the gas station attendant praised it for being more fuel-efficient than his Corolla. By the way, using the heater in winter will increase energy consumption, so it's recommended to preheat the battery in advance using the mobile APP.

I've driven 10,000 km in six months since picking up the car and kept detailed records. With its 18 kWh battery, it can run about 110 km on pure electric power, enough for my three-day work commute. In hybrid mode, the displayed fuel consumption fluctuates between 4-5L, with the lowest I've achieved being 3.3L. Here's a little tip: set the battery preservation level no higher than 50%, otherwise the engine will frequently start to charge. A full tank shows a range of over 1,000 km, and in actual testing, with a full tank and full charge, I drove 1,100 km with 8% fuel remaining, exceeding the official range estimate. The fuel tank is 60 liters, and filling it up costs less than 400 yuan at current fuel prices, saving half compared to similar gasoline cars.

Just finished the first maintenance, let me share the real fuel consumption. Three scenarios: pure electric with AC can run about 85 km; hybrid mode in city is 4.3L; cruising at 120 km/h on highway consumes the most fuel, reaching 5.5L. When the battery is low, the engine roars loudly, but fuel consumption remains at 5-6 liters. Special praise for the kinetic energy recovery system—it can recharge during long descents. Once after returning from mountainous areas, the battery level actually increased by 15%. Using fast charging at charging stations takes 40 minutes to reach 80%, while home charging takes 6 hours for a full charge. Monthly electricity cost is 60 yuan, and fuel cost is 200 yuan, saving over 700 yuan compared to driving the CR-V before.

Extreme test attempted: When the battery was at 5%, driving on the highway in forced power reserve mode resulted in a fuel consumption of 6.2L. For normal driving, it's recommended to maintain a 30% battery level, with fuel consumption generally around 4.5L. The battery temperature control system is crucial; after being exposed to the summer sun, turning on the air conditioning causes energy consumption to surge for the first 10 minutes, returning to normal once the battery temperature drops below 35 degrees. The fuel tank design is quite clever, allowing an additional 8 liters to be added after the pump automatically stops, with a tested maximum range of 1200 km. During maintenance, the technician mentioned the car's generator efficiency is 42%, 3 percentage points higher than Toyota's hybrid system.

After researching this DM-i system, the 1.5L naturally aspirated engine achieves a thermal efficiency of 43%, paired with an E-CVT transmission. In daily driving, electric drive accounts for over 80% of operation, with the engine solely responsible for power generation. Actual tests show a city fuel consumption of 4.8L when the battery is depleted, increasing by 0.6L when the air conditioning is on. One detail: during cold starts, the engine runs at high RPMs to warm up, resulting in higher fuel consumption initially, which stabilizes once the coolant temperature reaches 90°C. Tests at -10°C in winter revealed that using seat heating is more energy-efficient than using the heater. The lithium iron phosphate battery is quite durable, with less than 5% degradation over three years.
