What is the actual measured fuel consumption of the Song Plus DM-i?
4 Answers
The actual tested fuel consumption value of the BYD Song Plus DM-i under comprehensive road conditions is 4.08 liters per 100 kilometers. Tested road conditions: Driving in urban areas, including city roads (approximately 40%), urban expressways (approximately 50%), and highways (approximately 10%). Tested driving mode: Using HEV+ECO mode for driving, with 3 adults in the car. Air conditioning set at 25 degrees, two levels of fan speed, normal use of entertainment devices and mobile phone charging. In congested sections, closely following the car in front to prevent other vehicles from cutting in. On expressways and highways, driving according to speed limits: maintaining speeds in the 70s km/h on roads with an 80 km/h limit, and speeds in the 110s km/h on roads with a 120 km/h limit.
I've been driving the BYD Song Plus DM-i for several months now. During daily urban commuting, the fuel consumption is about 4.5L/100km when the battery is depleted, and it may rise to around 5.8L on highways, which is quite fuel-efficient. It largely depends on your driving habits—for instance, I maintain low figures by gently accelerating and minimizing braking. However, consumption increases in traffic jams or when speeding. The pure electric mode can cover over 80km, and charging two to three times a week means hardly any refueling is needed, making it significantly cheaper than pure gasoline cars. Actual tests show combined fuel and electricity costs of just over 0.1 yuan per kilometer, half the cost of my colleagues' gasoline cars. Even occasional long trips with refueling are hassle-free. I highly recommend using EV mode more often—it's both economical and eco-friendly. On weekends, taking the family out has never caused range anxiety, and the spacious trunk is a huge plus for storage.
As a hybrid vehicle enthusiast, let me discuss the key factors affecting fuel consumption. The Song Plus DM-i's engine and motor work in synergy, with actual measured fuel consumption ranging between 4 to 6L/100km when the battery is depleted, mainly depending on remaining battery charge, road conditions, and driving style. For example, in urban traffic congestion, the system prioritizes electric power, resulting in lower fuel consumption; while maintaining constant speed on highways allows the engine to directly drive with high efficiency, potentially achieving around 4L. Tests show that running the air conditioning at full blast or during cold winter temperatures may slightly increase fuel consumption by about 0.5L, with pure electric range realistically reaching approximately 90km. It's recommended to check tire pressure and perform regular maintenance for optimization. My data logging app shows a comprehensive average of 4.8L, demonstrating significant advantages compared to traditional SUVs' 8-10L. Paying attention to powertrain temperature can reduce energy loss, and real-world tests confirm this vehicle offers exceptional value for money.
From a cost-saving perspective, driving the Song Plus DM-i in charge-sustaining mode yields a tested fuel consumption of 4.2L/100km. At current fuel prices, this translates to just 30-40 cents per kilometer. Covering 10,000 kilometers saves two to three thousand yuan compared to a pure gasoline vehicle, and with cheap electricity costs, it's incredibly economical. On highways, consumption rises slightly to 5L, but costs remain low. For short trips within the 100km pure electric range, fuel consumption is nearly zero, and using air conditioning doesn't hurt the wallet. Monthly savings can add up to several hundred yuan. Insurance and taxes for this vehicle are also low, making overall maintenance costs lightweight, and it pays for itself in the long run. Tested data is stable with minimal fluctuations—worth it.
