What is the long-distance fuel consumption of the BYD Tang DM?
2 Answers
The long-distance fuel consumption of the BYD Tang DM is generally around 8 liters per 100 kilometers. Below is some extended information on advanced battery conservation techniques for the BYD Tang DM: Speeding: If the speed exceeds 140 km/h, the engine load is high, so it generally won't charge the battery. Therefore, setting a higher speed won't help, and the battery level might even drop in hybrid economy mode. Uphill driving: For example, when driving into Tibet, where the altitude continuously rises, the engine load will also be relatively high, leaving no extra power to charge the battery. In this case, the battery level won't increase. There are ways to conserve battery power, but note that on roads with alternating uphill and downhill sections, battery conservation isn't necessary as the battery will recharge during downhill driving. If the battery level is too low, you can use sand mode to increase engine speed and reduce vehicle speed, keeping the engine at around 2000 RPM. Traffic congestion: In urban traffic jams, using hybrid economy mode is ineffective, especially in summer with the air conditioning on, as the battery level will drop quickly. To conserve battery power, you can switch to hybrid snow mode, where the engine charges the battery while idling. Alternatively, using sand mode at around 2200 RPM for low-speed driving will result in higher short-term fuel consumption and a less comfortable driving experience, but it will recharge the battery very quickly.
I've taken my BYD Tang DM on several long-distance trips, with fuel consumption typically between 7 to 8 liters per 100 kilometers, depending on driving conditions. Last time I drove from Beijing to Shanghai, mainly on highways with cruise control set at around 110 km/h, the fuel consumption stabilized at about 7.5 liters. If I drove faster, exceeding 120 km/h, the consumption would rise above 8 liters. When the battery is low, it mainly relies on the gasoline engine, and the fuel consumption is higher than the official claims. However, maintaining a steady speed and avoiding heavy acceleration can still save fuel. I recommend checking tire pressure and oil condition before long trips to improve efficiency; turning off unnecessary electrical appliances like high-power air conditioning on highways can save about 0.5 liters. The car has ample space, comfortably accommodating five people with luggage, offering great value for money, making it ideal for family trips.
