BYD Tang DM Highway Fuel Consumption?

[Dale]

BYD Tang DM's fuel consumption on highways is generally around 8L/100km. Below is extended information on advanced battery preservation techniques for the BYD Tang DM: 1. Speeding: If the speed exceeds 140km/h, the engine load becomes high, so it generally won't charge the battery. Therefore, setting a higher value won't help, and the battery level might even drop in hybrid eco mode. 2. Uphill Driving: For example, when entering Tibet with continuously rising altitude, the engine load will be relatively high, leaving no extra power for charging. In this case, the battery level won't increase. There are ways to preserve battery, but note that for road conditions with alternating uphill and downhill sections (like mountain passes), battery preservation isn't necessary as the battery will recharge during downhill. If the battery level is too low, you can use Sand Mode to increase engine speed to around 2000 RPM while reducing vehicle speed. 3. Traffic Jams: In urban traffic jams, using hybrid eco mode is ineffective. With air conditioning on during summer, the battery level will drop quickly. To preserve battery in this situation, you can switch to hybrid Snow Mode where the engine charges the battery at idle. Alternatively, using Sand Mode at around 2200 RPM for low-speed driving will result in higher short-term fuel consumption and poorer driving experience, but it recharges the battery very quickly.
