What is the fuel consumption of the BYD Tang hybrid?

[VonPiper]

BYD Tang hybrid version has a fuel consumption of 1.8L per 100 kilometers. The following is an introduction about BYD Tang. Electric mode: The BYD Tang DM is equipped with a hybrid power system. During driving, when the battery is sufficiently charged, the engine will not start even if the accelerator is deeply pressed; when the battery level drops, the system enters hybrid mode, and the engine starts to charge the battery. The engine can maintain optimal operating conditions most of the time, achieving the best fuel economy. As a result, the actual tested fuel consumption by the Ministry of Industry and Information Technology is 1.8L per 100 kilometers. Hybrid mode: The hybrid system of BYD Tang starts the engine only when the power battery level drops to 15%. The vehicle switches to hybrid mode, where the engine not only provides power but also charges the battery. With a full tank of fuel and fully charged battery, the HEV hybrid mode consumes 6.3L per 100 kilometers, and the battery level also drops to 27%. Under low battery conditions, the system automatically enters hybrid mode, and when the battery level recovers to above 20%, the system switches to electric drive. The actual tested fuel consumption is 9L per 100 kilometers. With a full tank and low battery, the motor output proportion is relatively low, and the vehicle mainly relies on the engine. The engine continuously operates in both power generation and driving states, resulting in an actual tested fuel consumption of 12.2L per 100 kilometers.

As a seasoned driver who frequently drives hybrid vehicles, I've been driving the BYD Tang DM for almost two years now. The fuel consumption of this car really depends on how you use it. If you charge it daily and drive in the city for commuting, the displayed fuel consumption can be as low as 1.5 liters, with very little actual fuel usage. However, the most realistic scenario is when driving long distances in a depleted battery state. At 120 km/h on the highway, the fuel consumption is around 7 liters, while driving at 60-80 km/h on national roads is the most fuel-efficient, dropping to about 5.8 liters. Once, I drove fully loaded with five people and luggage on mountain roads, with the air conditioning on, and the consumption climbed to 7.5 liters. Battery charge settings are crucial—setting the charge preservation higher reduces engine starts. In winter, using the heater increases fuel consumption by about 1 liter compared to summer, as it relies on the engine for heat. To save fuel, avoid aggressive acceleration and use ECO mode with maximum energy recovery.

I recently switched to the Tang DM-i, and its official claimed fuel consumption of 5.5L per 100km in hybrid mode is quite reliable. During real-world testing in heavy city traffic during rush hours, when the engine needs to both charge the battery and drive the vehicle, fuel consumption can rise to 6.3L. However, in good suburban road conditions, it can drop to as low as 4.8L. The most pleasant surprise is its pure electric range of 110km when fully charged, using no fuel at all, which translates to just 8 cents per kilometer in electricity costs. The hybrid logic of this vehicle is very intelligent – it uses electric power quietly at low speeds, while the engine directly drives the wheels at high speeds, saving about 30% fuel compared to conventional gasoline vehicles. If charging stations are convenient, it's recommended to set the SOC to 25% for automatic switching. If driven purely as a gasoline vehicle, the 53L fuel tank can cover over 800 kilometers.

Last year, I participated in a fuel-saving competition driving the Tang DM. On the highway with air conditioning set at 23 degrees and three adults on board, I found that the most fuel-efficient speed was 90 km/h, consuming only 5.2 liters. Exceeding 110 km/h increased consumption to 6.8 liters. The hybrid advantage is most noticeable in stop-and-go traffic, where the engine shuts off at red lights and the electric motor takes the lead when starting. During maintenance, the technician mentioned that maintaining tire pressure at 2.6 can reduce fuel consumption by 0.3 liters, which I confirmed with Michelin quiet tires. Northern drivers should note that cold starts consume more fuel, but preheating the car remotely with the air conditioning can help. The battery located in the middle of the chassis makes cornering more stable than the fuel version. When the battery is low, the engine noise is slightly noticeable but quieter than the Highlander hybrid.
