What is the highway fuel consumption of the Tang DMI?
3 Answers
The comprehensive fuel consumption of the two versions of the Tang DMI is 5.3L/100km and 5.5L/100km respectively. Here is more information: 1. The versions of the BYD Tang. The BYD Tang family offers fuel-powered, plug-in hybrid, and pure electric versions to choose from. Unlike the Tang DM, which focuses on high performance, the Tang DMI emphasizes low fuel consumption. 2. The powertrain of the Tang DMI. The Tang DMI is equipped with a hybrid system composed of a 1.5T engine and an electric motor. The manufacturer claims that the fastest acceleration from 0 to 100 km/h takes only 8.5 seconds. 3. Battery aspect. The Tang DMI is equipped with BYD's lithium iron phosphate blade battery, offering two pure electric range versions of 52km and 112km.
I've driven my BYD Tang DMi on the highway several times myself, with fuel consumption fluctuating between approximately 7.5 to 9 liters per 100 kilometers. One weekend trip involved a round-trip highway journey of about 400 kilometers with three passengers and some luggage, maintaining a speed around 100 kilometers per hour, and the dashboard showed an average fuel consumption of 7.8 liters. Using ECO mode indeed saves fuel, but if the speed exceeds 120 kilometers per hour, the increased wind resistance raises the fuel consumption to around 9 liters. I also noticed that maintaining tire pressure at the standard value of around 240 kPa is crucial; too high or too low leads to wasted fuel. Not using the air conditioning can save about 0.5 liters. For long trips, I make sure to check the vehicle's weight in advance to avoid overloading, which helps maintain low fuel consumption. Overall, highway driving is more fuel-efficient than city driving, with a full tank capable of covering 700 to 800 kilometers, making it ideal for family trips.
From the perspective of the hybrid system principle, the highway fuel consumption of the Tang DM-i has an official NEDC rating of 7.2 liters per 100 km, but actual driving conditions vary by individual. I personally tested different speed ranges on the highway and found that maintaining speeds between 80-100 km/h yields the lowest fuel consumption, around 7 liters, as the engine directly drives with motor assistance, ensuring high efficiency. However, exceeding 110 km/h increases wind resistance, causing fuel consumption to jump to 8.5-9 liters. Using ACC adaptive cruise control helps reduce sudden deceleration, stabilizing fuel consumption. Additionally, when the battery charge is high, energy can be recovered, resulting in an average of 7.6 liters over 500 km. Compared to gasoline-powered SUVs, which typically consume over 10 liters on highways, the DM-i system demonstrates clear energy-saving advantages. However, aggressive highway driving can still cause fuel consumption fluctuations.
