What are the differences between BYD Tang DM and DMI?
3 Answers
BYD Tang DM and DMI differences are introduced as follows: 1. Different power: The DM is equipped with a 2.0T engine, with a maximum power of 192 horsepower (141KW) and a maximum torque of 320Nm, while the DMI is equipped with a smaller 1.5T engine, with a maximum power of 139 horsepower (102KW) and a maximum torque of 231Nm. 2. Different performance: Although the DM's 2.0T engine has stronger data, its technology is also more traditional and hasn't been updated for years. The DMI system's latest 1.5T Xiaoyun engine adopts the Miller cycle, with more advanced technology, higher thermal efficiency, and lower fuel consumption. 3. Different transmissions: The DM is equipped with a traditional 6-speed wet dual-clutch transmission, while the DMI is equipped with an E-CVT continuously variable transmission. Just by the names, it can be seen that the former is more passionate, while the latter is smoother. Although both can directly drive the wheels with the engine, the DM is strong direct drive, while the DMI is weak direct drive, relying more on the electric motor.
As a car enthusiast, I particularly enjoy delving into technical details. Having driven both the BYD Tang DM and DMI, the main differences lie in the powertrain design. The DM version emphasizes performance priority, with dual motors working in tandem with the engine to drive the wheels, delivering ultra-fast acceleration—0 to 100 km/h in just over 4 seconds, making it ideal for speed lovers. However, it has higher fuel consumption, averaging over 6 liters in the city, with a pure electric range of around 80 km. The DMI adopts a smarter approach, where the engine only generates electricity and does not directly drive the wheels; the electric motor alone propels the wheels, similar to a range extender. This reduces fuel consumption to just over 2 liters per 100 km, extends the pure electric range to over 100 km, offers faster charging, and comes at a more affordable price. The DMI's E-CVT transmission is exceptionally smooth, reducing jerky movements and making daily driving more comfortable. While the DM is powerful, it feels a bit rough. Both have similar battery sizes, but the DMI enhances overall efficiency through intelligent optimization, saving money and hassle in the long run. I recommend choosing the DMI unless you're a speed fanatic.
I'm an office worker who commutes daily in a hybrid car and have deep experience with both the BYD Tang DM and DMI. The DM's acceleration is indeed fierce, but after driving it for a while, the fuel consumption is too high, averaging 6 to 7 liters per 100 kilometers in city commuting, which puts a lot of pressure on the wallet. In pure electric mode, it can only run 80 kilometers before needing a charge, which is inconvenient. The DMI is much better—the engine basically only generates electricity, and the drive is entirely handled by the motor, so the fuel consumption is just over 2 liters. The pure electric range can exceed 100 kilometers, meaning I hardly use any fuel for daily commutes, and the electricity costs are much cheaper. In terms of price, the DMI has a lower starting price and is more cost-effective after subsidies. The driving experience is also quite different: the DM's power output is abrupt and can easily cause motion sickness, while the DMI is smooth, quiet, and has much better shock absorption. Overall, the DMI is more suitable for everyday use by ordinary people—it's economical and practical.
