When we talk about BYD's DM technology, DMP and DMI are undoubtedly the two that have attracted the most attention. Although both belong to BYD's dual-mode hybrid system, they have significant differences in terms of power, technology, and driving experience.
First of all, in terms of power, DMP adopts 2The 0T turbocharged engine has a maximum power of 192 hp and a torque of 320 Nm. This makes DMP-equipped models appear more dynamic during acceleration and driving, providing the driver with more direct driving feedback. The DMI is equipped with 1The 5T engine, although it has a smaller displacement, uses Miller cycle technology, which has higher thermal efficiency and lower fuel consumption. For those consumers who are concerned about fuel economy, DMI is undoubtedly a better choice.
On a technical level, DMP 2Although the 0t engine is superior in data, the technology is relatively traditional. And the DMI's 1The 5T engine uses more advanced technology, such as the Miller cycle, which further reduces fuel consumption while maintaining power. The application of this technology makes the DMI system achieve a relatively perfect balance in terms of fuel economy and power output.
As for the transmission, the DMP is equipped with a conventional six-speed wet dual-clutch transmission. This gearbox has certain advantages in terms of shift speed and smoothness, but there is still a certain amount of frustration at low speeds. The DMI is equipped with an E-CVT continuously variable transmission, which performs better in terms of smooth shifting and fuel economy. Especially in city driving, DMI's e-CVT transmission is more suitable for the driver's needs.
In terms of motor configuration, the DMI system adopts a front-mounted single motor, which is divided into two versions: 145kW and 160kW. This allows for more direct dynamic feedback from the vehicle during both start-up and acceleration. DMP, on the other hand, has more options, with two front and rear (250kW 180kW) dual-motor models in addition to a 180kW rear-mounted single-motor model. This configuration makes DMP more selective in terms of power output and driving experience.
Finally, in terms of driving mode, all DMP models are four-wheel drive models, which undoubtedly increases their passability and driving stability in complex road conditions. The DMI, on the other hand, is a two-wheel drive model that is more suitable for driving in the city and on flatter roads.
In general, although BYD's DMP and DMI represent BYD's leading position in hybrid technology in terms of technology, they have their own unique characteristics and advantages in actual use. For those consumers who pursue driving passion and have higher requirements for power, DMP is undoubtedly a better choice; DMI is a more suitable option for consumers who are more concerned about fuel economy and want a more comfortable and smooth experience when driving in the city. Whether it is DMP or DMI, they represent BYD's continuous progress and innovation in hybrid technology, and also bring us a more diverse and personalized driving experience.
