What is the difference between BYD DM-i and EV?
2 Answers
BYD DM-i and EV differ in the following aspects: 1. Different advantages: DM-i has multiple advantages that lead other hybrid technologies, and its "core concept" is to prioritize electricity and use fuel as a supplement. In terms of architecture, the DM-i Super Hybrid is based on a large-capacity battery and high-power motor, relying on the high-power motor to drive the vehicle during operation. 2. Different core technical components: The core components of BYD's DM-i Super Hybrid technology are the newly developed Xiaoyun plug-in hybrid dedicated engines, which come in two different versions—the 1.5L engine is mainly used in the Qin PLUS and Song PLUS, while the 1.5T turbocharged engine is used in the larger Tang DM-i model. 3. Different driving modes: When the DM-i model has sufficient battery power, it operates like a pure electric vehicle, with the motor providing enough power for driving under various road conditions. When the battery is low, the DM-i model autonomously decides whether to use electricity, fuel, or a combination of both based on the system's working conditions.
I think the main differences between BYD's DM-i and EV lie in the powertrain and practical usage. The DM-i is a plug-in hybrid, equipped with both an electric motor and a fuel engine, allowing it to run on either electricity or gasoline. The EV, on the other hand, is a pure electric vehicle powered solely by a battery and motor. With the DM-i, short trips can be powered by electricity, saving money and being eco-friendly, while long trips without charging stations can rely on the engine, eliminating range anxiety. EVs require constant attention to charging, which can be inconvenient without a fixed home charging point. In terms of range, EVs typically offer longer pure electric mileage, but the DM-i has a greater total range due to its gasoline backup. Both provide excellent driving experiences: the DM-i is quiet and fuel-efficient in electric mode, with fuel consumption as low as a few liters per 100 km, while the EV is silent and emission-free throughout. However, the DM-i produces slight noise when the engine kicks in, which isn't an issue with the EV. Overall, the DM-i is more suitable for people like me who frequently travel long distances or in rural areas, offering higher flexibility, while the EV is better suited for urban commuting or areas with well-developed charging infrastructure, eliminating fuel costs.
