What is the difference between DM and DM-i?

[VanMaximus]

Here are the specific differences between BYD's DM-i and DM technologies: 1. Advantages: The DM-i Super Hybrid system is based on a high-capacity battery and high-power electric motor, relying primarily on the electric motor for vehicle propulsion. The gasoline engine mainly functions to charge the battery and only directly drives the wheels when additional power is needed, working in tandem with the electric motor to reduce load. This hybrid technology differs from traditional hybrid systems that depend heavily on the engine, resulting in more effective fuel consumption reduction. 2. Core components: The key component of BYD's DM-i Super Hybrid technology is the newly developed Xiaoyun plug-in hybrid dedicated engine, which comes in two versions – a 1.5L engine mainly used in Qin PLUS and Song PLUS models, and a 1.5T turbocharged engine for larger models like the Tang DM-i. 3. Driving modes: When the battery is sufficiently charged, the DM-i model's electric motor provides adequate power for all road conditions. When battery power is low, the DM-i system automatically determines whether to use electricity or fuel, or a combination of both, based on system operating conditions.
