Differences Between BYD Hybrid and Honda Hybrid?
2 Answers
BYD's DM-i hybrid is a plug-in hybrid, while Honda's IMMD hybrid is a gasoline-electric hybrid. Here are the specific details: 1. Hybrid Combination: BYD's DM-i hybrid offers more diverse combination forms and stronger adaptability. Depending on the power of the drive motor, the EHS system can be divided into three types: EHS132, EHS145, and EHS160. 2. Permanent Magnet Synchronous Motor: Both BYD's DM-i hybrid and Honda's IMMD hybrid are equipped with a permanent magnet synchronous motor, which consumes less energy compared to an AC asynchronous motor. The motor power of the two systems is very similar, with the DM-i hybrid at 132 kW and 316 Nm, and the IMMD hybrid at 135 kW and 315 Nm. Such motor configurations balance both power and fuel efficiency.
I've test-driven both cars, and the biggest difference between BYD's hybrid and Honda's hybrid lies in the driving logic. BYD's DM-i primarily relies on electric motor drive, with the engine acting as a high-end generator—80% of the time it runs purely on electricity. Honda's i-MMD also mainly uses electric motor drive, but the engine directly intervenes at high speeds, making the entire system work like a well-coordinated duet. Additionally, BYD must be plugged in to charge, with a larger battery capacity allowing for up to 110 km of pure electric range, while Honda basically cannot be charged and relies solely on kinetic energy recovery, managing only a few kilometers at best on pure electric power. In daily driving, BYD offers better low-speed quietness, making it more suitable for urban commuters.
