Key highlights
- BYD introduces its DM-i (Dual Mode Intelligent) technology in India
- Electric-first plug-in hybrid system offers a claimed combined range of over 1,200 km
- BYD says the technology is designed to bridge the gap between conventional ICE cars and full EVs
BYD has officially introduced its globally successful DM-i hybrid technology in India, marking a significant step in the company’s expansion strategy beyond pure electric vehicles.
The technology, which stands for Dual Mode Intelligent, is expected to underpin a new generation of BYD models for India and aims to offer the efficiency of an EV with the convenience of a petrol-powered vehicle. According to BYD, vehicles equipped with DM-i technology can deliver a combined driving range of more than 1,200 km.
What exactly is DM-i technology?
Unlike traditional hybrids where the petrol engine does most of the work and the battery merely assists, BYD’s DM-i system follows an electric-first approach.
In everyday driving conditions, the vehicle primarily relies on electric power. The petrol engine either acts as a generator to charge the battery or directly assists propulsion when higher power is required.
This allows the vehicle to operate much like an EV during daily commutes while retaining the flexibility of a conventional fuel-powered car for long-distance travel.
BYD says the system intelligently switches between different operating modes depending on driving conditions and energy requirements.
How DM-i works
|
Mode |
Function |
|
EV Mode |
Vehicle runs entirely on electric power |

HEV Series Mode |
Petrol engine generates electricity while the electric motor drives the wheels |

HEV Parallel Mode |
Engine and electric motor work together for maximum performance |
Efficient 1.5-litre petrol engine at the heart
A key component of the DM-i system is BYD’s 1.5-litre Xiaoyun petrol engine.
The company claims an industry-leading thermal efficiency of 43.04 percent, helping maximise fuel economy while working alongside one or more electric motors.
BYD also highlights six core advantages of the DM-i platform:

What this means for India
The introduction of DM-i signals BYD’s intention to expand beyond its current EV-only passenger vehicle lineup in India.
The company believes the technology can help customers who want the benefits of electric mobility but are not yet ready to fully transition to battery electric vehicles due to charging concerns or long-distance travel requirements.
