BYD Unveils DM-i Plug-In Hybrid Technology in India

BYD India has officially showcased its DM-i (Dual Mode Intelligent) plug-in hybrid technology in the country, signalling the automaker's intent to expand its product portfolio beyond battery electric vehicles. The technology, which the company says will underpin upcoming model launches, places the electric motor as the primary source of propulsion, with the petrol engine acting in a supporting or charging role.

Unlike conventional hybrid systems that prioritise the combustion engine, DM-i's electric-first architecture is designed to cover most urban and daily driving needs on battery power alone. The petrol engine — a 1.5-litre unit with a claimed thermal efficiency of 43.04% — intervenes during high-speed travel, heavy load situations, or to recharge the battery, enabling the system's stated combined range of more than 1,200 km.

The system operates across three modes: a pure EV mode for city driving, a series hybrid mode in which the engine functions solely as a generator, and a parallel mode in which both the engine and electric motor contribute to propulsion simultaneously.

The company traces its hybrid lineage to the BYD F3DM, unveiled at the 2008 Geneva Motor Show and cited as the world's first mass-produced plug-in hybrid vehicle. Since then, BYD states it has sold over 8 million PHEV units globally, claiming a 35% share of the worldwide PHEV market.

In India, BYD currently operates 48 showrooms across 40 cities and reports a cumulative customer base of 14,000. The company has invested over $200 million in two domestic manufacturing facilities covering more than 140,000 square metres. DM-i-equipped models are expected to be announced as part of BYD India's 2026 product roadmap.
