BYD India, a subsidiary of BYD- the world’s No. 1 new energy vehicle manufacturer, has unveiled its globally successful DM-i (Dual Mode Intelligent) technology in the country, marking its entry into the advanced plug-in hybrid segment and expanding its portfolio of sustainable mobility solutions for Indian consumers.
The technology, which is set to be launched soon, is designed to deliver an electric-first driving experience while offering a combined driving range of more than 1,200 km, addressing concerns around charging infrastructure and long-distance travel.
Electric-first approach
Unlike conventional hybrid systems where the petrol engine serves as the primary power source, BYD’s DM-i technology is built around an electric-first philosophy. The vehicle operates primarily on battery power during daily use, while the engine functions as a generator or supports propulsion when required.
BYD India, Head of Electric Passenger Vehicles Business, Rajeev Chauhan, said, “The introduction of DM-i technology marks a pivotal step in our commitment to making sustainable mobility more versatile and accessible for Indian consumers. By enabling electric-first driving for daily use while seamlessly supporting long-distance travel, DM-i addresses some of the most pressing barriers to the adoption of sustainable motoring in India.”
The system intelligently switches between three operating modes — EV mode for pure electric driving, HEV Series mode where the engine generates electricity for the battery while the motor drives the wheels, and HEV Parallel mode where the engine directly assists propulsion during higher power demands.
Backed by global experience
BYD’s DM technology traces its roots to 2008, when the company introduced the world’s first mass-produced plug-in hybrid vehicle, the F3DM, at the Geneva Motor Show.
Since then, BYD has produced more than 8 million plug-in hybrid vehicles globally, making it one of the world’s largest manufacturers in the segment. The company said the technology has evolved through nearly two decades of development supported by a global R&D workforce of more than 120,000 engineers and technology professionals.
At the heart of the DM-i system is BYD’s 1.5-litre Xiaoyun petrol engine, which delivers a thermal efficiency of 43.04%, among the highest in the industry. Working alongside high-speed electric motors, the system is designed to maximise efficiency while ensuring smooth performance and reduced fuel consumption.
India growth plans
BYD said DM-i technology will play a central role in its India strategy in 2026, helping expand its product portfolio and strengthen its position in the New Energy Vehicle (NEV) market.
The company believes the technology creates a bridge between conventional internal combustion vehicles and battery electric vehicles by combining the benefits of electric mobility with the convenience of extended range.
Expanding presence
BYD entered India in 2007 through electric buses and commercial mobility solutions before expanding into the passenger vehicle segment. Its current portfolio includes the BYD SEALION 7, BYD eMAX 7, BYD ATTO 3 and BYD SEAL.
The company said it has served more than 14,000 customers in India and operates 48 showrooms across 40 cities. Its India operations include two manufacturing facilities spanning over 140,000 square metres, backed by investments exceeding $200 million.
A key pillar of BYD’s India strategy is its proprietary Blade Battery technology, which uses lithium iron phosphate (LFP) chemistry to deliver enhanced safety, thermal stability and durability.
With DM-i, BYD is looking to offer Indian consumers a practical alternative that combines electric mobility, long-range capability and lower running costs, while supporting the country’s transition towards cleaner transportation.
