BYD India has unveiled its DM-i (Dual Mode Intelligent) plug-in hybrid technology in the country, marking the introduction of the company's globally established system. This technology is expected to support BYD's future product plans in India and boasts a claimed combined driving range exceeding 1,200 kilometres.
Electric-First Approach
Unlike conventional hybrid systems that rely primarily on the petrol engine, BYD's DM-i adopts an electric-first approach. Under most driving conditions, the vehicle operates using electric power, while the engine engages when additional energy or range is needed. The system combines the efficiency of an electric vehicle with the convenience of a conventional powertrain for longer journeys.
Powertrain and Performance
At the core of the setup is BYD's 1.5-litre Xiaoyun petrol engine, which achieves a thermal efficiency of 43.04 per cent. The powertrain can operate in multiple modes depending on driving requirements:
- EV Mode: The vehicle runs entirely on battery power.
- Series Hybrid Mode: The engine functions as a generator to charge the battery while the electric motor drives the wheels.
- Parallel Hybrid Mode: Under higher loads, the engine directly contributes to propulsion.
BYD claims that DM-i-equipped vehicles can accelerate from 0 to 100 kmph in under 5.5 seconds while delivering fuel consumption of 4.8 litres per 100 km under NEDC test conditions. The company also notes lower noise levels and smoother performance comparable to an electric vehicle.
Blade Battery and Safety
The technology is backed by BYD's Blade Battery, which will be used across DM-i models. Safety, efficiency, and refinement form the key pillars of the new hybrid system, according to the company.
Global Experience
BYD's experience in the plug-in hybrid segment dates back to 2008, when it introduced the F3DM, described as the world's first mass-produced plug-in hybrid vehicle. Since then, BYD has sold more than 8 million plug-in hybrid vehicles globally and currently holds over 35 per cent of the worldwide PHEV market.
India Strategy
The introduction of DM-i is expected to play an important role in BYD's India strategy. The company recently crossed the 14,000-customer milestone in the country and aims to expand its presence in the growing new energy vehicle segment. With its combination of electric-focused driving, long-distance capability, and hybrid flexibility, DM-i is expected to form a key part of BYD's future portfolio in India.
Mr Rajeev Chauhan, Head of Electric Passenger Vehicles Business at BYD India, 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. With this innovation, we are bringing a new technology to Indian consumers, and also shaping a smarter, more flexible pathway towards sustainable transportation."
