The 5th-Gen DM Technology: Bridging the Gap in Emerging Markets

January 8, 2025 • 10 min read • PHEV Technology

While pure electric vehicles dominate headlines in Europe and North America, a different electrification story is unfolding in Latin America. In Brazil and Mexico—BYD's first and third largest international markets—plug-in hybrid electric vehicles (PHEVs) are outselling BEVs by significant margins. The secret? BYD's 5th-generation DM (Dual Mode) intelligent hybrid technology.

Why PHEV Works in Emerging Markets

The transition to electric mobility faces unique challenges in Latin America that PHEVs elegantly solve:

The 5th-Gen DM-i System Explained

BYD's Dual Mode intelligent (DM-i) system represents the most efficient series-parallel hybrid architecture in production:

Electric-First Philosophy

Unlike traditional hybrids that primarily use the engine with electric assist, DM-i is fundamentally an electric vehicle with a range extender. The electric motor provides primary propulsion while the engine operates only when needed—typically for highway cruising or when battery charge is depleted.

Key Components

The Ethanol Advantage in Brazil

Brazil's Song Plus DM-i is flex-fuel capable, running on gasoline, ethanol, or any blend. Since Brazilian ethanol is made from sugarcane—a renewable resource—the vehicle can operate as effectively carbon-neutral when using E100 ethanol in hybrid mode.

Market Performance: 2025 Data

🇧🇷 Brazil - #1 International Market

Brazil leads BYD's global export markets with 77,904 units in H1 2025, with PHEV models like Song Plus DM-i accounting for the majority.

The Transition Strategy

PHEV technology serves as the perfect bridge for consumers and markets making the transition to electrification:

  1. Today: PHEV provides immediate fuel savings with no charging anxiety
  2. As infrastructure grows: Owners naturally charge more, using less fuel
  3. Next vehicle: Comfortable transition to full BEV with established habits

This evolutionary approach—rather than forcing immediate full-electric adoption—respects the economic realities and infrastructure constraints of emerging markets while still delivering substantial environmental and cost benefits.
