- BYD introduces DM 5.0 with major gains in hybrid efficiency and thermal management.
- The Dolphin G DM-i delivers up to 1,040 km combined range with Blade Battery options.
The BYD Dolphin G DM-i was unveiled on June 16 as the first and only plug-in hybrid B-segment hatchback in its region, introducing the latest DM 5.0 Super Hybrid technology. Customer deliveries are expected to begin in late summer. The new model highlights advancements in hybrid efficiency, powertrain integration, and thermal management while expanding the capabilities of plug-in hybrid vehicles. Developed to improve performance and energy utilization, the vehicle combines a dedicated hybrid engine with Blade Battery technology to offer extended driving range and improved electric mobility.
BYD states that DM 5.0 delivers improvements to the EHS electric hybrid system through optimised cooling strategies, transmission design refinements, and the application of ultra-thin silicon steel sheets. The system also features upgraded electronics and electrics, including a world-first three-controller integration for the powertrain domain. This architecture provides increased computing capability and faster signal transmission speeds, enabling more efficient vehicle operation and enhanced coordination among key powertrain functions.
The thermal management system has been designed to improve overall efficiency by regulating temperatures across the battery, passenger cabin, and front compartment. The vehicle adopts the industry's first full-temperature-range thermal-management architecture, integrating technologies such as direct cooling. By maintaining optimal operating temperatures under different conditions, the system supports energy efficiency, battery performance, and passenger comfort while helping the hybrid system operate more effectively across varying environments.
The Dolphin G DM-i introduces a new 1.5-litre gasoline engine developed specifically for Super Hybrid applications. The engine features a higher compression ratio of 16:1 and incorporates intelligent fuel injection, advanced combustion control, split cooling, and variable lubrication technologies. These enhancements are intended to improve efficiency while maintaining performance. The engine generates 95PS of power and works together with the hybrid system to deliver balanced driving characteristics and extended range capabilities.
The vehicle measures 4,160 mm in length and 1,825 mm in width, with a wheelbase of 2,610 mm. Buyers can choose between two Blade Battery configurations. The Active variant uses a 7.42kWh battery that provides a WLTP electric range of 40 km and a combined driving range of 1,020 km. Boost, Comfort, and Sport versions are equipped with an 18.3 kWh battery, increasing electric range to 105 km while extending the combined range to 1,040 km.
