BYD Super DM Technology – Intelligent Dual-Mode Hybrid System
Efficient, Powerful, and Eco-Friendly PHEV Innovation from BYD
What Is Super DM Technology?
BYD Super DM Technology is an innovative, electric-first plug-in hybrid system exclusively developed by BYD. It integrates a high-power electric motor and large-capacity battery as the primary propulsion source, with the engine engaging only when needed. This architecture ensures exceptional energy efficiency, ultra-low fuel consumption, dynamic responsiveness, and a quiet, smooth ride — delivering a profoundly eco-friendly and practical driving experience
Super DM Benefits and Key Features
Energy Efficiency & Extended Range
- The system leverages the Xiaoyun 1.5L hybrid engine, which achieves a thermal efficiency of 43.04%, with an operational efficiency zone reaching 80%, resulting in impressively low fuel consumption — as low as 6L per 100km
- Coupled with an electric motor with 97% efficiency, it enables a pure-electric range of 70 km and a combined driving range exceeding 1,000 km, ensuring flexibility under diverse conditions
Performance & Responsiveness
The system delivers up to 238 kW of total system power, facilitating exhilarating and agile performance comparable to that of a 2.0T engine .
The EV motor responds with exceptional precision, boasting a 10 ms response time, allowing seamless acceleration and control
Quiet & Comfortable Driving
The electric-centric architecture minimizes noise and vibrations, providing a tranquil, pure EV-like feel — whether cruising in the city or on the highway .
Seamless transitions between drive modes ensure an exceptionally smooth ride and effortless gear shifts
Charging Faster
Experience the convenience of fast DC charging with Super DM Technology.You could charge your battery from SOC 30% to 80% in just 35 minutes. There is also an AC option for charging at home.
V2L： Pratical & Fun
BYD DM models, with VtoL, can be transformed into a mobile power bank, providing power for a wide range of electrical appliances, from computers and gaming consoles, open-air cinemas, to kettles and barbecues.

A Large Capacity Blade Battery
BYD Super DM Technology uses a tailor-made version ofthe highly acclaimed Blade Battery. These bespoke Blade Batteries for the hybrid platformhave power capacities ranging from 18.3 kWh, achieving a pure-electric range from 70km. lt offers multiple benefits such as the following.
3 Power Supply Modes
- Enjoy quiet journeys with excellent ride comfort, and fast responsive acceleration that is synonymous with pure-electric driving.
- Regenerative braking harvests energy and increases the range.
- In Pure EV Mode, the wheels are 100% driven by the electric motor for an all-electric drive experience, with the Xiaoyun engine on standby.
- When the battery power falls below the user-set SOC value, the engine will automatically engage for range extension.
- While the Xiaoyun engine acts as a generator charging the battery, the wheels are driven by the electric motor, making HEV mode the ideal companion for extending range.
- The wheels are driven by both the electric motor and the Xiaoyun engine.
- This mode produces fast responsive acceleration in situations such as overtaking on highways, providing high power performance.
- Moreover, for high-speed cruising at low SOC, wheels are 100% driven by the Xiaoyun engine, reducing fuel consumption combined with economical and efficient power output.
