Summary: SOUEAST has outlined its C-DM hybrid system ahead of the 2026 SOUEAST Global Technology Experience Day, which will also showcase the Group’s work in smart energy, robotics and autonomous driving. The C-DM hybrid system is applied across SOUEAST’s hybrid lineup, including the S06 DM and S08 DM.
Key engineering takeaway: The C-DM hybrid system incorporates a hybrid-dedicated engine, a dedicated hybrid transmission (DHT), a dedicated hybrid battery and a control management system, and switches between pure electric and hybrid modes. In the S08 DM, a 1.5TD hybrid-dedicated engine with 45.95% thermal efficiency and a stepless electric DHT deliver 255 kW and 525 Nm, while an 18.4 kWh battery gives 89 km of WLTC pure electric range, a combined range of over 800 km and fuel consumption as low as 5.3 L/100 km in charge-depleting mode.
Why it matters: SOUEAST says the C-DM hybrid system coordinates the powertrain and battery management to balance power performance, fuel efficiency and driving range. Pure electric mode helps reduce energy consumption on urban commutes, while hybrid mode offers greater flexibility for long-distance travel with less reliance on charging infrastructure.
As the global automotive industry advances towards electrification and intelligence, technological innovation is creating new possibilities for future mobility. The 2026 SOUEAST Global Technology Experience Day will showcase the Group’s innovations in the fields of new energy and AI, highlighting its commitment to exploring and advancing future technologies. Meanwhile, SOUEAST is working to translate innovation into practical mobility solutions with a continued focus on user needs.
The Group continues to explore the potential of emerging technologies in smart energy, robotics, and autonomous driving. In smart energy, an integrated solar-storage-charging system and Vehicle-to-Grid (V2G) technology will demonstrate how solar power, battery storage, and high-power charging can work with vehicles to enable more efficient and sustainable energy use.
Robotics is also expanding into new applications. AiMOGA’s home companion robot, “AiMOGA,” will make its global debut, with pre-orders opening at the same time. AiMOGA robots are already operating across more than 100 use cases worldwide, with over 3,000 units delivered and operations spanning more than 60 countries and regions. The Group will also unveil its purpose-built, factory-integrated L4 Robotaxi developed for global markets, emphasizing its ongoing efforts to shape future mobility.
With product and user needs in mind, SOUEAST is accelerating the integration of new energy and intelligent technologies into its vehicles.
How The C-DM Hybrid System Works
In the new energy field, SOUEAST has developed its C-DM Hybrid System to meet diverse mobility needs. By coordinating the powertrain and battery management, the system balances power performance, fuel efficiency, and driving range.
The C-DM Hybrid System incorporates a hybrid-dedicated engine, a dedicated hybrid transmission (DHT), a dedicated hybrid battery, and a control management system. It can seamlessly switch between pure electric and hybrid modes to balance power delivery and energy efficiency across different driving scenarios. SOUEAST has applied this technology across its hybrid lineup, including the S06 DM and S08 DM.
S08 DM Power, Range And Driving Modes
The S08 DM, powered by a 1.5TD hybrid-dedicated engine and a stepless electric DHT, delivers a maximum power of 255 kW and maximum torque of 525 N·m, with engine thermal efficiency reaching 45.95%. The model also features an 18.4 kWh high-reliability battery, offering a WLTC pure electric range of 89 km and a combined range of over 800 km. It consumes as little as 5.3 L/100 km of fuel in charge-depleting mode and supports sustained driving at speeds above 180km/h.
Drivers can select the most suitable mode for each scenario. Pure electric mode helps reduce energy consumption during urban commutes, while hybrid mode offers greater flexibility for long-distance travel with less reliance on charging infrastructure.
Guided by its “Travel+” strategy, SOUEAST continues to connect technological innovation with real-world mobility needs, expand its product portfolio, and bring technology into every journey to deliver more efficient, comfortable, and flexible experiences for users worldwide.
C-DM Hybrid System: Frequently Asked Questions
What is the SOUEAST C-DM hybrid system?
The C-DM hybrid system is a SOUEAST hybrid powertrain that incorporates a hybrid-dedicated engine, a dedicated hybrid transmission (DHT), a dedicated hybrid battery and a control management system. It switches between pure electric and hybrid modes, and SOUEAST has applied it across its hybrid lineup, including the S06 DM and S08 DM.
What is a dedicated hybrid transmission (DHT)?
A dedicated hybrid transmission is a gearbox designed from the outset for a hybrid powertrain, integrating one or more electric machines with the mechanical drive so that the engine, the motors or both can drive the wheels. Because the electric machines can handle pulling away and low-speed driving, a DHT typically needs fewer fixed ratios than a conventional automatic. In the S08 DM, SOUEAST pairs a stepless electric DHT with the 1.5TD hybrid-dedicated engine.
What does engine thermal efficiency mean?
Engine thermal efficiency is the share of the chemical energy in the fuel that the engine converts into mechanical work at the crankshaft, with the rest lost mainly as heat in the exhaust and cooling system. Quoted figures for engines generally refer to the most efficient operating point. SOUEAST quotes engine thermal efficiency of 45.95% for the 1.5TD hybrid-dedicated engine in the S08 DM.
What are the SOUEAST S08 DM specifications?
SOUEAST quotes 255 kW maximum power and 525 Nm maximum torque from a 1.5TD hybrid-dedicated engine and a stepless electric DHT, an 18.4 kWh battery, a WLTC pure electric range of 89 km, a combined range of over 800 km, fuel consumption as low as 5.3 L/100 km in charge-depleting mode, and sustained driving at speeds above 180 km/h.
What is charge-depleting mode?
Charge-depleting mode is the operating state of a plug-in hybrid in which the vehicle draws mainly on energy stored in the battery, so the battery state of charge falls over the trip, with the engine assisting when needed. It contrasts with charge-sustaining mode, in which the engine and regeneration hold the battery state of charge roughly level.
