BorgWarner has extended its business with Hycet Transmission Technology Hebei by supplying its triple-clutch P2 drive module and hydraulic control unit for Great Wall’s Haval and WEY brands.
The components are for the claimed world’s first nine speed P2 9HDCT hybrid transmission for the Hycet I-Era 2.0 powertrain. The hybrid transmission has nine gears and a parking lock.

With the electric motor placed directly between the internal combustion engine and the transmission, the on-axis P2 drive module delivers cost-effective hybridisation through its compatibility with existing vehicle platforms.
The has a compact axial and outstanding performance and is capable of integrating up to three clutches, including a disconnecting clutch. This allows the system to decouple from the engine for pure electric driving, enabling the vehicle to always provide sufficient power performance when the engine is not working or in inefficient areas.
The P2 hydraulic control unit adopts a next generation, low leakage design to further improve the efficiency of the hydraulic system. The latest solenoid valve is also designed for optimised clutch and shifting characteristics, resulting in better system efficiency and performance.
With the development of hybrid technology and subsidy policy adjustments, OEMs are exploring more possibilities for energy conservation and emissions reduction for combustion-fueled vehicles, elevating the role of hybrid vehicles. Among various hybrid structures, BorgWarner’s P2 has been widely recognised by car makers as a highly efficient and fast-to-market hybridisation technology.

By GlobalData“We are thrilled to extend our nearly two-decade partnership with Hycet,” said Volker Weng, president & general manager, BorgWarner DriveTrain Systems.
The P2 drive module can be installed directly into the drive shaft for easy integration. The compact design with up to three nested clutches minimises overall length, enabling OEMs to integrate it with a variety of engines and vehicle platforms, including high voltage PHEV, high voltage HEV and 48V systems.
The triple-clutch P2 module integrates the disconnecting clutch, the drive motor and the cooling system, and features a high-performance, low-noise stator delivering 95% peak efficiency.
By using BorgWarner’s award-winning S-wind wire-forming process to create the motor, the P2 drive module produces high power and torque densities in an extremely compact package. The innovative manufacturing process delivers smaller, more powerful high-voltage electric motors on a mass scale and is expected to help drive growth in the hybrid and electric vehicle market.
BorgWarner can also supply electrohydraulic controls for actuating the wet clutches, giving customers the option to choose individual components or a complete system.
The Great Wall hybrid vehicles equipped with the triple-clutch P2 hybrid drive module and hydraulic control unit be mass produced by the end of January 2022.
