P2 Hybrid Architecture

In order to support the transition to cleaner and more efficient vehicles, BorgWarner offers its P2 module for hybrid electric vehicles (HEVs). The company’s highly flexible technology facilitates fast-to-market hybridization by enabling pure electric driving as well as hybrid functionalities such as stop/start, regenerative braking and supplemental electric propulsion. By uniting all required components in a compact package, BorgWarner’s advanced solution can easily be implemented in existing drivetrains, enabling high degrees of existing capital utilization and hybrid volume flexibility for automakers. Furthermore, both configurations of the company’s P2 module provide significant CO2 emission reductions with low added costs compared to other hybrid architectures.


P2 On-Axis Drive Module

BorgWarner’s P2 module converts a combustion-powered vehicle into a hybrid without changing the engine or transmission. That means automakers can easily expand their vehicle portfolio with less investment and more flexibility. Placed between the engine and transmission, the highly efficient P2 module combines a 48V electric traction motor, engine disconnect clutch, launch device and dual mass flywheel into a compact package nested inside the motor.

P2 Off-Axis Drive Module

The off-axis configuration places the electric motor parallel to the main axis for an even more compact axial package, minimizing changes necessary to implement with existing engines and transmissions. Torque is transferred via a highly efficient and durable chain. This design offers compatibility with manual, automatic and dual-clutch transmissions and addresses the tight packaging of modern drivetrains.
