Hybrid Transmission Modes of Operation

WARNING: This page is about a different variant/trim than selected.

Single Motor Electric (EV): Single motor EV operation is used when lower torque is required. This includes reverse gear. The Internal Combustion Engine (ICE) is OFF. The high range clutch is open and the low range clutch is closed. Drive motor B (2) provides torque through the planetary gear set to the wheels.
Low Mode: Low mode is used for forward propulsion at lower vehicle speeds. The Internal Combustion Engine (ICE) is ON. Drive motor A (1) and drive motor B (2) are ON. The low range clutch (C1) is closed and the high range clutch (C2) is open. Drive motor A (1) is generating to charge the rechargeable energy storage system (RESS). The ICE and drive motor B (2) provides torque through the planetary gear sets to the wheels.
Fixed Ratio Mode: Fixed ratio mode is used for forward propulsion at mid-range vehicle speeds. The Internal Combustion Engine (ICE) is ON. The ICE provides power through the planetary gear set to the wheels. Drive motor A (1) and drive motor B (2) are ON. The low range clutch (C1) is closed and the high range clutch (C2) is closed. Drive motor B (2) can perform regeneration to charge the RESS in low torque demands or provide torque through the planetary gear set to the wheels in high torque demands.
High Mode: High mode is used for forward propulsion at higher vehicle speeds. The Internal Combustion Engine (ICE) is ON. The ICE provides power through the planetary gear set to the wheels. Drive motor A (1) and drive motor B (2) are ON. The low range clutch (C1) is open and the high range clutch (C2) is closed. Both drive motor A (1) and drive motor B (2) can either operate in regeneration mode to charge the RESS or provide power to the wheels.
