Drive Modes
Three different operating modes are used by the two-motor system, which seamlessly switches between the three depending on throttle position, state of battery charge, and other factors.
EV Drive Mode – Active when starting from a stop, during light cruising and acceleration, and when braking. The gasoline engine is off in this mode and is decoupled from the drivetrain to reduce friction.
Hybrid Drive Mode– The electric propulsion motor alone powers the front wheels, with the gasoline engine powering the electric generator motor, which in turn provides power to the battery pack. This either supplements the battery by providing added electrical power to the propulsion motor or charges the battery if needed.
Engine Drive Mode – Under certain conditions, such as when cruising at medium to high speeds, the high-efficiency Atkinson-cycle i-VTEC® gasoline engine provides propulsion via a lock-up clutch that connects the generator motor to the propulsion motor. This effectively sends power directly from the engine to the drive wheels.
