2.4L-T HEV on the RX500h features a front unit integrating a 2.4L turbocharged engine, motor, a 6-speed automatic transmission and an eAxle with a built-in high-output motor driving the rear wheels, and a high-power bipolar nickel-metal hydride battery under the rear seats. This system harnesses the powerful torque of the turbocharged engine and the quick response of the motor torque to provide a direct, torque-filled, and continuous acceleration feel. In addition, the 6-speed AT uses a wet start clutch in place of a torque converter, offering a rhythmic and responsive shift feel. Furthermore, the transaxle uses a built-in clutch to separate the engine and motor, allowing them to be used independently or together depending on driving conditions.
