FEATURES


  1. OUTLINE


    1. Hybrid System


      1. LEXUS Hybrid Drive optimally performs cooperative control of the 2AR-FXE engine, Motor Generator No. 1 (MG1) and Motor Generator No. 2 (MG2) in the P314 hybrid transaxle that provides excellent transmission performance for the front wheel drive system.

      2. On AWD models, the E-Four system optimally controls the Motor Generator Rear (MGR) through a Q211 rear drive unit that provides excellent traction performance for the rear wheel drive system.

      3. The hybrid system uses a high-output HV battery with a nominal voltage of DC 244.8 V, and a variable voltage system in which a boost converter increases the operating voltage of the system to a maximum voltage of DC 650 V.

    2. 2AR-FXE Engine


      1. This engine uses a high-expansion ratio Atkinson cycle, Variable Valve Timing-intelligent (VVT-i) system, Direct Ignition System (DIS), Electronic Throttle Control System-intelligent (ETCS-i) and Exhaust Gas Recirculation (EGR)*1system employing a highly efficient EGR cooler. Thus, improved engine performance, quietness, fuel economy, and cleaner emissions have been achieved.

    3. Transaxle


      1. The P314 hybrid transaxle is used for the front wheel drive system.

      2. On AWD models, the Q211 rear drive unit is used for the rear wheel drive system.

    4. Suspension


      1. A MacPherson strut type independent suspension is used for the front.

      2. A double-wishbone type independent suspension is used for the rear.

      3. An Adaptive Variable Suspension system (AVS) is provided in accordance with the specification.

    5. Brake


      1. A ventilated disc brake is provided for the front brake.

      2. A solid disc brake equipped with brake caliper-with-parking brake actuator is provided for the rear brake.

      3. An electronically controlled brake system is used to control the hydraulic pressure at the 4 wheels.

      4. The following brake control functions are provided: Anti-lock Brake System (ABS), Electronic Brake force Distribution (EBD), brake assist, Traction Control (TRC), Vehicle Stability Control (VSC), steering cooperative control, trailer sway control, hill-start assist control and brake hold.

      5. An electric parking brake system, which allows the parking brake to be locked and released using a switch, is provided.

    6. Steering


      1. A rack and pinion type steering gear assembly is used.

      2. An Electric Power Steering (EPS) system is used.

      3. A manual tilt and telescopic mechanism and a power tilt and power telescopic system are provided in accordance with the specification.

    7. Drive Mode Select


      1. The drive mode select is a function where control characteristics switches of the powertrain (hybrid control system), chassis [Adaptive Variable Suspension system (AVS)*, Electric Power Steering (EPS) system] and air conditioning (air conditioning system) are integrated. This function optimally controls each system according to the driving mode selected by the driver.
