FEATURES


  1. OUTLINE


    1. LEXUS Hybrid Drive


      1. LEXUS Hybrid Drive optimally performs cooperative control of the 2AR-FXE engine, and Motor Generator No. 1 (MG1) and Motor Generator No. 2 (MG2) in the P314 hybrid vehicle transaxle assembly that provides excellent transmission performance. Furthermore, this 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 boosts the operating voltage of the system to a maximum voltage of DC 650 V.

        *: Maximum system output is engine output and MG2 output controlled by LEXUS Hybrid Drive. MG2 output depends on power supplied by the HV battery.

    2. 2AR-FXE Engine


      1. The 2AR-FXE engine is an in-line 4-cylinder, 2.5-liter, 16-valve DOHC engine.

      2. This engine uses a high-expansion ratio Atkinson cycle, Variable Valve Timing-intelligent (VVT-i) system and Electric Throttle Control System-intelligent (ETCS-i). In addition, use of an electric engine water pump assembly has eliminated the V-ribbed belt. Thus, improved engine performance, quietness, fuel economy, and cleaner emissions have been achieved.

    5. Steering


      1. The Electric Power Steering (EPS) system uses a power steering motor, a power steering torque sensor and a reduction mechanism that are built into the steering column assembly to generate assist torque, in order to assist the driver's steering effort.
