ENGINE UNIT GENERAL

  1. OUTLINE

    1. The 1GR-FE engine is a V-type, 6-cylinder, 4.0-liter, 24-valve DOHC engine.

    2. On this engine, the Dual Variable Valve Timing-intelligent (Dual VVT-i) system, Electronic Throttle Control System-intelligent (ETCS-i), and air injection system* are used. These control functions have been optimized to further improve engine performance and fuel economy, and to reduce exhaust emissions.

    Tech Tips

    *1: Weight shows the figure with oil and coolant fully filled.

    *2: Except models for Europe

    *3: Models for Europe

    *4: Premium unleaded gasoline with a research octane number 95 or higher required for optimum engine performance. If 95 octane cannot be obtained, you may use unleaded gasoline with a research octane number as low as 91. Use of unleaded fuel with a research octane number lower than 95 may result in engine knocking and significantly reduced performance. Persistent knocking can lead to engine damage and should be corrected by refueling with higher octane unleaded gasoline.

    *5: Models for Europe, Hong Kong and Turkey

    *6: Models for Australia, Argentina, Russia and Taiwan

    *7: Models for G.C.C. countries, general countries, South Africa, Pakistan and South America

    *8: Models with air injection system

    *9: Models without air injection system
