ENGINE UNIT


  1. OUTLINE


    1. The 2GR-FKS engine is a V-type, 6-cylinder, 3.5-liter, 24-valve DOHC engine. This engine is a Direct injection 4-stroke gasoline engine Superior version (D-4S) which uses both direct injection and port injection systems. In addition, this engine uses the Variable Valve Timing-intelligent Wide (VVT-iW) control, Variable Valve Timing-intelligent (VVT-i) control, Direct Ignition System (DIS), Electronic Throttle Control System-intelligent (ETCS-i). It has been developed to achieve high performance, quietness, fuel economy and clean emissions.
