ENGINE UNIT


  1. OUTLINE


    1. The 2GR-FE engine is a 3.5 liter, 24 valve DOHC V6 engine. This engine uses a Dual Variable Valve Timing-intelligent (VVT-i) system, Direct Ignition System (DIS), Acoustic Control Induction System (ACIS) and Electronic Throttle Control System-intelligent (ETCS-i). These control functions achieve improved engine performance, fuel economy, and clean emissions.
