OUTLINE
The 1GR-FE engine is a V-type, 6-cylinder, 4.0-liter, 24-valve DOHC engine.
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.
*: Models for compliant with EURO 5 and EURO 6 emission regulations
