The Toyota TR engine is a family of DOHC 16-valve petrol engines produced by Toyota, started in July 2003. These engines are primarily used in medium-sized passenger and commercial vehicles with body-on-frame platforms. They are designed for longitudinal mounting in both rear-wheel drive and four-wheel drive applications. Every engine in the TR series is a square engine, meaning the bore diameter and stroke length are equal.
In January 2015, the TR engines were updated with Dual VVT-i technology, identifiable by the additional VVT-i solenoid on the top of the cylinder head cover. However, the original single VVT-i configuration remains in production for specific vehicle models.
