All 2UZ-FE engines produced after 2007 are equipped with Variable Valve Timing, commonly known as VVTi. This intelligent system manages nearly all vital engine parameters: throttle position, coolant temperature, air volume, and more. Utilizing this data, it adjusts the intake camshaft timing to enhance engine performance and efficiency across low, mid, and high rpm ranges. Another notable feature is the plastic intake manifold with an adjustable intake port length, regulated by Toyota's Acoustic Control Induction System (ACIS). This system operates with two intake port lengths: a longer one for low engine speeds and a shorter one for higher speeds.

Within the 2UZ-FE VVTi engine, newly designed lightweight pistons and oil jets are installed in the cylinder block for cooling. The compression ratio has been increased to 10.0:1 to optimize fuel combustion. By 2010, the 2UZ-FE VVTi had fully replaced the previous engine model. However, starting in 2008, the 4.7-liter engine began a gradual phase-out, being superseded by the newer 5.7-liter 3UR-FE and 4.6-liter 1UR-FE engines.
