In brief, Xterras in the U.S. market were powered by two gasoline V6 engines across their production run: a 3.3-liter V6 in the early models and a 4.0-liter V6 in later ones. The Xterra was produced from 2000 until 2015, with the engine lineup evolving between generations.
Engine options by generation
First generation (2000–2004): 3.3-liter V6
The original Xterra relied on Nissan's 3.3-liter V6 engine, designated VG33DE. It provided a solid balance of everyday usability and off-road capability for the early model years, with transmission choices that varied by trim configuration.
Key details about this engine option:
- Engine: 3.3 L V6 (VG33DE) gasoline
- Years: 2000–2004 in U.S. Xterra models
- Configuration: DOHC, 24 valves; paired with available manual or automatic transmissions
These early Xterras defined the model’s initial, more economical power profile before Nissan updated the lineup in 2005.
Second generation (2005–2015): 4.0-liter V6
Beginning in 2005, Nissan swapped in a larger displacement 4.0-liter V6, the VQ40DE. This upgrade offered stronger performance, improved towing capacity, and better on- and off-road ability, and it was used across most trims during the remainder of the Xterra’s production run.
Key details about this engine option:
- Engine: 4.0 L V6 (VQ40DE) gasoline
- Years: 2005–2015 in U.S.-market Xterras
- Configuration: DOHC, 24 valves; shared lineage with other Nissan trucks/SUVs such as the Frontier and Pathfinder
Today, Nissan has not released a direct successor to the Xterra, and the two-engine lineage remains the defining powertrain history of the model.
Summary
In brief, the Nissan Xterra’s engine history centers on two gas-powered V6s: a 3.3-liter VG33DE in the 2000–2004 models and a 4.0-liter V6 (VQ40DE) in the 2005–2015 models. The 4.0L option brought greater power and capability, reflecting how the Xterra evolved during its production run, which ended in 2015. No direct Xterra replacement has been launched by Nissan since then.
