The 4.6-liter Toyota 1UR-FE engine was introduced in 2006 as a powertrain for SUVs and full-size pickups, as well as executive models for emerging markets. Its main difference from 1UR-FSE is in the power system: distributed injection instead of direct.
The UR family includes engines: 1UR‑FE, 1UR‑FSE, 2UR‑GSE, 2UR‑FSE, 3UR‑FE.
The engine was installed on:
- Toyota Land Cruiser J200 since 2012;
- Toyota Sequoia XK60 in 2010 – 2012;
- Toyota Tundra XK50 since 2010;
- Lexus GS 460 S190 in 2007 – 2011;
