In 2006, the 4.6-liter Toyota 1UR-FE engine was released as a powertrain for SUVs, full-size pickups, and executive models intended for emerging markets. The power system is where it differs most from 1UR-FSE: distributed injection rather than direct.
The engines in the UR family are 1URFE, 1URFSE, 2URGSE, 2URFSE, and 3URFE.
The engine was mounted 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;
- Lexus GX 460 J150 since 2009;
- Lexus LS 460 XF40 in 2006 – 2017.

Disadvantages of the 1UR-FE engine
Oil consumption is moderate for some owners;
The timing chain may abruptly loosen as a result of a hydraulic tensioner failure; the water pump begins to leak on runs up to 100,000 kilometers;
The ETCS-i electronic throttle system occasionally malfunctions; piston rings are a result of urban operation; there was an official recall in 2010 to replace the valve springs;
This powertrain’s overall dependability is significantly higher than average.
