And it could easily be fitted along with an 8 speed auto in the 4Runner for very little manufacturing cost difference. And would likely get significantly better mpg.
The 1GR is a fine engine. It was top of class when it was introduced in 2002. In 2020 - it's not so competitive anymore. The 3rd gen 4Runner was still on sale and came with a cassette tape deck when the 1GR first started selling in Toyota models. It's a very reliable engine. But it's past time for an update to something with a much wider range of efficient power output.

The 1GR that came out in 2002 for use in the 2003 4th gen 4Runner, has little in common with the 1GR in the 5th gen 4Runner.
Sure it's a still a 4 liter V6, but almost every part of the engine has been improved. The block, the crank, the cylinder heads, the intake, etc.
