2019 6th Gen 4runner

[JLTD]

....

TLDR version: I predict a 3.5L with e-torque assist to fill in the torque gaps. So like 300 hp, and 300 torque with a smallish li-ion battery under the passenger side and 23/24 city/highway mpg, with a 4200 lb curb weight with 4wd.

All that complexity for the same mpg...granted mine is stock, but I can easily get 23 on a long trip if I take it easy. I think Toyota might prefer the reliability angle for the T4R, going with proven NA engines rather than new tech

FWIW - the 4.0L 1GR block from 2010+ is not shared with the pre 2010 1GR block. So the castings are all new around 2009. The only shared parts I can find between the two are the crank shaft bearings. There may be a few more, but nearly every part is different. Reaching the 8th year of production is still a fairly long time though.

The 3.5 with proper gearing would do okay. Sometime test drive an RX350. It may change your mind about the 3.5. I also have an RX350. So I drive them back to back quite often. It's remarkable how much better the RX350 feels vs the 4Runner with very similar numbers on paper. The key is the gearing being much lower and the transmission shift logic being a bit more focused on performance than mpg. I also think the 4.0 could continue on happily with better balancing, D4S, and an 8 speed transmission. I'd buy one.

The Atkinson Cycle is what kills the 3.5 Taco. Without it it’s a good engine.
