Some of the engine noise you hear, at least on the Tacoma, is artificial. I don’t know about the Land Cruiser or 4Runner. That said, it isn’t a lot better with augmentation disabled.
You can always just crank up the music and ignore it.
It has everything to do with it. You are complaining about pricing of the new 4Runner. Yet you can’t provide something that is competitive and way lower priced?
My 2024 Tacoma Off-road Premium non hybrid gets 18 mpg as the tank average in the city. That’s 1 mpg better than my 2024 4Runner Off-road Premium. Both are stock.
I would not assume you are going to get much better.
