Life after the Toyota 3.5 engine?
#17
My prediction is that five years from now we will see change. GM is already moving to a smaller V6. Audi has done the same and added superchargers where neccessary. Presumably cars will be getting lighter in the future. Add technology like direct injection and your Camry, ES, etc. will not need an engine as big as the 3.5L. Furthermore, Toyota needs an engine to pair with its hybrids. The 3.5L in the RXh does a fine job, but a Highlander hybrid for example would sell better with a less powerful, more efficient setup IMO.

What I mean was that the 1UZ and 2UZ started off with basically similar designs, no vvt, 4 speeds and eventually changed. While the 1UZ was upgraded and upgraded and eventually became the 3UZ...the 2UZ on the other had was upgraded once (similar to what the 1UZ got at first) and then that was it, it never got a new designation like upgrade like the 3UZ.

I just used these as an example to predict where Toyota is gonna go with the GR engine - they are gonna fine tune and perfect it over the coming years. I'll leave it at that.

Well, whatever, the 2UZ was a rather low volume engine. Lets not drag this into full blown analysis of 1/2/3UZ. I just used these as an example to predict where Toyota is gonna go with the GR engine - they are gonna fine tune and perfect it over the coming years. I'll leave it at that.
GR series is a pretty versatile engine family. 4 versions: 1GR - 4.0L, 2GR - 3.5L, 3GR - 3.0L and 4GR - 2.5L.
Now if they would quit using the 4GR in the IS250 and upgrade it to a 3GR-FSE...now we're talking.

the 96 accord used a C series 2.7L V6, which was used in the 88-90 legend...it resurfaced in the 96 accord V6...
the J series debuted in the 98 accord V6 and later in the 99 3.2 TL.
on the note of the GR engines, i dont think theyre going anywhere anytime soon...its a pretty advanced engine, and its very versitile since it has a very broad range of applications across the toyota/lexus line...im sure we will see tweaked versions of it and maybe larger displacement versions, but itll be with us for a while longer.
you gotta remember toyota uses the same engines for a good long time (the previous V6 MZ engine lasted from 94-07 and its still in the highlander and RX hybrids)
