I think if Toyota pairs it with a CVT transmission or the 8-speed Lexus tranny, that would be a good way to evolve...

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.

That makes NO sense.

Och

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.

pagemaster

What are you talking about?

The 2UZ was a huge volume engine, more so than the 1UZ or 3UZ, and perhaps combined. The 2UZ was likely close to 150k units worldwide

pagemaster

no worries, I don't want to turn this into a full blown analysis either. Just an FYI, the 1GR just recently received dual VVTi, but is staying a 1GR designation

flipside909

Agreed.

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.

pagemaster

I believe there is also a 5GR..

flipside909

That's correct. 2.5L V6 Non DI for the Chinese market.

03 ES

wrong.
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)

92 SC400

If the VQ can hang around this long, I don't see why the GR can't. It'll probably just evolve over time like the VQ has.

*Batman*

I think they should add turbos.

Opps my bad. Yes the accord uses the C27 engine. But still, the J-series was introduced in 1996 as an engine option for the 1997 Acura CL model

flipside909

Actually The RX450h uses the 2GR-FXE (3.5L V6) and the current Highlander Hybrid still uses the 3MZ-FE (3.3L V6).
