The 3.5 V6 started out with a 5 speed transmission in the Toyota Avalon. It then eventually gained an extra gear over the years with the 6 speed.
The 4.0 V6 started out with a 4 speed in the Toyota 4runner which then went to a 5 speed.
The 5 speed transmission used in the LC, Tundra, and 4runner has now added another gear is going now be labeled a 6 speed with the new 4.6

So don't go assuming things you have no idea of.

I am not "assuming" anything, and again, that's why I use the word "probably".
I am not an expert in engines and transmissions and I'll be the first one to admit that but I do remember reading from somewhere before that mating a transmission to an engine isn't as easy as plug-and-play.
Even though if the 8-speed can be mated with the 2GR-FSE that probably won't happen without some tweaking and modification so if the 6-speed serves the purpose why waste resource?
Oh by the way, if you have some FACTS to prove my assumptions wrong then by all means share with us. This is a discussion forum so until something has been proven I can assume whatever I want as long as I stay reasonable.

I disagree. Well sort of. Note that I said a range from 2.8 to 3.0Ls. So yes, Toyota has several dated 3.0Ls. However, they have an existing 2.5L (that puts down more power than the 2.7L I4) and it's great engine, but the IS 250 is pretty slow. I'm not overly familiar with the setup of this V6, but automakers bore out engines all the time rather than designing one from scratch. And with smaller turbocharged engines on the rise, a 2.8L turbo would not be an irrational choice for a vehicle like the GS, Rav4, etc.

Huh?
You do know that the 3GR-FSE (3.0L DI V6) is brand new and has nothing to do with the previous 3.0L I6 found in the 1st gen IS300, 2nd gen GS300 and Supra right?
I do agree with you that the IS250 is slow and if it's up to me I'll replace it with the Middle East/China IS300. However, the IS sales are somewhat consistent and most of the people who bought the IS250 really don't give a crap about performance. For those who want performance the IS350 is just several grands away with 100+ more hp.
I really failed to understand why you are so hung up on the 2.8L. If Toyota/Lexus want to go FI they can put a turbo or supercharger on either one of their 2.7L I4, 2.5L V6 and 3.0L V6. Any of those combinations will make a kick *** engine with decent if not great FE. By the way, TRD already has a supercharger for the 3.5L V6 (non-DI version) and it was on the now-discontinued Australian Aurion.

So let me break this down for you so that you can understand.
The 4GR-FSE is an efficient engine, but with only 205 HP it can't propel the IS in any direction very quickly. Boreing this engine out to a larger displacement would be ideal for a base IS model that is embarresingly slow in today's market. Sure you could turbo the 2.5L. I won't disagree with you there. But, I honestly don't see Lexus using a turbo I4 in a GS, IS, ES sedan.
Companies like Audi had great sales success with smaller displacement V6 turbos. BMW is enjoying that now with their 3.0L.

And Toyota doesn't use it anymore. Not in the GS, IS, or Aurion.

The 3GR-FSE is in the IS300 in Middle East and China and I think some JDM Toyota models use it too although I am not 100% about it. By the way, does anymore know if Lexus is still selling the 3GS with the 3GR-FSE (GS300) in some markets outside the US?
Again you are hung up on the IS250 not being fast. Like I said in the previous post I agree with you and I think the Middle East/China IS300 should replace it here in the US. However, from Lexus' point of view since the IS250 is selling well enough and the owners aren't complaining then why change the formula?
As for Lexus going turbo, I don't see that happening anytime soon. I've said it more than once here, honestly I think hybrid is Toyota/Lexus' answer to FI engines. the hybrid version of the 2GR-FSE in the GS450h serves the same purpose as the turbo-/super-charged engines while achieving better FE.

Mmm, Lexus should get on this. Doesn't seem like it will be here for 2010. I think if they are going to install the 3.5L unit, an LS450h (RXh setup) would be a fine idea to compete with the S400 hybrid. The price would certainly be more reasonable than the 600hL and could really spice up the luxury hybrid market.
