Looks like I found my answer.

The Toyota/Lexus 3.5 is part of the GR family of engines which is based off the 4.0 GR engine used in 4runner, GX and other Toyota trucks.

The 2010 LS will have a 3.5, Making 310hp.

Not yet confirmed.

And it may only be available in Asia and Europe, not the U.S. market.

But honestly, if the IS350 (3400 lbs) and the GS350 (3600 lbs) can ride well with it, I think the LS350 (4000 lbs) can, albeit not sportily. But then again, who rides the LS sportily?

Is it our engine? How come they get 4 more HP.

Different exhaust system maybe???

I think that's a good idea, especially for the Asian and European markets.

In my latest trip to Taiwan all the S-class and 7-series I saw over there are the S350 and 735i. Unless I wasn't paying attention, during my 2-week stay I didn't spot a single 8-banger S/7. The LS is already selling well despite has only one engine choice (not counting the halo LS600hL) so with the 2GR-FSE joining the lineup I can see it become a huge success.

4.6, 5.0, 5.7 v8 = ur

2.5, 3.0, 3.5, 4.0 v6 = gr

I think one question we should ask is could Toyota, the ES, IS, HS, as well as a bunch of hybrids benefit from a current 2.8 to 3.0L engine? Toyota has a bunch of 3.0L engines, but they are dated. GM has a new DI 3.0L and Ford is offering the Fusion with a choice of two V6's. Why not Toyota?

Lexus doesn't have any 2.8L engine.

Both the 4GR-FSE (2.5L V6) on the IS250 and 3GR-FSE (3.0L V6) on IS300 (Middle East and China) and GS300 have DI.

I don't think Toyota/Lexus is using the 3.3L V6 anymore, it was replaced by the 2GR (non-DI for Toyota/ES/RX and DI for GS/IS).

Camry doesn't need two V6s in order to sell, more engine choices = higher cost.

So with all due respect, what's your question exactly?

pagemaster

Toyota still uses the 3.3 v6 in the USA spec 2009 Toyota Highlander Hybrid.

There are some overseas markets that actually still use the 3.0, 3.3 and 4.3 is some Lexus cars. The GS is still a GS300 in some markets. There also GS430 is some markets as well. Not all are 4.6.

He probably wondering if there's a market for a vehicle somewhere in between the large 2.5 litre 4 cylinder model and the 3.5 litre V6.

It may work in Asia where cars are taxed on engine size but frankly in the Camry, the hybrid takes care of that void (189hp is in between the two and 0-60 time is in between the two).

ES? maybe. IS? Nah. It already has 2 V6 options. It doesn't need to be a 3 Series with three 3.0 litre options with various tuning.

HS? Nah. It only needs one engine option and was hoping it'd be the new 2.5 litre but I guess Toyota wants to recoup some more cost from (or rather maximise the use of) the 2.4 litre it put in the TCH.

Here is more info on GR engines, without having to make silly guesses:
http://en.wikipedia.org/wiki/Toyota_GR_engine

Its modern as it goes, and 2GR-FSE has been on Ward's top ten list for 2006, 2007, 2008 and 2009. I dont think R series will go anywhere for a long time, no better engines exist right now.

It goes like crazy in my GS350 AWD, which weights similar to LS so I dont see why would it be the problem.

pagemaster

Here is some correct info on weight so you don't need to make silly assumptionshttp://www.lexus.com/models/GS/detai...fications.html
The LS460 weights 300lb more than GS350AWD

Yes that was my point.
Wrong. Not meeting CAFE standards = higher cost.

Yes, Toyota doesn't have a 2.8 V6 but they do have a 2.7 I4 which serves the purpose just as well if not better if the focus is on fuel economy and CAFE standards.

Toyota also has the new 2.5 to replace the old 2.4 with higher power output and better FE.

Camry currently has 3 engine configurations and if I am not mistaken, the hybrid and 4-banger models made up about more than 3/4 of the total Camry sold. So IMHO, CAFE standards really is not a problem for Toyota, at least not for the Camry.

Let's also not forget that Toyota/Lexus has the 4GR-FSE (2.5L DI V6) and 3GR-FSE (3.0L DI V6) so to develop a 2.8L IMO would be resource wasting and totally irrelevant.
