Does anyone know if and when the RX is getting the 3.5 liter engine? Is anyone holding off buying the RX330 for the RX350 as the 3.5 is far superior in power and fuel economy.

 

The rumor is model year 2007.

 

That is correct!

 

Curious...... Does anyone know what the hp and mileage is for the 3.5L motor as compared to the 3.3L?

 

HP around 270 and in the April 2006 timeframe.

 

dammit should have waited... oh well... already ordered mine...

 

Does anyone have any real confirmation of there being a 350 in developement? I've seen rumors, but nothing even remotely official.

Thanks,

Also, anyone have any idea what pricing might be like?

 

Toyota has registered RX350 name in US market, so it will come. Question is when and how much more will it cost.

Will it have 270hp or 306hp (dual injection)?

 

Over here in Switzerland, the RX300 (we don't have the 330) is not being delivered anymore. It will be replaced by the RX350 in the beginning of 2006. Everybody who still has a RX300 on order will get a 350.

 

the rx350 will share the avalon 3.5 liter engine (270hp) because both cars are fwd. the 3.5 liter in the is350 is a different engine built for rwd cars.

 

Very intersting I did not know TM was still putting the old 1MZ -FE motor in the current RX. Any idea why they kept the 3.0 for european countries?

 

The 3.5L V6 used on the FWD and RWD Toyota/Lexus shared the same structure, displacement, borexstroke. The main difference is the higher output one benefits from direct injection.

The reason they keep the 3.0L engine in Europe and Asia (not even Japan has the 3.3L engine for the non-hybrid RX/Harrier. They do have a 2.4L though) is that their registration fee varies based on engine displacement, and usually brackets in every 500 c.c. The larger the displacement, the more you have to pay annually. The 3.0L will put you in the 2.501 to 3L bracket, while the 3.5L will put you in the next higher bracket. They should revise the policy as the old "larger displacement = lower gas mileage" concept is no longer necessarily true.

That's why we don't see too many American built car in those countries. And yes, the 1.3L twin-rotary RX7 and RX8 are taking the advantage of it, even they swallow gasoline like crazy.

 

according to the schedule. The GS450h in May. Should have the same motor as the Avalon which is 268 HP.

 

given the bump in power from 330 to 350, what will the Hybrid version be, RX450h?

In the above, they were talking about the next generation RAV4 coming out with a 3.5 L V6 with 269 hp.

My only question is why Lexus did not come out with the hp upgrades sooner.
