I am a Ford Escape 4WD Owner so I may have a bias.
I am impressed by the new Lexus Hybrid and if I were the King I would choose this car as my mobile throne, given its luxury. But, after my research, I have a few concerns about increases in estimated economy over the RX 330 and its use as a 4WD alternative. Lexus has not as yet given us a firm suggested MSRP price.
2005 Lexus RX 330
MSRP Price Range $35,775 - $37,175 (2WD - 4WD)
EPA Fuel Economy 2WD City 19 MPG
EPA Fuel Economy 2WD Highway 25 MPG
EPA Fuel Economy 4WD City 18 MPG
EPA Fuel Economy 4WD Highway 24 MPG
2006 Lexus RX 400h Hybrid
MSRP Estimated Price $44,000 - $54,000
EPA Fuel Economy AWD City 26 MPG
EPA Fuel Economy AWD Highway 30 MPG
As a Ford Escape Hybrid 4WD driver I have experienced a loss of power at high torque conditions (extreme 4WD) and now I read about the Lexus:
"Since the rear electric motor is air-cooled, there’s a concern for excessive heat build up, which would cause the system to shut down (to protect itself), temporarily leaving the RX 400h's passengers stranded. Not good when the tide is coming in." (From Edmunds)
You do the math from the RX 330 to the RX 400h. I am not yet sure the increase in MPG compared to the Estimated increase in cost and/or loss of 4WD power is worth it, even if you are the King.

One, if you are using the RX400h in extreme off-roading maneuvers enough to overheat the REAR eletric motor, you bought the wrong vehicle!
Two, the FWD would still work. The vehicle wouldn't be dead, just the rear aux motor.

When you consider cost, consider feature content. As is true of any Toyota/Lexus, adding features quickly adds to the cost. RX400h may be better equipped, and RX330 can easily exceed $40K mark with basic add ons. Besides that, the difference should also reflect in performance area. I have my suspicion. If Lexus were to put a powerful V8 under the hood that delivered similar performance to the hybrid, we wouldn’t be comparing costs.

My wife is trading in the original RX300 for the new RX400h this April. We are on the waiting list. I talked to a young and knowledgeable salesman at my dealer & he indicated to me that the gas mileage for the new hybrid would be more like 39 in the city & 29 on the highway. This 30 and 26 does not make much sense to me. I would think that the difference between the city & highway mileage would be considerably greater. Has anything actually been confirmed yet?

In my original post I got the posted information direct from the Lexus Website so I would guess your saleman is more of an expert. I am only saying that buyers should check out all sources since salespeople are often the last ones to really know what they are selling and receiving commissions for.

You are so right. I just talked to the salesman again this morning and he corrected himself. He said that a representative from the Dealer just got back from a briefing at Lexus headquarters & that the gas mileage is indeed 30 & 26. Lexus told them that the RX400h is a totally different concept than the Prius, etc. The RX400h is built more on performance. It is very powerful, smooth, & quiet. The gas savings is still much greater than any other SUV around, but is not what one would presume based on other lower end SUV cars to this point.

"Built for performance"?
Sounds like the Escape Hybrid.

I spoke to Lexus of Manhattan yesterday, and they said that they have not heard anything official about the customer tracking system, and that they only knew about it from the Lexus public announcements.
The salesman said he expects cars to arrive around April 15, in assorted colors, at which time they will invite all of their waiting list customers to come in and see the car. They will then go down the list offering first pick to the first on the list and so on. He said that they may not even know the available colors, let alone the colors they will get, before arrival.
This is the same way they will handle the new GS about to come out.

EPA estimates are usually conservative, to take into account real world factors. I have always gotten better mileage than the estimates, even for normal dirving, and especially on the highway.
The Prius EPA estimates on the other hand, were far too optimistic, with very few drivers able to achieve them at all. I think that probably relates to some aspects of the hybrid drivetrain that the test cycle unintentionally favors (high part load efficiency). It resulted in much furor, and even talk of a class action lawsuit.
It will be interesting to see how accurate the RX400h estimates are. I will begin testing as soon as I get it! I hope others will do the same.
