the GS450h hybrid was not built for fuel efficiency. it is more for performance, you get V8 power in a V6 package. so if you are judging the GS450h as an inefficient hybrid (ie: fuel efficiency), then you need to re-evaluate your judging criteria because fuel efficiency is not why people buy this car (i certainly didn't).

now my opinion... the lexus is a nice car and i loved the RX400h a lot lots of wood trim good leather, good looks... and then the 450h came. i was surprised at how much the interior degraded. it looks like my 2002 rx has more wood trim then the new 450h which is appaling. im a big touraeg TDI fan because its luxorious and has some off road capabiltes. The 450h doesn't have any off road you try taking it off road and one wrong move you'll break some important part. the new rx450h is for me
before we got your RX450h, we looked at a fully loaded RX400h. glad we got the RX450h because it is a better built and equipped car. interior for the RX450h looks great to me, and the available PSC, HUD, LED headlights, AFS, gen 6 navi, sideview camera, dynamic cruise control, most advanced lexus hybrid system to date, etc, etc all are heads and shoulders above the RX400h. so you lose some wood trim, no big deal. you need to look at the RX450h as an entire package, what it brings to the table, and it is superior to 1st and 2nd gen RX hands down.

That would be correct. The RX350 would be a poor off-roader as well.

The non-hybrid RX/Highlander/Sienna, Venza and the Matrix offer a viscous-coupling based AWD system which engages seamlessly without driver intervention. Audi and Volvo use such as system as well. Honda's Real-Time 4WD in the CR-V and Element and VTM-4 used in the Pilot/Ridgeline and the Acura RL/TL/SUVs are different beasts as is Subaru's AWD system. Real-Time 4WD doesn't use a viscous coupling, instead it uses a hydrostatic setup of 2 oil pumps in the rear diff, the system only engages the rear wheels when there's a marked difference in oil pressure between the 2 pumps. VTM-4 uses 2 electrohydraulic clutch packs in the rear diff which the system will activate in a low-traction situation. Subaru's system doesn't use a viscous coupling - it uses a unique transmission/transfer case arrangement that eliminates the viscous coupling and a conventional RWD setup for the rear wheels, along with some specific add-ons per Subaru's descriptions: http://www.drive.subaru.com/Win09/Wi...sWhatMakes.htm

So what? The LS600 uses a Torsen diff....so does the Lx570.

The new RX450h uses an a electric transfer case or something along those lines if I am correct. They have gotten rid of the mechanical centre diff I believe

I wonder what the exact same drivetrain would get in an IS body???

weight difference would be significant.

Probably some new tech. LExus has promised an IS hybrid next go round. Who knows maybe the next IS 250 gets the HS 250h powerplant.

IS is based off GS so maybe they share the hybrid tech

The IS Diesel in the UK gets close to 40mpg combined. A hybrid IS would get close to that or at least more.

The RXh and HiHy never had a direct mechanical link to the rear axle, a dedicated oil-cooled rear electric motor took care of that task. It was called MG3 or MGR. The 2 motors in the transaxle/inverter assembly were called MG1 and MG2.

it's no wonder you rarely see a GS450h. i believe annual production is around 5,000 globally. the GS450h is not a high volume production car and is a rare bird.

Yeah and that was in 2007, its probably less now. Only 2k for America in 2007. I've only seen one driving around in Atlanta all these years and I was shocked!

One of the reasons I love it.

I've seen very few GS hybrids, at the same time the GS just isn't a big seller. the GS450 will be more popular I believe once it recieves the updates that made the RX450 what it is. ...obviously not the 3.5L engine, since it already has that.

So I haven't been silent around here about how I think that a fast SUV is an oxymoron. IMO it's a waste of gas. Nevertheless, I do laud the quick RXh for its ability to hit 60 MPH in 6.2 seconds without depleting its gas tank. Anyway, I thought to myself, what is a luxury SUV that would compare to the RX450h in being quick and doing it in style? Heres what I came up with.

The Porsche Cayenne S, starting at $60,000. 0-60 in 6.4 seconds, so pretty close. 4.8L, V8. I believe the Cayenne is a bit bigger. It's fuel consumption is 13 MPG city, 19 Hwy. Not great, but there are definately worse. I bring up the Cayenne given that there is hybrid on the way. We shall see how it compares when it comes out.
