LS600hL Hypocrisy?

Pole Position
The 600's transmission is a theoretical CVT. It is still an eight speed geared unit. However, it is computer assisted to provide a CVT-like smooth response. Lexus chose to categorize it that way as it is unique in its performance and is more akin to CVT characteristics. You can expect this approach to become more popular than the pure CVT in the future due to its inherent durability.

Thats weird...it's either a 8 or a CVT. LS trannies are super smooth as they are. I can barely feel mine and it's an 02. Nevertheless, it's no CVT. I'd love to see the diagram for this "theoretical CVT".

Nauticalx, You are correct, it is purely politically correct and good corp image to make the largest flag ship car with the largest engine a partial hybrid. It keeps the tree huggers at bay.
You are smart enough to actually figure out how the car works. Whats funny is Lex had to pump up the liters and the HP just to keep the car as fast as the 460. Pushing an AWD trans and the weight of an electric motor the 600 may be not as fast as the 460swb, we will see, but it is PC when you show up at parties

The problem with this all is the dichotomy of producing what people need (perhaps) vs. what they want.
Hybrids as they are presently produced have very little to do with increased fuel economy. Most of them have to do with producing cars with increased power than their normal counterparts.
Why don't all the car makers produce hybrids with 1.4L engines instead of 3.3L engines? Because people don't want them. They are producing what people want to buy. Of course, they are shrewd enough to hide them under the "green" politically correct credentials of being a hybrid, but in reality they are just making faster cars that people want to buy.
Did the NY Times reporter just wake up and realize this???
They don't bother with the hybrid "nonsense" in Europe. They just buy diesels.

I wonder what kind of fuel economy (highway) numbers they would have gotten increased simply by adding a variable displacement cylinder deactivation feature on the 4.6 or even the 5.0 without adding the hybrid motor.

Not sure. GS 450h is advertised as 25 city/28 highway with a detuned 3.5 V-6. The car weighs 4100lbs.

Sorry Mike, not trying to argue, but according to Lexus' web site they will use the revised figures for 2008 model year and the current GS450 listed is still the 2007 model.
From lexus.com when clicking on 'mpg':
And from the FAQ:
Don't know if this link will work but here goes:

From lexus.com when clicking on 'mpg':
Beginning with the 2008 model year, the Environmental Protection Agency (EPA) has implemented a new method of calculating fuel economy estimates to try to more realistically reflect actual day-to-day driving. The new fuel economy estimates use existing test data and apply a different method of calculation to determine 2008 model year values. To learn more about the new mpg estimates, please visit our FAQ page.
Have all of the current Lexus models' mpg numbers been revised to reflect the new standards?
No. The revised method of fuel economy calculation is being applied to all vehicles beginning with the 2008 model year.

Finally, according to Edmunds...
http://www.edmunds.com/advice/fuelec...2/article.html
Hybrids take the biggest hit
Taken together, the higher speeds, use of air-conditioning, hot and cold temperatures and more aggressive acceleration and braking will bring 2008 ratings down. According to the EPA, city ratings will drop about 12 percent, with some losing as much as 30 percent. Highway ratings should fall an average of 8 percent, but could drop by up to 25 percent.
