It was a personal poke at other posters, no matter how you cut it. But I gather from your follow-up that your intentions were more honorable than the net result? Given so, all is forgiven and I apologize for calling you on it.

Considering all the magazine reviews got 19~20mpg during their short tests, 23-25mpg for ordinary owners would be more reasonable.

I question that, only because I pay more attention to the EPA ratings, and adjust from there. Granted the '08 system might be closer to reality, but the '07 system usually caused folks to adjust downward slightly. Assuming the '08 is more typical, then it makes sense that the average person who owns this kind of car will put their foot into it once in a while to squeeze some performance out of it, and also will achieve around the rated EPA, which is 20/22, for an average of 21.
 
But, of course, we'll know more after owners start reporting.

   They have the 2007-2008 comparisons, and owner surveys.
 
   I notice the Camry Hybrid, for example, went down from a 39 MPG cobimed to 34, but the owners averaged 36-37MPG.
 
   One thing about Hybrids. They are kind of like a video game, as some drivers will adjust and try to drive up their economy, and figure out where the car is most efficient, and take advantage of those situations.

Yes, Doc... I think that is very true for some!! And I must admit that I HATE getting stuck behind those particular penny-pinching, fuel-economy-challenged, slow-pokes on the road.
 
My experience so far has been that most hybrid drivers are pretty cool and they just go for it, but then there are those... "OTHERS".

I haven't run into ANY hybrid drivers clogging up traffic. I have seen them blitzing the left lane, flying so fast, I can't keep up!
 
   The "Slow-pokes" are ALWAYS Corolla drivers.

Well, Doc, here in California, there are a lot of Prius and Civic hybrids... we could very possibly be the "greenie" capitol, not sure. But when I say there are a lot of them, man, I mean a LOT of them.
 
There isn't a day goes by that there isn't one of those Prius vehicles going to slow. But, you are right about many of the others... they go flying by! So the problem isn't the car... it's that video-game hybrid driver you were talking about, challenged to squeeze every nickel out of his tank of gas, and trying to see how far he can go between fillups... it's a new "sport" of some sort, isn't it?
 
To be fair. there are plenty of other cars that do the same things, and the ones that jam up traffic should be removed. One self-centered individual can ruin a drive for many other folks.
 
Now, with all that V-12 power the LS600hL is supposed to have, I'm expecting them to be flying by, but you and I both know that the same kind of video game hybrid driver could be at the wheel, and God-forbid, enter into the "sport" of squeezing 23+ mpg out of that thing instead of the rated 20/22.
 
Fortunately, there will be very few of them, so the impact will be minimal... and as I understand one of our posters... there should be a chauffeur in the driver's seat anyway!

It is true that you have to learn how to drive a hybrid and having a kW meter instead of a tachmeter is of enormous help since one horsepower is a constant multiple of kW (1 hp = 1.34 kW). The penalty of accelerating up grades is substantial. That's true of all cars but it's right in front ofyou in the Lexus hybrids. I had an RX400h for 11 months before trading to the GS450h last year. The RX400h was better at stop and go mileage but distinctly inferior at speeds above 60, so my lifetime average is better with the GS450h.In fact I now choose a longer route to and from my home to utilize the interstate. I live in a moderate climate. There is a temperature sensitivity with hybrids. My tank average (average mileage reset automatically upon filling the tank) runs around 26.7mpg during cold weather. It's running at 29.1mpg tank average right now. I like my car cool so during the summer with the air conditioning going full blast I'll probably get down to 28.1mpg tank average.
The LS600h will have a better battery pack. Toyota has its own chip plant (the only one among the major manufacturers) and I expect the absolutely vital electronic control system to be expertly adapted to the LX600h.
In brief that's the background for my mpg estimate for my driving a LS600h. Insofar as car magazine articles, I don't trust most automotive journalists. Journalists are generally chosen for their ability to write; think of all those catchy phrases. Moreover their stories are usually centered about a single theme. In the case of hybrids, fuel efficiency seems to be the one usually chosen. Well one can take any car and drive it in such a way as to worsen any set fuel efficiency figure. It makes a better headline to do so.

28-29MPG is impressive for a 330+HP car, that is as fast as the LS600h!
 
   This also shows that the EPA numbers may be pessimistic when it comes to Hybrids, because the Hybrid "tells" the owner how to improve economy. This is a huge factor, adjusting driver habits.

Not the case. If you go to the EPA website, and use the Prius as an example, you will see that the '07 rating sytem provided a 55 average MPG rating. The '08 will reduce that number to a 46 mpg average. That's only a reduction of 17%, far less than the 30% that I had been reading about in some of the articles, which is good news for the hybrids.
 
To give you the correct answer, though, it seems that the reported real-life average mpg for Prius owners themselves is 45.1. That's VERY close to the '08 new rating, which is very interesting.
 
So, it seems that the EPA numbers were not pessimistic with the '07 rating system, and are not pessimistic as we move towards the '08 rating system... it was the other way around. The EPA was overly optimistic and favorable.
 
Now, that AVERAGE of 45.1 consists of a few wreckless drivers that only got 34, and a few that squeezed out 61. Those drivers demonstrate the potentials at both ends of the spectrum. The average is what matters mosts, and it is essentially gives the '08 ratings increased credibility.
 
The RX400h is another example. It had an '07 rating of 29 average mpg. The'08 rating takes it down to 26... only an 11% drop. The average in real life is 24.2. Once again pretty close to the '08 estimate, which is still a little optimistc, not pessimistic.
