Agreed ! Can't imagine putting those hideous hov stickers on any Lexus.

 

I wouldn't mind the sticker if it meant I could use the carpool lanes

 

Averaging approx 24mpg on the 450h so far. Like someone already said, it can't even come close to my prius 48-53mpg.

 

that seems about right... Also, what is the speed difference between the two?

 

The 07 S550 was tested at 5.3 seconds 0-60. That is a tenth of a second slower than the GS450H based on published statistics. The two vehicles should have rougly identical acceleration to 60 mph.

 

My wife and I took the 450H on a 300 mile cross state trip this weekend, and with the cruise set at 70 and the AC running full blast, mileage clocked in at 31.5mpg. I manually calculated the milage to double check the trip computer, and it was spot on. The EPA highway rating is 28mpg, so I'm quite pleased.

As for city mileage, I only averaged 21 over the first 400 miles of suburban driving, which is well below the EPA estimate of 24. I was getting 20mpg in the GS 300 driving the same routes, so this is disappointing.

 

Cool, definitely sounds more oriented for performance rather than fuel efficiency.

 

I've been as high as 25.2mpg, but typically around 22mpg.

Note: less than 500 miles on the car, and on my 2nd tank of gas.

 

yeah, you are getting 20% better mpg, while being 2 secs faster 0-60 and it is very dissapointing... lol.

 

I didn't get 20% better; I got just about the same.

GS 300 = 20 city / 30 hwy
GS 450H = 21 city / 31 hwy

The part that's dissapointing is the city mileage. Driving the 450H the same way as I was drivng the 300 - not faster, not slower, not more agressively - then I assumed the hybrid would get better mileage than the 300 in city driving. My daily driving is fairly conservative under conditions with frequent stops and speed limits in the 30-50 zone. This should be where the hybrid technology pays off, but so far I haven't seen that.

I know mileage varies greatly from driver to driver, and this is why I compared the 450 to the 300. The fact that the 450H can do 0-60 2 sec quicker is a real plus, but I think if you put that extra potential into frequent use, you're going to get milage well below what I've seen so far. I'll put the car in sports mode on the next fillup and push a little harder to test my theory.

 

I'm sure the GS350 won't be more than a few mpg less.

 

MPG update. Glad to report that my mileage has gotten better. My relatively short commute averages 24.8-25.1 mpg now, long freeway trips average 28-29mpg.

 

I get 28mpg on average.
My worst when I purchased it was about 22, and my best has been 34mpg.
But I regularrly ge 28 mpg and that 1/2 city and 1/2 highway, at speeds about 85-95 highway.

 

I bought my GS450h in mid January of this year, and was initially getting about 22mpg on my regular commute (which is about 15 miles long, with about 9 of it being a semi-congested highway). But then spring and summer came, and my mpg increased dramatically to over 25 mpg.

On the highway, having cruise control set for 69 mph, I get about 31-32 mpg, depending on whether there are any hills or not.

 

ya, but it's still a Prius. There are so many great reasons that I hope the GS never comes close to the Prius.
