    still hoping for more posts advising:

    what the best mpg is that you can get?

    20 or so, if you are driving it hard?

    How do you do on a typical 70 mph highway commute?

    How is it in your typical driving? (i.e. normal around town, mixed with commute- your "normal" conditions)

    Just about done with my first tank of gas. Averaging 23.7mpg with an average speed of 25mph. Unfortunately I've only been commuting on roads with 40mph max so far and haven't had a chance to get out on the highway. I'm pleased with the economy, given the stop & go driving and many examples of stomping on the gas to show off the car's acceleration.

    We have the '06 RX400h -had for about a year now (paid full sticker, obviously) - mpg = high 20s average (30+ around town - with care!). Not impressed with your note about the mpg of the 450h around town - thought the hybrids did much better around town ? (vs. highway).
    Also - sure the rear-wheel drive is no bargain in the northeast, esp. with extra power of the el">link titleectric motor(s).

    I am getting better than EPA estimates on the highway 30-31. City driving realy depends on driving habits. If I am real careful, I can get 24 but otherwise it is 22-23. For comparison, my E500, with less power, was 15-16 in the city.

    We have a 400h too and it does a little better in the city but not as well on the highway.

    Any new reports on MPG?

    I'm curious how it does on an 75 mph commute

    as well as around town (seems like that is 21-24)

    and how is it on a 65 mph commute?

    "Not impressed with your note about the mpg of the 450h around town - thought the hybrids did much better around town ? (vs. highway)."

    The 450h was designed purely for performance purposes, not MPG. It is a 6 with the power of an 8 cylinder engine. It fits into the same category as the Hybrid Accord (except that the 450h is a luxury vehicle, where the Accord is a normal vehicle).

    The vehicle was not intended to get good gas mileage. Good MPG takes a 4 cylinder engine tuned for the Atkinson cycle, which does not support high performance such as Lexus requires.

    "Good MPG" is in the eye of the beholder

    I'd be thrilled with 22 mpg around town, if I could get 35 on the freeway at 75 or so

    especially at the luxury and driving level that the GS provides

    Can I get 40 mpg at 65?

    Can someone please provide thse numbers and burst my bubble so I can stop oining for a GSH?

    There was an article in the NY Times yesterday that's probably relevant to all of the readers of this board. "Greening Up With the Jones" -- login -- about being "light green", i.e. making positive choices about the environment and conservation while not sacrificing the finer things that money can buy. (if readers can't access the site, I can post the entire article).

    If you're about to drop $60k on a GS450h, you must care about both luxury & performance as well as the environment & energy conservation. If you only cared about the former, you'd be buying a 430, and the latter, you'd be in a Prius.
    I think the 450h is a terrific blend, and worth the extra several thousand for a great car that, if it catches on, may help move the industry in the direction of more innovative solutions like this one. Engineering should allow us to have our cake and eat it too.

    yes, this certainly fits my mind-set

    I have solar (electric) panels on my roof

    and a great hot tub

    ""Good MPG" is in the eye of the beholder "

    Yup, and the 450h will get better MPG than a similar class non-hybrid vehicle. But not in the same class as a Camry hybrid.

    The same thing happened with the Highlander Hybrid and RX400h; people read the title "hybrid" and expected Prius-like MPG. It doesn't happen that way.

    The GS 450h is an ideal blend. The only sacrifice one has to make is paying more money than would be the case for a car that was less gentle to the environment. If every luxury car on the road could get 20% better MPG and less emissions without sacrificing performance, the world would be a better place. :D
  • alp8alp8 Posts: 656
    any mileage updates? a poster in the Camry Hybrid forum noted that he gets 36 mpg at 80 mph. How close can the GSH get to that?
  • zeroohmzeroohm Posts: 7
    My commute is mostly highway with some stop and go at congestion points. Is there someone out there that has seen consistent highway mileage? I do wish the gas tank were bigger - I would like to be able to go 600 miles between fill-ups. Looks like I will be lucky to hit 475 in this car.

    28-31 mpg regularly on a 150-500 mile trips at 70+ mph including hills up to 2350 ft above sea level; 25-27 mpg in shorter in city driving. For first 3000+ miles driven, 80% highway, 20% city, avg mpg 28.2 and still rising! Last three tankfuls have averaged >29 mpg, including mix of aggressive highway and city driving. Lowest mileage during short 1-2 mile trips when electric battery is lower on charge and gas engine kicking in earlier than usual, but then still 20-22 mpg. For some reason driving in heavy rain with much water on road leads to lower mpg (25 mpg).
  • eli73eli73 Posts: 4
    Obtained 35 mpg going 65 mph for a 50-100 mile section of the Pennsylvania Turnpike on a holiday weekend when troopers were swarming. Very hard to maintain that discipline in this car, however!
  • I just got my GS 450h. It was used and had 2000 miles on it. If there was supposed to be a really thick owner's manual, then I don't have it. All I have are "Quick Guides". I can't find out how to reset the Tank Average in the display screen after putting in a full tank of gas. I thought that opening the fuel door would reset it, but it didn't. Is there something you have to do to reset it?
  • ideleidele Posts: 200
    The on screen average (this is the navigation screen; don't know if navigation is absent that it's present) is long term. It resets when you use reset button on screen. There is on dashboard (you have to get it by scrolling) a tank average which resets upon fillup automatically. Also on dashboard you can scroll to get graphic display of instantaneous mpg instead.
  • Thank you for that. I'll look for the instant mileage on the dash display. I believe my tank average is not working with the gas cap opening and closing. Did you get a thick owner's manual?
  • flidflid Posts: 11
    Yes, there is a standard set of owners manuals that are in a Lexus cover/binder that fits in the upper left area of the glove box. This is in addition to the "Quick Guides".

    How did you end up with used one with 2,000 miles? Dissatisfied customer? I just got mine (have only just over 100 miles) and couldn't imagine giving it up...
  • ideleidele Posts: 200
    The average mpg on the car (never reset) now stands at 27.9 after 2800 miles. It is slowly improving as the car breaks-in. The tank average mpg (a different readout which automatically resets upon fillup) stays above 28mpg which meams the total average mpg will move to 28mpg in a little while. The GS450h is such an excellent performer that the fuel efficiency is a very nice bonus.
