Lexus GS 450h: MPG-Real World Numbers by pf_flyer HOST

With the price of gas being what it is, your real world mileage is becoming more important than the estimates on the sticker. This is the place to talk about your real world on the road results!

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.

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.

"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" -- http://www.nytimes.com/2006/05/14/fashion/sundaystyles/14_GREEN.html?_r=1&oref=s- 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 nytimes.com 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.
