Walt,
Thank you for the reply. The information is very useful.
As one would expect, there's a huge hit in mileage on the highway between
55-70 and 80+. I live in the Berkeley hills (across the Bay from San
Francisco). Every trip I take starts and ends with a very long, steep
hill -- a cab driver once told me that our street is the steepest street in
the Bay Area, including all the San Francisco hills. Clearly, coming up
this hill once or more per day is taking its toll on my gas mileage. On the
other hand, compared to the car I replaced with the Highlander -- a 2000
Ford Explorer -- I am getting great mileage.
I was interested in your comment about the battery. I have not noticed the
battery bars ever going down more than two. Also, it seems that no matter
how gently I step on the "gas pedal," once the car reaches 15-20 MPH, the
engine starts. I'd never driven a hybrid before buying this car, but I was
under the impression that it used the electric motor more than mine seems
to. I will discuss all of this with the dealer when I take it for the first
service in 2,500 more miles.

We also have a 2997 Hylander Hybrid with 4WD-I. The cold weather
here in upstate NY is indeed hitting out mileage but for our
day-in-day-out driving with trips less than 15 miles we're showing
a consistent 23.0. On a 250 mile trip with a mix of interstate and
two lane highway (55 MPH limit) we showed 25.5 for the interstate
portion at about 73 MPH true, and 27.5 for the two lane portion
running about 58 true. This was largely level driving, following
the Mohawk River valley. Suburban driving, at 40-45 MPH, has
consistently shown 27-28 MPG. Our net consumption over the last
2000 or so miles has been 24.8 for all types of driving based upon
miles covered and fuel pumped, the most accurate of all.
Individual fill-ups has indicated that the car's computer is
just about right, as is the speedometer and odometer.
I'm impressed by this.
57 miles pulling a 1250# boat trailer generated 19.3 MPG at
73 MPH true. This was the average indicated by the car's computer.
Using the car's computer, I've found a few other data points.
At 59 MPH indicated, relatively level road, and with cruise control,
you can seriously discharge the traction battery in about 12 miles and
achieve, for that short distance, in excess of 33 MPG.
I live at the top of 1.25 miles of 9% grade, so I always start every
trip with at least 7 bars of traction battery. My short trips are
3-6 miles and seem to have little impact on battery charge. My longer
trips are usually initiated by the sequence in the previous paragraph.
I hope this answers some of your questions.

I recently bought a 2007 Highlander Hybrid Limited AWD-i. My gas mileage
isn't what I thought it would be. I didn't expect to get the numbers on
the window sticker, but I thought it might be close.
On a recent trip from San Francisco to Los Angeles and back, I got 22.0
MPG -- that's 750 miles round trip, all freeway driving, much at 80 MPH.
My city driving is about the same -- sometimes a little higher, sometimes
lower.
If anyone else has a Highlander Hybrid, I would sure appreciate hearing
about your gas mileage experience.
Thank you.
John
