2006 HH AWD base by peralta

Now 23k on the odo. 33 miles to work 95% highway.
Average 28-30 mpg per tank.
Some of my short local drives can be as high as 50 mpg.
I tried many techniques. Cruise control at 57 mph gives good mpg but slow travel overall. Or I drive like a roller coaster, accelerate on the downhill and let it slow down on its own at the incline. I get the same mpg but the second technique is faster and more fun. Most of the time, I combine them, using cruise control on downhill once the speed is about 75 mph.

"The hybrid system on the HH only operates at speeds up to about 40-45 mph. After that it is all ICE."
 
Not true. If you watch the display, you will see the electric motors kick in for short periods at higher speeds. I have observed it doing this at up to 70 mph. I have noticed this if you go down a small hill, the ICE will shut down. At the bottom of the hill, the ICE starts up again. As you climb a gentle hill the traction motor(s) will assist the ICE.

Thanks to all who've replied to this and set the record straight. I stand corrected. I was under the impression it worked differently - thanks.

All electric even above 60 mph by peralta

I have done this many times on my 2006 HH since I drive on hilly terrain. When I am going downhill and set my cruise control, sometimes the synergy drive sorts out and decides to do it in all electric mode even at 75 mph.

Is the ICE still spinning? (check the RPM gauge)

According to Toyota, the ICE comes on at and above 40-MPH so even if not in use, it will spin at idle. I believe Khdspyder confirmed this with Toyota last year.

Actual milage, 2008 HH by monte8

This past weekend I did a 180 mile round trip. Going out was east against strong (25-30 mph), direct head winds. I got about 24mpg. The return trip was with strong quartering tail winds (I was driving generally west, the winds were from the southeast). I got 33.6mpg. Overall, the round trip was 28 mpg. This is in a 2008 HH with only 2900 miles.

Does the '08 model have good acceleration? I don't mean "racing" speed but good acceleration to freeway speed?
 
It looks like Toyota did listen to early adopters and really made the car efficient. I am envious of your 33+ MPG!

The '08s are slower than my '06 Hh but they can get better mileage.
Mine beat a Jeep 5.7 Hemi in an 1/8th of a mile stoplight launched street drag.
The traction batteries have to be fully charged and the preferred technique is a firm steady press on the pedal. There is torque steer.

I am happy with it. I believe that the LA Times review by Dan Neil reported 0-60 mph times of about 6.7 seconds.
