13,700 miles
95% highway
Now consistently getting more than 30 MPG for the last 2 months.
I noticed that in some city trips I can get as high as 40+ MPG.
I am very happy, it is much better than the mileage of my previous 2000 and 2005 Hyundai Elantra's.

I have a new 2007 hybrid 6 cyl 2WD which has close to 5000 mi and it is very annoying to have the car shake/jolt when the gas engine engages or disengages!! If i come to a full stop in traffic the car shakes when the engine goes off...as if the car behind you bumped into you!! And as bad... when I take off slow... it jolts again as the gas engine kicks in?? In taking off it feels as a transmission jumping into gear would. Now I believe this has to be the gas engine, but not really sure?
Is this something that is normal for toyota hybrids?? I do not remember the test ride SUV riding like that or I would not have bought one. ....
thanks for any help or thoughts, especially if others have seen this.
Thank-you.
Was it suddenly colder last week?
Question - how do you know exactly how many gallons you've used ? I would like to run the tank down to know for sure but then I'd risk running out of gas. Is there an indicator of how much gas I've used or what's left somewhere that I'm missing ?
You simply fill the tank all the way up to the pump shutoff, then run the tank until it gets to "E". At that point, return to the SAME pump and fill up the tank.
BTW, if you had "serious"headwinds and you were doing 75 MPH, you might have had an actual speed of 90 MPH affecting the cross section of the HH. That will cut down on MPG with such a high profile vehicle.
Any feedback is appreciated! Thanks.
My daily commute is about 2/3's two lane highways (40-55 mph), with some stop and go, and 1/3 freeway driving. The round trip is about 26 miles total. I'm almost through the first tank and the average has been steadily rising since I got it and is now at 25.0 mpg. That includes the dealer introduction to the vehicle in which the system was left on for about an hour with the engine cycling on and off as it saw fit and a few mornings starting up from below freezing with the vehicle left outside for the night.
So far, I'm pretty impressed with it, including the mileage, which should continue to go up as the engine breaks in over the next few thousand miles.
Good luck with your decision.
Note: If you just let the gas pump cut off automatically, you want get an accurate reading because depending on the angle the vehicle is sitting it may cut off and you can still put anywhere from 2 to 5 gals more in the tank to fill it to the top.
When you press the Fuel Filler Door Release button, the Owner's Manual says that it may take up to 10 seconds to release the door and that the Multi-Function Display alerts you to when the vehicle is ready to be refueled. It also mentions that it is releasing pressure from the system and another section in the manual, about unusual noises from the vehicle, mentions that you may hear a hissing sound about 5 hours (I think this is the correct figure) after shutting off the vehicle. It says this is a leak test for the system. I know that this must be part of the SULEV (Super Ultra Low Emissions Vehicle- Zero evaporation) compliance system, but I'd like to know more about what it's actually doing and how it works.
Does anyone else know more about the fuel system in the 2008 HiHy and what it's acutally up to?
Does the previous model HiHy also work this way?
Does it normally operate under pressure?
Inquiring minds want to know!
After the first fill, with a warm engine on a easy highway, the computer display shows 29.2 mpg for the remainder of the trip (an additional 83 miles).
I was driving in the Econ mode.
I expect that this will improve with further break-in of the engine components.
We're in a fairly hilly portion of Oregon doing mostly errands, but I'm only averaging around 21mpg.
Anyone else have experiences with the 2008 they can share?
I am from Edmonton and I bought HHL-06,19K miles with NAV from USA. I am trying to convert convert digital odometer reading from Miles to Kilometre and to degC.
Do you have any idea? I contacted local Toyota dealer and they cannot figure out this change to Metric without changing odemeter cluster.
Any help is appreciated.

Steaman
The vehicle passed both federal and provincial inspections easily, no repairs or mods at all.
How are you finding the vehicle ? Over all I am very happy, but the magnitude of the decline in fuel efficiency in colder weather has surprised me. With my mix of driving I was getting about 25 mpg when the cold hit and now I am about 20% lower.
I have a 2007 HH Limited FWD and have also noted lower MPG due to the cooler temps. I was averaging 28/29mpg in the Spring/Summer but have dropped to 25-26 here in the mid-Atlantic region (VA). I believe this is due to the ICE running more frequently to keep the engine temp up. My previous vehicle (non-hybrid) would also incurr a drop in overall MPG when the temps dropped in Fall & Winter. Still, my MPG is far better than a similar sized vehicle and I am quite pleased overall.

It's a Limited, if that matters. Cold tire pressure is 34 psi. I'm driving in Econ mode and trying to accelerate smoothly and slowly. The terrain has a few hills, but nothing dramatic, and I go down the same hills going the other way.
I live in the Seattle area--I saw somebody in Oregon also reporting low mileage. Maybe something about the Pacific Northwest? Do people think this is something where I should bring it to the dealer and ask them to investigate?
Thanks.

Thanks in advance, all comments appreciated.

One thing is, the car is parked outside both at night and during the day. The temperature has been in the low 30s at night, high 30s or low 40s during the day. And I'm only driving about 20 minutes each way to work, so maybe the car never has a chance to warm up.
Thanks.

City Driving: 11-12 MPG, as compared to the EPA average estimate of 27 MPG, which is a 54% difference.
Highway Driving: Around 22.5, which is only 9% difference than the EPA average estimate of 25. I could live with that, but most of my driving is within a city!
Combined City and Highway Driving: Seems steady at 15.7, as compared to the EPA average estimate of 25: a 40% difference.
Is anyone else on this post driving a 2008 Highlander Hybrid in cold weather conditions? I wish I had read the owner's manual BEFORE buying this vehicle, because it states very clearly that the EV-Drive does not function in temperatures under 32 degrees (F). None of these details were shared with me at the time of purchase, and I am extremely frustrated.
Thanks for any information that you can share...

The decrease in mileage in the cold months is supposedly due to numerous factors including winter oxygenated fuels, snow tires, heating up the car before driving, using the heater on high while while driving, decreased traction from slippery/snowy roads, or not topping off tire pressure in cold weather, and decreased performance of the hybrid battery in cold weather. All these factors would be expected to affect a non hybrid car equally except the effect of the temperature on the cold hybrid battery. Of course this is all anecdotal and not backed up by any real data, I don't think anyone has done a study on it, if Toyota has they're not talking.
So the question is how much of the decrease in mileage is due to impaired performance of the hybrid system in cold weather. I have friends with a non hybrid 2005 Highlander who claim they get around 17 MPG all year round but they don't have a cumulative gas mileage readout as in the hybrid so they are guessing. I was never aware of this magnitude of winter fuel economy loss before I had a hybrid but I didn't have a fuel mileage gauge before either.
I think this is an important piece of information for those of who live in the arctic and want to decrease our vehicle emissions all year round not just in the summer. Toyota's hybrid market is so small here it's probably not important enough for them to study.
Maybe we need an Alaska hybrid users group to explore the question of whether the additional expense of a hybrid makes sense in this climate given current hybrid technology.
stats: 07 HH AWD, 20k mi, 30mi commute (mostly hwy, lite traffic). best tank: 32, worst: 22

dunno bout you, but all of my vehicles get worse mileage in the winter - I live in Iowa, so have much the same weather as you. My Tundra pickup goes from 17-18 mpg summer to 12-14 mpg in the winter. I'm driving an 06 Highlander Hybrid - well broken in with 55k miles, and while it gets as low as 22 mpg in the winter, now that winter has finally broken, I'm getting astounding mileage.
I have been getting consistent 27-28 mpg tankfulls; but now that gas prices have become ridiculous, I have started driving slower on trips. That has paid a huge premium; just by slowing to 65 for my Interstate driving, I've noticed that the battery is operating a lot more; I'm also seeing concrete results at the pump - last fill got me 31 (!) mpg. Subsequent refill still came in at 28 - so probably a valid reading.
Slow down a touch, and these hybrids are great - the electric motor just doesn't have enough power to deal with the wind resistance at high speeds, and consequently, mileage suffers.
I live in NE North Dakota. Much colder than Anchorage, AK (I lived there for 3.5 years), but warmer than Barrow, AK (3 years there).
My prior car was a 1998 Ford Contour w/2.5L V6. My gas milage dropped about 35% in the coldest part of the winter with the Contour. I saw a similar drop with my '08 HH. Installing a block heater helps a lot. But when it drops to -32 F, it takes time for the engine to warm up to efficient operating temperatures. BTW, I do not let my car sit and run to warm up, except for extreme cold weather (fogged/iced windows are dangerous), so I do not waste gas that way.
I can't stand to drive my non-hybrid anymore.
Almost constant driving one person and luggage, from Minneapolis, MN to Oshkosh, WI
30 MPG Summer
27.5 MPG Add a second person and more luggage
Going speed limit on major roads
Mixed driving (city/highway)
23 to 25 MPG Driving in Minnesotan winters drops to, sometimes slightly higher
25 to 30 MPG Driving in "warmer" months - (closer to 30 MPG if I can "drive for mileage)
Driving habits:
I monitor the air pressure in the tires; the Scangauge II is in gauge mode most of the time (watch engine RPMs, throttle position, engine load, and timing).
Highest even seen - 32 MPG in mixed city/highway
To get these numbers, I need to drive, watching ahead for stoplights, slowing down before. Unlike other cars, I gently "ride" the brake, which initially kicks in the re-generative braking. I tend to gradually accelerate, except for unusual traffic conditions. Kicking in the turbo mode of the HH dramatically reduces gas mileage, although useful when merging into heavy highway traffic.

Scott
This would be incorrect. The hybrid system on the HH only operates at speeds up to about 40-45 mph. After that it is all ICE.
The phenomenon you are describing here applies to ALL vehicles, we are just too impatient to actually GO SLOWER. EVERYONE would see a benefit from doing this.
The above statement is also incorrect . The ICE can kick in at any time, from 0-mph to blast-off and the batteries can kick in at any time from 0-mph to blast-off.
On flat ground, it is possible to go from 0 to 40 MPH on electric-only. If there is enough charge and the ground remains flat, I can maintain 40-MPH for a very long spell. A good stiff tail-wind helps.
On downhill runs, the battery can go even further depending on desired speed. On steeper downgrade, even on freeways, the battery can provide all the power to maintain 65-MPH or 70-MPH (on really steep grade) while the ICE just idles. We see this all the time driving I-5 in Northern CA. The car is cruising downhill at 65-MPH and the ICE is madly charging the battery or the battery kicks in to give some power to maintain downhill speed. By the end of a run, the battery is all green (full 8 bars).
On a climb, the ICE kicks in and the battery will also kick in to boost power. The battery provides instant torque in such cases and the car just rockets up a grade like it is a V8.
The ICE and battery pack work together through all speed ranges. There is NO "cut off" where the ICE takes over completely without the battery pack. At least I have never seen it on our '06 HH.
Just want to clarify.
No, I'm afraid YOUR statement would be incorrect. I own the FEH, which is similar in drivetrain design to the HH. The electric motors can provide boost at all speeds; the only imitation is the state of charge in the battery.
The design requires that the engine operate above 40 MPH, but this actually means only that the engine has to spin, not that it has to consume fuel. I think that on a downgrade with a full battery of vehicle will use the drag of spinning the ICE to bleed off excess electricity from the generator. At least, this is my understanding.
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.
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.
Is the ICE still spinning? (check the RPM gauge)
It looks like Toyota did listen to early adopters and really made the car efficient. I am envious of your 33+ MPG!
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.
