Averaged 29.1 mpg for the last fill up, a little over 1/3 of a tank. I did use P and G and golf cart speeds in an attempt to drain the traction batteries. |

Replying to: inndriver (May 14, 2007 9:52 am) I recently purchased a ScanGauge II, which plugs into the OBD II port under the dash. It shows REAL TIME mph, mpg, engine temp, and a bunch of other factors, plus it will show you your trip mpg and tank mpg among other things. I find that watching it, I can choose whether to rev up and use more gas or not based on real-time performance numbers. It has adjustment factors for when you fill up your tank each time so you can match the pump's readout. It's fun - and I am not a high-tech person! Also, I plan on installing a block heater, as the worst mileage is in the first 5 miles when the car is warming up. The block heater can be plugged into an outlet with a timer, so it will go on 4 hours before I drive it in the morning. Toyota dealers can get the block heater for you (part #00213-00644), but they'll tell you that you don't need it. Of course, you don't need it to help start your car - but it will improve your mileage, especially if you live in a cold climate like I do (Wisconsin). Finally, read tips & techniques on cleanmpg.com There are some great suggestions there. |

Replying to: sponda (May 27, 2007 6:05 pm) If the freeway is hilly, if speed is over 65, 70 or 75 or 80 or changing constantly, if tire pressure is too low, if engine condition is not great, if the car is heavily loaded with people or even just one driver with a load of things in the trunk, then all these factors can combined to impact the MPG. I believe the HH software is designed to work well at freeway speed up to 60-MPH. It does not seem to do much at 65-MPH, kind of disappointing if this is true. When our HH has a good solid charge, the battery kicks in often to help the car along at 60-MPH. We see it on the energy flow screen all the time. On somewhat flatter terrain, this often gives us 30-35 MPG (intermediate only) for the 32+ miles trip one-way that we take. At 55-MPH, it can do even better giving us up to 37-45 MPG (intermediate) for the 45+ mile trip we take one-way. Unfortunately, once we go over 60 or once we get to 65-MPH, the battery kicks in less. May be aerodynamics and physics is forcing the ICE to run more, may be the software is still stuck in the old days of 55-MPH Speed Limit rather than the 65-MPH limit  . If I live in flat country like NV or AZ or just flat areas of CA, our HH can easily get up to 30-MPG if I just go 60-MPH on freeways (not on I-5 though) and nice and easy on city streets.

Replying to: sponda (May 31, 2007 7:03 am) THEY (Toyota) don't say it gets any gas mileage. The United States EPA tests the cars, and the manufacturers are required to post what the EPA ratings are. The EPA tests are very outdated, and in an attempt to get them closer to what the people are actually getting, they (EPA) are adjusting the figures down for 2008+ cars. For an eye opener as to how the tests are done, try searching the web for: EPA Fuel mileage tests.

Replying to: jbollt (May 31, 2007 7:54 am) Well, sort of. The EPA makes the testing rules, but most vehicles are actually tested by the manufacturers, not the EPA.

My 06 AWD Hihy with 10,000 miles is getting very good fuel economy, 37 miles drive to work. My scangauge reading was 5 MPG less than the actual MPG. I thought the hybrid system is not worth it, until I cross checked with actual hand calculation at the pump. Now that I know the actual fuel mileage, I am very happy. No other AWD SUV can touch that, except Ford escape but the escape is a 4 cylinder, less powerfull, slower, noisier and rougher. Regarding the scangauge, it needs to be cross checked against actual MPG. Since it is a little bit off. It reads 2 MPG more than the actual MPG in my Subaru outback. It is also 1 MPG less than the comptuter read out in my Sienna. |
