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 The EPA tests are very outdated, and in an attempt to get them closer to what the people are actually getting, they (EPA) are adjusting the figures down for 2008+ cars.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.

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. |

2006/6964A HH 4WD-i V6. Bought June 1, 2006 Odometer now has 10595 miles. According to my glovebox log book, we've put in 448.5 gals into the SUV. Calculates out to 23.6 mpg. Mostly rural city type driving. Sticker numbers in very large eye-catching font says 31 city and 27 highway. I'm a little disappointed in the results. |

"Mostly rural city type driving. " Huh? That is two different driving cycles. Have you attempted the various gas saving techniques?
