Greetings: 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. Regards - M. J. McCloskey |

On my third tank of gas, 800 miles in. Mileage was roughly 21 mpg the first tank, 20.5 the second, 20.2 on this one. On the highway it gets up to about 24-25 mpg but in the city it's between 20 and 21, and most of my driving is in the city. This seems much lower than almost everybody else is reporting?!? 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. - adam |

We bought our Highlander Hybrid in December and have been getting progressively worse mileage. We have gone from 26.8 to now 20.2 (on our 5th tank). The dealer says it is related to cold weather. I would have not bought the vehicle if I knew that was the case. Could it be something with computer, battery. etc...? What is the best source on the web for Highlander Hybrid information? Thanks in advance, all comments appreciated. Steve

Replying to: desertfox1 (Jan 29, 2008 8:54 am) 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. - adam |

I reside in Alaska, and purchased my vehicle new in Nov. 2007. My gas mileage has been abysmal. According to the dealership, all systems are functioning within normal perameters. However, something is not right. Here are stats that I have gleaned, based on mileage posted in the car's center panel, and my own MPG computations: 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... AKDeeDee |

Replying to: akdeedee (Feb 01, 2008 9:36 pm) 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.
