Replying to: pf_flyer (Jun 12, 2006 5:18 pm) The best highway mileage has been 27.9 mpg actual and 29.0 mpg, digital readout, driving at 70/55 mph with AC in hills/mountains with a moderate tail wind. The worst highway mileage has been 21.4 mpg actual and 22.4 mpg, digital readout, while driving at 77 mph with AC in hills against a stiff wind. Best around town mileage has been 29.2 mpg actual and 30.7 mpg digital readout while driving in and around town with max of 55 mph speed and no AC. A driving experiment I have tried on a 55 mile isolated flat country road route on a calm day has yielded my best interval mileage of 36.6 mpg, digital readout. The technique involved starting with a full tank of gas and driving 55 mph on cruise control until the computer graphics icon showed the battery charged to midway of the plus sign. Then, coasting to 37 mph and setting the cruise control and running on the battery until the engine kicked on, kicking down the cruise control to 36 mph, running on battery until the engine kicked on, kicking down the speed to 35 mph and repeating running on battery. The runs were 3-5 miles at 55 mph charging the battery and 0.7 to 1.2 miles on the battery at 37-35mph. About 10 of these cycles were required to make the 55 miles. What was interesting was that the average mileage increased from 30 mpg to 36.6 mpg, digital readout, over the 55 miles and was still increasing when finished. The experiment showed me the mpg potential of the vehicle but, for safety reasons, I would not recommend driving this way in traffic. I can not wait for the PHEV version of the HH. |

Hi folks: I bought a new 2007 HH Limited AWD without nav on March 30, 2007. I've driven it almost 2000 miles, filled up the tank (no top off) three times and average 30 MPG (miles driven/gallons used)in combination city-freeway driving. I follow the "pulse, feather, glide" technique mentioned in this and other forums. And, just as an experiment, I am limiting myself to 55 MPH on the freeway. I am always looking for ways to improve mileage. Any suggestions? Happy driving, Inndriver |

Replying to: inndriver (May 14, 2007 9:52 am) If by freeway, you mean interstate (65-70 mph speed limits), I would be very concerned about your safety and those around you. Than is much to slow to be safe in traffic going 70 (and probably plus)

| In Puerto Rico's weather and constant traffic jams I'm getting 21.6 MPG. On the highway is not much better. | |

Replying to: mevande (May 22, 2007 12:14 pm) If the driver is in the rightmost lane, he or she is doing something perfectly legal and being courteous. Maximum speed is 65, not minimum speed. Legally and theoretically speaking, no one has to go 65 but almost everyone does and more. Trucks and cars with trailers are by law, limited to 55, at least in CA. So 55 is perfectly fine in the rightmost lane. If the HH is doing 55 in the fast lane or other lanes other than the rightmost lane, then I will agree that it is a problem. Taking this the other direction, I drive 60 in the rightmost lane and crazy drivers would zip up to my butt trying to push me along. That is plain stupid. I have seen GM Envoy towing a large 3-horse-trailer zipping along at 70-mph. I have seen delivery trucks going 75 in the leftmost lane. I have seen Lexus monster SUV going 80 weaving in and out of other lanes. All those morons are much worse than a HH driver doing 55 in the rightmost lane. If doing 55 mph buys me 30-MPG versus 28-MPG and I can do it safely without impacting other people, why not? What is not to like?

Replying to: cdptrap (May 22, 2007 5:43 pm) Personally, I would never drive less than 5 under (or over) the posted limit. The biggest danger on interstates is coming up behind someone to fast (whether that car is speeding or the other car is to slow - both pose a hazard) and not having any place to bail out. Bad for both cars.

Replying to: desertfox1 (May 24, 2007 7:05 am) There are more speeders on the road than slow ones. There are more reckless stupid drivers out there endangering everyone else than slow ones too. So why focus on us penny-pinchers?  That said, I am finally pushing 29 MPG with summer gas. Yeehaa! |
