| anthonyp,thanks for the weight.It is lower to the ground which occasionally could limit you on crummy unpaved dirt roads.Still,you can avoid them,but no midsized SUV can get 32 mpg hy(not the HH or RX400),and most are having a very good day when they get an honest 20 mpg hy.-thanks to your low ride.Thanks.Charlie | |

Replying to: anthonyp (Aug 10, 2005 1:19 pm) ->the amount of electrical energy required to keep ALL the electronic "toys" running. It's hard to compare one car to another unless you know this figure, and it is more apparent when you are at a red light. This means your engine may have to run at a particular load to generate enough electrical energy for all the electronic systems. Thus you'd see your mpg drops at a red light, one car more than another. I know this because a few years back, there was a huge discussion among automakers on whether to go from a 12v electrical system to a 42v electrical system. They quoted that older cars only need 5kwh to power electrical systems and newer ones, because of more toys inside (electrical power steering, abs, all sort of sensory systems, front radar for speed controls, sound systems, etc.) would need over 12kwh. That's the level electrical power consumption that older generators (pulled by engine belt) have to produce, and they do that inefficiently. A move to 42v generator and systems would be much more efficient. All that is to say that different cars have different electrical energy requirement, which is a function of electrical systems and the number of systems in the car. And the ICE has to drive a generator to produce that power. So by definition, a luxury vehicle (means lots of toys) should always has worse mpg than an economy car like a Prius, on the electrical consumption aspect alone. The obvious and major aspect is the vehicle weight. |

Replying to: dewey (Aug 08, 2005 6:08 pm) The quote from Toyota surprises me very much and I wonder if it is authentic. I live in Tokyo, and recently I visited a Toyota dealership (where they sell both the Prius and the Harrier Hybrid which is the Japanese name for the 400h). The Prius and non-hybrid Harrier are both available on relatively short notice, but the waiting list is so long for the Harrier Hybrid that the dealer said he could not get me one until next January at the earliest. He tried to sell me on the non-hybrid version. The area I live in is a very expensive party of Tokyo, so maybe maybe people here have more money to throw around, and other dealerships have more availability of the hybrids. However, if there really was a glut of Harrier Hybrids here in Japan, you would think that one of Toyota's biggest dealerships would not have a 5+ month waiting list. I didn't enquire about the Highlander hybrid ... actually, I don't think they had one. The dealer showed me information on all of the hybrids they have available: Prius, Harrier Hybrid, and the Alphard hybrid which is a pretty snazzy mini-van that I don't think is available outside of Japan . |

I took my new 400h with 900 miles on it in for service. It was pulling to the right a bit. They replaced the left camber bolt, which reset camber to 0.0 whatever that means. And they did an alignment. Everything works great now. Also, I noticed my hwy mpg jumped from 23-24 to 26-27 (AC set at 76). Not sure if that was related. I was happy to pay the premium for a hybrid when I bought the car, but now that oil is at $65+/brl, I am starting to think I made the economical decision. |

Can anyone tell me why, when I depress the brake peddle, that left-most dial's pointer dips into the blue zone most of the time, but sometimes doesn't seem to budge? Is regenerative braking variable, a function of the battery's charge? Or would this be a problem, and perhaps one reason I'm only seeing 19-21 mpg? I'm just curious. Overall, I like the car's performance-- despite its disappointing mpg and nagging "road crown" (dealer's explanation) steering-- and luxury. I'm hoping cooler weather and a broken-in engine will improve my mpg... Thanks for any thoughts.

| Hey, eman5 check mydquin's post.Yes,you could get better mpg if the front end was mis aligned and was "scrubbing".Thanks,CHARLIE | |
| Am sorry to report the bmw get twenty four and a half mpg at mid to high seventies..I am in the mountains of N.C so I took it down and up..Going down thirty or so coming back average the above...Remarkable how much it drops at the higher speed..Anything over seventy or so is poor....When I return to S.C it will be two hundred fifty or so miles and we`l see /// It is fairly warm so air conditioning was on at the low seventies....Yesterday`s trip was on the back twisty roads and really never aboce fifty or so and mostly in the mid forties as to other cars....Tony | |

| It seems most of the recent comments about the 400h relate to gas mileage. Mileage aside, how do you like the performance (torque, handling, etc.) of the 400h? I am interested in buying and would like to get the whole picture about the vehicle from those that have been fortunate enough to already own and operate one. Leaving mileage out of the equation for the moment, is the 400h fun and spirited to drive or no big deal in that regard? Thanks for your insights. | |
