". . . What are the consequences of larger wheels (19 vs 17): Obviously it gives one inch extra clearance, which could be good sometime. . ."
 
The larger wheels do not give extra clearance. The only advantage is that the lower profile tires (45 series on the 19" vs. the 55 series on the 17") will give "better" handling. They will also wear out sooner and provide a harsher ride (due to the shorter sidewalls). The wheels (also due to the shorter sidewalls of the tires) are more likely to be damaged by road hazards (potholes, debris, etc.). The main purpose is that some people think they look good.
 
Re-think the review camera. I have found that because of the tint on the rear windows I cannot not see anything out the rear windows when backing up at night. The camera gives a great view, at least of the close area. It is great for parking, I can bring the rear bumper up to about 3" from the bumper of the car behind me without touching it, and still see a gap using the camera.

It is possible the "one inch clearance" is referring to the inner wheel, not the tire diameter. This would give more cooling airflow to the rear motors.
 
I agree about the camera. I sure wish I had one on my Tacoma so I wouldn't have to get in and out so many times when I hook up my trailer.

HH and snow by stanwagon
Feb 10, 2008 (1:48 pm)

We are having very above average snow year here in the Colo mts and so far the HH is behaving well. Not quite as good as the 1994 Explorer with its low range, but it has been fine in very heavy snow. The real test will come this summer on some of the rough roads to trailheads... the power is there, and the clearance is probably the equal of the Ford, but will the lack of gearing keep me away from places I am used to getting to? We'll see,

We are in Northern British Columbia with plenty of snow and very cold temps. Do you have any experience or idea yet how much of a mileage hit you are seeing in sub-zero temps? We usually reckon on about 25-30% drop in mileage for our ICE vehicles during the 3 heavy months Dec-Feb. Is the HIHY comparable or worse?
FWIW we will be using the new vehicle almost exclusively in short to medium haul city driving.

MPG in cold weather by stanwagon
Feb 11, 2008 (1:28 pm)

I have only had the vehicle in the winter, but I have experience with the Prius for 3+ years now. In summer, Prius gets 50 mph no problem. In winter it gets 40, except when I am working in St Paul, Minnesota, and driving just 2.5 miles to work each way. Then the mileage takes a big hit because of the short hops. 32-35 mpg is typical for Dec. in St Paul (unless we go somewhere on a longer trip). I imagine the HH willl be the same, percentage wise. Right now I am getting 24, but I try to use it only on snowy days. I believe it will get 30 in the summer.

So do the HY's not do well with short drives? My understanding was that short distance city driving is their forte. Am I wrong on this, or is it simply an issue of short trips are always bad for mileage - ICE or HY? Were you using a block heater? I've read that can significantly improve performance of the HY.

Yes short trips are bad for all ICE vehicles. Hybrids are primarily ICE vehicles. Hybrids do very well when the entire vehicle ( ICE, cabin, catalytic converter ) are at optimal operating temperatures. This allows the ICE to shutdown or shut off for periods of time. The battery and motor can then power the vehicle alone. But the ICE has to get everything up to temp first.

Fuel Gauge and Cruising Range by p38light

Why is that the Fuel Gauge and Cruising Range move more slowly from full to half then they do from half to empty or zero? I've noticed this on several cars I have owned, both Toyota and domestics.

Toyota hybrids are designed to get really GREAT FE in city stop and go traffic in comparison to "normal" ICE vehicles.
 
If there is no opportunity to recover energy "stored" in the mass of the vehicle via it being in motion then the Toyota Hybrid synergy drive system has very little advantage. Energy recovery via regenerative braking occurs only during coastdown and braking periods. For mostly freeway, primarily cruising at a set speed, you would be better off with a non-hybrid vehicle.
