    Well then, hypermiling it should be easy. :) If you were closer I would trade you cars for a week to run some tests.

    if YOU were closer, i would trade cars with YOU. although, why anyone would leave cali to come out to the frozen tundra, i have no idea. :cool: the question is, is it efficient to run the motor, batteries, connectors etc. upto a higher speed and glide back down as we do with the ice? frankly, i'm surprised we haven't heard more about this, especially from japan.

    With careful, conservative driving it is possible to get 18 miles (ROUND TRIP) in EV mode. I did not say ONE WAY, because that depends on elevation change and perhaps other factors.

    My commute to work is 17.7 miles round trip and I usually have about 0.5-1.0 left in the EV range. To be fair, my commute is thru back roads with average speed of ~30mph, with three stop lights on the way. This is only on the days when weather is good and I don't have to use any A/C.

    i hear you. mine is 15 miles and i usually get home wit 2-3 left. same thing, mid 20's mph average. i can use a/c at 79 and still pretty much do this. no question 18 is possible. some have gotten over 20 in stop and go bumper to bumper on the highway.

    Unfortunately, with my commute, I think I would be shot if I tried to get 18 miles out of it. I know how to hypermile and can do it in the PiP but it is harder than in my 2008 gen2 (seems more touchy). In my commute, one way is slight downhill 9 miles and the return trip is exactly the opposite - slight uphill the whole way. (San Tomas Expressway for any who know Santa Clara.)

    Also, I don't know quite how to reconcile the comments here about getting 18 miles range with the comments about getting the same range whether driving aggressively or not. Theoretically, it just seems to me there has to be an energy loss if the energy comes from the battery and goes to the wheels and then goes from there back to the battery through regen. So, I have my doubts on the 'same range regardless of how aggressive the driving' comments.

    But, in any case, I've tried hard to get 18 miles range and I don't think I can do it safely where I live. I believe I could get 14 max (I get 12 to 13 now - I can get 12 even on the freeway at 62-64 MPH for 4 of the 12 miles.).

    The only other way I know of to 'extend' the range is to let the ICE warm up and then hypermile/stealth drive while in HV mode - I can do this regularly and get another 2ish miles of EV range but the ICE had to warm up to do it and the whole point is to avoid that....

    I think the main point with "aggressive" driving is that you have make sure you don't end up going any faster when driving aggressively than when not. Driving "aggressively" is just changing how quickly you reach the same target speed, and the claim is that it does not have a whole lot of impact on range. I agree that slowing down and speeding up a lot would hurt range, due to conversion losses.

    driving aggressively does have some impact on range. and elevation does as well. and pip2012, genIII glide is definitely more touchy than genII, despite what F8L says.:p

    Gliding is more difficult in the GenIII but you get used to it once you figure out what to look for. Now I can hypermile my GenIII much better than my GenII. Just make the HSI bar disappear or have it in the first 1/4 of the EV section and you're gliding (or warp stealth). ;)

    why is it not using battery upto the first 1/4 of ev?

    It is but just barely and not enough for acceleration. It's just enough energy to cancel out regenerative braking and the drag associated with that. The closer you can come to making the HSI bar disappear the less energy you will use but even up to that 1/4 mark you are still using very little. With practice you won't have to hold it that high. It helps to keep the car in Eco Mode and not wear a right shoe if you need more sensitivity.

    I use neutral all the time. What are peoples opinions of using neutral compared to trying to make the bar disappear?

    For me, its so much easier to put it in neutral. One thing to be sure of though, if the ice is running, make sure you leave it in D otherwise you are wasting power. The ice sends power to the battery when it is running but not if your in neutral.

    Yes, as a matter of fact I did check around a little on this and posted this a few weeks ago:
