    That the Prius would get better mileage without the batteries; Toyota would have built it without the batteries if that were the case.

    The batteries take the strain off of the ICE, producing better mileage.

    Note that I did not state that without the batteries the city MPG would be better. With stop and go traffic in the city the batteries get recharged for "free" during slowing and braking. And the "turbocharging", boost, provided by the batteries to get up and moving more quickly are also a definite asset.

    Driving at a "constant" 70MPH for 3 hours is an ICE only asset.

    IMMHO the Prius needs a switch to make the batteries off-line while cruising.

    I've had my 2004 Prius since December and have about 2000 miles on it. I live in Northern California where we've been having summer-like weather for the last few weeks. So, weather isn't the cause. I consistently get 36-38 MPG, which I consider very disappointing. That is combined fwy/city driving. I have read other places that some owners feel that the car has "taught" them to drive better.
    1) I don't ever see any difference in the mpg, based on doing anything I'm doing differently so where would someone get feedback from the car that helps them to drive better?
    2) I tried to use the manual to learn better how to operate the car but found it (in all aspects) almost impossible to follow/read. It's written by someone for whom English is not a first language and is filled with "caution" and other warnings. Has anyone had any luck in getting a manual written in American English?
    3) I'm unclear about the use of the 12v plugs. If I plug something in (i.e. a laptop) and keep it on while the car's engine is off, will I run the danger of depleting the battery?

    Would appreciate any thoughts/suggestions.
    Thanks

    The "accelerate slowly" misconception gets most new Prius drivers. They assume driving conservatively will save gas. But in reality, that actually wastes it.

    When the light turns green, generously drop the pedal. (But don't floor it, obviously.) That "BRISK" acceleration will make a world of difference. And since it is the way many people drive anyway, you may not even have to change driving habits.

     
    The next serious problem new Prius owners encounter is tire pressure, they simply aren't aware of its importance.

    You need an absolute minimum of 35 PSI in front (33 PSI in back). Softer will kill efficiency, as well as the tires themselves.

    Increasing pressure (always with a 2 PSI bias in front) will both increase MPG and tire life. So it is very worthwhile to give it a try. My preference is 44/42.

     
    Another efficiency factor, that is quite often overlooked, is oil level. You'll discover dealers squirt way too much oil from the bulk barrel into your engine (despite that being warned that it could cause damage in the owner's manual). Some owners have even reported having almost a entire quart over the "Full" mark. MPG will suffer as a result. Have the excess drained out immediately!

    1/4" below the "Full" mark is the ideal level for the oil.

    This last one, may or may not be obvious...

    AVOID SHORT TRIPS!

    Since heat is needed for the emissions system, the engine must until heat is available. That means during the first 5 minutes of driving, the engine may not shut off.

    In other words, you don't really get to take advantage of the hybrid system unless your drive is longer.

    And these facts should be blatant...

    Wait for break-in to complete.

    Switch to synthetic oil.

    I think you get sample variance with any vehicle, some large SUV owners complain about 8-9 mpg even when EPA numbers are 13-16 or so.

    I'll buy that the MPG will be lower, but telling people to drive more to get better milage is counter productive.

    Driving 20,000+ miles a year (when it isn't necessary) at 50MPG is worse than driving 12,000 miles a year at 40MPG, right?

    Hmm, I'd been interested in hybrids because I mostly do driving in town (traffic, lot of red lights).

    Plus my commute is 1.1 miles. So maybe this kind of distance isn't good for hybrid fuel efficiency?
  • ateixeiraateixeira Posts: 72,587
    carguy: I don't think they meant take longer routes, just avoid driving short ones, maybe walk or bike to those close-by destinations.

    Or to COMBINE trips. Running several errands at once, rather than individually. (That will usually save time too.)

    Yes, efficiency will suffer to the extreme in that case.

    1.1 miles is absolutely HORRIBLE on any type vehicle. The water vapor that builds up in the exhaust system never has an opportunity to get pushed out, so it ages at a very accelerated rate.

    Also, 1.1 miles is so short of a distance you really should be walking. I did for countless years, even in the dead of Minnesota winter. (Heck, when I go out for a short bike or rollerblade in the evening, I do at least 10 miles.)

    > bike, or walk, etc

    Maybe you don't have families. Parents take kids to school and pick them up. You drive to sports practice. You do the middle of the night urgent care runs and then to the all night pharmacy to gets meds when kids are sick.

    If you are saying the Prius isn't a family car, that's one thing, but I don't know very many parents that get by in life without having to make short trips a good part of the time.
  • ateixeiraateixeira Posts: 72,587
    Try some other ideas - like carpooling with other kids in school, which is what we do. Or I'll drop them off on the way to work.

    Nice thing you'll find is that you end up with a lot more free time!

    I wish DC would make Rock Creek Park and Clara Barton Parkway both HOV only. Maybe allow PZEV vehicles as well (the state of VA already does this).

    More real incentives like these would get more people to conserve.

    And I know just as many parents that are forced to run a bunch of errands all at once. What is your point?

    My point is to reduce, not eliminate. And if you absolutely positively can't, just be thankful you have such a reliable car to support you lifestyle.

    A bunch of errands all at once? Yes, but you still need to go to a bunch of places that may take short trips to get to, even if you do them consecutively.

    I car pool, but have yet to see a Prius drive by with a passenger (granted I don't see very many of them around here).

    i test drove the prius last month. entering the dealer parking lot at the end of the test drive, the front of the car sraped. What was more interesting was that just before the back tires went up the driveway, i heard scraping again. i did enter the driveway straight instead of at an angle. maybe the driveway was a little high. or is the car really low? there were 4 in the car including myself. anyone have this problem with higher driveways or with speed bumps?

    A short trip is one where the engine is COLD even at the conclusion of the drive.

    Since the engine doesn't cool off right away and the fluid in the thermos remains HOT for several hours, you can shut off the car in between and it will still count as a single trip.

    Either the bump was rather unusual or the car simply wasn't prepped properly (there's a lot of plastic that gets added to the car after delivery to the dealer).
