    Considering buying a Prius, but turned off a bit by the big discrepency between EPA estimate vs. actual MPG.
    I know you can't expect to get what the EPA sticker shows, but reading that some people get as little as 30 in cold weather, or that most it seems average in the 42 to 45 range is a bit of a turn off. Yes, it's a lot more than any other car (sold in the US), but if you advertise 60mpg and you only get 42 that's a HUGE difference.

    Here is an article in Consumer Affairs about this very same issue and it appears the EPA is officially lowering its estimate from 60 to 45: http://www.consumeraffairs.com/news04/2006...priius_epa.html

    consumeraffairs.com ("the journal of ambulance chasers") is just slightly less reliable than the Weekly World News.

    EPA is changing rating procedures for ALL cars, not just hybrids or the Prius.

    It has been posted that if you do the math in terms of consumption, not mpg, you will see the change is not really much more severe for hybrids on a percentage basis.

    I am getting 51+ with mine in combined city and highway hilly driving, and I think that is closer to the EPA estimate than most cars, irregardless if they kept it at 60 or lower it to 45. Some people are bound and determined to spead bad press about the Prius, even when they need to make stuff up.

    If you haven't read the story about Prius Taxi going 250,000 miles, be sure to searh our forums and read it. The driver says maintenance costs were substantially less than standard taxis.

    It seems you're allowing yourself and your emotions to be affected by the "advertised" number, rather than the comparison of what it does against any other car on the market in any given condtion.

    Remember, those other cars were also advertised at 28 or 30mpg, but in cold weather in short trips or at the very beginning of a drive they got WAY lower than THEIR "advertised" numbers.

    Just because someone says "60" don't get all bunched up when you get 30. The other guys say 28 but in identical circumstances they get 14. On average, overall, they get 20--nowhere near the 28. So? Did you complain about that?

    You've lived with this all your life, with every car you've ever owned and/or driven. The difference is, with those cars you expected it--and they didn't have little screens staring at you, displaying that "14mpg" right in your face. You were blissfully ignorant. And when you thought about it, you merely dismissed it as being unimportant.

    The same thing goes with the Prius. The laws of physics hold.

    Y'know -- anyone who hasn't already and is interested in this whole
    comparison with EPA and better fuel economy in general should go poke
    around CleanMPG and read the "Beating the EPA" article and related.
    Once people figure out how to ride the top of the efficiency curves
    for a given vehicle, the numbers just start to pop. This is real
    life, and in most cases normal, i.e. not freakazoid, driving style.
    Check it out.

    You have come to the right site to get the truth about the Prius. The EPA has had a faulty method of MPG testing (one that... belive it or not...., does not involve any driving, or turning the AC on!) Then there is a requirement to inform the buying public by putting these faulty MPG values on ALL car labels. Now the EPA is fixing their test methods, and ALL car MPGs are dropping dramatically to real values. In the article this EPA mistake has somehow become the "Prius's fault". Read it again knowing what you have just learned.

    When you look at the EPA "range" for similar vehicles, see what vehicle is at the top of this "range". (Hint: It starts with a "P" and is made by Toyota.) Now you should be turned off by the EPA and not the Prius.

    Thanks guys. I agree. It's A LOT to do with driving style. None of my cars have MPG reading, so when i rented once a car that did show current MPG, I was able to learn by driving it how to get the MPG higher. So this is a learning process and I'm sure the Prius can "teach" you how to improve your MPG. It is encouraging when I read so many people getting in the low 50s, that tells me if I learn the little tricks I can do that to.

    I'm almost sold. What I've decided is to rent it for a week, go on a trip around Cali, drive around Vegas all day too and that will make me decide whether to get it or not.

    I know for myself I consistly get over 50 miles whether in the city or country. But I will also tell you that I d always drive 1 to 3 miles per hour below any postred speed limit. I never "jack rabbit start" and always anticicpate red lights.

    Are you upset about the advertised EPA estimates for other cars as well, because they are just as far off percentage wise as the Prius? The EPA test does not accurately reflect real world driving conditions. However, it is the only apples-to-apples comparison that we have widely available to us as consumers.

    The single-most important factor with regard to the MPG that you will get on the Prius is trip length.

    It takes 5 minutes to warm up the car -- sometimes longer in colder climates. If all of your car trips are five minutes in length, you will get 30-40 MPG in the Prius, regardless of the year of the Prius. If many of your trips are around 10 minutes in length, you'll be one of the many people in the lower 40s.

    I have a 2001 Prius in Austin, Texas. Last summer, I average 53 MPG to and from work, which was 20 miles away. Now I'm working less than one mile away, and I am getting around 35 MPG. I even turned the screen off because seeing 35 MPG after seeing 50+ for over a year is depressing. :D

    The second biggest contributor to MPG rating on the Prius is the usage of the A/C or defogger. The defogger because Toyota knows that seeing out the window is more important than fuel economy, and the A/C because we all know that even small A/C units suck up ridiculous amounts of energy.

    So if someone tells you they get 35 or even 45 MPG in a Prius, you know they are doing a lot of short trips in the car. Taking short trips and using the A/C the whole time -- sometimes very necessary in some climates -- they'll get even worse. That's all there is to it. Note that I didn't mention city driving/highway driving, driving slowly, etc., as most people mention in these conversations, because THESE HAVE NOTHING TO DO WITH IT. Beyond what I have stated above, the only thing you can do to squeeze out a few more MPG is the pulse and glide techniques (which do work and will add 3-5 MPG for any driver provided the car has warmed up and the AC isn't running).

    As for the EPA ratings, unless they have shortened their tests to under 5-10 minutes long and/or have started running the A/C or defogger during the tests, the Prius will still rate higher than what most Prius owners get.

    Since the MPG is related to trip length, a lower MPG is not a show-stopper on the Prius. You're still using less gas than with other cars, and of course a lot of short trips at 40 MPG will still save more gas and mean filling up less often than someone who is driving their Prius long enough each day to average over 50 MPG.

    I think the point that most of you miss in this discussion is that the Prius is one of the few cars that people buy solely because of the mileage (yes, I know some buy it for the low emissions). I doubt anyone who buys a Hummer, or a Navigator, or a Suburban, etc. could care less whether it gets the EPA mileage or not. People who buy a Prius do. Those cars also don't usually sit on the dealers' lots with "60MPG" written in foot-tall letters on the front windshield.
    I think the revised EPA estimates will help sell the Prius once people realize it is still the undisputed mileage champion of new cars, and won't have the stigma of "not getting 60 MPG".

    YOU SAID IT, BROTHER! (or sister)
    I was just going to say this as well. I've bought a few cars in my time and have never even looked at the MPG. Could've cared less. I'm considering buying the Prius mainly for the MPG, so when I see the 60 mpg, that's what attracts me and when I hear it's in reality a lot less it's what cools down the warm feelings.

    People don't care much about MPG when buying other cars. If it says it will do 22 but it only does 18, whatever! But when you buy a Prius your way of thinking changes.
    It's like buying a Ferrari vs. Hyundai. When you buy the Hyundai, you don't look for what's the 0-60. If it says its 0-60 is in 15 seconds, but in fact it's 20, who cares!
    But when you buy a Ferrari, that's one of the main things you look for and if they put with giant letters: 0-60 in 4 seconds, but you find out it's done in 6, then that's a major problem for you.

    So like the person above me said. The Prius is different, it's purchased for different reasons than other cars, so a more realistic MPG advertised would make a lot more people a lot less disappointed.

    All I'm saying is, don't HYPE it! Say its average is about 45 mpg and I'll be happy. But don't advertise it it's 60 and when I go home I find out it's a lot less. Less hype=less expectations=more satisfaction! And vice-versa.

    The new EPA rating is 46 MPG combined which is easy to get with conservative driving habits. I'd say it would be nearly impossible to get 30 MPG. The lowest I ever got (in cold weather) was 42 MPG. Half of my tanks have been at 55 MPG when trying hard for mileage.

    The thing about worrying about the discrepancy and adverse weather conditions affecting mileage is that the same is true of all vehicles. You're still going to get about twice the mileage of a normal car in similar conditions and triple the mileage of some SUV's/trucks.

    Oh and you know that the sticker I was reading on the car actually said it could do up to 70 mpg??? COME ON! This is pure unrealisitc HYPE and should not be there.

    ON A MORE POSITIVE NOTE THOUGH, A COMPANY IN CALIFORNIA I THINK IS MAKING A DEVICE WHICH INSTALLS IN UNDER TWO HOURS WHICH ALLOWS YOU TO PLUG IN YOUR PRIUS AND GET AN EXTRA 50 MILES FOR JUST 75 cents! IT'LL BE AVAILABLE NEXT YEAR. It'll make any Prius "pluggable." If you only take short trips you could get over 500 mpg! Yes, that's five hundred miles per gallon!

    uh... 75 cents in California buys you about 6 kWh of electrical energy. I do not have hard numbers on energy usage, but the Wikipedia article on "battery electric vehicle" suggests that you get 5 miles a kWh, which means 30 miles. And then I don't think I've *ever* seen the battery last that long.

    Try moving to some place that's hilly that gets lots of snow in the winter. You'll see 35 MPG in the winter months.

    Stev0, I'm presuming you live in such conditions? If so, what's the lowest MPG reading you've experienced, and can you further describe just how hilly and snowy the place you live is?

    I believe you and everything, I'm just curious to see how low the mileage can possibly get and what conditions the car was under when acheiving the low.

    Yeah but you plug it in at night when it's a lot cheaper.

    Anyway, i hope I'm not agitating anyone, I'm just trying to find out the "truth" about MPG and all that good stuff. A lot of conflicting info out there!

    And again, I agree that gas economy hugely depends on driving style. In a manual you can double the EPA estimate easily if you know what to do. So yeah, all this you people are saying makes sense. Thanks.
