    Hey all of your Prius owners, does this car really get close to 50MPG during regular everyday driving conditions or is this kind of mileage achieved by hypermiling?

    What is the typical realistic mileage for both city and highway use separately, not combined?

    We have a 2005 Prius that we drive always in mixed highway and city as we live between 15 and 20 miles to the cities. During warm weather (April-October) it has averaged between 54 and 58mpg. We are not doing anything special to get that average. In the winter it drops down to 47 to 49mpg. We have Michelin X tires on our Prius. They are much better than the Goodyears that came on it. They have 40F38R PSI.

    My lifetime is 4.9L/100km or about 48mpg.

    50mpg is doable in the summer without thinking much but why would you? Summer is the time to get 55mpg and more.

    It's says 51.5 MPG on my Multi-Display right now, doing JUST DRIVE IT.

    Maintaining that throughout the summer is pretty realistic... without the carrying the bikes or kayaks, drag down MPG... so does winter.

    I'd be disappointed if I only got 50mpg. I don't really hyper mile, in fact I like to be first away from every set of light but otherwise I drive pretty normally but I am careful not to need to brake hard but that is just good driving practise.

    I get about 55mpg on average around town commuting.

    Our lifetime average is about 52 mpg. If I didn't pay any attention, it would likely be near 50 mpg. I pay attention to what I'm doing, but I don't do anything near what I'd call "hyper miling." I just drive the thing reasonably.

    This is the 2010 Prius subforum, so I don't know how many people here can talk authoritatively about that car.

    I'd suspect since the EPA testing puts it at 50 mpg, and the previous model at 46 (which most people seem to beat without too much effort), then I'd guess the 2010 should do 50 mpg easy.

    Our 2006 gets mileage in the high 50s during the summer without any funny driving. If I only get 50 mpg I have a problem.

    Contrary to the EPA and many Prius owners, I get around 40 - 42 MPG around town, and better than 50 MPG on longer, freeway speed runs. I think that is because I don't commute to the office anymore, but around town do very short, 4 - 6 mile trips, so the car never really gets to a stable, cruise temperature situation at steady speeds. My Prius is a 2008, package 2 model with the original tires pumped to 42F/40R PSI. My lifetime average over 19 months since delivery is 44.2 MPG, covering 9900 miles.
    That is lower mileage than the average Prius owner I would imagine, since I am retired and drive far less than the average here in SoCal. So your MPG results depend greatly on your driving profile and variations in it.

    As it would with any other motor vehicle that has an internal combustion engine.

    We live in a valley and have to climb over and down to the nearest town. Our 14 mile one way trips average between 47 and 50 mpg. On longer trips, with the cruise control set at 60 and doing nothing really special we get 52 mpg. We've had our Prius for three weeks and it only has 700 miles on it so it is still breaking in. Tires are the Integreties inflated to 42 front 40 back

    I took four years of user reported data, 2005,06,07,08, from the EPA web site and got the following distribution.

    Now I drive a 2003 Prius, the previous generation, and I don't 'hypermile.' I drive efficiently by using an optimum route to and from work; radiator block in the winter; and the highest quality gas. I also keep my highway speed in the 65 mph range and try to climb hills at 55 mph. I run my tires at maximum psi; two engine oil changes per year and wheel alignment check and correct; one throttle plate cleaning and air filter change per year, and; transaxle oil every two years.

    I get the same profile. Around town, I get mid to low 40 MPG, but on highway driving more like 50 to 53 MPG, as measured by the MFD. I have reduced the highway speed to 60 mph, and I do see a 5 to 10 % increase in MPG, as displayed by the MFD.

    Scott, the government sets the standards and does the testing for mpg for all US autos. They do this so that you can compare apples to apples in terms of fuel economy. Of course, there is no hypermiling allowed in these tests.

    To answer your question, I do not hypermile, and I average around 48 mpg in the winter (live in PA), and around 55 mpg in the summer.

    The last two tanks, I got 4.79 and 4.77 L/100km, which comes out to 59.01 and 59.20 miles per imperial gallon, 49.1 and 49.3 miles per US gallon. I'm in the 'just drive it' mould, though I've been adapting my driving style a bit to try for more efficient acceleration, and gliding down to upcoming stops.

    The car is currently showing 60.5mpg which is optimistic, based on the last three tanks (the first of the three was 54.02mpg by my calculation). Full life, my average is ~5.1L/100km - 55.5mpg (I) - 46.2mpg (US). Worst tank was 49mpg(I) in January, best was 63.86mpg(I) in July last year.

    I logged around 51 MPG driving 90% highway in 37 degree weather in the 2010. In my 2006, my average would have been around 47.

    The 2010 is going to hit some awesome numbers.

    in my 2006 my So has been the primary driver since i got my Zenn in Nov 2007 and she does not hypermile. so most of the stats posted are hers. granted the average has dropped a bit, but i think her overall average is still above 50 mpg and 80% of the driving is in town where the mileage can really do a hit or miss.

    on the freeway, assuming no congestion, you only need to keep it below 65 mph to average 50 mpg

    all i can say is before the EPA changed its calculation method, the Pri was rated at 55 mpg overall. i got that. my SO gets just below that and the 2010 is almost 10% more efficient... so you work the numbers, see what you get.
