    I have a base model 2017 Prius with the 15" wheels. The car is rated for 4.2l/100km (56MPG) officially. It is running on the Ecopias for about half the year and 15"steelies with X-Ice during the colder months. No modifications other than removing the plastic wheel caps in favor of center caps for the alloys because they look so much better this way.

    My car has achieved 4.1/100km (57MPG) over 74,000km (46,000 miles) which I am very happy with considering the climate I live in.

    What overall mileage has your car achieved in the real world?

    Yeah I'd say mine was around the same, give or take a couple of MPG.

    That IS stellar, I'm jealous. :cautious:

    Pretty much starting on a new tank with trip meter reset, we did about 60 km yesterday, and trying hard (3rd gen with 15" X-Ice on Corolla steel rims), I knocked it down to 4.9~4.8, displayed. Which'll be something like 5.3~5.2 calculated. :cry:

    My fuelly badge was at 4.9 for a while, but back up to 5.0 now. New 17" Primacy MXM4 didn't help.

    Is your's calculated?

    That is what the car displays by the odometer reading. I've done some calculations and it seems relatively accurate. Regardless, those fuel bills are always a good laugh. We have a 2020 Corolla and that thing feels like a gas guzzler in comparison.

    I was thinking about getting some 17" wheels and some softer tires for better grip in the corners and shorter braking distances but I just can't justify it because I'll lose my score. Hooked on the fuel economy game too much. Plus, I like money. Lol

    My average is 65.88 mpg. Lowest is 57.51. Highest is 70.91.

    All since ownership.

    Must be pretty warm where you live to have such a high average. I believe it though because my summer numbers are similar. Winter is challenging and I'd be lucky to get 62 mpg round trip if I really try for it and go for long enough to get the engine/battery to proper operating temperature. Short trips really kill fuel economy in colder climates for sure.

    I believe it has as much to do with driving as well - taking other things into a/c (cold etc). If I'm in the mood and the traffic is light and I'm not annoying other drivers - it's easy to get another 10% improvement with a light right foot. Some people get better economy than others in the same car.

    Loan your car to a teenager to check that out - they'll manage 20% worse.

    My winter numbers have gone up substantially. My guess is that the Prius just isn't geared around the 90 to 95 degree days of summer. Now that it's cooler (in the 60's and mid 70's) I'm seeing much more satisfactory fuel economy.

    4.1L/100km in the summer but winter is 4.5-4.7L/100km. Both numbers are urban/city only, no highway driving.

    That is pretty much standard for a Gen 4. I am sure some do better.
    Time to upgrade your garage queen... ;)

    By my wife's definition I an NOT a hybrid driver. Here in Virginia I think lifetime he around 58 mpg, with probably over half highway driving. In the winter I am usually pretty successful in keeping trip mpg over 55. Summer I aim for over 60.

    For mpg bragging rights maybe, but going through roughly 18 litres a month, the monetary difference would be peanuts. Too, I’m NOT enamoured of 4th gen styling, inside or out. Apologies to all present. :whistle:

    My fuel usage has probably been in that range for the last 9 months too. 4th Hen styling is better that’s the Prime though. Ugly black grille on the front and ugly Honda tail lights on the back.

    no apologies to the design team.

    We went to the airport last night in the wife's '17 trim 2 (not my Prime), 21 miles to the south of us. Two of us in the car. Wind was 15 mph out of the south. Speeds were mostly 50-55 mph.

    Going down, we got about 57 mpg. Coming home, we got just under 68 mpg and it rained half of the way home with three people, one suitcase and a carryon bag.

    Heck, I'm happy with 43 to 47 MPG when I see it. Still averaging 42 MPG though.

    Just picked up my new Prius L Eco Last night and drove it home 12 miles and then to work where I deliver pizzas and back. Put about 70 miles on the car since I reset the trip meter when I left the dealer and got 57 mpg so far. Mine is a 2021 Prius L Eco. Temps are cold (by SoCal Standards) during and on my way home from work, temps were in the 40's.

    4 years ago, I rented a 2016 Prius (NiMh pack) and got 59.6 on a 1400 mile trip from Orlando to NC and all around with a family of 4 and 100 lbs of cargo. Ever since then I have wanted a regular Prius. About 5-6 years ago we had a 2015 Prius C for maybe a couple years max. Cute car, but it short/blunt shape and Prius II powertrain was underwhelming. I really tried and it would be 52-53mpg lifetime, but due to the higher wind resistance (drag) the car really dropped off in MPG at freeway speeds of 70+, unlike the current Prius. =)

    Currently halfway through a tank (3rd gen Touring), on Michelin X-Ice 15” (on steel rims), the trip meter is showing 4.3 liter/100 km, which likely will be 4.6 calculated, and the latter translates to 51 mpg US. Surprisingly good for us, attribute it to mostly longer drives. :)
