Update: 100k miles on my new 2020 Prius

I was able to achieve 80 MPG tanks with EXTREME HYPERMILING along familiar and eco friendly slow driving routes. A couple 800 mile tanks to go along with it. But, it was hard work and annoying to anyone that happened to be behind me. No heating. No air conditioning. So, I know it’s doable - but only for a dedicated fee.

 

The car makers are forbidden to advertise any MPG figures other than the official EPA ratings, which are derived from standardized tests. These 3 guys are not following the profiles of these standardized tests.

Some car makers, e.g. Ford and Kia and Hyundai, got caught cheating or over-stretching rules on their tests on certain models. The EPA re-tested themselves, gave those models new lower MPG ratings, and forced the makers to provide a certain amount of refunds or credits to customers for the cost of the fuel difference. Kia and Hyundai also had to pay a $100 million civil penalty.

Note also that the official EPA figures are sharply discounted from the actual dynomometer test results, to more closely approximate common ordinary driving conditions and typical (inefficient) driver habits. These 3 guys above have gone to great lengths to wring those inefficient habits out of their own driving styles, and to drive more efficient profiles than EPA / CAFE specify.

You have a 2019. For what it's worth, the regular 2019 Prius scored 76.6865 mpg, and a Prius ECO scored 83.5598 mpg, on the Unadjusted City tests, before all the discounts and empirical fudge factors were rolled in to create the official figures that are put on the Monroney label and in advertising. Full scoring, including the raw unadjusted figures, is available in the annual Datafiles on this page.

 

Amazing if true.

Can such a dashboard readout of the Average be created for a shorter driving distance, and still show total miles (100k in this case) on the odometer?

 

If a Gen2, in the hands of a skilled hypermiler commuting in very favorable conditions, can get 118 MPG over a full tank (a larger Japanese tank with no bladder), then it shouldn't be a surprise that a Gen4 ECO can achieve 80+ MPG over an extended distance. We just need to find someone with the right combination of skill, patience, and favorable driving conditions. That convergence is less common here in the U.S. than in Japan, but it does happen.

Here are some of my old posts collecting links to some other extreme MPG threads:

Mileage?!!! | PriusChat

There are also some U.S.-based 100 MPG challenge threads laying around here somewhere, from the Gen2 and Gen3 days. A Gen4 ECO should make it much easier. Especially in the hands of any friend of 'Uncle Wayne'.

 

Trip meter A can do that. So can trip meter B. Or just use the one that resets itself every time you start the car. Any of those will show the average since the last time they got reset while leaving the odometer average alone.

 

Well, I keep coming back to the heating / air thing. If this can truly use 30+ % more fuel, then maybe I could get 75mpg without taking "any other" of the hyper mileage measures being talked about here. Because, as I said, I use heating / air, more than 95% of the time, and in fact, I do a LOT of just sitting parked with my heating / air cranked > read: using plenty of energy, and traveling "0" miles. So maybe with this said, my 52.6 is pretty fantastic, huh ? Still does 300% better than my Ford F150 lol

 

Yup. That stuff clobbers your mpg & m/kWh. Especially if it's unusually hot or cold. From what I hear from relatives in Sacramento, it does sometimes get a little toasty there. LOL!

 

Exactly.

Prius folks confirmation bias is the only explanation for the tone of this thread. That, and everyone’s kind nature here.

While 80 MPG may be possible, not driving an average of 250 miles a day, 7 days a week, for 13 months straight.

Good to return for a few quick posts.

 

I LOVE the toasty part 100-105F with super low humidity, and a little shade, a cold drink, and especially a little breeze, is easy peasy I bet people from the deep South would think it was 80F !
Now the cold here is the opposite Our most humid times are in the Winter. So if its 40-50, it feel freaking bone chilling and miserable. I freaking HATE Winter

 

Wow. 100k? And I thought closing in on 17k in my 2020 (got in February) was high. How long is your daily commute?

 

With those numbers, that isn't a commute to a job. Driving is a major component of the job itself.

 

I just checked my MPG after about 129K and boy was I surprised. I do have a lead foot, but this is ridiculous.

 

Looks like someone held the trip meter button too long. I did that a couple months ago myself. Now my Prime's ODO mpg reading is stuck at 199.9. I could kick myself.

 

this could explain why you have to get gas twice a day, however
