    Great feeling isn't?

    Fun to keep track of things on Fuelly. Like the life time stats it gives me in my Prius.

    unless you fill up at the same exact pump twice in a row... variations of when the pump shuts-off can have an affect on your calculated tank average.

    from witnessing a small spike in my mileage, and then not doing so great on the very next tank... you learn that sometimes the pump shuts off earlier than others.. which was the case for me.

    tracking it on fuelly and looking at the calcuations from the car itself... over the course of over 5200 miles... the deviation so far was easily under a 1.0mpg difference between the two numbers for me.

    clearly displaying that the car's calcuations are A LOT more accurate than most people think.

    I did some of those xc trips back in the late 1990s. Boston to Texas (round-trip).
    My best mileage (34ish mpg@70ish mph) was in the old 1991 Plymouth Laser RS. (2L 5sp mt)
    That thing was ahead of it's time. :) A good friend of mine is still driving it to work, down in NJ..

    Anyways, when you hit a certain age, you start taking those kind of trips off your bucket list.
    But, now that we are going to be getting this neat little Red C2,
    maybe I'll reconsider another 2k trip back home.?. :cool:

    Here is my best one that I have a picture of. I have got it up to 75MPG for the same route once but, I don’t have a picture of it.

    Aside from the half mile of 99.9MPG when I've just left the gas station going downhill ;) ... My best was 83MPG on the way to the grocery store. [​IMG]

    The best mpg for an entire tank was 61.something. That took some work, but I don't care to do that all the time.

    Short trips don't matter. I got 99.9mpg on the way home from the grocery store one day. Big deal...short trip.

    I noticed that the trip home from the nearest Shell station (0.5 mi) can all be done without getting out of EV mode .. start gently, accelerating to 25 mph on the 1/4 mile highway stretch; The remainder of the route in the neighborhood, including a small uphill climb, where I have to drop to 15 mph to stay in EV, then a left turn and backing up into the driveway.

    As per the ECO Monitor, correct? I noticed that the monitor always shows 6% better MPG than the real figure (gallons of fuel added to the tank, divided by the odometer reading), but I don't know if all of them do, or it's only mine.

    Ha! Lately, I have always been getting gas from the very same pump without rationalizing it .. doing the right thing intuitively, I guess?

    QUOTE="unigeezer, post: 2152725, member: 42793"]Looks like this non-prius set the record for highest mpg.

    2013 Volkswagen Passat TDI Sets Guinness Fuel Economy Record | Edmunds.com[/QUOTE]

    "...set the record..." refers only to the record for travelling through all the contiguous states. There are plenty of better MPG figures for Prius at pretty good distances. I have averaged 114 MPG calculated at the pump for 501 miles and over 86 MPG for a tank over 700 miles.

    I was ignorant of a way, at the time, to calculate an internally consistent figure using the Prius c ECO settings screen for MPGs above 99.9 . Now I am not.

    My 501 mile trip shows the 99.9 max recorded by the trip meter. It is what I claim as the MPG figure, but it was well over 100 MPG.

    Here is a little Youtube video showing how using the screen allows me to calculate a short twenty-something mile trip at 119 MPG:



    Watch it on youtube to read the accompanying information, if you are interested.

    What I was basically inferring is that you can greatly increase mpg on pretty much any car with well executed "hypermiling" techniques.

    Excuse me. It sounded more like a statement of fact about setting a very specific 'highest mpg record' than an inference.

    Check out the VW xl1 for a production (albeit very limited) car that gets over 200 mpg. We won't be seeing it here in the U.S.. After VW group got static from the 'greenies' for the temerity to produce the Veyron, the xl1 was the answer (in addition to the finger.) :)

    Doesn't every car manual have a section, telling the owner how to attain better MPG? The same common sense principles: Do not drive with the roof rack on and/or with weighty items if you don't need to. Avoid sudden acceleration and the "gas-brake" driving style. Keep the tires properly inflated and the wheels in good alignment. Purchase gasoline from reputable retailers. Only turn the AC on when the fan is not coping. Do not drive with windows open at high speed, and especially with open windows and the AC on. Keep the engine RPM in the max torque range. Above 55-60 mph the air drag increases "exponentially" ..
