    I know that Toyota got in trouble for exaggerating the size of the Rav4 Hybrid gas tank. I'm wondering if they got away with that on the e-AWD? I've always filled it up 15 miles after I got a low fuel warning but I never put 8.1 gallons in my tank. If I do a internet search I'm supposed to have 11.

    Just Curious.

    Note that the AWD-e has a smaller size tank than the regular Prius. I believe the 11 gal you’re quoting is the regular Gen 4 size.

    Also, there’s around 10 litres (2.5 gal) of buffer after the low fuel light comes on.

    I always treat my 2021 AWDe as having 10 gallons of usable gas. That is one gallon less than my earlier Prii and leaves a small safety buffer as the fill is inconsistent.

    Yep, my wife's 2017 Prius 2 has an 11.0 gallon tank and my 2021 Prius AWD has a 10.6 gallon tank. I wouldn't know how much is left after the low fuel light comes on....usually get filled up between 1/4 and 1/2.

    Thanks. It may be Google misinformation - lol. I searched "Toyota Prius 2020 e-AWD gas tank size".

    I haven't got a gas tank yet to test my real tank size.

    My 2004 and 2016 Prii had 11.9 gallon tanks.

    The buffer is at least 2 gallons after "empty"

    When my display hits "----" til empty (no numbers), it takes about 8.5 gallons to fill up. I drove another maybe 20 miles AFTER the blank reading and when I filled up, it was about 9 gallons. This was the most I've ever been able to fill up in my AWD model. Screenshot_20220125_111529.jpeg

    You beat me to it. :LOL:

    Amazing what you can learn from a quick peek in the owner's manual. Especially using search on a pdf version.

    Do remember that advertised fuel capacities are almost never from the low fuel warning point. Instead, they are from the "engine sputtered to a stop and left you stranded on the roadside" level, allowing them to claim a larger number. Because fuel stations can be sparse in some areas, and fuel consumption is much more highly variable (depending on conditions) than most drivers realize, and there is some gauging variability, there really needs to be a significant safety margin. Drivers should be given enough advance notice to make a reasonable choice between continuing forward to the next station, or backtracking to the last one, without getting stranded.

    Here is one where a daydreaming driver, not paying attention until getting surprised by a low fuel warning, may need to turn back:

    These cars would be awesome (for the USA) if they had 15 or 16 gallon fuel tanks.

    Topping off is a really bad thing to do, but I don't see any indication of topping off.

    Hang on!! I think I got it. Not the gas tank ... the OTHER tank. :ROFLMAO::ROFLMAO::ROFLMAO:

    On the long trips I manage my coffee carefully. First, it will be 3/4 decaf and 1/4 caffeinated. Second, I drink it if I need it, but not if I don't. It's cold most of the trip.

    I will have something like a smaller hard salami (protein and fat) to eat from, and only take one bite of it per hour or so. Car driving isn't burning calories, and carbs make one sleepy.
