Gen 5 Prius (possible in 2021) will we possibly see 60mpg?

    Even the most pro-ev projections don't have BEV out selling gasoline cars until the mid-2030s. If nothing else, Toyota will continue to develop at least another generation of gasoline engine.

    That said, I think the pure hybrid Prius has served its purpose now that EU and Japanese Toyotas are pretty much all available as a hybrid and even many US models can be had as a hybrid very affordably. The next Prius should be something new, a PHEV or FC-range-extended EV or something. Perhaps dual-fuel (biodiesel+gasoline) compression ignition engine. There are a great many possibilities.

    I'm already getting over 60 usmpg with my '19 awd-e; the tenth tank averaged 3.8L/100kms (61mpg) by the spreadsheet, 3.6/100 by the dash.
    I look forward to seeing what Gen5 has to offer :)

    WOW, that's good. Do you hypermile or similar to get that figure?

    So that's with the NiMH Battery which I think the eAWD has got? Does that mean you didn't have much of a hit with cold-weather?

    As far as I've read, the awd-e has the nimh battery.
    I've looked up videos on how to drive a prius for best mileage, and I try to do that, but I don't honestly know what hypermiling is.
    We've not had cold weather since I got it, and I know that's going to lessen fuel economy.

    Actually, I lied.
    Thinking about it, the first month I had the awdP there was light ice on the windshield most mornings, and my drive to work was just a bit above freezing.

    I was thinking the next Prius would have an BEV version. A Plugin Prime version and a bottom of the barrel Prius with the current technology. I can't really see the point in not offering a fully electric version of the Prius on the 5th generation. As has said before. They have milked the current hybrid technology for what it's worth. Look at the new Corolla Hybrid. Very close to Prius fuel economy.

    Don't forget that TOYOTA isn't concerned just for USA - (though that is a considerable market), but the world scene, including the home market. I'm sure TOYOTA will come out with a BEV when they're good and ready - they can't even make enough Hybrids - RAV4 18 week supply delay, Camry 25 week. Why bother with a BEV - particularly in the vast majority of countries where Electric Power either is quite dirty, or doesn't exist at all. A straight hybrid is far better than a BEV in those situations.

    And - if they were to try to shoe-horn a full BEV Battery Pack into a PRIUS, it would add considerably to the weight, and would need a full re-design to just fit it in.

    Actually - Corolla is quite a long way worse than PRIUS:

    I'd welcome more of the same.

    On the one hand, they do appear to be chasing diminishing returns for MPG. On the other hand, they're still making very practical & reliable cars priced in the 20s. (USA kilobucks)

    Can't do that with BEV technology yet. Toyota can ride the hybrid train another decade at least.

    Though I do wonder... time to drop down to a 6-gallon (22L) fuel tank?

    I wouldn't mind if they'd dial down the 80s/90s fantastic plastic style cues and move all the eco energy display stuff into a phone app. That way the hypermilers can still get all their data (and share/export it!) without complicating the dashboard itself.

    I was thinking the same thing. They just went to their new more or less universal architecture. A full on BEV would require a total departure. It's not impossible, but it's a big expense.

    Having lived in one of those countries, I can concur. Also, at about 50 cents/kWh, it would be pretty expensive even if the voltage sags, spikes, hash, and blips didn't destroy the charger. But I wouldn't even want a regular hybrid there because anyone who could afford the schooling to maintain it properly would be in an office, not a garage.

    I was reading recently that in Mongolia, about half of the cars on the road are PRIUS - all 2nd hand imports from Japan after they get to be 3yrs old and either need to pass an extensive testing - but most Japanese just buy a new car - and the used cars go around the world.

    GOOGLE searches show that between 1 million and 1.4 million used cars are exported from Japan, but I couldn't see how many PRIUS - but there have been PriusChat members who have bought 2nd hand ones around the world ex Japan. PRIUS has been one of the best selling cars in Japan for many years, as has PRIUS c.

    Yeah, I've read about that. But in the nine years I lived in Honduras, I never saw a single hybrid of any kind.

    I would have bought the Prime if it had an awd option. I get that the bigger battery takes up the space of the rear part of the awd, but that would be nice for Gen5.

    that would be fairly remarkable as a hybrid non-plug option. My guess and hope (preference) would be for them to focus more effort on the Prius Prime to potentially offer more ev only closer to what the Chevy Volt had/has. Maybe more.

    Oddly enough, the Corolla hybrid sedan here has nearly identical mileage to the Prius. Your Corolla hatchback is rated close to what our Prius is rated at.

    Not sure if this link drills-down to the search result, but it would be close:


    Fuel consumption ratings search tool


    And a screen-grab of the search result:

    upload_2019-6-4_17-31-40.png

    And I really don't understand their math, for the "Comb(ined)", maybe rounding errors at play? Anyway, VERY close. And the cost per year variation makes no sense??

    That's really odd - the difference between PRIUS and COROLLA Australia that I posted above - shows PRIUS is only 83% as expensive in fuel - yours shows that PRIUS is only 77% as expensive in fuel. We have NiMH in both. Which can't equal similar l/100.

    Someone has made a huge error in one or the other.

    Unless they're using the new Euro measurement WLTP? for one, and the old measurement for the other. But the maths don't equate.

    But TOYOTA EUROPE says all their figures are WLTP:

    The other thing I see is that journalists have got much better economy from the PRIUS. CarsGuide tested both of them recently and used 4.3l/100 with PRIUS, 5.6l/100 with Corolla Hybrid.

    Exactly the same as the Canadian $$ difference - PRIUS using 77% of the fuel a Corolla did.
