    Wow! Excellent work. Thanks for the report, too.

    Is it fair to say he drives mostly slower speed routes?

    Do these results come with mostly steady state cruising, or more P&G?

    Congratulations! He's a real Shogun of the hypermilers :). On the other hand, if he uses a plug-in (as was mentioned in his video profile), it puts his results into a perspective. MPG is totally unsuitable metrics for plug-in hybrids, because the car is taking additional energy from somewhere else.

    Thank you!
    His basic technique is P&G and the speed limit on his commute is 50km/h (31mph) or 60km/h (37mph).
    Also, please refer to following about his driving style.
    http://priuschat.com/forums/gen-ii-...-1300-miles-2119km-per-tank-2.html#post100973

    His plug-in is for the engine block heater. :(
    Anyway, you're correct his Prius receives the external energy.

    Oh, it's just a block heater? Well, that puts his results into an entirely different perspective once again :). Kongurachure-shonzu, Shogun-san! :clap2:

    wow!! His lifetime average is the Japanese 1-15 cycle's mileage estimate!!! It's 35.5km/L for the Gen 2 (nearly 80mpg)

    Congrats Shogun-san!

    Occasionally someone will start posting arguing that brisk acceleration is the wrong way and that a slow acceleration is better for mileage. I certainly hope that we can all learn from the super-hypermiler who practices exclusive brisk-acceleration.
    And I'm, in no way, claiming to be perfect. I often have to remind myself to pursue brisk acceleration.

    Thanks, Ken

    Thank you all for your warm words!
    Interesting thing is his mileage improved year by year.
    This year, his average FE is now 39.94km/L (94 mpg: 2.5L/100km). :cheer2:

    I believe the HV battery is still strong after 113k miles.

    Great record! I particularly like the yearly improvement and the longevity of the HV battery. Thank you!

    Could it be that the tyres are wearing in? I know my mileage improved yearly until I got my 3.9L/100km tank in the summer of 2007.

    It's really hard to do 60-40 where I am now because this city is a LOT more spread out and have higher speed limits (60km/h and 70km/h limits on city streets). Hopefully I can go home soon and try to get a 3.7L/100km tank.


    That's good to hear. P&G doesn't have any negative effect on the HV battery. 113k miles.. that's 190,000km?

    Great video and a great achievement. I'd hate to get stuck behind all those hyper-milers when I'm in a hurry though.

    Our good friend, Ken1784, is seen briefly at minutes 1:58 in the video. One of our most respected tool makers, his brilliant work has made many high mileage efforts possible.

    Are you imagine he is still using the first set of tyres for the 113k miles? :)
    I don't think so.
    I think I wrote it's 181,855.5 km on the top of this thread.

    He's all over youtube as well ... demonstrating high mileage techniques with the japanese hypermilers. I've spotted untold numbers of us PC'ers there. In fact here's one vid with FOUR of us crazy PC'ers ... two of 'em are mods.
    :rolleyes:

    being all famous . . .
