Japanese Mileage Maniacs

WY writes "Bloomberg reports on the quirky world of Japanese hybrid car hackers: 'Toyota Motor Corp. says its Prius gasoline-electric hybrid car gets about 55 miles to the gallon, making it one of the most fuel-efficient cars on the road. That's not good enough for Takashi Toya.' He managed to reach as high as 115 MPG. He is one of about 100 nenpimania, Japanese for mileage maniacs."

  1. How "real" is their driving? by xmas2003 · · Score: 3, Insightful
    The article is a bit light on details, but my guess is a significant factor is they are driving on fairly flat terrain, they really minimize accelerations, and probably stay below typical highway speeds since air drag becomes significant. I.e. I'd like to see 'em get 100+ MPG driving over some Colorado mountain passes. Article also doesn't talk about this, but I bet for long trips, the savings in gas that is offset by the extended driving times ends up valueing their time at a pretty darn low $$$/hour.

    Sure, I'm all for more fuel efficient cars and less fossil fuel burning, but there is a tradeoff.

      Japan is pretty mountainous -- obviously not as high as the rockies but lots of up, down, and around.

      Well, obviously I'm not trying to promote a variation of playing chicken. Sure, in situations as you describe one has to break or change to a lower gear to keep the speed of the car in check. The good thing about a car capable of charging its batteries when breaking is, however, that break energy goes to the batteries and can be re-used fairly efficiently, whereas in regular petrol cars you're heating the air and go for early replacement of the brake pads. My main point is merely that the way one drives is of effect on how much one spends on gas, and the second point is that while some aspects of the energy-saving driving style lowers the average speed, others increase the average speed.

  2. Why only 55? by Brad1138 · · Score: 4, Insightful

    It is good to see people getting "real" good mileage. The Prius gets 55 MPG, the Geo metro and Honda civic in the late 80's and early 90 got mid 50's. I heard some GM exec on the radio yesterday talking about the new 50 MPG small cars they were bringing to market, what, "used Honda's"? If a regular engine can get 50+ MPG it shouldn't be hard for a Hybrid to get 70 or 80+, if not 100+.

      Good point, our regular turbodiesel Skoda (a European car) gets 70-80 mpg even if you not trying. It's always fun comparing American and European cars. Other point is - they all have one person in them anyway, so theoretically, they should all do like 200 mpg, right? It seems so wasteful to be dragging around two tons of metal to transport one person.

  3. Mileage mania? by RyanFenton · · Score: 2, Insightful

    Mileage mania? What does that make stretch Hummer/fuel injected racecar owners? Sufferers of Mileage Dementia/Depression?

    My favorite motorcar extremists lately are the guys strapping together thousands of dollars worth of batteries to make ultra-high performance vehicles that still get 40 mpg. Sure, they have to go light and limited to 100 miles range per charge, but they end up with a true racecar that makes no sound except the burning of the wheels. That's just damn cool.

    Mileage itself is a bit of a red herring though - there's always going to be a need for vehicles with 'horrid' milage, and 'wasting' that fuel to move earth, or just push a lot of metal - it really isn't an inherent problem to 'waste' fuel on big cars. The only real concern is the effect using that fuel in a fuel cycle. If going through that cycle returns the earth to a carbon-rich atmosphere, that's not a good thing. If the cycle doesn't involve such troublesome consequences though, then as long as the fuel is worth it's other negative effects (like on your wallet), then I don't see how it's a problem.

    We just need better fuels and energy source paths. The market's having a hard time finding a good set of somethings for now - but the dynamics look to be changing, thanks in large part to a lot of nations making some rather interesting long-term investments in fuel research. If you get the right fuel, then I'd much rather have a fuel-inneficient car that theoretically retails for $12,000 after mass manufacture, than a maximized fuel efficient car that retails for $50,000. We need fuels we can waste, so we can consider fuel efficiency completely in terms of direct cost rather than indirect environmental impact as a society.

    I look forward to being able to waste a lot of new kinds of fuel in the future. Here's hoping they come up with one that smells like rich coffee ice cream!

    I'd rather get my 30mpg and drive a comfortable, good looking car with enough power to boost around a triple-trailer semi truck without spending much time in his blindspot than get 116mpg and have to drive what looks like a douche electric shaver.

    Huh? I never do this, but +5 informative?

    If you think US roads are poorly designed, please come to Japan and spend some time driving. These people in the article must spend all their time on farm roads during off hours. Japanese roads are by for the worst anywhere for cars. (and I have driven on four continents.) Nothing but stoplights, traffic and people. The stoplights are never synchronized and going anywhere in Japan by car painful by US standards. Why do you think they developed the hybrids in the first place? --- because of all the stop and go driving.

    two) How exactly does sprawl help protect against nuclear terrorism? Maybe you mean low density sprawl, but only killing 10,000 people per square kilometer is hardly protection! especially since the terrorist would simply bomb the high density bits.

    three) If low density development is encouraged, mass transit and bicycles become impractical, highways become necessary for most travel, and you end up with LA. have you ever driven in LA?

  6. Re:US fuel efficiency figures seem incredibly poor by Paulrothrock · · Score: 1, Insightful

    US auto manufacturers have convinced Americans that they need 4,000 pounds of steel wrapped around them to feel "safe" on the roads, and that 25mpg is the price you pay for "safety." What they can't bring themselves to say is that the best safety gear is between your ears, but that's just because most Americans don't seem to have come with that as standard equipment.

    (I'm an American, so I can speak from experience.)
