    Volt EPA highway estimate is 40 mpg and it's easy to get mid-40's at 55-60 mph. The Ford Energi C-MAX gets a 41 mpg estimate on the highway. The Prius Liftback highway estimate is 48 mpg and the plugin is 49 mpg.

    Very few cars come close to Prius gas mileage.

    As big motorcycles zip aside me while lane splitting, appearing out of nowhere, I note to myself that I am probably getting as good mileage as they are, and having a much more comfortable ride.

    Greg,
    You are getting fantastic gas mileage! Speed is everything and your right foot determines how much you use that gas. The ECO button does nothing to control your gas mileage.

    With the Volt when burning gas you get only 82% of the gas mileage of a PiP.
    But, in exchange for that, you get the first 40 miles for $1.20, (in my area. others pay less, some pay more).

    This results in me never burning gas, unless I head out on them Road Trips !!

    I have to respectfully disagree. The ECO button does nothing if you know how to drive perfectly for best fuel economy, but since I don't always do that, the ECO mode keeps my acceleration very modest, unless I need full power, in which case a foot-to-the-floor gives me that.

    FWIW, I just returned from a 1,700 trip in my Volt.

    ICE gas mileage was 41.5 - 43 at 65 - 70 mph, depending on terrain.

    Very pleasant trip. I charged where I could for in town driving and used Hold mode whenever I was on the highway.

    20 minutes gets me about 120 miles, 30 minutes gets about 170 but then it starts tapering off.
    We had some concerns when approaching the Rockies, simply because it was the first time we had such elevation changes. On the return trip we had no such worries as we were no longer new to it.
    We drove the speed limit the entire trip except the leg between St. George, UT and Las Vegas, Nevada (285 miles) (we took a different route to see Two Guns AZ on the way back)
    Currently driving through SD we are driving 75-80.
    We have used no charging other than superchargers, and our total fuel bill has indeed been zero.

    I don't doubt you have seen some owners driving slower than the speed limit, just as you see owners of other cars driving slowly on occasion.
    It may be they were stretching their range to get somewhere, or that they were new to driving electric, or they were simply slow drivers.
    For myself, I am almost always less than 5mph over the limit, rarely below.
    With car like the Model S, it is rare to see them traveling slower than the speed limit:)

    So far no one has provided more objective evidence about what is the most high tech than miscrms. Don't know how you missed it - please see miscrms's recent posts over the last few pages of this thread. Yes Argonne and Idaho National Laboratories.

    No opinion here because ANL and INL have already answered that question with data.

    No brand loyalty/worship here. I had a diffent car make before Toyota and will possibly again with the next car. Tech is important and a big reason many of us on this site picked the PiP. That said, I'd rather drive a Tesla if money was no object. Right now that's the only other vehicle that could get me where I need to go and use even less gas.

    I believe a typical 100 hp car is chewing up the equivalent of 75 kWh of power just driving down the highway. At least 75% of that is wasted by pushing air, friction and waste heat.

    If cars were all electric, and could be robotically controlled to travel on highways in tight formation, then heat would be reduced, air resistance would be minimized, and safety would be improved. I see a bright future for the Google car.

    It takes about 15-20 kW to go 60 mph steady and about 25 - 30 kW to go 70 mph. Maybe 45 - 55 kW to go 100 mph.

    75 kW is equivalent to 100 hp.

    And as I said: Saving a few pennies on 11 miles of range is not a measure of "the highest technology".

    Yes, the PiP is the most efficient, lightest, and least capable EV car while doing its awesome 11 miles at <62 mph. That is a measurement. It translate to usefulness to those that only need that.

    Yes, as a gas burner it has the highest tech engine out there!

    Are you talking about the Otto Cycle engine, patented 1861, or the Atkinson Cycle engine, patented 1887?

    I believe in the Prius it's called a Pseudo-Atkinson Cycle. It is not anything like the original design.
    It is a modern electronically controlled engine that still uses EGR. It uses the variable valve timing to emulate Atkinson. It runs a high compression ratio but never uses that effectively unless at high altitude. It has a exhaust gas to coolant heat exchanger to get the engine up to normal temp as quickly as possible. Plus a lot of other high tech crap, I'm sure.
    It's a high tech gas burner.

    I still can't understand how a SW load to the Volt's engine couldn't do some of the Atkinson-like process.

    But even more high tech is not turning on that gas burner at all during most normal driving duties. (wink)

    Just curious Bill - how much gas have you personally used in the Volt ? EV% ? MPG ?

    To be fair, that isn't "high tech" as much as it is your preference. If it were, then you could call a bicycle higher tech than a Volt because it never uses any gasoline.

    I can't answer for Bill, however, while we had our Volt we used 80 gallons over ~15,000 miles.

    Maybe that explains my excellent mileage here at 3500-4000 feet ASL.

    forty,
    I am at:
    11.9k elec. miles
    5,175 gas miles.
    70% electric.

    As for MPG,,,, that does not compute.... as I've said before those MPG numbers, such as in your signature, are Bo oh gus...
    When you present those MPG numbers it acts like electricity is free. I don't bother with those numbers.
    70% of the time I'm getting MPG...
    When I am on the highway burning gas on a long road trip, I have measured 37-41 MPG. But that is usually at +5 the speed limit or more! Sometimes this can be 80 mph in parts of OK. And is not taking into account winds.

    I'm not Bill either--I was at 94% EV in my Volt before our vacation the last couple of weeks. Now at about 84% with about 11,500 miles and 11 months on the car.

    Fair enough. My lifetime MPGe though is 139 right now
    Amazing how close we are in electric miles - just hit 12,020 EV, just 1,180 gas though = 90% electric
    diff cars for diff needs
    I have a friend who bought a Volt who'd be better off w a PiP - my daughter def better off with a Volt

    I look at MPGe the same way I look at wind-chill; it's a meaningful number, but you can't compare it in any way to actual MPG.
