    I think Wayne posted a map, just check and see what the limits are on those roads.. he probably would choose a goat path somewhere if the speed limit was 15mph :)

    The limits were between 45 and 65. That's simply too big a range to know much.

    Wayne said 45-65. Believe it. And don't expect him to give you steady-state numbers.
    I would imagine his speed varies with the terrain. Do you really expect to get insane numbers travelling at "typical highway speeds of 60-65" ?

    You're right, getting rabid.

    I'm not sure why this question seems out of line. Wayne was traveling on an interstate highway. Our interstates in the midwest are either 65MPH or 70 MPH, so traveling at 63-65 is not really pushing it. Short of buying a Prius C just to find this out how it would do on the highway, I thought the question was valid. Was Wayne generally driving more of the trip near 45-50 or more of the trip 60-65 mph?

    I think the answer is more that he wasn't doing steady state driving.

    Hi All:

    I am currently in CA on a short event drive so to speak (660 miles today so far) and there is no steady state unless you force it on "name your road here". Do you start at 52 mph, finish at 52 mph everything in between is at 52 mph? If so, you have a perfect 52 mph steady state drive and nobody does. When I say between 45 and 65 mph, it is 45 at the top of any DWL hill and 65 max with full regen coming down any slope to keep my speed legal.

    I hope that helps?

    Hi Herm:

    Just a wee bit faster than the goats :D

    I am currently in the early planning stages for an extended drive of the c and hopefully we will have more information on the speed crossover point where the third generation Prius begins to surpass the c on the interstate. Maybe even a back to back with my mom's own 2010 at various speeds.

    hi wayne, great article! I was wondering for future reviews would it too much to ask for your average speed when posting MPG results? Or do you think that would be a distraction for your site considering if people saw the low average speed people would have less incentive to hypermile?

    the reason why I ask this is I drive a lot of highway (200 miles a week) and although gas is my precious gold, it seems these days time is my precious lithium if I had to put it that way!

    that and I'd be interested what car had the highest average speed + MPG combination

    and these days acceleration + mpg combo stats would be sweet too! For example my 04 prius can increase speed (by a digit a second) whiile having the instantaneous FE at 30 mpg US or better.

    Either or, looks like 500 lbs off the HSD system proved to help FE a lot for the Prius C, just because of demand getting one for a good deal seems like finding a needle in a haystack. Since I could get a 2010 prius fully equipped with low miles for much less!

    Hi Phil:

    For a Preview drive I cannot because I do not have steady state speeds, an optimal route to achieve them on or the time to perform them. At a Preview press launch, if you get 3-hours behind the wheel while sharing with another journalist, you are lucky. In addition, the routes we are provided at a launch are scripted so you have little or no leeway for a good route.

    Fortunately at some of the Toyota launches, they sometimes allow me a few hours late in the afternoon after all the other journalists have called it a day. Afterwards, I can knock out a quick measured fill drive as I did with the Prius hatch, v and the c. I learn more on these non-scripted measured drives than on the scripted routes but if the manufacturers allowed all of us to “do our own thing” first thing in the morning, half the journalists would not have vehicles to drive and the other half would be lost meandering their way around whatever city the launch is being held in. Me included :D

    If you look at our reviews, I usually include a table of 50, 55, 60, 65 and 70 mph steady state speeds with the conditions in which they were achieved.

    When we get a Prius c in for a full week review hopefully sometime this summer, we can get those steady state numbers knocked out.

    Remember the 50% loss in FE by driving to another’s whims cost you both time and $'s at the pump so make your time count.

    I hope that helps and it is great to see you back at CleanMPG!

    aca2983 , I just read that today. But I don't recall seeing any "bare metal".
    Where is it ? What would you prefer it to be covered with ?

    Hi All:

    At last week’s Midwest Automobile Media Associations (MAMA) Spring Rally, the Prius c allowed a decent amount when let loose. A non-calibrated SGe said 127 mpg but leaving with 4 bars and arriving with 3, we’ll give it a solid 110 + mpg.

    Can the c travel on electric power only and if so, how far approximately and is it speed limited?

    Hi Reid:

    It is just like a Prius II with about 2/3 the pack and a few hundred pounds less weight so it has a lengthy EV distance. Maybe 1.5 miles vs. 2 if you are really easy on ht pedal from a full SoC. 45 mph glides seems to be as easy as letting them occur with the EV icon next to the SoC telling you if the ICE is down or not.

    Each iteration of the Prius drivetrain just gets better and better. I was just over at my parents and my mom’s v is showing 51.8 mpg after 191 miles and she’s doing short trips with A/C on all the time.

    Just amazing how efficient the c and the v really are.

    questions from a current NHW20 owner (260,000km wee!) and Hi Wayne thanks for answering my questions from the other reviews/threads :) glad to see cleanmpg is still super strong!

    - If you have to give a % on how much better the NHW20 handles compared to the C can you give an estimate? I'm a sucker for cornering while trying to maintain momentum even though it throws everything in my car from one side to another!

    - Wind noise on the highway? I've driven cars where non hybrid cars were probably 15% quieter than my 2004 prius. Then again its strange even as areo as my car is wind noise is still an issue.

    - So since I'm somewhat happy with the NWH20 performance (45-55 mpg average while maintaining the highest average speed/efficiency ratio) even though I would like JUST a little bit more passing power on the highway. SO with the same engine in the C but 300 lbs less am I going to be a happy customer?

    - Does the prius C still have the annoying stage 1, 2, 3 4a,4b (so stupid!) when it reaches 70 degrees Centigrate it should glide at will and not me having to pass 56km/hr before the engine shuts off via glide. But thank goodness the EV button works for 55km/hr and below however, I notice new HSD systems limit it to 40 km/hr. But what happens if I want to coast from 50 km/hr and I haven't reached stage 4b yet? Is it still a problem with the 2010 priuses as well?

    - Finally ECO mode all the way? Never have a reason to disengage it?

    - i remember there was a good web site displaying all the MPG vs MPH range for all the hybrid cars in the government fleet but cant remember where... curious to see the data.

    - EV Button only works when coolant is above 70 C right? Dissapointed since my NHW20 can do it when coolant reaches 40 C :D

    Nicer looking car than my aging NHW20 at least ;( Thanks Wayne! Keep up the great work!

    Hi Phil:
    Since the Prius-II is not a great handler, you will not have a problem with a c. Both have some body roll and I can almost bet they will hold within .02 - .04 G’s of one another at the limit.
    It has been to long since I was in one to give you a definitive answer on that. Go to a local dealer and take one out.
    The c is not as lively as the –II but it is more than adequate.
    Beginning with the third gen, the warm-up stages have been relaxed with what is and is not available. While I cannot discern the exact changes, the temp restrictions are there but a lot more can be done prior to the previous and strict stages.

    EV works with SoC and little Acc use, Stage 4 can be induced without an idle check or 15 minutes on the highway and even then you may still have failed glide with the -II. I have not seen that in the c or v, ever! I have long ago forgotten the exact detail that you live with on a daily basis thank goodness. In any case, from the 10 Prius, CT, v and now c, the warm up restrictions have been eased thanks in part to the warm up HX’er and easier SW calibration from Toyota’s HSD magicians.
    I never disengage it but others do…

    IHTHs

    Just bought a C II yesterday. Still learning but already up to 68mg over the first 170 miles of mixed highway / slowway driving. So far, so good.

    Congratulations. That's pretty good! I get about 60mpg on my tanks and do live in a bit of a hilly place. With temps going to 50s and below I have been using my seat heater and cabin heater so did 58 mpg on my last tank. I think when the temps get better I should maybe be getting 65mpg tanks since I have been improving?

    Does the C have an EV button?
