    Hmm
    I couldn't find the Prius 0-60 times??
    8.6 wow-that is quick for a MPG car/suv -sure explains the less than Prius mpg- no free lunch!!

    Wayne- maybe you looked like some Allah Ackbar terrorist lurking outside a military base
    Lucky they didn't sic a Drone on you (maybe they did?)

    My 2006 Prius seems pretty peppy in city driving- not sure how it would be if I needed to pass some truck that was doing 60 on a 2 lane road-but unlikely I would ever feel that need

    I agree the 3rd gen Prius HSI display/monitor needs to be under the PWR level band inorder for the Prius to get achieve better fuel efficiency. I want to emphasis that in hilly areas or in stop-n-go traffic driving environments, the Prius needs to be in Normal or PWR throttle/mode because the Prius needs to use the ICE sooner-than-later to avoid draining the Traction battery (this is less of a problem with the Prius Plugin).

    I didn't mention Warp Steath Mode because IMHO it really takes a FE gauge like the ScangaugeII or Andriod Torque to do it optimally - the Prius' HSI display (which is a aggregate power monitor) is often all over the place in Warp Steath mode. (9_9) I wanted to avoid suggesting anything that required special equipment. I found that Warp Stealth needs something more direct like an RPM/GPH xgauge to do well. I'm not against having a third party fuel efficiency gauge ....I've got two scangaugeII connected to my Prius (HyperDrive1) but my experience with most people is that its often a bit much .... just getting a driver to get and use a scangaugeII is a signficant jump in effort/committment toward fuel efficiency. Hence, my tendency to soft peddle ...

    Hi All:

    I have not yet made it home but a few hours from now I will :)

    Charlie, the 0 to 60 times were posted in the following: http://www.cleanmpg.com/forums/showpost.php?p=368111&postcount=248

    Wayne, you might find this amusing. It is blurry but the battery is full all the way to the very top. Even the post on the top is blue. I know, not the best but I was cold and had the heat on. Still working on the SOC for the scanguage. He just sent me something else to try. This shows 120% full. As soon as I have that I will post it. Oh, and yes the instant mpg is 7.9.

    Hi Rich:

    You like seeing pretty colors or something ;)

    I finally got home and am going through over 400 e-mails (mostly junk) so should be catching up over the weekend. This includes the steady state graphs for all three.

    Excellent, how about a graph with all 3 ?

    Well, on the bright side the C-MAX dropped the least from 50 mph to 70 mph. Have to always look at the bright side right?;)

    C-MAX 51.3 - 38.1 = 13.2 mpg drop
    Prius V 60.1 - 43.1 = 17 mpg drop
    Prius 65.3 - 45.5 = 19.8 mpg drop

    Only because you're looking at fuel consumption inversely, per U.S. custom. Doing a little arithmetic with the same data reveals the C-Max actually had the largest increase in fuel consumed per mile with increasing speed, which is consistent with its higher aero drag.

    Hi Rich and Herm:

    I was working on the 3 vehicles combination chart when you posted.

    Sorry, my sarcasm doesn't always come through so well.

    Oh, I recognized the sarcasm, but still wanted to point out how "mpg drop" can obscure things. To be more specific:

    C-Max: 1/38.1-1/51.3 = .00675 increase in gallons/mile
    Prius V: 1/43.1-1/60.1 = .00656 "
    Prius : 1/45.5-1/65.3 = .00666 "

    Where is the plot of the Prius V with the 16" box strapped to the roof? :)

    Hi Herm:

    The v's 16" x 16" box fit inside the rear hatch with room to spare ;)

    Any idea how they compare at 40?
    Just interested.....

    Hi Gord:

    That would not be easy to achieve as it is to slow a speed for the highway and too fast and short for most boulevards in suburbia let alone having to take into account the pack cycles. The C-MAX was a problem at 50 and 55 mph as I had to drive more than twice the normal 10 + mile distance to come across a SoC at 50% AND the elevation start and finish within +/- 10 ft. while on the I-10 in Phoenix.

    The least confidence I had with the above was with the v as it was turning from dusk to dark and winds were dying off on one side and picking up on the other while I was still acquiring data. I wish I could have completed all of the above at home as I know the elevation profiles within +/- 20 ft. over my 40 mile one way N-S and S-N route.
