    It all depends on your commute, where and when the fast portions are and the ratio between fast and slow. It makes a huge difference in my commute as the fastest part of my outward commute is almost immediately, and if I use EV for it, I get an easy 20MPG less over the whole day if I don't save EV for the slower part. The difference is really quite striking!

    I have noticed that the Prime is way easier to effect the MPG by how you drive than my 2010 Gen3 Prius. For that 20MPG higher I mentioned above, I can get an additional 20MPG by just going the speed limit and accelerate slower, so 70 MPG now gets close to 110MPG. My 2010 got anywhere between 42 and 49 MPG no matter what, only winter causing the low end and summer the high. (17" wheels and same commute as I have now)

    My commute is 70 miles a day without any extra driving...

    It's a shame the Prime couldn't "learn" your commute and optimize the battery use for you.
    Maybe key off a pre-programmed trip in the NAV and then compute the best places to use gas for an optimal day...

    I've mentioned that want before, a real Auto-EV mode. :)

    You'll see how EV Auto works in this video. At 8:30 mark, he switches into EV Auto (and then he changes from PWR to normal). You'll see him merge across the main street in EV mode and left onto the onramp still in EV. Partway down, he accelerates harder and the engine kicks in. That's exactly how EV Auto was described.

    Does the UK have EV auto?
    From what I can figure out we have EV, HV, Charge and EV city. Is EV city the same as EV auto?

    We suspect your EV is our EV Auto. There's no North American equivalent of EV City and there's no European equivalent of EV mode in the North American sense.

    In EV mode when I tested the car it stayed in EV mode even with my foot to the floor.
    I thought EV City was a lower powered EV mode but not sure what happens if you floor it.

    Hmm that's interesting. We were under the impression that European didn't get a full EV mode.

    EV City is a lower powered EV mode (so no dual-motor drive) to ensure that the battery charge lasts as long as possible within the CBD limits. Supposedly there's a detenté on the accelerator so if you're in EV City and you push pass that detenté, it will kick the engine in. (Similar to the downshift feature on other European automatic-equipped cars)

    Here's the excerpt from the European press release.

    I obviously didn’t put my foot down far enough! Oh well, it was too fast for normal conditions so I guess I don’t ha e to worry about the engine coming on.

    This is what I've pieced together from various sources.

    NA(North America) EV mode is the only mode that is truly EV only, with the ICE only coming on when the charge gets low. It exists because any talk of blended mode was deemed a sales killer in the US. Without the availability of the ICE, its max power and speed are less than hybrid operation.

    EU EV and Auto EV are the same mode. It is EV whenever possible, with the ICE available when needed. The thresholds to ICE activation are far greater than what the PiP had. Depending on route and driving style, the car could remain in EV for the entire grid charge.

    EV City is viritually EV only with lower power output. Except, that there is a 'kick down switch' when the throttle is floored that activates the ICE.

    Has the no dual motor operation in EV City been confirmed, or are we still just working off the modes power limits? It is a fair conclusion, but we don't know that M/G1 gets called upon only once M/G2 reaches max output.

    The downshifting of automatics with a hard depressed throttle isn't a European only behavior. In the days of mechanically controlled automatics, there was a cable connecting the accelerator and transmission that activated the downshift. It was called, get this, the kick down cable.

    It hasn't been confirmed (The only way is if someone in Europe could chat with a representative either at an auto show or directly at HQ).

    Cool didn't know about the kick down cable.

    I've noticed exactly the opposite. When my wife would drive my old Prius, she would get 20-30% lower mileage than I would on the same route. On the Prime the difference is nearly zero.

    They wished for it, and got it. What is so difficult about bending a bit, pushing the HV/EV button and holding it to drive in EV, ICE, and charge mode ? I will admit it took some time for me to totally acclimate to the car, but I finally got it. Worse conditions: going uphill, 2000 feet, totally out of charge, = 112, 80, 60 mpg !
    Best conditions: = 200 mpg +
    now, how can you beat that ?
