    In Germany the typical passing power of a vehicle is measured between 80 km/h (~50 mph) and 120 km/h (~75 mph) and it takes my gen. 3 about 7 sec. to do so,which is pretty good.
    I came across this video and as it seems it takes the Prime more than double of the time to get from 50-75 when in EV !
    So I was wondering if the guy in the video is wasting time by not pushing the pedal to the metal straightaway as he should when testing those times!
    I noticed that the power meter goes up immediately right to the end when he does the same precedure in HV mode,but it seems to take the power meter some time to go right to the end when in EV,so what is your opinion?
    Is it really that slow,is the car maybe going uphill or is the reviewer not pushing hard enough on the pedal ?
    By the way the Prime even seems to need about 2 sec. more even in HV -mode vs. the regular Prius doing 50-75.

    If you are going to pass aggressively, why would you leave it in EV mode? That's what EV-Auto is for.

    My commute takes me on a stretch of highway that has a 70 mph limit. Driving through that traffic and passing in EV mode is all I've ever needed.

    This is exactly the same experience I have. The EV mode is designed for inner city driving, not for hwy. You need to take the car out of EV mode and into HV mode on hwy.

    There was posting that claimed ascending a hill someone floored the car and the car switched to HV mode by itself under load. If the battery is about gone, this would make sense as it exhausts the last charge. But I thought the OP claimed that was not the case. Regardless, I have yet to see a reproducible case of the car leaving EV with charge and enabling the engine.

    Anyone else?

    The EU Prius PHV is different from the Prime in this respect. PHV EV mode is actually somewhat similar to Prime's EV auto mode, so, in Germany no need to switch, ICE will kick in at very high loads.

    In the video is US spec Prime, it will stay in EV even if you floor it.

    EU spec Prius PHV will engage engine on the kick down, no matter what mode you are in. So I don't know if that will satisfy @civicdriver06 or not. In a way it will give you more passing power but you will be burning gasoline. My take is if you wan't high speed performance then engaging ICE is inevetable, so it may as well engage ICE on kick down.

    I drove my Prime up to 86mph on the highway before it automatically tripped out of Ev mode. It tripped when the speed changed from 85 to 86.

    I've driven in Ev on the highway for hundreds of miles so far - like every single day to work. Part of my trip to work is an acceleration from 0 to 50 up a 7% grade. No issues in Ev mode.

    I've done 0-60 and 30-60 testing on the highway in Ev mode. No problem staying in Ev mode.

    Yesterday, I put the pedal on the floor at 0 and took it off the floor at 62mph while climbing a 5% grade. Stayed in Ev mode the entire time.

    Again, please be aware of the differences between the NA-spec and Euro-spec cars. :) There is no 100% EV mode in Euro-spec cars.

    Then I wouldn't buy one, and in fact I didn't buy a PIP partially for this reason.

    The Euro-spec car suits me better than the US-spec one.
    In EV mode the engine kicks in only when you floor the pedal and activate the kick-down switch (i.e. - extra pressure), this is a very very rare situation for me and when it does happen I do want all the power available no matter which source it comes from, and both sources together do give lot of extra power (91 kW as compared to 68 kW EV only).
    Comparison to the PiP EV mode is really irrelevant.
