    I've never been in Maine.. It is one of the 6 ConUS states I've haven't been yet - on my todo list.

    Around here temps start creeping into 60-70 range, so last tank was 58.3(?) MPG with over 500mi traveled. This is with lower grill vent 50% blocked. And mostly with many 50mi+ trips. It would be much less if your trips <10mi. I'd say get OBDII/Torque, plot engine temps and experiment with gill blocking. In winter you might be o'k with 100% block. 50% on lower is fine to keep until A/C season kicks in.

    In comparing MPG-wise Gen3 does better in cold, better on highway and just enough power (you really fill this when you get back in C). Much more trunk space, rear leg room. Handling is worse, so are driver the ergonomics. Better visibility and side mirrors.

    I might have this done at some point:

    Dude, take a deep breath. you need to read all my posts not just skim through them until your mad, you can go back through posts from years ago and find out exactly why I got rid of the v, I don't pick on prius, hell I just bought another new one that I like even better than my first one and I liked the first one. however with the exception of the mpg, TO ME, the dodge is a much more comfortable car and I HAVE HAD NO TROUBLE with the more than 5 that I have owned. why are you taking my posts so seriously?

    I plugged it in today and played around (though it was a wet day and I didn't have a chance for clean 0-60 runs.

    From what I've seen so far Torque had reported highest HP 80.7 and 0-60 13.7, which is right on money - what it supposed to be. Not sure how they're getting 10.9 on tests

    ^ this is full throttle acceleration, correct?

    Yes at WOT (which is 80% anyways)

    Torque calculates WHP from weight and acceleration, but it does not take into consideration road incline, so if you are going uphill it will under-report it. The highest I've seen so far was 82.6.

    WHP = HP minus ~15-16%, so it is ~97HP right on money. The slow 0-60 time is somewhat due to me, since I haven't ran a test reliably, but it will still be more than 11sec, for sure. I suspect the issue may be due to software restrictions, so whole whooping 99HP is only available for a few seconds, they restricted it to preserve battery(?)

    Ignorance is a bliss sometimes, but what's WOT?

    I was wondering how exactly they measure torque and power output when the engine is in the car and not on a test stand .. this makes sense.

    yes!

    BTW Torque reports throttle positions btw 14.3% (closed) and 80% (WOT). Interesting that ECU is set up in such way that the only time throttle is in close position is when engine is heating up or car is slowing down. Otherwise it is in mostly nonrestrictive position, so the intake manifold pressure is close to atmospheric.

    That's how you reduce pumping losses.

    Low pumping losses are one of the advantages of a conventional diesel.

    I have noticed, on the infamous "not-even-45-mph-hill" that the battery charge doesn't go down at all. I would have imagined the battery would be contributing to the ICE effort as much as possible until the charge drops to a minimal safe level and then just let the engine cope on its own, but this is not the case.

    Preserving the battery and the engine. The c's engine doesn't feel like 74 hp at all - I must have driven a dozen sub-100 hp gasoline cars in the past, and none of them felt that "careful".

    O.k. I was able to get a couple runs in 11.2-11.6 range with 1/4mile time ~18.5
    Highest HP 85.6 and trap speed 77.1. Need to find flatter road

    You must be a clairvoyant; just a couple of hours earlierI I enjoyed a couple of fragrant minutes, stuck behind a 300d in traffic.

    I own a 2012 Prius II, 3rd generation, and I can't agree with you more. I love that I have 3 modes, EV ECO and Power. Power gets me up any steep hill quickly and efficiently; Eco is great for driving normally; and EV is great for neighborhood cruising. I'm super happy with my choice. I did months of research and knew with gas mileage being the same, I wanted more room in my car for less cost.

    You made a good choice! You're smart! Enjoy your fuel economy and perky accleration :)

    Best of both worlds. No wonder it sales so well

    I own both and while Gen3 is overall a better car it isn't a clear cut. C wins in handling, visibility, driver's ergo. Gen3 carrier-sized dashboard is horrid both as sun collector, fogging and and freezing in wintery conditions.

    The 'c' has ECO and EV mode and I assumed that when it's in neither, it's in Power? What does an explicit Power mode do, other than de-emphasizing the economy objective?

    I'm somewhat amused by posts that argue whether or not the C or regular Prius is a better car. One post argues it far smarter to buy a used regular Prius over a new C if you can afford it because it is allegedly a better car. The simple fact is a person chooses a certain car for a multitude of different reasons. I chose a C because it was the car I wanted. I considered a new regular Prius, but, simply did not like it when I compared it to a C (the C was the best car for me). If I had wanted to I could have bought an Audi or Mercedes, don't like them either. Why do some people feel that if a person buys a different car from them they've made a mistake and that the supposed mistake should be pointed out? To each is own and vive la difference.

    Humans are adorable in general :) - - - but I can elucidate why I ended up with 'c': money. It was cheap. If could afford a regular Prius for $26-27K out the door (which I had never considered), I would have bought a Golf TDI or an Impreza with CVT in a heartbeat. And I wasn't going to buy a pig in a poke second-hand car.

    Perky acceleration is one of the perks Prius is known for :LOL:

    Prius sales have gradually dropped from about 500K units in 2010 to a little above 200K in 2014 - even in the years of high gas prices. Regular ICE cars have become a lot more fuel-efficient, while foregoing hybrids' quirks and extra costs. The novelty has worn off as well.
