    And having manual shifters wouldn't improve that figure.

    If you're travelling at speed it may, as downshifting will force the engine to rev harder, getting it ready to be floored.

    Although having said that, i can learn to live with the power delivery lag on the Prius, you just have to accelerate before you normally would. In comparison to Fiat's dualogic robotised tansmission, it feels as responsive as a Ferrari, nothing, and i mean nothing is worse than Fiat's automatics.

    It does if you know how to use one. You put the car in the right gear before you need the power. If you are going to pass, have it in the gear you need to pass before you pull out, if you are going into a corner have it in the gear you need to go through the corner. Then response time is essentially zero.

    "...different shift map..."

    Has no view of upcoming road conditions......only you have that..

    it is much easier to understand when you experience it :).

    IMHO, to me it went from "who cares" feature to "wow, i would never ever buy an CVT without it".

    Don't CVTs have a low gear whatever they're now called? The Prius has B. The HHR has an I. I only use it on downgrades and forcing DFCO coming to stops, but it exists to improve the performance response of the transmission on the hills and in the twisties. It holds gears longer and is more aggressive in downshifting.

    Why is a change in the transmissions programing from a button or lever switch not possible or unacceptable with a CVT or even step?

    I have yet to drive a CVT, but my attitude with manual modes on step transmissions went the opposite way.

    I am really confused by what people are wanting. Do you want more options on your Prius? Some other form of transmission on your Prius? Some other car?

    For a current transmission Prius, please describe in terms of this Toyota Prius - Power Split Device what you want it to do. Thanks.

    the annoying hybrid delay could be cut in half with K&N filter :)

    And it could be completely eliminated with a turbo decal.

    In short, a tiptronic manual mode on the Prius transmission would be great :)

    wait, seriously?

    I think it means the PSD has to be beefed up and will make the car heavier and less efficient.

    It wouldn't have to be beefed up at all as long as it was restricted to the ratios and maximum power levels it's restricted to now.

    A manual mode where the ICE runs constantly, with artificial gears for the transmission, controlled by paddles or the gear lever, like the Insight has.

    From my understanding, adding a manual shift mode to a transmission is purely a software change, plus shift paddles and changes to the shift lever - i don't think it would be too hard for Toyota to implement.

    The Prius has one "manual gear" - B mode. It allows tighter control of power/braking with only the gas pedal. Having multiple B mode calibrations would provide even better control.

    It would mean that the ICE was operating in less-eficient BSFC areas of the chart rpm-torque.

    Guess so. I never felt a lack with the gen2 transmission, and the autos with manual mode I drove were just meh.
    What?...Why?...I think I'm going to be sick.
    They already have. They call it Power mode, and B isn't disabled with it. It doesn't have all the driver interface some crave, but it's a Toyota Prius, a family, except in name, wagon/hatchback. Imagine the complaints on fuel economy if the gen2 had power mode.

    Honda caught flak for the Insight2 trying to be like the Prius, and now you want the Prius to be more like it. If you want a more performance orientated hybrid, buy a Honda. Their cars already tend to be sportier than Toyota's, and they even have a sporty type hybrid.

    Sudden change in ICE power (jerk) will have to be handled both mechanically and electrically. Sure software change can allow higher ICE rev as we have in CT200h Sport mode. To get the real gear shift jerk feel, we'll probably going to need the inverter size from Camry or Highlander hybrid.

    MPG may suffer like CT200h as well.
