    I'm curious to know what the PWR mode actually does INSIDE the engine i.e. does it 'step up' the timing &/or fuel flow to the cylinders??? THANKS, J

    Nothing. The PWR mode only effects mapping of pedal position to throttle position.

    It also affects the heating and cooling system.

    The ECO button does, but I don't recall the PWR button doing so.

    Right. The fact when it is in PWR negates the economical settings that could be had in ECO if that makes any sense.

    It'll increase the pedal sensitivity so the engine is more willing to rev up. There's a possibility that the voltage through inverter steps up to 650V vs. 500V in normal or ECO mode but it's never been documented in any Prius documents we've seen (but it has been mentioned in the CT200h documents which share the same hybrid powertrain as the Prius).

    In this sense, PWR is the same as Normal. ECO is the 'different' setting.

    It does one more thing. It makes the driver think he/she is in a powerful vehicle. ;)

    I don't remember where and when, but someone here posted a Toyota presentation on the New Gen IIIs and it showed there was a boost when the power button is used.

    My wife and I have opposite tastes when it comes to cars... when she has to drive the Prius, I tell her "Push the power button right when you get in the car, then you'll be rocketing along unlike me..."

    PWR button use requires JDM neck brace...
