It's been posted before over at cleanmpg.com. I copied the torque curve from there and have attached it.

I don't think that plot shows the torque provided by the electric motors... so its not the whole story of what you'd feel.

Re: Graph of power curve?

If I were you, I would like to see something like following chart on slide 42 about the Ford engine...

It shows the best efficient rpm and throttle level.
Anyway, the presentation is about Toyota's THS system, but we'll learn a lot of things from it.
