I have been driving our '06 Prius for 3 weeks (when my wife lets me) and love it.

I have read numerous articles on increasing fuel economy. Most say accelerate slowly. I have also seen a couple of people suggest that starting more aggresively works better.

When accelerating , the MPG tends to be on the low side, which makes sense.

When accelerating with a 'heavier' foot (not flooring it, but pushing the accelerator 1/2 way or more), the MPG is still low, perhaps just a little lower than when accelerating slowly, but since you get to cruising speed faster, you are driving for less time at the lower MPG.

I have tried both and seem to find that I obtain virtually the same MPG using both methods. I think it may be possible to increase MPG with faster starts.

What is your experience?
