Undrgnd - a Prius is a tough car to coax great numbers from in winter.

If you're finding it a challenge, my bet is your typical use is either (a) high-speed freeway driving (always makes it difficult to beat the EPA), or, (b) short distance sub/urban with a significant proportion of trip distance below full operating temps (particularly hard on a hybrid because the engine shuts down much less than it might otherwise).

Neat car, though. I haven't tried an '10 yet but would like to.
