Dunno about the 2010 on up models, but the 04-09 models are a bit
skittish.  OTOH, I've learned to deal with it to the degree that I don't
notice it anymore.

Trust me, 10 deg F and high winds to drive against will pull that baby
down to between 30 and 35 mpg in the blink of an eye.

Now on my second Prius and living in an area with both wind and temperature
extremes (western Minnesota) my worst tank ever was 48 mpg.  Yes, one can
achieve lower instantaneous readings.  Perhaps this is what you mean by "in
the blink of an eye."

No, I meant tank average.

Driving on the freeway against headwinds at 10 deg F, with the cabin
heat on becuase *I* want to be warm, is not the Prius's strong suit.

35mpg at best.

I've never consumed an entire tank at high speed in cold weather against a
strong headwind.  I once consumed an entire tank at high speed in warm
weather with a strong tailwind and averaged 70 mpg.  I suppose the average
of our experiences would be 52.5 which is very close to the lifetime mileage
(only 20K miles) on my 2010.

What's the MPG hit in the northern winter?  Are they still skittish in
cross-winds?

I've experience a mileage hit of about 5% at temperatures as low as -30F.
No surprise considering the energy required to deal with fluids and cabin
heat at such extremes.  Skittish in cross-winds?  Nothing compared to the
SUV and Mini-Van I previously owned.  As far as wind is concerned, the Prius
does well at minimizing the effect of a headwind and maximizing the effect
of a tail wind.  You should drive one some time.
