Now... the real question is... Are any of you doing anything differently in winter to combat the cold?

Last winter I was getting about 33 MPG in a FEH. But it was brand new, not broken in, and neither was the driver.

This winter ( so far ) I'm a more experienced driver, the car is broken in, and I block my radiator with a combination of cardboard & styrofoam.
I think this gives faster warm-up times, and keeps things warmer, longer when in Electric Only Mode.

I'm in North Colorado, nights 10'F, days 45-50'F and am getting 37 MPG this winter.
