I know cold air makes more horsepower but if winter gas give you worse mileage shouldn't we be making less power too?

I'm getting almost exactly what I got in my 08 Charger, about 17MPG, so I'm happy. I've had 3 hemi vehicles now, a 2003 Ram, a 2008 Charger, and my 10 Challenger, and they all ran really great in cold weather, the Challenger seems to like it even more than the other ones did. It was in the single digits a couple days ago, and it actually had a really good "hit" when I pushed the pedal to take off from a light or stop sign.

I never get into my baby until the engine is at peak operating temperature. Cold air = MOPOWER!
