I Have a Question

So .... is it true that a car will develop more power in cold weather due to the denser air?
If so, is that advantage not lost due to a higher density of air causing more wind resistance?

Power and speed are different attributes, of course. So yes, denser air creates more power. Density Altitude seem to have far greater effect generating power than any drag/resistance they create. In drag racing, the sweet spot for times seems to be cooler day, but still warm enough for good traction to transfer power. Too cool and the traction suffers. Too hot and the power suffers. I've never seen anyone calculate differences in drag/resistance - at a track.
