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?

Yes in colder weather your car will have more power because colder air has more molecules which makes it more dense. The denser the air the more oxygen is in it. This creates a better combustion in the cylinders. The downside of this is that your car's computer senses this and increases the fuel to the cylinders. This makes you use a little more gas in the winter time vs Summer
