In a sense, you absolutely correct. It actually has to do with the density
of the air. Cooler air (including moister air) is denser. That does provide
more O2 for out cars to burn. Pilots learn about a factor called density
altitude, which teaches us that hotter air makes less power in the engine
and lee lift from the wings, which leads to longer take-off run. Same
principle applies here - cooler air, more power - car runs better.
