I don't know about everyone else but after reading that, I am going to have all of these calculations going on in my head while driving down the road.LOL The newest of which is the cold air temp robbing my MPGs. :E
Thanks for the interesting info!
Aerodynamic drag changing with temperature should come as a big surprise. More molecules to "hit" at colder temperatures.
I KNOW pilots know this. Heck, this summer we just flew non-stop Dallas to Sidney, Australia. Airbus 380. Sold out flight. 1/4 seats EMPTY. With hot temperature in Dallas, not enough lift (not enough air molecules passing over/under the wings) with full plane (ya and enough fuel for the 17+ hour flight).
Our MPG in summer running the dash air is still better than freezing temperatures trips without the compressor running.
