Energy in = energy out
I really can't be bothered to do the calculations right now, but fuel (be it diesel, gasoline, LPG, whatever) caries a set amount of energy. You convert this to heat, and transfer it to motion, causing the car to move. It's starting to look like the MPG (I hate to use M and G, but ok) is getting closer and closer to cars getting more energy out of the fuel than the fuel actually holds.
When will they reach total equilibrium, where all energy from the fuel is converted into motion, with no heat loss at all?
