Ken,
thank you for your thoughts. We certainly think about things differently, but obviously there is one physical model which is the real world.
My idea starts with the idea of looking at where fuel goes towards. Fuel goes towards 3 main topics, then from there gets split down.
First, fuel heats the radiator.
Second, fuel heats the exhaust gasses out the tail pipe.
Third, fuel creates exhaust gasses which push the car.
Fourth, fuel creates energy which gets thrown away by pumping losses and the like.
Of the third topic, there are three main resistances to pushing the car around. There is weight (1/2 mvv). There is aero resistance (vv*Cd*Frontal area). There is rolling resistance.
We can back into real world with the math, eventually.
We can come up with excuses as to why all the investor money is gone, but the car is not designed yet.
Or, as you did, we can take some educated guesses, and start laying the car out and get it done.
