If we are looking at doing a second loadable program that would do a coastdown to calculate the Cd, Crr (and Cskin?), would it be possible to include the engine's efficiency as an output?
Variables needed:
- Cd
- Crr
- (Cskin if we calculate it)
- Area
- mass
We can calculate power and use a standard number for gasoline (or diesel) BTU/gallon, and we can get efficiency. I think it would be useful for people that want to do P&G to know where their engine is most efficient. They can then verify that with MPG.
