Here are parameters you could consider--
Gasoline engine efficiency.......30% (to the shaft, good for a Prius)

That's a good example of the sort of thing I was hoping to get away from by using an experimental method. Look at BSFC charts: your gas engine efficiency is going to be all over the place, depending on how you drive. If you just measure things over a drive cycle, you don't have to bother about calculating the differing efficiencies.
Might even want to do several different cycles for comparison: (sub)urban stop & go, freeway cruising, rural roads, etc.
Humm... Anybody on an engineering faculty? Maybe you could get a research grant...
