Well, I designed the formula with MPH more or less in mind, this could

be why you're getting underpowered cars... Perhaps if you multiplied the NPU^2

by about 1.5 afterwards the numbers would balance better (sorry, I'm terrible

with KM to Miles ratios--anybody wanna give the correct ratio here?)

Thanks for catching that one... oops

Hmmm... the coment you made later about this giving you better economy with a

bigger engine probably reflects a flaw in this equation... sinec we're looking

for a km/unit ration we've got kg*kmph on top and just kg on the bottom, thus

right now, the measurement of economy is in km/hour... I don't think that's

quite the ratio we want just yet ;) So, that means we're missing something on

the bottom, probably liters/mile... I'd suggest multiplying by say engine size

on the bottom, and that should yield a better number...

thus the formula changes to:

Economy = Power/((2*Weight)*EngineNPU))

I think that might work better...
