^^^ I based the drag contribution on math I did earlier for as similar car. I don't have the spreadsheet on this computer with the calculations, but drag contribution is recalculated based on the speed since speed is not constant, but rather squared. Originally 35MPH was calculated at approx 1.3%, at 200MPH my calculations gave me approx. 2.43%. When I get to my other computer, I'll post up the formula I used to get that contribution.
And, yeah, I've been doing the watts/hp conversion for a while because I've been researching electric cars for a long time, and most electric motors all have specs in metric units instead of imperial. So it's all in KW and NM instead of HP and TQ. I don't see how calculus is needed for the exact number of HP need to achieve a certain speed.
