Transmission + motor question

Crash

Actually, I can tell you how much power is required to defeat the rolling resistance and drag (assuming that the wind-speed is 0MPH!):

NOTE: I couldn't find the frontal surface area on the 370z, so I'm GUESSING it's around 1.9m^2. It could be less.

First figure out how much drag force there is:
F_drag = (Drag Coefficient) * (Frontal Area-meters) * (Volocity-Km/s)^2
200MPH = 89.42Km/s
F_drag = 0.29 * 1.9 * 89.422 = 4405.76 N

Now we figure out the rolling resistance:
F_tire = (Vehicle Weight-Kg) * 9.8 * (drag_contribution)
F_tire = 1506 * 9.8 * 2.43% = 358.64 N

Now calculate how much power is needed to push against these forces:
P = F * V
P = 4764.4 * 89.42 = 426032.648 Watts = 571.32HP

So, approximately 571HP is needed to get the car to 200MPH
