I did the math before in the other thread, but now I'll do it for 170MPH (Again, assuming that the wind-speed is 0MPH!): NOTE: I couldn't find the frontal surface

I did the math before in the other thread, but now I'll do it for 170MPH
(Again, 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 170MPH = 75.99m/s F_drag = 0.29 * 1.9 * 75.99^2 = 3181.74 N Now we figure out the rolling resistance: F_tire = (Vehicle Weight-Kg) * 9.8 * (drag_contribution) F_tire = 1506 * 9.8 * 1.8% = 265.65 N Now calculate how much power is needed to push against these forces: P = F * V P = 3447.39 * 89.42 = 308265.6138 Watts = 413HP I double checked my math and it's right. I still think this is pretty high. Can someone find the REAL frontal area on the Z? I think that's making this number high.
