Question

If we recreated the scene from Fast & Furious 7 and dropped a Challenger SRT® Hellcat Redeye Widebody from a C-130 aircraft at 5,280 ft, how much horsepower would it take to drive past it before it hits the ground if you’re 1 mile away?

• Air density @ sea level, 59 degrees, no wind = p = .002377 slugs/ft^3
• Coefficient of drag (flat plate, NASA) = C(d) = 1.28
• Weight = W = 4451 lbs
• Gravitation constant = g = 32.2 ft/sec^2
• Area = A = 197.5" long x 78.2" wide x (1 ft^2/ 144 in^2)
• Vehicle falls flat, wheels 1st, straight down, at constant acceleration with no aerodynamic drag until terminal velocity
• Horsepower needed to accelerate is AVERAGE - not peak
• 100% driveline efficiency
