If Goldberg is delivering presents at an altitude of 5,813.6ft, with the same drag and weight of a 2019 Challenger SRT® Hellcat Redeye, how much HP would he need to reach 400 mph?

Pro Tips

•100% driveline efficiency
•P (air density) at 5813.6 ft = .0019 slug/ft^3
•A (Area of Challenger front end) = 26.72 ft^2
•C(d) (Coefficient of drag) = .398
•Goldberg's sleigh required speed, 400 MPH = 587 ft/sec
•F(drag) = 1/2 p x v^2 x C(d)A
•P = F(drag) x V
•Convert to Horsepower = P ( 1HP/550 ft lbf/sec)
