| Power = 8.702 x 10^(-6) x Cd x A x V^3 where Cd = coefficient of drag
A = square feet of frontal area of the vehicle
V = velocity, in miles per hour I've found various numbers for Z32 Cd and frontal area, but let's go with Cd = .32 and A = 19.5 ft^2, then Required Power = (8.702 x 10^(-6) x.32 x 19.5 x 200^3 = 434rwhp Up it to 220mph = 578rwhp Remove 1 sq ft from the frontal area, and drop the requirement to go 200mph to 412rwhp, and 220mph to 548rwhp.
