‘99 Prelude
0.33 drag coefficient
1.75m x 1.315m = 2.30125m2 frontal area
Power = 0.5 * air density * drag coefficient * frontal area * velocity^3
0.5 * 1.2 * 0.33 * 2.30125 * (63.889)^3 / 1000 = 118.824 kW (159 hp)
Doesn’t factor in rolling resistance, but it’s generally negligible at higher speeds.
