Aerodynamic drag force ($F_{air}$) increases with the square of vehicle speed ($v^2$). How does the engine POWER required to overcome aerodynamic drag scale with vehicle speed?

1. Power required to overcome aerodynamic drag scales with the CUBE of speed ($v^3$)
2. Power scales linearly with speed ($v^1$)
3. Power scales with the square of speed ($v^2$)
4. Power is independent of vehicle speed
