A drag reduction method and apparatus for reducing aerodynamic pressure drag associated with a vehicle in motion by use of substrates that can perform as turbulators. The substrates can have a texture that increase the momentum of the air in the boundary layer about a vehicle, moving separation points, and reducing low pressure areas thereby improving the fuel economy of the vehicle. The substrate can reduce the effects of the pressure drag by creating a turbulent boundary layer over the surface of the vehicle, moving separation points downstream where they produce less drag on the vehicle. An automated turbulator deployment system is also disclosed that provides improved aesthetics and can tailor the aerodynamic profile of a vehicle based on the current aerodynamic conditions.
