A system for reducing turbulence and therefore improving fuel efficiency for land-operated vehicles uses at least one linear array of vortex generators along typically a leading edge of a vehicle profile. I addition an aerodynamic bug diversion system is provided for creating and directing an airflow shield to prevent bugs and other lightweight debris from hitting the windshield of a moving vehicle.

1. An airfoil for directing an airflow shield to prevent bugs and other lightweight debris from hitting the windshield of a moving vehicle comprising: a base foil having a forward protruding lip for collecting incoming airflow and an upright curvature substantially following the angle of protrusion

1. An airfoil for directing an airflow shield to prevent bugs and other lightweight debris from hitting the windshield of a moving vehicle comprising: a base foil having a forward protruding lip for collecting incoming airflow and an upright curvature substantially following the angle of protrusion of the windshield from the vehicle; and an upper foil connected to and spaced-apart from the base foil by a plurality of support fins creating a plurality of separate airflow channels, at a position elevated from and substantially parallel to the base foil; characterized in that the channels formed between the upper and lower airfoils by the plurality of support fins function to redirect airflow in a path substantially parallel to the windshield, forming a bug shield of moving air, and the spacing of the base foil and the upper foil is adjusted to a level at which the windshield become bug free.2. The airfoil of claim 1 wherein the upper foil is held rigidly above the base foil by the plurality of support fins, the fins aiding in channeling the airflow.3. The airfoil of claim 1 wherein the airfoil is formed of one polymer piece in a molding operation.4. The airfoil of claim 1 wherein the airfoil is formed of 2 or more polymer pieces and is assembled.5. The airfoil of claim 1 wherein the airfoil is formed of aluminum.6. The airfoil of claim 1 wherein the airfoil orientation is adjustable.7. The airfoil of claim 1 wherein the base foil has at least two windshield support feet adapted as standoffs to the windshield.
