and a mechanical fixture of the at least one outlet air flow-enhancing device to the vehicle, the mechanical fixture having movable supports configured to allow changes in attitude and positioning of the at least one outlet air flow enhancing device; wherein the hood air outlet opening and the two lateral-wheel outlet flows are affected by aerodynamic changes to the vehicle by not directly affecting changes in the exterior contours and shape of the vehicle. ## Claims ### Claim 1 In a vehicle having exterior contours and shape and an incoming wind entering a central air main inlet and two front-side air opening inlets, and exiting respectively as a hood air opening outlet air flow and two lateral-wheel outlet flows, an engineering apparatus to affect airflow and to enhance vehicle performance, the apparatus having: at least one outlet air flow-enhancing device configured to enhance and modify the hood air outlet opening and the two lateral-wheel outlet flows, the at least one outlet air flow enhancing device having an x-axis, a y-axis, and a z-axis, the axes mutually orthogonally oriented; and a mechanical fixture of the at least one outlet air flow-enhancing device to the vehicle, the mechanical fixture having movable supports configured to allow changes in attitude and positioning of the at least one outlet air flow enhancing device; wherein the hood air outlet opening and the two lateral-wheel outlet flows are affected by aerodynamic changes to the vehicle by not directly affecting changes in the exterior contours and shape of the vehicle. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein the at least one outlet air flow-enhancing device has an air-turbine configuration with a front end and a rear end. ### Claim 3 (depends on 2) The apparatus according to claim 2, wherein the wind enters the front end and is thrust out of the rear end, substantially coaxially with the x-axis. ### Claim 4 (depends on 3) The apparatus according to claim 3, wherein the at least one outlet air flow-enhancing device is powered electrically. ### Claim 5 (depends on 4) The apparatus according to claim 4, wherein an estimated preferred weight of the outlet air flow-enhancing device ranges from 22 to 27 kilograms. ### Claim 6 (depends on 1) The apparatus according to claim 1, wherein the at least one outlet air flow enhancing device includes a drive shaft connected to and configured to drive a propeller, the drive shaft mechanically connected and driven by a drive gear apparatus, supported by and rotated upon a support shaft. ### Claim 7 (depends on 6) The apparatus according to claim 6, wherein the drive gear apparatus is driven by a front wheel drive system, which includes: a front wheel axle drive and support shaft; at least one front wheel drive gear apparatus driven by the front wheel axle drive and support shaft; a drive belt driven by the front wheel axle drive and support shaft; and a forward gear apparatus driven by the drive belt. ### Claim 8 (depends on 7) The apparatus according to claim 7, wherein the drive belt is a belt, fabricated from a combination of fiber and strong, flexible material. ### Claim 9 (depends on 8) The apparatus according to claim 8, wherein the drive belt has a reinforced chain structure. ### Claim 10 (depends on 9) The apparatus according to claim 9, wherein the drive belt is configured to transfer rotational movement of the front wheel gear apparatus to rotate the forward gear apparatus. ### Claim 11 (depends on 10) The apparatus according to claim 10, wherein the forward gear apparatus is configured to mesh and to drive the drive gear apparatus, thereby providing rotational movement of the propellor. ### Claim 12 (depends on 11) The apparatus according to claim 11, wherein a forward support system is mounted mechanically to the vehicle, the forward support system including: a forward horizontal support shaft; and at least one forward “T” coupling configured to support the drive gear apparatus. ### Claim 13 (depends on 12) The apparatus according to claim 12, wherein the forward horizontal support shaft is further configured to mechanically support the forward gear apparatus. ### Claim 14 (depends on 13) The apparatus according to claim 13, wherein at least one additional outlet air flow enhancing device is configured to be driven by the forward gear apparatus. ### Claim 15 (depends on 14) The apparatus according to claim 14, wherein an estimated preferred weight of the outlet air flow-enhancing device ranges from 22 to 27 kilograms.
