A wheeled vehicle, comprising:
- a frame configured for supporting a driver and/or a plurality of mechanical devices, wherein the frame is defined as having a front portion, a rear portion, a vertical cross plane, a right portion, a left portion, and a vertical center plane, wherein the front portion is opposite the rear portion and is generally divided by the vertical cross plane, and wherein the right portion is opposite the left portion and is generally divided by the vertical center plane;
- a pair of steerable front wheels rotatably affixed to the frame positioned at opposite sides of the front portion generally equally separated by the vertical center plane, and wherein the pair of steerable front wheels rotate in both a pair of rolling axes and a pair of turning axes, wherein the pair of rolling axes allow the pair of steerable front wheels to roll upon a surface wherein the surface is substantially perpendicular to both the vertical center plane and the vertical cross plane, wherein the pair of rolling axes are substantially parallel with the surface, and wherein the pair of turning axes are substantially parallel to both the vertical center plane and the vertical cross plane, wherein the driver and/or the plurality of mechanical devices are configured to change direction of the pair of steerable front wheels relative to the orientation of the frame about the pair of turning axes through a steering input;
- at least one rear wheel rotatably affixed to the frame generally positioned about the rear portion behind the vertical cross plane, wherein the at least one rear wheel rotates in a rear rolling axis wherein the rear rolling axis is substantially parallel to the vertical cross plane and substantially perpendicular to the vertical center plane, such that the rear wheel can roll upon the surface;
- a motor affixed to the frame configured to power at least one of the pair of steerable front wheels and/or the at least one rear wheel;
- a diffuser affixed directly or indirectly to the frame or formed as part of the frame, the diffuser defining a tunnel-shaped void disposed at a bottom of the vehicle and open to the surface, the tunnel starting at a proximal end with a first height nearer to the front portion and increasing to a second height closer to the rear portion, wherein a distal end of the diffuser is open to the rear portion;
- and
- a thruster affixed directly or indirectly to the frame, the thruster having an exhaust outlet, wherein the exhaust outlet is disposed at, near or within the diffuser aimed at the tunnel-shaped void, wherein the exhaust outlet is disposed a distance away from the distal end of the diffuser, wherein the exhaust outlet is configured to introduce a moving airstream into the diffuser thereby increasing downforce of the wheeled vehicle generated by the diffuser while the wheeled vehicle is stationary or moving.
