Underwing for a vehicle

A system and apparatus for increasing the safety of motor vehicles traveling at high speeds in the rearward direction is provided. An air dam hingedly secured to the aft end of a vehicle may remain in a stowed position while the motor vehicle is traveling in a forward direction so as not to interfere with aerodynamic performance. When a motor vehicle begins to enter a spin, the air dam may deploy and increase the downward force on the vehicle and as well as act as an air brake, thereby reducing the likelihood of the aft end of the vehicle lifting from the surface during a spin-out at high speeds.

Provided are apparatuses, methods, and systems to clear a road surface of debris, water, or other contaminants. A system for clearing a road surface is provided including an air knife with an elongate orifice extending along a line, a frame configured to support the air knife in a position substantially parallel to a plane defined by the road surface, and a tow bar coupled to the frame, where the tow bar is pivotable relative to the frame along an axis orthogonal to the plane defined by the road surface. The system may include a mounting plate connected to the tow bar, where the mounting plate is pivotably mounted to the frame. The air knife may be supplied with pressurized air to clear the road surface of debris. A guide wheel may be attached to the frame, where the guide wheel is configured to rotate about an axis orthogonal to the plane defined by the road surface.
