A vehicle air turbine has a vehicle body and an air turbine assembly includes an air turbine blade mounted on a turbine frame. The turbine frame is mounted on a rotating axle, and the rotating axle is mounted to the vehicle body. An air inlet is mounted in front of the air turbine with an air outlet behind the air turbine. A front wing is connected to a wing frame to form an airfoil for directing air through the turbine. The front wing is movable relative to the wing frame, and the airfoil is inverted to draw air into the air inlet. A turbine inlet deflector directs air flow towards a turbine inlet portion. A generator can be mounted to the rotating axle for generating electricity.
