A fuel saving system includes a vehicle. A housing is coupled to the vehicle and the housing captures air when the vehicle is driven. A baffling unit is coupled to the housing and the baffling unit selectively inhibits the air from entering the housing. A turbo is rotatably positioned within the housing and the turbo is rotated by the air passing through the housing. Thus, the turbo produces rotational torque. A drive is coupled between the vehicle and the turbo. The drive transfers the rotational torque to the vehicle thereby increasing a fuel efficiency of the vehicle when the vehicle is driven.
