An airfoil roof incorporated into or added onto a vehicle roof in the form of a longitudinal tunnel that is open at the front and closed at the rear which enables air to pass into the forward end of the tunnel during forward movement of the vehicle with the closed rearward end of the tunnel catching such air which causes a limited lifting force to be exerted on the vehicle to, in effect, reduce the weight of the vehicle thereby reducing the energy required to propel the vehicle over a road surface thereby resulting in energy conservation by enabling a vehicle to be propelled a greater distance while consuming a given quantity of fuel which results from the decrease in weight and the reduction in rolling resistance and fricitonal resistance between the vehicle tires and road surface.
