Here invented are efficient road vehicles having special aerodynamic shapes, with stabilizing provisions that enable aerodynamic efficiency. It is a vehicle that is configured to include a carriage part that encloses a driver and passenger riding in tandem. This car width is for persons seated in single file, enabling a narrow width that makes a body shaped like an airship practical, where that shape is characterized by a very low drag coefficient in free flow conditions. This body is elevated on struts above a wheel system to enable such free flow aerodynamic conditions, thus, the drag coefficient of the airship is made applicable to this road vehicle. The wheel system includes wheels on each side of the vehicle that are arranged in horizontal columns, to which the struts are attached. The horizontal columns act as individual aerodynamic entities that function independently of the carriage aerodynamic operation. Because this car has both low frontal area and low drag coefficient it will require minimal energy for high speed operation.
