Abstract: Here invented are efficient road vehicles having special aerodynamic shapes, with stabilizing devices that enable aerodynamic efficiency. An embodiment is a articulated vehicle that is tall and narrow. It includes a carriage part that encloses a driver and passenger riding in tandem. This car is only wide enough for persons seated in single file, so it has very low projected frontal area compared with typical cars. Further, the narrow width makes a body shaped like an airship practical, where that shape is characterized by a very low drag coefficient in free flow conditions. Since this body is elevated on struts to enable such free flow aerodynamic conditions, the drag coefficient of the airship is made applicable to this road vehicle. Because this car has both low frontal area and low drag coefficient it will require minimal energy for high speed operation.
