The drag reduction for a two-vehicle platoon is documented by an extensive set of full scale experiments conducted on El Mirage dry lakebed, using two Ford Windstar minivans. The drag forces are measured with the aid of a tow bar. Three series of experiments were carried out: i) coast-down experiments for a single vehicle with transmission set to 'Neutral' position; ii) coast-down experiments for a single vehicle with 'Free-wheeling' hubs mounted on the drive wheels (to eliminate transmission/engine influences); iii) two-vehicle close-following experiments consisting of an acceleration phase and a deceleration phase. The acceleration phase is used to estimate the drag of the trail vehicle, and the deceleration phase is used to estimate the drag of the lead vehicle.
