This report presents the test results of a front-to-front collision between a fiat 2500 pound class experimental safety vehicle (esv) and a 5200 pound amf esv at a closure speed of 75 miles per hour. The objective of this test was to assist in the understanding of problems associated with crashworthiness in the traffic mix, i.e., car-to-car compatibility and aggressiveness. This crash test evaluated the structural integrity and dynamic response of the fiat esv when involved in a collision with a larger esv. The test also investigated the potential benefits of velocity-sensitive front-end structures to accommodate lighter weight vehicles such as the fiat esv. The test was successful in that fiat compartment integrity was adequately maintained. The amf vehicle's hydraulic system stroked almost 20 inches compared to the 24-inch dynamic crush for the fiat, indicating that the heavier amf vehicle absorbed a significant portion of the crash energy. The coefficient of restitution as well as the fiat vertical and pitch accelerations were determined since these parameters influence restraint system requirements. Since no restraint systems were provided in this fiat structural test vehicle, dummies were not used and occupant injury evaluations were not determined. (Author/publisher)
