This paper describes the vehicle dynamic test results for the experimental safety vehicles delivered by AMF, Inc., and Fairchild Industries to the National Highway Traffic Safety Administration in January 1972. These test results are concerned primarily with the braking and steering ability of the vehicles and were derived from the early feasibility studies (Phase I studies) that originate within the NHTSA (then called NHSB) in early 1968. From these studies and a subsequent test program, performance specifications were written for the AMF and Fairchild Industries contracts.
