Two recent car-to-car crash tests of Phase I Marina Safety Research Vehicles (SRV) devel- oped by British Leyland Motor Corporation are described. The tests included a central head-on collision of a Marina SRV with an American Machine and Foundry Corporation (AMF) experimental safety vehicle at a closing speed of 60 mi/h and a 90-degree side impact of the Marina SRV by a modified production Marina automobile at a speed of 30 mi/h. The objective of the test program, which was performed by Calspan under a contract with the National Highway Traffic Safety Administration, was to evaluate the safety performance of the Marina SRVs from the vehicle and occupant responses measured in the crashes. Based on current injury criteria, the test results indicate that human occupants probably would have sustained only minor, if any, injuries in either of the collisions.
