In 1995, the Insurance Institute for Highway Safety began a program of crash testing to evaluate important aspects of crashworthiness of new passenger vehicles. The major component of the evaluation is a 40 mi/h frontal offset crash test of each vehicle into a deformable barrier. The crashworthiness of each vehicle in the frontal offset test is based on criteria assessing structural performance, injury measures obtained from a 50th percentile male Hybrid III dummy, and restraint performance and dummy kinematics. These tests are designed to complement the U.S. government’s 35 mi/h full-width banier testing in the New Car Assessment Program (NCAP). Good performance in both tests should be the goal for frontal crashworthiness designs. The results obtained from 16 midsize four-door passenger cars and 6 midsize utility vehicles indicate large differences in performance among the vehicles in each group. Several of the cars with good performance in offset tests also performed well in NCAP tests demonstrating that the two tests need not produce design conflicts.
