The Gremlin looks like it did beter than the Pinto & Vega. But then again, the Ambassador was a lighter car than either the Impala or Galaxy.
1971 would have been with the 1st gen safety equipment. I believe that was close to when shoulder belts were mandated. I remember my old rambler had the optional shoulder belts, safety glass in the windshield, & a collapsible steering column.
For as bad as those crashes looked, the 50's & 60's were much worse. There is a vid of a 1959 Bel Air crashing into a 2009 Impala. The Bel Air does not fair well because of its X-frame & inline six.
