In September 2009 the National Highway Traffic Safety Administration (NHTSA) published a report that investigated the incidence of fatalities to belted non-ejected occupants in frontal crashes involving late-model vehicles. The report concluded that after exceedingly severe crashes, the largest number of fatalities occurred in crashes involving poor structural engagement between the vehicle and its collision partner, present in crashes characterized as corner impacts, oblique crashes, impacts with narrow objects, and heavy vehicle underrides. By contrast, few if any of these 122 fatal crashes were full-frontal or offset-frontal impacts with good structural engagement, excepting crashes that were of extreme severity or the occupants that were exceptionally vulnerable. The intent of this research program is to develop a test protocol that replicates real-world injury potential in small overlap impacts (SOI) and oblique offset impacts (Oblique) in motor vehicle crashes. Previous work towards this goal has led to the development of a Research Moving Deformable Barrier-to-Vehicle (RMDBtV) test protocol, which is further evaluated in this paper. While there were some inherent differences in the Vehicle-to-Vehicle (VtV) and RMDBtV test results, the overall agreement of vehicle and occupant responses proved promising enough to perform another VtV to RMDBtV comparison. As in the previous study, the first step is to compare the RMDBtV to VtV test for the same vehicle. This comparison f...
