The objective of the paper was to apply to the NCAP star rating system injury risk functions that are more representative of the injury tolerance of older occupants. The NASS 1998-2008 data for front outboard occupants in NCAP like frontal crashes protected by air bags and safety belts was analyzed to determine injury risks by body region and occupant age groupings. The injury rates for NCAP like crashes were calculated for each applicable body region. Alternative injury risk functions were applied to 302 NCAP tests of vehicles model year 1988- 2006. NCAP injury rates were calculated and compared with NASS data. The comparison was used to select injury risk functions to be applied to 2011 NCAP tests. Selected risk functions from the literature that produced injury rates in NCAP tests like those in NCAP like crashes were substituted for NCAP 2011 chest and neck injury risk functions. When applied to the 2011 NCAP tests there was a general downward shift in the star ratings awarded to the driver. However, the number of passengers with 5 star ratings more than doubled. For both drivers and passengers there were vehicles that advanced from 4 stars to 5 stars. The application of this alternative rating system would produce added incentives for safety designs that more correctly prioritize the reduction of injuries most harmful to older occupants.
