New Car Assessment Program (NCAP) gives star ratings to the vehicles based on their crashworthiness. The program uses results of crash tests performed with 50% male HYBRID III dummies in the driver and right front passenger seats and gives separate star ratings for the driver and right front passenger positions. These star ratings are available from the safer car website [1], and are perceived as an indicator of general safety of the vehicles for people trying to purchase a vehicle. A one-star rating would show the lowest, and five-star would be the highest safety ranking. As the NCAP star ratings of the vehicles have improved over years, front occupant protection has improved as well; however, recent studies have shown that rear occupants are less protected in newer model years of vehicles [2]. Safety of rear occupants is not evaluated with the NCAP program. In this paper an attempt is made to verify whether the NCAP scores can show the level of protection provided to the rear occupants or not.
