91 domestic vehicles have been tested according to Korean New Car Assessment frontal crashworthiness test protocol, and 52 out of the 91 vehicles are rated 5 star, which means the highest frontal crashworthiness. Only 12.5% of the test vehicles were rated 5 star before 2002 while 73.1% of the test vehicles were rated 5 star since 2003. The portion of 5 star rated vehicles are increased by 6 times during the last ten years. Even though vehicle frontal crashworthiness improved, the deaths in frontal crash impact do not decreased. In 2012, 329 occupants were died in frontal crash, this is 17.1% decreased compare to that of 2002, but the deaths in frontal crash occupies about 15.7% of the vehicle to vehicle deaths and this is 1.3%P higher than that of 2002. This figures show that the KNCAP frontal crashworthiness test protocol does not enough to reflect the real world frontal crash accident. In this study we conducted small overlap frontal crash according to IIHS test protocol, which occupies high portion of deaths in frontal crash, to evaluate vehicle frontal crashworthiness.
