NHTSA has carried out a lot of New US NCAP test became effective from MY2011. Injury probability of New US NCAP test is more severe than previous NCAP test. The Hybrid Ⅲ 5<SUP>th</SUP> %ile dummy in front passenger position is used instead of 50<SUP>th</SUP> %ile dummy. 5<SUP>th</SUP> %ile dummy gets lower points than 50<SUP>th</SUP> %ile dummy in most tests. One of the main cause is Nij. Especially neck extension moment value is main factor to improve Nij. US NCAP frontal test data was review to know tendency of neck extension moment value. The object of the study is to find out how extension moment occur and what is the correlationship with other sensor. Furthermore, sled test is conducted to analyze extension moment based on analysis result.
