C-NCAP has evaluated over 300 vehicle types in the past 10 years. The 2018 version of C-NCAP introduces adjustments to test protocols and evaluation methods, including changes to the chest index evaluation, whiplash test speed, and rating system. It also adds new tests for pedestrian protection and autonomous emergency braking (AEB) systems. Scoring requirements will become more stringent over time, with the minimum score needed for a 5-star rating increasing from 75% in 2018 to 85% by 2020.
