In 2015 Euro NCAP updated its test protocols and in 2016 Euro NCAP updated its assessment protocol. The aim of this was to advance the vehicle restraint systems in the second seat row for both small adults and children. This included the introduction of a full width frontal test and modification to the existing offset frontal and side impact tests.

The update to the protocols aimed to enhance the vehicle restraint systems towards a more efficient one, including belt load limiters and belt pretensioners. As far as child occupant protection is concerned the objective of Euro NCAP was to seek a combined restraint strategy allowing both the vehicle restraint system and the child restraint system (CRS) to work together. The child restraint systems used for the crash testing are a highback booster for the Q6 and a booster cushion for the Q10.

The aim of this study was to investigate the performance of the vehicles tested with regards to the three key areas covered by the protocol:​ i.e. CRS installation checks, safety provisions in the vehicle and crash performance. The test results from 97 vehicles tested by Euro NCAP between January 2016 and December 2018 were analysed. Where possible the reasons for differences between the best and worst performers for each assessment were investigated.
