Abstract Pedestrian impact testing of the U.S. vehicle fleet by the National Highway Traffic Safety Administration has provided snapshots of the performance of evolving technologies that protect a pedestrian’s head in head-to-hood impacts. One of the recent evolving technologies is the introduction of active hood systems that pop up upon contact with a pedestrian to provide a more “cushioned” impact. Two vehicle models, a 2014 Cadillac ATS and a 2017 Audi A4, were tested with and without an active hood system to examine how active hoods affect pedestrian safety in headform impacts. The effects of the active hood systems were found to vary for both vehicles. For the Cadillac ATS, the active hood had a significant influence as HIC values went from high with the undeployed hood to very low with the active system. For the Audi A4, the undeployed hood produced low-to-moderately high HIC scores with negligible improvement with the active system.
