NHTSA Hosts Vehicle Mass-Size-Safety Workshop (05/2013)
NHTSA conducted a workshop on May 13-14, 2013, on issues related to fuel economy, vehicle mass reduction and the effects of vehicle mass and size on vehicle safety.The purpose of the workshop was to bring together experts in the field to discuss questions that NHTSA must grapple with when we establish CAFE standards for model years 2022-2025 – like how much mass reduction will be feasible for different vehicles, how much that mass reduction will cost, and whether there will be safety effects as a result of that mass reduction.
NHTSA researchers, along with other government researchers, auto manufacturers and supplier representatives, and other experts, presented latest findings on these questions, solicited public feedback, and discussed future projects.
