Propulsion technology and regulation are rapidly evolving—yet propulsion suppliers do not necessarily have the resources to adequately monitor this changing landscape. CAR facilitates an open discussion via regular roundtable meetings of our propulsion working group focused on non-proprietary and non-competitive topics as they pertain to understanding fuel economy and emissions regulations, identifying gaps and opportunities in the future of propulsion technologies, Alternative Fuels, Policy (emissions, fuel economy, GHG), and better understanding propulsion pathways and how customers will react to current and future regulations.
