Structural Options for Phase 2 Heavy-Duty Vehicle Fuel Efficiency and Greenhouse Gas Standards
In the first standards for greenhouse gas (GHG) emissions and fuel efficiency for model years 2014-2019 heavy-duty vehicles, the Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) set separate standards for engines and the rest of the vehicle. This document looks at the feasibility of applying standards to the whole vehicle. Six criteria are explored as they relate to maintaining the current separate approach or using a full-vehicle standard. The criteria are: low-cost testing, reflection of real-world performance, reasonable compliance and enforcement, compliance flexibility, promotion of advanced technologies, and compatibility with criteria emission testing. The authors suggest two additional standards options: integrated engine plus transmission standards and a combined approach including engine testing and full-vehicle testing. The authors recommend replacing the engine standard with an engine plus transmission standard and combining this with a full-vehicle standard.
