B

Statement of Task

  1. The committee will review the NHTSA fuel consumption regulations promulgated on 15 September 2011 (76 Federal Register 57106) and consider the technological, market and regulatory factors that may be of relevance to a revised and updated regulatory regime taking effect for model years 2019-2022. This review will include, but not be limited to, the potential for technological change in commercial vehicles in MY 2019-2022 and the impact it might have on the regulatory regime. Also as part of its review, the committee will explore regulatory options for trailers.
  2. The committee will analyze and provide options for improvements to the certification and compliance procedures for medium- and heavy-duty vehicles—including the use of representative test cycles and simulation using various models—such as might be implemented in revised fuel consumption regulations affecting MY 2019-2022.
  3. The committee will review an updated analysis of the makeup and characterization of the medium- and heavy-duty truck fleet, including combination tractors, trailers, busses and vocational vehicles. The committee also will review the methodology for providing on-road information on fuel consumption.
  4. The committee will examine the barriers to and the potential applications of natural gas in class 2b through class 8 vehicles. The committee will consider how such vehicles could be included in the framework on fuel consumption regulations.
  5. The committee will address uncertainties and perform sensitivity analyses for the fuel consumption and cost/ benefit estimates, to the extent possible, and provide guidance to NHTSA on improving its uncertainty analyses given the relatively long time frame for these future estimates.

Medium- and heavy-duty trucks, motor coaches, and transit buses - collectively, "medium- and heavy-duty vehicles", or MHDVs - are used in every sector of the economy. The fuel consumption and greenhouse gas emissions of MHDVs have become a focus of legislative and regulatory action in the past few years. Reducing the Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles, Phase Two is a follow-on to the National Research Council's 2010 report, Technologies and Approaches to Reducing the Fuel Consumption of Medium-and Heavy-Duty Vehicles. That report provided a series of findings and recommendations on the development of regulations for reducing fuel consumption of MHDVs.

This report comprises the first periodic, five-year follow-on to the 2010 report. Reducing the Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles, Phase Two reviews NHTSA fuel consumption regulations and considers the technological, market and regulatory factors that may be of relevance to a revised and updated regulatory regime taking effect for model years 2019-2022. The report analyzes and provides options for improvements to the certification and compliance procedures for medium- and heavy-duty vehicles; reviews an updated analysis of the makeup and characterization of the medium- and heavy-duty truck fleet; examines the barriers to and the potential applications of natural gas in class 2b through class 8 vehicles; and addresses uncertainties and performs sensitivity analyses for the fuel consumption and cost/benefit estimates.
