... These developments will impact automaker options for vehicle efficiency and bring about changes to consumer behavior and vehicle system services, including dealerships, vehicle service and repair, fueling and charging infrastructure, and transportation planning. This report of the National Academies of Sciences, Engineering, and Medicine Committee on Assessment of Technologies for Improving Fuel Economy of Light-Duty Vehicles -- Phase 3 addresses the potential for internal combustion engine, hybrid, battery electric, fuel cell, non-powertrain, and connected and automated vehicle technologies to contribute to efficiency in 2025–2035.
From page 2...
... BATTERY AND FUEL CELL ELECTRIC VEHICLES Automakers have developed electrified powertrain systems with zero or ultra-low tailpipe emissions. Many automakers have sold BEVs and plug-in hybrid electric vehicles (PHEVs)
From page 3...
... the potential changes in mass disparity that could occur in a fleet with increased penetration of electric vehicles, ADAS, CUVs, SUVs, and pickup trucks. Furthermore, the Federal Motor Vehicle Safety Standards for crashworthiness should consider crash compatibility with emphasis on differences in vehicle mass and design.
From page 4...
... NHTSA should consider regulating fuel efficiency of autonomous vehicles for fleet use more stringently than personally owned vehicles; an all-electric requirement should be considered, at least for urban areas. ENERGY AND EMISSIONS IMPACTS OF NON-PETROLEUM FUELS In 2025–2035, emerging alternative fuels, such as electricity, hydrogen, and low-carbon synthetic fuels, are expected to see increasing use in the light-duty fleet.
From page 5...
... REGULATORY STRUCTURE AND FLEXIBILITIES Vehicle fuel economy regulation began under the Energy Policy and Conservation Act of 1975, with the most recent regulation being the 2020 Safer Affordable Fuel Efficient Vehicles Rule.
From page 6...
... The EPA can and must consider the availability and benefits of ZEVs and more efficient petroleum-fueled vehicles in setting the most stringent feasible GHG emission standards. In order to remain binding and relevant, NHTSA's program must consider the fuel economy or energy efficiency benefits provided by alternative fuel vehicles such as battery electric vehicles and fuel cell electric vehicles in setting the stringency of its corporate average fuel economy standards, either by NHTSA's interpretation of existing statute or by Congress passing a new or amended statute.
From page 7...
... The National Highway Traffic Safety Administration should study mass dis parity in 2025–2035, improve federal motor vehicle safety standards testing protocols for crash compat ibility, and further develop testing or computer-aided engineering fleet modeling to simulate real-world crash interactions between new vehicle designs and with vulnerable users at different impact speeds and impact configurations.

... SUMMARY RECOMMENDATION 16. Car and Truck Standards: The National Highway Traffic Safety Administration and the U.S.
From page 9...
... RECOMMENDATION 13.3: Congress should reauthorize the continuation of the National Highway Traffic Safety Administration (NHTSA) corporate average fuel economy (CAFE)
