A Critique of the National Research Council Study of the Potential for Improving Automobile Fuel Economy

Research Report T924


John DeCicco


A 1992 NRC study concluded that only modest improvements in new car fuel economy would be possible over the next 15 years. This critique points out technological options that were either omitted or downplayed in the NRC study as well as weaknesses in the economic market and policy analyses. It explains why the NRC study fell short of identifying the opportunities for and benefits of fuel economy improvements documented in ACEEE reports T932, T912 and E913.
