Department of Transportation, National Highway Traffic Safety Administration: Average Fuel Economy Standards Passenger Cars and Light Trucks Model Year 2011
GAO-09-592R: Apr 15, 2009
GAO reviewed the Department of Transportation (DOT), National Highway Traffic Safety Administration's new rule on average fuel economy standards for passenger cars and light trucks for model year 2011. GAO found that (1) the final rule sets the final fuel economy standards for Model Year 2011 passenger cars and light trucks. Under the final rule, if each manufacturer produced its expected mix of automobiles and just met its obligations under the "optimized" standards, the combined industry-wide average fuel economy for MY 2011 passenger cars would be 30.2 mpg and for MY 2011 light trucks it would be 24.1 mpg. The final rule creates an alternative minimum standard for domestic passenger cars of 27.8 mpg. The final rule also adopts a new regulation on credits earned for exceeding applicable CAFE standards; and (2) DOT complied with applicable requirements in promulgating the rule.
