A Comparison of CAFE Standards and Actual CAFE Performance of New Light-Duty Vehicles, an October 3 report by the University of Michigan Transportation Research Institute, found that average vehicle fuel economy has risen 4.3 miles per gallon since 2008. Model year 2013 light-duty vehicles’ average fuel economy is 29.8 mpg, exceeding the 29.7 mpg requirement set by the standards. The report said the CAFE performance will continue to be met or exceeded if improvement trends continue.
