Automaker’s attempts to bring down their company-wide fuel economy ratings in line with the standards set by the National Highway Traffic Safety Administration (NHTSA) in the USA are ahead of projected targets three years into the program.

A newly released report by the University of Michigan Trasportation Research Institute titled “A comparison of CAFE standards and actual CAFE performance of new light-duty vehicles: An update through model year 2014” found that CAFE performance has exceeded the projected achievements set out by the standards in every year since its implication.

The Corporate Average Fuel Economy standards can be achieved through both vehicle ratings as measured by the EPA, and other trade offs and credits earned through manufacturing processes and other corporate initiatives.

As explained by Brandon Schoettle, a project manager at the University of Michigan Transportation Research Institute, the report looked at measures of fuel economy only, “The “projection” and “actual” can be compared because they are both measures of vehicle fuel economy only.”

“However, the “target” values include any credits that might also be used by each automaker. The credits supplement the fuel economy performance to get the “final” CAFE values – something we did not include in the report.”
