Report: Automakers on Pace to Meet Standards
If recent trends continue, auto companies should be able to meet new federal fuel economy standards over the next 12 years, say University of Michigan researchers.
According to a report by Automotive Industries, a year after the U.S. Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) announced the final standard governing new-vehicle Corporate Average Fuel Economy (CAFE) for model years 2017-2025, CAFE performance has exceeded anticipated levels for 2012 and 2013 — the two years the current standard has been in effect.
Achieved CAFE performance levels exceeded the anticipated levels by 0.2 mpg for model year 2012 and 0.1 mpg for model year 2013. In addition, CAFE performance has consistently increased annually from model year 2008 through model year 2013, say Brandon Schoettle and Michael Sivak of the U-M Transportation Research Institute.
Overall, fuel economy improved by 4.3 mpg over these six model years, from 25.5 mpg to 29.8 mpg.
“If the current trends in annual improvements continue, future CAFE performance is expected to continue meeting or exceeding the projected performance levels— and desired greenhouse gas reductions—contained in the latest CAFE standards,” Schoettle said.
The new standard for fuel economy for vehicle model years 2017-2025 continues the current system of incremental increases in CAFE for new light-duty vehicles (cars, vans, SUVs and pickup trucks) for each model year, based on targeted decreases averaging about 5% per year in carbon dioxide output per mile. The strategy of simultaneously regulating fuel economy and greenhouse gas emissions of new vehicles was introduced in the current standard, in effect for model years 2012 through 2016.
These standards are projected to require average fleet-wide performance levels of 35.5 mpg by model year 2016 and 54.5 mpg by 2025.
“These performance levels assume that CAFE targets will be met purely through fuel economy improvements,” Schoettle said. “However, it is likely that manufacturers will also use alternative credits not related to improvements in fuel economy to assist in reaching these goals.”
