§32906 — Title 49 Transportation | U.S. Code

Summary

Limits how much a maker’s average fuel economy can go up because of dual‑fuel cars. For model years 1993–2014 the cap is 1.2 miles per gallon; 2015 is 1.0 mpg; 2016 is 0.8 mpg; 2017 is 0.6 mpg; 2018 is 0.4 mpg; 2019 is 0.2 mpg; and after 2019 the cap is 0 mpg. This does not apply to electric cars or, starting in 2016, certain other alternative‑fuel cars. The EPA must calculate the increase by taking the maker’s reported average fuel economy and subtracting the average the maker would have had if dual‑fuel cars were counted using their gasoline or diesel fuel economy.

(a)For each of model years 1993 through 2019 for each category of automobile (except an electric automobile or, beginning with model year 2016, an alternative fueled automobile that uses a fuel described in subparagraph (E) of section 32901(a)(1)), the maximum increase in average fuel economy for a manufacturer attributable to dual fueled automobiles is—

(1)1.2 miles a gallon for each of model years 1993 through 2014;

(2)1.0 miles per gallon for model year 2015;

(3)0.8 miles per gallon for model year 2016;

(4)0.6 miles per gallon for model year 2017;

(5)0.4 miles per gallon for model year 2018;

(6)0.2 miles per gallon for model year 2019; and

(7)0 miles per gallon for model years after 2019.

(b)In applying subsection (a), the Administrator of the Environmental Protection Agency shall determine the increase in a manufacturer’s average fuel economy attributable to dual fueled automobiles by subtracting from the manufacturer’s average fuel economy calculated under section 32905(f) the number equal to what the manufacturer’s average fuel economy would be if it were calculated by the formula under section 32904(a)(1) by including as the denominator for each model of dual fueled automobiles the fuel economy when the automobiles are operated on gasoline or diesel fuel.
