| 49:49:6.1.2.3.13.0.1.6 | 49 | Transportation | V | 531 | PART 531—PASSENGER AUTOMOBILE AVERAGE FUEL ECONOMY STANDARDS | § 531.6 Measurement and calculation procedures. | NHTSA | [87 FR 26070, May 2, 2022, as amended at 89 FR 52948, June 24, 2024] | (a) The fleet average fuel economy performance of all passenger automobiles that are manufactured by a manufacturer in a model year shall be determined in accordance with procedures established by the Administrator of the Environmental Protection Agency (EPA) under 49 U.S.C. 32904 and set forth in 40 CFR part 600. (b) For model years 2017 through 2031, a manufacturer is eligible to increase the fuel economy performance of passenger cars in accordance with procedures established by the Environmental Protection Agency (EPA) set forth in 40 CFR part 600, subpart F, including adjustments to fuel economy for fuel consumption improvements related to air conditioning (AC) efficiency and off-cycle technologies. Starting in model year 2027, fuel economy increases for fuel consumption improvement values under 40 CFR 86.1868-12 and 40 CFR 86.1869-12 only apply for vehicles propelled by internal combustion engines. Manufacturers must provide reporting on these technologies as specified in § 537.7 of this chapter by the required deadlines. (1) Efficient AC technologies. A manufacturer may increase its fleet average fuel economy performance through the use of technologies that improve the efficiency of AC systems pursuant to the requirements in 40 CFR 86.1868-12. Fuel consumption improvement values resulting from the use of those AC systems must be determined in accordance with 40 CFR 600.510-12(c)(3)(i). (2) Off-cycle technologies on EPA's predefined list. A manufacturer may increase its fleet average fuel economy performance through the use of off-cycle technologies pursuant to the requirements in 40 CFR 86.1869-12 for predefined off-cycle technologies in accordance with 40 CFR 86.1869-12(b). The fuel consumption improvement is determined in accordance with 40 CFR 600.510-12(c)(3)(ii). (3) Off-cycle technologies using 5-cycle testing. Through model year 2026, a manufacturer may increase its fleet average fuel economy performance through the use of off-cycle technologies tested using the EPA's 5-cycle methodology in… |
