Corporate Average Fuel Economy Standards for Passenger Cars and
Light Trucks for Model Years 2027-2032 and Fuel Efficiency Standards
for Heavy-Duty Pickup Trucks and Vans for Model Years 2030-2035;
Correction
AGENCY: National Highway Traffic Safety Administration (NHTSA).
ACTION: Notice of proposed rulemaking; correction.
-----------------------------------------------------------------------
SUMMARY: This document corrects technical errors in the proposed rule
that appeared in the Federal Register on August 17, 2023, entitled
``Corporate Average Fuel Economy Standards for Passenger Cars and Light
Trucks for Model Years 2027-2032 and Fuel Efficiency Standards for
Heavy-Duty Pickup Trucks and Vans for Model Years 2030-2035.'' That
document proposed new Corporate Average Fuel Economy (CAFE) standards
for passenger cars and light trucks to be manufactured in model years
(MYs) 2027-2032, and new fuel efficiency standards for heavy-duty
pickup trucks and vans (HDPUVs) to be manufactured in MYs 2030-2035.
DATES: Comments for the proposed rule published on August 17, 2023, at
88 FR 56128, must be received on or before October 16, 2023.
FOR FURTHER INFORMATION CONTACT: Joseph Bayer, CAFE Program Division
Chief, Office of Rulemaking, National Highway Traffic Safety
Administration, 1200 New Jersey Avenue SE, Washington, DC 20590; email:
joseph.bayer@dot.gov; phone: (202) 366-9540.
SUPPLEMENTARY INFORMATION: Prior to publication of the proposal for new
CAFE standards for passenger cars and light trucks and new fuel
efficiency standards for HDPUVs, NHTSA noticed several minor
typographical errors that could not be corrected prior to printing. The
needed corrections to the preamble replace the target function
coefficient numbers in Table II-3, Table III-4, Table III-12, Table
III-13, Table III-15, Table III-16, Table III-18, Table III-19, Table
III-21, and Table III-22. NHTSA notes that these modifications do not
change the values but simply provide additional significant figures for
the coefficients. For the reader's reference, NHTSA has also made the
corresponding changes to the target coefficient tables in the
accompanying Technical Support Document (TSD) and Preliminary
Regulatory Impact Assessment (PRIA), which are found in the docket for
this rulemaking and on the agency's website. The needed correction to
the proposed regulatory text clarifies that NHTSA is proposing to
eliminate 5-cycle and alternative approvals for off-cycle fuel
consumption incentive values (FCIVs) starting in MY 2027. This document
also corrects the proposed regulatory text to clarify that multipliers
for advanced, innovative, and off-cycle technologies for heavy-duty
pickup trucks and vans are available through model year 2027.

issue of August 17, 2023, make the following corrections, in the
Regulatory Text section.

1. On page 56385, column 1, in Sec. 531.6, correct paragraph (b)(3)
and paragraph (b)(4) introductory text to read as follows:
Sec. 531.6 [Corrected]
* * * * *
(b) * * *
(3) Off-cycle technologies using 5-cycle testing. Through MY 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 accordance with 40 CFR 86.1869-12(c). The fuel
consumption improvement is determined in accordance with 40 CFR
600.510-12(c)(3)(ii).
(4) Off-cycle technologies using the alternative EPA-approved
methodology. Through MY 2026, a manufacturer may seek to increase its
fuel economy performance through use of an off-cycle technology
requiring an application request made to the EPA in accordance with 40
CFR 86.1869-12(d).

(9) Advanced, innovative and off-cycle technologies. For vehicles
subject to Phase 1 standards, manufacturers may generate separate
credit allowances for advanced and innovative technologies as specified
in Sec. 535.7(f)(1) and (2). For vehicles subject to Phase 2
standards, manufacturers may generate separate credits allowance for
off-cycle technologies in accordance with Sec. 535.7(f)(2). Separate
credit allowances for advanced technology vehicles cannot be generated;
instead, manufacturers may use the credit multipliers specified in
Sec. 535.7(f)(1)(ii) through model year 2027.
