AGENCY: National Highway Traffic

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

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 heavyduty pickup trucks and vans are 

available through model year 2027.

ACTION: Notice of public hearing. 

SUMMARY: The National Highway Traffic 

Safety Administration (NHTSA) is 

announcing a virtual public hearing to 

be held September 28, 2023, on its 

proposal for the ‘‘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,’’ which was signed on July 28, 

2023. This hearing also allows the 

public to provide oral comments 

regarding the Draft Environmental 

Impact Statement that accompanies the 

proposal. An additional session will be 

held on September 29, if necessary, to 

accommodate the number of people that 

sign up to testify. 

DATES: NHTSA will hold a virtual 

public hearing on September 28, 2023. 

An additional session will be held on 

September 29, if necessary, to 

accommodate the number of people that 

sign up to testify. The hearing will 

convene at 9 a.m. Eastern time and will 

conclude when the last pre-registered 

speaker has testified but no later than 6 

p.m. Eastern time. All hearing attendees, 

including those who do not intend to 

provide testimony, should preregister by 

September 22, 2023. Please refer to the 

SUPPLEMENTARY INFORMATION section for 

additional information on the public 

hearing. 

ADDRESSES: The link to register will be

SUPPLEMENTARY INFORMATION: NHTSA, 

on behalf of the DOT, is proposing new 

corporate average fuel economy (CAFE) 

standards for passenger cars and light 

trucks for MYs 2027–2032, and new fuel 

efficiency standards for heavy-duty 

pickup trucks and vans (HDPUVs) for 

MYs 2030–2035. This proposal 

responds to NHTSA’s statutory 

obligation to set CAFE and HDPUV 

standards at the maximum feasible level 

that the agency determines vehicle 

manufacturers can achieve in each MY, 

in order to improve energy 

conservation. Specifically, NHTSA is 

proposing new fuel economy standards 

for passenger cars and light trucks and 

fuel efficiency standards for model years 

(MYs) 2027–31 that increase at a rate of 

2 percent per year for passenger cars 

and 4 percent per year for light trucks, 

and new fuel efficiency standards for 

heavy-duty pickup trucks and vans 

(HDPUVs) for MYs 2030–2035 that 

increase at a rate of 10 percent per year. 

NHTSA is also setting forth proposed 

augural standards for MY 2032 

passenger cars and light trucks, which 

would increase at 2 percent and 4 

percent year over year, respectively, as 

compared to the prior year’s standards. 

In addition, NHTSA is also proposing 

certain technical amendments to clarify 

and streamline our compliance 

regulations. The proposal was signed on 

July 28, 2023, and was published in the 

Federal Register on August 17, 2023. A 

notice of availability for the 

accompanying Draft Environmental 

Impact Statement (Draft EIS) was 

published in the Federal Register on 

August 04, 2023 (88 FR 51812). The 

Draft EIS is available on NHTSA’s CAFE 

website, https://www.nhtsa.gov/cafe, 

and is also available in Docket ID No.
