Federal Register / Vol. 86, No. 169 / Friday, September 3, 2021 / Proposed Rules E Permit expanded use of the automobile for cargo-carrying purposes or other non-passenger-carrying purposes through:
1 For non-passenger automobiles manufactured prior to model year 2012, the removal of seats to permit expanded use of the automobile for cargo-carrying purposes or other non-passengercarrying purposes through means provided by the automobiles manufacturer or with simple tools, such as screwdrivers and wrenches, so as to create a flat, floor level, surface extending from the forward-most point of installation of those seats to the rear of the automobiles interior; or 2 For non-passenger automobiles manufactured in model year 2008 and beyond, for vehicles equipped with at least 3 rows of designated seating positions as standard equipment, permit expanded use of the automobile for cargo-carrying purposes or other nonpassenger-carrying purposes through the removal or stowing of foldable or pivoting seats so as to create a flat, leveled cargo surface extending from the forward-most point of installation of those seats to the rear of the automobiles interior.
ii For an automobile capable of offhighway operation, identify which of the features below qualify the vehicle as off-road in accordance with 523.5b of this chapter and quantify the values of each feature:
A 4-wheel drive; or B A rating of more than 6,000
pounds gross vehicle weight; and C Has at least four of the following characteristics calculated when the automobile is at curb weight, on a level surface, with the front wheels parallel to the automobiles longitudinal centerline, and the tires inflated to the manufacturers recommended pressure.
The exact value of each feature should be quantified:
1 Approach angle of not less than 28
degrees.
2 Breakover angle of not less than 14
degrees.
3 Departure angle of not less than 20
degrees.
4 Running clearance of not less than 20 centimeters.
5 Front and rear axle clearances of not less than 18 centimeters each.
6 The fuel economy values provided under paragraphs c2 and 4 of this section shall be determined in accordance with 537.9.
7 Identify any air-conditioning AC, off-cycle, and full-size pick-up truck technologies used each model year to calculate the average fuel economy specified in 40 CFR 600.51012.

i Provide a list of each air conditioning efficiency improvement technology utilized in your fleets of vehicles for each model year. For each technology identify vehicles by make and model types that have the technology, which compliance category those vehicles belong to and the number of vehicles for each model equipped with the technology. For each compliance category domestic passenger car, import passenger car, and light truck, report the air conditioning fuel consumption improvement value in gallons/mile in accordance with the equation specified in 40 CFR 600.510
12c3i.
ii Provide a list of off-cycle efficiency improvement technologies utilized in your fleets of vehicles for each model year that is pending or approved by the EPA. For each technology identify vehicles by make and model types that have the technology, which compliance category those vehicles belong to, the number of vehicles for each model equipped with the technology, and the associated offcycle credits grams/mile available for each technology. For each compliance category domestic passenger car, import passenger car, and light truck, calculate the fleet off-cycle fuel consumption improvement value in gallons/mile in accordance with the equation specified in 40 CFR 600.510
12c3ii.
iii Provide a list of full-size pickup trucks in your fleet that meet the mild and strong hybrid vehicle definitions as specified in 40 CFR 86.180301. For each mild and strong hybrid type, identify vehicles by make and model types that have the technology, the number of vehicles produced for each model equipped with the technology, the total number of full-size pickup trucks produced with and without the technology, the calculated percentage of hybrid vehicles relative to the total number of vehicles produced, and the associated full-size pickup truck credits grams/mile available for each technology. For the light truck compliance category, calculate the fleet pickup truck fuel consumption improvement value in gallons/mile in accordance with the equation specified in 40 CFR 600.51012c3iii.

less than the applicable average fuel economy standard and who now projects an average fuel economy which is less than the applicable standard shall file a supplementary report containing the information specified in paragraph b1 of this section.
2 Except as provided in paragraph d of this section, each manufacturer that determines that its average fuel economy for the current model year as projected under 537.7b2 or, if no average fuel economy was projected under 537.7b2, as projected under 537.7b1, is less representative than the manufacturer previously reported it to be under 537.7b3, this section, or both, shall file a supplementary report containing the information specified in paragraph b2 of this section.
3 For model years through 2022, each manufacturer whose pre-model or mid-model year report omits any of the information specified in 537.7b or c shall file a supplementary report containing the information specified in paragraph b3 of this section.
4 Starting model year 2023, each manufacturer whose pre-model or midmodel year report omits any of the information shall resubmit the information with other information required in accordance with the NHTSA
CAFE Projections Reporting Template OMB Control No. 21270019, NHTSA
Form 1474.
b1 The supplementary report required by paragraph a1 of this section must contain:
i Such revisions of and additions to the information previously submitted by the manufacturer under this part regarding the automobiles whose projected average fuel economy has decreased as specified in paragraph a1 of this section as are necessary A To reflect the decrease and its cause; and B To indicate a new projected average fuel economy based upon these additional measures.
ii An explanation of the cause of the decrease in average fuel economy that led to the manufacturers having to submit the supplementary report required by paragraph a1 of this section.
2 The supplementary report required by paragraph a2 of this section must contain:
i A statement of the specific nature of and reason for the insufficiency in the representativeness of the projected average fuel economy;
ii A statement of specific additional testing or derivation of fuel economy values by analytical methods believed by the manufacturer necessary to eliminate the insufficiency; and
