0.1 represents the time in seconds between each successive velocity
data point;
0.44704 converts speed from miles/hour to meters/second;
2.205 converts weight from pounds to kilograms; and
1,000 converts power from Watts to kilowatts.

    (C) Determine braking power in kilowatts using the following
equation. Note that during braking events, Pbrake,
Paccel, and Proadload will all be negative (i.e.,
resistive) forces on the vehicle.

Where:

 Paccel = the value determined in paragraph (c)(1)(i)(B)
of this section;
Proadload = the value determined in paragraph
(c)(1)(i)(A) of this section; and
Pbrake = 0 if Paccel is greater than or equal
to Proadload.

    (ii) The total maximum braking energy (Ebrake) that
could theoretically be recovered is equal to the absolute value of the
sum of all the values of Pbrake determined in paragraph
(c)(1)(i)(C) of this section, divided by 36000 (to convert 10 Hz data
to hours) and

rounded to the nearest 0.01 kilowatt hours.
    (2) Calculate the actual amount of energy recovered
(Erec) by a hybrid electric vehicle when tested on the FTP
according to the provisions of this part, as follows:
    (i) Measure the electrical current in Amps to and from the hybrid
electric vehicle battery during the FTP. Measurements should be made
directly upstream of the battery at a 10 Hz sampling rate.
    (ii) At each sampling point where current is flowing into the
battery, calculate the current flowing into the battery, in Watt-hours,
as follows:
[GRAPHIC] [TIFF OMITTED] TR15OC12.059

Where:

Et = the current flowing into the battery, in Watt-hours,
at time t in the test;
It = the electrical current, in Amps, at time t in the
test; and
Vnominal = the nominal voltage of the hybrid battery
system determined according to paragraph (c)(4) of this section.

    (iii) The total energy recovered (Erec) is the absolute
value of the sum of all values of Et that represent current
flowing into the battery, divided by 1000 (to convert Watt-hours to
kilowatt-hours).
    (3) The percent of braking energy recovered by a hybrid system
relative to the total available energy is determined by the following
equation, rounded to the nearest one percent:
[GRAPHIC] [TIFF OMITTED] TR15OC12.060

Where:

Erec = The actual total energy recovered, in kilowatt
hours, as determined in paragraph (c)(2) of this section; and
Ebrake = The theoretical maximum amount of energy, in
kilowatt hours, that could be recovered by a hybrid electric vehicle
over the FTP test cycle, as determined in paragraph (c)(1) of this
section.

    (4)(i) Determination nominal voltage (Vnominal) using
the following equation:
[GRAPHIC] [TIFF OMITTED] TR15OC12.061

Where:

VS is the battery voltage measured at the start of the
FTP test, where the measurement is made after the key-on event but
not later than 10 seconds after the key-on event; and
VF is the battery voltage measured at the conclusion of
the FTP test, where the measurement is made before the key-off event
but not earlier than 10 seconds prior to the key-off event.

    (ii) If the absolute value of the measured current to and from the
battery during the measurement of either VS or VF
exceeds three percent of the maximum absolute value of the current
measured over the FTP, then that VS or VF value
is not valid. If no valid voltage measurement can be made using this
method, the manufacturer must develop an alternative method of
determining nominal voltage. The alternative must be developed using
good engineering judgment and is subject to EPA approval.

30. Section 600.210-12 is amended by revising paragraphs (a)
introductory text and (a)(5) to read as follows:

Sec.  600.210-12  Calculation of fuel economy and CO2 emission values
for labeling.

    (a) General labels. Except as specified in paragraphs (d) and (e)
of this section, fuel economy and CO2 emissions for general
labels may be determined by one of two methods. The first is based on
vehicle-specific model-type 5-cycle data as determined in Sec.
600.209-12(b). This method is available for all vehicles and is
required for vehicles that do not qualify for the second method as
described in Sec.  600.115 (other than electric vehicles). The second
method, the derived 5-cycle method, determines fuel economy and
CO2 emissions values from the FTP and HFET tests using
equations that are derived from vehicle-specific 5-cycle model type
data, as determined in paragraph (a)(2) of this section. Manufacturers
may voluntarily lower fuel economy values and raise CO2
values if they determine that the label values from any method are not
representative of the fuel economy and CO2 emissions for
that model type. MPG values may not be lowered without also making a
corresponding change to the CO2 value for a model type.
* * * * *
    (5) General alternate fuel economy and CO2 emissions
label values for fuel cell vehicles. Determine FTP-based city and HFET-
based highway fuel economy label values for fuel cell vehicles using
procedures specified by the Administrator. Convert kilograms of
hydrogen/mile results to miles per kilogram of hydrogen and miles per
gasoline gallon equivalent. CO2 label information is based
on tailpipe emissions only, so CO2 emissions from fuel cell
vehicles are assumed to be zero.

    (c) You may include the sub-heading ``Driving Range'' below the
combined fuel economy value, with range bars below this sub-heading as
follows:
    (1) Insert a horizontal range bar nominally 80 mm long to show how
far the vehicle can drive from a full tank of gasoline. Include a
vehicle logo at the right end of the range bar. Include the following
left-justified expression inside

the range bar: ``Gasoline: x miles''. Complete the expression by
identifying the appropriate value for total driving range from Sec.
600.311.
    (2) Insert a second horizontal range bar as described in paragraph
(c)(1) of this section that shows how far the vehicle can drive from a
full tank with the second fuel. Establish the length of the line based
on the proportion of driving ranges for the different fuels. Identify
the appropriate fuel in the range bar.

    (i) For model years 2012 through 2015, and for each category of
automobile identified in paragraph (a)(1) of this section, the maximum
decrease in average carbon-related exhaust emissions determined in
paragraph (j) of this section attributable to alcohol dual fuel
automobiles and natural gas dual fuel automobiles shall be calculated
using the following formula, and rounded to the nearest tenth of a gram
per mile:
[GRAPHIC] [TIFF OMITTED] TR15OC12.068

Where:

FltAvg = The fleet average CREE value in grams per mile, rounded to
the nearest whole number, for passenger automobiles or light trucks
determined for the applicable model year according to paragraph (j)
of this section, except by assuming all alcohol dual fuel and
natural gas dual fuel automobiles are operated exclusively on
gasoline (or diesel) fuel. For the purposes of these calculations,
the values for natural gas dual fuel automobiles using the optional
Utility Factor approach in paragraph (j)(2)(vii) of this section
shall not be the gasoline CREE values, but the CREE values
determined in paragraph (j)(2)(vii) of this section.
MPGMAX = The maximum increase in miles per gallon
determined for the

appropriate model year in paragraph (h) of this section.

    (1) The Administrator shall calculate the decrease in average
carbon-related exhaust emissions to determine if the maximum decrease
provided in this paragraph (i) has been reached. The Administrator
shall calculate the average carbon-related exhaust emissions for each
category of automobiles specified in paragraph (a) of this section by
subtracting the average carbon-related exhaust emission values
determined in paragraph (j) of this section from the average carbon-
related exhaust emission values calculated in accordance with this
section by assuming all alcohol dual fuel and natural gas dual fuel
automobiles are operated exclusively on gasoline (or diesel) fuel. For
the purposes of these calculations, the values for natural gas dual
fuel automobiles using the optional Utility Factor approach in
paragraph (j)(2)(vii) of this section shall not be the gasoline CREE
values, but the CREE values determined in paragraph (j)(2)(vii) of this
section. The difference is limited to the maximum decrease specified in
paragraph (i) of this section.

standing and a line tangent to the front tire static loaded radius arc
and touching the underside of the automobile forward of the front tire.
    Axle clearance means the vertical distance from the level surface
on which an automobile is standing to the lowest

point on the axle differential of the automobile.
    Base tire (for passenger automobiles, light trucks, and medium duty
passenger vehicles) means the tire size specified as standard equipment
by the manufacturer on each unique combination of a vehicle's footprint
and model type. Standard equipment is defined in 40 CFR 86.1803-01.

    Breakover angle means the supplement of the largest angle, in a
plan side view of an automobile, that can be formed by two lines
tangent to the front and rear static loaded radii arcs and intersecting
at a point on the underside of the automobile.
    Cab-complete vehicle means a vehicle that is first sold as an
incomplete vehicle that substantially includes the vehicle cab section
as defined in 40 CFR 1037.801. For example, vehicles known commercially
as chassis-cabs, cab-chassis, box-deletes, bed-deletes, and cut-away
vans are considered cab-complete vehicles. A cab includes a steering
column and a passenger compartment. Note that a vehicle lacking some
components of the cab is a cab-complete vehicle if it substantially
includes the cab.
    Cargo-carrying volume means the luggage capacity or cargo volume
index, as appropriate, and as those terms are defined in 40 CFR
600.315-08, in the case of automobiles to which either of these terms
apply. With respect to automobiles to which neither of these terms
apply, ``cargo-carrying volume'' means the total volume in cubic feet,
rounded to the nearest 0.1 cubic feet, of either an automobile's
enclosed non-seating space that is intended primarily for carrying
cargo and is not accessible from the passenger compartment, or the
space intended primarily for carrying cargo bounded in the front by a
vertical plane that is perpendicular to the longitudinal centerline of
the automobile and passes through the rearmost point on the rearmost
seat and elsewhere by the automobile's interior surfaces.

this definition, ``track width'' is the lateral distance between the
centerlines of the base tires at ground, including the camber angle.
For purposes of this definition, ``wheelbase'' is the longitudinal
distance between front and rear wheel centerlines.
    Full-size pickup truck has the meaning given in 40 CFR 86.1803-01.

manufacturer could reasonably expect to be used for) motive power in a
heavy-duty vehicle. For purposes of this definition in this part, the
term ``engine'' includes internal combustion engines and other devices
that convert chemical fuel into motive power. For example, a fuel cell
and motor used in a heavy-duty vehicle is a heavy-duty engine.
    Heavy-duty off-road vehicle means a heavy-duty vocational vehicle
or vocational tractor that is intended for off-road use meeting either
of the following criteria:
    (1) Vehicles with tires installed having a maximum speed rating at
or below 55 mph.

    Innovative technology means technology certified as such under 40
CFR 1037.610.
    Light truck means a non-passenger automobile as defined in Sec.
523.5.
    Medium duty passenger vehicle means a vehicle which would satisfy
the criteria in Sec.  523.5 (relating to light trucks) but for its
gross vehicle weight rating or its curb weight, which is rated at more
than 8,500 lbs GVWR or has a vehicle curb weight of more than 6,000 lbs
or has a basic vehicle frontal area in excess of 45 square feet, and

the standards set forth in paragraphs (c) and (d) in this section, if
NHTSA determines in a rulemaking, initiated after January 1, 2017, and
conducted in accordance with 49 U.S.C. 32902, that the standards in
paragraphs (c) and (d) are the maximum feasible standards for model
years 2022-2025. If, for any of those model years, NHTSA determines
that the maximum feasible standard for passenger cars and the
corresponding minimum standard for domestically manufactured passenger
cars should be set at a different level, manufacturers shall comply
with those different standards in lieu of the standards set forth for
those model years in paragraphs (c) and (d), and NHTSA will revise this
section to reflect the different standards.

39. Revise Sec.  531.6 to read as follows:

Sec.  531.6  Measurement and calculation procedures.

    (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 under 49 U.S.C.
32904 and set forth in 40 CFR part 600. For model years 2017 to 2025, a
manufacturer is eligible to increase the fuel economy performance of
passenger cars in accordance with procedures established by EPA set
forth in 40 CFR part 600, including any adjustments to fuel economy EPA
allows, such as for fuel consumption improvements related to air
conditioning efficiency and off-cycle technologies.
    (b) The eligibility of a manufacturer to increase its fuel economy
performance through use of an off-cycle technology requires an
application request made to EPA in accordance with 40 CFR Part 86.1869-
12 and an approval granted by EPA made in consultation with NHTSA. In
order to expedite NHTSA's consultation with EPA, a manufacturer's
application as part of the off-cycle credit approval process under 40
CFR 86.1869-12(b) or 40 CFR 86.1869-12(c) shall also be submitted to
NHTSA at the same time if the manufacturer is seeking off-cycle fuel
economy improvement values under the CAFE program for those
technologies. For off-cycle technologies which are covered under 40 CFR
86.1869-12(b) or 40 CFR 86.1869-12(c), NHTSA will consult with EPA
regarding NHTSA's evaluation of the specific off-cycle technology to
ensure its impact on fuel economy and the suitability of using the off-
cycle technology to adjust the fuel economy performance. NHTSA will
provide its views on the suitability of the technology for that purpose
to EPA. NHTSA's evaluation and review will consider:
    (1) Whether the technology has a direct impact upon improving fuel
economy performance;
    (2) Whether the technology is related to crash-avoidance
technologies, safety critical systems or systems affecting safety-
critical functions, or technologies designed for the purpose of
reducing the frequency of vehicle crashes;
    (3) Information from any assessments conducted by EPA related to
the application, the technology and/or related technologies; and
    (4) Any other relevant factors.

    (f) For each model year 1996 and thereafter, each manufacturer
shall combine its captive imports with its other light trucks and
comply with the fleet average fuel economy standard in paragraph (a) of
this section.
    (g) For model years 2008-2010, at a manufacturer's option, a
manufacturer's light truck fleet may comply with the fuel economy
standard calculated for each model year according to Figure 1 and the
appropriate values in Table V, with said option being irrevocably
chosen for that model year and reported as specified in Sec.  537.8.
    (h) For model year 2011, a manufacturer's light truck fleet shall
comply with the fleet average fuel economy standard calculated for that
model year according to Figure 1 and the appropriate values in Table V.
    (i) For model years 2012-2016, a manufacturer's light truck fleet
shall comply with the fleet average fuel economy standard calculated
for that model year according to Figures 2 and 3 and the appropriate
values in Table VI.
    (j) For model years 2017-2025, a manufacturer's light truck fleet
shall comply with the fleet average fuel economy standard calculated
for that model year according to Figures 2 and 4 and the appropriate
values in Table VII.
    (k) For model years 2022-2025, each manufacturer shall comply with
the standards set forth in paragraph (j) in this section, if NHTSA
determines in a rulemaking, initiated after January 1, 2017, and
conducted in accordance with 49 U.S.C. 32902, that the standards in
paragraph (j) are the maximum feasible standards for model years 2022-
2025. If, for any of those model years, NHTSA determines that the
maximum feasible standard for light trucks should be set at a different
level, manufacturers shall comply with those different standards in
lieu of the standards set forth for those model years in paragraph (j),
and NHTSA will revise this section to reflect the different standards.

Sec.  533.6  Measurement and calculation procedures.

* * * * *
    (b) The fleet average fuel economy performance of all vehicles
subject to Part 533 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 under 49
U.S.C. 32904 and set forth in 40 CFR part 600. For model years 2017 to
2025, a manufacturer is eligible to increase the fuel economy
performance of light trucks in accordance with procedures established
by EPA set forth in 40 CFR part 600, including any adjustments to fuel
economy EPA allows, such as for fuel consumption improvements related

to air conditioning efficiency, off-cycle technologies, and
hybridization and other performance-based technologies for full-size
pickup trucks.
    (c) The eligibility of a manufacturer to increase its fuel economy
performance through use of an off-cycle technology requires an
application request made to EPA in accordance with 40 CFR Part 86.1869-
12 and an approval granted by EPA made in consultation with NHTSA. In
order to expedite NHTSA's consultation with EPA, a manufacturer's
application as part of the off-cycle credit approval process under 40
CFR 86.1869-12(b) or 40 CFR 86.1869-12(c) shall also be submitted to
NHTSA at the same time if the manufacturer is seeking off-cycle fuel
economy improvement values under the CAFE program for those
technologies. For off-cycle technologies which are covered under 40 CFR
86.1869-12(b) or 40 CFR 86.1869-12(c), NHTSA will consult with EPA
regarding NHTSA's evaluation of the specific off-cycle technology to
ensure its impact on fuel economy and the suitability of using the off-
cycle technology to adjust the fuel economy performance. NHTSA will
provide its views on the suitability of the technology for that purpose
to EPA. NHTSA's evaluation and review will consider:
    (1) Whether the technology has a direct impact upon improving fuel
economy performance;
    (2) Whether the technology is related to crash-avoidance
technologies, safety critical systems or systems affecting safety-
critical functions, or technologies designed for the purpose of
reducing the frequency of vehicle crashes.
    (3) Information from any assessments conducted by EPA related to
the application, the technology and/or related technologies; and
    (4) Any other relevant factors.

Note to Appendix Table II: With the appropriate fuel economy targets determined for each unique model type and footprint combination, Manufacturer X's
  required fleet average fuel economy standard would be calculated as illustrated in Appendix Figure 1:

Appendix Figure 1--Calculation of Manufacturer X's Fleet Average Fuel
Economy Standard Using Table II

Fleet average fuel economy standard =
[GRAPHIC] [TIFF OMITTED] TR15OC12.081

= 23.7 mpg

Appendix Figure 2--Calculation of Manufacturer X's Actual Fleet Average
Fuel Economy Performance Level Using Table I

Fleet average fuel economy performance =
[GRAPHIC] [TIFF OMITTED] TR15OC12.082

= 23.3 mpg

    Note to Appendix Figure 2:  Since the actual fleet average fuel
economy performance of Manufacturer X's fleet is 23.3 mpg, as
compared to its required fleet fuel economy standard of 23.7 mpg,
Manufacturer X did not comply with the CAFE standard for MY 2012 as
set forth in Sec.  533.5(i).

    (c) Adjustment factor. When traded or transferred and used, fuel
economy credits are adjusted to ensure fuel oil savings is preserved.
For traded credits, the user (or buyer) must multiply the calculated
adjustment factor by the number of its shortfall credits it plans to
offset in order to determine the number of equivalent credits to
acquire from the earner (or seller). For transferred credits, the user
of credits must multiply the calculated adjustment factor by the number
of its shortfall credits it plans to offset in order to determine the
number of equivalent credits to transfer from the compliance category
holding the available credits. The adjustment factor is calculated
according to the following formula:

    (b) If a manufacturer's calculated fuel economy for a particular
compliance category, including any statutorily-required calculations
for alternative fuel and dual fuel vehicles, is higher or lower than
the applicable fuel economy standard, manufacturers will earn credits
or must apply credits or pay civil penalties equal to the difference
between the calculated fuel economy level in that compliance category
