PART 600_FUEL ECONOMY OF MOTOR VEHICLES--Table of Contents
Subpart A_Fuel Economy Regulations for 1977 and Later Model Year
Automobiles_General Provisions
Sec. 600.006-89 Data and information requirements for fuel economy vehicles.
(a) For certification vehicles with less than 10,000 miles, the
requirements of this section are considered to have been met except as
noted in paragraph (c) of this section.
(b)(1) The manufacturer shall submit the following information for
each fuel economy data vehicle:
(i) A description of the vehicle, exhaust emission test results,
applicable deterioration factors, adjusted exhaust emission levels, and
test fuel property values as specified in Sec. 600.113-93 except as
specified in paragraph (h) of this section.
(ii) A statement of the origin of the vehicle including total
mileage accumulation, and modification (if any) form the vehicle
configuration in which the mileage was accumulated. (For modifications
requiring advance approval by the Administrator, the name of the
Administrator's representative approving the modification and date of
approval are required.) If the vehicle was previously used for testing
for compliance with part 86 of this chapter or previously accepted by
the Administrator as a fuel economy data vehicle in a different
configuration, the requirements of this paragraph may be satisfied by
reference to the vehicle number and previous configuration.
(iii) A statement that the fuel economy data vehicle, with respect
to which data are submitted:
(A) Has been tested in accordance with applicable test procedures,
(B) Is, to the best of the manufacturer's knowledge, representative
of the vehicle configuration listed, and
(C) Is in compliance with applicable exhaust emission standards.
(2) The manufacturer shall retain the following information for each
fuel economy data vehicle, and make it available to the Administrator
upon request:
(i) A description of all maintenance to engine, emission control
system, or fuel system, or fuel system components performed within 2,000
miles prior to fuel economy testing.
(ii) In the case of electric vehicles, a description of all
maintenance to electric motor, motor controller, battery configuration,
or other components performed within 2,000 miles prior to fuel economy
testing.
(iii) A copy of calibrations for engine, fuel system, and emission
control devices, showing the calibration of the
[[Page 871]]
actual components on the test vehicle as well as the design tolerances.
(iv) In the case of electric vehicles, a copy of calibrations for
the electric motor, motor controller, battery configuration, or other
components on the test vehicle as well as the design tolerances.
(v) If calibrations for components specified in paragraph (b)(2)
(iii) or (iv) of this section were submitted previously as part of the
description of another vehicle or configuration, the original submittal
may be referenced.
(c) The manufacturer shall submit the following fuel economy data:
(1) For vehicles tested to meet the requirements of 40 CFR part 86
(other than those chosen in accordance with 40 CFR 86.1829-01(a) or 40
CFR 86.1844-01), the city and highway fuel economy results from all
tests on that vehicle, and the test results adjusted in accordance with
paragraph (g) of this section.
(2) For each fuel economy data vehicle, all individual test results
(excluding results of invalid and zero mile tests) and these test
results adjusted in accordance with paragraph (g) of this section.
(d) The manufacturer shall submit an indication of the intended
purpose of the data (e.g., data required by the general labeling program
or voluntarily submitted for specific labeling).
(e) In lieu of submitting actual data from a test vehicle, a
manufacturer may provide fuel economy values derived from an analytical
expression, e.g., regression analysis. In order for fuel economy values
derived from analytical methods to be accepted, the expression (form and
coefficients) must have been approved by the Administrator.
(f) If, in conducting tests required or authorized by this part, the
manufacturer utilizes procedures, equipment, or facilities not described
in the Application for Certification required in 40 CFR 86.087-21 or 40
CFR 86.1844-01 as applicable, the manufacturer shall submit to the
Administrator a description of such procedures, equipment, and
facilities.
(g)(1) The manufacturer shall adjust all test data used for fuel
economy label calculations in subpart D and average fuel economy
calculations in subpart F for the classes of automobiles within the
categories identified in paragraphs (a)(1) through (6) of Sec. 600.510.
The test data shall be adjusted in accordance with paragraph (g) (3) or
(4) as applicable.
(2) [Reserved]
(3) The manufacturer shall adjust all test data generated by
vehicles with engine-drive system combinations with more than 6,200
miles by using the following equation:
FE4,000mi=FET[0.979+5.25x10-6
(mi)]-1
Where:
FE4,000mi=Fuel economy data adjusted to 4,000-mile test point
rounded to the nearest 0.1 mpg.
FET=Tested fuel economy value rounded to the nearest 0.1 mpg.
mi=System miles accumulated at the start of the test rounded to the
nearest whole mile.
(4) For vehicles with 6,200 miles or less accumulated, the
manufacturer is not required to adjust the data.
(h) For light-duty fuel economy trucks over 6000 lbs GVWR, the
manufacturer must submit emissions data generated while using the
following test weight basis:
(1) Adjusted Loaded Vehicle Weight (ALVW) as defined in Sec.
86.094-2 of this chapter; or
(2) Loaded Vehicle Weight (LVW) as defined in Sec. 86.082-2 of this
chapter, in which case the Administrator reserves the right to either
require the manufacturer to test using ALVW and submit the data or
submit the vehicle for testing by the Administrator for emission
standards compliance.
