TITLE 40--PROTECTION OF ENVIRONMENT
CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
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. 600.006-08 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. 600.113-08.
(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 for 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
[[Page 867]]
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 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 part 86 of this
chapter (other than those chosen in accordance with Sec. Sec. 86.1829-
01(a) or 86.1845 of this chapter, the FTP, highway, US06, SC03 and cold
temperature FTP fuel economy results, as applicable, 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.
(3) For diesel vehicles tested to meet the requirements of part 86
of this chapter, data from a cold temperature FTP, performed in
accordance with Sec. 600.111-08(e), using the fuel specified in Sec.
600.107-08(c).
(4) For all vehicles tested in paragraph (c)(1) through (3) of this
section, the individual fuel economy results measured on a per-phase
basis, that is, the individual phase results for all sample phases of
the FTP, cold temperature FTP and US06 tests.
(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 Sec. 86.1844-01 of
this chapter, 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 of Sec. 600.510(a)(1) through (4).
The test data shall be adjusted in accordance with paragraph (g)(3) or
(4) of this section 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.
