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. 600.006-86 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, and adjusted exhaust emission levels.
(ii) A statement of the origin of the vehicle including total
mileage accumulation, and modifications (if any) from 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 the 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 components performed within 2,000 miles prior to
fuel economy testing.
[[Page 864]]
(ii) In the case of electric vehicles, the manufacturer should
provide 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 actual components on the
test vehicle as well as the design tolerances.
(iv) In the case of electric vehicles, the manufacturer should
provide 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 in paragraph (b) 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 (other
than those chosen in accordance with Sec. 86.084-24 (c) and (h)), 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, if the data are
used in fuel economy label calculations, the 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 Sec. 86.084-21, 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 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.
(2) For vehicles with 6,200 miles (10,000 kilometers) or less
accumulated, the manufacturer is not required to adjust the data.
