Sec. 600.006-87  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 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.
    (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 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 (other 
than those chosen in accordance with Sec. 86.085-24 (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 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

[[Page 870]]

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. 86.087-21, 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 in subpart D and average fuel economy 
calculations in subpart F for passenger automobiles within the 
categories identified in paragraphs (a)(1) and (a)(2) of Sec. 600.510. 
The test data shall be adjusted in accordance with (g)(3) or (g)(4) as 
applicable.
    (2) The manufacturer shall only adjust the test data used for fuel 
economy label calculations, in subpart D for light trucks within the 
categories identified in paragraphs (a)(3) through (a)(6) of Sec. 
600.510. The test data shall be adjusted in accordance with (g)(3) or 
(g)(4) as applicable.
    (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+5.25 x 10-6 
    (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.
