    (a) Unless otherwise exempted from specific emission compliance 
requirements, for each certification vehicle

defined in this part, and for each vehicle tested according to the 
emission test procedures in part 86 of this chapter for addition of a 
model after certification or approval of a running change (Sec. Sec. 
86.079-32, 86.079-33 and 86.082-34 or 86.1842-01 of this chapter, as 
applicable):
    (1) The manufacturer shall generate FTP fuel economy data by testing 
according to the applicable procedures.
    (2) The manufacturer shall generate highway fuel economy data by:
    (i) Testing according to applicable procedures, or
    (ii) Using an analytical technique, as described in Sec. 
600.006(e).
    (3) The manufacturer shall generate US06 fuel economy data by 
testing according to the applicable procedures. Alternate fueled 
vehicles or dual fueled vehicles operating on alternate fuel may 
optionally generate this data using the alternate fuel.
    (4) The manufacturer shall generate SC03 fuel economy data by 
testing according to the applicable procedures. Alternate fueled 
vehicles or dual fueled vehicles operating on alternate fuel may 
optionally generate this data using the alternate fuel.
    (5) The manufacturer shall generate cold temperature FTP fuel 
economy data by testing according to the applicable procedures. 
Alternate fueled vehicles or dual fueled vehicles operating on alternate 
fuel may optionally generate this data using the alternate fuel.
    (6) The data generated in paragraphs (a)(1) through (5) of this 
section, shall be submitted to the Administrator in combination with 
other data for the vehicle required to be submitted in part 86 of this 
chapter.
    (b) For each fuel economy data vehicle:
    (1) The manufacturer shall generate FTP and HFET fuel economy data 
by:
    (i) Testing according to applicable procedures, or
    (ii) Use of an analytical technique as described in Sec. 
600.006(e), in addition to testing (e.g., city fuel economy data by 
testing, highway fuel economy data by analytical technique).
    (2) The data generated shall be submitted to the Administrator 
according to the procedures in Sec. 600.006.
    (c) Minimum data requirements for labeling. (1) In order to 
establish fuel economy label values under Sec. 600.306-08, the 
manufacturer shall use only test data accepted in accordance with Sec. 
600.008-08 meeting the minimum coverage of:
    (i) Data required for emission certification under Sec. Sec. 
86.001-24, 86.079-32, 86.079-33, 86.082-34, 86.1828-01 and 86.1842-01 of 
this chapter, as applicable,
    (ii) (A) FTP and HFET data from the highest projected model year 
sales subconfiguration within the highest projected model year sales 
configuration for each base level, and
    (B) If required under Sec. 600.115-08, for 2011 and later model 
year vehicles, US06, SC03 and cold temperature FTP data from the highest 
projected model year sales subconfiguration within the highest projected 
model year sales configuration for each base level. Manufacturers may 
optionally generate this data for any 2008 through 2010 model years, 
and, 2011 and later model year vehicles, if not otherwise required.
    (iii) For additional model types established under Sec. 
600.208(a)(2) or Sec. 600.209(a)(2), FTP and HFET data, and if required 
under Sec. 600.115-08, US06, SC03 and Cold temperature FTP data from 
each subconfiguration included within the model type.
    (2) For the purpose of recalculating fuel economy label values as 
required under Sec. 600.314(b), the manufacturer shall submit data 
required under Sec. 600.507.
    (d) Minimum data requirements for the manufacturer's average fuel 
economy. For the purpose of calculating the manufacturer's average fuel 
economy under Sec. 600.510, the manufacturer shall submit data 
representing at least 90 percent of the manufacturer's actual model year 
production, by configuration, for each category identified for 
calculation under Sec. 600.510(a).
