    The definitions of Sec. 86.098-2 continue to apply to 1998 and later 
model year vehicles. The definitions listed in this section apply 
beginning with the 2000 model year.
    AC1 means a test procedure as described in Sec. 86.162-00 which 
simulates testing with air conditioning operating in an environmental 
test cell by adding the air conditioning compressor load to the normal 
dynamometer forces.

    AC2 means a test procedure as described in Sec. 86.162-00 which 
simulates testing with air conditioning operating in an environmental 
test cell by adding a heat load to the passenger compartment.
    Alternative fuels means any fuel other than gasoline and diesel 
fuels, such as methanol, ethanol, and gaseous fuels.
    866 Cycle means the test cycle that consists of the last 866 seconds 
(seconds 505 to 1372) of the EPA Urban Dynamometer Driving Schedule, 
described in Sec. 86.115-00 and listed in appendix I, paragraph (a), of 
this part.
    Environmental test cell means a test cell capable of wind-speed, 
solar thermal load, ambient temperature, and humidity control or 
simulation which meets the requirements of Sec. 86.161-00 for running 
emission tests with the air conditioning operating.
    Federal Test Procedure, or FTP means the test procedure as described 
in Sec. 86.130-00 (a) through (d) and (f) which is designed to measure 
urban driving tail pipe exhaust emissions and evaporative emissions over 
the Urban Dynamometer Driving Schedule as described in appendix I to 
this part.
    505 Cycle means the test cycle that consists of the first 505 
seconds (seconds 1 to 505) of the EPA Urban Dynamometer Driving 
Schedule, described in Sec. 86.115-00 and listed in appendix I, 
paragraph (a), of this part.
    SC03 means the test cycle, described in Sec. 86.160-00 and listed in 
appendix I, paragraph (h), of this part, which is designed to represent 
driving immediately following startup.
    Supplemental FTP, or SFTP means the additional test procedures 
designed to measure emissions during aggressive and microtransient 
driving, as described in Sec. 86.159-00 over the US06 cycle, and also 
the test procedure designed to measure urban driving emissions while the 
vehicle's air conditioning system is operating, as described in 
Sec. 86.160-00 over the SC03 cycle.
    US06 means the test cycle, described in Sec. 86.159-00 and listed in 
appendix I, paragraph (g), of this part, which is designed to evaluate 
emissions during aggressive and microtransient driving.
