§ 600.101 Testing overview.
Perform testing under this part as described in § 600.111. This involves the following specific requirements:
(a) Perform the following tests and calculations for LDV, LDT, and MDPVFE:
(1) Testing to demonstrate compliance with Corporate Average Fuel Economy standards and greenhouse gas emission standards generally involves a combination of two cycles—the Federal Test Procedure and the Highway Fuel Economy Test (see 40 CFR 1066.801). Testing to determine values for fuel economy labeling under subpart D of this part generally involves testing with three additional test cycles; § 600.210 describes circumstances in which testing with these additional test cycles does not apply for labeling purposes.
(2) Calculate fuel economy and CREE values for vehicle subconfigurations, configurations, base levels, and model types as described in §§ 600.206 and 600.208. Calculate fleet average values for fuel economy and CREE as described in § 600.510.
