Typically, the cycle under consideration would be one of the federal test procedure (FTP) driving cycles such as the urban or highway schedule.
If MERF is computed for both FTP cycles, a MERF related to corporate average fuel economy (CAFE) can be computed as indicated in Equation 8.
This is a MERF computed at the standard reference conditions discussed above. (88)
