Tires and Passenger Vehicle Fuel Economy: Informing Consumers, Improving Performance - TRB Special Report 286
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.

Standard MERF
This is a MERF computed at the standard reference conditions discussed above. (88)
