US: Light-duty: HWFET

The Highway Fuel Economy Cycle (HWFET) cycle is a chassis dynamometer driving schedule, developed by the US EPA for the determination of fuel economy of light duty vehicles [40 CFR part 600, subpart B]. The HWFET is used to determine the highway fuel economy rating, while the city rating is based on the FTP-75 test.
