HWFET definition
Examples of HWFET in a sentence
The first case combines repeats of the urban dynamometer driving schedule (UDDS) and the highway fuel economy test (HWFET) until the storage systems is depleted.
The fuel economy is calculated using the current Environmental Protection Agency (EPA) five-cycle procedure of adjusting and weighting the UDDS and HWFET to provide one fuel economy figure that represents real-world use—it is not the raw figures that come directly from running the cycles.
Similarly, the range is then calculated from the adjusted and weighted UDDS and HWFET figure and not simply the miles achieved until the hydrogen storage system is empty.
It uses a 55%/45% weighting factor between UDSS (city) versus HWFET (highway) driving.
