The 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 following are some characteristic parameters of the cycle:

  • Duration: 765 seconds
  • Total distance: 10.26 miles (16.45 km)
  • Average Speed: 48.3 mi/h (77.7 km/h)
