What Does HFET Stand For?
HFET stands for Highway Fuel Economy Test
HFET, or Highway Fuel Economy Test, is a standardized procedure used to evaluate the fuel efficiency of vehicles during highway driving conditions. This test simulates real-world highway scenarios, allowing manufacturers and regulatory agencies to assess and compare the fuel economy performance of different vehicles. The results are essential for consumers seeking to make informed decisions about vehicle purchases and for compliance with environmental regulations.
