context_page_description: The EPA Federal Test Procedure, commonly known as FTP-75 for the city driving cycle, are a series of tests defined by the US Environmental Protection Agency to measure tailpipe emissions and fuel economy of passenger cars.
  The testing was mandated by the Energy Tax Act of 1978 in order to determine the rate of the guzzler tax that applies for the sales of new cars.
  The current procedure has been updated in 2008 and includes four tests: city driving, highway driving, aggressive driving, and optional air conditioning test.
context_section_description: The "highway" program or Highway Fuel Economy Driving Schedule (HWFET) is defined in 40 C.F.R. 600 Appendix I.
  It uses a warmed-up engine and makes no stops, averaging 48 mph (77 km/h) with a top speed of 60 mph (97 km/h) over a 10-mile (16 km) distance.
  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)
  The measurements are adjusted downward by 10% (city) and 22% (highway) to more accurately reflect real-world results.
