CARS:
From 1978 to 1990 the US government increased CAFE from 18 mph to 27.5 mpg. From 1991 to 2010 they held CAFE steady at 27.5 mpg. From 2011 to 2020 CAFE steadily increased from 27.5 to 40.9 mpg
TRUCKS:
CAFE went from 17.5 mpg in 1982 to 20.5 in in 1989. In 1990 CAFE requirements actually dropped to 20 then climbed back to 20.7 in 1996. From 1996 to 2004 it held steady at 20.7 mpg. For 2005 to 2020 truck fuel economy climbed steadily to 31 mpg.
When the government requires manufacturers to increase fuel economy they do. That is the only time we increase fuel economy. |
Generally, it is a good idea to read the next sentence before replying. CAFE was a rare example of regulating results, not means. The push for electrics, with no limits on consumption, is a typical bad one.
