From the Department of Unintended Consequences: Fuel Economy and Taxes.
Tom Vanderbilt’s Traffic: Why We Drive the Way We Do (and What It Says About Us) has been on my reading list for awhile, but I left the book in Colorado. I see he also has a related blog, which recently posted this interesting graphic on the history of vehicle fuel efficiency in the U.S.
It shows that the 1973 oil embargo helped stimulate innovation in fuel economy, with improvement continuing at a compound rate of 2% a year until 1991. Since then, overall fleet efficiency has improved at a compound rate of only 0.1% a year.
So what happened in the late 1980s to flatten the improvement? The rise of the SUV, of course.
The Corporate Average Fuel Economy (CAFE) standards inspired by the oil embargo contained a loophole wide enough to drive a three-ton truck through, by placing less stringent standards on vehicles used for business. Automakers made SUVs tall enough and heavy enough to qualify for the tax and fuel economy exemptions for trucks.
New York Times automotive writer Keith Bradsher argues in High and Mighty – SUVs: the World’s Most Dangerous Vehicles and How They Got That Way that the CAFE led to a forced choice for consumers — little econo-cars that met the new conservation guidelines or gas-guzzling SUVs.
According to the Transportation Safety Center,
Meanwhile, between 1975 and 1996, employment on farms — the supposed beneficiaries of the legislation — fell by nearly 27%.
