Cars got quicker, more powerful by weight, and more fuel efficient in the last 40 years.

Over the past 40 years, light-duty vehicles in the United States have achieved remarkable gains in both fuel economy and performance. The graph below shows average miles per gallon, power-to-weight ratio, and 0-to-60 acceleration time of new cars and light trucks since the late 1970s. Fuel economy improved dramatically from 1975 to 1987, driven by the original Corporate Average Fuel Economy (CAFE) standards, which were adopted in 1975 in response to the 1973 oil embargo by Arab states.

Implementation of clean vehicle standards: How’s it going?

Standards cutting greenhouse gas emissions from cars and light trucks and raising fuel economy are among the biggest environmental achievements of the Obama administration. The standards are projected to save consumers hundreds of billions of dollars in fuel expenditures over the next decade. In the process, they are helping to shape the US and global auto industries by establishing an expectation of continuing technological progress toward high efficiency, low-emitting vehicles.

Fuel economy standards will propel America’s vehicle technology, if we let them.

In his State of the Union address, President Obama rightly pointed to a thriving domestic auto industry as a bright spot in the U.S. economy. It’s a good time to recall that the government’s 2008-2009 intervention on behalf of GM and Chrysler played a big role in that outcome, as did energy efficiency.
