Over 1,000,000 vehicles have been sold that get over 30 miles per gallon in a single year. Many people in the health and fashion industries are fond of saying things like, “30 is the new 20”. Now, automakers are starting to say it too.

Thirty miles per gallon is a sweet spot in the auto industry — far better than the underwhelming 20 MPG threshold, but not quite 40 MPG, which can require automakers to shrink vehicles or deploy costly hybrid technology. Now, General Motors says that it has become the first U.S. automaker to sell over 1,000,000 vehicles that achieve 30 MPG within a single year.

According to a company press release, GM currently offers 13 high-volume models that achieve 30 MPG or better.
