50-state car
n.— «Many of the cars that are produced today are called 50-state cars: they don’t have an EPA version and a California version. In other words, the vehicle meets the strictest standard that’s out there, whether it’s EPA for a certain pollutant, or California for a certain pollutant, and then they sell the same vehicles in all 50 states.» —“Obama’s action gives clean car backers a boost” by Stephanie Hemphill Minnesota Public Radio Jan 26, 2009.
