How have C.A.F.E. cars regulations changed over the past few decades?
• According to NPR‘s history file, “The standards ushered in an early surge in fuel economy for new cars and trucks. But CAFE requirements haven’t changed much in more than a decade — and neither has the gas mileage of the vehicles that Americans drive.” However, in 2009, United States President Barack Obama signed into law new directives that new car manufacturers should seek to meet or exceed new regulations by or before the year 2016. The new bar for production standards says all vehicles (including cars, SUVs, cross over vehicles, and light trucks) should have reduced emissions and meet 35.5 MPG or better fuel economy.
