A confluence of global warming & dwindling recoverable petroleum resources has led the automotive industry in the United States to agree to meet a corporate average fuel economy (CAFE) figure of 54.5 mpg (US) by 2025.
Toyota's Prius exceeds this requirement now. The challenge is contained in the "C" for corporate in "CAFE". That's a corporate average fuel economy figure. I.e. it takes into account all vehicles in a corporation's model range. For Toyota, that includes not only the Prius, but it's largest pickup & everything else in between.
John Voelcker takes a look at how this will change cars in the USA. Look for something very similar in your country too:
