Additional notes: The top 4 best-selling passenger cars are the Honda Accord and Civic, and the Toyota Camry and Corolla [1]. Their "combined city/highway" fuel efficiences are respectively 30, 34, 27, and 32 mpg for the base engine [2][3][4][5]. How can this possibly work out to 37 mpg overall? There aren't enough hybrid sales to bring that number up.
