It's amazing what a little regulation can do for an industry. In the past four years, the fuel economy of new vehicles has improved by an average of 14 percent, according to a new study by the University of Michigan. This increase comes on the heels of big hikes in the Corporate Average Fuel Economy, which Congress raised in 2007 for the first time in decades. Since then, CAFE has been set at 34.1 miles per gallon by 2016, and a new proposal that's pending would raise the fuel economy standard to 54.5 mpg by 2025.
