U.S. automakers have reached an agreement with the government to require fuel economy on new cars of 54.5 mpg by 2025- more than double today's average fuel economy of 27 mpg. This new standard will be phased in at the rate of 5% improvement a year, starting in 2017. This is expected to add $6,000 to the price of new cars. It will also result in smaller, lighter (and perhaps, less safe) cars.

Hang on to your Hemis! They will shortly be dinosaurs.
