Fuel economy is a major selling point for any vehicle these days. And while new cars are required to display details on fuel efficiency, it’s left up to the consumer to find out such information on used cars. Now, however, there's a new tool to help in that search.

Just added to the U.S. Department of Energy’s Fuel Economy dot gov website, the Used Car Fuel Economy Label tool will help buyers and sellers alike more easily access the details about a vehicle’s fuel economy and environmental impact.

Users simply choose the year, make, and model from a database of vehicles going back to the 1984 model year. A label is then generated, which can be printed or downloaded as a graphic to post in an on-line ad or auction listing.

Last year alone over 40 million used cars were sold in the U.S.

The new labels allow used car buyers to more easily join new car consumers in making better choices when it comes to fuel efficient vehicles. And that's it for this week's MotorNews.
