The Hyundai Elantra has been one of the most popular cars on the road recently, but the company is still making some changes for its upcoming 2012 model. USA Today reports that the manufacturers will include a number of upgrades that will focus on improving the car's fuel economy.

In particular, Hyundai will outfit all the compact sedans with the so-called Active Eco System. This upgrade works by smoothing out throttle response, which can help boost fuel economy by as much as seven percent. The move could be a big one, as the car is already among the most fuel-efficient on the road.

The expected changes for the 2012 model will not just be efficiency-related, however. According to the news source, Hyundai will also add some new safety features such as improved fog lights, a louder horn and a passenger-side sun visor extender.

Drivers interested in the purchasing the Hyundai Elantra may want to hold off until the new version is released. However, if one is looking for a used car they may want to turn to New Jersey State Auto Auction, which offers used Hyundais at an affordable price.
