The US Department of Energy and the EPA have a pretty informative site on fuel economy, http://www.fueleconomy.gov/. You can compare cars side by side for mpg (miles per gallon), safety, greenhouse gas emissions, and more. There is information on hybrid vehicles and tax rebates offered, finding the lowest gas prices, how to drive more efficiently, and more. You can even calculate the mpg you get on your current car and compare to other people with the same or similar car. One example of the suggestions to improve your gas mileage is to make sure you aren’t carry any excess weight. It may be time to clean out the trunk or back of your car and remove anything that doesn’t need to be there.
