My recent cross-country drive from Philadelphia to Colorado made one issue painfully clear – gas prices are on the rise today in America. Nationwide, the average gallon of regular gas today stands at $3.88, and rises to $4.27 in Chicago. These escalating gas prices are encouraging citizens of the United States to invest in eco-friendly vehicles.  Here’s a list of the Top 5 Fuel Efficient Vehicles (non-electric) currently on the market as rated by the U.S. Department of Energy:

1. 2011 Toyota Prius … mpg: 51 city

2. 2011 Ford Fusion … mpg: 41 city

3. 2011 Honda Civic Hybrid … mpg: 40 city

4. 2011 Honda CR-Z … mpg: 35 city

5. 2011 Lexus HS 250h … mpg: 35 city
