The award for the most fuel efficient gas car of 2014 is the Chevy Cruze. With an expected 700+ highway tank (of course this depends on your driving habits), you really can’t go wrong. The model I’ll be discussing today is the 2.0 liter turbo-diesel. This vehicle starts off at a base price of $24,885. It pushes an unexpected 148 hp. With fuel economy and power, this car makes an ideal package for today society.
