There is no arguing that the Honda Civic is a great car offering good handling, ample comfort, and noteworthy fuel economy. So how do you make a car with so many positive attributes even better? Power it with compressed natural gas (CNG), making it not only a good vehicle for you but also a good vehicle for the environment. Factor in top EPA scores for pollution and greenhouses gases, and suddenly selecting the Honda Civic GX as the Best Non-Hybrid for the Environment becomes a no-brainer.
