Many of our readers have vowed not to buy another car until they can get one that features a plug. However, many others can't wait until affordable electric vehicles
become widely available. For those that need an affordable car that emits as little as possible and consumes not much more, there are options. The folks at NADAguides.com have compiled a list of the top five cleanest conventional cars currently available. Technically, the list actually contains only four unique cars, since the Chevy Cobalt and Pontiac G5 are the same car with different grilles. The other cars on the list are the MINI Cooper, Hyundai Elantra and Ford Focus. The list was based on the mileage, smog producing emissions and greenhouse gas emissions. All five models qualify as either PZEV or ULEV models in California.
