In the AAA Green Car Guide 2014, the top-ranking Tesla Model S P85 is closely followed by the Toyota RAV4 EV, Audi A7 TDI quattro Tiptronic, Lexus GS 450h and Nissan Leaf. If you factor in the price as well, then the best value green machine are as follows: Chevrolet Spark 1LT, Hyundai Elantra GLS, Nissan Versa SV, Scion iQ and Nissan Versa Note SV.
Compared to the quite expensive Tesla Model S P85, the Chevrolet Spark 1LT city-dweller is priced under $15,000 and averages nearly 30 miles per gallon, making it a pretty affordable eco-friendly machine. However, Mazor's heart has been won by the Palo Alto-based manufacturer's car: "The Tesla Model S is an incredible car. It’s the fastest green car we’ve ever tested: it rides and handles very well; it’s extremely quiet and stops on a dime."
AAA's Automotive Research Center Green Car Guide highlights consumer-friendly data and real-world evaluations to help car buyers in the market for eco-friendly vehicles. The selection process evaluates emission levels, fuel economy, crashworthiness, braking, acceleration, handling, cargo capacity, ride quality, ease of entry and exit, roominess, maneuverability and interior noise levels. Each vehicle included in the Green Car Guide is scored from one to 10 for each of the aformentioned qualities.
