Toyota Prius Retains Fuel Economy Crown

Despite a slew of new hybrids joining the market this past year, the Toyota Prius retains the top spot as the most fuel efficient vehicle in the U.S. There is a catch, however, with no electric vehicles (like the Nissan Leaf or Chevy Volt) being included in this year’s round of testing – yet.

With a rating of 51/48-mpg (city/highway) the Prius easily out-paces the second-place Fusion Hybrid, as well as the Lincoln MKZ Hybrid and Mercury Milan Hybrid at 41/36-mpg. In third spot are the Honda Civic Hybrid and Insight at 40/43-mpg.

The new Honda CR-Z places 4th with the CVT transmission (but 10th with the manual). Hyundai’s new Sonata Hybrid has not yet been tested either, although it should out-rank the Fusion Hybrid to fit into second place.
