Fuel efficiency in the U.S. new-car market continues to improve. The average fuel economy for new cars sold in 2012 increased to 23.1 mpg — up from 22.3 mpg in 2011 — according to TrueCar, Inc., a national car-sales tracking organization. That 0.8 mpg increase translates to a reduction in fuel consumption of 348 million gallons, or an annual savings of about $1.2 billion in U.S. fuel costs.

The 2013 Nissan Leaf (shown) is now being produced in Tennessee. Nissan announced this month that production of the all-electric car had begun in Smyrna, also the site of the Nissan plant that produces the Leaf's lithium-ion battery. The new Leaf features faster charging and what will likely be an extended driving range.
