IRVINE, Calif., and McLEAN, Va. -

As Earth Day approaches, and the weather continues to warm as spring gets underway, buyers may be interested in the "greener" cars on your lots.

For dealers looking to market to eco-friendly drivers, Kelley Blue Book compiled a list of the 10 Best Green Cars of 2013, chosen by editors of KBB.com.

The list includes the new Nissan Leaf, the 2013 Toyota Avalon and more, ranging the gamut from electric to more traditional fuel-efficient vehicles.

In recent years, with the launch of many new electric models, including the Nissan Leaf and Chevy Volt, green cars "really have gone mainstream," Kbb.com editors contend. And many of the country’s best-selling cars, such as the Honda Civic, have been released in hybrid or pure electric form, as well.

"A growing number of both eco-conscious drivers are going 'green' when it comes to the new car they choose to drive, and auto manufacturers have primed the pump with the widest array of offerings in the 'green car' segment than ever before," said Jack Nerad, executive editorial director and executive market analyst for KBB.com. 

"After driving and testing nearly every new vehicle on the market today, our editors compiled a '10 Best Green Cars' list that provides a roadmap for consumers looking to get more miles from each gallon of gasoline or to eliminate gasoline altogether."

More On Leaf & Volt

Over at NADA Used Car Guide, the latest Guidelines report offered some interesting statisticis on two of those vehicles: the Nissan Leaf and Chevy Volt.

NADA UCG's Jonathan Banks said in the report that sales “exploded for the Leaf in March, as the brand sold 2,197 units of the all-electric car.”

He added: “Over the first few months of the year, the Leaf’s year-to-date sales average has been about 650 units per month, or less than a third of what was sold in March alone.”

Why the sales jump?

Banks attributed the rise to a “dramatic reduction” in new-vehicle price.

Nissan cut the price of the 2013 Leaf by $6,400, which brought the price down to roughly $28,800, not including destination, officials reported.

On the other hand, the Volt’s sales for March showed a 35-percent drop (month-over-month), selling 1,478 new Volts — 719 units less than the Nissan Leaf.
