Just in time for Earth Day, Kelley Blue Book editors picked the 10 Best Green Cars of 2014 to assist eco-friendly drivers in the market for a new vehicle.

While Honda was the only brand to have two models included, taking the top spot on this annual list for 2014 was the all-new, all-electric BMW i3. 

Each year, the KBB.com editors compile a list of the most efficient vehicles available and then pick 10 standouts featuring a variety of price ranges and powertrains. 

More than just a compilation of the most fuel-efficient vehicles, KBB insisted the list also takes into account production methods and recyclability, and the editors try to seek vehicles appropriate for varying lifestyles. With more environmental-focused models available every year, choosing the 10 best among the pack is proving to be a challenging task.

“Each year both the quantity and quality of ‘green’ cars is improving, offering a growing number of choices for environmentally friendly buyers at a wider range of prices,” said Jack Nerad, executive editorial director and executive market analyst for Kelley Blue Book.

“The all-new BMW i3 is our top pick this year,” Nerad continued. “Built at an ecologically friendly plant, the i3 is offered in all-electric and gasoline-assisted range-extender versions, and it features an ultra-light carbon-fiber body to help squeeze maximum range from its battery pack.  Its interior boasts plenty of recycled materials and door panels formed from visible natural fibers.”
