The Nissan Leaf (also formatted LEAF as a backronym for leading environmentally-friendly affordable family car) is a compact five-door hatchback electric car manufactured by Nissan and introduced in Japan and the United States in December 2010.
It seems Nissanâs engineers were up for that challenge though, as the Leaf is an exceptional vehicle â one that could turn the tide for all-electric cars in the U.S. The 2012 Leaf is powered by an 80-kW AC synchronous electric motor, and stores its energy in a 24-kWh lithium-ion battery pack. That equipment grants it a real-world driving range of 70 to 100 miles on a full charge.
