From what we know today, pretty much everything about the all-electric Nissan Leaf is getting bigger and/or better in 2012. From availability in Europe to 50-state availability and production in the States, it’s clear Nissan is planning big things for its EV this year. Now, Nissan’s Mark Perry has told the The Detroit News that the 2013 Leaf will get serious improvements when it launches later this year, including a better heater, a darker interior color choice and leather seats. The new Leaf will be made in Smyrna, TN. Funk Flex
