Nissan CEO Carlos Ghosn has acknowledged the company will fall short of its 2012 sales goals for its electric battery car, the Nissan Leaf. After a sharp downturn early this year, however, sales of the mass-market electric vehicle took a sharp turn upward last month – and Nissan is expecting to see an even bigger shift in momentum when it opens its all-new U.S. battery car assembly line next month. Nonetheless, “The forecast we have given ourselves for the year will not be reached,” Ghosn acknowledged during an interview on Bloomberg Television.
