Nissan sold more cars in 2011 than ever before.

Record-high sales helped Nissan to overcome natural disasters and the rising value of the yen to post a full-year operating profit of $6.9 billion. Nissan's fiscal year came to a close on March 31.

Nissan sold a record-high 4.845 million vehicles worldwide last year, marking a 15.8 percent improvement over fiscal year 2010. Nissan's global market share grew 0.6 percent during the 12-month period, giving the automaker a 6.4 percent take of the overall market.

"Nissan has delivered robust operating profits and record sales amid growing demand for our models, brands and technologies around the world," said Carlos Ghosn, Nissan President and Chief Executive Officer. "It is an even more encouraging performance given the headwinds created by natural disasters, an over-valued yen and uncertain global economic conditions."

China was easily Nissan largest single market last year, with sales increasing 21.9 percent to 1,247,000 units. The United States held the second spot, with sales up 11.8 percent to 1,080,000 vehicles.

Things look even brighter for the 2012 fiscal year, with Nissan calling for another 10.4 percent increase to 5.35 million global deliveries. Nissan is also gunning for a 10 percent share of the United States market.
