Tesla was cash flow positive last week, CEO Musk says

Tesla Motors Inc., the maker of electric vehicles led by billionaire Elon Musk, was cash flow positive last week, the CEO said Monday in a posting on Twitter.

"Am happy to report that Tesla was narrowly cash flow positive last week," Musk, 41, wrote in the message to his more than 112,000 followers. "Continued improvement expected through year end." Musk’s message, which was re-posted more than 500 times by Twitter users, provided no additional information.

Tesla, which hasn't turned a quarterly profit, is racing to expand production of the rechargeable Model S sedan at its factory in Fremont, Calif. The base price of the car will increase by $2,500 to $59,900 on Jan. 1, the California-based company said last week in a statement.

The Model S last month was named 2013 “Car of the Year" by Motor Trend magazine, the first time the award has gone to an electric vehicle. Tesla has said it will build at least 20,000 of the cars at the Fremont plant next year, and add the Model X electric SUV in 2014.

The Model S, which qualifies for a $7,500 tax credit, travels between 160 miles (257 kilometers) and 300 miles solely on electricity, depending on the size of battery pack purchased
