The California-based firm said it earned a profit of $11 million in the first quarter as revenues rose 83 percent from the prior quarter to $562 million. \"Tesla reached profitability in the first quarter of 2013 for the first time in our 10-year history,\" a company statement said. \"We exceeded our own targets for deliveries, significantly expanded gross margin, and improved execution throughout the company.\" The statement said \"we consistently produced 400 or more Model S vehicles per week, for a total of over 5,000 during the quarter\" and counted revenues from vehicles. Tesla cited \"strong global demand for Model S\" saying it is \"currently receiving orders at a rate greater than 20,000 per year worldwide\" and noted that it seen \"significant upside potential in Europe and Asia.\" Tesla conducted an initial public offering in 2011, raising $226 million. The first model, the Tesla Roadster, cost more than $100,000 and can go nearly 250 miles (400 kilometers) on a single charge. It later launched the Model S, starting at $49,900, but with financing, tax incentives and resale guarantees aimed at winning over consumers.
