An anonymous reader quotes a report from Reuters: Tesla Motors Inc reported its 13th straight quarterly loss as a rise in sales of its Model S and Model X electric cars failed to make up for the huge cost of ramping up production. The company, run by Silicon Valley entrepreneur Elon Musk, said on Wednesday it was on track to deliver about 50,000 new Model S and Model X vehicles during the second half of 2016. Shares of Tesla, which has offered to buy solar panel installer SolarCity Corp for $2.6 billion, were volatile in after-hours trading. They were last up 1 percent. Tesla delivered 14,402 vehicles in the second quarter, missing its goal of 17,000. It delivered 14,810 vehicles in the first quarter, which was also less than its expectations. Tesla said its net loss widened to $293.2 million, or $2.09 per share, in the second quarter, from $184.2 million, or $1.45 per share, a year earlier. Total revenue rose 33 percent to $1.27 billion in the quarter ended June 30. In addition to acquiring SolarCity, Tesla has unveiled its massive $5 billion Gigafactory in Nevada last week and announced its "Master Plan, Part Deux" not too long before that, which includes manufacturing electric trucks and buses, as well as a ride-sharing program.
