Despite making everyone's favorite electric vehicle (EV), Tesla still loses more than $4,000 on every Model S it sells, according to a report from Reuters. The report also says that Tesla has cut production targets for 2015 and 2016, and the company is also apparently considering raising more capital.

Tesla is still relying on a single model, its Model S sedan. During the second quarter 2015, it delivered 11,532 of these cars and made an operating loss of $47 million. Meanwhile, Tesla is hard at work on the forthcoming Model X SUV—due to arrive early next year—and 2017's Model 3, which should combine a 200-mile range with a $30,000 price tag. And there's the "Gigafactory," a Li-ion battery plant being built near the aptly named Sparks, Nevada.

With just one model on sale to support all its R&D, it's understandable why a share sale might be on the horizon. When you look at Tesla's finances the same way that GM and Ford report theirs (generally accepted accounting principles, or GAAP), the company lost nearly $15,000 per car this last quarter. Although Tesla says this number is more than covered by income from EVs it leases direct to customers, designing and developing cars is neither cheap nor simple, and the company will need cash to grow into a multiple-model lineup.

Meanwhile, California's generous subsidies for wealthy EV buyers recently got a lot less generous, and Chevrolet looks like it will beat Tesla to market with an affordable long-range EV, the Bolt, due next year. 2016 might be a tougher one for Tesla.
