Tesla Model S

According to Bloomberg, Tesla actually earned money last week. CEO Elon Musk sent out a message on Twitter saying his company was "narrowly cash positive." That's big news for a company that hasn't turned a quarterly profit as of yet. Tesla is currently in the middle of stepping up production for its Model S sedan, and has announced the vehicle's MSRP will jump by $2,500, presumably to help fund that expansion.

So far, Tesla says it has built will build around 20,000 Model S units at its California production facility next year, though analysts say the ability to repeatedly generate a positive cash flow would go a long way toward the company's evolution into a "sustainable operating entry." So far, the Model S has garnered substantive praise, earning the Motor Trend Car of the Year Award among others. Tesla shares are up 19 percent this year over the same time period in 2011.
