Tesla is currently growing by about 50% year over year. That amount of growth alone would eat up most profits made on the car sales. On top of that they have the costs of the imminent launch of the Model X. And, in the next weeks they are going to open their 500th Supercharger site world-wide. No other car manufacturer is building up a charger network of that scale. Finally their Gigafactory is making good progress, supposedly going operational in 2016. So currently they intentionally burn through their cash reserves to strenghten their future business.
