$49,900 after tax credit

Elon Musk has disclosed the intended price of Model S, even if the car itself must spend another week under wraps. And another two years before production cars begin to roll off an assembly line. According to the Tesla newsletter "the Model S will have an anticipated base price of $57,400. After a federal tax credit of $7,500, the effective price will be $49,900."

If you live in a state that adds further incentives for plug-ins, such as Texas or California, you're looking at perhaps $45,000. Not bad.
