Tesla Motors Elon Musk has issued an email confessing that it had no idea actual production costs for the $92,000 Roadster would run closer to $140,000. The automaker is hoping the changes in "manufacturing approaches, the car's drive train, heating and air conditioning system, wiring and even the supplier of body panels" will lower production costs to somewhere between $90,000 and $100,000 soon, which certainly gives a little insight into the $128,500 starting price of the recently unveiled Roadster Sport. In order to recoup some of the losses, Tesla is asking pre-orderers to pony up an extra six large for a high-speed charging cable and custom wheels -- both of which consumers were expecting to be included in their original purchase price. At any rate, the firm is aiming to get build costs down to $80,000 by summer, with profitability following close behind. And you thought the automotive problems began and ended in Detroit.
Update: Response from Tesla is after the break.
