A previous report we brought you on how Tesla was teaming up with Toyota to build electric cars in California now needs to be slightly clarified. This recent update is based on a recent IPO statement from Tesla that states that although the two companies announced their intention to cooperate on Tesla Model S electric car development, they have not made any formal agreements to do so and may never at all.

While it still remains true that Tesla and Toyota will be sharing space at the NUMMI factory as well as some strategies, it definitely brings potential investors a dose of reality as Tesla prepares to be publically traded on the Nasdaq.

Toyota CEO Akio Toyoda, Tesla Motors CEO Elon Musk and California Governor Arnold Schwarzenegger held a joint press conference today in which they announced that Toyota would be teaming up with Tesla to produce the Model S electric car in California.

Tesla Model S production will take place in the recently closed NUMMI factory in Fremont. Toyota, the previous owner of the factory, will invest $50 million for a private placement of Tesla common stock and will a production system and possibly some of Toyota’s suppliers.

Schwarzenegger, for his part, offered a sales tax abatement to Tesla for all capital equipment expenditures in retooling the factory. Tesla estimates put the value of the abatement at approximately $20 million over the course of three years or so.

Tesla stated that the Model S production will likely see the return of about 1,000 of the former Toyota factory employees as they look to produce about 20,000 Model S electric cars per year. Tesla also hinted at the possibility of increasing production to a point of requiring  10,000 workers.
