Ready for the Whitestar? CNET is, and recently interviewed Tesla's co-founder, Elon Musk, about the eagerly-anticipated next vehicle from Tesla Motors. Elon says some things we know - the electrically-powered sedan will cost between $50,000 and $60,000 and is estimated to sell 10,000 to 20,000 units a year. He also reveals that the name might change and that the design will be finalized by the second quarter of 2008. A working prototype should follow by the end of the year -- big news, indeed. Musk mentions the "default location" or "most likely" location for the Whitestar production plant is Albuquerque, which, based on earlier reports, is not surprising.
