Tesla's 'Bluestar' to be all-electric family car | Green Tech - CNET News

The company intends to make a "family car" that it hopes will lead to the sale of millions of all-electric vehicles, JB Straubel, Tesla's chief technology officer, said Wednesday. He spoke earlier on a panel on "green transportation" at the EmTech 2008 conference here.

Code-named Bluestar, the car has been part of Tesla's plans for a few years. Tesla Chairman Elon Musk earlier this month was quoted as saying that the goal is to produce a car priced in the $20,000 to $30,000 range, possibly in partnership with other automakers.
Nothing particularly new about Bluestar in the article. Interesting with all going on about the Roadster and the Model S that someone is writing an article about Bluestar though.
