Tesla Motors unveiled the Model S, its newest all-electric car, at a media event outside Los Angeles on Thursday afternoon. Billed as the first mass market highway-ready electric vehicle, the Model S can seat five adults and two children and can go for up to 300 miles on one charge. And, it costs a lot less than Tesla’s Roadster sports car, starting just shy of $50,000 (including a government tax credit). Check out our full story about the Model S unveiling here.
