I guess it is now official. In recent interview (www.abclocal.go.com/kgo/story?section=global_warm&id=5399716) Elon says Tesla Roadster has 3.9s 0-60 time. I have enough respect for the men to expect him not to say something he is not sure about. Not in a TV interview and after they had to step back from 250 miles range to "over 200". I guess those PEM engineers keep on squizing more juice out of it.
