Actually, seesaw mentioned that one of the drivers refers to an AWD model. Not that the car actually IS an AWD model. If what you're saying is in fact true, that they were driving an AWD model...then yes, that's confirmation enough. That's not what Seesaw said in his post, though.
Over the years of Tesla ownership I have heard a lot of things mentioned that have never been confirmed! Sounds like there is some video that I haven't seen that makes it clear, though.
