Tesla Model X
In addition to admitting that it has yet to complete a Model 3 alpha prototype, Tesla's latest SEC filing outlines Model X progress.
According to the filing, Tesla has completed both an alpha and beta prototype of the Model X. These are two of the three completions that Elon Musk needs in order to qualify for an equity grant from Tesla. The third item that must move to completion is production of the Model X.
It's widely believed that, despite previous delays, the Model X will arrive in mid 2015, though we suspect the X will be in very limited production until well into 2016.
For those interested in the Model X, the long waiting list, coupled with low initial production, means that if you sign up for one today, there's almost no chance you'll take delivery until mid or late 2016.
