Yeah, almost more of a show car or halo-vehicle for the coming GM electric platform. Likely to be priced over a quarter-million dollars, sold in tiny hand-made quantities. It might be good marketing move for GM but I don't see it as very relevant to Tesla or even most of Teslas competitors.
That said, parts of it are pretty, and at the price point they can give it a lot of range by simply using an enormous battery pack ala Hummer.
