I have not seen anything yet, but have heard Hummer will for sure be displayed at Motor Bella, and I assume the Texas State Fair since GM often brings new truck models to the fair. Outside of that, I do not think they have enough of them to start touring around yet? I expect to hear about Media drives in the next couple weeks, and if GM holds to patterns they will be embargoed until just before the Texas State Fair, and Motor Bella. I am watching twitter, as someone is bound to leak they got a media drive invite .
Another possibility, GM has already publicly stated they will be doing HummerEV media and investor drives as part of investor day event Oct 6-7 (Barra mentioned on the last earnings call she was looking forward to this) I am sure GM will have some public launch (final specs, range, etc...) of the HummerEV before they tour it around to dealerships, or have us formalizing orders.
