According to the MotorsTV website it says you can watch the series on MotorsTV this season, but thats about as much info as I could find. Grand Am had a a major pressance on the MotorsTV stand at the Autosport show, with Crown Royal sponsored car on display and they were handing out a fans guide to Grand Am leaflets on the stand.
So I would guess yes that they are taking whatever Speed are showing I would think.
