So it looks like the Hummer EV SUV will in fact NOT be debuting during Super Bowl 55 after all. Ad Age had reported a number of months back that GMC has purchased a 30 second ad spot to debut the SUV, but it turns out either that was false reporting, or GMC changed their mind, a la Coke and Pepsi this year.

GM Authority believes it to be the former, so it is still very likely that the SUV debuts in February, just not during the Super Bowl. I guess time will tell...and I'll try to keep everyone posted as soon as anything official comes out.
