Looks like GMC has something cooking for May 15th!

The teaser clip shows a few interesting changes. One thing that stands out is a redesigned interior control dial ā could be a hint at a cabin refresh. What really caught my eye was the Hummer EV SUV doing an insanely tight donut. The front inside wheel barely moves, which suggests some kind of upgrade to the powertrain controls or maybe a new off-road mode.
