Video of the Week: 2021 GMC Yukon AT4 Overland Test

2021 GMC Yukon AT4 test drive

This video of the week comes straight from the Expedition Portal YouTube channel (subscribe here), where Scott Brady tests the 2021 GMC Yukon AT4 on the red rock trails of Sedona, Arizona. If you are unfamiliar with the most recent version of the Yukon, you may want to read this article first: 2021 GMC Yukon has serious off-road potential.

Aside from some technical limitations (mostly due to its size), the overall results were positive. Scott gives a nod to many elements of the AT4 edition of this vehicle, including its substantial 1,700-pound payload, 2-speed transfer case, 32-degree angle of approach, adjustable airbag suspension, more aggressive traction control, and highway comfort to name a few.
