This is the upcoming all-new GMC Yukon in SLT and Denali trims undergoing testing, providing a first look at the SLT trim.
Up front is a grille different from the one seen on Denali, while the rear does not show any visible exhaust, unlike on the Denali. The rest of the model looks relatively identical to the Yukon Denali, which features a bright grille and visible quad-tip exhaust out back.
The new GMC Yukon will be revealed in early 2020 following the just-revealed Chevrolet Tahoe and Suburban.
