Styling-wise, Sierra AT4 models can be recognized thanks to the body color bumpers and grille surround, a
bolder grille finished in
black chrome, a high - gloss
black finish for the
window trim, mirror caps, and skid plate,
black chrome trim on the fog lamp bezels and fender, and red accents such as the vertical tow hooks.Inside, the off - road truck sports AT4 - specific darkened trim as well, leather seats with AT4 badging on the headrests, and all - weather floor mats.
For the exterior, they went
bold, opting for a striking combination of white and
black to accentuate the home's new architectural lines and many
windows.
