New paint color choices, including Coastal Dune and Redwood Tintcoat, add visual interest and customization potential. Meanwhile, practical touches like active air shutters and standard spray-on bedliners (now included on SLT, AT4, Denali, and AT4X) enhance both performance and durability. The popular MultiPro™ Tailgate remains a centerpiece of the Sierra’s design, now standard on more trim levels including Elevation and SLE.

Upper trims like Denali and Denali Ultimate elevate the cabin with genuine wood or aluminum trim, refined leather seating, and upgraded sound insulation for a quieter ride.
