Moreover, leather-wrapped door panels, steering wheel, and A- and B-pillar handles further elevate the cabin experience.
For 2024, GMC has incorporated cutting-edge trailering technologies like the Transparent Trailer View, which now extends compatibility to gooseneck and fifth-wheel trailering. With the introduction of the AT4X off-road trim and the AEV Edition - offering steel bumpers, AEV 18-inch wheels, and sturdy skid plates - GMC ensures that the Sierra HD caters to various trucking needs.
The infotainment system is noteworthy, featuring a massive 13.4-inch touchscreen that supports wireless Apple CarPlay and Android Auto, standard on the Denali and Denali Ultimate trims. Safety remains a priority with the addition of numerous driver-assistance features, cementing the Sierra HD's position as a balanced blend of strength and elegance in the truck world.
