Exterior & Interior
The 2027 Sierra 2500HD gives off an air of refined toughness from the outside. Its 20-inch wheels are available in two styles: polished metal and off-road-ready matte, and they’re robust and stylish.

Along with heated and ventilated seats, a 14-speaker Bose sound system, and a fully adjustable digital driver display, the interior is designed to provide you complete control over all of the car settings.
Enhanced aerodynamics are a feature of this model, which is seen in the incorporation of understated yet functional air curtains into the front fascia. Modernized materials and reinforcements allow the bed to support greater weight, while enhanced tie-down points allow for safer cargo securing. The 2500HD is now more fashionable and versatile than ever with new color options including Deep Granite Metallic and Summit White Pearl. Whether you’re on the go or at the work site, it will turn heads.
