The 2018 Sierra HD goes all in on premium. The trucks do it with quiet, refined interiors that put you in command of an available 6.6L Duramax Turbo Diesel engine—our most powerful ever—for robust hauling and trailering. They’re the latest reminders that the same passion and purpose that drive you also drive us. We set our own standards and prove that Professional Grade isn’t merely a label, it’s a way of life. Sierra HD is the latest example of how we take a strong stance for what we believe in and pursue it like a pro.
Sierra HD gets its heavy-duty power from a proven source, the available Duramax 6.6L V-8 Turbo Diesel with 910 lb-ft of torque and 445 hp under your right foot. Prefer your power gasoline-fueled? Sierra HD comes standard with the force and efficiency of our 360-hp Vortec 6.0L V-8.
GMC engineers love challenges. Sierra HD offers a steering system smart enough to tailor its response to your unique driving situation, in real time. Available Digital Steering Assist senses speed (especially important when trailering) to enable ease of handling at low speeds and improved steering feel at highway speeds. It also changes when the Tow/Haul button is activated, providing additional assist at reduced speeds and less at highway cruising speeds.
We believe that it’s not just how much you tow, it’s how well you tow that matters. That’s why Sierra HD’s available Duramax Diesel combined with seamlessly integrated trailering technologies generate the confidence to control heavy loads, especially in challenging situations. Because we’re not only building heavy-duty trailering machines, we’re building confidence in those who drive them.
Information gives us power. That’s why Sierra HD positions information where it’s easy to read at a glance (gauges are LED back-lit for enhanced night viewing) and controls are within reach. Sierra also offers advanced technologies to keep you connected, informed and in control of your surroundings.
