Maybe you want more than a great-value truck. Maybe you want the most luxurious heavy-duty truck there is. In that case, upgrade either 2021 GMC Sierra HD truck to the Denali trim. The Denali is named for North America's largest peak, a majestic height that few can access and even fewer can traverse. Taking inspiration from this natural wonder, GMC has built the 2021 Sierra HD Denali to perfectly balance strength and beauty.
The Denali model is a significant upgrade that improves on the base models' exterior, interior, built-in technology, and more. It's the pinnacle of truck engineering, starting with its excellent engines: a 6.6L V-8 gas engine with an electronically-controlled automatic transmission or a 6.6L Duramax Turbo-Diesel V-8 paired to a 10-speed Allison automatic transmission. Enhanced brakes and a high-strength chassis improve the 2021 Sierra HD's performance while carrying heavy loads.
As for the interior, upscale details and technology create a luxurious experience; drive in style while your truck does all the hard work you need to accomplish. Enjoy a premium cabin with elegant open-pore ash wood and brush aluminum accents, additional interior color options, Forge perforated leather seats, a power sunroof, and more. Meanwhile, an optional Head Up display helps you monitor your drive without taking your eyes off the road.
Take advantage of the MultiPro tailgate, which comes standard with the Denali edition of the latest Sierra HD trucks. With this revolutionary tailgate technology, you can shift the truck's tailgate into various formations, including a step ladder, workbench, and flatbed. Its carbon-fiber-reinforced paneling is durable and tough, too, so it can handle some rough treatment and still come out looking sharp.
The Denali edition of the 2021 Sierra HD also makes towing and transporting cargo even easier, thanks to its advanced camera technology. Features include 360-degree views, truck bed views, and even a "transparent" option that allows you to "see through" your trailer to view what's behind you. Multiple other camera views make safe driving easy from the highway to the job site so that you can transport your goods, equipment, another vehicle, or even just yourself and your family with ultimate peace of mind.
Add to that the advanced safety technology features like blind-spot monitoring, forward-collision warning, lane-departure warning, and rear cross-traffic alert, and you have one of the safest trucks around. Make no mistake: the Denali may have elegant looks, but it's still one of the toughest trucks on the market. The Sierra Denali HD works just as hard as any other 2021 GMC Sierra 2500 or 3500 - it just looks good doing it and treats its passengers to a luxury car level of comfort.
