The 2023 GMC Sierra 3500 HD is the go-to one-ton pickup for those who want a heavy-duty truck that cuts no corners and comes jam-packed with luxury, comfort, and utility features. This truck is designed to accommodate not only those who need a heavy-duty workhorse that can manage tremendous loads but also drivers who want a ride that stands out as a high-quality vehicle with amazing features both inside and out.
The 2023 model carries over all of the great features from the most recent model years, including a range of nine exciting exterior colors. These range from grayscale tones like Summit White, White Frost Tricoat, Quicksilver Metallic, Ebony Twilight Metallic, and Onyx Black to eye-catching hues like Cayenne Red Tintcoat, Pacific Blue Metallic, Cardinal Red, and Forest Metallic. All of the new features from the 2021 model year refresh also carry over to the 2023 model, including improved trailering capacity, new content packages, standardization of the MultiPro Tailgate, and enhanced trailering technologies.
You can get the 2023 GMC Sierra 3500 HD in five distinct trims, each designed for a different type of diver. There is the base Pro trim for hard workers, the mid-grade SLE and SLT to add a few more features, the off-road AT4 trim, and the Denali trim for those who value luxury above all else. The available customization, trim configurations, and packages give the 2023 GMC Sierra 3500 HD a lot of variety and breadth for those who want a heavy-duty pickup for multiple purposes.
A one-ton truck needs the best that the industry has to offer when it comes to performance. Why? Because truck shoppers expect these heavy-duty pickups to offer payload and trailering ratings sufficient to handle the toughest jobs out there. Fortunately, GMC is certainly one of the top brands in the full-size pickup arena, and the Sierra 3500 HD is the cream of the crop in the GMC lineup.
The 2023 Sierra 3500 HD is powered by two distinct powertrain options that are known for getting the job done at all costs. These include the standard 6.6-liter gasoline V8, which outputs 401 hp and 464 lb-ft of torque and is paired with a six-speed automatic transmission. If you need more power than what the gasoline V8 has to offer, a more powerful 6.6-liter Duramax turbo-diesel V8 is available, which outputs 445 hp and 910 lb-ft of torque. The Duramax is paired with a durable Allison 10-speed automatic transmission, which can be equipped with a power take-off for added versatility.
The 2023 Sierra 3500 HD comes in both rear-wheel drive and four-wheel drive, depending on what you need the truck for. The available two-speed Autotrac transfer case makes it easy to quickly and efficiently switch driving modes for the four-wheel drive model and features four distinct options: 2Hi, 4Hi, 4Lo, and Auto. Also, unlike the three-quarter-ton Sierra 2500 HD, you can get the Sierra 3500 HD with dual rear wheels for when you need to manage those extra heavy loads. With an available 220-amp alternator, four-wheel anti-lock disc brakes, and automatic locking rear differential, this truck is ready for anything.
Added features like a diesel exhaust brake and digital variable steering assist also help alleviate some of the strain and rigor involved with maneuvering such a large truck on the road. This means you have less to worry about and can focus more on getting to your destination rather than fighting with the vehicle. Added bonuses to the Sierra 3500 HD's performance suite include a heavy-duty battery, a heavy-duty air filter, and an integrated trailer brake controller.
Trucks the size of the 2023 GMC Sierra 3500 HD are expected to be more than capable of handling just about any job. The good news is that the Sierra 3500 HD does not disappoint when it comes to its capabilities, providing more than enough performance for trailering lots of cargo with relative ease. This is thanks to a durable frame and reinforced suspension capable of trailering tens of thousands of pounds.
The 2023 Sierra 3500 HD can trailer a maximum of 36,000 lbs when configured as a diesel dually with a gooseneck hitch. With the gasoline engine, the Sierra 3500 HD can tow up to 17,200 lbs. You can also choose between the two different bed sizes, which include a standard or a long bed, giving you access to a max payload capacity of 7,442 lbs when configured with dual rear wheels and the gasoline V8 engine. If you opt for the diesel instead, don't worry––this truck can still haul up to 6,523 lbs of payload.
With available bed assist steps and the MultiPro Tailgate, you have easy access to your cargo. In fact, the MultiPro Tailgate provides you with six different ways to utilize the Sierra 3500 HD for your workday needs. This includes using it as a primary gate, a primary gate load stop, an inner gate load stop, a full-width step to get into the bed, and an inner gate work surface. The MultiPro Tailgate is also available with an external multi-speaker setup for a complete outdoor audio experience.
Tack on features like the available power-adjustable vertical trailering mirrors with auto-dimming, cargo tie-downs for the bed, or available IntelliBeam automatic LED high beams, and you have a high-quality, fully robust truck available to tackle any kind of weather or lighting conditions. With the added addition of trim-specific features like a power sunroof and interior comfort features like 10-way power-adjustable driver and front passenger seats with lumbar support or available perforated leather seating, you have an incredible work truck with unrivaled luxury qualities. All of these features help improve the driving experience within the Sierra 3500 HD tenfold.
The combination of a tech-rich cabin with advanced trailering features is always welcome for a one-ton pickup where trailering or hauling multiple tons of cargo is a daily occurrence. Safety and stability are top priorities in those kinds of situations, just the same as comfort and convenience are cherished by those who find themselves frequently making long hauls across large stretches of highway. The 2023 GMC Sierra 3500 HD is one of those heavy-duty pickup trucks that manages to strike that balance between accessibility and functionality in equal measure.
A complete assortment of driver-assist features is available in the robust GMC safety suite, which can be further enhanced with the available GMC and OnStar Connected Services plan. The plan includes connectivity for apps, remote access to your vehicle, Wi-Fi hotspot data, and more. There's also the added bonus of automatic crash response and roadside assistance. For those doing a lot of trailering and towing, you have the standard inclusion of hitch guidance for conveniently hitching a trailer to the truck. Available features like the in-vehicle trailering app, HD Surround Vision with multiple trailer view cameras, and hitch guidance with hitch view all help make the trailering process so much easier than ever before.
Even on the infotainment front, you have a healthy mix of practical functions with entertainment features. An eight-inch HD touchscreen is offered with a built-in navigation system, and this comes with Bluetooth wireless support, enabling hands-free phone calls and text messaging without taking your hands off the steering wheel or your eyes off the road. Added features like wireless Apple CarPlay and Android Auto, as well as the availability of SiriusXM 360L, help add value and fun to the overall line-up of the 2023 GMC Sierra 3500 HD's suite of technology.
