2023 GMC Sierra HD

The 2023 Sierra HD lineup features five trim levels. Each showcases substantial pickup truck proportions and flowing lines, creating an elegant yet aggressive silhouette. With the Pro, you can take advantage of LED headlights, taillights, and daytime running lights. You can also equip the Pro with the world's first six-function MultiPro tailgate, which comes standard on the SLE. The SLE also features 17-inch machined aluminum wheels, while the SLT gets 18-inch machined aluminum wheels with Dark Gray Metallic Accents. If you go with the AT4, you can equip your Sierra HD with 20-inch high-gloss black aluminum wheels and an X31 Off-Road Package that includes twin-tube Rancho shocks and skid plates. Finally, there's the Denali, which sits atop 20-inch polished aluminum wheels with a distinctive multidimensional design. All trim levels are available as a Sierra 2500 or Sierra 3500.

As a heavy-duty pickup truck, the 2023 Sierra HD gives you incredible power. The base engine is a 6.6-liter gas V-8 capable of producing 410 horsepower and 464 pound-feet of torque. GMC also offers a 6.6-liter Duramax turbo-diesel V-8 that generates 445 horsepower and 910 pound-feet of torque. The Sierra 2500 models have a maximum towing capacity of 18,500 pounds, while Sierra 3500 models can tow up to 36,000 pounds.

No matter where you're going, you can count on your Sierra HD to deliver exceptional performance. GMC pairs the gas V-8 with a six-speed automatic transmission, while the turbo-diesel engine teams up with an Allison 10-speed automatic transmission. Both systems optimize engine output while enabling the Sierra HD to accelerate smoothly and handle effortlessly. The Sierra HD's responsive suspension minimizes noise and road impact to give you a more comfortable ride, whether you're maneuvering through traffic or tackling tight trails.

The 2023 Sierra HD comes with your choice of a regular cab that seats three, a double cab that seats six, or a crew cab that seats six. The crew cab offers best-in-class headroom and legroom and a rear-folding split bench with under-seat storage, while every cabin in the Sierra HD lineup features premium seating surfaces and stylish accents. You can also take advantage of Apple CarPlay and Android Auto integration to stream music, get traffic updates, and make hands-free phone calls.

The 2023 GMC Sierra HD wouldn't be complete without its advanced safety features. These include a Teen Driver system that encourages safe driving habits, allows parents to set limits when their teen is operating the vehicle, and provides in-vehicle report cards. The Sierra HD also offers a lane-departure warning, front and rear parking assistance, and automatic emergency braking.
