2023 GMC Sierra 2500 HD LaGrange

In a super-sized variety, the 2023 GMC Sierra Heavy Duty (HD) pickup trucks offer us everything we love about the half-ton variant. When it comes to luxury, these trucks go all the way up to the Denali level. These trucks come with a variety of engine, cab, and trim options.

What’s new in the 2023 GMC Sierra 2500 HD?

These pickups have imposing looks, large, angular wheel openings, and large beds with lots of steps for comparatively simple access. The range of trim levels includes everything from functional Pro work trucks to opulent Denali variants.

The base V-8 engine is adequate for simpler tasks, but you’re probably searching for a heavy-duty truck because of the optional turbodiesel’s 910 lb-ft of torque. The Sierra 3500HD has a carrying capacity of up to 35,000 lbs. Most places will need a special driver’s license for that, but suffice it to say that these trucks won’t pay much attention to a camper or a vehicle trailer. But when they fall approaching empty, their fuel gauges will notice.

They haul in comfort, helping to cover up the drab dash design with their comfortable seats and generous space. The 8.0-inch touchscreen at least features a clear user interface and supports wireless smartphone connectivity.

Automatic emergency braking is an optional function that should be added to higher trim levels that provide it. Unfortunately, the government and the insurance industry cannot grade these trucks for either fuel efficiency or safety due to their size.

Engine, Transmission, and Performance

Although the 2023 GMC Sierra HD is surprisingly agile on the road, it is its towing prowess that earns it a 6 out of 10 on the TCC scale.

Heavy transporters will want to spend more money for the turbodiesel because of its 445 hp and—get this—910 lb-ft of torque. Even the regular 6.6-liter V-8’s 401 hp and 464 lb-ft of torque are nothing to sneeze at. Additionally, turbo diesels upgrade their automatic transmission from 6-speed to 10-speed.

Depending on the arrangement, a dually’s payload is limited to 7,400 pounds, and its maximum trailer towing capacity is 35,000 pounds when equipped with an optional fifth-wheel system.

Towing and Payload Capacity

The GMC Sierra 2500HD Pro has a towing capacity of 18,000 pounds with a Duramax diesel engine and 14,500 pounds with a gasoline engine. This three-quarter-ton truck can carry 3,614 pounds of payload with a diesel engine and 3,900 pounds with a gas engine.

Fuel Economy and Real-World MPG

The power needed for these Sierra pickup trucks is provided by two engines. They are not subject to EPA fuel mileage ratings because of their size.

Interior, Comfort, and Cargo

This enormous GMC vehicle provides the comfort and composure required for driving while still driving like a big truck. A work crew can fit comfortably within a double cab, but a crew cab offers a little more space for everyone to spread out. More high-end features are added to this truck as you move up the trim levels.

Infotainment and Connectivity

With its offered cutting-edge safety and driver assistance features as well as cutting-edge innovations, the 2023 GMC Sierra Heavy Duty pickup offers a fantastic driving experience.

Safety and Driver-Assistance Features

Most trim levels require two additional packages to enable automatic emergency braking. Not even the top-of-the-line Denali comes standard with it. Furthermore, automatic emergency braking is not even an option on the base Sierra Pro. However, GMC provides more than a dozen camera perspectives, which makes parking this beast very simple.

Interior Design

Advanced, strategically placed technology is available in the elegant and roomy cabin to help ensure a comfortable, intelligent trip.

• Available heated steering wheel
• Available heated and ventilated front leather-appointed seats
• Available HVAC system with dual-zone climate control and rear-seat outlets
• The elevated driver seat provides soft cushioning for improved support during lengthy drives and allows you to confidently survey the road.
• With best-in-class Crew Cab front head and leg room (43.1″), the cabin is spacious (44.5″)
