2023 GMC Sierra 2500: Redesign, Price, and Release Date. Hummer is the truck under the spotlights when speaking about the GMC lineup. The brand delivers a few more interesting models that belong to the top of the class vehicles. The 2023 GMC Sierra 2500 is going to offer a mighty Duramax engine with plenty of torque. Engineers combine it with an updated Allison transmission. Additional options can make the truck capable for an off-road drive. On the other hand, if you are a fan of premium equipment and options, the Denali package is also there in the heavy-duty segment. The downside is the price, which can go up pretty rapidly.
Plenty of options will make the build very fun. The truck is available with dual- or crew cab configurations. Long or standard bed can be paired with these cabin options. We already mentioned a mighty oil burner. But, there is also a petrol powerplant. AT4 is an off-road package, Denali makes this offer premium, and you can still pick some of the lower trim levels, such as SLT, SLE, or the entry-model Sierra. Of course, two- and four-wheel drive are also available.
2023 GMC Sierra 2500 Specs, Towing Capacity
The 2023 GMC Sierra 2500 is not going to offer a dually setup. It means you need a Series 3 truck, Sierra 3500, to achieve a maximum towing capacity of 36,000 pounds. Still, the Series 2 model will be pretty capable. You can pick either a petrol or a diesel engine. A more affordable variant is a 6.6-liter gasoline V8, paired with a six-speed transmission. The engine is going to crack out 400 hp and 464 lb-ft.
True truckers will definitely be after a diesel setup. A 6.6-liter turbodiesel is good for 445 hp and 910 lb-ft of twist. Just for an example, its rivals, Ram 2500 and Ford F-250 are out with 1,000+ lb-ft of torque. Still, that doesn’t affect the overall performance, since all three trucks are at the same level. Allison transmission is something that will make a difference. Even Ram HD trucks might adopt it and replace a slow and old AISIN gearbox. When you combine a 6.6-liter V8 diesel with AT4 off-road package, there is no obstacle that will stop you.
2023 GMC Sierra 2500 AT4 vs Denali
The entry-level version of the Sierra HD truck is supporting Apple CarPlay and Android Auto. A 7-inch screen is the center of the multimedia system. Traction control and hill start assist are parts of the standard offer. The SLE is adding a leather steering wheel and MultiPro tailgate. ProGrade trailering system is another top of the class feature that is available for the HD truck.
The SLT is already a nearly premium offer. Larger wheels are included, as well as a bigger infotainment screen and premium GMC multimedia system. A lot of driver aid features are also there. Still, the top of the class versions are AT4 and Denali. It depends what you need from your truck to make a choice. The first one is the off-road package (abbreviation from All-Terrain 4 × 4). Special shocks, suspension, skid plates, bedliner, and other stuff to make a more comfortable ride off the road are there. On the other hand, the 2023 GMC Sierra 2500 Denali delivers luxury options, such as ventilated seats, Super Cruise system, Bose audio, etc.
