Both are quite versatile and work for a variety of uses, whether recreational such as camping, or professional such as delivery and construction.

Choosing the 2023 GMC Sierra 2500 HD vs. the 2023 Ram 2500 isn’t an easy choice, but looking at both in detail may make the decision easier.

Function and Power

The base-model 2023 GMC Sierra 2500 HD comes standard with 6.6L V8 engine outputting a whopping 401 horsepower and 464 lb-ft of torque. It justifiably earns a reputation as one of the workhorses of the truck market, as the beastly strength of the engine accelerates smoothly, towing heavier payloads and climbing steeper inclines steeper with greater ease than many competitors. The 2023 GMC Sierra 2500 also has an available 6.6L Duramax Turbo-Diesel V8 engine. If a buyer chooses this option, they will be rewarded with an output of 445 horsepower and an astounding 910 lb-ft of torque.

One can’t forget the sheer strength of the 2023 Ram 2500 as well. It boasts a base model powered by a standard 6.4L V8 engine that offers 410 horsepower and 429 lb-ft of torque. It also offers an optional diesel engine, an inline-6 Cummins Turbo-Diesel making 370 horsepower and 850 lb-ft of torque. This makes the 2023 Ram 2500 a perfect fit for those seeking to tow especially heavy loads or fill the bed with especially large cargo.

One could conclude that the Sierra 2500 HD and the Ram 2500 have similar horsepower in their base models, leaning slightly in the Ram 2500’s favor. In the torque department, however, the 2023 GMC Sierra 2500 is a standout by leaps and bounds. Its standard engine already outperforms the Ram, but the 6.6L Duramax Turbo-Diesel V8 leaves Ram’s six-cylinder engine behind. Thus, if one is looking to climb steep terrain or tow at heavy capacity, it is worth considering the Sierra 2500.
