The GMC Sierra 2500 HD has been building on the very popular GMC Sierra 1500 full-size pickup and raising the capability levels to an even higher level. For 2024, the GMC Sierra 2500 HD is topping itself, raising its game from the 2023 model to specs and capabilities that are even greater. The GMC Sierra 2500 for 2024 has bumped up the horsepower and torque in the available turbodiesel engine and nearly doubled the maximum towing capacity.
If you liked the GMC Sierra 2500 HD’s performance and power in 2023, you’re going to like it even more in the 2024 model. Here’s a look at the upgrades that have been made in the new 2024 GMC Sierra 2500 HD that’s available right now at Navarre GMC in Lake Charles LA.
2024 upgrades in performance and power
The 2023 GMC Sierra 2500 HD offered an available 6.6-liter Duramax® turbodiesel V8 engine and that continues to be true for the 2024 model. The even better news is that GMC has upgraded that engine, raising it from 445 horsepower in 2023 to 470 horsepower for 2024. The amount of torque has also been increased from 910 pound-feet in 2023 to 970 pound-feet in 2024.
Most impressively of all, GMC has accomplished the seemingly impossible task of almost doubling the turbodiesel’s maximum towing capacity from a formidable 18,500 pounds up to a mind-boggling 36,000 pounds. And instead of offering a six- and 10-speed automatic transmission, truck buyers from Sulphur LA and Orange TX will be getting the excellence of an Allison® 10-speed automatic transmission on every model.
More exciting detail on the increased power in the 2024 Sierra 2500 HD
The 6.6-liter V8 diesel engine in the 2024 Sierra 2500 HD now comes standard on most models and it’s teamed up with the superb Allison® 10 speed automatic transmission. This combination allows the engine to operate closer to its optimum power range, giving you a maximum amount of performance, torque and efficiency.
The new Sierra 2500 heavy-duty truck comes with the most comprehensive trailering-assistance technology in its class. It gives truck drivers from Moss Bluff and Jennings, LA better views and more confidence when you’re towing. The hitching and towing process has been streamlined and your sense of visibility, safety and confidence will be significantly enhanced.
A high-level look at 2024 trim levels
The new 2024 GMC Sierra 2500 HD gives you a lot of value in the entry-level Pro trim including a standard 6.6-liter V8 gas engine and the best heavy duty cargo bed volume in its class. The HD trim comes with your choice of a 6.6-liter V8 gas engine or an available 6.6-liter Duramax® turbodiesel along with a standard 13.4-inch touch screen. The SLT trim gives you available 10-way power-adjustable front seats with perforated leather appointments. The rugged AT4 model comes with off-road suspension and skid plates.
In the 2023 lineup, the GMC Sierra 2500 HD offered the upscale Denali as the highest trim level, giving you authentic open-pore woods, patterned aluminum trim and forged perforated leather seating surfaces. For 2024, the GMC Sierra 2500 now gives you the option of even more luxury in the all-new Denali Ultimate trim.
