Performance


The 2026 GMC Sierra 1500 delivers strong, efficient performance for everyday driving and lighter towing and hauling duties around Cumberland.

For maximum power, the available 6.2-liter V8 cranks out an impressive 420 horsepower and 460 lb.-ft of torque, making it one of the most potent engines in its class.

For bigger jobs, the 2026 GMC Sierra 2500 HD brings some serious muscle with two powerful engine choices. The standard 6.6-liter V8 gas engine generates a best-in-class 401 horsepower and 464 lb.-ft of torque, providing ample power for heavy-duty towing and hauling. And for maximum towing and hauling power, the available Duramax 6.6-liter turbodiesel V8 delivers a stunning 445 horsepower and 910 lb.-ft of torque, making it one of the most capable engines in the heavy-duty truck segment. Those in Frostburg needing a job site with heavy-duty capability or those on the farm will love what the Sierra 2500 HD offers.

Both the 2026 GMC Sierra 1500 and Sierra 2500 HD are towing and hauling standouts, but the HD takes things to the next level. The Sierra 1500 can tow up to 12,500 pounds when properly equipped, with a max payload capacity of 2,280 pounds.
