The power war among heavy-duty pickups looks to continue.

Competition in the American pickup truck market remains fierce. Ford, Ram, and General Motors' combined forces from Chevrolet and GMC are constantly trying to find an edge in the ruthless segment. GMC is now revealing its latest advance in the arms race by showing the new, chrome-outlined hood scoop for the 2017 Sierra Denali 2500HD. The upgrade hints at even more muscle for hauling, too.

GMC’s enigmatic announcement simply says the 2017 model year truck has “a functional hood scoop design hinting at what is beneath its bold new appearance.” The photos of the nose job offer more details. For example, the shots clearly show the Duramax badge on the hood, which means this pickup is a diesel. The current 6.6-liter diesel V8 in the Sierra 2500HD Denali makes 397 horsepower and 765 pound-feet of torque, but the addition of extra airflow could push the output even further.

To beat its heavy-duty, diesel competitors, the updated Duramax needs to put up big numbers. The 6.7-liter inline-six in the Ram 2500HD produces up to 370 horsepower and 800 pound-feet of torque. Meanwhile, the current Ford Super Duty offers up to 440 hp and 860 lb-ft from its 6.7-liter V8, and a new model is on the way for the 2017 model year, which could have even more.
