2025 GMC Sierra 2500HD Denali: Price, consumption, picture, technical data.
The GMC Sierra 2500HD Denali, a popular choice among heavy-duty truck buyers, is receiving a refresh for the 2025 model year. While details remain limited, GMC has revealed a few key updates that enhance the truck’s styling and performance.
Exterior Updates and Design
The most noticeable change to the Sierra 2500HD Denali’s exterior is the addition of a functional hood scoop. This scoop not only adds a touch of aggression to the truck’s appearance but also hints at potential powertrain enhancements.
The Denali trim retains its signature chrome accents, including the prominent grille, large wheels, tow mirrors, and side steps. The overall design remains bold and imposing, reflecting the truck’s heavy-duty capabilities.
Interior Changes
While images of the updated interior haven’t been released, GMC is expected to make subtle refinements to the Sierra 2500HD Denali’s cabin. Higher quality materials and updated technology features are likely, enhancing the truck’s premium feel and overall comfort.
Powertrain and Performance
The Sierra 2500HD Denali is expected to carry over its current powertrain options, including a 6.0-liter V8 gasoline engine and a 6.6-liter Duramax turbodiesel V8. However, there are rumors that the Duramax engine may receive an update for improved power and torque output.
Currently, the 6.0-liter V8 produces 360 horsepower and 380 lb-ft of torque, while the 6.6-liter Duramax delivers 397 horsepower and 765 lb-ft of torque. The Duramax engine is known for its impressive towing capabilities, and any power increase would further solidify its position as a leader in the segment.
