The 2025 GMC Denali HD is a heavy-duty pickup truck that is set to be released in 2024. It is the successor to the current Denali HD, which was first introduced in 2001. The 2025 Denali HD is expected to be a major upgrade over the current model, with a number of new features and improvements.
One of the most significant changes to the 2025 Denali HD is its new exterior design. The truck has a more aggressive and modern look, with a new grille, headlights, and bumpers. The interior of the truck has also been redesigned, with a new dashboard, center console, and seats. The 2025 Denali HD is also expected to be more powerful and efficient than the current model. It will be powered by a new 6.6-liter turbodiesel V8 engine that produces 450 horsepower and 910 lb-ft of torque. The engine will be mated to a new 10-speed automatic transmission.
