The 2026 Chevrolet Silverado HD offers two powerful engine choices. The available Duramax 6.6L Turbo-Diesel V8 produces up to 470 horsepower and 970 lb-ft of torque, paired with a smooth 10-speed Allison automatic transmission. The standard 6.6L V8 gas engine provides dependable strength for everyday hauling.

Both powerplants are engineered for consistent performance under load. The diesel option excels if you're tackling heavy, frequent towing or commercial work. The gas engine delivers solid capability for lighter-duty tasks. The transmission automatically optimizes gear shifts for smooth transitions whether you're on the highway or at the job site.
