The 2026 Silverado HD offers two proven powerplants. The standard 6.6L V8 gas engine delivers dependable strength for everyday tasks. For maximum capability, the available Duramax(R) 6.6L Turbo-Diesel V8 produces up to 470 horsepower and 970 lb-ft of torque-giving you serious pulling power for heavy hauling and towing.

Both engines pair with a 10-speed Allison(R) automatic transmission for smooth gear transitions and optimal performance under load. Whether you choose gas or diesel, you'll get consistent, reliable strength engineered to handle demanding workloads with ease.
