The 2026 Silverado HD gives you two powerful engine choices:

**6.6L V8 Gas Engine:** A dependable standard option delivering solid strength for everyday hauling and lighter towing tasks.

**Duramax 6.6L Turbo-Diesel V8 (Available):** This premium option produces up to 470 horsepower and 970 lb-ft of torque-the power you need for heavy-duty work and maximum towing capacity (up to 36,000 lbs on the 3500 HD). It pairs with a 10-speed Allison automatic transmission for smooth, optimized performance under load.

**Which is right for you?** If you're doing heavy hauling, commercial work, or maximum towing, the diesel delivers the muscle. For everyday tasks, the gas engine provides reliable capability at a lower price point.
