The 2026 Chevrolet Silverado 2500 HD is engineered for drivers who demand maximum performance from their heavy-duty truck. At the top of the powertrain lineup sits the legendary 6.6-liter Duramax Turbo Diesel V8 engine, generating a remarkable 470 horsepower and 975 lb-ft of torque — providing tremendous pulling power for trailers, equipment, and heavy payloads across Central Texas highways and worksites. Paired with an Allison 10-speed automatic transmission, this powertrain delivers smooth, controlled power delivery under any load condition.

For drivers preferring a gasoline option, the standard 6.6-liter V8 gasoline engine produces 401 horsepower and 464 lb-ft of torque. It is important to note that official EPA fuel economy estimates for the 2026 Chevrolet Silverado 2500 HD have not yet been released by the manufacturer. When those ratings are published, Kramer Chevrolet Madisonville will update this information accordingly. Maximum conventional towing capacity reaches 18,500 pounds when properly equipped — among the best in the segment.
