What’s New About The 2021 Chevrolet Silverado 2500HD

What Changes Has Chevrolet Made to Their Latest Silverado 2500HD?

The 2020 Chevrolet Silverado 2500HD was vastly different than the exiting 2019 model. It was basically an overhaul year, resulting in a new exterior, interior, and new technology never before seen in a heavy duty Chevrolet truck. It’s been a year since then however, and 2021 models will be hitting dealerships any day now. How does the 2021 Chevrolet Silverado 2500HD compare to 2020 models?

2021 Chevy Silverado 2500HD Performance Changes

Duramax Diesel Engine Changes?

2021 marks a year of refinement and improvement over the 2020 Silverado HD. The L5P Duramax diesel engine remains largely unchanged, but it still provides plenty of power at 445 horsepower and 910 lb-ft of torque. The 10-speed automatic Allison comes standard with the Diesel engine and it remains similar to the previous model year as well.

Changes to the 6.6L Standard Gas Engine

In 2020, the popular 6.0L V-8 engine was replaced with a new direct-injected 6.6L gas engine for huge performance gains and greater capability. The only major change for this 6.6L Gas engine in 2021 is that it now offers FlexFuel capabilities. Other than that, the powertrain is very similar. The same 6L90 6-speed Automatic transmission is used with a standard tow/haul mode.

Towing Improvements

Technology improvements on 2021 will definitely aid in towing now though. The Bed View Camera is now available on Work Truck, Custom, and LT models. The Safety Confidence Package is also available on Work Truck and Custom models.
