What’s new for 2021?

As we already mentioned, the number of changes for the next year seems pretty solid and it’s mostly about new standard features. One of the things that come to mind is a new power-retractable assist step with LED perimeter lighting, which is a part of the new Black Diamond Edition package. This package also includes goodies like Auxiliary Trailer Camera, MultiPro Audio System by Kicker, Front floor liners with removable carpet insert, Rear floor liners with removable carpet insert, Trailer tire pressure monitor sensors, Power-retractable assist steps with LED perimeter lighting and 20-inch high gloss Black painted aluminum wheels.

Speaking of the wheels, the company has prepared a whole bunch of new rims, which will be available not just in Denali, but in other trim levels as well.  If names mean something to you, here they are: 20-inch high gloss black-painted aluminum, 20-inch Black Transit wheels, 20-inch high gloss Black aluminum wheels with machined inserts, and 20-inch multi-dimensional Chrome.

Another interesting novelty for the next year is the addition of a new set of available premium front or rear floor liners with removable carper inserts. This feature is optional.

Essentially, we will see the identical model as for the current year, which is characterized by several upgrades compared to the standard model.

When it comes to powertrain, we won’t see changes. So, 2021 GMC Sierra 2500 Denali will carry on with two familiar engine options. Base models come with a 6.6-liter  V8 gasoline engine, which puts out around 401 horsepower and 464 pound-feet of torque. It comes in pair with a 6-speed automatic transmission and provides quite solid performances. However, most drivers would rather pick a well-known 6.6-liter Duramax turbodiesel. This one puts out around 445 horsepower and 910 pound-feet of torque, which is superior, both in terms of towing and fuel economy. Also, this engine comes in pair with a new 10-speed automatic transmission.
