2021 GMC Sierra 2500: Bigger, not necessarily better

This heavy-duty pickup is immensely capable but it's not a truck most people would want to live with on a daily basis.

Craig Cole
Craig brought 15 years of automotive journalism experience to the Cars team. A lifelong resident of Michigan, he's as happy with a wrench or welding gun in hand as he is in front of the camera or behind a keyboard. When not hosting videos or cranking out features and reviews, he's probably out in the garage working on one of his project cars. He's fully restored a 1936 Ford V8 sedan and then turned to resurrecting another flathead-powered relic, a '51 Ford Crestliner. Craig has been a proud member of the Automotive Press Association (APA) and the Midwest Automotive Media Association (MAMA).

Nothing screams, "Get out of my way!" quite like a heavy-duty pickup truck.

No matter the model, the current-generation Sierra's interior is lackluster at best.

With a crew-cab body, this is a seriously big vehicle.

This crew-cab Sierra's rear seat offers miles of legroom and has nifty storage cubbies integrated into the backrests.

The GMC Sierra offers the most innovative tailgate in the pickup business. Seriously, it's amazing.

Under this truck's hood is a 6.6-liter gasoline V8 that delivers 401 horsepower and 464 pound-feet of torque.

That engine is smooth and sounds good, though it doesn't feel particularly potent.

The business end of this particular truck comes with a spray-in bedliner for maximum durability.

It's impossible to miss this truck's imposing grille.
