The 2021 GMC Sierra 1500 aims to stand out in the highly competitive field of full-size pickup trucks, but the results are a mixed bag. Along with being undeniably handsome, the GMC can be equipped with a carbon-fiber cargo bed and a multi-function tailgate. It also offers a 420-hp 6.2-liter V-8, which is the largest among half-ton trucks not called the Chevy Silverado 1500, and among the myriad engine options on the roster. The lineup is headlined by the popular Denali model and an off-road-oriented AT4 trim. While they look great in the valet lane or out on the trail, the Denali's interior doesn't live up to its luxury billing, and the AT4 can't compare to the Ford F-150 Raptor or the Ram 1500 TRX. Instead, the 2021 Sierra 1500 is a stylish and capable option that lacks the refinement and excitement of some full-size rivals.
What's New for 2021?
For 2021, GMC gifts the Sierra 1500 with several new or enhanced trailer-assistance features. The latter is highlighted by a jack-knife alert that does what its name suggests and a trailer-length indicator that lets the driver know when nearby traffic might interfere with a connected trailer. Likewise, the Sierra's Multipro tailgate now enjoys wider availability, there are more paint options, and the AT4 model adds new Goodyear Wrangler Territory tires and a high-clearance step. The optional diesel engine also gets a $1500 discount from the previous model year, so it now only costs $995 more than the 5.3-liter V-8.

We like the Sierra Elevation trim level because it occupies a middle ground in terms of price but comes with a desirable appearance package that looks cool. You'll also have to select between a few different cab configurations and bed lengths depending on what fits your needs. All-wheel drive is available at an extra cost should you require it.
