2021 GMC Sierra 1500 vs 2021 Chevrolet Silverado 1500


The truck competition has been fiercer than ever before. As many truck owners debate which options are better than others, the 2021 GMC Sierra 1500 offers one of the more well-rounded experiences in the class.

However, the 2021 GMC Sierra 1500 shares many similarities between it and the 2021 Chevrolet Silverado 1500. While both brands are owned by General Motors, there are distinct differences between the two. At Palmen GM, we provide a comparison of two similar, yet quite distinct models. To provide some context, Palmen GM provides a comparison below:

While both models share many features, several options are slightly different. One major difference between Work Truck trim levels comes in the slightly longer 2021 GMC Sierra. Meanwhile, the front seats offer just a hint of extra space - likely only due to minor upholstery or feature adjustments between both models. Otherwise, the 2021 GMC Sierra 1500 is most known for its focus on its upper six trim levels compared to Chevrolet’s focus on mid-tier trims. Such options in the GMC Sierra include the Denali trim level, which offers the world’s first Six-Function MultiPro Tailgate and a segment-exclusive Continuous Damping Adaptive Ride Control.
