2021 Sierra 1500 Exterior
If you want to buy a 2021 GMC Sierra 1500, best to keep away from crows and magpies. The one thing you do get as standard across the range is chrome. It is available in three different cab configurations and two load bed options, but even the most basic regular cab workhorse has a massive piece of chrome surrounding the grille. The higher up you go, the more chrome GMC adds. LED exterior lights are standard across the range, and wheel sizes range from 17-inch on the workhorses to optional 22-inch alloys on Denali and Elevation models.

Dimensions
The only static measurement across the entire range is the width of 81.2 inches, with the rest of the dimensions changing based on a number of factors. Overall length is 229.6 inches on the Regular Cab with an eight-foot bed, 231.7 inches for Double Cabs with a 6.6-foot bed and Crew Cabs with a 5.8-foot box, and 241.3 inches for a Crew Cab with a 6.6-foot bed. The Regular Cab has a 139.5-inch wheelbase, while the Double Cab rides on a 147.4-inch wheelbase. The same figures count for the Crew Cab in standard and AT4 format, but with a 6.6-foot bed, the wheelbase increases to 157 inches. The AT4 trim adds another 0.1 inches to the wheelbase. Heights vary substantially, too, ranging from 75.4 inches on a Crew Cab 2WD with the medium-sized box to 78.5 for the Double Cab AT4.
The Sierra is a substantial piece of machinery, with a curb weight to match. The base Regular Cab has a curb weight of 4,430 lbs, while on the other end of the spectrum, the heaviest is the 5,340-lb Crew Cab AT4, only available with the 4x4 drivetrain. Speaking of the latter, it comes with the most impressive set of off-road-related figures. The approach, breakover, and departure angles are 28.7, 20.4, and 27.2 degrees, respectively.
