Performance

The Sierra 3500HD offers two V-8 engines, gas or diesel, depending on your preference. The gas engine is a 6.6-liter V-8 featuring RWD as standard and 4WD as an option. It produces 401 horsepower and 464 pound-feet of torque, an upgrade well over the engine it substitutes. Still, the six-speed auto transmission renders it outmoded compared to competitors with higher transmission speeds.

Tech

Each Sierra model comes standard with Android Auto and Apple CarPlay Auto, a 7.0-inch touchscreen on base models, and an 8.0-inch monitor on upper trims. The SLT, AT4, and Denali trim levels come with internet radio and voice commands; Denali models will include integrated navigation. Also, entry-level trucks have a 3.5-inch display, whereas higher trims feature 4.2- or 8.0-inch displays.

Cargo Space and Interior Room

The Sierra 3500HD has various cab and bed configurations. Regular cab variants with two or three seats are only available with an 8-foot bed and 83.5 cubic feet of cargo space. Double cab models accommodate five or six people and offer 35.2 inches of boot space. These trucks may be paired with either a regular 6-foot-9-inch bed with a cargo space of 69.6 cubic feet or an 8-foot-long bed. The spacious crew cab model increases back legroom to 43.4 inches while keeping the double cab’s standard and extended bed choices.

Safety

Rating

2023 GMC Sierra 3500 HD Review

This enormous pickup drives like a big truck and provides the safety and comfort required while driving. The double cab has enough internal space for a work team, while the extended cab has extra leg room so everyone can be comfortable. A higher trim level translates to better truck features.
