2020 GMC Sierra 3500 Overview

The 2020 GMC Sierra 3500 belongs to the model's third generation. This heavyweight pickup truck offered two engines: a 6.6-liter V8 that generates 401 horsepower mated to a six-speed automatic, and a turbo-diesel 6.6-liter V8 providing 445 horsepower hooked up to a ten-speed automatic transmission. The model is available in dual rear wheel (DRW) and four-wheel drive configurations. Four trims levels are provided: base, SLE, SLT, and Denali. The Denali trim offers luxurious features equivalent to many high-end cars and SUVs. Key safety features include available forward-collision warning and automated emergency braking. The Sierra 3500 also features an Infotainment system with a 7-inch or 8-inch touchscreen available, and Apple CarPlay and Android Auto compatibility. Notably, for 2020, GMC completely redesigned the Sierra 3500, significantly enhancing both its capabilities and feature availability.
