The 2021 Chevrolet Silverado 3500 marks the second model year of its fourth generation. This heavy-duty workhorse is available in 2WD or 4WD, with either a Double or Crew Cab. Engine options include a 401-hp 6.6-liter V8 or a potent 445-hp 6.6-liter Duramax Turbo-Diesel V8 mated to a 10- or 6-speed automatic transmission, respectively. Trim levels range from WT (Work Truck) to High Country, with ample options for customization. Key features span beyond prowess and payload, like the 15 available camera views to aid in towing and maneuvering, and the Chevrolet Infotainment System with an 8" diagonal color touchscreen that supports both Apple CarPlay and Android Auto. Advanced driver aids, such as Forward Collision Alert and Automatic Emergency Braking, are key for safety. Notable for 2021, the Silverado 3500 Heavy Duty received significant updates to its towing capability.
