The 2020 Chevrolet Silverado 3500HD represents the third generation of Chevy's heavyweight class of pickup trucks. Under the hood, buyers have the choice between a 6.6L V8 gas engine producing 401 hp and a Duramax 6.6L Turbo-Diesel V8 that cranks out 445 hp. It's available in 5 trims: Work Truck, Custom, LT, LTZ, and High Country. They come with either RWD or 4WD, and transmissions include a 6-speed automatic for the gas model and a 10-speed automatic for the diesel. Key safety features include forward collision alert, lane departure warning, and automatic emergency braking. Inside, infotainment is handled by a 7-inch or available 8-inch touchscreen featuring Apple CarPlay and Android Auto. One of the major highlights for the 2020 model year is the significant increase in towing and payload capacity, with the truck capable of hauling up to 35,500 pounds when properly equipped.
