The 2021 Chevrolet Silverado 2500HD is part of the fourth-generation Silverado lineup. As a heavy-duty pickup truck, it delivers unparalleled towing and payload capacities, making it a mainstay in its class. Available trims are WT, Custom, LT, LTZ, and luxurious High Country. Depending upon the trim selection, a 6.6-liter V8 gasoline engine that produces 401 hp or the 6.6-liter Duramax Turbo-Diesel V8 that boasts 445 hp are at disposal. While the former pairs with a 6-speed automatic transmission, the latter teams up with a ten-speed automatic. Both RWD and 4WD drivetrains are available. Advanced safety features like forward collision alerts, lane departure warning, and safety alert seat are optional. The infotainment system is managed via a 7" or 8" touchscreen, with optional navigation, and supports Apple CarPlay and Android Auto. A significant upgrade from the 2020 model includes the new Multi-Flex Tailgate on all but base model trims.
