2021 GMC Sierra 3500HD Overview

The 2021 GMC Sierra 3500HD is a robust, full-size pickup meant for heavy-duty operations. It's part of the fourth-generation Sierra debuting in 2019. The truck is available with two engines: a 401-hp 6.6L V8 or a turbo-diesel 6.6L V8 producing 445-hp and astounding 910 lb-ft of torque. Both engines mate to a six-speed automatic transmission, with four-wheel drive as standard for the diesel and optional for the base engine. Four trim levels are available: Base, SLE, SLT, and luxurious Denali. Tech-wise, a 7-inch touchscreen comes standard, but an 8-inch version with Apple CarPlay and Android Auto comes in upper trims. Key safety features include a rear camera, available forward-collision warning, blind-spot monitoring, and lane-departure warning. The 2021 model introduces a bed-view camera and trailer-length indicator for safer towing.
