2021 Sierra 3500HD Photos
The Sierra 3500 HD delivers a bold looking exterior with very capable payload and towing values. The GMC Sierra is offered in both 4x2 and 4x4 models with either a single rear wheel (SRW) or a dual rear wheel (DRW) configuration as well as a wide array of trims and class exclusive features and options. The Sierra HD comes in one of several different body styles with long and short bed options. However, despite this complexity there are only two available engines, both V8 units displacing 6.6 liters. The gasoline option is paired to a 6-speed automatic and makes 401 horsepower and 464 lb-ft of torque. The more expensive diesel engine is aided by a turbocharger and makes 445 horsepower and a massive 910 lb-ft of torque. Unlike the gasoline engine, the diesel is mated to a 10-speed automatic to handle all that torque. When properly equipped, a Sierra HD 3500 should be able to tow up to 35,000lbs with a 5th wheel attachment, or 20,000 lbs with a traditional trailer hitch, thanks in large part to the massive torque produced by its diesel V8. Sierra buyers are also offered plenty of choices when it comes to the tech in their new vehicle. GMC?s ProGrade Trailering system features fifteen camera views to help keep an eye on things behind the truck, even counting a class exclusive transparent trailer view among its features. The available heads up display on the Sierra HD is massive, measuring 15-inches across, while the rear-view mirror can be switched between displaying an actual mirror and the view from the rearward facing camera. GM claims their MultiPro tailgate is the world?s first six-function tailgate. In practice that means it?s easy to load things into and out of the back of the truck, while also providing a ton of utility options for carrying loads with the tailgate dropped. It also has a built-in step to make it easier to climb in and out of the bed of the truck. For 2021, the Sierra HD lineup is introduced with more wheel options, more exterior color choices and some new technology as standard on various trims.
