With a generous selection of powertrains, drivers get the performance they need out of the 2019 GMC Sierra 1500. Options include the standard 310-horsepower, 2.7-liter Turbo engine, a new 355-horsepower, 5.3-liter V8, a new 3.0-liter Duramax Turbo Diesel engine, and a new available 6.2-liter V8 with Dynamic Fuel Management. The latter two come with a smooth, all-new ten-speed automatic transmission. These strong engines work with advanced systems to provide a confident, strong towing performance. The truck operates on a new traction select system, an available Integrated Trailer Brake Controller, and an available Max Trailering Package, which empowers the 2019 Sierra 1500 to tow up to 12,200 pounds.
