THE 2020 SIERRA HEAVY DUTY OFFERS MORE POWER, CAPABILITY, AND TRAILER TECHNOLOGY THAN EVER BEFORE
GMC stepped up its game with the 2020 Sierra Heavy Duty! This truck was built stronger, produces more power, and features greater trailering capabilities with the latest technologies.
“The all-new 2020 Sierra Heavy Duty is the most capable heavy-duty truck that we’ve ever offered,” said Duncan Aldred, vice president of Global GMC. “For customers who demand a premium, innovative heavy-duty truck that supports their passions, the next-generation Sierra HD can pull like a pro.”
Built to power through anything, the 2020 Sierra Heavy Duty features a choice of an all-new 6.6L V-8 gas engine rated at an SAE-certified 401 horsepower and 464 lb.-ft. of torque or an all-new segment-first Allison 10-speed automatic transmission paired with the mighty Duramax 6.6L V-8 turbo-diesel engine, producing an SAE-certified 445 horsepower and 910 lb.-ft. of torque.
Built with a larger frame and stronger propulsion system, the all-new Sierra Heavy Duty offers a maximum trailering rating of 35,000 pounds and a GCWR of 43,500 pounds.
“Trailering is the most important consideration for Sierra Heavy Duty customers, and the new features and technologies in the 2020 Sierra HD make it easier than ever to hitch a trailer and tow it confidently,” said Jaclyn McQuaid, vehicle chief engineer, Heavy Duty Trucks. “We’ve developed this new truck to offer the greatest trailering experience ever offered by GMC.”
Not only does the all-new heavy duty truck feature an available class-leading 15-unique camera views, including an industry-first transparent trailer view, but it also boasts a ProGrade Trailering System with an in-vehicle Trailering App, as well as other available trailer technology designed to permit access inside the trailer from your phone. The ProGrade Trailering System features a trailer light test, Trailer Electrical Diagnostics, Trailer Tire Pressure and Temperature Monitoring, Pre-Maintenance REminders, and Departure Checklist. The Sierra Heavy Duty also features smart trailer technology that is designed to allow access to select features of the iN Command Control System from ASA Electronics through the MyGMC Mobile App. Through the app, drivers can turn on the air conditioning, or the water heater, check water and holding tank levels, or monitor fuel levels on trailers equipped with gas generators.
The all-new Sierra Heavy Duty also offers an off-road package with the Sierra Heavy Duty AT4 that features a unique suspension and supporting technologies such as off-road suspension, Rancho Shocks, skid plates, and an Eaton Locking Rear Differential. The off-roading package also includes Hill Descent Control and Hill Start Assist as well as Traction Select System with specific Off-Road mode.
