Two versions of the all-new 2020 GMC Sierra Heavy Duty, which the manufacturer bills as “bigger, stronger, and smarter,” will be arriving in dealerships late this summer. Pricing and complete specifications will be detailed at a later date.
The 2020 Sierra HD, which will be available in 2500HD and 3500HD dual-rear-wheel and single-rear-wheel configurations, was the beneficiary of a $1.5 billion investment in General Motors Co.’s Flint Assembly plant.
“The all-new 2020 Sierra HD is the most capable heavy-duty truck that we’ve ever offered,” says 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.”
Features, which focus heavily on the new vehicle’s towing capability, include:
- An enhanced ProGrade Trailering system featuring available 15 camera views, including a segment-first transparent trailer view to virtually see through a trailer in tow.
- An available smart trailer designed to integrate the iN∙Command control system from ASA Electronics provides the ability to monitor and control select functions of compatibly equipped trailers through the myGMC mobile app.
- A segment-exclusive available 15-inch-diagonal head-up display that offers useful trailering information, including vehicle speed, navigation information and an inclinometer display for the road grade.
- An available segment-first rear camera mirror.
- MultiPro, the world’s first six-function tailgate, allows easier loading, unloading and bed access and is available on all trim levels.
- A design that provides more room for cargo and occupants.
- Best-in-class crew cab front headroom and legroom for the driver and other front-row occupants.
- An all-new, segment-first, Allison 10-speed automatic transmission mated to the legendary 6.6L Duramax turbo diesel.
“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,” says Jaclyn McQuaid, vehicle chief engineer of Heavy Duty Trucks. “We’ve developed this new truck to offer the greatest trailering experience ever offered by GMC.”
For drivers looking to take refined capability off-road, GMC fortifies the new AT4 brand with an all-new Sierra AT4 Heavy Duty available for crew cab configurations as both a 2500 and 3500 single-rear-wheel offering.
