All-New GMC 2020 Sierra Heavy Duty – Duramax 6.6L engine
Bigger, stronger and smarter, the all-new 2020 GMC Sierra Heavy Duty combines greater trailering capability with technologies designed to provide customers with a world-class towing experience.
ProGrade Trailering Technology
First introduced with the 2019 Sierra light duty, the ProGrade Trailering System leverages technology advancements to offer additional features and functionality for the 2020 Sierra Heavy Duty.
“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.”
Bigger and bolder
The 2020 Sierra HD has a commanding, powerful design rooted in a new architecture with larger proportions. It is taller and longer, with a more confident stance defined by a bold design that epitomizes GMC’s signature refinement and technologically driven attention to detail.
The all-new Sierra HD is highlighted by new signature lighting, including prominent “light blades” that deliver LED illumination for the daytime running lamps. LEDs are also used for the headlamps, taillamps, available fog lamps and other illuminative elements, including the available roof marker lights standard on all dual-rear-wheel HDs and all Sierra HD Denalis except where prohibited by law.
Inside, the Sierra HD’s new interior has best-in-class front head- and legroom (maximum), with Crew Cab models. A higher seating position complements the truck’s taller profile to offer a confident view from behind the wheel. Additional optimized ergonomics emphasize easy, intuitive interaction with the vehicle’s available technologies, such as a heavy-duty segment-first head-up display and GMC’s latest touchscreen infotainment systems.
