The 2020 GMC Sierra HD debuted earlier this month with improved looks, a bigger footprint and new technologies, ushering in a new era for General Motors’ premium truck and SUV brand.
While the new Sierra HD certainly looks different than the outgoing model, it’s not quite as radical of a redesign as the 2020 Silverado HD. Judging by the internet’s collective response to that truck, that’s probably a good thing. That’s not to say GMC hasn’t changed quite a lot, though. The new Sierra HD is much bigger than before and has more cargo and passenger space. It also has a wider set look than the outgoing truck, giving it a more confident stance.
Under the hood is an available Duramax 6.6L turbo-diesel L5P engine that offers an SAE-certified 445 horsepower and 910 pound-feet of torque. The only available transmission is a 10-speed automatic, which is Allison branded but isn’t actually designed or built by Allison. A new gas engine will also be available, but GM has yet to provide details on that engine.
Other features on the 2020 GMC Sierra HD include GMC’s ProGrade Trailering System, which includes a rear-vision camera with hitch-view, an auto-electric parking brake, an integrated trailer brake controller, hitch area lighting and an in-vehicle Trailering App with trailer diagnostics. GMC will also be offering an off-road focused AT4 variant, which gets Rancho shocks, underbody skid plates, an off-road driving mode, a locking rear diff and 18-inch wheels shod in all-terrain tires. Don’t forget the available MultiPro tailgate, either.
The interior isn’t so different from the outgoing GMC Sierra HD, unfortunately, but GM has thrown in a new rear camera mirror and an available 15-inch-diagonal head-up display. There’s new leather trim colors and new available wood trim, too.
