GM Reveals their New 2020 GMC Sierra HD
With Chevrolet set to debut their new 2020 Silverado HD trucks in February, it was a safe bet that GMC would release their new 2020 Sierra HD around a similar time. While both the Silverado HD and Sierra HD share the legendary Duramax-Allison combination, these trucks have vastly different exterior appearances, different interiors, and different features. GMC just revealed their 2020 GMC Sierra HD and gave us a taste of what the new heavy duty GMC trucks have to offer. Here is what we’ll be missing out on until Late Summer this year, when they become available.
The New 2020 GMC Sierra Heavy Duty Exterior
The new 2020 GMC Sierra HD received an exterior overhaul. The new Sierra HD is both taller and longer. The front of the truck features an elevated hood line and a new grille that helps aid in air induction. Door mounted tow mirrors provide drivers with power extending and retracting mirrors. All new segment-exclusive bed-side steps provide easier access to the bed and cargo. These bed-side steps compliment GMC’s existing Corner steps that are found in the rear bumper. The 2020 Sierra HD trucks also received the first ever six-function Multipro tailgate. Stay posted, we’ll be going over the new tailgate in another post.
New lighting including headlights, running lights, taillights, fog lights, and cab lights also adorn the truck, using LED technology for better illumination. The towing mirrors also come with available led lighting.
The 2020 GMC Sierra HD also contains a new interior that proudly takes the trophy for best-in-class front head-room and leg-room for crew cab trucks. GMC owners will have a superior perspective of the road because of a new, higher seating position. A segment-first heavy-duty head-up display helps drivers pay greater attention to both the road and their truck. As if that wasn’t enough, Premium leather seating, authentic open-pore wood trim, and dark aluminum decor add to the luxury and interior appeal of GMC’s new 2020 Sierra HD.
New Technology on 2020 GMC Sierra HD Trucks
The 2020 GMC Sierra HD not only has a totally redesigned exterior and interior, but also a myriad of new features designed to provide customers with a premium truck that make life easier. Drivers who frequently tow will be thrilled with the addition of numerous technological additions geared towards towing. These new additions include a new ProGrade trailering system with up to 15 available trailer views, rear camera mirror, and an all-new smart trailer system to be used with compatible “Smart” trailers. We will go more in depth on the Sierra HD’s new technology in a following article.
A New Trim For The 2020 Sierra HD Lineup
The new heavy duty Sierra will also be available in a new trim, the AT4. The AT4 will provide GMC customers with superior off-road capabilities. AT4 trucks receive an off-road suspension, Rancho Shocks, skid plates, and an Eaton locking rear differential. 18″ or 20″ wheels mated with Michelin AT tires provide traction in a variety of terrains. AT4 trucks also come standard with a traction select system, hill descent control and hill start assist. Sierra HD AT4 trucks will also have some differences with their exterior and interior. We go over that in greater detail here.
2020 GMC Sierra Heavy Duty Performance
Because this Duramax still produces 445 horsepower and 910 lb/ft of torque, we believe the 2020 GMC Sierra HD’s L5P engine has not received any major changes. However, GM is pairing the L5P Duramax with a new 10-speed Allison transmission for 2020 trucks. According to GMC, this will help keep the engine in an optimal range in all terrains and load conditions. GMC believes because of a new, stronger frame, trailer tech, and greater performance, the new Sierra HD will be capable of a tow capacity greater than 30,000 lbs.
Don’t forget to keep up with us as we cover every aspect of these new Sierra HD trucks. They won’t be for sale until close to the 3rd quarter of this year. That means you have quite a few months to convince your wife that you need a new truck!
