We hope it happens.
As the new Chevrolet Suburban is based on GM's new T1 architecture, it is expected to be capable of towing huge payloads and will boast new technologies to aid it in doing this. The platform is capable of handling huge weight ratings, which is why fans of the Suburban have been speculating about the possibility of a new heavy-duty variant. It seems that it's not just Chevrolet's fanbase that realizes the truck's potential as GM's vice president of Global Product Programs, Tim Herrick, has hinted at an HD Suburban himself. This would be the first time since the end of 2018 that the Suburban would be so capable.
Herrick clearly loves trucks, and his comments on heavy-duty stuff are encouraging: "I have full-size truck stuff in my blood, right? So I understand what it takes to make a light-duty truck, a heavy-duty truck, an SUV, make them all together architecturally work, and then expand that architecture, whether it's putting batteries in, or different engines and the like. Expanding the architecture architecturally would be great. And with that, then you bring, maybe a heavy-duty Suburban."
This would open up possibilities for aftermarket companies and Chevrolet itself to offer bulletproof Suburbans that can handle the added weight of armor. With its attractive looks, we're sure that the rich and famous would be happy to roll in an upgraded Suburban.
As it is, the Suburban range is already quite attractive - especially when you look at the rugged Z71 model, but a supremely capable Suburban or Tahoe would draw in more customers who have had to look elsewhere since 2019. With improved capability, we expect that the potential Suburban HD would get a more powerful engine too. At present, the most powerful model in the range is the High Country with a 6.2-liter V8 developing 420 horsepower. Big V8s are part of the Suburban HD's history, so perhaps an upgraded version of this same engine would power the new model - if it does indeed happen. If a bigwig at GM is talking about it, holding our breath for it doesn't seem fruitless.
