Here’s an interesting fact: the Denali trim is the most popular model of the GMC Sierra HD.
Over 50 percent of GMC Sierra HD buyers choose the range-topping Denali trim, and more than 90 percent of those trucks are equipped with the Duramax turbo-diesel V-8 engine, GMC’s Fred Ligouri told GM Authority.
Earlier this month, GMC unveiled the all-new, 2020 Sierra HD. The range-topping 2020 Sierra Denali HD model stole the debut spotlight in an impressive clip. New from the ground up, the 2020 Sierra HD delivers advancements in every category, including comfort, capability, ease of use, and technology.
The 2020 GMC Sierra HD will be offered in five trims: base, SLE, SLT, the new AT4, and Denali. The lineup will include 2500HD and 3500HD capability variants, Regular, Double Cab and Crew Cab cab styles, as well as Standard and Long cargo boxes. In addition, two chassis cab frame lengths will be offered.
Under the hood is a choice of two engines: a 6.6L V8 L8T gasoline engine with 401 horsepower and 464 pound-feet of torque and the familiar 6.6L V8 L5P turbo-diesel Duramax, which is rated at 445 horses and 910 pound-feet of torque. The gasoline V8 will be paired with GM’s 6L90 six-speed automatic transmission, while Duramax-powered models will receive an Allison-branded 10-speed automatic.
Notable advancements of the all-new models include:
- Enhanced ProGrade Trailering system with an available 15 camera views
- Available smart trailer system that integrates the iN-Command control system from ASA Electronics and grants the ability to monitor and control select functions of compatibly equipped trailers through the myGMC app
- Available 15-inch-diagonal head-up display
- Available Rear Camera Mirror
- Available MultiPro tailgate
- Towing capacity up to 35,500 pounds
Pricing for GMC’s entire 2020 Sierra HD lineup will be announced closer to the launch date this summer. Stay tuned to GM Authority for more GMC news and Sierra news coverage.

This does not surprise me at all even though I’m in the minority of weirdos that only wants a gas HD so I’m thankful for the new 6.6 gas. I thought GM forgot about us until now. As much as I’ve liked my 6.0’s it’s time to move on.
The gas HD is alright unless you’re going to tow something really heavy a lot of times like a big RV.
No argument there. I idle a lot in hot and cold weather along with plenty of starting and stopping with short trips during it’s life and a modern diesel is just not an option for me anymore. I’d take a diesel over gas any day if it wasn’t for the emissions and DPF junk attached to them.
Fortunately, My Chevy Duramax is an 02 and doesn’t have any of that crap on it. Doesn’t require any
fluids to be added to the fuel at any time.
What pisses me off and I dont know why GM DOES NOT FIX THIS… ALOT OF US HATE THAT WE ARE FORCED TO BUY ALL THAT HIDEOUS CHROME IF WE WANT A DENALI. I’ve talked to alot of GMC Denali owners and they agree, we should be able to get all that chrome finished with body color paint.. PLEASE GM GIVE US GUYS WHO HATE CHROME A DENALI DONE OUR WAY TOO!!!
Relax, it’s actually just plastic made to look like chrome. They spared no expense.
The reality is they want to make the Denali special enough to get people to pay more for it.
GMC has created the exact deal Cadillac wants, needs and has failed to create. They used to have it but they now are a car that most people can have and it killed their image.
The key is the Denali is not a truck that just everyone should have. It makes for a top image and makes more money.
FYI just bolt a grill on if you want the chrome and nothing else. Many do.
What about the AT4? That has the colored bumpers and black chrome grill/moldings. This is what I like 🙂
Are there gonna be any kind of rebate on the new 2019 model 3500HD Denalis?
1) 6 speed? Wtf. Ford’s offering a bigger gas engine and a 10 speed. This seems like typical half hearted cynical crap from gm handicapping the new gas offering to ensure people keep ponying up the $10k extra for a duramax.
2) Will Denali be available in a 2500 cclb configuration? Past years I have had to settle for slt because gm does not see fit to offer Denali in that size except with a dualie.
Why do you care how many speeds the transmission has?
I tow a 16,000 lb 5th wheel with a 4 speed Alisson and have no problems.
Oh! I forgot I’ve got a Duramax. Don’t really need 10 speeds.
More speeds = better fuel economy and driveability. In an hd truck where conditions can range from totally unloaded to towing 35000lb, more speeds allow better tailoring operational rpm to the task at hand.
Afaik Duramax +Allison has always had at least 5 speeds.
Again, If you buy the diesel you don’t have to worry about it when towing. And by the way, if you’re not familiar with diesel. They get the same gas mileage whether you’re doing 55 or 85. I drove 214 miles in my Duramax 2500 HD at 85 mph and got 20.6 miles to the gallon, and the truck ways 7500 lbs.
Stating that fuel economy of a diesel doesn’t change with speed traveled is simply ridiculous and incorrect.
The Allison 1000 Series transmission has never been a 4 speed, only a 5 or 6 speed. If you have a diesel GM truck with a 4 speed transmission, you do not have an Allison, nor do you have a Duramax.
Exactly. But as you can see, I was thumbed down relentlessly for trying to make the same factual correction. Apparently the crowd here is WAY smarter than us dunderheads who actually own and use actual hd diesel trucks.
I think I’ll wait for the inevitable interior redesign. Looked at a 1/2T and couldn’t stomach it. Largely the same as current generation interior which is already the weakness of the 2018 models. And that tiny touchscreen is just ridiculous. They have a huge wide plastic switch bezel over the entire center stack and then it tapers to this tiny narrow screen just making it scream “look at me! I’m a tiny pinhead!” Hopefully this is a 1 year problem as it looks like they protected space for a more appropriately scaled display and just held it back from us. The whole thing just looks like the Aztec and h2 interior team got back together to have 1 more go at it. God save gm if they need to be copying ram in order to figure out what a nice design looks like.
I really wish they would go back to using the Tahoe / Yukon dash in the higher trim trucks. This cost nothing in terms of design expense and was a good differentiator to elevate the SLT and Denali above the plebian work trucks. I’ve driven those SUVs and enjoy that interior much more so that the crappy truck design
Don’t fret too much on the screen size. My brother’s new RAM 12” screen is so big that you can get lost trying to locate what you want. At lot can be displayed but while driving you can take your eyes off the road too long while scanning the screen. Some icons are on the bottom portion of the screen that really lowers your eyes downward from the road. It’s a nice screen, easy to use but a bit too much for a vehicle.
I bet you didn’t think about the fact that in two years time that paint will have a thousand rock chips in it and look like shit!
I prefer chrome. Easy to keep clean. I understand the paint idea though it looks nice for the first six months.
Who would of thought? An $80,000 pickup could get lost in a parking lot?
I would buy one too, if I had the money.
Kind of related: Have to say: That sure is a FINE looking Silverado pacing the Daytona 500 today. Color, trim, everything just perfect. Chevrolet should assign an RPO to it and offer it for sale…. At least the exterior anyway..
Your story is a little off, GM has had major constraints on gas engines for HD trucks all year. If you look at GM HD truck inventory you will notice that 95% are diesel (exclude work trucks)
Do we know what colors the AT4 comes, and configurations? I’m interested in a double cab AT4 but like dark gray.
Does anyone know if you can custom order a paint that is not on the GM color list for 2020.
I want Satin Steel Metallic but hey don’t have that color listed anymore. They did have it available on the 2019 GMC color list.
The colors they list for 2020 are, White Frost Tricoat, Cardinal Red, Pacific Blue Metallic, Quick Silver Metallic, Summit White, Onyx Black, Carbon Black Metallic, Dark Sky Metallic, Brownstone Metallic and Red Quartz Tincoat.
If anyone knows how to get an old color please let me know. Thanks.
