Refreshed 2024 GMC Sierra HD Interior Spied For The Very First Time

For the past year, GM Authority has been reporting about the upcoming refresh to GM’s full-size heavy duty pickup pickup trucks. And now, our spies have captured the very first photos of the 2024 GMC Sierra HD interior, which show the center stack – along with several other components – almost entirely undisguised.
First, a few words about what we’re looking at: this is a refreshed Sierra HD in the Crew Cab, Long Box configuration and the Dual Rear Wheel (dually) setup. The trim level is a bit of a guessing game at this point, but we are certain that it’s either the SLE or SLT, and not the base Pro (judging by the presence of various chrome bits on the body) or the range-topping Denali (going by the lack of the standard running boards and trim-specific wheels). Back to the interior. Under the hood is the 6.6L V8 L8T gasoline engine rated at 401 horsepower and 464 pound-feet of torque in the current Sierra HD.
The new center stack configuration looks similar, if not the same, to the one seen on the refreshed 2022 GMC Sierra 1500, with the infotainment system being an exact match for the 13.4-inch unit in the Sierra HD’s half-ton relative. Meanwhile, the button arrangement and HVAC controls below the dash seem to be in line with the SLE or SLT trims in the 2022 Sierra 1500.
It’s worth pointing out that this particular 2024 GMC Sierra HD prototype has the column shifter, a feature that was replaced by a console shifter on the refreshed 2022 Sierra 1500 with the front bucket seat configuration (models with the front bench seat retained the column shifter, for obvious reasons). It’s possible that this particular 2024 GMC Sierra HD prototype is also equipped with the front bench seat option, and that models with the front bucket seat setup will get the console shifter instead.
The 2024 GMC Sierra HD refresh is expected to bring a slew of updates and changes to Big Red’s big rigs in the form of restyled front and rear ends, an overhauled cockpit, updates to the powertrain, and a new Sierra HD AT4X model, as first reported by GM Authority last week.
As for the powertrain updates, we expect the refreshed Sierra HD to replace the GM 6-speed automatic transmission with its newer 10-speed counterpart for models equipped with the L8T gasoline engine, while the 6.6L V8 L5D turbo-diesel Duramax engine is expected to get a boost in power and torque to over 500 horses and 1,100 pound-feet of torque.

Course the interior isn’t what they need to hide. It’s planned on being 95% the same as the refreshed half ton. The real surprise is what lies under the hood. Will the new Dmax include a turbo compounder like the Detroit diesel as its means of reaching its power? Will they go the hack Cummins route and just run a bigger turbo and lower compression? Or have they developed something new entirely?
I’m also interested in knowing if they beef up the 10 speed transmission.
Good question. There’s a chance the 10 speed “Allison” was designed for future torque updates and already has it in there. The 10l90 transmission that’s paired with the 6.2 standard truck is very similar to the one behind the LT4 and can take 650ftlbs of torque so that with the 6.6 gasser won’t flinch
Good. They need to keep the column shifter in the HD trucks. Shame they removed it in the 1500s.
They didn’t remove it completely from the 1500’s. The column shifter can be configured with bench seating in the front. Very limited to trim levels though, I agree. I do like the new console shifter though for me personally. To each their own.
Any particular reason you like the column shifter better? I’ve heard that sentiment from numerous different individuals and I’m wondering what I’m missing as I find the console shifter to be much more user friendly and aesthetically pleasing.
Plowing. Also it makes it feel like some lame SUV or car and not the trucks we’ve been driving our whole lives.
Did you miss the plowing part?
No.
You do a lot of plowing do you?
You can’t even plow your own driveway.
I do several bench seat swaps each year for my customers who want a fully loaded truck with 6 seats. I can’t do that with the 1500s anymore. Personally I drive a 2013 Tundra with console shifter, and I find it in the way far more than convenient. I would prefer a center console with more compartments/organization rather than the shifter there. I do not understand the appeal, but I recognize that it exists.
I can’t wait to see all of it! Hopefully it looks decent, I’m starting to get worried that vehicles will start looking “too” futuristic for my likeings…
Keep the column shift in the HD. And bring us this update for 23, not 24 please…
Fix those god forsaken mirrors. They are atrocious!
They work really well pulling a gooseneck. Can’t live without them now. Seems like I can’t see anything getting into my 21 1/2ton afterwards.
They are useful, to heck with looks. Where they’re mounted helps reduce the blindspot. They aren’t designing this truck for you anyways, it is a tool. Stay in your luxury CUV lane…
I would like to see that 6.6 liter Duramax Diesel make its way in a new 3/4 ton HD Suburban💪🏾💪🏾💪🏾💪🏾
I am looking forward to the MCR for the HD’s, but I was also hoping it would land for 23 also, but I will wait until 24 if I must. And please GM, for 23, 24 and whenever, make the Chevy 3500 dually factory available with the “Midnight Edition” or the all black “Sport Appearance Package” like you had in 2019. My 19 is handsome in all black with polished wheels. It matches my 87 Buick GN nicely.
Funny enough, not really concerned about the power, as the current L5P tows like nothing is behind you anyway.
Every couple years, they’re going to update it,it’s the same damn thing with a little bit more junk plastic on the inside so they can charge $5,000 more for it and those mirrors suck I got a 3/4 ton that I’ve had for a year got 60,000 miles on it is absolutely the worst mirror configuration I’ve ever had on a truck
TO ALL THE PEOPLE THAT PULL TRAILERS , THE NAV SCREEN IS 13 INCHS WIDE BUT ONLY ABOUT 6 INCHS TALL , AND THE SCREEN SITS TO DAM LOW ON THE DASH , WHEN BACKING YOU HAVE TO KEEP LOOKING DOWN, AND ITS EVEN LOWER THAN THE GAUGE CLUSTER , THINK ABOUT IT , FORD AND RAM IS 3 INCHES ABOVE THE DASH, THE BEAN COUNTERS ARE JUST MAKING ALL THE DASH’S THE SAME IN ALL TRUCKS AND SUVS. THE DASH IS LAME AND WEAK LOOKING. AND YES THE MIRRORS LOOK DAM STUPID, GM IS WEAK. EVERY ONE KEEPS TALKING ABOUT THE 505 HP DURAMAX , IT WILL BE A JOKE, AND YOU WON’T GET 505 HP AT THE GROUND. I HAVE A 2022 SPORT CHASSIS WITH THE DETROIT 12.8 L DD13 , 505 HP AND 1850 TORQUE, SO HOW DO YOU GET 505 HP IN A GM SISSY MOBILE WITH THE GIRLY DASH. RAM WENT FROM 900 LBS OF TORQUE ON THE 2016 RAM 3500 AISIN TO THE 2021 RAM HAS 1075 LBS OF TORQUE, AND YOU CANT TELL THE DIFFERENCE FOR NOTHING BECAUSE BOTH PULL VERY WELL THE SAME. GM IS BEING RUINED FROM THE CORE, ITS SO BAD.
COOL IT BOOMER.
IF YOUR EYESIGHT IS REALLY THAT SENSITIVE THEN YOU SHOULDN’T EVEN BE DRIVING, LET ALONE PULLING A TRAILER! JUST DON’T BE MAD WHEN THE NEW DURAMAX GAPS YOU WHILE PULLING A HEAVIER TRAILER!
You really wanna control what people can do.
This makes my eyes rain, why are you so xtra bruh? Where did the DMax touch you or was it uncle GM?
Yep, still ugly as sin, both inside and out. Especially the disgusting tow mirrors. Beavis anyone?
The GM interiors are a joke. The Denalis are the same quality as a Ford Lariat but for $20K more.
Went from the best looking HD trucks in ’19 to the ugliest in ’20 and no sign of backing down. The sales numbers show it too.
They are always playing catch up now.
Must be cool to have the ability to see through camo! I would give your interior comment credit pre-refresh, but your smoking some good stuff if you think the Lariat has a nicer interior than the refreshed Denali line.
What are you smoking? Considering the fact you want to dictate what people say you must be smoking something good. If you hate America just say that.
I sure wish some of these changes pop up in 23 vs. 24.
GM dangles carrots for all you die hard GM fans, and there still running last decades duramax , and opted for a fake allison transmission, they change a paint color , or add black wheels, and everyone go’s crazy. Bean counters , thin seats, cheap unfinished plastic all over the exterior, blown plastic interiors, o yea and the new car dash revamp and stupid looking door mounted mirrors, good for a year tires , no wow factor, the most talked about motor lately is a 4 banger,
You have issues. Find a cathartic hobby.
I want my MTV….Just Kidding Dire Straights… I want My Re-Fresh Cabin HD in 2023. The You Tube videos of the 2022 1500 Re-Fresh dash, look awesome to me. But try to find one on a dealer’s lot.
Disturbing, I see lots of ’22’s, high optioned 1500’s, with the old interior / dash. The window sticker, below the VIN # says “re-issued”.
Must be built in ’21, re-Vin’d as a ’22. I lost my ’16 2500 HD Duramax Denali, in the middle of a terrible multi-vehicle pile up.
Trying to get back to “normal”. Have a new 2023 2500- HD Duramax Denali on order.. Now putting it off to next July ’23 to get the re-freshed cabin / dash. Said ’23 orders begin 7-27-22. Hope same for 7-27-23. Hate Std. interior colors, Black or Grey-Black, may opt for the Denali Ultima to get Med. Cowhide like a King Ranch I saw.
Last thing I saw standing on my brakes, middle of the pile-up before me, before the air bags lit off, was my ’16 dash board. Do not want to see it again.
FYI All: My ’16 2500 HD, was not pleased with handling from Day-1, with the bed cap & bed slider and tools I carry. Finally put a Roadmaster rear sway bar, 1 -3/8″ dia., Firestone 3500 LB air bags, and Bilstien 6000’s all around. Now was perfect to drive all day long.
If this was a 2500 /3500 HD chassis cab (no box), comes with a huge rear sway bar !! Not even a trailer tow 5Th option from GM with a pickup !! Someone (ahhh, quite a few) are asleep in a few GM departments. Cripes, even a RAM 1500 has a rear sway bar, Nissan, Toyota….Jeeezzze.
I’ve restored ’67 Dodge D-200 Camper Special Crewcab, Dad bought new. added Hellig Sway bars to it when cam available to handle that huge sile in camper. I restored A ’66 Dodge W-300 Power Wagon, Bought a ’73 Dodge B-200 Royal Sportsman MaxiWagon , New in ’73, and put front & rear Hellwig swaybars and Koni shocks on her, to haul a Hammond B-3 organ, Leslie speaaker, and electric piano to gig’s as a teenager. All the keyboards weight ,van drove like a land barge. Suspension add on’s did the trick.
I saved the ’16 2500 HD rear upgrades off my truck as front was totaled. Will fit a ’11 to ’18 2500 / 3500 HD. Putting them on E-Bay. Will not fit my ‘2014. I have been a AWS member and welding and cnc plasma cutting specialist 42 years. Dealt with a lot of large specialty truck mfg’s and shipyards. GM needs to do more with the everyday suspensions and not only the fluff of the AT4X.
Get the HD Re-Fresh out there now please !!
Cheer’s All..
