A slew of next-generation SUVs are headed down the pipe, with the all-new 2021 Chevrolet Tahoe and 2021 Chevrolet Suburban both slated to drop cover on December 10th.
The all-new models will ride on the GM T1 body-on-frame vehicle platform, the same architecture used by the 2019 Chevrolet Silverado 1500 and 2019 GMC Sierra 1500. In addition, the 2021 Chevrolet Tahoe and Chevrolet Suburban are expected to come equipped with aluminum swing panels (hood, trunk, doors, etc.), which will pair nicely with the T1 platform to help shed some serious weight compared to the current models.
As we reported previously, the new SUVs will both come equipped with a new independent rear suspension setup, either as standard equipment or as an available option. Not only will this give the 2021 Chevrolet Tahoe and Suburban significant improvements to both ride and handling, but it will provide the SUVs mechanical parity with rivals like the Ford Expedition.
As for what will be mounted under the hood, we expect the 2021 Chevrolet Tahoe and Suburban to offer the turbocharged 2.7L L3B inline four-cylinder, and/or the naturally aspirated 5.3L L84 V8. As for cog-swapping duties, we expect those to be handled exclusively by the new GM 10-speed automatic transmission.
Per usual, the next-gen models will also come with completely new designs for both the exterior and interior. As we covered previously, these will come with an “exceptional attention to detail” that includes new fascia and lighting treatments, plus improvements to third-row seating. What’s more, the front ends will come with front air curtains that will make the SUVs more efficient with the go-juice.
We’ll cover this story further as it develops, bringing you all the latest as soon as we get it, so make sure to subscribe to GM Authority for more Chevrolet Tahoe News, Chevrolet Suburban news, Chevrolet news and around-the-clock GM news coverage.

Can’t wait to see the new lineup!
Chevrolet designed the new C8 Corvette; but yet Chevrolet has failed to keep up with the competition and integrating some performance to their full size SUVs, why not make the 650 hp supercharged 6.2L V8 available in the Chevrolet Tahoe and Suburban, they can try it as an experiment and if there aren’t any buyers.. they can scrap it in a couple of years.
@omegatalon Dude you are completely ignorant for what you said. Gm is doing great with the competition. Yes, it would be nice to have a 650 hp engine in a suv, but its not enough to actually help them compete.
I’m excited about this SUV! Loved the current gen Suburban/Yukon XL! Awesome all around vehicle with surprisingly good fuel economy.
I guess they didn’t learn the air curtains are more show than go
I really hope they didn’t do the fish gills treatment they stuck on the Silverado. That single design element ruins the entire front end. If they would have just given the Silverado a full front bumper and no fish gills, I truly think it would be one of the best looking Chevy trucks ever built. Air curtains done right are nicely hidden and integrated to the front like on the F-150 and Sierra. Chevy sticking them on the sides of the fenders and cutting the bumper short to do it is just pep boys tacky and frankly bizarre. It’s like two big hood scoops Joe Dirt would glue onto the sides of his truck because he thought it would look cool to his trailer park buddies. Chevrolet should be above that nonsense. If they Did do that to the Suburban/Tahoe, that will be really sad.
honestly I like the new silverado and I think that its selling extremely well considering the front end look. So I have no idea what your problem is with it.
The official reveal for Chevrolet’s BOF SUVs are right around the corner. Can’t wait to see them unveiled!
GM PLEASEEEEEE give us the 3.0 I6 Diesel in at least one of these models. Please!
Yukon AT4 with 3.0 I6!
If they offer the diesel, I will for sure will wait for 2021 Suburban. If they don’t, then 2019 or 2020 it is.
I’m sure GM will disappoint me once again though. I’ve been waiting for them to put a diesel in these since the 6.6 Duramax was first introduced.
I just wish the Expedition offered a diesel so then GM would follow.
Although I’m huge on GM, especially Chevy, I may check out an Expedition if these new ones aren’t worth waiting for. Currently have 2016 Tahoe, love it but some things need changed and offered.
Sure the turbo 4 cylinder has about the same amount of torque, but it is an image thing. Anything less than 400 pounds feet of torque means you can’t pull more than a 2,500 pound trailer. Who wants to spend $55,000 and get a 4 cylinder in the largest SUV’s in the market? Maybe the editors are not old enough to remember the V8 juice ads from a few decades ago…”Wouldn’t you rather have a V8?” Of course you would…..LOL
I’m they kinda guy who would like a turbo 4 in a suburban. My first and last suburban was an 01 with 288 hp, about the same as the truck 4.3 v6. It was plenty of power. Since then these things have become too expensive, even used. I hope they make a “custom” trim like the truck with the 2.7 that has a under 40k MSRP. I wouldn’t mind the cloth nor the 2.7 motor.
I’m thinking the 2.7 is the base motor on the 2wd Tahoe and the 5.3 is the base on the Suburban.
I literally laughed out loud when I read “Anything less than 400 pounds feet of torque means you can’t pull more than a 2,500 pound trailer.” I’m old enough to remember when fuel injection was added to the Chevy p/u truck line (calendar year 1986) and it raised the torque output of the 454 to 385 lbs ft, which was higher than Ford’s 460 of the era, as well as anyone’s diesel in a pickup.
So…you’re saying a one-ton duality with a 454, a TH400, and a 4.56:1 axle is a max 2,500 lbs tow vehicle??
Yeah, or last year’s 6.0 Vortec ahahahaa
Man I hope they shove that Duramax 3.0 in these…at least the Suburban…
I hope the awful front-end styling of the 2019 Silverado is not carried over. I also hope that the console-delete option remains.
As for the four cylinder engine: I doubt the take rate on these will be sufficient for them to make it to the 2022 model year. It may be a highly competent engine; I don’t know. But, as stated further up, it’s an image thing. Also: how is this engine doing out in the real world, in pickup truck service? What is the real-world fuel economy?
Please hurry up can’t wIt longer.
The Cadillac and then GMC and Chevy….
These SUVs start around 50k, even if buying the cheapest, I sure wouldn’t want to get a 4cyl when spending 50k+ for a full size SUV.
GM should of offer 5.3, 6.2, and 3.0 diesel.
Interesting how the outgoing full sized SUV models have continued to sell well in spite of all new Navigator and Expedition being out for near two years. This year the discounts have increased some, but sales volume has still remained very good.
The reveal for the outgoing current Tahoe was back on September 12th, 2013.
The best SUV is about to get even better!!! The small complaints that people are just people being over picky with their attempts to bring it down.
As long as Mary “no style” Barra designed it.
Yes, because we all know Mary works in the design studio.
I’m with everyone else here, the excitement for these products I think is strong… I hate to use the words, “I hope” because everysingle time the launches have been underwhelming. Recall the Suburban’s weird front 1/4 panel spears. However the pricing and most of all the interiors are my questions….yes and the 4 cyl… It would be nice if its a no cost option so they can see what the market wants vs std 4 and everything else is extra cost options. You know it’ll come to the point where folks arent going to pay extra, they’ll go elsewhere…
I’m fine with the 4 cylinder as standard and the v8 as optional if they can make a ls or even custom trim that starts below 40k. Remember that the 2019 Silverado LT starts over 1000$ less than the 2018 with the 4 cylinder. Make it the budget option, not the v8 the premium. I want a suburban bad! But I can’t afford new or even the used ones as loaded used suburbans are all shot or still pricey.
Nothing will be cheaper because they used a DOHC, 4V, turbocharged 4 cylinder in lieu of a simple pushrod V8 like a 5.3. If you go to a GM parts catalog, the 4 cylinder is more expensive than a 5.3. The 4 cylinder turbo engine is too complex and has too many parts and pieces to be cheaper to produce than a 5.3. The $1,000 less on the ’18 vs ’19 Silverado came from somewhere else.
Maybe they’re collecting real world data with the 4 cylinder to see where they can go with it in the future, because there’s no practical or logical explanation for using it in the pickups now – it’s costlier to produce, doesn’t improve fuel economy, and makes noticeably less power and torque. I’ll give you that it’s easier to “tune” for more power and torque, but who wants to “tune” a new, $40-50k truck (and kill the powertrain warranty) just to get to where the 5.3 already was?
Where is your parts catalogue? A 4 cylinder dohc is the same difference as a cam in block pushrod, minus additional parts for 4 more cylinders. The additional parts for a dohc v8 is that there are 2 sets of dual cams and timing chains. Gm small blocks and i4 cylinders both have one set of dual cams, but the i4 doesn’t need additional pushrods, but it does need room in the top for the cams making it taller. It ultimately has less parts because they have the same number of cams(2) but less pistons and a simpler to cast and machine block.
I’m going to try my best to decipher your questions and comments…
“My” parts catalog is the GM Performance site; you can find it at Chevrolet.com. Additionally, many retailers (Summit, Jegs, etc.) retail the GM crate engines.
I don’t have the time or space here to point out all the things wrong with the next few sentences, but I’ll hit some of the high notes:
– No 4 cyl. DOHC is the “same difference” as any pushrod V8.
– No GM small block V8 has EVER had a “set of dual cams.”
– OHC engines, whether dual or single, do not have pushrods. I think you were saying they have fewer pushrods, but I’m really not sure.
But, the whole point of my post was to say it’s cheaper to manufacture a pushrod V8 than a DOHC, 4V, turbocharged I-4, and to prove my point I simply searched “GM crate engines.” The LTG, a turbocharged 2.0L I-4, can be bought retail for about $8,600. It is NOT as complex as the 2.7 in the trucks, as it doesn’t include the “Tri-Power” triple feature camshafts and operating accessories. An LS3, as in 6.2L, large port, offset rocker, 436hp Corvette engine can be bought retail for about $7,100. The pushrod V8, that’s an upgrade from the truck 5.3, is $1,500 cheaper to buy that the 2.0 turbo-4, that’s less complex than the 2.7 truck engine.
The 2.0 ltg cost gm about 2000$ to install brand new. They are free to charge what they want for a crate engine. Likewise the ls3 isn’t in as high demand as it once was since the development of the LT line and it’s bigger brothers, LS7 and LS9. To move an LS3 crate it’s has to be a bargain over the other motors. If I had to guess why the LTG cost so much as a crate it’s because packing. You pay for a smaller engine for where you couldn’t fit a big block, like the cheap turn key 350 options from Chevy performance. Small block motors originally had one cam in the block, for both intake and exhaust, just as many older 4 cylinders were sohc, now all 4 cylinders are dohc, and smaller blocks are duel cam in block, because of variable valve timing. You need to be able to control the two independently.
Yeah, okay…I hope they aren’t drug testing at your job tomorrow.
Goodnight, Felicia.
So my issue is Trunk space. I still drive 2013 Suburban cause I calculate trunk space with all the seats UP.
Consider this Trunk space with Seats Up.
2013 Suburban. 45.80
2020 Suburban. 39.30
2020 Expedition Max 36.00
I am waiting for GM to fix the stupid slant / inclined trunk. You put Luggage in and things slide down. Yes there is storage at the bottom…but no I don’t want to store and carry my WD40 with me all the time.
Unfortunately, looks like GM is competing with Ford. Their new trunk is even slower than current Suburban. So I might be screwed with new model and waiting for nothing. Just don’t know how long my 2013 suburban will last.
How long your suburban will last? Its 6 years old!!! If you were talking 12 or 16 years old you might have a point but 6 years is not old for a suburban.
Yes!! Expect another 5-7 years out of the car, especially if you dont drive it like a moron or like its a little car!! Those 5.3s are bulletproof!! The only bad part about those are the tranny!!
God Bless America!!
Please be a diesel, please be a diesel, please be a diesel!!! PLEASE GM, DIESEL SUBURBAN AGAIN!! 3.0 liter i6 for the win!! #MAKETHESUBURBANDIESELAGAIN
#MAKEAMERICAGREATAGAIN
#KEEPAMERICAGREAT
God Bless America!!
Looks like I’ll hold off on getting a 2020 Suburban. Hopefully this next-gen Suburban will be worth the wait.
Waiting to see the new Yukon AT4 with a Diesel. I really love the way the current truck looks (Dont mess it up), and want to take it to Canada for overlanding.
K5 blazer- Tahoe sized with truck suspension and no 2wd. 5.3, 6.2, 3.0 diesl, 454 (for SS)
Tahoe- current suburban with 454 ss
Suburban- HD Tahoe
If the reveal is December 10th when would it be expected to be available at dealerships?
I would like to purchase a Chevrolet Suburban 3500HD with the new 6.6 liter gas engine. No one can give me a answer if and when they will be built.
