2021 Suburban-Tahoe

[boatpi]

DIESEL finally, Colorado diesel.

 

[rush1]

I absolutely love Suburban /tahoe, yukon/escalades

 

[caribbean20]

FINALLY an independent rear suspension. Geez, did GM ever milk that truck platform for years.

 

[WYRD]

Gunna push toward 100k

No, that’s not going to happen... We are looking forward to the 2021 GMC Yukon’s and the 2021 Escalades.

I wish the diesel had a bit more power, in the Tahoe, fine, but a Suburban is heavy. Has same torque as my RRS, and it weighs 4,500 dry. I get 28 in town, and 30-34 on the road.
A diesel engine is an interesting addition to the lineup, and it's the same turbo-diesel 3.0-liter inline-six found in the Silverado. Here, it makes 277 horsepower and 460 lb-ft of torque, and it could achieve a 30-mpg highway EPA fuel-economy rating if it can come close to the Silverado's numbers. We found this engine to be smooth and quiet in our testing of a four-wheel-drive crew-cab Silverado, and it achieved a 26-mpg result in our 75-mph highway fuel-economy loop. The Duramax will be optional on all Tahoe and Suburban trim levels except for the off-road-focused Z71.

It’s too bad that GM didn’t put the Tahoe/Suburban dash in the LTZ equipped trucks. The new interior and dash in the new trucks is hideous and I’ve been a hardcore GM guy.

These look amazing! Perfect timing - My wifes Grand Cherokee will be paid off the end of next year, so this will be our next River Shuttle

There’s a mid-cycle interior redesign that supposed to be coming to the trucks very soon [emoji106]

They better hurry. That F350 Tremor is looking wayyyyyyy better in and out.

 

[boatpi]

Jeeps new Grand Waggoneer will be out next year, I bet based on the RAM 1500 like the Jeep Gladiator.

 

[Bigbore500r]

They better rush these to market before the home equity bubble pops.........
Get some quick sales at $80k a piece im sure

 

[Bowtiepower00]

When I heard the new gen Tahoe was going IRS, it was all I needed to hear to go and purchase a ‘19 Tahoe for the old lady’s DD. Call me old fashioned, but I prefer a solid axle in the back. Bought a ‘11 4x4 new, and it was a great rig. No complaints with the ‘19, went 2WD this time, but kept the towing package to get 3.42s and brake controller.
Really wanted the 6.2/ 10 speed, but they were impossible to find and $$$$$... 5.3 and 3.42s runs well and maintains 4cyl mode on flat ground at 75mph for 20-22 highway at interstate speeds.
I will be watching the new diesel model with interest. Plan on keeping the current ‘hoe for quite awhile, but if the new diesel pans out I might consider upgrading in 4-6 years. We will see what real world mileage vs. maintenance costs end up at...

 

[BoatCop]

I'm down-sizing. Don't need the room of my '16 Tahoe any longer. Got this on order. Should be in by Christmas.

2020 Acadia Denali - Fully packed.

Still have my Sierra for towing and the boat. I think I only towed with the Tahoe a couple times in 3 years.

I’m still waiting for any of the big 3 to put out another Excursion type SUV, fullsize 2500-3500 diesel with enough GVWR to actually tow something. I’m sure it will be 75k, but I’d still be a buyer.

Public sentiment killed the Excursion, and government regs basically make it difficult for carmakers to market these vehicles to the public.

But you can absolutely get a 3/4-ton Suburban from GM - they market and sell them to fleets, and they’re pricey.

They also aren’t available with the Duramax [emoji107]

I am fully aware of the reasons for the X’s demise, and have spent plenty of time on the GM fleet site configuring the 2500 SUB, but, for my use, it would need to have more than 3500lb towing (I’m not building a bulletproof SUV) and would need to have a diesel and a GVWR over 10k so I could tow a decent size Toyhauler, legally. I know that will probably never happen, but if it did, regardless of manufacturer, I would be a buyer, even at a price WAY higher than I would be comfortable with. Until then, I’ll keep my Ram CTD, lol.

I wonder why the tow rating of the “Suburban HD” is so low?

GVWR and payload are decent...but a 3,000 lb tow rating is silly.

I’m sure you already know. But IMO its to accommodate armor upfits for government work. No other reason in my eyes why payload and towing have such a difference. At any rate, without a diesel, or at least a SOLID Big Block type engine option it’s a no-go for me. If a suburban with a big towing capacity and a decent gas option were available now I would have ordered it, lol...

 

[pronstar]

I could be mistaken, but I recall reading that the Suburban HD doesn’t come with a hitch receiver, so your hypothesis makes sense [emoji106]

I don’t get that.....a lot of people buy SUVs to tow....makes no sense. And the should offer the 4.10 rear end.

It’s the pussification of trucks and SUVs brought about by Obama when he BKed GMC and went all crazy on the “climate change” scam.

They don’t want us to have big gas engine boats and off road toys.

With 8 speed+ transmissions a 4.10 is history.

Wife needs a dog and grandkid hauler and that is more appealing than the Honda Pilot.

 

[TPC]

I believe what was standard one year is often an option the next so the base price remains the same or close to.

Several things that were standard on our 2015 3500 Denali are now options.
But we're told no price hike for 2020!

That's insane. The Acadia (3.6 6 cyl, 9 spd trans / AWD, 3.49 rear) I ordered with the "Trailering Package" (receiver, additional trans and eng cooling, 170 amp alt, etc) is rated at 4,000#. I wouldn't tow that much any distance, due to the relatively small wheel base, but still........................

Hell. I did launch and recover my 22' pontoon with my Jeep TJ. But that was only a 2 mile drive to the Casino launch.

Boatpi beat me to it. The new transmissions have such lower and tighter gearing that there is zero need for that much gear reduction. The 3.42's are pretty much the 4.10's of previous generations.

FINALLY an independent rear suspension. Geez, did GM ever milk that truck platform for years.

So, 85 years of a straight axle means nothing? Apparently they fucked up. For 85 years.

Next hot item with be a straight axle kit for front and rear...

You want a car? Get a miata...

The title says “Suburban-Tahoe,” NOT “Truck.”

If I want a truck, I’ll buy a truck. Suburban-Tahoe are SUVs and must compete with other better handling competitors ALL of whom moved to independent rear suspensions years ago.

Suppose you’re still mourning the Mustang’s move away from a solid live axle . . .

Just bought this brand new 2019 Denali for $66,500 with all the rebates. I'm happy.

Lots of people buy Tahoes and Suburbans for towing. I think the independent rear suspension is not going to do well for towing with very much tongue weight. Anybody have opinions on towing with and independent rear suspension??

Also, independent rear suspension is going to give you twice as many things to go wrong on the rear end

Towing with IRS isn’t really an issue, provided your vehicle is setup properly [emoji106]

Proper setup = load-leveling/airbags

Unlike a live axle, which has geometry that doesn’t change under load / as it cycles, an IRS has significant geometry changes under load / as it cycles. So it’s critical to maintain the stock ride height regardless of load.

Any carmaker’s towing package for an IRS vehicle is gonna have bags or something else (like load-leveling shocks) to maintain ride height.

Thanks, I don’t know much about IRS, but it seems like if you overload the rear end, the axels are going squat out. So I guess load leveling and airbags would fix that. Good info. I’ll keep my 2500 HD Crew, works fine just stock.

Do you think that 8 speed tranny and 3.42 are going to last as long as my 4 speed tranny and 4.10 year end? I’ve got 190,000 flawless miles on mine. I don’t give a shit about a couple miles per gallon, I like going up an on ramp and being at 90 mph before I merge on the Interstate and cruise at 80 and 2700 RPMs.

Time will tell. One main benefit is higher cruising speeds at much lower rpms. I run 80 at 1700 rpm. 85 at 1900. Still getting 19mpg. 4wd, 3.42's, leveled 33's.

We had an ‘11 Tahoe we bought new as a DD until ‘16. Tried downsizing to a couple of Jeep GC’s, but they didn’t compare to the Tahoe. When I heard the new SUVs were going IRS, we decided to pick up another Tahoe before the update. We are back in a ‘19 Tahoe and couldn’t be happier. Even with the solid axle out back the ride is excellent. No other brand makes an SUV that compares to the offerings from GM, IMO.

I will be watching the new model when it comes out, but plan on holding onto ours for awhile.

I’ll let others be guinea pigs for a few years before I take the plunge.

The 8 speed, maybe not. One of the reasons it's being phased out by the 10 speed. Yes I believe the 10 speed will last behind a small block. They are putting it behind the new Duramax and the new 7.3 Ford gasser so I bet it'll live. And also, you're just referring to final drive ratio for acceleration and the 10 speed with a 3.42 has a much tighter ratio gap as well as being similar overall ratio so the acceleration will also likely (I don't know the exact numbers to say for certain) be quiet faster everything else being equal. It's really the same argument as the 3 speed with 3.73's and a 4 speed with 4.56's. except the 4 vs 10 speed discussion is literally comparing a TH400 to a cutting edge transmission designed to live behind big power.

My question is how well will these transmissions hold up vs. the old technology of rear gear ratios?
I’m thinking rebuild costs will be in the Allison rebuild price range ?

They better hurry. That F350 Tremor is looking wayyyyyyy better in and out.

I’ve always been 100% Chevy, until 2019! Chevy sent the Silverado down the Tundra and ruined the front, and Ford hit a Homerun at the same time. If i was buying it’d be the F250 right now.

Since they are designed to be a very robust trans with a multitude of applications ranging from the new Duramax all the way down to a Camaro and the new Ranger.... I think they'll hold us just fine. Shit, both Ford and GM are putting this 10 speed in damn near everything. Also for that reason, rebuild costs may be held in check.
