Chevrolet News:2021 Chevrolet Tahoe and Suburban Debut with Independent Suspension and available Duramax

[Drew Dowdell]

At an event in Detroit this evening, Chevrolet took the wraps off the Tahoe and Suburban SUVs. We don't have specs yet to publish, but wanted to get the pictures out for you to see.  I will be updating the article as more details come out. 

Six different trims will be offered including the new High Country trim, an RST trim, and Z71 becomes its own trim line instead of being offered as a separate package. LS, LT, and Premier trims carry on. Engines are the 5.3-liter and 6.2-liter V8s, but the 3.0L Duramax will also be joining the lineup. The 5.3 and 6.2 now sport dynamic fuel management. All engines send power to the wheels through a 10-speed automatic. The Duramax is available on every trim except Z71.

The power ratings are:

• 5.3-Liter - 355 Horsepower at 5600 RPM / 383 lb-Ft of torque at 4100 RPM
• 6.2-Liter - 420 Horsepower at 5600 RPM / 460 lb-ft of torque at 4100 RPM
• 3.0-Liter Duramax - 277 Horsepower at 3750 RPM / 460 lb-ft of torque at 1500 RPM

The column shifter is gone, replaced with a new pushbutton design placed on the dash.  Thanks to a fully independent rear suspension, they both gain room inside. Magnetic Ride Control and an Air Ride Adaptive Suspension (available on Z71 and High Country) are available. The Air Ride suspension offers adjustable height of up to 4-inches at all four corners .

The dash sports a 10-inch touchscreen infotainment center standard. Buyers can opt for a rear seat entertainment system with twin 12.6-inch displays. Interior room is up; Tahoe sports 40 percent more third-row leg room and 66 percent more cargo volume behind the third row. While maximum cargo room is up 30 percent, the overall length increased only 4 percent. This is done on a wheelbase that is 4.9 inches longer than the 2020 model.  Suburban gets a 4.1 inch increase in wheelbase so that interior cargo volume increases 19 percent while overall length increases 1.3 inches.

Whoa is that a Tahoe Trail Boss???

It's the Z71

[Robert Hall]

Definitely some Silverado influence w/ the front end... 

[ocnblu]

LOVE that Z71, and I applaud the vertical frontal aspect, reminds me of circa 2002, those were some sweet looking Chevy trucks back then.  I am happy the trucks and utilities are re-converging, looks-wise.

[ocnblu]

*grabs chest*  ELIZABETH, IT'S THE BIG ONE... GONE is the column shift lever, replaced by a row of buttons!

[riviera74]

The column shift lever belongs in a 1980s museum.  It's about time it was left behind in favor of push button shifting.  Besides, was push button shifting not available back in the 1950s?

[oldshurst442]

These are nice.

Im on my way in liking full sized pick-up trucks from Detroit...but I never really hated on these. Whether the Chevy or GMC or Caddy versions. I always kinda liked them. This new one seems to be refined more than ever before. And this is just the Chevy...   The Denali and Caddy must really be awesome inside. The Cadillac really has to show up the Navigator because the Lincoln really really upped its game.  And if the Caddy does that, it dont matter what Rolls and Bentley do...the Caddy will remain king of the big SUVs. 

On the exterior, just your basic Tahoe and 'Burban...and that is how it should be.   

 

 

[Robert Hall]

So no 2.7 4 cyl version like the Silverado...

[smk4565]

These seem very carry over so is this new or a mid-cycle refresh?  The body panels on the side look the same, the center console is carry over, engines are carryover with the addition of the diesel.

Independent rear suspension is a big improvement as is the air suspension.  Good adds there.

Front end is ugly on the Silverado, it's ugly here.  I don't think Chevy has made a good looking car since Ed Welburn left, C8 looks good, but outside of that, Chevy builds some of the ugliest cars on the road right now.  

[balthazar]

Prefer the Silverado's nose to the Tahoe, but it looks very fresh & crisp overall.
Every engine getting the 10-spd is good, so is the 3.0TD being available - really intrigued by it.

Completely new platform, and no the console and engines do not carry over. The engines are just the same displacement, they have been updated.

Updated with the same horsepower and torque ratings as the 2014 Tahoe/Escalade, etc.  My 08 Mercedes engine has more horsepower and torque than the 2021 Tahoe from similar displacement.   That 5.3 is almost as ancient as the Tundra 5.7 V8.

Wrong. It just got revised.

[USA-1]

Love that GM is sticking with the SB NA V8's! Cleaner more conservative front end to the Silvy 1500, not crazy about he back-end off the bat, but probably better in person like the Silvy. Inside is a nice improvement and probably what we'll see with the 2021 Silverado/Sierra interior updates. They'll continue to rein in the full-size SUV class. 3.0 DMax is a big add too and continuing to offer the 6.2 in Tahoe is huge. GM has nailed the smoothness and shift algorithms of the 10 speed. Driven a Silverado and Caddy with it now and they were both awesome. Just not crazy about push buttons or dials for shifting an AT into or out of gear.

I have to say I like the front end on these much more than on SIlverado.

Except this trim, this looks horrendous in this color, might be ok on all black truck:

Cool though with the raised suspension, it will have some real off road capability,

Will be interesting to see how they will compare to Fords.

 

Here is a spy shot of upcoming Escalade

Edited December 11, 2019 by ykX

[trinacriabob]

Suburban looks nicer than the Tahoe.  With that little bit of extra chrome, it looks more Escalade grade.

I like the photos of ones that contain some sort of identifiable horizontal front bumper strip.

I'm guessing the independent suspension will also improve the ride on suburban roads and freeways.

History repeats itself.  We're back to transmission buttons up on the dash, adjacent to the driver.  Could a little kid reach over and push "R" when it's going down the road, just for fun, or are there any redundant safety catches?  (I guess the same could be asked of the round dial that sits on the console of Ford Fusions and Chrysler 300s.)

As for the interior, the console is massive, the stitching on seats in some models is always a nice thing to look at, the blend of dark color pieces is less ominous with a lighter interior than they tend to have on lower priced vehicles, the graphics on the IP (slightly slanted speedo and tach numbers) carry on unchanged like those of an '06 Monte Carlo, and, as usual, I don't like the "laptop left open" on the center stack.

I like the center rear graphics ... where they've placed the model names beneath the bow tie.

Good that a 5.3 V8 is standard.  That's a respectable amount of horsepower for the base engine.

But, yes, overall, it's improved.

Not the prettiest thing I've ever seen, especially in Z71 guise. Then again, almost every single thing Chevy has released in the last 2-3 years has looked worse than the outgoing model...and I typically like newer vehicles.

The same could be asked even for a shift lever if that's the case, because everything is electronic and not mechanical any way. I think it's safe to say there are built in safeties but I'm not willing to test it out on my Lincoln.

[David]

WOW 😃 excited for the power trains, independant suspension, suspension options, etc. Much to like here and I think the Diesel will be a Hit here in the Suburban.

Exterior Styling is a FAILURE!, How do they expect to gain market share from #3 place with these hideous looking auto's? 🙄

Guess GM is willing to accept 3rd place behind Ford and RAM over putting a real style into the trucks / SUVs. SAD 😥

If that spy shot is the True Escalade to come, then Cadillac has lost me as a customer as that is as Blah Ugly as the rest of the CUV lineup.

Yes, a long term Cadillac customer that HATES the current styling.

GM truly has lost it's MOJO!

You have to press the brake to shift into Park or Reverse on the Fusion and Chrysler 300s.

The interior looks to be a huge jump from the current models. Very sharp. Now my question is, how in the hell could this interior (or at least a variation of it) NOT be in the Silverado/Sierra?

You really need to start informing yourself before trolling this hard. Everything is completely new from top to bottom.

Wow. If that really is the escalade it sucks. Worse than the chevys suck. Can we assume then the yukon will just have the sierra front on it?

Oddly, it doesn’t bother me. I don’t care for the current gen nose and think the 07-13 models looked better. I do wish they not do a spot on match with the trucks though. At least the last two gens ditched that approach to better results IMO.

So GM spent money to develop a completely new engine that makes the same horsepower and torque as the 2014 engine?  That was a waste of money then.

At first look that new Escalade doesn't look good.  But as I said before, GM design the past 4-5 years is really in a rut.

You do get that its always about bumps in horsepower right? If it happens to way less and the current engine has been updated to make better use of that horsepower, then it is still a solid gain and a tactic that is utilized by all makes including Benz.

 

And again, you talk about looking good or not looking good while not saying a word about the ugliness of your favorite brand (again, looks at the new GLA and holds back vomit).

You only look at the HP and torque ratings?

What about the efficiency numbers?  Dont those count?

I do not know as I havent researched that, but if you are gonna blow your stack bitchin', at least get ALL the numbers so you could REALLY compare and contrast...and when I mean ALL the numbers, I REALLY mean ALL the numbers...

The engine is NOT a completely new design. Like the C8's LT2 engine as compared to the C7's LT1's engine...

Im not talking about the redesigning certain components for the LT2 to be used in a mide-engined configuration, I do mean the small changes to the cylinder heads and valve trains to improve combustion efficiency and stuff...

This new engine under the hood of these new big Utes, If Im correct, use the new LT2 architecture...but they are TUNED to produce the same HP and torque numbers as the previous models...but Im willing to bet that this new engine is MORE efficient in all the efficient ways that are deemed to be...efficient...

C'mon, bro...you are NOT THAT obtuse....

This is just subjective bullshyte.

You are entitled to your opinion, and I WILL agree with you on the last 4-5 years part that GM is bombing in their looks department...

BUT...the Escalade is still under wraps...picture is fuzzy and most of the details of the front end are covered up...

While if the Escalade really does ending up being a scaled up XT6 in the front, Ill agree with you that the Escalade will be dud in the looks department,  but we BOTH cant come to THAT conclusion UNTIL we get the reveal...

So...

 

[smk4565]

Well I hope they found some fuel economy improvements in that 5.3 V8 because there are other vehicles of similar size that get 25% better fuel economy.

That is why I said at first look, and I want to see the full thing in reality.

As far as GM styling, the 6th gen Camaro was a bust, they reworked it a year or 2 later and still doesn't look good.  Blazer looks like the Camaro that was a bust.  The Malibu has been pretty forgettable the past 5 years, the Silverado doesn't look good, that new Tahoe/Suburban don't look good.  I could argue ATS/CTS look better than CT4/CT5, but they are pretty close.  GMC styling has been pretty good, not much wrong there, but Chevy/Cadillacs all look very similar to each other and they aren't on a good track.

I said dont BS me...

The Land Cruiser engine is probably the one that rivals the 5.3 liter V8 in reliabilty...the others not so much...and to boot, you left it as to wonder what engines you are talking about...

In other words...I said to tell me what engine choices and trim levels in hierarchy meaning price tags.......and what HP and torque levels each engine you are gonna hit me with...and lastly...REAL WORLD fuel efficient  numbers...

You just got random numbers going on...

There is a reason why GM is still using the venerable 5.3 liter V8.  Money is a reason. But if it aint broke, and it meets and beats the competition in certain areas, and as a middle engine offering...then no need to fix it...in other words, no need to waste money on engineering and testing a new mid level engine when the one you got is just as good, if not better in some areas than your competition, then no need to change anything...

Its a middle engine choice.... 

It doesnt have to be a better than the rest base engine for entry level stuff nor does it have the pressure to be the top dog engine in being the best of the best as the top dog engine....

Middle of the pack is just that...middle of the pack...and the 5.3 liter V8 is as good, if not BETTER than what the competition offers...which is good enough for the 5.3 liter V8 where it stands in trim level on the Chevy big utes...

GLS last month sold at a higher rate than Escalade has in 59 of the past 60 months.   Only 1 month, but my guess is 2020 sees GLS as the top seller, X7 2nd, Escalade 3rd and Navigator 4th.

True to the Tahoe though (loads of fleet sales due to government and police packages) but they do outsell the Expedition.  I feel like Ford dropped the ball for a lot of years on the Expedition and this new one is a competitor but for 10 years it was substandard.  The Japanese full size SUVs are basically pre-2009 recession designs, those things are ancient and they should just kill them off if they aren't going to come up with a 100% new product.

The X7 has a stated 335 hp/332 lb-ft of torque but they always under rate, and the X7 40i is a full half second faster 0-60 than a 420 hp Escalade or a 450 hp Navigator (both do it in 5.9 seconds)  No way that engine makes 335 hp and moves a 5,350 lb vehicle that fast. 

GLS450 has 362 hp/369 lb-ft plus a 21 hp, 184 lb-ft electric motor.  0-60 in 5.5 seconds again faster than GM's 6.2 V8 while beating the 5.3 in fuel economy. 

Expedition has 400 hp/480 lb-ft, 0-60 in 5.7 seconds.  Still faster than the 6.2 Tahoe, but better fuel economy than the 5.3.

Car and Driver's real world highway fuel economy for GLS was 24 mpg while 28 mpg for the X7 and 20 mpg for the Expedition.

Goal post moving doesn’t change the fact that the Escalade has routinely outsold the GLS. Your future guessing will not change that fact with these new models coming out, they will continue to sell well and routinely outpace the competition. 
 

And you have a lot of nerve holding fleet sales against GM while Mercedes whores out as many E Class taxis as they can produce and the sheer number of fleet sales of the S Class is equally staggering. When Benz does it, it’s good. When GM does it, it’s bad. 
 

Just more of that fanboy “logic” I guess.

Comparing the Tahoe's 2020 numbers is irrelevant. The new 5.3 and 6.2 have new cylinder deactivation tech that allows the engine to run on as little as 2 cylinders and start/stop. The numbers will change.

Right so 20/25 is the leader in the clubhouse for full size SUV gas engines.  Which is why I said GM should aim for a 20% bump from current Tahoe.

Uh oh, my bro may have found a replacement for his 2017 Tahoe (with 80k + miles on it already) just might have a Duramax 2021 Tahoe in the family.
