General Motors is currently considering an expansion to the availability of the naturally aspirated 6.2L V8 L87 engine in the automaker’s all-new full-size SUV lineup, GM Authority has learned. According to GM Authority sources, GM may offer the 6.2L V8 L87 on additional trims for the new Chevy Tahoe, Chevy Suburban, and GMC Yukon/Yukon XL.
Currently, the 6.2L V8 L87 is only offered on a single trim level for the new Chevy Tahoe, Chevy Suburban, and GMC Yukon/Yukon XL. More specifically, the engine is equipped as standard on the 2021 Chevrolet Tahoe High Country, 2021 Chevrolet Suburban High Country, and 2021 GMC Yukon Denali/Yukon XL Denali. Critically, the 6.2L V8 L87 is not offered on any other trim level in each of three nameplates mentioned, not even as an option.
The rest of the trim levels for these three full-size SUVs come with the naturally aspirated 5.3L V8 L84, while the 3.0L I6 LM2 turbodiesel Duramax is also offered on most of the trims. The 6.2L V8 L87 is the most powerful engine of three, producing 420 horsepower and 460 pound-feet of torque, as compared to the 355 horsepower and 383 pound-feet of torque produced by the 5.3L V8 L84, and the 277 horsepower and 460 pound-feet of torque produced by the 3.0L I6 LM2 turbodiesel.
| Engine | Power (hp @ RPM) | Torque (lb-ft @ RPM) |
|---|---|---|
| 6.2L V8 L87 | 420 @ 5600 | 460 @ 4100 |
| 5.3L V8 L84 | 355 @ 5600 | 383 @ 4100 |
| 3.0L I6 LM2 | 277 @ 3750 | 460 @ 1500 |
It’s currently unclear when the expanded availability of the 6.2L V8 L87 gas engine will go into effect, or which trim levels in the new Chevy Tahoe, Chevy Suburban, and GMC Yukon lineups will get the revised engines structure.
As a reminder, all three full-size SUVs were overhauled for the 2021 model year, riding on the all-new GM T1 platform and offering revised styling, a new interior design, and the latest technology.

2021 Chevrolet Tahoe/Suburban and GMC Yukon may offer the 6.2L V8 on more trims means the lines that separate them and the Cadillac Escalade is blurring even more; this is why Cadillac needs the 650 hp LT4 as an engine option for the Escalade.
No, you can already get the 6.2 in the Tahoe and suburban and Yukon. The Escalade should have arranged topping powertrain, but that’s for Cadillac to figure out. The Tahoe shouldn’t be artificially suppressed because Cadillac doesn’t want to put in a better engine in the Escalade
Cadillac would be better suited with the powertrain that’s coming in the new Hummer EV
I take this to mean another, higher-end engine is about to be offered in at least the Cadillac, and possibly the Denali, as well. GM is so married to tiers they would never open the 6.2 gates to the common folk if they didn’t have something else they can’t have in its place.
My thought too. Maybe a cross plane version of the 5.5DOHC
When is GM going to crank up production…..there is NO real inventory of Yukon’s with in 100 mile radius of NYC.(as of this morning only 268 vehicles)…what gives with production….two dealers told me to order what I want (no allocations available), come back in January or February….
Is GM going to do anything about the embarrassing start up squeal on there new 6.2 models, or are the just going to blow customers off like they have on 6.2 trucks with” they all do that,” with repair offered on there $60,000 trucks

Please make the 6.2L available in the RST 2WD Tahoe
All I can say is; if Biden-Harris get in the White House – wave good bye to any V-8 engine. It would be odd if GM didn’t offer the 6.2L in the same trim lines as the Silverado and Sierra like the RST, AT4, or a ZR-1 off road package. All Cadillac needs to do is put a super charger on it to one up Chevy and GMC.
I would buy the Premier if available with 6.2L engine. In the meantime, I review the large SUV options each week.
For any Tahoe product managers wondering why someone would prefer Premier over Highland, its the ride. I prefer the 20 inch wheel with taller 65 series sidewall to absorb road bumps. Its much nicer for highway driving. I have two kids away at college and the third is a one year away. GMC Yukon/Denali use 65R20 tires, but I prefer the Tahoe appearance.
My plan is to buy a Yukon AT4 next, with that being said I would love if they offered the 6.2 in that package. They really do need to boast the horsepower of 5.3 V8, it’s due for an update.
