2027 GMC Sierra: Official Discussion

[Zane]

 

It's official. GMC pulled the covers off the next-gen 2027 Sierra 1500, and we got the first official look.

Full breakdown here: https://www.gm-trucks.com/next-gen-2027-gmc-sierra-1500-v8-trim-changes/

 

The quick hits:

• SLE and SLT are dead. The new core retail trim is just called "Elevation".

• Two new V8s, a 5.7L and a 6.6L built with high-performance Corvette architecture roots. No horsepower or torque numbers yet.

• The 2.7 TurboMax finally ditches the old gearbox and gets the 10-speed automatic.

• AT4X moves to larger standard 35-inch tires with front and rear e-lockers, Multimatic DSSV dampers, and heavy-duty Jounce Control Dampers.

• Over 60 inches of combined display on Denali Ultimate and AT4X, complete with a motorized articulating center screen and an adaptive passenger screen.

• Seven simplified trims across the entire model line to clean up ordering confusion.

 

So let's get into it:

• New 5.7L and 6.6L gas V8s with custom active exhaust tuning and a Corvette connection. Is this the exact engine lineup half-ton traditionalists have been begging for?

• Purging the iconic SLE and SLT names after all these years to lean entirely on Elevation as the high-volume core. Bold move, or a mistake?

• That motorized articulating 16.3-inch screen that slides up to reveal a hidden dashboard vault. Awesome mechanical theater, or does it make you nervous about long-term durability?

• Physically lowering the headlamps in the front fascia to improve road courtesy and stop blinding oncoming traffic. Smart real-world engineering, or does it hurt the truck's aggressive stance?

• What trim are you putting your name down for on day one?

Drop your first impressions below.

I could be interested if they axed cylinder deactivation and at least have a button for stop start. I’m sure the HP numbers will be higher. I would want a longer warranty to help build confidence. I’m a less is more guy as I get older. A V-8 work truck model would be my choice. I know a few outfitters for custom additions I prefer.

Not sure about DFM tech but i know there's a stop/start deactivation button.

Gotta say the Silverado wins in the exterior looks department, in my opinion.

Exterior and interior, not impressed. That dash is just plain lazy, no effort in design.

Gen 6 V8 will have AFM and or DFM.  The first engine detailed of this is the LS6 which is confirmed to have AFM from the Corvette Museum Bash sessions.

I may be old school. But I’ll pass. I’ll stick with the old stuff. Thank you.

- I like the outside but not as much as the Chevrolet.  They ICE'd the EV styling and it works, but I think exterior goes to Chevy on this one.  

 

- SLE and SLT dead = Not.  Surprising.  Fits into the rest of the GMC lineup like this which (aside from Pro) matches the rest of the family.  Elevation, AT4, Denali.  

 

- Interior.  Sophisticated Malaise era.  Why do I say Malaise?  Drawn with a ruler.  Rectangles everywhere.  Looks very premium though.

No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.

 

The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.

 

The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.

Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.  

 

Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.

Follows the motif on the Sierra EV.  Satin finsh to the lower bumper area, painted above:

 

Elevation

I'm very interested in what type of cylinder deactivation GM has come up with. It can't possibly be the same as the current gen 5.3/6.2!!!  That would be a disaster. I am in the market, but I'll need some pretty convincing positive reviews on these engines before I commit to a $70,000-$80,000 truck! (Almost bought a 2500hd AT4 6.6 gas this week. But I decided to be patient and see what develops with the new V8's).

Agreed, it definitely appears to follow the EV motif, especially because it appears to follow the rockers on the Sierra too.... but has to be a cost saving measure as well.  Between rocks and bugs and driving 20K+ a year on Texas highways, I can keep the painted front ends looking decent with PPF and a thorough periodic cleaning, but the unpainted plastic cant be coated, or cleaned up well.  The same plastic underneath the bumpers on all our current generation trucks is beat to hell after 2 years or less on the road.

Oh yea, cost cutting for sure but its driven by market shift.  Less and less people want chrome, and chroming costs more than painting.  

 

There are coatings that work with unpainted plastics.  Adam's Graphene works.

I didn’t have trouble keeping the plastic on the old 2002 Avalanche looking new. Every three months treatment took about 15 minutes. It was a lot of plastic.
