2019 GMC Sierra 1500 AT4 Review: The Most Powerful & Capable Half-Ton GMC Ever? 

Awesome review Andre one beautiful truck and that exhaust rumble sounded like a high performance engine ..

Never heard a better sounding stock exhaust on a pickup

Highly motivated, truly dedicated, rough, tough, cant get enough, twisted steel, sex appeal, lean mean off road machine. ANDRE IS AWESOME!! Hey, cool truck too!

Man that 6.2L sounds nice....

Man that V8 just gave me goosebumps. I love the sound🤤😍

Looks good, sounds good. Lots of cameras but I'd like to see one more; a built in dash cam.

Great review as always Andre! Nice truck, for a GMC. Man I can’t wait until Its warm enough so that I can wear t-shirts outside. 🇨🇦

Those complaining can't even afford a 90s Toyota Corolla

Still love this truck. I just hate how much it costs. I would probably do aftermarket parts mainly because I would want a more subtle but throaty exhaust as that one is a little too high pitch for me.

TFL was in San Diego and I missed them, wished I knew they would be up on my local trail, I would have been there to check it out.

Wating for testing sierra HD AT4

You re looking much more relaxed Andre doing the review all alone! Great video!

Shop around, they arent that much. I just bought my 20 AT4 and didnt pay even close to what msrp on these trucks. There are deals to be had. Love my AT4!

Nice review. I’d like to see a full OFF-ROAD comparison review, between AT4 vs RAPTOR vs POWER WAGON

Love exterior of GMC I just wish had better dash like RAM, love. 6.2 V8 sounds👍Great vid👍

Finally they offer an off road package with the 6.2. Might consider GM now

Now THAT exhaust sounds like Merica! Like a damned nascar cup car! WOW! I am ready to sell everything I own to buy one of these!

I love the look of the truck, however I don’t see the value for what you are getting. I’d need to get 5-10k off msrp.

Man I can't wait for the Rebel TRX. The comparisons will be epic. TFL needs it as a long term when it comes out

Great, High quality video Andrew and the rest of the TFL crew

I didnt know off road was all about cameras and cubby holes 👀

I Loved That High Output 6.2L Big Boy V8!

I believe that’s the Borla exhaust they use. 👍🏽👍🏽

Didn’t look like there were any skid plates under the transmission or gas tank.

The truck sounds great. Similar to the SS 1LE my friend has with magnaflow exhaust.

Rancho shocks!!! Pure orgasmic delight!!! Hey GM, 1985 called and it wants those shocks and instrument cluster back.

I would venture to say that the AT4 exhaust is on par with the Tundra TRD Pro. Pretty impressive fuel economy that 6.2 gets as well. Awesome video Andre!

I love it when Andre does a review.

Great review Andre. It would be a worthy note that the 6.2L V8 in the Sierra/Silverado requires premium fuel (which costs about a dollar more per gallon in the Philly burbs at this time/60 cents more per gallon in other parts of Pennsylvania) while the FX4 package Ford trucks only run on 87 Octane fuel. The Hemi V8 in the Rebel also requires mid-grade (89 octane) fuel for reference. That savings at the pump could easily pay for a 2" leveling kit and some aggressive 33" tires.

General Motors needs to start putting the 6.2 in the lower trims

Seems like GMC could add that performance pkg much cheaper because they are not supplying the original parts.

Can't wait to see the 2500 HD review 😀

Great work Andre!

For that price you get Ranchero shocks?? No way!

I hate how that’s considered a descent off road corse/trail. It’s just an easy little trail that most 4x4s can go on with ease.

Not sure why I’m interested in this badass truck !! I’ll never afford to own !!!

Nice review as usual Andre. That performance package should be standard. The GMC is overpriced, that’s why I went with Trailboss. People say interior is crap blah blah. They just can’t afford one. The interior is great actually. I don’t need massaging seats and built in makeup applicators. And no I don’t need a 20” monitor.

once they get the composite bed i will be seriously considering the AT4

That exhaust sound at 4:40 😍😍😍

You can get an AT4 crew cab with the 6.2 v8 & 10 speed for $53k if you don't add all the tech. It's still crazy expensive but at least it's not $67k. Also, in 2020 you can get the 6.2 v8 on the Chevy Trailboss for $43k.

Probably the best 1/2 ton truck currently available.

What a good looking truck. Perfect for my use, boat, Travel trailer, hunting and fishing. Thanks gents!!

You can get this truck for $57,350 at a lot of dealerships right now for $57,350! OR you can get the GMC 1500 Denali right now for $57,948!! I want people to put this in context! The AT4 is a 5.3L V-8 4Wheel Drive. With a nice set of upgraded off road tires and wheels as well as an upgraded suspension. Spray in bed liner with that new fancy tail gate that opens a bunch of ways. All Leather Interior. A BIG back seat with the 4Door that has all the room you need. Upgraded exhaust that sounds really good. It has OnStar and all the extras you would want. This is the AT4 model for $57,350. Now you think I'm some GM lover trying to push their vehicles? NOPE! I have NEVER owned a GMC. The point to this is that I can go buy that truck RIGHT NOW!! With all those extras for $57,350. OR I could go buy a Jeep Gladiator v-6 it will haul less, tow less, ride worse, burn more gas more than likely (FCA lies a lot about mpg's) It will carry fewer people, it's warranty does not match the GMC, It is slower than the GMC, Does not sound as good as the GMC and it doesn't have nearly as many extras as the GMC and I am going to pay $65,000 for the Gladiator!!!! Loaded the MSRP is $62,000. The Gladiator is new so NOBODY is going to be selling them that cheap. They will be at least three thousand over the MSRP!! That is $65,000! First thing people will do is put bigger tires and wheels on it and get a lift kit dropping the mpg to probably around 15 mpg on the highway to the GMC 20 on the highway. Now your in about $70,000 for the Gladiator!!! OR the GMC AT4 Double Cab 4wheel drive Leather Interior decked out at $57,350!!! The GMC despite being an upgrade in every way is $12,650 CHEAPER than the GLADIATOR!!!! If you like the Gladiator go look at both trucks!! Remember you will have to pay $12,650 MORE for the Gladiator (after lift, wheels and tires) than the GMC AT4!!!!! Now, buy the Gladiator! Congratulations!!!! Your an Idiot!!!!! You can do this with whatever brand you like! Chevy, Toyota, Ford, Nissan, it doesn't matter! When you buy the Gladiator remember to bring some lotion with you so it does not hurt as bad!! Jeep charges extra if you want them to use lotion!!

I need to see a Whipple coming soon, *do you?*

Test it against the Ram Rebel

I thought this was gonna be more powerful than the 3.5 high output. That woulda been amazeballs

At $69k you are in Raptor pricing territory. The redeeming feature over the Raptor is its payload/towing.

Just bought this with 43k on it the other day. It's a nice machine! 👍👍👊

Nice truck but for that money i could buy a 2500

That's what a real truck sounds like! 👍

This GMC costs a few grand more than Tundra & Titan because the Asian trucks are still 1/2 generation behind Ford, Ram, & now even GM with respect to the truck segment. The Ranger & Colorado have advanced features compared to Tacoma & Frontier as well. Resale value is also very close between GM & others in the truck segment.

close to $80 grand out the lot....cmon guys,really!

Best looking GM truck in the line up right now imo

Nice review!

The Silverado wished it looked this good

Just a word of caution - the new 2019 Silverado-Sierra twins can NOT even be ordered or does NOT come with the “power brake and foot pedal” adjuster.... Think about such a large truck without this option....If you have short legs, you have to move up the seat close to the steering wheel, which has an airbag in it. This is normally a pretty standard option for most trucks (GM, Ram, Ford)...I own a 2017 Silverado, but some “bean counter” within GM axed this very useful feature......why?

I would like to see a side by side comparison of the 3.0 L Duramax Vs the 6.2, mostly in towing and fuel economy.

It would be nice to know the real world MPG 5.3 vs 6.2

Exhaust sounds good

That exhaust was phenomenal. You should only buy a GM truck with the 6.2 and a car back exhaust🤤

Wow... Sounds like a vette, usually the 6.2 in these trucks sound more "trucky" (Idk how else to explain it lol). 👍👍💯

Great video, didn't like the "drama" song when he was about to go down the hill.

Do you know if any/all of those cameras will also work as a dashcam? Can you go back and review footage if there's an accident, hit a button somewhere to record the last x seconds, that kind of thing.

But overall, great looking truck. Hey Andre, love the ominous music during decent lol

Super nice truck great review! Andre my OCD is going crazy with your uneven pants leg!

I like it, but can't afford it.

Hope to see this in the Gold Winch Awards testing soon. :)

Any update on when you will get a 3.0l diesel 1st drive? I think initially one of you said last Oct. but we all know how that goes.

Ike Gauntlet boys, that's what that truck needs.

Just bought a 2021 GMC Sierra AT4 (6.2L) with all options available (except catback and air intake). MRSP was about $67,000. Not even close to what I paid. I have owned many trucks in my time...these 6.2L AT4's are a Corvette with 4-wheel drive. The seats have very little cushioning...not comfy at all. Cayenne Red Tintcoat

frig, gm makes hit so hard to choose between the trail boss and AT4

Thankful that they moved the gear shifter back where it should be for a truck.

The 6.2 is a whole different animal than the 5.3

nice review quick question, did you air down the tires for this video?

Still waiting for GM to come out with the 3.0l Duramax

The top of the line Tundra TRD PRO is $49,000. I’d rather get the Toyota because it’s a simple and reliable truck. In my opinion no truck should be over $50,000. You can buy a small home with the price of the Sierra.

I would totally buy this truck!

TFL can y’all please test the Sierra and the Chevy Silverado Trailboss?

You can get a Z71 (at least in 2018 you could) in a regular cab. Can you get this in a regular cab as well?

which one do you think is better the AT4 or Denali

That exhaust sounds really good.

let me get this straight, you get a cool new tailgate but because of all the new stuff there is also "nanny tech" in the tailgate that prevent you from using the bed extender that you need to use because the bed is only 5 ft long...... thanks but I will use the plan old tailgate on a useful size bed.

Do they make the 3/4 ton 2500 HD with the Duramax diesel? in an AT4? Especially would consider a 2020 HD AT4

Like the review but do you favor GM over Ford? Just asking because of titles and reviews!

Beautiful truck my next one for sure

I plan on getting the double cab 6.2 it's cheaper and also pit the borla s type on It instead

I wish ram,would do a off road ram performance package

Where in San Diego was this test area at ?

If they put the 6.2 v8 in the trailboss and the multipro tailgate then i am set with the silverado

It's my dream truck. I want it badly. However I HATE how the seats look in the AT4. I would LOVE to know if the leather seats could be swapped with SLT or Denali seats. I can't stand that brown mixed in with the black. I may be in the minority and it might not be a big deal to some, but if I'm paying that much for a truck, I want to LOVE the way it looks on the interior, and the seats are a deal breaker to me if they can't be swapped out. Other than that, I. Want. This. Truck. Looks wayyyy better than the SLT/Denali versions IMO.

What's the name of this trail and is it open to the public?

I’m really liking the AT4

Just because a fully decked out version lists for 70k doesn’t mean anyone is going to pay that. Knock 6-7k off the sticker - and more if you’re patient. Still too much but trucks are popular right now and the economy is good.

That's the best truck Chevy ever made 👍🏿

What no DSSV shocks not impressed at all maybe the GMC division should talk to the Chevy truck division about upgrading those shocks. I hope you guys at TFL get another chance to really test this truck.

GMC grandpa package 👴🏻 love the black plastic fenders👍🏻 keep up the cheap work GM.

One of my favorite truck

If only the wheel welds were circled then you can fit bigger tires like on the silverado

A Cadillac and Vette in a truck platform....wish I could afford it

Sounds good but I’m surprised they didn’t push to beat the F-150’s 450 horsepower EcoBoost V6.
