2020 GMC Sierra 2500/3500 Walk-Around: Video



By Aaron Bragman

All the redesigned heavy-duty pickup trucks are destined for U.S. showrooms this year, and we've had a good look at two of the latest — the 2020 GMC Sierra 2500 and 3500. Just like the 2020 Chevrolet Silverado 2500 and 3500 trucks, the redesigned GMCs sit on a new frame, feature all-new styling, new interiors, new powertrains and increased capability.

You can choose from two powertrains: a brand-new 6.6-liter gasoline V-8 or a turbo-diesel 6.6-liter Duramax V-8 with an unchanged 445 horsepower and 910 pounds-feet of torque. The gas engine rated at 401 hp and 464 pounds-feet of torque gets a six-speed automatic transmission, while the diesel gets a new 10-speed Allison automatic. The AT4's four-wheel-drive system now has an automatic mode, with selectable terrain adjustments for different terrains. The 3500 is rated to tow up to 35,500 pounds, according to GMC, a big bump from the outgoing truck's maximum numbers. And out back, there's the same MultiPro Tailgate you can get on the light-duty Sierra.

Inside, it doesn't look any different from the Silverado HD trucks — or even all that different from the light-duty 2019 GMC Sierra 1500. The big news is the replacement of the All Terrain trim with the new-for-2020 AT4 off-road version. Like the Sierra 1500 AT4, the HD version gets a host of unique visual upgrades to the grille, trim and interior, but it also gets mechanical upgrades like an off-road suspension with Rancho shocks, extra skid plates, a locking rear differential, Off-Road mode for the Traction Select System, hill descent control, hill start assist, a head-up display with an off-road inclinometer and surround-vision cameras.

The Florida panhandle. About as far south as you can go and still have 4 seasons.

They've got a DoubleTree and a Best Western too

Some say the Emerald Coast of the panhandle has the most beautiful beaches in the world.

Unless you count Siesta Key on Sarasota beach. Or go south about twenty five miles and there's Englewood.

I almost grew up in the Panhandle beaches but they are too crowded today and presently we're a week or two away from the madness of Spring Break.

Much of the beach at Panama City is still not rebuilt from the hurricane last fall. Go to Sarasota instead.

I almost grew up in the Panhandle beaches

Does that mean near or spent a lot of time there?

We lived there in a van down by the beaches.

Walton County. Bay County.

Papa lives in a RV? That's ok You're a good man, you just hit a bad streak. You'll get back.

papajim doesn't live in a RV. He lives in a shipping container.

looks like JTT (and Frank and rest of the nut squad) skipped church this morning


Actually the ford F-series is the best selling vehicle in the world. And no one in the world sells more trucks than Ford.

The F-series is not a single model vehicle, therefore you can not claim it to be the best selling vehicle.

Adding to this, the WORLD is not USA. Since the F-series is a combination of models it is not the best selling model in the WORLD. Even being generous... of say 67% of the F-series being F150 model, there are still 6(SIX) other vehicle that out sell the F150 in the WORLD... I'll save you the head scratching...

(67% F-series as F150) - 721,023

Corolla - 934,348
Civic - 812,767
Rav4 - 807,116
Rogue - 771,145
CR-V - 736,471
Golf - 731,561

And yes, I know you said trucks. Just putting your world into perspective.

Shockingly... they are all non-USA manufactures. Wow, the world is big isn't it. lol

We can even go one step further, the WORLD is really made from China.. A very large portion of everything we see, own and use on a daily basis is made from China... to put it lightly, the world IS made from China.

REPEAT: Where did you get your facts?

Past and current event are my facts.

Educate yourself to the facts of the death and hate cult mind polluting ideology called islam

There is a place in Alaska, where you can escape just far away enough to never have to worry about people coming after you, it is called 'Twin Lakes', check out the video 'Alone in the Wilderness'. If you don't want to go that extreme, you could always just try putting a foil cap on your head, with the bonus that it might protect you from an electromagnetic pulse weapon as well.

@ Texas1836

Dhimmi, you need to educate yourself on islam as well

Oh my, more videos from the Chicago show? Yawn...

I may know a little more than you are giving me credit for. You have no idea who I am, and I have no idea who you are. I choose not to disparage other people's religion on this pickuptrucks.com website, or on any other website for that matter. Once again, you should not be posting that kind of stuff here. You should look up US crime statistics for the group you are putting down, they commit less crimes, and are better educated on average than their typical US counterpart. I suspect your IP address will be blocked anyway with the changing of the guard here at PUTC, as they are clearly cracking down...you may have noticed that many of your recent disparaging have already been removed.

Not me I didn't say papajim lives in an RV. I might not like the guy but I am not going to go low, there is enough of that in the comments section. I don't really care where papa lives or what he drives.

It also doesn’t mean Ford should have used pushrods on the Coyote, and it doesn’t mean the GM 5.3 is bette than the Ford 5.0. Ford’s 6.2 is also a really good motor. I’m not knocking GM motors either, I’m just saying they both have advantages. If the 7.3 will be used for electrification at some point, then pushrod really does make sense. There seems to be little benefit of high rpm power on medium duty trucks.

The 5.0 is more inline with the 6.2 based on power output and fuel efficiency. Displacement vs output vs efficiency gets complicated when it comes to comparing a 16-valve pushrod V8 to a 32-valve DOHC V8.

The 7.3 is not going to be used for electrification anytime soon. There's little reason to electrify an engine that's primarily meant for trucks that are not as strictly regulated for fuel efficiency and emissions.

The interesting comment you made, "There seems to be little benefit of high rpm power on medium duty trucks", can be applied to light duty trucks as well. Which makes it all the more baffling that Ford decided to shove OHC V8's down our throat to begin with. They mothballed years of great truck engines simply because those engines were "old-school" pushrod engines. Why did we need OHC to begin wit? All it does is increase the odds of a problem with the valve train and meant that a smaller displacement V8 burns as much fuel as a larger displacement V8. Ford made a mistake by throwing away all their pushrod engines. Now they suddenly realize they probably should have kept some of those engines because trucks don't need complicated engines that rev up over 6,000 rpm.

You reach the same conclusion that GM execs and engineers came to during the 1990s after years of experience trying to build Northstar 32 valve V8 engines. The 4.6 Northstars were very popular with owners of Cadillac sedans because they seemed to make a lot of power for their size. They were expensive to make and maintain.

As a result, GM chose to build a new generation of pushrod V8s and as they say, the rest is history. At everyday engine speeds of 2,000 to 4,000 RPMs the pushrod engines really perform, and they suffer no loss whatever to the similar displacement OHC engines.

With a lot fewer moving parts and much simpler manufacturing.

I own a 10 year old truck and I can swear to you that the 4.8 Gen 4 engine is my favorite of the bunch because of what it DOES NOT have---no VVT and no variable-displacement.

Pure smooth and simple performance. Barring something unforseen I can imagine it going to 200k miles with no problems.
