  • Massive bed capacity and a bounty of in-bed tie-down points
  • New touchscreen display is attractive and easy to use
  • Interior design and cabin controls look dated

  • Extra-large center stack takes up lots of cabin space
  • New 3.0-liter turbodiesel available as an option
  • 10-speed automatic now available with 5.3-liter V8
  • Optional bed-view and trailer cameras added to lineup
  • Adaptive cruise control now available
  • Part of the fourth Sierra 1500 generation introduced for 2019

The GMC Sierra 1500 is based on the Chevrolet Silverado 1500, and it shares almost all of its parts with that truck. The engines, the frame, the interior layout, and even most of the available options are identical. Yet the Sierra is more expensive. So why not just get the Silverado instead? Well, to justify its higher price, the Sierra 1500 offers a slightly more premium experience, a few higher-end materials, and some exclusive options that GMC hopes will draw you in.

One big party piece that the Sierra offers is the MultiPro rear tailgate. It's a six-position tailgate that can act as a table, an extension to the tailgate, or a large step for loading items into the bed. Another available option that gives the Sierra some cool factor is the carbon-fiber composite bed. Available as an option on the top trim levels, the CarbonPro bed promises decreased weight along with increased durability. Then there are the retractable side steps that can move forward and back for easier access to the cab or bed of the truck.

Aside from those GMC exclusives and some styling differences, the Sierra is the same under the hood. The GMC offers the same engine lineup as the Chevy, which includes a V6, a turbocharged four-cylinder and two V8s. And, just like the Chevy, the 2020 Sierra now offers a new 3.0-liter Duramax six-cylinder diesel engine. It provides robust towing capability, improved fuel economy and ample low-down torque.

All of these extras, coupled with a long list of standard features and impressive capabilities, make the 2020 GMC Sierra 1500 a tempting truck. However, rivals such as the Ram 1500 and Ford F-150 still hold an edge over the Sierra, with similarly equipped but less expensive trim levels and a more enjoyable daily-driving experience.

  • EdmundsEdmunds' Expert Rating
    7.3/10
    The GMC Sierra is comfortable and can be equipped with a rambunctious 6.2-liter V8. But getting the big V8 drives the truck's cost up, reducing its value. Still, if you're looking for the best interpretation of the GM family of trucks, the Sierra could be it.

Which Sierra 1500 does Edmunds recommend?

While you can go full luxe with the Denali, we think the best value comes from the midlevel SLT. It's standard with the likable 5.3-liter V8, or you can get the optional 3.0-liter diesel engine or the upgraded 6.2-liter V8 (our choice of engine). The SLT also has the trick MultiPro tailgate. Plus, most of the Denali's extra features, such as adaptive cruise control and the bed-view camera system, are available on the SLT as well.

GMC Sierra 1500 models

The 2020 GMC Sierra 1500 is available in six trim levels: base, SLE, Elevation, SLT, AT4 and Denali. The Sierra is offered in regular single cab, double cab and crew cab with a variety of bed lengths. All cab configurations are available with four-wheel drive.

The base Sierra comes with a 4.3-liter V6 (285 horsepower, 305 lb-ft of torque), a six-speed automatic transmission, air conditioning, a rearview camera, a tilt-only steering wheel, Bluetooth, a 7-inch touchscreen, Android Auto and Apple CarPlay integration, and a six-speaker sound system.

The SLE trim level adds a turbocharged 2.7-liter four-cylinder engine (310 hp, 348 lb-ft of torque) paired with an eight-speed automatic transmission, remote keyless entry and an upgraded 8-inch touchscreen. From the SLE on up, a 3.0-liter inline-six turbodiesel engine (277 hp, 420 lb-ft of torque) is available as an option as is a bed-camera system that adds a cargo-box camera and provisions for two additional trailer-mounted cameras. On top of the standard SLE gear, the Elevation adds a remote-locking tailgate, LED foglights, and two USB ports in the back seat.

Stepping up to the SLT, you add a 5.3-liter V8 (355 hp, 383 lb-ft of torque) paired with an eight-speed auto, a locking rear differential, a MultiPro configurable tailgate, dual-zone climate control, a tilt-and-telescoping steering wheel, a trailer brake controller, heated-and-ventilated front seats, and heated second-row seats. A 6.2-liter V8 (420 hp, 460 lb-ft) with a 10-speed automatic is optional.

GMC offers a Driver Alert 1 package for the SLE and higher trims. It includes driver assistance features such as parking sensors, blind-spot monitoring and rear cross-traffic alert. There's also the Driver Alert 2 package (SLT, AT4 and Denali only) that further adds forward collision warning with automatic emergency braking, adaptive cruise control and lane keeping assist.

GMC gives the AT4 trim similar features to the SLT but with a 2-inch suspension lift, standard four-wheel drive with a two-speed transfer case, skid plates, monotube shock absorbers, all-terrain tires, hill descent control, and a terrain-selectable traction control system.

At the top of the range is the Denali, which basically builds on the SLT's contents. It also adds exclusive adaptive suspension dampers, the Driver Alert 1 package and a seven-speaker Bose sound system. Many of the top-trim features are available as options on lower trim levels. Other options for the Denali include power assist steps, a head-up display and a rear camera mirror. Also available only on the AT4 and the Denali is a lightweight carbon-fiber composite bed.

    2020 GMC Sierra 1500 videos

    RYAN ZUMMALLEN: Modern trucks, are they luxurious? Yes, but are they fast? Also, yes. And today, we're going to find out which one is the fastest. For that, we've got a very special guest: the 2021 Ford F150 Hybrid. Yes, it is a hybrid. No, it is not officially called the hybrid. It is called Power Boost because that sounds cooler. It's also got a very impressive 430 horsepower, and 570 pound feet of torque. John is behind the wheel of that one, and I think he's feeling like all the pressure is on him right now. And I'm going to go ahead and agree because that will take all the pressure off of me. Speaking of me, I'm in the 2020 GMC Sierra Denali, and that's got a very extreme package on it called Carbon Bro-- sorry, carbon Pro. The Carbon Pro Package comes with a carbon composite bed that is lightweight and extra durable. That actually makes the Sierra, by far, the lightest truck that we have in this Drag Race today. If that wasn't enough, there's also a huge 6.2 liter V8 up front that is making 420 horsepower and 460 pound feet of torque. Finally, in the third trunk we've got Elana and she is piloting a 2021 RAM 1,500 now that has an engine that we're very familiar with a 5.7 liter vote, making 395 horsepower and 410 pounds of torque. Honestly, that's a lot of power, but it's kind of the underdog in this race today. But you never know what's going to happen, so let's see which truck is fastest. Before we get into the racing, don't forget to hit that Subscribe button like my job depends on it, so you don't miss any of our videos. And there's a edmands.com for all your car shopping needs. On top of that, if you go to edmands.com, you can get a cash offer on your car right now. OK, guys, for this first run, let's go two wheel drive and see how it goes. ELANA SCHERR: You're the boss. RYAN ZUMMALLEN: They don't know this, but I'm also going no traction control to try and get a better start. So we'll see how that goes. SPEAKER 1: Let me know when everyone's ready, and I'll do the countdown. ELANA SCHERR: Are we leaving on one or after one? SPEAKER 1: It will be a 3, 2, 1, go. On go. JOHN ADOLPH: So on the G go or the O of go? ELANA SCHERR: Be quiet. SPEAKER 1: 3, 2, 1, go. RYAN ZUMMALLEN: Get it, get it. I think I got Elana. Oh, no. John's catching up. Oh, no, he's going to take it. JOHN ADOLPH: Boom. RYAN ZUMMALLEN: Oh, I really thought I had him. ELANA SCHERR: You sleepy mofos got saved by horsepower. JOHN ADOLPH: Well, you both definitely got the jump on me by a lot. RYAN ZUMMALLEN: Yeah, I think with another practice, you will get a much better jump and then we really won't have a chance. But I did think I had you for a good couple of seconds, and then that was that. ELANA SCHERR: I am going to be reduced to crashing into you if I want to win this. RYAN ZUMMALLEN: I don't know about you guys, but I thought that was a pretty impressive run by all three trucks. ELANA SCHERR: I would not say that I was impressed by the Rams performance there, no. RYAN ZUMMALLEN: You jumped out so fast, though. ELANA SCHERR: That wasn't the truck, friend. No, the RAM is a great truck. 10 years ago when 400 horsepower was full on bragging rights, this thing would have blown everybody's minds. But nowadays, I mean, heck, FCA puts a Hellcat in a Ram truck. Now so I'm just not satisfied with the five seven. RYAN ZUMMALLEN: John, surprised? JOHN ADOLPH: It was really smooth. I mean, I don't know. I'd want to go back to back to back to see the difference. ELANA SCHERR: You just want to win repeatedly. JOHN ADOLPH: I must admit, it feels good. ELANA SCHERR: Do you want to try it in four wheel drive? I mean, maybe my problem was just that I wasn't putting all the power down. RYAN ZUMMALLEN: Yeah, that was my problem too, definitely. So let's remedy that and put John where he belongs. ELANA SCHERR: I think the big problem with that plan, Ryan, is that John also has four wheel drive. All right, John, Ryan, you guys are putting it in four wheel drive high. It's pretty simple here. I just press a button. JOHN ADOLPH: I already put it in sport mode, which automatically sets it up four. High four automatic. RYAN ZUMMALLEN: I'm in four high and I just discovered I have a sport mode, so you guys are in trouble now. ELANA SCHERR: Well then, I guess we should do this thing. SPEAKER 1: OK. 3, 2, 1, go. RYAN ZUMMALLEN: Sport mode, don't fail me now. Oh, better, better, better. Might have it this time. Oh, that was so close. I honestly don't know. He got me at the very end, but I think I might have crossed the line first. John, do you know who won? JOHN ADOLPH: I think it was you, Ryan. I was creeping up, but I couldn't catch you. I don't know if being in four made a difference, or I was just sleeping at the light. ELANA SCHERR: You were so sleepy, I could hear your dreams. I mean, no one can say I'm not trying. RYAN ZUMMALLEN: No, but you're not winning either. ELANA SCHERR: Ouch. I mean, I think it's nice of you, John, to at least give us a moment of thinking that we might have a chance at winning. JOHN ADOLPH: You guys want to do best two out of three? ELANA SCHERR: Either that or a role race. RYAN ZUMMALLEN: So for the third and final race, we're going to do a rolling race. From 40 miles an hour, we'll all be traveling together, and then we'll all smash it and see who can win from there. So that is going to be more of a real world replication, like if you're merging onto a highway or you're traveling down a straight road, and need to pass a slow Prius in front of you. Rolling race. Here we go. Let's see, homes. Mash it. JOHN ADOLPH: Come on, come on, come on, come on, come on, come on. RYAN ZUMMALLEN: Sport mode. Come on, carbon fiber. Come on, 6.2. Nope, not happening. JOHN ADOLPH: Oh, I love it. F150 wins this time. Congratulations, John. ELANA SCHERR: I just want you guys to know that I have a lot of snacks in the giant console in the room and I am not sharing them. JOHN ADOLPH: I have to admit, it's fun to win. But it's bittersweet because there's no skill involved, whatsoever. I can't be really that proud, it's just mash it and keep it straight. ELANA SCHERR: I mean, what better reason to buy a fast truck than to just be like, even the skill-less can win races. RYAN ZUMMALLEN: Just imagine if you had a carbon fiber bed. As fun and dramatic as that was, our real world race isn't really that surprising. Here's why: the results were pretty predictable based on our own independent instrumental track testing. That showed the F 150 blasting to 60 miles an hour in just 5.7 seconds, despite being the heaviest of the bunch. With the Sierra in hot pursuit at six seconds flat, and the Ram finishing in style at 7.3 seconds. In the quarter mile, this year, I had reason for hope given our observed time just 2/10 of a second behind the Ford, at a speed just a hair faster to boot. Again, the Ram, well, at least it looked good. When it comes to braking, again, the Ford and GMC are neck and neck, with the F 150 besting the group at 129 feet to a complete stop. While the Sierra needed 130 and the Ram took 138. Finally, on the skid pad, the Sierra took top honors measuring 0.79 lateral g over the F150's 0.78, and the Rams 0.72, which, of course, is critically important when you're all crossing your work truck. If anything, this test drove home the pure beastly power of the GMC's 6.2 liter V8. But even more than that, it showed the astonishing ability of the F 150s hybrid system to counteract all this additional weight. OK, three races down. I caught him once, so that's one for the Sierra. But the other two went pretty decisively to the F 150. That is a seriously fast truck. All three of these trucks are impressive. This one is impressive because of old school brute force. The RAM is impressive because it's just comfort everywhere you look. And the Ford is impressive because that thing feels like the future. And I wouldn't be surprised if a few years from now, we're having a three way hybrid race between these three brands. Who knows? But until then, F 150 wins into Drag Race, and it was fun finding that out. Thanks for watching. Don't forget to like and subscribe so we can keep making more videos like this.

    GMC Sierra 1500 vs. Ram 1500

    If you're looking for a luxury experience in a full-size truck, the Sierra and the Ram are two of the top choices. The Ram, however, offers a better cabin, more comfortable seats and a better highway ride than the Sierra. The Sierra has more powertrains to choose from, but the Ram counters with three impressive engines of its own. Read Edmunds' long-term road test of the Ram 1500.

    GMC Sierra 1500 vs. Ford F-150

    Available with a dizzying array of options and a seemingly endless combination of engines and cab configurations, the Ford F-150 is a seriously versatile truck. It also has some top-notch towing and hauling numbers if you're looking for a capable work truck. Like the Ram, the Ford F-150 will appeal to more price-conscious buyers than the Sierra 1500.

    If you're looking for all the GMC Sierra's capability but don't want to pay the luxury premium, the choice at this point should be clear: the Chevrolet Silverado. There's very little mechanically that separates these two trucks. And if you like them both, it might just come down to a styling preference.

    2020 GMC Sierra 1500 First Impressions

    What is it?

    Like its Chevrolet Silverado 1500 stablemate, the 2020 GMC Sierra 1500 is a full-size pickup truck that is available in crew-cab, double-cab and regular-cab configurations. No surprises there. For 2020, there are some new trim options and, most notably, a new powerplant. Along with the previously available gas engines, the Sierra 1500 now offers an optional turbocharged diesel six-cylinder engine.

    This engine differs from other half-ton diesel pickup engines because it's an inline-six instead of the usual V6. Since it's longer, it takes up more engine compartment space. But engines with this layout tend to run smoother and produce more torque. The Duramax's power ratings support this: 277 horsepower and 460 lb-ft of torque. GMC pairs this engine to a 10-speed automatic transmission.

    2020 GMC Sierra 1500 - Front
    2020 GMC Sierra 1500
    Why does it matter?

    Every 2500 and 3500 HD pickup truck has a diesel engine option, and they're always in demand despite the extra upfront cost. The same has not been true of the 1500 series "half-ton" segment. For years there wasn't a single choice until Ram reintroduced a diesel in 2014.

    Diesel engines are popular among truck buyers because they excel in two key areas: They make abundant torque for easier towing and offer better overall range and fuel economy. They are especially good at doing both at once by providing respectable fuel economy and range while towing.

    2020 GMC Sierra 1500 - Rear 3/4
    2020 GMC Sierra 1500
    What does it compete with?

    Ford sells a 3.0-liter Power Stroke turbodiesel V6 engine that makes 250 hp and 440 lb-ft of torque. Fuel economy in combined city/highway driving is rated at 25 mpg for two-wheel-drive models and down to about 22 mpg for four-wheel-drive versions. Towing is pegged at a maximum of 11,400 pounds.

    Ram began selling a 3.0-liter EcoDiesel in 2014, and sales were brisk until it was pulled from the lineup due to problems with emissions certification. It's finally back in the 2020 Ram 1500 and offers strong competition with ratings of 260 hp and 480 lb-ft of torque. It's also rated to tow as much as 12,560 pounds.

    The Sierra, with the new diesel engine, can tow up to 9,100 pounds. Is this a huge problem for GMC? In terms of bragging rights, absolutely. But 9,100 pounds is still plenty of capacity. And if you really want maximum towing, you can get the gasoline V8 for up to 12,100 pounds. The Duramax engine exists to provide superior everyday fuel economy. The EPA estimates it'll get 24-26 mpg in combined driving, depending on configuration.

    2020 GMC Sierra 1500 - Detail
    2020 GMC Sierra 1500
    How does it drive?

    The days of trading ride comfort and handling for the hauling and towing power of a pickup are gone. The Sierra 1500 is so smooth and quiet that we had to pull over after a mile into our evaluation to check the badge and make sure we were driving a Sierra with the Duramax engine. The diesel and 10-speed automatic provide smooth and seamless power in all situations. There is no wind noise, little engine noise and minimal tire noise — even in the lifted AT4 trim level.

    Visibility in the 1500 is good, although it lacks the giant square windows of its big heavy-duty siblings. It's still easy to see out of. It's also surprisingly nimble and stable. We've been in Cadillacs that had a more punishing ride quality.

    Don't think that just because the Sierra is quiet and plush, that it isn't capable. The AT4 trim equips the Sierra with a 2-inch suspension lift and optional all-terrain Goodyear Wrangler DuraTrac tires. It will happily ramble over rocks or through the mud, so you know it won't have any trouble hauling a couple of dirt bikes down a dirt road to wherever you plan to do your On Any Sunday remake.

    What's the interior like?

    We've given Chevy a hard time about the Silverado's less than thrilling interior. GMC steps it up, but not enough. While the materials are soft-touch, and there are a few pops of color and texture, the Sierra just doesn't push the interior design, even in the high-level Denali. It's monolithic and monochromatic, like driving the artifact from 2001: A Space Odyssey — shiny, vertical and black.

    Ford and Ram are doing more in this space when it comes to visual appeal. However, the Sierra's seats are comfortable and available with heating and ventilation. The controls are easy to understand and easy to get to, which isn't always the case in a big-truck interior. The center console could fit a watermelon, and the back seats are large enough for your largest friends.

    How practical is it?

    If you ever fret about towing, GMC's ProGrade trailering system will cure your ulcers and may inspire you to take the boat out more. A combination of cameras, optional tow mirrors, parking brake assist (for easier hitching), and an integrated trailer brake controller make dangling a trailer as easy as driving without one.

    You can bring up a combination of 15 different camera angles on the center touchscreen to keep an eye on every corner of your payload. And if you get the optional head-up display, you can keep those towing camera displays up while using the head-up display for other info, such as navigation directions. There's even an option for a camera that shows you the inside of your trailer. It takes all the guesswork out of changing lanes and turning corners, and it will make even experienced haulers breathe a sigh of relief.

    Speaking of hauling, the Sierra has some nifty bed features, too. First is the previously available MultiPro tailgate, which you can lower as either a traditional one-piece or separate to create a handy step or a tailgate party hangout. Our only criticism is that having a hitch installed can interfere with deployment of the MultiPro tailgate's step position. Want some tunes? Add a built-in Kicker audio system to the bed, which GMC says uses the same technology as watercraft stereos, so you don't have to worry about shorting it out if you're partying in the rain or launching a speedboat.

    If you opt for the Sierra's CarbonPro bed, you get to be an early adopter of some very cool technology. Ford may have aluminum, but GMC is going carbon fiber. The molded bed is a mix of cut carbon and resin, and GMC says it is more abrasion- and impact-resistant than any of its competitors.

    What else should I know?

    The 2020 Sierra 1500 is a well-designed truck with several unique options. The Denali and AT4 are high-level choices, but the new Elevation edition is an attractive vehicle at a lower price point. GMC doesn't have the bragging rights on numbers for its 1500, but it has an edge on technology and refinement.

    EdmundsEdmunds says

    For 2020, the GMC Sierra 1500 gets some pretty big improvements in the powertrain and technology departments. There's a new six-cylinder diesel engine added to the lineup, and the available 5.3-liter V8 can now be paired with GM's 10-speed automatic transmission. You can also get GMC's new bed-camera system, which includes the capability to attach two more cameras on your trailer. Combine these improvements with Sierra's stout capabilities and you've got a much more appealing truck.

    Should I lease or buy a 2020 GMC Sierra 1500?

    Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
