2020 GMC Sierra Duramax

2020 GMC Sierra Duramax welcome to our website carsauthority.com a website that discusses various types of car models that are popular in the world, we really expect our website to be your choice in speaking automotive world, I hope you enjoy our review. In the high-stakes globe of half-ton pickup, obtaining your purchasers the appropriate mix of style and also modern technology is critical. Insufficient, and also you can taste boring; excessive, as well as you run the risk of indigestion. 

The technique, it seems, for smartest pickup manufacturers is to provide various features and tastes for a wide range of consumers so they can find what they like. And that seems to be exactly what GMC is trying to do with its 2020 Sierra 1500 (all new in 2014), which now supplies an all brand-new, all-aluminum 3.0-liter turbodiesel I-6 engine, ranked at 277 horsepower at 3,750 RPM and also 460 lb-ft of torque at 1,500 RPM. Both Ford, as well as Ram, have recently introduced/re-introduced their light-duty diesel into the segment; nevertheless, this new GM straight-six appears to be one of the most solid choices of the number.

2020 GMC Sierra Duramax


We've currently read about GM's all brand-new light-duty diesel in our Initial Drive piece on the 2020 Chevrolet Silverado 1500 Duramax, and simply in situation you really did not recognize, the GMC Sierra 1500 shares this brand-new engine with the Chevy Silverado 1500. In our earlier drive, we suched as the engine as well as its performance feel, but we didn't get to do much carrying, lugging, or off-roading. This time around, with the 2020 GMC Sierra Duramax, we got to do all three.

To offer a fast technological recap, the new light-duty diesel uses an all brand-new I-6 layout for tranquility as well as balance, using an aluminum block as well as head configuration with a variable consumption manifold and also modern high-pressure fuel injection. Furthermore, the engine can send out trendy or warm liquids to the block as well as head as needed, and has a variable geometry water-cooled turbocharger as well as stop/start technology-- all mated to the new 10-speed transmission. 

The entire point creates 95 percent of peak torque in between 1,250 rpm as well as 3,000 rpm. A level torque curve like this means more drawing power for longer periods of time, always a good thing if you take place to be using your pick-up like a pick-up.

How does it feel on the road? In 2 words, smooth as well as receptive. Naturally, we're presuming a great deal of that has to do with the computer software combined with the new 10-speed transmission (also newly readily available for 2020 with the DFM 5.3-liter V-8), which never ever provided us any severe shifts or hunts during our drive paths.

We played a fair bit with the selectable dial settings, too, and found everyone (Sporting activity, Touring, Off Roadway, and also Tow/Haul) to provide an one-of-a-kind feeling, altering shift factors, grip control settings, throttle feedback, and a lot more. We wound up choosing the more controlled feeling of the AT4 suspension over the comfy and also floaty feeling of the Denali, however you can always transform the personality of this truck with the different trans pick selection. Regardless of what you like, there's a great amount of adjustability.

And also for those who tow (especially in or near the hills), this new engine utilizes its turbocharger to supply a healthy dosage of backpressure (as an automatic exhaust brake) to control downhill rates. Although none of the light-duty diesel engines in this sector provide for a separate exhaust brake switch (as is standard on the bigger HD turbodiesel), the 3.0-liter Duramax is the just one that totally integrate this feature in its Tow/Haul arrangement. 

We really felt the difference when lugging an 8,000-pound box trailer down a 6-percent grade. Our car held its equipment, keeping a continuous engine rpm to give us a great quantity of control in traffic, enabling us to function our brakes moderately.

Although we haven't had the opportunity to do any kind of track screening with this powertrain (keep tuned for our upcoming Vehicle of the Year competitors in the following couple of months), we discovered the acceleration feel to be outstanding. Throughout our latest examination drive in the Rocky Mountains near Jackson Opening, Wyoming (at 6,300 feet over water level), we had both a new Denali and also AT4 crew taxi 4x4 with the new Duramax. Even here, we found the throttle feedback to be crisp and also precise, yet when in Sporting activity setting, the hulking pickup actually felt active and fast off the line and also rather comfortable diving in and also out of difficult corners. 

The GM designers handy informed us the whole lineup of half-tons had their suspensions (both front coils and also leaf rear springs) retuned for the 2020 version year, mostly because of customer feedback. One of the most excellent modifications we experienced was on the preferred AT4 bundle, where we noticed the Rancho monotube shocks doing a far better work handling higher-speed inputs. The high-speed desert laundry group will certainly be much better with this retune.

For those that might not recognize with the relatively new AT4 off-road plan (an evolution of the earlier All Terrain bundle), it supplies several one-of-a-kind functions that make it a strong entertainer in tough surface. When paired with the torquey efficiency of the Duramax engine, we're presuming this will likely be just one of the most popular setups for those that like to discover remote from the northeast to the southwest. 

For full disclosure, 2020 GMC Sierra Duramax AT4 bundle is efficiently the like the Chevy Silverado 1500 Path Manager, providing an uniquely tuned 2-inch suspension lift, Rancho monotube shocks, larger wheels and also 32-inch all-terrain tires, extra skid-plating, a G80 auto-locking back diff, and also a few various other innovation details like border view cams, hillside descent control, and a shade heads-up screen that supplies ahead, back, as well as side-to-side slope readouts.

We had the opportunity to run a Duramax AT4 over a nasty rock-strewn course in reduced variety and also located the arrangement, specifically with the forward and surround-view video cameras, an easy no-spotter, hassle-free climb. Likewise readily available is an attribute that discovers the pitch of your incline when you take your foot on-then-off the brake and also will certainly hold it immediately until you touch the throttle. 

That hill-hold modern technology could protect against a lot of body damages in places like San Francisco and also Seattle, also. Throughout this section of our examination, we rapidly figured out cams are just comparable to their capability to shed mud and dirty water. It would certainly have been nice to have a fast squirter nozzle (a minimum of on the front and also back lenses) to provide us a suggestion of what to anticipate when we unlock.

Plainly, the off-road part of our test was the most fun, but empty and also crammed runs through the mountain roads linking the part of Wyoming and also Idaho along the Serpent River offered us a chance to allow the equines run. We obtained a pretty good suggestion that this configuration is more than efficient in multi-tasking, a particularly important information for many new-truck purchasers. 

Regarding just how this bundle (Denali or AT4 Duramax) will certainly stand up versus the Ram and Ford offerings, we can not be exactly certain, offered our altitude driving and restricted time with the trucks. But we can say GM engineers have actually done a stellar task effortlessly incorporating the engine's power with the super-smart, selectable 10-speed transmission. We never really felt a hard shift or clumsy quest for the next equipment whatever the circumstance, which we have actually experienced in both of its competitors.

2020 GMC Sierra Duramax

2020 GMC Sierra Duramax

Given that we're discussing how this brand-new light-duty pickup compares with the competitors, we simply have to keep in mind there are still fairly couple of (if any) changes to the interior of the different trim degrees for the 2020 model year, Duramax or otherwise. So if you were wishing for GMC to up its game (also ahead of Chevy) for this new powertrain setup, you'll have to wait a little longer. Both state-of-the-art Ram and also Ford light-duties (as well as even a few of their midlevel trims) appear to be doing a better job with product choices, format, and also layout. 

That stated we're willing to provide both Chevy as well as 2020 GMC Sierra Duramax a little more time. Still, GMC is doing well with unique modern technologies like the creative Multi-Pro Tailgate and also virtually unbreakable Carbon Pro composite bed, however, you can expect more attention-getting attributes ahead.

2020 Duramax Sierra 1500s should be getting to car dealerships currently and also will be priced identically to the 6.2-liter gas V-8 engine, or a $2,495 option over the 5.3-liter DFM gas V-8, as well as a $3,890 costs over the criterion (in some cases) 2.7-liter turbo I-4. The Duramax will eventually be readily available across the schedule in all arrangements, with the exception of the entry-level Sierra trim bundle in the meantime.

2020 GMC Sierra Denali 3500

2020 GMC Sierra Denali 3500 The General Motors pickup approach is rather simple; attack the market with two brands where rivals only offer a solitary option. As it relates to sturdy customers, we have actually already seen what they have actually done with the all-new platform, controversial styling, and outstanding hauling modern technology in the 2020 Silverado 2500 and also 3500, as well as currently it's time for the GMC side of the family to roll out their HDs and distinct features.

The 2020 GMC Sierra Denali 3500 and 3500 models are started on a totally new, stronger, longer, as well as taller ladder framework, specially created to provide bigger max towing as well as payload numbers. Throughout every configuration, specific factors to consider to thicker, lighter, and also advanced materials have been consisted of in the structure, upgraded suspension elements, as well as even in the powertrains themselves, causing higher optimum haul (in excess of 7,000 pounds) and also optimum towing numbers (in excess of 35,000 extra pounds). Right here's an enjoyable truth GM engineers want you to recognize: every configuration of GM's one-ton dually (whatever taxi, what engine, what drivetrain) can tow greater than 30,000 pounds. Neither Ford nor Ram can state the exact same.


A huge piece in this HD challenge is, as you may think of, under the hood. Although the 6.6-liter Duramax turbodiesel (ranked at 445 horsepower at 2,800 rpm and also 910 lb-ft of torque at 1,600 rpm) is generally a carryover engine selection, it is currently mated with an all-new Allison 10-speed transmission, which sporting activities a larger, much faster computer system controller. 

In addition, there's a brand new gas engine selection in the type of a 6.6-liter direct-injection V-8, rated at 401 horsepower at 5,200 rpm and also 464 lb-ft at 4,000 rpm. This brand-new engine replaces the long-past-due 6.0-liter with a hill of tried and tested and also brand-new technology and compares incredibly well with the new Ford and also Ram gas V-8 offerings.

From an outside style point of view, GMC internals proceeds their push to separate themselves from their Chevrolet brethren. For much better or even worse, 2020 GMC Sierra Denali 3500 has taken a more traditional method, maintaining their multi-block grille, front bumper, as well as front lights layouts much more in keeping with the half-ton models. 

The most significant modifications to the Sierra HD front ends remain in real size, driven in large component by the included air movement requirements needed for both the diesel and gas engine choices. The front end still provides dual-intake opportunities for cool air (one incorporated in the hood, the various other through the broader grille), today additionally adds a significant under-bumper mini-grille to route air either to the intercooler (for the diesel) or transmission cooler (for the gas).

Home window beltlines have been lowered for the better vehicle driver as well as guest presence as well as the real bed sill elevation is reduced also. We especially like that all HDs will certainly provide incorporated avoids into the rear bumper and also bed body (one in front of the back wheel well, one in the bumper edge) on all models for easier, quicker accessibility to anything in the bed.

We just recently had the opportunity to do a fair bit of highway towing, off-roading, and also haul traveling around Jackson Opening, Wyoming (around 6,000 feet over water level), with several new Sierra HD models as well as, briefly, right here's what we found:

Freeway Towing: The Duramax/Allison is an outright monster when drawing heavy lots. Unlike some max-tow powertrains, the 6.6-liter turbodiesel provides 100-percent of its torque off the line and also the new 10-speed transmission does an outstanding work of efficiently as well as consider getting all that power to the rear wheels. Our initial 3500 dually staff taxi 4x4 Denali (detailing simply under $82,000) was towing a Keystone Montana fifth-wheel Recreational Vehicle with dual slide-outs, considering in around 13,000 pounds completely dry. 

With the exhaust brake on as well as in Tow/Haul (which gave us some instead aggressive grade-braking downshifts each time we tapped the brake), our time with the truck as well as the trailer was rather comfortable and also trouble-free. Include in this a myriad of trailering camera options (front, both side mirrors, bed, tailgate, and a final hard-wired electronic camera on the back of the Motor Home), and we can see practically whatever or anybody intending to sneak upon us. We should keep in mind that GM is the only HD truck maker that offers an incorporated Transparent Trailer function that (when set up properly) enables the chauffeur to translucent the trailer you are lugging to those chauffeurs following you (much of whom may wish to pass). 

This technology is not only great, but it also supplies an added level of security as well as the situational understanding we have actually never experienced. In addition, we pulled with a gooseneck flat-bed that supposedly considered over 25,000 pounds with a one-ton dually as well as located the workings of the drivetrain plenty strong enough to pull the load confidently, feeling fairly composed the whole time. Of course, we'll have to book our last judgments for long-haul towing (and also any overheating concerns) until we can get an examination truck and also set up a multi-state run.

Off-Roading: One of the most significant sales shocks recently for GMC is their latest off-road bundle, called the AT4 (in fact a developed trim from earlier All Surface packages). Used on both light-duty and also sturdy platforms, the AT4 bundle for the HD supplies bigger wheels as well as tires, specially tuned Rancho monotube shocks, additional skid-plating below, a Traction Select system with an one-of-a-kind Off-Road setting, Hill Descent and also hillside hold attributes, a 15-inch shade head-up display screen with an off-road inclinometer, and a high-def surround-view electronic camera. 

The 2500 or 3500 AT4 is special to the GMC brand name (significance there is no Chevy Silverado HD Route Boss at this time) and, with the exemption of an anti-roll bar detach and also winch, this might be the closest thing to a Ram 2500 Power Wagon competitor. We had the chance to penalize a couple of AT4s on both some higher-speed, rough dust roads, along with some rocks as well as awful 4x4 trails we located near Grand Teton National Park. Distinctly, the transfer instance provides both all-wheel-drive, 4x4 high range, and also 4x4 low array modes, each with a different Off Roadway mode setting in the transmission to assist boost traction control and throttle feedback. 

We found this hugely helpful when browsing a deep river clean that at some point got rocky after that turned back into tire-swallowing, fluffy, smooth sand. Returning and also forth between the 4WD settings is all push-button, needing us to be in Neutral just when relocating right into or out of 4 Low. To state the obvious; this was the most enjoyable we had in a 2020 GMC Sierra Denali 3500 pick-up the whole week. And, we should likewise keep in mind, the AT4 bundle ensures no down-rating in a max haul or towing when contrasted to various other non-AT4 HDs (something the Power Wagon can not claim).

Haul Cruising: We likewise had the possibility to run rather long stretches of hill highways with both a Sierra Denali 2500 and also Sierra AT4 2500 with at or simply above 2,000 extra pounds of fresh reduced visit the bed (all effectively stripped down). Of particular note, which is a pet dog peeve of ours, we loved the reality that despite that much weight in the back there was really little rear-end droop from the back springtimes. Neither of our test trucks revealed any type of difficulty accommodating the weight or compromising any flight or managing high quality as we carved through the canyons parallel with the Serpent River.

We need to keep in mind, however, our AT4 filled with logs did have the brand-new V-8 gas engine, which did appear to have a little bit extra difficulty keeping up with traffic as we crossed over a mountain pass, and, with 4 less equipment than the Allison (but reduced 3.73:1 axle equipment-- all Duramax HDs obtain 3.42:1 equipments), it did still seem to struggle a bit a lot more. With all that said, we were still fairly amazed at just how well both the Denali and also AT4 suspensions managed the lots, giving a well balanced as well as made up chassis throughout hill road cornering.

However what concerning the interiors? If you were trying to find something remarkable or a substantial upgrade in the 2020 GMC HD insides, you will not be happy. Essentially, every little thing we've already seen from GMC (mainly from the brand-new insides of the light-duty trims) will be carried over into the HD lineup. Anticipate the top-of-the-line Denali to still disappoint the what Ram and also Ford are making with their leading trims-- meaning you'll still see the typical chrome surrounds with brushed lightweight aluminum accents and plasticky wood trim items on the center console as well as door panels. 

We really such as the concept of keeping the interior appearances between light-duty and durable comparable yet we 'd actually like to see more dramatization with better-quality materials as well as choices. Past that, the softer dashboard materials and also sewing choices are still respectable, just not for a vehicle that can easily run above the $75,000 mark. We consider this the most significant location of opportunity for 2020 GMC Sierra Denali 3500 and also, unlike a few of our associates, we want to wait and see what's most likely to come in the following mid-model refresh.

The rollout for the brand-new GMC Sierra 2500 as well as 3500 versions is happening currently, however, the more preferred versions (definition team taxicab 4x4s) will certainly precede, after that the others later on. Expect the AT4 as well as Denali crew taxis first, with various other trims and taxicabs rolling out after that. Ultimately, 2020 GMC HDs will certainly provide 3 taxi setups, 2-bed sizes, two engine choices, and five trims-- the value-oriented Sierra trim, the extra mainstream SLE and also SLT, then provide the even more well-equipped AT4 and also Denali for those intending to fully alternative and have more style. 


2020 GMC Sierra Denali 3500

Entry-level Sierra HD regular taxi will certainly begin at $38,790. The even more preferred 2500 SLE team cab 4x4 will have a beginning rate $1,900 less expensive than the outward bound model and also will certainly include these upgrades: a stronger, more effective 6.6-liter gas V-8, LED fronts lights, grip choose, extra haul as well as pulling ability, even more, sidesteps, and much more freight tie-downs in the bed. Rates for this certain model starts at $46,990. 

The top-of-the-line 3500 dually Denali 4x4 staff taxicab will certainly have a starting rate of $69,490 as well as consist of the 6.6-liter Duramax and also 10-speed transmission, surround-view cams, Multi-Pro Tailgate, as well as a lot more. Realistically, however, you can expect among the hefty haulers to obtain pretty near or over $80,000 with all packages inspected. Definitely not affordable by any action, but consider the upgrades being supplied for the 2020 model year, there's a solid worth suggestion to be made.
