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 4×4 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 4×4 trails we located near Grand Teton National Park. Distinctly, the transfer instance provides both all-wheel-drive, 4×4 high range, and also 4×4 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 4×4 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 4×4 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.
