The Chevrolet Silverado and GMC Sierra really don't have many traits that set them apart, aside from different front-end styling. But GMC is hoping the new 2019 Sierra, making its debut today, will be able to distinguish itself from its Chevrolet brethren.
To do this, GMC has two new features that are exclusive to the Sierra. First is the CarbonPro bed. Optional on the Denali, the bed is comprised of lightweight carbon fiber composite panels for the inner panels and floor. Not only does it promise "best-in-class dent, scratch and corrosion resistance", it also drop 62 pounds out of the Sierra's curb weight. Second is the MultiPro Tailgate that offers "six unique functions and positions
" such as standing workstation.
The Sierra's exterior takes a bold approach with a larger front grille and C-Shaped headlights. Denali models appear to have a lot of chrome trim. 22-inch wheels are standard equipment on the Denali and SLT. We don't know much about the exteriors for lesser Sierra models as GMC is focusing on the Denali and SLT models for the time being.
Like the Silverado, GMC has focused on cutting weight in the 2019 Sierra - up to 360 pounds depending on the configuration. Aluminum panels are in use for the doors, hood, and tailgate.
Don't expect any drastic differences between the Sierra's and Silverado's interior aside from some additional chrome trim. The Sierra does come with some interesting tech including a full-color heads-up display, a trailering smartphone app that allows a driver to check the lights, trailer tire pressures, and perform electrical diagnostics; and hitch guidance system to make hooking up a trailer easier.
Engines will include the 5.3L and 6.2L V8s, and the all-new 3.0L turbodiesel inline-six.
We'll hopefully have more details and pictures as GMC will be holding an event later tonight in Detroit. The 2019 Sierra arrives at dealers this fall.

GMC Introduces the Next Generation 2019 Sierra
Commanding design, segment-leading technologies redefine premium truck
DETROIT — GMC is taking its most popular pickup truck to the next level with the completely redesigned 2019 Sierra Denali and SLT.
Distinguished by bold design and segment-leading technologies, the next generation Sierra Denali once again redefines the premium pickup, while advancing Denali’s legacy as the pinnacle of GMC design, capability and refinement.
“GMC ignited the premium truck segment 17 years ago with the original launch of the Sierra Denali,” said Duncan Aldred, vice president of Global GMC. “The next generation 2019 Sierra Denali establishes a new benchmark in capability and refinement. It exemplifies precision in every detail.”
Powerful proportions and distinctive Denali design help define the Sierra’s unmistakable exterior, while the driver-focused cabin strengthens the brand’s reputation for refinement with premium materials, improved interior space and innovative storage solutions.
The 2019 Sierra Denali affirms its position as the most premium Sierra ever with segment-leading technologies and exclusive features, including:
GMC Exclusive, Industry-first MultiPro Tailgate is the most innovative pickup tailgate ever, with six unique functions and positions offering enhanced second-tier loading and load-stop solutions, a standing workstation and easier access to items in the box. GMC Exclusive, Industry-first Carbon Fiber Pickup Box, the CarbonPro, was developed to increase durability, efficiency and functionality while offering best-in-class dent, scratch and corrosion resistance, making it the most durable pickup box in the segment. All-new ProGrade Trailering System with Trailering App offers a connected comprehensive suite of trailering technology that brings more confidence to the towing experience than ever before. Segment-first Multi-Color Head-Up Display projects key, customizable vehicle data on the windshield in a 3x7-inch display to help drivers keep their eyes on the road. Segment-first Rear Camera Mirror offers an optimized view via an available dual-function interior mirror that expands vision to overcome common visual obstructions like occupants or cargo. This next generation system features a higher resolution camera and display and the ability to tilt or zoom the view. The redesigned Sierra Denali offers a full suite of available advanced safety features, along with exclusive chassis technologies such as Adaptive Ride Control.
“The heritage of the GMC brand is rooted in full-size trucks, of which the Sierra is our cornerstone, with our SLT and Denali models contributing 87 percent of our total crew cab sales,” Aldred said. “The next generation Sierra caters to these unique customers who demand a premium, innovative truck that supports their professional and personal passions.”
A commanding presence
The 2019 Sierra Denali debuts a profound new GMC design. A taller, more confident stance gives Sierra Denali powerful proportions complemented by hallmark details such as a chrome grille with a sharp, precise dimensional pattern that epitomizes the truck’s attention to detail.
“The next generation Sierra Denali has a deliberate, commanding presence,” said Matt Noone, director of design, GMC Exteriors. “Its unmistakable design embodies the essence of GMC, while advancing the brand’s core styling elements — rooted in inherent capability — with a new expression of its signature cues.”
Sierra shows refinement and strength through a larger, more-dominant upright grille, a taller hood, and a bolder, more pronounced take on GMC’s C-shaped lighting signature.
Advanced lighting technology distinguishes the Sierra Denali from every other truck on the road. GMC’s front lighting signature is conveyed through a prominent “light blade” that delivers uniform LED illumination for the daytime running lamps. LEDs are also used for the headlamps, taillamps, fog lamps and other illuminative elements, with lenses constructed from durable material with an almost crystalline quality.
The truck is larger than the previous truck in virtually every dimension, and the larger grille and dramatic lighting accentuate its broad-shouldered stance. The wheels are pushed closer to the corners and wear larger diameter tires. Denali features available 22-inch Ultra Bright aluminum wheels; the SLT model offers its own unique 22-inch dark aluminum wheels finished with chrome accents.
New, more prominent badging includes a bold DENALI nameplate on the tailgate —expressed in a new block-style typeface that echoes the truck’s strong proportions — below the signature GMC identification.
An elevated interior refined
The Sierra Denali’s new interior builds on the refinement and sophistication that have become synonymous with Denali, topping the segment with best-in-class front head- and legroom (maximum), providing a more spacious, driver-centric environment finished with premium materials.
Putting the driver at the center of experience starts with a higher seating position that offers a confident view behind the wheel. The optimized ergonomics emphasize easy, intuitive interaction with the vehicle’s technologies, such as the all-new Trailering App and segment-first Head-Up Display.
Denali-exclusive materials — including premium leather-appointed seating, authentic open-pore wood trim and dark-finish aluminum decor — help raise the interior to a new level of refinement. The exclusive leather appointments have a distinctive, large-pebbled grain with a contrasting stitch pattern that is both premium in appearance and touch without sacrificing durability, and the wood trim features an open-pore texture evocative of hand-planed furniture.
When it comes to the space and storage vital to truck customers, the 2019 Sierra’s crew cab has nearly 3 inches of additional rear-seat legroom compared to the current model. The outboard rear seat backs open to reveal rectangular storage spaces large enough for storing tablets or laptops, tie-down cords, umbrellas or other important accessories.
Groundbreaking cargo box capability and materials
The next generation 2019 Sierra debuts a GMC exclusive, industry-first MultiPro Tailgate that is the segment’s most innovative tailgate ever. Standard on SLT and Denali, the MultiPro Tailgate features six unique functions and positions, offering enhanced second-tier loading and load-stop solutions, a standing workstation mode and easier access to items in the box.
The MultiPro Tailgate also incorporates a step entry and egress mode that, when paired with the assist handle, offers both step and seated functionality, with a maximum weight capacity of 375 pounds (170 kg). Ease of use is enhanced with two buttons on the tailgate handle that allow convenient inner gate release.
This multifunctional tailgate offers proven strength and durability, having undergone more testing and validation than any tailgate in GM’s history. Sierra is the first and only truck to offer the MultiPro Tailgate, providing premium truck customers the ultimate flexibility. MultiPro Tailgate will be standard on Denali and SLT.
The cargo boxes also offer best-in-class cargo volume — 63 cubic feet (1,784 liters) on the short box, as well as additional tie-downs and a new, available 110-volt power outlet. The bed continues to be made of roll-formed, high-strength steel, yet a revised alloy offers 50 percent more strength than the current model.
The 2019 Sierra Denali will offer, later in the model year, an available GMC exclusive and industry-first carbon fiber box — the CarbonPro — developed to increase durability, efficiency and functionality of the truck. It replaces the standard steel inner panels and floor with a lightweight, purpose-designed carbon fiber composite that offers best-in-class dent, scratch and corrosion resistance, making it the most durable pickup box in the segment.
“In 116 years of making GMC pickup trucks, our industry-first carbon fiber box is the toughest and most durable pickup box we have ever made,” Aldred said.
The new CarbonPro box is 62 pounds (28 kg) lighter than the steel version, and is one example of GMC’s strategic use of materials in engineering the Sierra. The strategy also incorporates aluminum for the doors, hood and tailgate, while relying on steel for the fenders, roof and standard cargo box to shave up to 360 pounds (163 kg) from Sierra compared today’s model.
ProGrade Trailering System with Trailering App
The 2019 Sierra offers a more confident towing experience thanks to GMC’s new ProGrade Trailering System, standard on Denali and SLT. The trailering system includes an all-new Trailering App featuring a Pre-Departure checklist, Maintenance Reminders, Trailer Light Test, Trailer Electrical Diagnostics and Trailer Tire Pressure and Temperature Monitoring.
Many of the Trailering App’s functions, including the lighting test and pre-departure checklist, are also available with the MyGMC app on compatible Android and iOS smartphones, a feature that offers great convenience when outside the truck or trailer.
The next generation Sierra also offers Hitch Guidance with Hitch View and Auto Electric Park Brake to help with perfect positioning when hitching. The available side view cameras and a trailer-mounted HD camera provide additional assistance when driving down the road or in reverse. With exclusive Trailer Theft Detection, owners can receive text and mobile alerts from OnStar when the trailer has been detached from the truck without permission.
Seamless, driver-focused technology has long been a Denali standard, and the 2019 Sierra Denali establishes a new benchmark by incorporating purposeful technologies.
These technologies work together to increase functionality and enhance comfort and convenience. Highlights include:
Segment-first Multi-color 3x7 Head-Up Display: The 2019 Sierra is the first full-size truck to offer this technology, which projects key vehicle information on the windshield within the driver’s line of sight. Advanced GMC infotainment: This new, dynamic platform offers a smartphone-like experience with an intuitive interface, faster response and improved voice recognition. Sierra Denali’s standard 8-inch diagonal system includes navigation. Segment-first Rear Camera Mirror: This available dual-function interior mirror offers an optimized camera view that can help the driver’s view around potential vision obstructions such as occupants or cargo, while also offering a greater field of vision. This next gen system features a higher resolution camera, a higher resolution display and the ability to tilt or zoom the view. A conventional mirror view is also available. Surround Vision: Offering a bird’s-eye view of the truck, this available feature displays an overhead image on the infotainment screen, helping the driver detect potential obstacles when backing up, including when trailering. Full suite of advanced safety features: The 2019 Sierra Denali offers a full range of available advanced safety features, including Side Blind Zone Alert, Pedestrian Detection and Low Speed Forward Automatic Braking. Sierra performance
New versions of the proven 6.2L and 5.3L V-8 engines will be joined by an all-new 3.0L inline-six turbo-diesel engine, expanding the powertrain lineup for the 2019 Sierra.
The 5.3L and 6.2L engines feature stop/start technology and new Dynamic Fuel Management that enables the engine to operate on one to eight cylinders, depending on demand, to optimize power and efficiency. The new diesel builds on GMC’s expertise with Duramax turbo-diesels offered in Sierra HD and Canyon models. The available 6.2L and 3.0L engines are paired with a 10-speed automatic transmission.
Sierra Denali features an exclusive Adaptive Ride Control suspension system designed to provide premium driving refinement with exceptional responsiveness. It employs sophisticated sensors to monitor road conditions and chassis responses in real time, enabling adjustments to active dampers every 2 milliseconds.
Coming this fall

It won't be too long before GMC reveals its counterpart to the brand new 2019 Chevrolet Silverado. Automotive News reporting that GMC will be holding an event on March 1st in Detroit to reveal the 2019 Sierra.
Expectations are that the Sierra will be differentiated from its Silverado sibling. Previous spy shots seem to indicate this with a different front end treatment on the Sierra. There is talk that the Sierra will also get some changes for the interior.
The 2019 Sierra specs will likely match up to the Silverado with a longer wheelbase, weighing up to 450 pounds less than the outgoing model, spacious cargo bed, and an available power tailgate. Six powertrain combinations, including a 3.0L Duramax turbodiesel inline-six, and 5.3 and 6.2L V8 engines.

GMC had a bit of a surprise for the Dubai International Motor Show with the Desert Fox Middle East truck concept.
Desert Fox was a special package available on the 1977 GMC C/K 1500 pickup that featured a tan (Buckskin) exterior color with color stripes running along the sides and hood. The package also featured a brush guard, bed mounted sports bar, additional lights, and tan colored wheels. This package was also available for the Jimmy SUV.
This Sierra 1500-based concept brings this package into the modern era with the same paint color and stripe layout. It also comes outfitted with some off-road goodies such as an off-road bumper with a winch, beadlock wheels wrapped in desert-terrain tires, bed-mounted sports bar with LED lights, skid plates, and a new exhaust system. No mention of a powertrain but we're thinking it could the 5.3L V8.

It is quite amazing how in the past few years, the humble heavy-duty pickup has morphed into a prized luxury vehicle. You might think that I am crazy for writing this, but consider how in the few years, truck manufacturers have been tailoring their models to appeal to a new audience. From new trim levels that focus primarily on luxury to new features that one would expect to find in an expensive sedan such as massaging front seats and high-quality leather. That doesn’t mean these luxury pickups have forgotten their main priority; to shoulder the weight of the world in terms of hauling and towing.
Recently, we spent a week in the GMC Sierra Denali 2500HD and Ram 2500 Laramie Longhorn to get a reading on where luxury heavy-duty trucks currently stand.
Neither one of these trucks has gone through any significant changes since we last reviewed them. The 2500HD comes with a new hood scoop if you option the Duramax V8 turbodiesel, while certain Ram models such as our tester come with a new grille insert featuring “RAM”.
The two trucks could not be more different in terms of design elements. The Denali is more modern with a mesh grille, square headlights with LED strands, and a seemingly endless amount of chrome trim. We've found ourselves wondering if we could blind anyone while driving if the sun hit the Denali in just the right way. Meanwhile, the Laramie Longhorn feels right at home on a farm or ranch. The two-tone paint scheme of brown and beige really sets off the Ram 2500, along with the meaty 18-inch chrome wheels. The ‘RAM’ grille is a bit much, but at least it doesn’t come with large chrome lettering on the tailgate that can be reportedly seen from space. Our test truck came with Ram Box storage system. We like the additional storage and ability for the boxes to be locked, but it also means the bed is slightly narrower than a truck without it.
At one time, Sierra Denali was considered the pinnacle of luxury for pickup trucks. But now it pales in comparison to the likes the Ram and Ford. The Sierra Denali has the basics such as leather upholstery and stitching on the dash. But that’s about it as there isn’t the option of wood or aluminum trim. Instead, you get painted and faux-chrome like on other Sierra models. A lack of special touches hurt the Denali as well. It would be nice if there was some exclusive feature for the Denali such as a premium audio system or massaging seats.
On the upside, the dashboard is laid out in a logical fashion and controls are within easy reach. Both rows of seats provide excellent support for long trips and plenty of space for most passengers. The Sierra also earns points for having numerous USB ports. Getting in and out of the Sierra 2500HD is slightly easier than the Ram 2500 as the cab height is slightly lower.
Ram does a better a job in terms of luxury appointments. The Laramie Longhorn features what Ram calls ‘Natura Plus’ leather that feels quite nice when you run your hand across it. Real wood is used on the steering wheel and center stack trim to set it apart from other trims. Rear seat passengers will like the availability of heated seats, something not available on the Denali. There are other touches such as different background for the gauge package and seat pockets that are designed to look like saddle bags. It might look ridiculous to some, but Ram deserves some credit for trying to stand out.
Like the Sierra, Ram has a well-laid out dashboard with controls in the place you would expect. Seats aren’t as comfortable as the Sierra, but the 2500 does match it in terms of interior space. The Ram 2500 is somewhat harder to get in as feel like to you have to take a running leap, despite there being entry rails and grab handles. It is also quite the drop when getting out.
If there is an area that the Sierra leapfrogs the Ram, it is in technology. The Denali comes with an eight-inch screen featuring GMC’s Intellilink system as standard. This system has been improving since we first tried it a few years ago with improved performance and better stability. The only thing that needs to fixed is the slow response of the navigation system when first launched. Using the system is easy thanks to a simple interface and physical buttons underneath the screen. The addition of Apple CarPlay and Android Auto give Intellilink more of an edge over other systems.
Ram’s UConnect system was for a time considered one of the best systems thanks to a large screen and interface that offers large touchscreen buttons. It still retains these plus points, but it looks quite dated to the system found in the Sierra. A lot of this comes down to the interface which hasn’t changed since UConnect was launched a few years ago. There is a new version of UConnect that FCA has implemented into various models such as the Pacifica and the 2017 Dodge Charger that brings an updated look along with Apple CarPlay and Android Auto compatibility. Sadly, the Ram 2500 misses out on this and it is unclear whether it will get in this current-generation or in a redesign.
Both trucks came with their respective optional diesel engines. For the Sierra Denali 2500HD, it is an updated 6.6L Duramax turbodiesel V8 offering 445 horsepower and 910 pound-feet of torque. Ram sticks with 6.7L Cummins turbodiesel inline-six with 370 horsepower and 800 pound-feet of torque. Both engines come paired with six-speed automatic transmissions, but the Ram is available with a six-speed manual.
On paper, the Sierra Denali 2500HD smokes the Ram 2500 Laramie Longhorn and this plays out in the real world as well. The Duramax gets the Sierra 2500HD up to speed at a surprising rate. It feels more like a muscle car thanks to an abundance of low-end torque and being the lightest truck in the class - 6,532 lbs for a 4WD crew cab and 6’6” box vs. 7,625 lbs for the Ram 2500 when similarly equipped. A lot of these performance gains come from changes GM made to the Duramax V8 for 2017 with most of the engine’s internals being replaced and new cool air system with a hood vent. Aside from increased power, the changes also affect how quiet this engine is. Start the engine up and you’ll faintly hear the diesel clatter from inside.
The 6.7L Cummins cannot match the Duramax in outright performance. It takes about a second or two longer to hit the same speed as the Duramax. The large deficit in power and being slightly heavier than the Sierra 2500HD are the main reasons as to why. Not helping matters is the Cummins being quite louder than Duramax. At idle, it sounds like a semi-truck.
Neither truck is rated by the EPA as they're exempted from testing due to their heavy weight. In our week-long evaluation, both trucks returned an average of 15 mpg in mostly city driving.
Ram shines here as the maximum tow rating for our particular configuration (crew cab, 6’6” bed, and 4WD) comes in 17,200 lbs. GMC comes up short at 13,000 lbs in the same configuration.
Ride and Handling
While the Sierra Denali 2500HD may trail the Ram in terms of towing, it runs away when it comes to the ride. Despite sticking with a set leaf-springs in the rear, the Sierra 2500HD does a better job smoothing out bumps than the Ram’s coil-spring setup when the beds are empty. Fill them up and it becomes a dead heat in terms of ride quality. Ram does claw some points back as body motions are controlled better when turning and the steering doesn’t wander as much when driven on the highway.
Noise isolation goes to the GMC as there has been a fair amount of work done on adding more sound insulation to the truck, along with the improvements made to the engine.
Both of these trucks are expensive propositions. The Ram 2500 Laramie Longhorn comes in at $73,310 as equipped and the Sierra Denali 2500HD is slightly less at $70,540. The key reason for the high prices are the optional diesel engines - $8,700 for the Ram and $9,550 for the Sierra. Considering how much power you get, we give this to Sierra by a hair.
If we consider these two trucks as luxury models, then we would rank the Ram 2500 Laramie Longhorn ahead of the Sierra Denali. It makes passengers feel special with various touches such as the unique leather for the trim and heated rear seats. But both trucks pale in comparison to all-new Ford F-Series Super Duty that brings massaging seats and impressive material qualities in its top trim.
But when it comes to heavy-duty truck things, the GMC Sierra Denali stands above. While the Ram 2500 may have the more impressive towing numbers, the Sierra fights back with the more powerful diesel engine, better NVH containment, and a more comfortable ride. Hence why it takes this comparison test by a very narrow margin.

Here is some food for thought: over 50 percent of Yukon/Yukon XL models sold are Denalis. A pretty nice number and one that makes a fair amount of profit for GMC. But that also means GMC needs to keep Denali models up to date to keep those sales up.
For 2018, GMC is making some updates to the Denali trim for the Yukon family. First up is a new multidimensional chrome grille featuring grille shutters to improve fuel economy.
"The new grille, which is flanked by HID headlamps and LED Signature Lighting, advances the design legacy established with the very first Yukon Denali in 1999. It’s a more exciting and sophisticated design, while remaining instantly recognizable as part of the GMC Denali family," said GMC Global Exterior Design Director Matt Noone.
Under the skin is a new 10-speed automatic transmission featuring wider, 7.39 overall gear ratio spread that will help make the Yukon/XL Denali more efficient. A 6.2L V8 engine offering up 420 horsepower is standard.
The updated Yukon/XL Denali arrives at dealers this fall.

2018 GMC Yukon Denali Elevates Style, Refinement
The ultimate expression of Professional Grade gets bold refresh on GMC Yukon models DETROIT – GMC is elevating the 2018 Yukon Denali lineup with styling and trim enhancements, as well as a new, advanced 10-speed automatic transmission.
A new, sculpted grille design distinguishes the Yukon Denali, while new Mastique Ash real wood trim adds depth and richness to the interior.
The new Hydra-Matic 10-speed transmission — paired with Yukon Denali’s 6.2L V-8 engine — enhances refinement with world-class shift smoothness, responsiveness and quietness.
“Yukon Denali has always matched style with substance, and the enhancements for 2018 advance that legacy,” said Duncan Aldred, vice president of Global GMC. “The foundational elements of exclusive design, premium touches and uncompromising capability have made Yukon Denali an icon for nearly 20 years.”
Multi-Dimensional Grille Design
GMC designers evolved the iconic Denali grille with a multidimensional, sculpted interpretation that, like other contemporary GMC elements, was designed in a layered manner. It’s a theme seen in other new GMC models such as the Acadia and Terrain.
“The new grille, which is flanked by HID headlamps and LED Signature Lighting, advances the design legacy established with the very first Yukon Denali in 1999,” said Matt Noone, director, Global GMC Exterior Design. “It’s a more exciting and sophisticated design, while remaining instantly recognizable as part of the GMC Denali family.”
In addition to a more sophisticated appearance, the new grille offers greater airflow to the radiator. Active aero shutters behind the grille close in certain conditions on the highway to reduce aerodynamic drag and enhance efficiency.
10 Speeds, Refined Performance
The Yukon Denali’s new 10-speed automatic leverages the engineering experience of General Motors’ multispeed transmissions to deliver improved performance.
A wider, 7.39 overall gear ratio spread, compared to the Yukon Denali’s previous eight-speed automatic, enables a lower numerical top gear ratio and contributes to greater efficiency.
The transmission’s optimized gearing and proprietary controls allow the 6.2L V-8 engine to deliver a winning combination smooth operation and precise response.
Standard and available features include:
420-hp 6.2L V-8 engine with direct injection and Active Fuel Management StabiliTrak electronic stability control, tow/haul mode, trailer sway control, auto grade braking and hill start assist Magnetic Ride Control for improved body motion control Standard 20-inch wheels and available 22-inch wheels Automatic locking rear differential Four-wheel-disc brakes with Duralife™ brake rotors Active Noise Cancellation for a quieter interior 8-inch diagonal GMC Infotainment system with Navigation includes Apple CarPlay and Android Auto capability Standard 8-inch diagonal customizable driver display with head-up display Multiple USB ports and accessory power outlets, including a 110-volt three-prong outlet, to support electronic devices OnStar Basic Plan1 is standard for five years and includes access to an in-vehicle 4G LTE Wi-Fi hotspot2 and select features via the myGMC mobile app3 Wireless phone charging Heated and ventilated driver and passenger seats, heated second-row seats Hands-free programmable power liftgate The Denali trim accounts for well more than half of all Yukon sales. It is offered in Yukon and Yukon XL models, with the XL featuring a 14-inch-longer wheelbase (20 inches longer overall), for increased third-row legroom and more than double the cargo room behind the third-row seat.
The 2018 Yukon Denali goes on sale this fall.
