What's New for the 2027 GMC Sierra 1500? Power, Screens, & Practical Surprises

A loaded trailer makes every part of a truck's drive matter. Getting moving, holding a steady line, easing down a grade, and positioning the trailer at your destination all call for different responses. The 2027 GMC Sierra 2500 HD brings updates to the systems involved in those moments, including its engines, steering, and brakes. For contractors and recreational trailer owners, those changes give this model year a clear focus: how the truck behaves under heavy loads. Here at Sam Boswell Buick GMC, we're taking a closer look at what's changing and how those updates relate to the trips you actually take. Steering and Braking Move Into the Spotlight Consider backing an equipment trailer into a narrow entrance. You're traveling slowly, making steering corrections, and controlling your speed with the brake pedal. The truck's response to those inputs matters just as much as its ability to pull the trailer down the highway. For 2027, the Sierra 2500 HD replaces hydraulic-assisted steering with segment-first rack-and-pinion electric power steering. GM designed the system for more precise steering, reduced kickback, and quieter operation. Steering assistance also operates independently of engine speed and brake-assist use. The practical appeal lies in consistency. Steering corrections are part of positioning a trailer, negotiating a work yard, and making a turn with a heavy load. A more predictable response can help you place the truck where you intend. Stronger Braking Hardware Braking receives substantial attention, too. The 2027 Sierra 2500 HD features a segment-first electronic braking boost system in a heavy-duty pickup. The new eBoost electronic brake-assist system works with larger, 14.6-inch front rotors and four-piston fixed front calipers. Upgraded rear brake hardware joins the package. GM describes improved heat capacity, reduced pedal travel, and more linear pedal feel among the changes made for the 2027 model year. Control When You Need It Most Think about approaching a turn after a downhill stretch. You want to judge your braking input smoothly as you prepare to change direction. The new hardware and pedal response address that part of driving, giving the steering and braking updates a shared purpose: control through changing conditions. On a test drive with our team, we encourage you to pay attention to steering effort during slow turns and how easily you can apply the brakes progressively. A New Duramax Changes the Diesel Equation The available diesel engine grows to an all-new 8.3L Duramax turbo-diesel V8. GM rates it at 555 horsepower and 1,230 lb-ft of torque. For comparison, the outgoing 6.6L Duramax only produced up to 470 horsepower and 975 lb-ft of torque. That represents an increase of 85 horsepower and 255 lb-ft of torque. For someone who routinely drives with a substantial trailer, this is a meaningful change to the powertrain choice. A business that regularly hauls equipment and a family that tows a large camper may both prefer diesel power, but their day-to-day driving needs can be very different. One might make repeated loaded trips between nearby sites; the other might spend extended periods towing on the highway. Before choosing, consider where the truck will spend its working hours and how often you'll use its capabilities. The new engine also marks a manufacturing change. GM developed this heavy-duty diesel in-house and will build it at its expanded DMAX facility in Brookville, Ohio. Its larger displacement is part of a new engine design rather than a change in badging. Gas Power Gets an Update as Well The standard 6.6L gas V8 for the 2027 model year increases to 412 horsepower and 472 lb-ft of torque. The previous version produces up to 401 horsepower and 464 lb-ft. GM also identifies improved low-end pulling power as part of the update. The gas engine, therefore, remains a relevant choice for buyers evaluating a heavy-duty truck around their own workload. Start with the loads you carry, then consider fuel preference and how the truck will be used between towing trips. A truck purchased for a combination of projects and occasional trailer travel has a different routine from one assigned to daily equipment transport. If you already own a heavy-duty truck, use your experience as a reference. Think about the routes where you wish for more pulling strength and the days when the truck spends most of its time unloaded. AT4X Gains Another Tool for Slow, Uneven Going The Sierra 2500 HD AT4X trims gains Terrain Mode for 2027. This new mode changes shift mapping and traction control while adding automatic braking for low-speed movement over uneven surfaces. Picture picking your way along a rough access route where you need to move forward a little, settle the truck, and choose your next line. Low-speed control is the central concern in that situation. Terrain Mode gives the AT4X another way to manage that kind of driving. Its Multimatic DSSV dampers also become larger than those on the previous model. GMC describes larger pistons designed to help the truck remain composed over washboards, rocks, and rolling bumps. These updates are particularly relevant if your routes regularly include rough surfaces. Consider the conditions you actually encounter: an uneven approach to a remote campsite, a rutted access road, or a gravel route traveled repeatedly. Thinking about the terrain you regularly encounter can help you decide whether off-road equipment is worth prioritizing in your truck. Read the Towing Number for the Truck You're Considering GMC lists maximum available towing of 23,100 lbs for the 2027 Sierra 2500 HD. That rating applies to a properly equipped configuration; it doesn't describe every truck in the lineup. For your own towing plans, put together a realistic load description: The trailer's loaded weight, including the equipment or travel supplies aboard. The hitch arrangement you intend to use. Passengers, tools, and other cargo riding in the truck. Tongue or pin weight placed on the truck by the trailer. Those details help you connect a published rating with an actual combination. For example, a camper's unloaded weight won't include everything you pack for a trip. Likewise, an equipment trailer's weight changes with the machine, attachments, and supplies you load. This is useful homework before comparing trucks. It allows you to discuss the configuration around a known task and check the relevant truck ratings, rather than treating engine output as a substitute for load information. Familiar Trailering Features Still Have a Job to Do Several features associated with Sierra 2500 HD ownership return alongside the mechanical updates. The available ProGrade Trailering System and up to 14 available camera views continue to remain as part of the truck's trailering technology. Camera views can provide different perspectives when hitching and maneuvering. During a demonstration, pay attention to the view that helps with the step you find most awkward. Aligning the hitch and positioning a trailer beside a building are different tasks, and each benefits from seeing the relevant area. The available 13.4-inch infotainment screen, 12.3-inch digital driver information center, and 15-inch head-up display also continue to be available for the 2027 model. Their usefulness depends on how you interact with them. Try the controls you'll use frequently and check whether the displayed information is easy for you to read from your driving position. A Model Year Focused on the Working Drive GMC expects the 2027 Sierra 2500 HD to become available in late 2026. The latest upgrades and changes give buyers more of a reason to be excited for its debut: stronger engine options, revised steering and braking, and the new Terrain Mode for low-speed capability. At Sam Boswell Buick GMC, we can help you relate those changes to your regular loads and routes. Bring the details of the work you need the truck to do. They'll make the conversation about your next Sierra 2500 HD more meaningful. If you're ready to hop into the driver seats of this heavy-duty pickup, visit us today!

The GMC Sierra has always been popular amongst off-roaders and hard workers, making the powertrains a focus for shoppers. For 2027, we get two new engines and an updated off-road trim. The New Engines One of the biggest changes for the 2027 Sierra 1500 is taking place under the hood. For 2027, GMC has created two new small-block V8s — a 5.7L and a 6.6L option. For reference, the 2026 offerings were a 5.3L and 6.2L V8. The new V8s have been engineered with improved combustion, cooling, and control systems that deliver the ideal blend of smooth performance, powerful capability, and off-road reliability. These engines are the right fit for a variety of drivers and environments, from paved roads to jobsites and challenging trails. The 2027 Sierra 1500 retains a TurboMax engine, delivering best-in-class standard torque, as well as a Duramax diesel engine, delivering a blend of exceptional towing power and solid fuel efficiency. Whatever your tasks or trips look like, there's a 2027 Sierra 1500 engine that can handle them. The Improved Off-Road Trim GMC has also made the Sierra's off-road trim, the AT4X, better than ever. For the 2027 model year, the model gets: New 35-inch Goodyear Wrangler Territory Mud-Terrain tires. Their open-tread design, reinforced shoulders, and unique pitch pattern enable these tires to deliver traction and toughness when it counts. Multimatic Jounce Control Dampers. These high-performance dampers are designed for turbulent conditions, providing control when the road gets rough — even at high speeds. Front and rear e-locking differentials that work in conjunction with selectable drive modes to minimize wheel slippage and keep you in command on the trails If your Montgomery adventures take you off the pavement and into the wild, the new AT4X is ready for your rowdiest plans. The Cabin Let's move inside, where you'll find a redesigned cabin, made to make every mile feel like a slice of the good life. Panoramic Sunroof An available panoramic sunroof lets you enjoy beautiful Montgomery days. Let the sunshine in by opening the power sunshade, or shut it out when your passengers want to use devices or enjoy a nap. Use the tilt feature to let in a light breeze, or slide a panel fully back to let in a stronger gust of wind. MultiPro Center Console The new MultiPro center console turns the area between the front two seats into a multifunctional storage and workspace. The console can fold open into an expansive work surface, giving you a place to fill out paperwork, look over blueprints, or finalize contracts inside your cabin. The console also has USB charge ports for passenger devices. Bose Premium Series Audio System The Bose Premium series, complete with 16 speakers and front head restraint-mounted speakers, turns your cabin into a concert hall on wheels. Every corner of your truck's interior will be filled with high-definition sound. Whether you're listening to music, a podcast, or an audiobook, you'll feel like the artists or narrators are in the room with you. The Displays You'll never feel uninformed or out of touch in the 2027 Sierra 1500 thanks to its multitude of well-placed displays. 16.3-Inch Diagonal Infotainment Screen A 16.3-inch diagonal infotainment screen sets the stage, serving as your command center for looking up directions, changing the playlist, checking messages, and much more. With a large face and crisp graphics, it makes turn-by-turn directions easy to see at a quick glance. The infotainment screen also features articulation, so you can adjust it for optimal visibility. Plus, it has a hidden storage compartment behind it, giving you another convenient place to organize smaller everyday essentials while helping keep the cabin tidy. 11.5-Inch Diagonal Front Passenger Screen Then, there's the 11.5-inch diagonal front passenger screen. Your co-pilot can entertain themselves via streaming apps or help you navigate by pulling up directions. They can also play DJ, changing the song or fast-forwarding through the audiobook. For a sleek aesthetic, close the passenger screen cover. 12.2-Inch Diagonal Driver Information Center Looking just beyond the steering wheel, you'll find the 1 2.2-inch diagonal Driver Information Center. This is where you'll find important vehicle information. And you can configure it to show you the stats that matter most to you, whether that's safety alerts, engine performance, or something else. 15-Inch Diagonal Head-Up Display Want journey stats directly in your line of sight, so you don't need to take your eyes off the road for even a second? That's where the 15-inch diagonal multicolor head-up display comes in. It projects information such as your speed, navigation information, and safety alerts directly onto the windshield in front of the driver. 8.5-Inch Diagonal Rear Camera Mirror Finally, an 8.5-inch diagonal rear camera mirror gives you one more way to keep an eye on the back of your truck. It turns your rearview mirror into a display for your rearview camera, providing a wide, unobstructed view of everything happening behind your vehicle.

The GMC Yukon's performance resume is tough to ignore, with the full-size model among the more muscular options in the SUV segment. From the V8 base engine with its considerable towing capacity to a Duramax turbo-diesel that is capable of producing 495 lb-ft of torque, you'll never be hurting for power when you choose a GMC Yukon for sale in Enterprise. The SUV is also one of the more premium models in the competitive class, with even the base model featuring heated seats, power-folding third-row seats, and a ten-speaker Bose premium sound system. It's this commitment to quality that has long separated the GMC Yukon from the rest of the mass-market models, and the SUV only improves as you explore the rest of the lineup. Upper trims and available equipment packages add everything from a panoramic sunroof and premium leather upholstery to an Air Ride Adaptive Suspension and ventilated and massaging seats. The SUV's AT4 and AT4 Ultimate trims transform it into an adventure-ready off-road rig, but it's the Yukon's interior tech, towing ability, and roster of advanced driver-assistance systems (ADAS) that really give the SUV an edge in the competitive category. Let's track some of the latest changes, explore a few of the SUV's more unique features, and learn how the GMC Yukon has become the model to beat in the full-size segment. Ready to Put in Some Work Full-Size SUVs hold a key advantage over their smaller, crossover-based competitors, especially when it comes to towing ability. The Yukon combines the passenger space of a traditional SUV with the sort of low-end power that's usually limited to the pickup segment, giving owners the opportunity to put in a hard day's work while still enjoying all the benefits of a comfortable, family-friendly vehicle. Best of all: you don't have to break the bank to enjoy the Yukon's most capable towing configuration. The SUV's 5.3L V8 base engine tops the charts for towing capacity, providing buyers with 8,400 lbs of pulling power. The 6.2L V8 isn't too far behind at 8,200 lbs, and while the Yukon's 3.0L Duramax turbo-diesel I-6 brings up the rear at 8,100 lbs, it makes up for it by leading the lineup in fuel economy. Of course, it takes more than a robust engine to tackle some of the bigger towing tasks you might encounter. Luckily, GMC has you covered with the Max Trailering Package. From a Hitch View camera that makes it much easier to line up the hitch and trailer coupler to an integrated trailer brake controller and an upgraded version of the blind-spot intervention system that's designed to account for the length and width of an attached trailer, the Yukon makes it easy to take advantage of the SUV's full towing capacity. The Max Trailering Package is available on every 2027 trim, and even includes Smart Trailering features that give owners the opportunity to monitor important trailer-related data right on the Yukon's standard 16.8-inch touchscreen infotainment system. The Yukon also represents one of the more spacious options in the full-size segment, with the standard version providing Enterprise drivers with 122.8 cu.ft. of cargo space. Whether your typical time behind the wheel involves long road trips, big grocery hauls, or serving as a shuttle between various sports practices and after-school activities, you'll never be hurting for cargo space when you choose the Yukon. Looking for even more room? GMC is one of the few brands to offer an upsized version of its largest SUV. The Yukon XL leverages an extended wheelbase to boost its cargo capacity to 144.5 cu.ft., tying it with its Chevy Suburban cousin for the lead in the full-size segment. A Tech-Forward Interior A recent 2025 mid-cycle refresh saw the Yukon make some important updates to the interior and quickly become one of the segment's more cutting-edge options. It all starts on the dashboard, where drivers will discover a 16.8-inch touchscreen infotainment display. The screen isn't the largest in its class, but it does represent a notable upgrade over the underwhelming options found on many base models. Rather than forcing drivers to opt for higher trims and optional packages, GMC has made the large infotainment display standard across the entire lineup. You'll never be short on screen time with the Yukon Elevation, which features an 11-inch digital gauge cluster, plus a wireless phone charger, a ten-speaker Bose premium sound system, and ample USB ports throughout the cabin. The available Technology Package adds two more screens to the mix: a 12-inch head-up display and a digital rearview mirror that lets drivers see through even the most jam-packed cargo area. The Yukon doesn't reserve the best features for front-row passengers. GMC knows what it takes to build a modern family vehicle, especially when it comes to keeping the kids occupied. The Elevation, AT4, and Denali trims are all available with a rear-seat entertainment system, while the feature comes standard on the AT4 Ultimate and Denali Ultimate trims. The rear-seat entertainment system turns the Yukon's second row into a media room on wheels, complete with dual 12.6-inch touchscreen displays, Bluetooth connectivity,  and access to a variety of entertainment options. The system can stream content from popular apps like YouTube and Hulu, and can even browse the web thanks to the Yukon's built-in Wi-Fi connection. Best of all, each user can select their own content, which means you'll spend a lot less time defusing disputes between siblings. The co-pilot can easily manage the system from the front row, and the rear-seat entertainment feature even includes HDMI and USB ports to accommodate gaming consoles or streaming devices. The Yukon even includes a newer feature that's sure to provide drivers with some priceless peace of mind, whether they're cruising around Enterprise or away from their vehicle. The Yukon's Surround Vision system employs a network of connected cameras to give drivers a full, 360-degree view of their SUV and the surrounding area, but three newer camera features add an important surveillance function that could prove valuable in the event of an accident or break-in. The Surround Vision Recorder leverages the Yukon's exterior camera to act as a sort of factory-installed dash cam, while the Security Recording function is designed to automatically record interior footage whenever the vehicle's alarm is activated. This same interior camera also allows drivers to keep an eye on backseat passengers or delicate cargo with the Cabin Glance feature, which delivers a live feed directly to the dashboard infotainment display. A Safer Choice for Families Safety never takes a backseat when you're in the market for your next family vehicle. The Yukon's sheer size, passenger space, and impressive slate of infotainment tech have long made it one of the most popular models in the full-size segment, but it's the SUV's suite of advanced safety tech that really seals the deal for those looking to enjoy a more confident driving experience. Just take the entry-level Elevation trim, for instance. While other automakers are content to limit many of their best ADAS to upper trims and optional equipment packages, GMC provides buyers in Enterprise with a generous package that underscores the Yukon's considerable value. The base model is equipped with a comprehensive suite of standard ADAS features, as well as a number of premium features designed to address key safety concerns. Blind Zone Steering Assist is one example; it automatically steers the SUV back into its lane when it detects an oncoming vehicle lurking just outside your view. It's the same story when it comes to the Yukon's Enhanced Automatic Emergency Braking, which warns drivers of an impending accident and can even apply the brakes under certain conditions. The SUV's adaptive cruise control system marks a notable improvement over the standard system found in most base models, as does the Yukon's Enhanced Automatic Parking Assist feature. A set of parking sensors is par for the course on an entry-level trim, but GMC has gone above and beyond to provide drivers with a well-rounded ride that will never leave you feeling nickel-and-dimed. The Yukon's safety resume only improves as you climb the trim ladder, but it's the Denali model that sees the biggest upgrade for the 2027 model year. While buyers once had to opt for the range-topping Denali Ultimate to enjoy GM's Super Cruise hands-free driving technology as a standard feature, the system is now included on every Yukon Denali model. Super Cruise allows drivers to enjoy a true hands-free experience on more than 600,000 miles of compatible highways across the United States and Canada. Never Settle for Second Best at Sam Boswell Buick GMC It's the GMC Yukon's versatility that really sets it apart in today's full-size SUV market. While other models tend to occupy a specific niche, the Yukon is a true jack-of-all-trades. Whether you're searching for a feature-packed base model, a serious towing machine, or a spacious SUV that was crafted to meet the needs of today's busy Enterprise families, every driver will find something to love about the 2027 Yukon. The expanded availability of GM's Super Cruise system gives the Yukon a clear advantage over many of its rivals, and the Surround Vision Recorder, Security Recording, and Cabin Glance functions are sure to appeal to those who appreciate the latest in-vehicle tech, but these aren't the only upgrades to keep in mind when you browse our selection. The Yukon has also been treated to some new 20- and 22-inch wheel designs for 2027, as well as a new Coastal Dune exterior color that gives the off-road AT4 and AT4 Ultimate trims an even more adventure-ready appearance. When you're ready for a new full-size SUV that doesn't ask you to make any compromises, you'll find the new 2027 GMC Yukon waiting for you here at Sam Boswell Buick GMC.
