The 2026 GMC Sierra 2500 HD AT4 comes equipped with a factory-installed 1.5-in suspension lift, skid plates to protect key underbody components, Multimatic® DSSV Dampers, Rancho® shocks, and an off-road-tuned chassis that gives you added ground clearance when the pavement ends. These aren't cosmetic upgrades - they are functional features that make a difference when terrain gets uneven or unpredictable. The AT4 also brings a locking rear differential and hill descent control, two features that are important when you are driving on loose gravel, steep grades, or through mud. Paired with all-terrain tires, the 2026 GMC Sierra 2500 HD AT4 is engineered to go further than a standard heavy-duty truck. Heavy-Duty GMC Truck Performance You Can Count On Beyond the off-road capabilities, this is still a heavy-duty GMC truck built to work. The Sierra 2500 HD is available with powerful engine options, including a 6,6 L Duramax® diesel that delivers 470 hp and 975 lb-ft of torque, the kind of torque serious towing and hauling demands. It has a max towing capacity of 20,000 lbs for conventional trailering and 21,390 lbs for gooseneck/fifth-wheel trailering. It has a max available payload of 3,524 lbs. Interior Comfort and Technology Capability does not mean you have to give up comfort. The AT4 interior brings a well-appointed cabin with heated and ventilated front seats, power front seats with massaging features, and a modern layout. The13.4-in touchscreen keeps navigation, audio, and vehicle settings easy to manage, and available connectivity features like wireless charging and a built-in Wi-Fi hotspot keep you linked to what's important. GMC Sierra 2500 HD AT4 features extend to driver assistance and safety technologies as well, including available camera systems that make hitching trailers and navigating tight spaces significantly easier.

Full-size trucks used to make you choose: serious capability outside or a genuinely comfortable place to spend a few hours inside. The 2026 GMC Sierra 1500 has largely erased that line. Its cabin can be configured as a straightforward work environment or loaded with leather, large digital displays, advanced trailering technology, and the sort of seats you'd happily settle into for a long interstate haul. For truck shoppers around Portsmouth, NH, the Sierra 1500 interior is a good example of just how far the modern pickup cabin has come. Big Screens Without Forgetting It's a Truck The available digital setup is substantial, with more than 40 diagonal inches of combined driver-focused displays when properly equipped. A 13.4-inch diagonal center touchscreen serves as the main infotainment interface, while available Google built-in compatibility brings supported navigation, voice assistance, and apps into the truck. The clever bit is that GMC hasn't forgotten physical usability in its pursuit of screen acreage. Controls and storage remain positioned for life in a pickup, giving drivers places for the phones, drinks, work gear, and assorted objects that inevitably migrate into a truck cabin. Sierra Seating Goes Well Beyond Basic Comfort Crew Cab models provide generous front headroom and legroom, but the more interesting story is how far GMC lets buyers take the seats themselves. Equipment varies considerably by trim, progressing from more straightforward cloth and leather-appointed configurations to available heated and ventilated seating in upper grades. AT4X and Denali Ultimate can be equipped with 16-way power front seats with massage functionality, a feature that sounds extravagant until you've spent several hours behind the wheel. Denali Ultimate pushes further with full-grain leather seating surfaces and detailed stitching, creating a cabin that is unmistakably upscale without pretending the vehicle outside isn't still a pickup. Each Trim Gives the Cabin a Different Character GMC hasn't simply changed upholstery colors and called them different interiors. Sierra trims develop noticeably different personalities as you move through the range. Elevation keeps things relatively clean and straightforward, while Denali introduces upscale materials and distinctive interior detailing. AT4 takes the cabin in a more rugged direction with its own trim treatment and Kalahari accents, while AT4X adds additional visual distinction befitting the more serious off-road hardware beneath it. Denali Ultimate sits at the other end of the spectrum, using premium materials and additional comfort equipment to create the most lavish Sierra 1500 interior of the bunch. Truck Technology That Earns Its Space Some technology looks impressive in a showroom and then spends most of its life untouched. Sierra's available trailering and camera systems are different because they address jobs pickup owners regularly perform. Up to 14 available camera views can provide additional perspectives around the truck and compatible trailer, helping with hitching, maneuvering, and positioning in confined areas. Available trailering technology can place relevant information within the vehicle's displays, while available Super Cruise® hands-free driver-assistance technology adds another dimension for compatible roads. Super Cruise® is standard on Denali Ultimate and available on Denali, giving long-distance drivers a feature that can become especially appealing after several hours of highway travel. Denali Ultimate Shows How Far a Pickup Cabin Can Go The Denali Ultimate is where GMC makes its strongest case that truck capability and luxury no longer occupy opposite ends of the showroom. Along with its full-grain leather and highly adjustable front seats, it features a 12-speaker Bose® Premium Series audio system with Centerpoint® surround sound and additional upscale cabin detailing. None of this increases payload or makes a trailer lighter, of course, but trucks spend plenty of their lives carrying people instead of lumber. Making those miles more comfortable isn't frivolous when the truck doubles as family transportation, a tow vehicle, and the thing you drive to work every morning. Explore the 2026 GMC Sierra 1500 in Portsmouth, NH The 2026 GMC Sierra 1500 interior can be configured for very different owners, from someone who wants a straightforward truck cabin to a driver looking for Denali Ultimate's leather, massage seating, premium audio, and advanced technology.

Your GMC truck works hard — and so do your brakes. Whether you're hauling a load across town or navigating the roads around Portsmouth, NH, your braking system is one of the most critical safety components on your vehicle. Staying current with GMC brake inspections is one of the simplest ways to protect yourself, your passengers, and everyone else sharing the road with you. more Brake Problems Rarely Announce Themselves Brakes don't fail all at once. They wear down gradually, which means the warning signs can be easy to dismiss until a real problem develops. Skipping regular GMC brake inspections allows small issues — like worn brake pads or low brake fluid — to quietly become larger, more expensive repairs. Brake pads that wear past their safe limit can damage rotors, leading to costly resurfacing or replacement. Catching this kind of wear early keeps repair costs manageable and your truck performing as it should. Common Signs Your GMC Truck's Brakes Need Attention GMC truck safety starts with knowing what to listen and look for. A high-pitched squealing noise when you apply the brakes is often the first sign that your brake pads are wearing thin. Grinding sounds typically indicate the pads are worn through entirely and metal-on-metal contact is occurring. Other warning signs include a soft or spongy brake pedal, pulling to one side when braking, vibration through the steering wheel, or a longer stopping distance than usual. If you notice any of these symptoms, it's time to schedule an inspection right away. How Often Should You Schedule GMC Brake Inspections As a general rule, having your brakes inspected at least once a year is a solid baseline for most drivers. However, how you use your GMC truck matters significantly. If you tow heavy loads, drive in stop-and-go traffic frequently, or put high miles on your vehicle, you may need inspections more often. Many drivers take advantage of routine tire rotations or oil changes to have their brakes checked at the same time. This approach makes it easy to stay consistent without adding extra trips to the service center. What a Professional GMC Brake Inspection Covers A thorough GMC brake inspection goes beyond just glancing at the pads. A certified technician will measure brake pad thickness, examine rotors for wear, scoring, or warping, check brake fluid levels and condition, inspect brake lines and hoses for leaks or damage, and test the overall brake system performance. This comprehensive look gives you a clear picture of your truck's braking health and helps prioritize any repairs that may be needed. GMC truck safety depends on each of these components working together reliably. Your GMC Was Built to Work. Its Brakes Must Keep Up. Regular GMC brake inspections are one of the most straightforward steps you can take to protect your investment and drive with confidence. Don't wait until you notice a problem — staying proactive is always the smarter approach when it comes to GMC truck safety. Holloway GMC in Portsmouth, NH, has a team of certified service professionals ready to help keep your truck in peak condition. Visit Holloway GMC to schedule your brake inspection today.

The 2026 GMC Sierra 1500 has held its own year over year in the half-ton truck segment. It has its own style and still brings the capability too. In a crowded half-ton class, those qualities stick out above the rest. The capability is there, the luxury is there, and together they create something that feels complete. For truck enthusiasts near Portsmouth, that balance goes noticed. Work, weather, distance. This truck can adapt to a lot without asking for too much in return. more Performance That Feels Effortless, Not Forced The Sierra 1500 offers a range of engines, but what stands out is how naturally the power is delivered. The TurboMax™ engine produces 310 hp and 430 lbs. ft. of torque, giving it a strong, usable baseline for everyday work. Step into the available Duramax® 3.0L Turbo-Diesel, and the character shifts toward long-range strength. With a towing capacity up to 13,300 lbs., it carries weight without feeling burdened. Compared to trucks like the Ford F-150® or Ram 1500, the Sierra doesn’t rely on extremes. It delivers a steadier, more composed performance. One that feels suited to both daily driving and heavier demands. Technology That Integrates Cleanly Inside, the Sierra presents its technology with clarity. Large digital displays, over 40 inches combined available, are arranged in a way that feels intentional rather than excessive. Super Cruise® offers hands-free driving on compatible roads, and it does so without drawing unnecessary attention to itself. It simply reduces effort over longer distances. Up to 14 camera views add another layer of usability, especially when towing or navigating tighter spaces. These are features that support the experience rather than complicate it. Interior That Balances Utility and Refinement Authentic wood trim, perforated leather seating, and a clean, horizontal design create an environment that feels considered. Not overly styled, not overly simple. Just resolved. Compared to competitors, which often lean heavily toward either utility or luxury, the Sierra manages to hold both without compromise. If you’ve been weighing comfort against practicality, this is where the Sierra becomes difficult to overlook. Capability That Extends Beyond the Road For those who venture further, the AT4 and AT4X trims bring a different dimension. A factory lift, skid plates, and available Multimatic® DSSV dampers give the truck real off-road credibility. Front and rear electronic locking differentials add a level of control that remains uncommon in the segment. It’s capability that feels engineered, not added on. Against rivals like the Toyota Tundra or Ford F-150® Raptor, the Sierra’s approach is more measured, but no less capable. It’s designed to perform without sacrificing everyday usability. Experience the Sierra 1500 in Portsmouth, NH Understanding a truck like this on paper is one thing. Experiencing how it drives, how it feels, and how it fits into your work, and play, is something else entirely. When you’re ready, visit Holloway GMC and schedule a test drive online.

The 2026 GMC Yukon is essentially a rolling statement of intent. It’s GMC’s way of saying that just because you have a large family doesn't mean you should have to drive something that feels like a city bus. For the folks in Portsmouth, NH, this is a machine that’s as comfortable parked in front of a high-end restaurant as it is navigating a muddy track in the Great North Woods. It is the definitive full-size GMC SUV, blending proper grit with a level of refinement that would make a library feel a bit rowdy. more A Closer Look at the 2026 GMC Yukon The 2026 GMC Yukon is designed to be noticed. It has a bold, commanding grille and signature LED lighting that gives it a proper "get out of my way" presence. But once you step inside, the drama settles into pure sophistication. The cabin is a sanctuary of premium materials, particularly if you opt for the available Obsidian Rush full-grain leather seats. The tech is equally impressive. You get a massive, standard 16.8-inch diagonal Premium GMC Infotainment System touchscreen that handles everything with a flick of a finger, plus an available 15-inch diagonal Head-Up Display that projects your vital stats onto the glass like something out of a fighter jet. With seating for 8, nobody is getting left behind. Whether you're navigating Portsmouth's tighter streets or heading out on a massive road trip, the 122.8 cu. ft. of max cargo space means you can bring the groceries, the camping gear, and probably the kitchen sink too. Performance That Matches Its Presence There’s no point looking this tough if you don't have the hardware to back it up. The 2026 GMC Yukon gives you options. The standard 5.3L V8 engine is a solid workhorse, pushing out 355 hp and 383 lbs. ft. of torque. It’s more than enough for the daily commute or towing a decent-sized boat. If you need more muscle, there’s a 6.2L V8 and a very clever Duramax® 3.0L Turbo-Diesel for those who prioritize range and low-end grunt. The Yukon’s advanced suspension system—including available Magnetic Ride Control—makes sure the ride is smoother than a freshly paved highway, even when the road beneath you is anything but. For Portsmouth winters, the available Active Response 4WD system is a godsend, providing the kind of grip and confidence you need when the snow starts piling up.

The 2026 GMC Acadia approaches family transport with a refreshingly sensible mindset. It is not trying to reinvent the SUV; it is simply trying to do it properly. For families in Portsmouth, NH, that means generous space, technology that actually helps, and performance that feels composed rather than theatrical. In daily use, the Acadia proves itself to be the sort of vehicle that quietly makes life easier. more Space Where It Matters Most One of the Acadia’s greatest strengths is how calmly it handles people and their things. Seating for up to 8 is spread across three rows, with available second-row one-touch folding seats and power-folding third-row seating on higher trims such as Denali. The result is flexibility that works in real situations, not just on a spec sheet. Cargo space reaches up to 97.5 cu. ft. with the rear rows folded, which means sports gear, grocery runs, and weekend luggage fit without negotiation. Materials throughout the cabin feel thoughtfully chosen, balancing durability with comfort so long drives do not feel like a chore. For families leaning toward a more refined experience, the Denali Ultimate trim adds Woodland Mahogany full-leather massaging front seats and a panoramic sunroof that brightens the cabin without overwhelming it. Safety That Feels Reassuring, Not Intrusive Family vehicles need to inspire confidence, and the 2026 Acadia does exactly that with more than 19 standard safety and driver-assistance features. Systems such as Automatic Emergency Braking and Lane Keep Assist with Lane Departure Warning work quietly in the background, supporting the driver rather than competing for attention. Available Super Cruise® hands-free driver assistance technology adds another layer of ease on compatible highways, particularly during longer trips. A comprehensive camera setup, including HD Surround Vision and a Rear Camera Mirror, makes tight parking lots and narrow streets far less stressful. Performance That Fits Family Life Power comes from a Turbocharged 2.5L engine producing 328 hp and 326 lbs. ft. of torque, paired with an 8-speed automatic transmission. The result is smooth, confident acceleration that feels well matched to the Acadia’s size. Drivers who enjoy heading beyond paved roads will appreciate the Traction Select System, which offers up to six drive modes. The AT4-exclusive Terrain Mode adds extra confidence when conditions turn less predictable. With a maximum towing capacity of 5,000 lbs. when properly equipped, the Acadia is equally ready for campers, small boats, or utility trailers.
