Barrington, Illinois truck drivers always come back to GMC pickups for their capability and dependability. With so many model, trim, and engine options, there’s something for everyone—but which one is the best for towing? Whether you're hauling a boat, a horse trailer, or heavy equipment, choosing the right GMC truck is everything. They all are built to handle serious work without sacrificing everyday comfort —but they’re all very different. The 2026 GMC Canyon: Mid s ize & Mighty Not every Illinois driver needs a full-size machine. The 2026 GMC Canyon is a great starting point for drivers who need GMC truck capability but want a more manageable size that’s easy to maneuver around town. With its TurboMax ™ engine delivering Best-in-Class standard torque at 430 lbs.-ft., this truck can tow up to 7,700 lbs. For those who don't need heavy-duty muscle every day, the Canyon is well- rounded— not to mention it’s intensely off-road capable for the more adventurous driver. If you're asking which GMC truck is best for towing lighter loads — campers, small trailers, and recreational equipment, the Canyon fits the bill. The 2026 GMC Sierra 1500: The Sweet Spot For many drivers, the 2026 GMC Sierra 1500 hits the perfect balance between everyday usability and real towing capability of up to 13,300 lbs. It's one of the most popular GMC trucks on the road for that reason, offering a wide range of trims so there’s a comfort level, capability focus, and features to appeal to just about anyone. The Sierra 1500 AT4 trim for instance is for the off-road enthusiast, armed with a 2” lift, off-road suspension, and a long list of rugged enhancements. Th e premium Denali indulges you in heated, ventilated leather seats and exclusive styling. The 2026 GMC Sierra HD: Maximum Towing Power When the question is which GMC truck is best for towing the heaviest loads, the answer is clear: the 2026 GMC Sierra HD. Available in 2500HD and 3500HD configurations, the Sierra HD is engineered for demanding towing and hauling tasks. The 2500HD offers a conventional towing capacity of 20,000 lbs., while the 3500HD amps that up to 36,000 lbs. when equipped with the Turbo-Diesel engine. The Sierra HD i s the go-to choice for contractors, ranchers, and anyone who regularly moves large trailers, 5 th -wheel campers, or commercial equipment. The Sierra HD Denali also brings luxury finishes and premium technology into the cab, so you don't have to sacrifice comfort to get serious capability. Choosing the Right Trim for Your Towing Needs Beyond cho osing between the Canyon, Sierra 1500, and Sierra HD, the trim level you pick also plays a role in your towing experience. O ff-road-focused trims like the AT4 carry heavier equipment to arm them for extremes, and their towing capacity compensates for that. If you frequently tow in challenging conditions, an AT4 could be the right fit. If you want premium features and refinement alongside your truck's capability, a Denali trim delivers both. Thinking about which GMC truck is best for towing in your specific situation will help narrow down your choices quickly.

No matter what you drive—a workhorse Sierra 1500, a family -hauler Yukon, or a versatile Acadia—your brakes are the most critical safety system on your GMC. K nowing when to bring your GMC in for brake service is critical too—if you expect your brakes to do their job, you’ve got to make sure they have the right care. For the drivers of Barrington, Illinois who face all kinds of weather conditions, all kinds of traffic, and go on all kinds of adventures, keeping your brakes in top shape is non-negotiable for safe driving. Why GMC Brake Service Matters Regular GMC brake service is n’t just about passing an inspection — it's about protecting yourself, your passengers, and everyone else on the road. Brake s wear down gradually — sometimes imperceptibly— which means it's easy to miss the early warning signs. The best course of action is to stay proactive with GMC service. That’s what will help you avoid more costly repairs and ensures your vehicle perform s the way it was designed to. GMC trucks and SUVs are built to handle demanding conditions, but that also means your braking system works hard. From stop-and-go traffic to hauling heavy loads, your brakes take on a lot, and routine service helps ensure they're always up to the task. Signs Your GMC Needs Brake Service One of the most common signs your GMC vehicle needs brake service is a squealing or grinding noise when you apply the brakes. This often means your brake pads are worn and need to be replaced. That grinding is metal-on-metal contact, and indicates your pads may be worn completely asway. Ignoring this sound can lead to rotor damage, which is a more expensive fix. Other signs your GMC needs brake service include a soft or spongy brake pedal, vibration when braking, or the vehicle pulling to one side when you slow down. And then there’s the dreaded brake warning light. When that comes on, it’s a clear signal to schedule service as soon as possible. Trust your instincts — if something feels off, it's worth having a technician take a look. What to Expect During a Brake Inspection During a brake inspection, a C ertified technician will examine your brake pads, rotors, calipers, and brake fluid. They'll check pad thickness, look for uneven wear, and assess whether any components need replacement. This process is straightforward and gives you a clear picture of your brake system's health. GMC Certified Service technicians are factory-trained to work specifically on GMC vehicles. That expertise means they know exactly what to look for and how to keep your truck or SUV performing at its best. It’s not the same as having a general mechanic look at your vehicle, and using Certified Service means you’ll get original equipment manufacturer (OEM) parts. Drivers in Barrington can count on an elevated level of care and attention to detail at every visit to a Certified Service center. How Often Should You Schedule GMC Brake Service? There's no one-size-fits-all answer, but most experts recommend having your brakes inspected at least once a year or every 12,000 miles. If you frequently tow trailers, drive o n hilly terrain, or spend a lot of time in heavy traffic, you may need to schedule brake service more often. Your vehicle's owner's manual is a great starting point for understanding the recommended maintenance intervals for your specific GMC model. When in doubt, ask a C ertified technician — they can assess your driving habits and recommend a service schedule that fits your needs. Visit Marquardt of Barrington GMC for Brake Service When it comes to GMC brake service, it pays to work with people who know your vehicle inside and out.

The 2026 GMC Sierra 1500 is one of the most versatile light-duty pickup trucks on the market today. No matte r if you're hauling equipment during the week or heading out on a weekend adventure, the Sierra 1500 can handle whatever you throw at it. If you're exploring your options near Barrington, IL, this guide breaks down everything you need to know before you buy. What Makes the 2026 GMC Sierra 1500 Stand Out The 2026 Sierra 1500 earns its reputation through a combination of advanced engineering and stylish design. From work-ready base configurations to the premium Denali trim, the Sierra 1500 appeals to a wide range of truck buyers. This is also a truck that benefits from current Truck Month offers, including 0% APR for five years for well-qualified buyers who finance through GM Financial, plus no monthly payments until next year. You must take delivery by 9/30/26. Trim Levels: Finding the Right Fit The Sierra 1500 lineup starts with the Pro and includes the SLE, Elevation, SLT, AT4, AT4X, Denali, and Denali Ultimate. The AT4 trim is designed for drivers who want off-road capability alongside everyday comfort. It comes equipped with a standard 2-in factory lift, off-road suspension, Rancho monotube shocks, a two-speed Autotrac transfer case, and underbody skid plates. The standard Duramax ® 3.0L Turbo-Diesel produces 305 hp and 495 lb -ft of torque. The Sierra 1500 Denali takes the experience to another level, offering a luxurious cabin, sophisticated styling, and a host of premium features that make it one of the most stylish trucks in its class. The Denali includes a standard 5.3L V8 with a 10-speed automatic transmission, while the available Duramax ® 3.0L Turbo-Diesel adds another powertrain option. Features That Work as Hard as You Do The 2026 Sierra 1500 comes equipped with a 13.4- in multicolor touchscreen, a 12.3-in Driver Information Center, and available Super Cruise ® hands-free driver assistance technology. On the capability side, the available ProGrade Trailering System provides integrated tools for the hitching and towing process, while up to 14 available camera views help drivers maneuver the truck and trailer. Properly equipped, the 2026 Sierra 1500 can tow up to 13,300 lb s. The available MultiPro Tailgate also adds flexibility to the bed, offering multiple configurations to make loading and unloading easier. The GMC MultiPro Tailgate is an available six-function tailgate. AT4 and Denali: Purpose-Built Performance For drivers who want more from their Sierra 1500, the AT4 and Denali trims represent two very different but equally compelling paths. The AT4 is built for those who want off-road capability, with a standard 2-in factory lift, off-road suspension, Rancho ® monotube shocks, a two-speed Autotrac transfer case, and underbody skid plates. The Denali, on the other hand, is crafted for those who want the most stylish driving experience in the Sierra lineup. The Denali offers premium interior materials and available driver assistance technology, including available Super Cruise ®.

The 2026 GMC Acadia has grown into a sort of midsize SUV that can take on jobs once reserved for something larger, without becoming an enormous thing to thread through a car park. There are 3 rows, seating for up to 8, 97.5 cu. ft. of maximum cargo space, and a turbocharged engine with enough torque to tow 5,000 lbs. when properly equipped. For drivers around Barrington, IL, the Acadia range also makes sensible distinctions between its trims, from the straightforward Elevation to the more rugged AT4 and increasingly well-equipped Denali models. One Engine, and It's a Strong One Every 2026 Acadia uses a T urbocharged 2.5L 4-cylinder producing 328 hp and 326 lbs. ft. of torque, paired with an 8-speed automatic transmission. That simplifies the buying process because moving through the trim lineup doesn't require sacrificing power to get the equipment you want. Elevation models offer FWD or available AWD, while AT4 uses an Active Torque Control AWD system designed to distribute torque between the rear wheels when conditions demand it. Properly equipped, the Acadia can tow up to 5,000 lbs., enough for many small campers, boats, and utility trailers without moving into a truck-based SUV. Elevation, AT4, or Denali Depends on Where You're Going Elevation establishes a surprisingly substantial baseline with the 328 hp engine, 15-inch GMC Infotainment System, Google built-in compatibility, and a Bose® 12-speaker audio system. AT4 is the one for drivers who expect to leave maintained pavement, adding standard AWD, an off-road-tuned suspension, hill descent control, and 18-inch wheels fitted with all-terrain tires. Denali shifts the emphasis toward cabin appointments with leather seating surfaces, heated and ventilated front seats, and distinctive exterior detailing, while Denali Ultimate pushes further with premium materials and standard Super Cruise®. The differences are useful rather than decorative: Elevation covers general family duty, AT4 adds hardware for poor surfaces, and the Denali models concentrate on technology and interior equipment. A 15-Inch Screen Without the Usual Button Purge The standard 15-inch diagonal GMC Infotainment System gives the Acadia a large portrait-oriented touchscreen with Google built-in, wireless Apple CarPlay ® and Android Auto™ compatibility. Importantly, GMC hasn't used the screen as an excuse to make every basic function disappear into a digital maze. An available 8-inch Head-Up Display puts speed, navigation, and other information in the driver's sightline, while available Super Cruise® adds hands-free driver assistance on compatible roads. For Barrington drivers spending time on I-90 or heading toward Chicago, that technology has considerably more practical value than another illuminated badge. Three Rows with Proper Cargo Space Behind Them Elevation can seat up to 8 passengers, while AT4, Denali, and Denali Ultimate configurations accommodate up to 7. Fold the rear seating and maximum cargo volume reaches 97.5 cu. ft., giving the Acadia enough room for luggage, sports equipment, furniture, or the consequences of walking into a home-improvement store without a firm plan. The Traction Select System provides multiple available drive modes, and the standard Trailering Package supports that 5,000 lb. maximum tow rating when the vehicle is properly configured. Driver Assistance Comes Standard in Quantity More than 19 safety and driver-assistance technologies are standard across the 2026 Acadia lineup. These include Enhanced Automatic Emergency Braking, Front Pedestrian and Bicyclist Braking, Lane Keep Assist with Lane Departure Warning, Blind Zone Steering Assist, Adaptive Cruise Control, and Rear Cross Traffic Braking. Available HD Surround Vision provides multiple camera views around the SUV, particularly useful when maneuvering a 3-row vehicle through tighter parking spaces. Teen Driver technology also gives families another way to monitor and encourage safer driving habits when a younger driver gets the keys. Find the Acadia That Fits Barrington The 2026 GMC Acadia makes its case with numbers that mean something: 328 hp, 326 lbs. ft. of torque, up to 8 seats, 97.5 cu. ft. of cargo room, a 15-inch touchscreen, and up to 5,000 lbs. of towing capacity. Visit Marquardt of Barrington GMC to compare Elevation, AT4, Denali, and Denali Ultimate models, explore available Acadia inventory, and schedule a test drive online.

The 2026 GMC HUMMER EV is difficult to fit into a conventional category. It's available as both a Pickup and an SUV, uses an all-electric platform, and combines enormous power with hardware designed for serious off-road driving. Four-wheel steering, available CrabWalk ™, and UltraVision ® camera technology aren't there simply to make the specification sheet longer; they change what a vehicle of this size can do. For drivers considering a GMC HUMMER EV around Barrington, IL, the choice between SUV and Pickup ultimately comes down to how that capability needs to fit into everyday life. The Numbers Are Enormous, but the Hardware Is More Interesting The 2026 HUMMER EV Pickup 3X with the 24-module battery pack can produce up to 1,160 hp and a GM-estimated 13,000 lbs. ft. of motor torque, while the HUMMER EV SUV 3X offers up to 830 hp and a GM-estimated 11,500 lbs. ft. of motor torque. Those motor-torque figures aren't directly comparable with conventional engine torque measured at the crankshaft, but they illustrate the scale of the electric propulsion systems involved. More interesting is how GMC uses that performance. Available four-wheel steering can turn the rear wheels to improve maneuverability, while CrabWalk ™ allows the vehicle to move diagonally at low speeds to negotiate certain tight off-road situations. Range Makes Both Versions Easier to Use The HUMMER EV Pickup 3X with the 24-module battery pack offers up to 363 miles of GM-estimated range, while the SUV can provide up to 319 miles depending on configuration. Those figures give Barrington drivers useful flexibility for commuting, highway travel, and trips well beyond the Chicago suburbs. Both models support high-power 800V DC fast charging on compatible equipment, allowing owners to add useful range during a charging stop rather than relying exclusively on overnight charging. For an EV this large and capable, the combination of substantial battery range and rapid-charging capability is an important part of making the vehicle usable beyond short local journeys. The SUV and Pickup Solve Different Problems The Pickup gives owners a conventional cargo bed, making it the natural choice for hauling equipment and bulky outdoor gear. The HUMMER EV SUV trades that open bed for an enclosed rear cargo area and a shorter overall footprint, while providing seating for up to 5. The SUV can also tow up to 10,000 lbs. when properly configured. Both retain the basic HUMMER EV character, so choosing between them isn't about picking the capable one. It's deciding where you want the cargo, how much enclosed passenger and storage space you need, and how the vehicle will be used around Barrington during the rest of the week. Cameras Become Off-Road Equipment A 13.4-inch diagonal center touchscreen anchors the cabin, accompanied by a digital Driver Information Center. Available UltraVision ® provides up to 17 camera views, including available underbody views that can help the driver see obstacles that would otherwise disappear beneath the vehicle. That's useful technology in a vehicle built to travel across uneven terrain, where knowing exactly where a tire or rock is positioned can be more valuable than another entertainment feature. Available Super Cruise® adds hands-free driver assistance on compatible roads, bringing a very different kind of technology into play once the HUMMER EV returns to the highway. Carbon Fiber Editions Turn Things Up Further For 2026, available Carbon Fiber Editions give both HUMMER EV body styles a more distinctive appearance. The SUV Carbon Fiber Edition combines an exclusive Magnus Gray Matte exterior with a Velocity Ember interior, 22-inch Black Carbon Fiber wheels, and additional carbon-fiber-themed details. It's an interesting contrast with the HUMMER EV's off-road engineering: sophisticated materials and finishes applied to a vehicle that can use CrabWalk ™ to negotiate its way around rocks and other obstacles. Explore the 2026 GMC HUMMER EV in Barrington The HUMMER EV isn't simply an electric version of an existing GMC truck or SUV. Its electric architecture supports up to 1,160 hp in the Pickup, while four-wheel steering, available CrabWalk ™, UltraVision ®, and substantial driving range give both versions their own character. Drivers searching for a GMC HUMMER EV near Barrington, IL, can visit Marquardt of Barrington GMC to browse the entire new HUMMER EV inventory, compare SUV and Pickup models, explore GMC EV financing options, or learn more about EV service and charging. Once you've decided which body style fits your plans, schedule a test drive online and experience the HUMMER EV from behind the wheel.

The 2026 GMC Terrain Is Worth the Trip

The 2026 GMC HUMMER EV belongs in its own category. It's enormous, unapologetically bold, and capable of doing things that seem to ignore the laws of physics. Yet beneath all that bravado is something remarkably well engineered. The HUMMER EV isn't simply about headline numbers—although it has plenty of those. It's about proving that electrification doesn't have to dilute capability. You can choose the Pickup or the SUV; either way you're getting a vehicle that feels unlike anything else on the road. Two Body Styles, One Remarkable Idea The beauty of the HUMMER EV lineup is that GMC never asks buyers to compromise on capability. The Pickup is the adventurer's tool. It combines immense off-road confidence with the practicality of an open cargo bed, making it just as comfortable hauling equipment as it is climbing over terrain most vehicles would rather avoid. The SUV takes that same engineering philosophy and wraps it in a package that's a little easier to live with every day. More passenger-focused, equally adventurous, and every bit as distinctive, it brings HUMMER EV capability to drivers who want maximum versatility without giving up interior space. Different shapes, certainly. Different personalities, perhaps. But unmistakably cut from the same cloth. Performance That Changes Expectations This is where the conversation usually changes. The HUMMER EV Pickup delivers a staggering best-in-class 1,160 hp and a best-in-class 13,000 lbs. ft. of torque when equipped with the available 24-Module Battery Pack and Watts to Freedom. That's enough to launch this remarkably substantial truck from 0-60 mph in approximately 2.8 seconds—figures that would have seemed laughably unrealistic for a pickup not all that long ago. The HUMMER EV SUV is hardly left behind. With up to 830 hp and a best-in-class 11,500 lbs. ft. of torque, it can reach 60 mph in approximately 3.5 seconds using Watts to Freedom. They're numbers that demand attention. More importantly, they're backed by genuine engineering rather than empty marketing. Electric Range Without the Anxiety Performance is only part of the story. The available 24-Module Battery Pack allows the HUMMER EV Pickup to travel up to a GM-estimated 363 miles on a full charge, while the SUV delivers up to a GM-estimated 319 miles. Those figures transform the ownership experience. Weekend adventures become easier to plan, long-distance travel feels far less restrictive, and daily commuting barely registers on the battery gauge. It's the kind of confidence that encourages owners to stop thinking about range altogether and simply enjoy the drive. Technology That Expands Capability The HUMMER EV's technology isn't there to impress people in a showroom. It's there because it genuinely makes the vehicle more capable. Available Super Cruise® brings hands-free driving assistance to compatible roads, reducing fatigue on long journeys. Multiple selectable drive modes—including Off-Road, Terrain, Tow/Haul, Normal, and My Mode—allow the vehicle to adapt its personality to the terrain beneath its tires. Inside, the cabin balances rugged functionality with premium finishes in a way that feels entirely appropriate. It's durable where it needs to be, refined where you want it to be, and unmistakably modern throughout. For buyers looking for something even more distinctive, the available Carbon Fiber Edition adds an extra layer of exclusivity to an already unforgettable vehicle. A New Definition of Capability The 2026 GMC HUMMER EV isn't trying to replace traditional trucks and SUVs by copying them. It's creating an entirely new category—one where extraordinary acceleration, serious off-road capability, advanced technology, and everyday practicality coexist in a single vehicle. That's a rare achievement, regardless of how it's powered. See the 2026 GMC HUMMER EV at Marquardt of Barrington GMC The 2026 GMC HUMMER EV Pickup and SUV prove that electric vehicles can be every bit as capable, adventurous, and exciting as their gasoline-powered counterparts—while bringing entirely new possibilities to the road and the trail. Visit us in Barrington to explore both HUMMER EV body styles, compare available configurations, or schedule a test drive online to experience firsthand why this is one of the most ambitious electric vehicles ever built.

The best family SUVs aren't the ones with the flashiest features. They're the ones that make life easier every single day. The school run, the grocery haul, the weekend getaway, the road trip that somehow requires three coolers and half the garage—they're all part of the job description. Insert the 2026 GMC Acadia in Barrington. Four Trims, Four Different Personalities One of the Acadia's strengths is that every trim feels like it was built with a different buyer in mind. The Elevation gives you just about everything most families could ask for. A massive 15-inch diagonal Premium GMC Infotainment System, a Bose® Premium 12-speaker audio system, and more than 19 standard safety and driver assistance features make it feel anything but entry level. The AT4 takes things in a more adventurous direction. All-terrain tires, a lifted suspension, steel skid plates, and off-road tuning give it the confidence to venture beyond paved roads without giving up everyday comfort. If luxury is higher on your list, the Denali delivers leather-appointed seating, heated and ventilated front seats, and striking 20-inch machined aluminum wheels that give the Acadia a more upscale presence. At the top sits the Denali Ultimate. It adds features that genuinely elevate the driving experience, including hands-free Super Cruise®, massaging front seats, a panoramic sunroof, and a Bose® Performance Series 16-speaker audio system. Turbocharged Power That Gets the Job Done Every 2026 Acadia comes equipped with the same 2.5L Turbocharged engine paired with an 8-speed automatic transmission. With 328 hp and 326 lbs. ft. of torque on tap, there's plenty of muscle for merging onto busy highways, climbing steep grades, or carrying a full load of passengers and cargo. The power delivery feels smooth and confident, exactly what you'd want in an SUV that's expected to do a little bit of everything. Need to tow? Properly equipped with the available Trailering Package, the Acadia can pull up to 5,000 lbs., giving owners the flexibility to bring along a camper, fishing boat, or utility trailer for weekend adventures. The available Traction Select System, with up to six drive modes, also helps tailor the SUV to changing weather and road conditions throughout the year. Technology That Works with You The standard 15-inch diagonal infotainment display serves as the centerpiece of the cabin, with available Google built-in providing access to Google Maps, Google Assistant, and compatible apps without needing to rely entirely on your phone. An available Head-Up Display projects key driving information onto the windshield, while up to nine available camera views—including HD Surround Vision—make parking, towing, and maneuvering in tight spaces noticeably easier. Confidence Comes Standard Every Acadia includes an impressive list of standard driver assistance features. Enhanced Automatic Emergency Braking, Front Pedestrian and Bicyclist Braking, Lane Keep Assist with Lane Departure Warning, Blind Zone Steering Assist, Adaptive Cruise Control, and Forward Collision Alert all work together to help reduce stress behind the wheel.

Electric trucks have reached an interesting point. They are no longer simply alternatives to traditional pickups; they are becoming compelling choices in their own right. The 2026 GMC Sierra EV proves exactly why. It combines the capability expected of a full-size truck with advanced electric technology, impressive range, and innovative features that make daily driving every bit as rewarding as weekend adventures. For drivers around Barrington, Lake Zurich, Palatine, and the greater Northwest Chicago suburbs, the Sierra EV is redefining what a modern pickup can be. Three Trims, Three Different Missions The Sierra EV lineup is refreshingly straightforward, with Elevation, AT4, and Denali trims designed around different priorities rather than simply adding more equipment as you move up the range. The Elevation establishes a strong foundation with a power-open eTrunk offering 11 cu. ft. of lockable front storage, heated front seats, a 10-way power driver's seat, and a best-in-class standard output of 605 hp. Buyers can choose the Standard Range battery with an EPA-estimated range of up to 283 miles or step up to the available Extended Range battery with an EPA-estimated range of up to 410 miles. Drivers who regularly venture beyond the pavement will appreciate what the AT4 brings to the lineup. Thirty-five-inch all-terrain tires, approximately 2 inches of additional ground clearance, red recovery hooks, standard 4-Wheel Steer with CrabWalk™, and standard Super Cruise® give it a distinctly adventurous personality. Depending on battery configuration, the AT4 produces up to 725 hp and 775 lbs. ft. of torque while offering a maximum towing capacity of up to 12,300 lbs. when properly equipped. The Denali approaches the Sierra EV from another direction. Premium materials, distinctive 22-inch wheels with Ultrabright machining, and laser-etched Denali badging create a more refined atmosphere, while available Air Ride Adaptive Suspension and an available panoramic fixed glass roof elevate the driving experience even further. Equipped with the Max Range battery, the Denali produces up to 760 hp and 785 lbs. ft. of torque with a GM-estimated range of up to 478 miles. Range That Expands Your Horizons Range anxiety becomes much less of a conversation when a truck is capable of travelling this far between charges. The Sierra EV offers battery choices designed around different driving needs, from the Standard Range battery to the available Extended Range and Max Range configurations. Drivers covering longer distances across northern Illinois or commuting throughout the Chicagoland area will appreciate the flexibility each option provides. Charging has also become considerably more convenient. AT4 and Denali models support available 800V public DC fast charging, while Elevation supports available 670V public DC fast charging. Equipped with the Max Range Battery Pack, compatible fast chargers can add up to 120 miles of driving range in approximately 10 minutes. Technology That Works as Hard as the Truck The Sierra EV's cabin feels modern without becoming overwhelming. Every model includes a 16.8-inch premium GMC infotainment touchscreen with Google built-in, complemented by an 11-inch Driver Information Center that keeps key vehicle information directly within the driver's line of sight. AT4 and Denali models add a 14-inch multicolor Head-Up Display, while Super Cruise® is standard on both trims and available on Elevation. Up to 14 available camera views make maneuvering, trailering, and parking considerably easier, particularly for drivers who regularly put their truck to work. Capability Backed by Confidence Every Sierra EV includes more than 16 standard safety and driver-assistance features, including Intersection Automatic Emergency Braking, Side Bicyclist Alert, and available OnStar® Automatic Crash Response. Together, these systems help support drivers throughout daily commuting, weekend travel, and demanding workdays alike.

Compact SUVs focus on getting the essentials right. That's precisely the approach GMC has taken with the 2026 Terrain. It's thoughtfully engineered, pleasingly developed, and versatile enough to handle everything from weekday commutes to spontaneous weekend escapes. For drivers around Barrington, Lake Zurich, Inverness, and the Northwest suburbs, the latest Terrain offers plenty to appreciate. One SUV, Three Distinct Characters The Terrain lineup begins with the Elevation, but that's hardly where the story ends. Elevation establishes a strong foundation with heated front seats, a heated steering wheel, and more than 16 standard safety and driver-assistance features. It's a trim that feels complete from the outset, offering everyday comfort without unnecessary complexity. AT4 takes a more adventurous path. A lifted suspension, front skid plate with a steel underbody shield, red recovery hooks, 17-inch Dark Machined aluminum wheels wrapped in all-terrain tires, and an exclusive Terrain drive mode prepare it for gravel roads, muddy trails, and the sort of routes that don't always appear on a navigation screen. Then comes the Denali, bringing a more polished interpretation of the Terrain. Its signature Galvano chrome grille, animated lighting, heated and ventilated front seats, heated rear outboard seats, and 19-inch Midnight Silver machined-face aluminum wheels create an SUV that feels every bit as premium as its badge suggests. If you're comparing GMC SUVs near Barrington, the Terrain offers a trim for almost every driving style. Technology That Feels Like Second Nature The best technology rarely asks for your attention. It simply works. Every 2026 Terrain includes a 15-inch Premium GMC Infotainment System touchscreen paired with an 11-inch Driver Information Center. Google built-in allows drivers to access navigation, voice assistance, and connected services directly through the vehicle, creating an experience that feels intuitive from the first drive. Instead of adding complexity, the system helps simplify everyday travel, keeping important information exactly where you expect it to be. Designed Around Everyday Practicality Compact on the outside doesn't mean compromised inside. The Terrain seats up to 5 while offering a flexible cargo area that expands to as much as 63.5 cu. ft. with the rear seats folded. A 60/40 split-folding rear bench makes it easy to balance passengers and cargo, while underfloor storage helps keep smaller items tucked neatly away. Available features such as a panoramic sunroof and an AutoSense power liftgate add thoughtful touches that make daily errands and weekend travel noticeably more convenient. Capability for Roads You Didn't Plan On Every Terrain is powered by a 1.5L Turbocharged 4-cylinder engine producing 175 hp, paired with an 8-speed automatic transmission. Available AWD provides additional confidence when northern Illinois weather becomes unpredictable, while selectable drive modes, including Normal, Snow, Off-Road, and Tow/Haul, allow the Terrain to adapt to changing conditions with ease. Properly equipped with the available Trailering Package, it can tow up to 1,500 lbs., giving owners extra flexibility for small trailers, recreational gear, or weekend projects. Confidence Built into Every Journey Safety has become one of the Terrain's strongest attributes. Standard features include Forward Collision Alert, Front Pedestrian and Bicyclist Braking, Blind Zone Steering Assist, Rear Cross Traffic Braking, HD Rear Vision Camera, and IntelliBeam®. Drivers can also choose available technologies such as HD Surround Vision and a Rear Camera Mirror for additional visibility in busy parking lots and tighter spaces.

If you own a GMC truck or SUV, keeping up with your oil change schedule is one of the simplest and most effective ways to protect your investment. If you're driving a Sierra 1500 through the suburbs or hauling gear in a Yukon, routine oil changes keep your engine running cleanly and efficiently. For drivers in Barrington, IL, staying on top of oil changes can make a real difference in the long-term health of your vehicle. Why Regular Oil Changes Matter for Your GMC Your engine oil does more than just lubricate moving parts. It helps reduce heat buildup, prevents corrosion, and keeps contaminants from accumulating inside the engine. Over time, oil breaks down and becomes less effective. Skipping or delaying your oil change allows old, degraded oil to circulate through the engine, which can lead to increased wear and, eventually, costly repairs. Routine oil changes for a GMC are a small investment that pays off in a big way. Staying consistent with your service intervals helps protect your engine's longevity and maintains the kind of performance GMC builds into every vehicle. How Often Should You Change the Oil in a GMC? The answer depends on a few factors, including the model you drive, the type of oil your vehicle requires, and your typical driving habits. Many newer GMC vehicles are equipped with an Oil Life Monitoring system, which tracks driving conditions and engine load to let you know when it's actually time for a change — rather than relying on a fixed mileage interval alone. As a general guideline, vehicles using full synthetic oil often go longer between oil changes compared to those using conventional oil. Your owner's manual is the best source for the manufacturer's recommended interval for your specific model and engine configuration. Conventional vs. Synthetic Oil: Which Does Your GMC Need? Not all engine oil is created equal and using the right type is important. Many newer GMC models — including the Sierra 1500, Sierra HD, and Yukon — recommend full synthetic motor oil to help deliver optimal protection across a wide range of temperatures and driving conditions. Conventional oil may be specified for some older or base-trim models, while a synthetic blend can be a middle-ground option in certain cases. When in doubt, refer to your owner's manual or consult with a certified service technician who is familiar with your vehicle's requirements. Using the correct oil viscosity and specification ensures your engine stays properly protected between routine oil changes for your GMC. What to Expect During a Professional Oil Change Service When you bring your GMC in for an oil change, the process typically involves draining the old engine oil, replacing the oil filter, and refilling the engine with fresh oil that meets your vehicle's specifications. A technician will usually inspect the oil drain plug and filter housing for any signs of leakage as well. Many service visits also include a multi-point inspection, which can flag other items that may need attention — things like tire pressure, fluid levels, or brake condition. This is a convenient way to stay ahead of potential issues while you're already in for your oil change service. Signs It Might Be Time for an Oil Change Your GMC's Oil Life Monitoring system will alert you when a service is due, but there are other signs worth paying attention to between reminders. Dark or gritty-looking oil on the dipstick, a slight burning smell coming from the engine bay, or a louder-than-usual engine note can all indicate that your oil is past due for a change. If you notice the oil pressure warning light on your dashboard, don’t ignore it, have your vehicle inspected as soon as possible. Routine oil changes for a GMC help prevent these warning signs from becoming serious problems in the first place. Schedule Your GMC Oil Change at Marquardt of Barrington A routine oil change is one of the best things you can do for your GMC. It protects the engine and helps maintain performance. Don't wait for a warning light to remind you — staying proactive with your oil change schedule is the smartest approach for any GMC owner.
