Test Drive the 2026 Sierra 1500 in Hot Springs

Schedule a Test Drive View Sierra 1500 Inventory Value Your Trade Most Sierra 1500 test drives run fifteen minutes on a straight four-lane and tell the buyer almost nothing. The truck is quiet, the seat is comfortable, and everybody goes home. Then the new owner finds out in month two that the bed is nine inches shorter than the one they needed, or that the standard-bed Crew Cab does not fit the garage the way they assumed it would. A good test drive is a series of specific checks, and around here the roads to run them on are already outside our door. We have been selling trucks at 4573 Central Ave since 1967, and this is the route and the checklist we walk buyers through. If you want the full spec picture before you drive, start with the 2026 Sierra 1500 research hub — everything below assumes you are past the reading stage and ready to get behind the wheel. Before you show up: narrow it to two trims Eight trims span the 2026 Sierra 1500, from the Pro at $38,300 to the Denali Ultimate at $84,400. Driving all eight is a wasted Saturday. Driving two well-chosen ones tells you everything. The fastest way to narrow the field is by engine, because that is what you feel. The 2.7L TurboMax makes 310 hp and 430 lb-ft and comes standard on Pro, SLE and Elevation. The 5.3L V8 is 355 hp and 383 lb-ft and is standard from SLT up. The 6.2L V8 steps to 420 hp and 460 lb-ft. And the Duramax 3.0L Turbo-Diesel makes 305 hp with 495 lb-ft — the torque number that matters if you tow. Our trim-by-trim comparison lays out which engines pair with which trims and what each one includes. Call ahead with the two you want. We will have both pulled up front and warmed instead of you standing in the lot while somebody hunts for keys. The first ten minutes: low-speed manners on Central Avenue Start where trucks actually struggle. Head north on Central Avenue toward the bathhouse district, where the lanes narrow, the parking is angled, and there is always a delivery van half in the road. This is the single most useful stretch of pavement for a truck shopper in the county. What to check: how tight the turning circle really is, how much of the hood you cannot see, and whether the camera views resolve fast enough to be useful rather than decorative. Try one parallel park. Try one backing maneuver with someone walking behind you. This is also where cab and bed choice stops being an abstraction. A Crew Cab with the short bed is 231.92 inches long; step up to the standard bed and it grows to 242.45 inches on a longer wheelbase, which widens the turning circle noticeably. Both are excellent trucks. They are not the same truck in a parking garage. The cab and bed configuration guide breaks down which combinations exist on which trims, and it is worth a look before you commit. The four-lane running east toward the interstate carries commuter traffic that stacks up fast at the county line, so the difference between a truck that parks easily and one that doesn't shows up every weekday. Then open it up toward Benton Get the truck to highway speed and leave it there for ten minutes. Highway manners are where the engines separate. Listen for how often the transmission hunts on rolling grades — the TurboMax runs an 8-speed, everything else runs a 10-speed. Notice the wind noise at seventy. Check whether the seat still feels right twenty minutes in, because that is the honest test, not the showroom impression. If the truck has Super Cruise, this is the stretch to try it; it is standard on Denali Ultimate and available on Denali. Numbers for the details you notice on this leg — fuel economy by engine, exact dimensions, the driver-assistance breakdown — are all in the full technical specifications. Drive first, look them up after; the order matters. Take the grade north on Highway 7 Run north on Highway 7 for a few miles and let the truck climb. The grades out this direction are short but steep, and they load an engine in a way flat pavement never does. What you are feeling for: whether the truck downshifts early and holds it, or hunts between gears under load. The Duramax pulls from low in the rev range and stays settled on a climb. The 6.2L wants revs and rewards them. Neither is better in the abstract — they are two different driving characters, and ten minutes on a real grade tells you which one you want to live with. If a trailer is in your future, this is the moment to ask about the hitch. Bring your trailer specs, or the tongue weight if you know it, and we can talk through what your build actually needs. The towing capacity guide covers ratings by cab, bed and engine, including what the Max Trailering Package changes. The cab test almost everyone skips Before you head back, park it and get in the back seat. Actually sit there. Crew Cab second-row legroom is 43.40 inches, which is more than a lot of midsize sedans give you up front. Double Cab is 35.24 inches — fine for kids and short trips, tighter for three adults headed to Lake Hamilton for the day. If car seats are part of your life, bring one and install it in the lot. It takes four minutes and it has changed more buying decisions than any spec sheet. Same idea in the bed. Width between the wheelhousings is 50.63 inches, which means a four-foot sheet of plywood needs the tailgate down or an angle. If you haul something specific and regular, bring it, or bring its measurements. The MultiPro Tailgate is standard from SLT up and worth opening all six ways while you are standing there. Ask the ownership questions while you are here The drive answers how the truck feels. It does not answer what owning it costs, and that is the half most buyers forget to ask about until the first service light. Worth asking before you sign: what the oil change interval is for the engine you picked (it differs between the gas engines and the Duramax), what the first-year scheduled maintenance visit covers, and what the warranty runs on the powertrain. Our maintenance and reliability guide has the intervals and warranty terms in one place, and our service department is the same building you bought the truck in — which matters more over a ten-year ownership run than most people weigh at signing. If you are cross-shopping, say so. We would rather you drive the Sierra 1500 back to back against the truck you are actually considering than wonder later. We have written up how it lines up against the Ford F-150 and the Ram 1500, spec for spec. Which Sierra 1500 should you actually drive? Pick the two that match how you will use the truck, and the drive will sort it out: You tow a boat or a trailer most weekends: drive an SLE or SLT with the Duramax, and drive it on the Highway 7 grade. The 495 lb-ft is the whole argument. The truck is a daily driver that hauls occasionally: drive an SLE or Elevation with the 2.7L TurboMax in Crew Cab short bed. Run the Central Avenue leg twice. You need it to work — materials, jobsites, real payload: drive a Pro or SLE Double Cab with the standard bed. Bring what you haul. You want the nice one and you drive a lot of highway: drive a Denali or Denali Ultimate and spend the whole highway leg on Super Cruise. Still deciding between two trims: drive them back to back the same afternoon, same route. Comparing memories a week apart does not work. More questions before you come in? The 2026 Sierra 1500 FAQ page covers what buyers ask us most. Book the drive at Allen Tillery Buick GMC We are family-owned, we have been at this since 1967, and we would rather you take a long test drive and buy the right truck than a short one and buy the wrong one. Bring your trailer specs, a car seat, a tape measure — whatever your version of the truck actually has to do. Tell us the two trims you want waiting and we will have them ready. Buyers come to us from Benton, Malvern and Hot Springs Village, and Oaklawn season weekends fill up fast, so a heads-up helps.

Is the 2026 GMC Canyon Big Enough for a Family?

CTA ROW (DealerOn convention: body opens with the CTA row) Shop Canyon Inventory Sit In One This Week Value Your Trade BREADCRUMB (blog: 2 levels) Home› Blog› Is the Canyon Big Enough for a Family? Published July 24, 2026 · Allen Tillery Buick GMC · 4573 Central Ave, Hot Springs, AR 71913 · (501) 881-4160 ===================== AI / QUICK ANSWER SUMMARY ===================== Quick answer Yes, for most families with kids. Every 2026 GMC Canyon is a five-seat crew cab with four full doors, 45.2 in. of front legroom and 34.7 in. in the second row. That back seat handles car seats and school-age kids comfortably. It gets tight with three adults on a long drive, and there is no third row, so a bigger family needs a different vehicle. Car seats and kids under about 12: the Canyon works well. Two adults in back regularly: workable for short trips, tight for long ones. Six or more people, or a third row: look at a three-row SUV instead. Garage fit: 213.2 in. long and 79.8 in. tall, so it parks like a large SUV, not a full-size truck. ===================== INTRO ===================== This is the question that decides the sale more often than towing or horsepower does. A buyer wants the truck, the truck makes sense for the weekend, and then somebody asks whether the kids actually fit in the back. If the answer is no, the whole plan changes. So here is a straight walk through the Canyon's real interior and exterior numbers, what they mean with a car seat installed, and where a truck stops being the right call for a growing family. The four-lane running east toward the interstate carries commuter traffic that stacks up fast at the county line, so the difference between a vehicle that parks easily and one that doesn't shows up every weekday, not just on a road trip. ===================== TOC ===================== On this page What the back seat is actually like Where the gear goes Living with it Monday through Friday When a Canyon is the wrong answer Which trim makes the most sense for a family Questions parents ask us ===================== H2 1 ===================== What the back seat is actually like There is one Canyon body: a crew cab with four full-size doors, seating up to 5. There is no extended cab and no two-door version, so every Canyon on our lot has a real back seat with real doors, which matters more for car-seat duty than any single measurement. The front row has 40.3 in. of headroom and 45.2 in. of legroom, which is generous by any standard. The second row has 34.7 in. of legroom. To put that in context, it is a mid-size truck back seat: fine for children, fine for adults across town, and snug for a grown adult behind a tall driver on a two-hour drive. The practical questions parents ask are about doors and access, and this is where the crew cab earns its place. Full-width rear doors open wide enough to lean in and buckle a chair without contorting, and the flat floor makes it easier to reach the far seat. Two car seats across the second row is routine. Three across is possible with narrow seats, but go try yours in the vehicle before you commit, because seat width varies more between car seat brands than between trucks. ===================== H2 2 ===================== Where the gear goes This is the part families underestimate. An SUV makes you choose between passengers and cargo. A truck does not. The Canyon's bed holds 41.9 cu. ft., measuring 5.1 ft. long and 4.8 ft. wide, and none of that space competes with the people inside. Strollers, ball bags, camping gear, a weekend of luggage, mulch from the garden center, a bicycle laid flat: all of it goes behind the cab rather than on top of somebody's lap. For a family that hauls dirty or bulky things on a regular basis, that separation is the actual argument for a truck over a crossover, and it is worth more day to day than a tow rating most buyers rarely use. Measurement 2026 Canyon Seating Up to 5, crew cab only Front legroom 45.2 in. Rear legroom 34.7 in. Front headroom 40.3 in. Cargo bed volume 41.9 cu. ft. Overall length 213.2 in. Overall height 79.8 in. Width, mirrors folded 72.4 in. Full dimensions by trim, including curb weight and ground clearance, live on the Canyon specs and dimensions page. ===================== H2 3 ===================== Living with it Monday through Friday A family vehicle has to survive the school line, the grocery lot and the garage, and this is where the mid-size footprint pays off. The Canyon is 213.2 in. long on a 131.4-in. wheelbase, 72.4 in. wide with the mirrors folded and 84.4 in. across with them extended, and 79.8 in. tall. Those numbers put it closer to a large SUV than to a full-size pickup, which is why it fits in standard parking spaces and most residential garages. Measure your door opening against that 79.8-in. height if the clearance is close, because a roof rack changes it. Fuel matters when the truck is also the daily driver. A rear-wheel-drive Elevation is EPA-rated 19 mpg city, 23 highway and 20 combined. Add four-wheel drive, or step up to the AT4 or Denali, and the rating is 17 city, 22 highway and 19 combined. The AT4X, with its off-road hardware and tires, is rated 17 mpg across the board. The tank holds 21.4 gal., which is a comfortable range for school runs during the week and a trip to Crater of Diamonds State Park or Hot Springs National Park on a Saturday. Every Canyon runs the same 2.7L TurboMax engine and an 11.3-in. touchscreen with Google built-in and wireless Apple CarPlay and Android Auto, so the technology parents care about does not require moving up a trim. GMC Pro Safety is standard across the lineup as well. ===================== H2 4 ===================== When a Canyon is the wrong answer We would rather tell you this before you buy than after. The Canyon is not the right vehicle if: You need more than five seats. There is no third row and no bench option. A GMC Acadia or a Yukon is the answer, and we stock both. Adults ride in the back every day. At 34.7 in. of rear legroom, a full-size truck or a three-row SUV will be more comfortable on long trips. Your cargo needs to stay dry and locked without extra equipment. An open bed is an open bed. A tonneau cover solves it, and our parts department can price one. If those points push you toward more capability rather than more seats, the honest comparison against the class benchmark and the platform twin is written up on the Canyon vs Tacoma page and the Canyon vs Colorado page. ===================== H2 5: DECISION BLOCK ===================== Which trim makes the most sense for a family Best value for a family daily driver: Canyon Elevation. Cloth seats you can clean, the full technology package, and the highest combined rating of the four trims, 20 mpg in rear-wheel drive. Gravel roads, ball fields and weather: Canyon AT4. Standard four-wheel drive and an automatic locking rear differential for the days the driveway is a mess. The truck is also the nice family car: Canyon Denali. Perforated leather-appointed seating and the quietest cabin of the four. Trail hardware over comfort: Canyon AT4X, understanding the ride and the fuel economy both reflect the off-road tires. Trim-by-trim equipment and current pricing sit on the Canyon trims page. If you want the whole picture in one place, the Canyon research hub collects every page we have written on the truck, including the model overview, the towing capacity page, the AT4 and AT4X off-road page, the maintenance schedule and a full set of Canyon FAQs. ===================== FAQ ===================== Questions parents ask us Can you fit two car seats in a GMC Canyon? Yes. Every 2026 Canyon is a crew cab with full-size rear doors and seating for up to 5, and two car seats across the second row is routine. Three across depends on how wide your specific seats are, so bring them in and we will test-fit them before you buy. How much rear legroom does the 2026 Canyon have? The second row has 34.7 in. of legroom, against 45.2 in. in front. That is comfortable for children and workable for adults on shorter drives, and tight for a tall adult behind a tall driver on a long one. Does the GMC Canyon have a third row? No. The Canyon is a five-seat crew cab in every trim, with no third row and no bench option. Families who need six or more seats should look at a three-row SUV such as the GMC Acadia or Yukon. Will a GMC Canyon fit in a standard garage? Usually. The Canyon is 213.2 in. long, 79.8 in. tall and 72.4 in. wide with the mirrors folded, which is closer to a large SUV than a full-size truck. Measure your garage door height first if the clearance looks close. What gas mileage does the Canyon get as a daily driver? A rear-wheel-drive Elevation is EPA-rated 19 mpg city, 23 highway and 20 combined. Four-wheel-drive Elevation, AT4 and Denali models are rated 17 city, 22 highway and 19 combined, and the AT4X is rated 17 mpg across the board. ===================== CTA ===================== Bring the car seats and try it Measurements only get you so far. The way to settle this is to put your car seats in the actual truck, sit behind them, and see whether the fit works for your family. We keep Canyons on the lot for exactly that, and there is no pressure attached to an afternoon of test-fitting. Families drive over from Benton, Bryant, Malvern and Hope to do it, and race-week traffic around Oaklawn is the only thing that slows the trip down. Browse new Canyon inventory, the full new inventory lineup, or every new GMC on the lot if a three-row Acadia or Yukon turns out to be the better fit. If the payment matters more than the model year, our used inventory and certified pre-owned trucks are worth a look first. Already own one and need the cabin filter changed before allergy season? Our GMC-certified service department handles it, and you can schedule service online. When you are ready, value your trade, start financing, book a test drive, or contact us at (501) 881-4160. Family-owned since 1967, and still treating buyers that way. EPA-estimated ratings. Your actual mileage varies with driving conditions, load and maintenance.
