Late October through January, Nashville families load up and head east on I-40 for Thanksgiving, Christmas, and New Year's in Knoxville and the Smoky Mountains beyond. That corridor runs 180 miles of perfectly good interstate, right up until it isn't. East of Cookeville, I-40 climbs onto the Cumberland Plateau with long, sustained grades, the kind that separate a genuinely capable three-row SUV from one that just looks the part.
The 2026 Palisade is a whole new vehicle. Hyundai redesigned it from the ground up this model year, adding a hybrid powertrain for the first time, stretching the wheelbase, and packing in enough cabin technology to keep three rows of family reasonably civil. On the East Tennessee holiday runs, the grades and the fuel bill are the two things a loaded three-row really has to answer for, and the 2026 Palisade answers both more directly than its predecessor did.

Does the Palisade Actually Fit This Drive?
Yes, the Palisade fits this drive well, with one real caveat we'll come back to, because the grades east of Cookeville and the 180-mile fuel leg are precisely the two demands this redesign was built to handle, and the rest of the route is ordinary interstate you could do in anything. The table below lines the vehicle up against the specific demands of I-40 East.
| Local condition on I-40 East | Palisade feature that handles it | Why it matters on this route |
|---|---|---|
| Cumberland Plateau long grades east of Cookeville | Hybrid: 329 hp / 339 lb-ft torque (Hyundai); V6: 287 hp / 260 lb-ft | 30% more torque on the hybrid means the engine isn't hunting for a downshift on sustained climbs with a full load |
| 180-mile corridor, limited urban refueling after Cookeville | Hybrid FWD EPA-estimated 34 mpg combined; 619-mile total range | The full Nashville-to-Knoxville run fits inside one tank leg with headroom to spare |
| Fall and early winter crosswinds on the exposed plateau | HTRAC AWD available on multiple trims | Lateral stability on bridge and reservoir valley segments where winds pick up |
| Holiday luggage for five to eight passengers | Up to 87 cu ft cargo behind front seats; 19 cu ft behind third row | Two large checked bags and carry-ons fit behind the upright third row; fold it for maximum gear |
| Long-haul highway fatigue over 2.5-3 hours | Navigation-based adaptive cruise control standard | Reads mapped speed changes and grade transitions; less driver effort on the plateau's rhythmic climbs |
| Time zone change near mile 340 (Eastern Time) | 12.3-inch digital cluster with integrated navigation | Clocks update, route adjusts automatically |
| Three rows of family members across 2.5-plus hours | USB-C ports in all three rows; tri-zone automatic climate | Everyone charges their device; rear passengers control their own temperature |
The Hybrid Powertrain Changes the Fuel Equation on This Route
The hybrid is the biggest practical change between the 2026 Palisade and every version before it, and on this corridor it reshapes the fuel math, though the standard V6 still earns its keep if you plan to tow, so the better pick really depends on what you're hauling east for the holidays. The 3.5-liter V6 stays the engine in the standard trims, and it returns 19 city, 25 highway, 21 combined mpg, EPA-estimated on FWD. That's a competitive number for a three-row, but not a standout.
The Palisade Hybrid pairs a turbocharged 2.5-liter four-cylinder with dual electric motors for a combined 329 horsepower and 339 lb-ft of torque. The EPA rates the Hybrid FWD at 33 city / 35 highway / 34 combined mpg on the SEL and SEL Premium trims, and 31/32/31 mpg for the larger-wheeled Limited and Calligraphy FWD trims. Choose AWD and you're at 29/30/29 mpg EPA-estimated. The spread is meaningful depending on trim. Worth knowing before you configure.
On a practical 180-mile holiday run at 70 mph, that hybrid efficiency isn't just a number on a window sticker. The plateau section between Cookeville and Rockwood is where a loaded three-row V6 really works, burning fuel at a higher rate than flat-road cruising. The hybrid's electric assist smooths exactly that scenario, with torque available right off the bottom of the powerband and no need to rev the engine up to build it.
One honest tradeoff is worth flagging before you pick. The Hybrid is rated at 4,000 pounds of towing capacity when properly equipped, while the V6 hits 5,000 pounds. If you're pulling a lightweight camper or a small boat to Douglas Lake after Christmas, the V6 remains the right call.

Three Rows, Seven or Eight Passengers, and the Real Story on Space
You get real family space here, with a second row that's comfortable for adults and a third row that genuinely seats people rather than punishing them, though it turns snug for taller passengers on a multi-hour run, so the fair way to frame it is roomy for five or six and workable for more. The Palisade grew for this generation. Hyundai stretched the overall length to 199.2 inches and extended the wheelbase by 2.7 inches, and that extra room flows straight into the interior.
The second row is genuinely comfortable for adults. Legroom there is generous, and the captain's chairs on SEL and above tilt forward at the push of a button for easy third-row access.
How does the third row really hold up? It seats adults, and it does fit them without the contortions some three-rows require, but it gets snug for anyone over 5'10" on a multi-hour run. Every three-row in the class works the same way. For kids and teenagers, it's fine. For grandparents with stiff joints, you'll want them in row two.
Cargo measures 19 cubic feet behind the upright third row (enough for several carry-on bags and a weekend's worth of gifts) or up to 87 cubic feet when both rear rows fold. The power-folding 60/40 third-row seat means you're not wrestling with it in a Knoxville parking garage while it's raining.
The cabin itself stays quiet at highway speeds. Navigation-based adaptive cruise control reads the mapped grade ahead and adjusts throttle ahead of the climb instead of reacting once you've already lost speed. On the plateau's long pulls, that makes a real difference in how composed the drive feels with a full load.

What to Know Before You Head East for the Holidays
A few things make this drive smoother, and most of them come down to timing and weather rather than the vehicle, so plan your departure around holiday traffic, keep an eye on the plateau forecast once December hits, and size your luggage to your passenger count before you ever load the trunk.
Plan your departure time. I-40 East out of Nashville sees peak weekend traffic on Friday afternoons. The I-40/I-24 interchange in Nashville adds time depending on where you're starting in the metro, so build in a buffer if you're leaving after work on Thanksgiving Wednesday or Christmas Eve.
AWD versus FWD on this route in late fall. October and November run mostly dry on I-40, while December brings occasional ice near the plateau elevations, especially on bridge decks. If you visit Knoxville often and make several winter runs, AWD makes practical sense on the Hybrid or the V6. If you're doing one or two trips a season, FWD with the better hybrid mpg is the more sensible call. Tennessee's SmartWay system from TDOT publishes live road conditions, and checking it before a December departure takes two minutes.
The Cookeville stop. About 80 miles from Nashville, Cookeville sits right off I-40 near exit 287 and makes the natural mid-trip break. You won't need fuel in the Hybrid, but a restroom stop and a coffee refill for the driver are worth it before the plateau grades begin.
On luggage. In our experience, if you're traveling seven or eight passengers plus holiday gifts plus a dog, treat the third row as luggage space and take a second car or rent a rooftop carrier. Seven passengers with bags fills a Palisade. Eight passengers with bags becomes a real packing exercise. At five or six passengers, everything fits.
