Comparison scope
Clear-Cut Answer
Kia’s official tables show substantial continuity between the 2026 and 2025 gasoline Carnival. Both list five trims, the same 3.5-liter V6 output, the same core dimensions and cargo figures, and the same published braked towing capacity.
That makes this a configuration and vehicle-level decision, not a simple newer-is-different decision. Compare trim, installed packages, seating arrangement, condition, availability, and transaction terms on the exact vehicles.
The tables do not prove that every component or running change is identical. They do show that the central published specifications remain closely aligned across the two model years.
Both model years publish LX, LXS, EX, SX, and SX Prestige gasoline trims.
Both official tables list a 3.5-liter V6 with 287.1 horsepower and 260.4 pound-feet of torque.
Both list a 121.7-inch wheelbase and 203.0-inch overall length.
Both list 40.2 cubic feet of minimum and 145.1 cubic feet of maximum cargo volume.
Both list 3,500 pounds of braked towing capacity, subject to equipment and operating requirements.
2026 and 2025 Carnival gasoline-model comparison
| Decision point | 2026 Carnival | 2025 Carnival | Shopper meaning |
|---|---|---|---|
| Trim structure | LX, LXS, EX, SX, SX Prestige | LX, LXS, EX, SX, SX Prestige | Start with the same five trim names, then verify installed equipment. |
| Gasoline engine | 3.5-liter V6, 287.1 horsepower, 260.4 pound-feet | 3.5-liter V6, 287.1 horsepower, 260.4 pound-feet | Core published output does not separate the model years. |
| Wheelbase and length | 121.7-inch wheelbase, 203.0-inch length | 121.7-inch wheelbase, 203.0-inch length | The published exterior footprint stays aligned. |
| Cargo volume | 40.2 minimum, 145.1 maximum cubic feet | 40.2 minimum, 145.1 maximum cubic feet | Use an in-person loading check to settle shape and access. |
| Braked towing capacity | 3,500 pounds | 3,500 pounds | Confirm equipment, loading, and operating requirements on the exact vehicle. |
Figures come from Kia America’s U.S. 2026 and 2025 Carnival specification and feature tables. Published continuity does not prove every component is identical.
Compare exact vehicles, not model-year labels
Once the core specifications match, trim, seating, packages, condition, availability, and terms become the useful differences.
Comparison guardrail
Read this as a published-specification comparison
Kia America publishes the gasoline Carnival in LX, LXS, EX, SX, and SX Prestige trims for both 2026 and 2025. The corresponding tables also list the same 3.5-liter V6 output: 287.1 horsepower and 260.4 pound-feet of torque. That evidence supports a continuity-first comparison.
Continuity-first does not mean identical in every detail. Production changes, packages, colors, installed accessories, and individual vehicle history can still matter. The responsible conclusion is narrower: the central published gasoline-model specifications do not create a major powertrain or size split between these two years.
That shifts the shopping process toward the exact vehicles available. Compare trim, seating arrangement, installed packages, condition, mileage when applicable, warranty status, and transaction terms. A model-year label alone cannot replace those checks.
Keep Carnival Hybrid outside this table. The claims here apply to the gasoline Carnival, and the hybrid system has a different powertrain and published ratings. Separating those paths prevents a gasoline-year comparison from absorbing unrelated hybrid specifications.
Three fast decisions
Quick Pick
Question 1
Which exact trim carries the equipment you need?
Question 2
Does the seating arrangement match the passenger plan?
Power and footprint stay on common ground
The official 2026 and 2025 tables list the same 3.5-liter V6 output at 287.1 horsepower and 260.4 pound-feet. If the comparison is between two gasoline Carnivals, engine output does not provide a reason to choose one model year over the other.
The published exterior footprint is also aligned. Both tables list a 121.7-inch wheelbase and 203.0-inch overall length. Parking-space planning, garage clearance, and passenger access still need an in-person check, but the model-year tables do not show a basic length or wheelbase change.
Cargo figures follow the same pattern. Both list 40.2 cubic feet as the minimum and 145.1 cubic feet as the maximum. Those figures are useful for broad comparison, while the shape of the load, seat arrangement, and loading opening determine whether a specific object fits.
Use this shared foundation to shorten the test. You do not need separate assumptions about output or overall footprint. Instead, spend the time on the exact trim, the passenger plan, and the features that differ between the vehicles in front of you.
Trim and seating carry more weight than the year badge
Both years use the same five gasoline trim names, but matching names do not guarantee matching inventory. Packages, seating arrangements, exterior details, and convenience equipment can change the usefulness of two otherwise similar Carnivals. Verify the window label, listing, and physical vehicle together.
Begin with passenger count and second-row use. Place the child seats or passenger plan into the exact seating arrangement, then check third-row entry and cargo access. The shared 40.2-to-145.1-cubic-foot range cannot tell you whether one installed seat package fits your family better.
Next, compare the features that matter every week: camera views, cabin communication tools, climate controls, charging, audio, driver-assistance settings, and liftgate operation. Record what is actually present instead of assuming every feature follows from the model year or trim name.
For a used 2025 vehicle, condition and service records add another layer. For a new 2026 vehicle, current availability and terms may matter more. Neither year receives an automatic verdict. The better fit is the exact Carnival that passes the passenger, equipment, condition, and budget checks.
Treat towing as an exact-vehicle setup
Kia’s official tables list 3,500 pounds of braked towing capacity for both gasoline-model years. That shared figure means the published rating does not separate a 2026 from a 2025 Carnival in this comparison.
The number is not the whole setup. Installed equipment, passenger and cargo load, trailer weight, hitch equipment, maintenance condition, and the owner instructions all matter. Confirm those requirements for the exact vehicle and trailer before planning a tow.
If towing is not part of your use, do not let the 3,500-pound figure dominate the decision. Spend the comparison time on seating, cargo access, everyday controls, and the transaction. If towing is part of the use, make the equipment and loading review a separate dealership conversation.
Keep the gasoline boundary visible here as well. Carnival Hybrid uses a different system and should be researched against its own exact-year ratings. Mixing the two powertrains would make the comparison less precise.
Use one side-by-side Carnival scorecard
- Confirm that both vehicles are gasoline Carnival models and record the exact trim.
- Verify the seating arrangement and test third-row access with the regular passenger plan.
- Load representative gear instead of relying only on the shared 40.2-to-145.1-cubic-foot range.
- Check every installed technology and convenience feature on the physical vehicle.
- If towing matters, confirm the 3,500-pound rating, required equipment, loading, and instructions.
- Compare condition, mileage when applicable, warranty status, availability, and transaction terms before choosing.
