2026 Kia Carnival Vs. Honda Odyssey: Performance, Interior & More

See how two high-profile minivans measure up in our Honda Odyssey vs. Kia Carnival guide. Here, we'll discuss the impressive V-6 performance offered by each model and the small differences that make each unique. Ultimately, the Honda Odyssey excels as a modern, fuel-efficient three-row family vehicle with ample cargo space. The auto experts here at Planet Honda invite you to take a closer look at these two minivans before you visit your local Honda dealership for a personalized tour and family-friendly test drive.

Performance & Specs

Let's kick off our matchup by examining how each minivan in our 2026 Kia Carnival vs. Honda Odyssey comparison performs. Both are outfitted with a 3.5-liter V-6 engine, but the specs vary slightly. The Kia Carnival makes a tad more horsepower than the Odyssey: 287 and 280 horsepower, respectively. Meanwhile, the Honda Odyssey has a pinch more torque, offering 262 pound-feet, while the Kia Carnival produces 260 pound-feet.

Given their similar powertrain and output specs, as you might expect, these models have the same 3,500-pound maximum towing capacity. You can pull this much in every configuration of both minivans, so towing is a tie as well. However, as you'll see below, that's where the performance similarities end and the Honda Odyssey starts to pull ahead.

In all other performance aspects, the Honda Odyssey has a leg up on its competitor. Outfitted with a 10-speed automatic transmission, you'll enjoy smooth-shifting gear changes and improved fuel efficiency. Every variant of the 2026 Honda Odyssey earns an EPA-estimated 19/28/22 MPG (City/Highway/Combined).³

By contrast, the 2026 Kia Carnival is outfitted with an eight-speed automatic transmission that aids the minivan in earning fine, albeit lower, fuel ratings. Every 2026 Carnival model earns an EPA-estimated 18/25/21 MPG (City/Highway/Combined).⁴ Although decent, these fuel efficiency values don't add up to those of the Honda Odyssey.

Interior & Exterior Dimensions

Before carting the family around in a new minivan, you'll likely want to consider space and comfort. The Odyssey and Carnival are comparably sized, though the Honda model is a tad longer at 205.2 inches compared to the Kia, which is 203 inches long. The Honda Odyssey also provides a better view of the road ahead, thanks to its high positioning at 69.6 inches tall. The Kia Carnival doesn't measure up, with only 68.5 inches on models without roof rails. The available rails do bring the height up to 69.9 inches, but they won't enhance your visibility.

So, we know the Honda Odyssey edges out the competition in exterior measurements, but what about a Kia Carnival vs. Honda Odyssey interior dimensions matchup? The two remain fairly comparable in headroom, shoulder room, hip room, and legroom, with the Kia Carnival delivering a little more in some areas. However, if you're looking to fit teenagers or adults in the third row, the 2026 Honda Odyssey is the way to go. It offers more third-row legroom and shoulder room than its Kia rival.

Passenger space is just one variable in the interior measurements equation, though. Moving on to the Honda Odyssey vs. Kia Carnival cargo room values, the clash is still a close one. The Honda Odyssey offers up to 38.6 cubic feet of load space when all three rows of seating are upright, including space between rows. On the other hand, the Kia Carnival has 40.2 cubic feet of space behind its third row, giving it a slight advantage.

However, if you're looking to maximize room for gear or furniture, the Odyssey once again comes out on top. With both the second and third row folded, the Honda minivan has a maximum cargo volume of 155.8 cubic feet. Compare that to the Kia's maximum capacity of 145.1 cubic feet, and you can bring along more than 10 cubic feet of additional belongings in a new Odyssey.

Trims & Pricing

As far as pricing goes, the Honda Odyssey minivan starts at a slightly higher MSRP than the Kia Carnival MPV. As you'll see below, though, the Odyssey features menu is well worth its starting price point.

There are four tiers to the 2026 Honda Odyssey trim lineup, giving you plenty of choice, while offering more per upgrade than the five-trim Kia Carnival selection for 2026. The Odyssey is available in the following editions:

• 2026 Honda Odyssey EX-L
• 2026 Honda Odyssey Sport-L
• 2026 Honda Odyssey Touring
• 2026 Honda Odyssey Elite

The base EX-L trim comes with impressive standard features like leather-trimmed seats, a power tailgate with programmable height, a one-touch power moonroof with a tilt feature, wireless device charging, power-sliding doors, tri-zone automatic climate control, second-row sunshades, and several advanced driver-assistance features.

The 2026 Kia Carnival comes in these five trims:

• 2026 Kia Carnival LX
• 2026 Kia Carnival LXS
• 2026 Kia Carnival EX
• 2026 Kia Carnival SX
• 2026 Kia Carnival SX Prestige

With its lower starting MSRP, you can expect fewer advanced tech systems and modern creature comforts in the entry-level Carnival. For starters, it has standard cloth seating – you'll have to upgrade to the range-topping model to get leather upholstery. While it does get power-sliding rear doors and a tri-zone automatic climate system as standard, like the Odyssey, you'll start off with a manual rear liftgate, and you won't get second-row sunshades or a wireless device charger until the third tier.

Comfort & Space

As you can see in our dimensions chart above, the Honda Odyssey minivan offers more maximum cargo space than the Kia Carnival. With up to 155.8 cubic feet, you can fit way more in the Odyssey than the 145.1 cubic feet of maximum cargo area in the Carnival.

In addition to the cargo area, rear-seat passengers get more legroom in the Honda minivan than in the Kia model. If you're looking for a van with plenty of space for gear and people, the Honda Odyssey is your match.

Comfort amenities abound in both models, though you'll get more of them as standard equipment with the Honda Odyssey. In addition to the features already mentioned, here are some other major comfort differences between the Odyssey and the Carnival:

• Standard Driver's Seat
• Odyssey: 12-way power adjustability with four-way power lumbar support and two-position memory
• Carnival: Six-way manual adjustability
• Standard Front-Passenger Seat
• Odyssey: Eight-way power adjustability with four-way power lumbar support
• Carnival: Four-way manually adjustable
• Heated Front Seats
• Odyssey: Standard
• Carnival: Available

Tech Features

Both minivans have wireless Apple CarPlay® and Android Auto™, as well as similar options for sound systems. The Honda Odyssey starts out with a seven-speaker system that can be upgraded to 11 speakers, whereas the Kia Carnival starts with six speakers but can reach up to 12. The Carnival also has a slightly larger touchscreen at 12.3 inches compared to the 9-inch display in the Honda Odyssey. That's about where the advantages end for the Kia model, though.

The Honda Odyssey comes standard with a CabinTalk In-Car PA System so you can communicate with your little ones without shouting. You also have the option for an available CabinWatch Rear Seat Monitor to keep an eye on what's happening in the back rows without having to turn around. Do you want to lower the chances of back-seat squabbles while you're driving even more? Opt for the available advanced rear entertainment system with a 12.8-inch high-resolution screen to keep your children occupied.

While the Kia Carnival does offer a rear entertainment system, it's an optional add-on that's only available for the top-tier trim – the Odyssey gives you its rear entertainment system as standard equipment on the top two trim levels. You won't find anything like CabinTalk or CabinWatch in the Carnival's feature menu or add-ons.

All things considered, both the new Honda Odyssey for sale and the latest edition of the Kia Carnival are high-quality minivans crafted with expert care and premium materials.
