Toyota Sienna vs Kia Carnival

Minivan or SUV? Soccer momobile or soft-roader? The choice between practicality or vanity is no longer such a stark contrast. Minivans such as the Kia Carnival and Toyota Sienna have narrowed the style gap to appear more like their SUV kin, but there’s no masking those brilliant power sliding side doors on the dad-bods of the smartest three-row vehicles on sale today. 

The minivan is roomier, more efficient, and more practical in transporting more than four passengers. The 2025 Kia Carnival smartens up with a new hybrid option to better compete with the uber-practical 2024 Toyota Sienna, which comes standard as a hybrid with a 36 mpg combined rating with front-wheel drive, or 35 mpg combined with all-wheel drive. That’s something the refreshed Carnival still doesn’t have, however. 

The Carnival’s SUV style, roomier interior, and value-loaded feature set improves for 2025, but it also gets more expensive. We’ll update this once we get seat time and official EPA ratings for the 2025 Carnival. The Sienna carries over for 2024 and remains one of if not the most practical family car on sale, priced within $1,000 of the new Carnival. 

Each minivan appeals in different ways, and here’s how they stack up bit by bit. 

Toyota Sienna vs. Kia Carnival prices, features, and trims

• Carnival LX starts at $37,895 and runs to $53,995 for Hybrid SX Prestige
• Toyota Sienna hybrid ranges from $38,580 to $55,000
• Our picks: Kia Carnival EX, Toyota Sienna LE

Which Kia Carnival should I buy?

The base Carnival LX costs $37,895, including the mandatory $1,395 destination fee. To stay on par with the Sienna and its hybrid powertrain, we’d step up to the LXS over the base LX, since you can’t option the hybrid on that model. The 2025 Carnival LXS Hybrid costs $41,895, including the $1,395 destination fee. Are you getting $3,300 more in features, and a roomier interior with a more alluring style?

Maybe.

It’s equipped with a 12.3-inch touchscreen with wireless Apple CarPlay and Android Auto, six USB ports, heated front seats covered in synthetic leather upholstery, a power driver’s seat, eight seats, and a suite of driver-assist technology. 

Fully loaded, a Carnival SX Prestige Hybrid has leather upholstery, 12-speaker Bose sound, and a surround-view camera system for $53,995.

Another advantage over the Toyota? Every Carnival comes with a 5-year/60,000-mile warranty

Which Toyota Sienna should I buy?

The Sienna has a 3-year/36,000-mile warranty, but it includes two years or up to 25,000 miles of scheduled maintenance. That’s nice if you like your dealer.

A standard hybrid, the Toyota Sienna comes with several trim options, including LE, XLE, XLE Woodland, XSE, Limited, and Platinum. The base LE costs $38,850, including a $1,395 destination fee. It has the expected modern minivan basics, power sliding doors, a raft of safety technology, and a 9.0-inch touchscreen with Android Auto and Apple CarPlay. It’s the best deal, and the one we’d recommend for the more proletariat Sienna. 

Step up to the Sienna XLE for a few thousand more, and you’ll get a sunroof and synthetic leather upholstery. The fancy Sienna Limited adds in leather upholstery, JBL audio, navigation, and an in-car intercom for the driver to connect with passengers in the rear. A Sienna Platinum with all-wheel drive runs more than $55,000.

The Carnival feels more premium inside but not only is the Toyota Sienna a better deal, it can also be optioned with all-wheel drive for $2,000 extra on all but the XLE Woodland, where it comes standard.

Advantage: The Sienna packs more value.

2024 Toyota Sienna

Toyota Sienna vs. Kia Carnival size, comfort, and cargo space

• Sienna’s cargo specs: 33.5 cubic feet behind third row; 75.2 behind second row ; 101 behind front row 
• Carnival cargo specs: 40.2 cubic feet behind third row; 86.9 behind second row ; 145.1 behind front row has more cargo space, however
• Both seat up to eight passengers in comfort

The minivan outsmarts the SUV in every aspect when it comes to seating for eight, flexibility, versatility, and overall roominess. In both minivans, a recessed tub in the rear can hold the collapsed third row in the floor, leaving so much more cargo room than in an SUV. Power-sliding side doors make family life easier, and can usher little ones in their child safety seats without a parent needing to break their back to put them in. Though no other minivan has the Chrysler Pacifica’s famed Stow ’n Go second-row seats that hide into the floor to transform the minivan into a cargo van.

How big is the Kia Carnival?

The Carnival out-specs the Sienna, but even if you can’t always trust automakers’ ever-changing measurement standards, the Carnival is roomier in addition to being more upscale. The top SX Prestige offers second-row captain’s chairs with optional collapsible legrests. Younger kids can nap well on road-trips, but an adult or a rangy teen won’t fit without tucking in. The second row seats slide on a track that lets you move them fore and aft, but also shift them inboard for an easy access lane to the back or away from each other for a lane down the middle. Most Carnivals come with a second-row bench seat with a sliding middle seat that folds down to serve as a console, or stays up to grant it eight-passenger seating. These seats can be removed, unlike in the Sienna.

How big is the Toyota Sienna?

The Sienna isn’t as roomy, but it has practical storage spaces everywhere, including  a storage shelf across the front passenger side for phones and whatnots. It has a two-tiered center console for deep storage, too. Leather’s an option, but Kia’s is nicer. 

The second-row Sienna seats have more than 25 inches of back-and-forth slide to them, the better to fit captain’s chairs with manual flip-out footrests. It works a bit better in the Sienna, though not if there’s someone in the third row. The tradeoff? The Sienna’s middle seats can’t be removed. Toyota’s solution: allow the seat bottoms to flip up, then the whole unit can slide forward against the front seat backs. Third-row access is a little more cumbersome with the Sienna’s latches. 

Advantage: Kia Carnival. 

2024 Toyota Sienna

Carnival vs. Sienna safety

• Both have standard automatic emergency braking with pedestrian detection
• Sienna earned a Top Safety Pick+
• Surround-view camera systems can be equipped on either

The Sienna and Carnival come well-equipped with technology designed to avoid or mitigate crash impacts. They have standard automatic emergency braking with pedestrian detection, blind-spot monitors, and active lane control, but Toyota adds adaptive cruise control as standard. 

How safe is the Kia Carnival?

The NHTSA still hasn’t tested the Carnival, and the IIHS gave the 2024 model a Top Safety Pick, so long as it’s fitted with the SX Prestige’s LED projector headlights. Other versions get “Poor” headlights but maintain excellent crash-test scores. We’ll update this once the 2025 model is tested. 

Driver-assist options include blind-spot cameras that project side views into the instrument cluster, adaptive cruise control, high-speed automatic emergency braking, and a surround-view camera system. 

How safe is the Toyota Sienna?

The Sienna earns a Top Safety Pick+ designation and a five-star NHTSA rating, though the feds found fault in its front driver impact tests..

Toyota equips the Sienna with adaptive cruise control, automatic emergency braking, blind-spot monitors, rear cross-traffic alerts, active lane control, and automatic high beams. Options include a surround-view camera system, head-up display, front and rear parking sensors, and a digital rearview mirror with a camera view that helps see beyond all the heads bobbing in those six rear seats.

Advantage: Toyota Sienna.
