What are the key differences between the 2025 Kia Carnival and 2025 Toyota Sienna?

The 2025 Kia Carnival and the 2025 Toyota Sienna have several key differences, beginning with their sizes. The Carnival is the lighter of the two vehicles, but it features a longer wheelbase and offers slightly more ground clearance, legroom, headroom, and cargo space than the Toyota Sienna.
While the 2025 Kia Carnival MPV lineup includes five trims, the 2025 Toyota Sienna is available in six trims, but this does not mean that the Toyota minivan has more to offer. Both model lineups are incredible people transporters with spacious, comfortable interiors, connectivity, and more, but look closer and see that the Kia has what Car and Driver called a Mercedes-style dual-screen infotainment system plus accessibility to navigation and entertainment made easy.
Every 2025 Kia Carnival trim has a powerful 3.5L V6. When this power is combined with the towing package, your Carnival transforms into a pulling machine with a towing capacity of 3,500 pounds, so the extra equipment or jetskis, motorcycles, ATVs, and small trailers never gets left behind.
The 2025 Toyota Sienna trims have an Inline four-cylinder engine but boast a 3,500 towing capacity when properly equipped. Other differences include the 2025 Kia Carnival's 8-speed transmission, which differs from the continuously variable-speed automatic transmission, and the available interior seating material.
Which has better gas mileage: 2025 Kia Carnival or the 2024 Toyota Sienna?
Since the 2021 models, every Toyota Sienna has been a hybrid, which gives it better gas mileage than an all-gas model like the 2025 Carnival MPV. For a Kia hybrid, look at the 2025 Carnival MPV Hybrid.
In a side-by-side comparison by the EPA, the 2025 Kia Carnival, an all-gas model, gets a combined 21 MPG (city/highway) with a driving range of 399 miles compared to the 36 MPG combined of the 2024 Toyota Sienna hybrid engine/transmission setup.
Why buy the 2025 Kia Carnival MPV?
Buy the 2025 Kia Carnival MPV if you want a multipurpose vehicle with three rows of seating that can accommodate seven to eight passengers and still have plenty of room for cargo, bags, and equipment.
The 2025 Kia Carnival MPV is more than a minivan; it is enhanced comfort with a spacious interior, large displays for easy navigation and streaming entertainment control plus cupholders, armrests, heated front seats, leather accents for the steering wheel and gearshift knob, Sirius XM, Remote Start, the Smart Power Liftgate, wireless Apple CarPlay and Android Auto plus the signature second-row Slide-Flex seating.
