How Do the 2026 Kia Carnival and 2026 Toyota Sienna Compare?

The right minivan matters to drivers who want a vehicle with flexible interior space, plenty of safety tech, and versatile cargo space. For 2026, two top contenders for many minivan fans are the 2026 Kia Carnival MPV and the Toyota Sienna. These are built to meet the needs of families and drivers who need space, power, and tech. As a dedicated Kia dealership near Atlanta and Douglasville, Calavan Kia of West Atlanta is partial to the Carnival MPV, and we’re confident you will be, too.

Let’s compare the 2026 Kia Carnival and 2026 Toyota Sienna so you can decide which minivan is best for your family around Atlanta and Lithia Springs.

Which Minivan is the Best Choice for Atlanta-Area Drivers?

Atlanta-area drivers look for vehicles that provide safe, comfortable, fuel-efficient transportation for their individual needs. While minivans are popular with families, let’s look at the reasons why families like the Kia Carnival and Toyota Sienna.

The Kia Carnival is one of the best looking minivans available on the market today, mostly because it looks more like an SUV than a minivan. Despite its SUV styling, it’s all minivan on the inside, with flexible interior space and 40.2 cubic feet of cargo space with all three rows in place.

On the other hand, the Toyota Sienna has the curves and angles that look like a minivan. Like the Carnival, it has flexible interior space, but only 33.5 cubic feet of cargo space behind the third row.

For 2026, Kia added a hybrid powertrain, so the multi-purpose vehicle is available with two powertrains. The Toyota Sienna is only available with a hybrid powertrain. Both hybrid models have exceptional fuel efficiency.

Drivers can choose their Kia Carnival or Toyota Sienna with two configurations:

• Seating for eight with a second-row bench
• Seating for seven with second-row captain’s chairs

In typical minivan style, both models have features that drivers want:

• Sliding rear doors
• Large infotainment systems
• Optional rear-seat entertainment systems
• Folding seats for additional cargo space
• Impressive standard safety features

The two vehicles have notably different warranty programs. The Kia Carnival MPV comes with the legendary 5-year/60,000-mile bumper-to-bumper warranty, while the Toyota Sienna has a 3-year/36,000-mile bumper-to-bumper warranty. Toyota offers the Sienna in six trim levels, while the Kia Carnival has five trims. The Sienna Hybrid has a higher MSRP than the Kia Carnival with the standard gas-powered engine, but the Carnival Hybrid has a higher MSRP than the Toyota Sienna.

What Powers the 2026 Carnival and 2026 Sienna?

What’s under the hood matters to minivan drivers, as the powertrain has to help drivers with daily errands and provide ample power on highway road trips. The 2026 Kia Carnival is available with two powertrains:

• The gas-powered model has a 3.5-liter V6 with front-wheel drive, an eight-speed automatic transmission, and 287 horsepower with 260 lb-ft of torque.
• The Carnival Hybrid has a turbocharged 1.6-liter four-cylinder with a single electric motor, front-wheel drive, a six-speed automatic transmission, and 242 horsepower.

The 2026 Toyota Sienna is only available with one powertrain: a 2.5-liter four-cylinder engine with two electric motors, standard front-wheel drive, a continuously variable automatic transmission, and 245 horsepower. Toyota offers the Sienna with all-wheel drive and adds a third electric motor, but without adding horsepower.

Fuel ratings for all three 2026 models are as follows:

• The Toyota Sienna with front-wheel drive gets an EPA-estimated 36 MPG combined.
• The Kia Carnival MPV Hybrid with front-wheel drive gets an EPA-estimated 33 MPG combined.
• The Kia Carnival MPV with front-wheel drive gets an EPA-estimated 21 MPG combined.

While it’s evident that the Toyota Sienna gets better gas mileage than both Kia Carnival models, the powertrain edge goes to the Kia Carnival. Drivers appreciate the smooth-shifting six-speed and eight-speed automatic transmissions over any continuously variable automatic transmission, which can be loud and jerky, especially when accelerating on highways, and Atlanta has a lot of highways.

Interior Configurations and Comfort Features

Minivans differ from other vehicles thanks to the second-row seats. While passengers often compete to get the passenger seat in an SUV or car, most passengers want to sit in the posh captain’s chairs in the second row.

In both models, the upper-level trims have captains' chairs with heat, ventilation, and power adjustability. Kia designed the Carnival with easy in and out, which makes it especially easy to install car seats with the LATCH system.

The Toyota Sienna also has incredibly comfortable second- and third-row seats. The automaker makes it easy to get to the third row with tip-and-slide second-row movement. In the top trims, the Sienna second-row captain’s chairs have optional power-retractable leg rests.

Overall, the Kia Carnival has a more luxurious interior, especially when comparing the hard plastic features in the Toyota Sienna.
