Honda Odyssey vs. Toyota Sienna [2027 Guide]

Choosing a minivan is less about finding the flashiest vehicle and more about finding one that makes everyday family life easier. That means comfortable seating, useful cargo space, easy access to the third row, practical technology and enough flexibility to handle everything from school drop-offs to long road trips.

Two of the most established choices are the Honda Odyssey and Toyota Sienna. For this comparison, we’re looking at the 2027 Honda Odyssey against the Toyota Sienna.

Both minivans offer three rows, sliding rear doors and family-focused technology. However, they take different approaches to powertrains and interior versatility.

For many families, the 2027 Honda Odyssey stands out for its powerful V6 engine, flexible Magic Slide® second-row seating, spacious cabin and family-friendly technology. The Sienna counters with standard hybrid power and available all-wheel drive.

Here’s how the two compare.

Honda Odyssey vs. Toyota Sienna: Quick Comparison

Specifications and features vary by trim.

Performance: Odyssey’s V6 vs. Sienna’s Hybrid

The biggest difference between these two minivans is under the hood.

The 2027 Honda Odyssey uses a 3.5-liter V6 engine producing 280 horsepower, paired with a 10-speed automatic transmission. That gives the Odyssey a substantial power advantage over the Sienna’s hybrid powertrain, which produces 245 combined horsepower. 

Toyota takes a different route. Every 2026 Sienna uses a 2.5-liter four-cylinder hybrid powertrain, pairing the gas engine with electric motors. It’s an appealing setup for families who put fuel efficiency near the top of their list. 

The choice ultimately comes down to what you value.

The Odyssey’s V6 provides strong, straightforward performance that’s particularly useful when you’re carrying a full cabin of passengers, luggage or both. The Sienna’s hybrid system prioritizes efficiency and offers an alternative for drivers who’d rather maximize fuel economy.

Fuel Economy: Sienna Has the Hybrid Advantage

There’s no way around it: the Toyota Sienna has the advantage when it comes to fuel economy.

Because the 2026 Sienna comes standard with a hybrid powertrain, Toyota positions it as an efficiency-focused alternative in the minivan segment. Toyota lists the Sienna at up to 36 city/36 highway MPG, depending on configuration. 

The 2027 Odyssey uses a conventional V6, so it can’t match those hybrid fuel-economy numbers.

That’s an important consideration for families who drive significant mileage every year. If minimizing fuel stops is your top priority, the Sienna deserves serious consideration.

For shoppers who place greater emphasis on acceleration, conventional power delivery and the versatility of the Odyssey’s cabin, however, Honda’s approach has plenty going for it.

Interior Space: Where the Odyssey Really Shines

A minivan’s interior needs to work harder than almost any other passenger vehicle. Kids, adults, car seats, backpacks, groceries, sports equipment and luggage can all compete for the same space.

The 2027 Honda Odyssey offers up to 158 cubic feet of cargo volume, giving it a significant advantage in maximum cargo capacity.

But raw cargo volume isn’t the only reason the Odyssey is useful.

Honda’s Magic Slide® second-row seats can be configured in multiple ways to make it easier to access the third row, separate passengers or create additional flexibility between the seats. Depending on configuration, the second row can also be removed when you need maximum cargo capacity.

The 2026 Sienna offers its own clever second-row design with Super Long Slide second-row seats. Certain configurations also allow the second-row seats to fold or slide forward to accommodate cargo.

Both are practical. However, the Odyssey’s Magic Slide seating gives families a particularly useful way to adapt the cabin around passengers.

Which Minivan Has Better Family Technology?

Modern minivans aren’t just transportation. They’re mobile family rooms.

The 2027 Odyssey comes standard with a 9-inch color touchscreen, wireless Apple CarPlay® and wireless Android Auto™. Available features include a wireless phone charger, Wi-Fi hotspot capability and a rear entertainment system with a 12.8-inch display.

The Odyssey also offers Honda’s CabinWatch® system, which can give the driver a view of rear passengers through the center display. CabinTalk® can also help the driver communicate with passengers in the second and third rows.

Toyota’s Sienna is similarly focused on connectivity, offering a 9-inch touchscreen, wireless Apple CarPlay® and wireless Android Auto™. Available features include a rear-seat entertainment system, 12-speaker JBL® audio and a 7-inch color multi-information display. 

Both are well-equipped family vehicles, but the Odyssey’s combination of passenger-monitoring and communication features gives it an edge for parents who frequently have a full cabin.

Safety Features for Family Driving

Both minivans include extensive driver-assistance technology.

The 2027 Odyssey comes standard with Honda Sensing®, which includes technologies such as Collision Mitigation Braking System™, Adaptive Cruise Control with Low-Speed Follow, Lane Keeping Assist System and Road Departure Mitigation System. 

The 2026 Sienna includes Toyota Safety Sense™ 2.0, with features such as Pre-Collision System with Pedestrian Detection, Full-Speed Range Dynamic Radar Cruise Control, Lane Departure Alert with Steering Assist and Lane Tracing Assist. 

Both provide a strong collection of standard safety technology. The best way to compare them is to experience each system firsthand and consider which controls and alerts feel most intuitive to you.

Honda Odyssey vs. Toyota Sienna: Which Is Better?

Both minivans have legitimate strengths, so your priorities should drive the decision.

The 2027 Honda Odyssey may be the better choice if you want:

• A powerful 280-horsepower V6

• Up to 158 cubic feet of maximum cargo volume

• Flexible Magic Slide® second-row seating

• Family-focused features such as CabinWatch® and CabinTalk®

• Available rear entertainment technology

• Wireless smartphone connectivity

• A conventional powertrain rather than a hybrid system

The 2026 Toyota Sienna may be the better fit if you prioritize:

• Standard hybrid power

• Available all-wheel drive

For many families, the Honda Odyssey offers the more compelling combination of performance, passenger flexibility and family-oriented technology. The Sienna’s hybrid efficiency and available AWD are significant advantages, but the Odyssey’s powerful V6 and highly adaptable interior make it particularly well-rounded for everyday family life.
