Sienna vs Odyssey (2026): Full Comparison

The minivan segment has shrunk, but the two survivors at the top are better than ever. The Toyota Sienna went all-hybrid in 2021 and has stayed that way, making fuel efficiency its core selling point. The Honda Odyssey sticks with a naturally aspirated V6 and focuses on raw hauling ability and a polished cabin. Choosing between them comes down to whether you prioritize fuel costs or outright power and refinement.

Performance

The Odyssey’s 3.5-liter V6 produces approximately 280 horsepower and 262 lb-ft of torque, paired with a 10-speed automatic. It accelerates to 60 mph in a projected 6.5 seconds — genuinely quick for a van carrying seven or eight passengers. Highway passing and merging feel confident, and the transmission finds the right gear without hunting.

The Sienna takes a fundamentally different approach. Its 2.5-liter four-cylinder works with two electric motors to produce a combined 245 horsepower through an electronically controlled CVT. The 0-60 time stretches to approximately 7.7 seconds, and full-throttle acceleration brings noticeable CVT drone. Where the Sienna wins decisively is at the pump: a projected 36 MPG combined versus the Odyssey’s 22 MPG. Over five years and 60,000 miles at $3.50 per gallon, that difference saves roughly $4,300 in fuel costs.

Both vans ride smoothly on suburban roads. The Odyssey edges ahead on highway composure — its independent rear suspension absorbs expansion joints and rough pavement more gracefully. The Sienna’s torsion-beam rear axle is competent but transmits more secondary harshness. Toyota does offer all-wheel drive on the Sienna, a significant advantage for families in snowy climates. The Odyssey remains front-wheel drive only.

Interior and Tech

Inside the Odyssey, the second-row Magic Slide seats move laterally and fore-aft, creating a wide center aisle or snugging up next to a child seat for easier access. The CabinWatch interior camera lets the driver monitor rear passengers on the infotainment screen, and CabinTalk pipes the driver’s voice through rear speakers so you do not have to shout directions to the third row.

The Sienna counters with an available ottoman-style second-row captain’s chair that reclines nearly flat — a feature borrowed from the Lexus LM. Its dashboard design is more modern, with a standard 9-inch touchscreen running Toyota’s Audio Multimedia system. Wireless Apple CarPlay and Android Auto come standard on both vans.

Third-row legroom is comparable at approximately 36 inches in both. The Odyssey’s third row folds completely flat into a floor well, creating a genuinely flat cargo floor. The Sienna’s third row also stows, but the mechanism is less seamless, and the resulting cargo floor sits slightly higher.

Material quality in the Odyssey leans toward soft-touch plastics and a well-damped feel at every touchpoint. The Sienna’s cabin uses durable but slightly harder materials, with contrast stitching and wood-tone trim on higher trims to compensate.

Safety

Both minivans hold projected IIHS Top Safety Pick+ ratings for 2026. Standard driver-assist suites are comprehensive on each.

Toyota Safety Sense 3.0 on the Sienna includes pre-collision braking with pedestrian and cyclist detection, adaptive cruise control, lane departure alert with steering assist, and automatic high beams. It adds a pre-collision system that can detect oncoming vehicles during left turns and intersections.

Honda Sensing on the Odyssey provides collision mitigation braking, road departure mitigation, adaptive cruise, lane keeping assist, and traffic sign recognition. Honda’s system also includes low-speed braking control that can detect pedestrians and cyclists when making turns.

Rear-seat reminders are standard on both, as required by recent regulation. Blind-spot monitoring with rear cross-traffic alert is standard on mid-trim and above for both vans.

Value and Cost of Ownership

The Sienna starts approximately $1,500 lower than the Odyssey and delivers dramatically better fuel economy. Five-year total fuel savings alone can offset the price of a trim upgrade. Toyota’s hybrid powertrain has a strong reliability track record, and the Sienna consistently ranks among the most dependable minivans in J.D. Power and Consumer Reports surveys.

The Odyssey commands a slightly higher purchase price but holds resale value exceptionally well — projected three-year residual values hover around 62 percent, versus approximately 59 percent for the Sienna. Insurance costs are comparable, with both averaging around $1,600 to $1,800 annually for a 35-year-old driver with clean history.

Maintenance costs are similar for the first 60,000 miles. The Sienna’s hybrid battery is covered by an 8-year/100,000-mile warranty, and real-world failure rates on Toyota’s hybrid system remain very low.

Verdict

Choose the Sienna if fuel economy is your top priority, if you live in a region that demands AWD, or if you want the lowest cost of entry. Its hybrid system pays for itself in fuel savings and asks for no compromise in passenger space.

Choose the Odyssey if you value powertrain refinement, a flat-folding cargo floor, and the Magic Slide second row. The V6 makes highway driving and towing small trailers (up to 3,500 pounds) more relaxed, and the interior feels a half-step more premium.

For most families, the Sienna’s fuel savings and available AWD give it a slight overall edge — but neither choice is a wrong one.

Key Takeaways

The Sienna is hybrid-only with a projected 36 MPG combined; the Odyssey uses a V6 at approximately 22 MPG.
The Odyssey’s Magic Slide seats and flat-folding third row offer superior cargo flexibility.
The Sienna is the only minivan available with all-wheel drive.
Both earn projected IIHS Top Safety Pick+ ratings and include comprehensive driver-assist suites.
Five-year fuel savings on the Sienna can exceed $4,000 compared to the Odyssey.
