Welcome to the most fuel-efficient people mover you can buy today. Our week-long test of the 2026 Toyota Sienna resulted in an average of 34 MPG! That is a real-world combination of city crawling, highway cruising, soul-crushing traffic, and idling in school pickup lines. For a 4,700-pound, 17-foot-long, 8-passenger vehicle, that is practically a work of science fiction. Somehow, the masters of the hybrid at Toyota have turned efficiency into a literal science.
There is no other vehicle on the market today—or frankly, even yesterday—that can touch the combination of high efficiency and cavernous space that the 2026 Sienna provides. To prove the point, here is a list of the Sienna’s closest competitors across both the minivan and crossover segments, along with their average combined MPG:
Honda Odyssey: 22 MPG
Kia Carnival (Hybrid): 32 MPG
Chrysler Pacifica (Gas): 22 MPG
Chrysler Pacifica (Hybrid): 30 MPG (Discontinued)
Volkswagen Atlas: 23 MPG
Toyota Grand Highlander (Hybrid): 33 MPG
Chevrolet Traverse: 23 MPG
As you can see, the only vehicle that even hangs in the same zip code is the Sienna’s stablemate, the Grand Highlander. For all intents and purposes, the Grand Highlander is just a Sienna without sliding doors. If your primary mission is moving human beings, losing those doors makes it a bit more of a pain in the ass to get people in and out, but hey—it’s hard to argue with the "cool factor" of a crossover if you’re looking at it from a purely egotistical viewpoint. But at the very least, the Grand Highlander almost matches the fuel efficiency of the Sienna.
Living Large: Space and Equipment
But let’s talk about why you’d actually choose the Sienna over a crossover. Step inside, and it’s an architectural marvel. The "Super-Long-Slide" second-row captain's chairs offer more legroom than a first-class airline seat, complete with fold-out leg rests. You can look on in envy as your children relax in supreme comfort while you’re stuck in traffic. For the 2026 model year, the updated infotainment system is finally snappy, wireless, and gorgeous. You also get a built-in vacuum, a FridgeBox that stays outstandingly cold, and enough USB-C ports to power a small village. While crossovers feel "full" the moment you load more than three people, the Sienna can fill every available seat without a care in the world.
Performance: Smooth, Not Sporty
The 2026 model feels more refined than ever; the transition between electric and gas power is nearly invisible. If it wasn’t for the audible hum of the gas engine starting up, you’d never even know it was on, thanks to its quiet and composed behavior. AWD is there to help when things get slippery, and while I wouldn’t take this thing on any mountain runs, it doesn’t fully disappoint in the corners, either. Yes, it’s slow to 60, and highway passing brings the drone of the CVT to full tilt, but other than that… I honestly have no complaints.
The Literal Elephant in the Room: Full-Size SUVs
Now, the list above includes the Sienna’s "closest" competitors in terms of price. But let’s be honest: if you have some more coin to spend, you might be tempted by something even bigger. This leads you down the path of the most purely "Murikan" option to move people: the Full-Size SUV.
Chevrolet Suburban: 17 MPG
Ford Expedition XL: 19 MPG
Toyota Sequoia: 20 MPG
Nissan Armada: 16 MPG
Jeep Grand Wagoneer: 17 MPG
In the most "no duh" way possible, the 2026 Toyota Sienna demolishes these rolling behemoths in fuel efficiency. The real reason I bring them up? Thanks to the Orange McDumbdum in office, fuel prices are soaring above $4.00 a gallon. And that’s not even the real number—the majority of those big SUVs require Premium fuel, which is now pushing $5.00 a gallon in most states.
Final Thoughts
So, while your ego might be screaming for a Full-Size SUV or a rugged Crossover, your bank account is dragging you back down to reality. When you factor in the cost of a cross-country road trip or even just a month of suburban commuting, you realize there is only one real alternative for moving a family without going broke.
