Toyota Sienna vs. Honda Odyssey: What Bay Area Families Should Expect When Shopping in 2026

Quick answer: The 2026 Toyota Sienna is the more efficient minivan (hybrid-only, about 35–36 mpg combined) but the harder one to buy, with low supply and occasional dealer markups. The 2026 Honda Odyssey uses more fuel (a V6 rated 22 mpg combined) but is far easier to find and gives Bay Area buyers real negotiating room.

What is it like shopping for a Sienna vs. an Odyssey?

Which minivan should you choose?
