I was actually surprised when I looked at what the current Siennas get. I have a friend with a, now, quite old Sienna who was really surprised at how high the mileage of my relatively new Honda Passport was. And the current hybrid Sienna is a fair bit better.
> The current Toyota Sienna … gas mileage.
Better mileage and optional all wheel drive were the only things I preferred about the Sienna. But while I don’t like the mileage the Odyssey gets, I also don’t actually drive far very often so it doesn’t matter much. I put less than 10k miles on my car every year.
