I was impressed by the milage I get on this vehicle: around 10.7L/100km in the city and around 9L/100km on the highway. Driving with A/C on adds at least one liter per 100km see full Toyota Sienna review

It is fair for a minivan, but the RAV4 gets significantly better mileage because it is built on the Camry chassis. see full Toyota Sienna review
