Toyota Sienna vs Honda Odyssey: fuel economy and fuel cost
In model year 2026 the Toyota Sienna is the cheaper of the two to fuel: about $1,810 a year for its lowest-cost configuration (Sienna, 36 MPG combined), against $2,910 for the Honda Odyssey (Odyssey, 22 MPG combined). That is $1,100 a year, or $5,500 over five years.
One of the two is offered only with a hybrid or plug-in hybrid powertrain in this model year; the other has gasoline configurations. Costs assume 15,000 miles a year and the same fuel and electricity prices for both vehicles, using the EPA combined rating (55% city, 45% highway). Each figure is rounded to $10 and every difference is calculated from the rounded values.
The EPA is still publishing model year 2027 ratings, so this page compares model year 2026, the latest complete year.
