Toyota Sienna Specs, Engines & Dimensions (2017–2021) — Third Generation Restyling 2
The Toyota Sienna Third Generation Restyling 2 is the minivan you use for school runs and long family trips, with gasoline power and an automatic gearbox in a practical people-mover body.
One Toyota Sienna engine example in this restyling is the 3.5 AT minivan: a 3.5-liter gasoline powertrain with an automatic transmission. All-wheel drive is part of that setup, so you keep a simple automatic gearbox while the drivetrain can put power to more than two wheels when traction drops.
