The 2026 Toyota Sienna occupies the minivan segment with a boxy body, sliding side doors, three rows of seating accommodating up to eight passengers, and cargo space that expands when rear seats fold or stow. Buyers compare it to the Honda Odyssey, Chrysler Pacifica with its plug-in hybrid variant, and Kia Carnival offering an SUV-like design and extended warranty. This model carries over the platform from the 2021 redesign while maintaining a hybrid-only powertrain consisting of a 2.5-liter four-cylinder engine paired with electric motors for 245 total system horsepower. Power routes through an electronically controlled continuously variable transmission with front-wheel drive as standard and all-wheel drive available for improved traction.

The Toyota Audio Multimedia infotainment includes an 8-inch touchscreen on the LE trim and 12.3 inches on XLE and above, supporting wireless Apple CarPlay, Android Auto, over-the-air mapping updates, and subscription cloud-based navigation. Updates for 2026 make features like dual power-sliding side doors, power liftgate, rear window shades, an 8-speaker audio system, and windshield wiper de-icer standard on the LE trim, complemented by the Toyota Safety Sense 2.0 suite with adaptive cruise control, lane tracing assist, and pedestrian detection. Integration with the Toyota app enables Remote Connect for functions such as remote start, lock/unlock, and vehicle status checks, alongside over-the-air software updates for the infotainment system and trial subscriptions for services like navigation assistance.
