2021 Sienna vs. Sedona Comparison

Minivans feature ample passenger and cargo space, enough safety features to add peace of mind, and the interior convenience features to make everyone in the family happy.

The Sienna made its debut in 1998 as the first American-assembled van for Toyota. In 2021, with the Sienna, you get all of that plus an impressive hybrid drivetrain and available All-Wheel Drive (AWD) capability. The Sedona was introduced in 2002 by Kia as their amenity-loaded family vehicle.

For any new car buyer safety is a top consideration. Every grade of the all-new 2021 Sienna comes with Toyota Safety Sense 2.0 (TSS 2.0). Kia's own comparable suite of active safety features (Kia Drive Wise) doesn't come standard on the base-grade Sedona LX.

When it comes to picking a vehicle fit for your lifestyle, it's important to consider specifications in safety, performance, and interior features. Let's take a look at the Sienna vs. Sedona to see which is ideal for you.
