Tesla Model X vs. Rivian R1S vs. Kia EV9: Which Is The Ultimate Used 3-Row SUV?

If you need to move seven people without visiting a gas station, these are your "Big Three." The Rivian R1S is a trail-conquering tank, the Tesla Model X is the aerodynamic tech-leader, and the Kia EV9 is the new luxury standard that is making everyone rethink what a Kia can be. This is a battle of three distinct philosophies on how a family should travel.

Utility and Family Tech

We’re breaking down the third-row experience in each SUV—from the easy entry of the Model X’s Falcon Wing doors to the actual adult-sized legroom in the EV9. We also dive into the tech differences: Rivian’s new 4K cameras and "Autonomy Platform" vs. Tesla’s legendary software ecosystem vs. Kia’s ultra-fast 800V charging that gets a family back on the road in minutes. We'll look at trunk space with the seats up and down to see which one is the most practical for a weekend trip.

Andrew's Summary Take

If you crave off-road capabilities and raw power, the Rivian is hard to beat. Meanwhile, the Tesla Model X excels in range and charging experience. But the newest option, the Kia EV9, offers a great blend of luxury features and fast-charging tech.
