How Does the Kia Sorento Compare to the Competition?

The 2021 Kia Sorento is a decent midsize SUV since it has a lot of technology features and a long warranty, which helps it earn our recommendation for shoppers.

The Hyundai Santa Fe is another midsize SUV, which costs about $1,500 more. Both the Hyundai Santa Fe and Kia Sorento are built on the same platform, but the Hyundai Santa Fe offers a higher-quality interior. We recommend the Hyundai Santa Fe since the extra features are worth the money, but it’s worth testing both to see which fits you better.

The Kia Telluride is a larger SUV, which costs about $4,000 more. Passenger room is better in the Kia Telluride, while the Kia Sorento offers a smoother suspension at highway speeds. We recommend the Kia Telluride since it’s a more capable midsize SUV, making it worth the extra money.
