Mercedes-Benz GLS vs Kia EV9

The full-size, three-row GLS is for anyone who needs extra space and towing capacity in their luxury SUV. Mercedes also considers the GLS to be the SUV equivalent of its flagship S-Class sedan, so it can be equipped with virtually every feature in the automaker’s catalog. For 2027, the GLS receives updated styling, powertrains, and tech features. Its competition includes the BMW X7, the Cadillac Escalade, the Land Rover Range Rover, the Lexus LX, the Lincoln Navigator, and the all-new Audi Q9.

Verdict: The extensive updates don’t make as much difference as expected from behind the wheel, but that’s okay because the GLS was already a well-executed luxury SUV.

Kia’s three-row electric SUV is available in single- or dual-motor configurations with up to 305 miles of range, recharges fast, and is compatible with Tesla Superchargers. Upgrades for 2026 include a longer range, a Nightfall Edition package, fresh colors, and a new Terrain driving mode.

Verdict: The 2026 Kia EV9 offers usable driving range and fast recharging times in a powerful, innovative, and practical midsize three-row electric SUV. Roomy, comfortable, safe, and well-equipped, the 2026 EV9 is a terrific, technologically advanced EV.
