2026 Buick Enclave vs 2027 Mercedes-Benz GLS

Heavily updated for the 2025 model year, the Enclave three-row crossover SUV enters 2026 unchanged. It shares a platform with the Chevrolet Traverse and GMC Acadia, carving out its own niche with a greater emphasis on luxury and comfort than ruggedness and active-lifestyle pretensions.

Verdict: The 2026 Buick Enclave finds a middle ground between standard three-row SUVs and their more expensive luxury-branded counterparts. While it's not particularly exciting to look at or drive, it gets the fundamentals right with a spacious cabin in all three rows, a large cargo capacity, high levels of comfort, and easy-to-use tech.

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.
