Mercedes-Benz GLS vs Toyota Grand Highlander

It could be said that the Mercedes GLS is the S-Class of SUVs, but that’s not entirely accurate. The S-Class sedan commands a significant premium over the GLS, while the legendary G-Class SUV is even more expensive than the S-Class. Nevertheless, for buyers who want a three-row SUV with a three-pointed star on its grille, the 2026 Mercedes-Benz GLS is the right choice because it offers more passenger room and cargo space than any other model in the automaker’s lineup.

Verdict: Large, luxury SUVs are a lot more expensive than they used to be, and while the 2026 Mercedes GLS can’t match them for sheer size and capability, its manageable dimensions, undeniable comfort, refinement, and rewarding driving dynamics make a strong case.

Summary: Toyota offers a total of four SUVs with three rows of seats, so it might be tough to decide which one is right for you and your family. While the adventurous will likely gravitate to the 4Runner or Sequoia, those who enjoy soccer games and Target runs should stick to the Highlander or Grand Highlander. Both are excellent choices, but if you’ve got bigger kids with more gear, then the 2026 Toyota Grand Highlander should be on your shortlist.

The Grand Highlander was introduced for the 2024 model year and enters 2026 unchanged. In addition to good fuel economy and lots of power, it provides plenty of space for cargo and people—even in the third row. However, the exterior styling feels stale and some of the infotainment features require a subscription.

Verdict: Despite a few small foibles, the 2026 Toyota Grand Highlander is perfect for active families who need a bit of extra space and comfort.
