The large-luxury-SUV field just gained a useful new data point. Car and Driver has driven the updated 2027 Mercedes-Benz GLS and GLE, and the GLS changes map unusually well to a buyer who wants genuine third-row room, high-end technology, serious acceleration and a comfortable ride. This is not merely a new grille. The refresh brings an S-Class-inspired three-display Superscreen layout, revised controls, a newer electrical architecture and chassis work intended to make the big SUV feel more composed.
The GLS 580 keeps the V8 proposition but adopts a flat-plane-crank design related to the updated S-Class powertrain. Mercedes has also revised the inline-six GLS 450. The most relevant part for everyday ownership may be the suspension: available E-Active Body Control and predictive damping are designed to smooth bumps and manage body movement. These are precisely the things a short test drive on a perfect road can conceal; seek out patched city pavement and highway expansion joints.
Car and Driver lists the updated GLS starting around $95,500, but the meaningful comparison is not the base sticker. Compare a properly equipped GLS 580 against the BMW X7 M60i and Cadillac Escalade-V or other performance-oriented full-size luxury SUVs. Check second-row captain’s-chair availability and the resulting walk-through to the third row, real luggage space behind occupied third-row seats, road noise, seat comfort and driver-assistance behavior. The third row is not useful merely because the brochure says seven seats.
The trade-off is familiar: the GLS prioritizes refinement and cabin comfort more than an overtly sporting character. That may be exactly the point. Do not assume the flat-plane V8 makes it the quickest option or that every high-tech feature is standard; verify trim and option availability for the U.S. market before deciding.
Do this: put a 2027 GLS 580 on the shortlist and arrange a back-to-back, same-route comparison with the X7 M60i once local dealer demonstrators are available. The suspension and captain’s-chair ergonomics should decide more than the screen count.
