While Mercedes-Benz offers several impressive SUVs, they serve different needs and size preferences.
The GLE is a midsize SUV with available third-row seating, but it’s noticeably smaller than the GLS. Drivers who need maximum passenger and cargo space typically prefer the GLS.
The iconic G-Class has a bold, upright design and off-road capability, but it is not the largest Mercedes-Benz SUV by interior volume. The GLS offers more usable space and a more family-friendly layout.
For those seeking the ultimate expression of luxury, the Mercedes-Maybach GLS builds upon the GLS platform with exclusive materials, enhanced rear-seat comfort, and ultra-premium finishes—while still maintaining the same full-size SUV proportions.
The GLS is ideal if you want:
A full-size luxury SUV with real third-row comfort
A refined alternative to large American SUVs
Advanced safety, infotainment, and driver-assist features
A prestigious vehicle that balances power and sophistication
Whether you’re carpooling, traveling, or commuting in style, the GLS delivers space and elegance in equal measure.
