As the 2026 Mercedes-Benz SUV with the most passenger space, the Mercedes-Benz GLS is the only vehicle in our lineup that comes standard with three-row, seven-passenger seating. By default, the second row is a three-person bench seat with power-folding technology to simplify access to the third row. An available six-passenger configuration can be chosen without additional cost, which gives you two second-row captain's chairs with individualized adjustments and armrests.
Size is a highlight of the GLS. As the largest Mercedes-Benz SUV, it gets up to 84.7 cubic feet of cargo capacity with all rear seats folded – perfect for large grocery hauls, two-person road trips, and much more. It is 205 inches in length and 79.9 inches in width without mirrors; you and your family get the room to stretch and the presence to command the road. In terms of performance, the GLS runs with a 375-horsepower powertrain. However, a V-8 is also available, delivering a robust 510 horsepower and a 4.7-second 0-60 mph time.
The Mercedes-Benz GLE is a midsize option within the collection of Mercedes-Benz SUVs with third-row seating. This 194.3-inch-long model is standard with seating for five people but offers an add-on package for its seven-seater configuration. Along with a third row, this package boasts power-sliding and folding second-row seats and two USB-C ports for your third-row passengers.
Specific third-row measurements have not been released by Mercedes-Benz as of this writing. However, what we do know is that up to 74.9 cubic feet of cargo capacity is available behind the front row. This SUV comes standard with heated front seats, a power tilt/slide sunroof, and aluminum roof rails. A 381-horsepower plug-in hybrid variant is available, but it does not offer the available three-row package. Meanwhile, the gasoline-powered 2026 GLE has an output that starts at 255 horsepower and goes all the way up to 510 horsepower, depending on the configuration.
Flexibility is at the core of the 2026 Mercedes-Benz GLB. Similar to the GLE, the GLB comes standard with five-passenger seating but offers the choice for a third row. When equipped with a third row, the passenger capacity rises to seven, complemented by EASY ENTRY® second-row seating that can slide an additional 5 inches for simpler third-row access.
An illuminated entry system, power liftgate, and power front seats with memory are standard, while high-quality amenities like 64-color LED ambient lighting, heated front seats, and leather upholstery are available. The second row integrates a 40/20/40 split-fold function, and the available third row boasts a 50/50 split-fold feature. In terms of performance, the 2026 GLB comes standard with a 221-horsepower 2.0-liter inline-4 engine with mild-hybrid drive for an efficient experience.
There are even a couple of electric Mercedes-Benz SUVs with third-row seating available. The EQS SUV from Mercedes-Benz offers exceptional standard features, including four-zone automatic climate control, heated and ventilated front seats, and leather upholstery. While seating for five is standard, you can add the optional third row for a seven-passenger layout. With it equipped, the second row can move forward to grant easier entry to the third row.
Thanks to the standard 355-horsepower motor that gets you to 60 mph in just 5.9 seconds, every drive with your family will feel fun and exciting in the EQS SUV. The available powertrain renders 536 horsepower and an even quicker 4.6-second 0-60 mph run. Discover the full list of features and specs of the new EQS SUV from Mercedes-Benz today.
Finally, the EQB from Mercedes-Benz can be configured to a three-row SUV design; it's a five-passenger layout by default. At this time, there is no confirmation from the brand that there will be a 2026 model; however, ample comforts and conveniences are offered in the 2025 EQB, including power-adjustable front seats with three-position memory, MB-Tex upholstery, a 10.25-inch touchscreen, and pre-entry climate control. Like the previous models, the EQB SUV's second row can slide forward, helping passengers get into the back row more gracefully.
Behind the wheel, the EQB favors an easy-to-handle drive. The standard 188-horsepower front-mounted electric motor provides an impressive all-electric range for an urban commuter. Opt for the dual-motor setup, and the EQB delivers 288 horsepower. Meanwhile, its 184.4-inch length and 72.2-inch width (without mirrors) make parking, navigating intersections, and more easier. You can enjoy up to 61.8 cubic feet of storage space with the rear rows down, too.

There are currently four 2026 Mercedes-Benz SUV models with three rows as standard or available: the GLS, GLE, GLB, and EQS. There is no official 2026 EQB just yet, but the 2025 iteration is available. The GLS is the only one that comes standard with a third row; all other variants comprise a five-passenger cabin and provide a third row for seven occupants as an option.
The 2026 Mercedes-Benz GLE offers available third-row seating. It is a five-passenger midsize SUV by default, boasting an available add-on package for a third row. With this package equipped, the GLE sports two USB-C ports in the third row and power-sliding and folding second-row seats. Discover the full dimensions of the 2026 GLE at our Mercedes-Benz dealership.
Generally, Mercedes-Benz vehicles with a third row have a passenger capacity of seven: two in the front, three in the middle, and two in the back. However, the GLS can access a six-seater configuration with two second-row captain's chairs. This makes it easier to get to the rear of the vehicle while providing individualized chair adjustments and armrests for the second-row passengers.
Third-row seating is standard or optional in most Mercedes-Benz SUVs, depending on the model. The GLS is the only Mercedes-Benz SUV that comes standard with three rows; it is also the only SUV with a six-passenger configuration available in place of its standard seven-occupant layout. The remaining SUVs – GLE, GLB, EQS, and EQB – offer a third row as an add-on.
