2026 Mercedes-Benz GLS vs Lexus TX: Two Philosophies of Three-Row Luxury for Atlanta Families
By the Mercedes-Benz of Atlanta Northeast Team | Updated June 2026
The Lexus TX is one of the newest and fastest-growing three-row luxury SUVs on the market. It is well-built, efficient, and genuinely roomy.
The Mercedes-Benz GLS is the brand's flagship SUV. Available V8 and AMG power. Standard AIRMATIC air suspension. 7,700 pounds of towing capacity.
These vehicles answer the same question in fundamentally different ways. The TX is about accessible, serene luxury. The GLS is about flagship-level capability and presence.
The question is less about which is better and more about what your family wants from a luxury three-row.
This guide from Mercedes-Benz of Atlanta Northeast in Duluth breaks down the differences for families across Sugarloaf, Hamilton Mill, Berkeley Lake, and the Lake Lanier corridor.
What to Know in 30 Seconds
- The GLS leads on capability: Available 4.0L V8 (510 hp), AMG GLS 63 (603 hp), and 7,700 lbs of towing capacity according to Mercedes-Benz
- The GLS leads on ride sophistication: AIRMATIC air suspension is standard across the lineup
- The TX leads on cargo volume: Up to roughly 97 cubic feet with all seats folded, versus 84.7 in the GLS
- The TX leads on hybrid options: A TX 500h hybrid and TX 550h+ plug-in hybrid are part of the lineup
- Different philosophies: Mercedes-Benz emphasizes statement, presence, and flagship engineering. Lexus emphasizes serenity, efficiency, and approachable luxury

The Lexus TX in Context: Why It Got So Popular
Lexus arrived late to the three-row luxury party, and took meaningful market share with a smart formula.
The TX entered the market for 2024 and resonated quickly with families looking for a three-row luxury SUV that is neither a body-on-frame truck like the GX nor a midsize like the RX. Three reasons it works:
- Real adult-usable third row with 33.5 inches of legroom according to Lexus
- Hybrid choices including the TX 500h F SPORT and the TX 550h+ plug-in hybrid with approximately 33 miles of electric range
- Lexus serenity: a quiet cabin, soft-touch materials, and the brand's reputation for low-stress ownership
The TX deserves the consideration it gets. The conversation gets interesting when families ask what they are giving up to choose it.
The TX competes well on space and efficiency. The GLS competes on a different axis: flagship engineering, available V8 power, and air suspension. The right answer depends on which axis matters more to your family.
Ride and Suspension: The Air Suspension Difference on Georgia Roads
Pleasant Hill Road has frost heaves. I-985 has expansion joints. Highway 400 has potholes. This is where the GLS pulls away.
The 2026 GLS comes standard with AIRMATIC air suspension across every trim. According to Mercedes-Benz, this system continuously adjusts ride height and damping based on road conditions and driving style.
The available E-Active Body Control on higher trims uses cameras to scan the road ahead and pre-emptively adjust suspension at each wheel.
The TX uses conventional steel-spring suspension on most trims, with Adaptive Variable Suspension available on the TX 500h F SPORT Performance. The TX rides well by any objective measure.
But there is a noticeable difference between well-tuned conventional suspension and air suspension that adapts to every input in real time.
Where you feel the difference:
- Long highway runs to the North Georgia mountains: AIRMATIC lowers the GLS at speed for stability and raises it for clearance on rough access roads
- Loaded weekend trips to Lake Lanier: air suspension self-levels regardless of passenger and cargo weight
- Rough patches on Sugarloaf Parkway or Hamilton Mill area roads: AIRMATIC absorbs imperfections that send a slight thump through the TX's cabin
For a family that uses the SUV on long trips, on imperfect roads, or with significant cargo, the air suspension is a real every-drive advantage.
Power and Towing: Where the GLS Plays in a Different League
The GLS reaches V8 and AMG territory. The TX maxes out at a V6 plug-in hybrid.
The GLS lineup runs from a refined 3.0L inline-six in the GLS 450 (375 hp), to a 4.0L twin-turbo V8 in the GLS 580 (510 hp), to the handcrafted AMG GLS 63 (603 hp). According to Mercedes-Benz, the GLS 580 reaches 60 mph in around 4.7 seconds.
The TX tops out at 404 hp from a 3.5L V6 plug-in hybrid (TX 550h+). It is quick and refined, but not a V8, and there is no true high-performance variant.
The gap is more meaningful on towing capacity:
- Mercedes-Benz GLS: 7,700 lbs when properly equipped according to Mercedes-Benz, the same across GLS 450, GLS 580, and AMG GLS 63
- Lexus TX 350 and TX 500h: 5,000 lbs when properly equipped according to Lexus
- Lexus TX 550h+: Towing is not recommended on the plug-in hybrid per Lexus
For a family in the Berkeley Lake or Lake Lanier area who tows a boat, ski boat trailer, or horse trailer, the GLS's 2,700-pound advantage is the difference between "can do it" and "should not do it."
The GLS towing capacity is 54% higher than the TX. If you have a boat at Lake Lanier or you are eyeing one, this number does the choosing for you.
Third Row and Cargo: An Honest Look
The TX wins raw cargo volume. The GLS wins on third-row experience and premium passenger features.
This is where the comparison becomes most nuanced. The TX genuinely has more cargo space:
- Behind the third row: TX has 20.2 cu ft vs GLS's 17.4 cu ft
- All seats folded: TX has approximately 97 cu ft vs GLS's 84.7 cu ft
- Third row legroom: TX offers 33.5 inches, competitive in the segment
If raw hauling volume is the deciding factor, the TX has the edge. That is honest.
What the GLS offers in exchange is a more premium passenger experience:
- Power-folding third row operated from inside the cargo area
- Available heated third-row seats for cold morning carpools
- Available four-zone climate control so passengers in every row set their own temperature
- Available second-row captain's chairs with massage in the six-passenger configuration
- AIRMATIC self-leveling keeps the cabin level even when fully loaded
Maximum cargo volume on a Costco run, or a more sophisticated travel experience for the people inside.
Interior Philosophy: Statement vs Serenity
Two different ideas of what luxury feels like.
Sit in the GLS and you encounter dual 12.3-inch widescreen displays running MBUX, intricate woodwork, and optional MANUFAKTUR materials that allow custom interior configurations. The cabin makes a statement: this is a flagship.
Sit in the TX and you encounter Lexus's distinct take: a 14-inch touchscreen, clean horizontal lines, restrained materials, and a sense of calm.
Neither is objectively better. They serve different sensibilities:
- The GLS speaks Italian leather and architectural drama. It signals achievement.
- The TX speaks Japanese craftsmanship and quiet sophistication. It signals discernment.
For a family that values the prestige of arriving in a flagship-grade vehicle, at a school event, a Chateau Elan dinner, or a business gathering, the GLS communicates differently.
Real Atlanta Family Scenarios
Where these two SUVs actually live their lives.
Saturday morning at Lake Lanier with the boat. The GLS hooks up to a 23-foot ski boat and pulls it from Hamilton Mill to the Lake Lanier ramp without strain. The TX 350 or TX 500h can handle a smaller boat or jet ski trailer, but the 5,000-lb limit takes a family wakeboard boat off the table.
School run on Sugarloaf Parkway. Both work well. The TX's tight turning circle shines in the carpool line. The GLS's commanding presence and power-folding third row earn appreciative looks.
Family trip to the Blue Ridge Mountains. The GLS's AIRMATIC suspension absorbs imperfect mountain roads with composure. Four-zone climate keeps everyone comfortable across all three rows. The TX handles the trip well but lacks the air suspension's adaptive ride quality on rough stretches.
Sunday dinner at Chateau Elan. Either makes a statement. The GLS communicates flagship status; the TX communicates understated contemporary luxury.

| Maximum cargo volume drives your purchase decision | TX | ~97 cu ft total vs 84.7 in the GLS |
| You want a plug-in hybrid with electric range | TX | TX 550h+ offers ~33 miles of EV range |
| Quiet, understated luxury matches your taste | Either | Different expressions of luxury, both delivered well |
