2026 Lexus LX vs. Mercedes-Benz GLS vs. BMW X7
Three full-size luxury SUVs, three very different engineering philosophies. The 2026 Lexus LX is body-on-frame with a locking center differential and low-range gearing. The 2026 Mercedes-Benz GLS and 2026 BMW X7 are unibody SUVs tuned for on-road refinement and speed. Each wins categories outright, and drivers from Tarzana to Encino ask us to break down the differences honestly. This comparison covers all three across pricing, powertrain, capability, space, technology, safety and warranty, using gas-powered models only.

MSRP excludes taxes, title, license and dealer installed options, accessories, fees and charges. MSRP is not the dealer advertised price. Dealer price will vary. The dealer sets the final price.
- Lexus LX enters highest and finishes lowest, across the narrowest band of the three. A hybrid LX 700h range is also offered and falls outside the scope of this comparison.
- Mercedes-Benz GLS undercuts the LX at entry, then climbs well past it at the top. A Maybach GLS 600 sits above the three gas models covered here.
- BMW X7 starts lowest of the three and tops out highest, with the ALPINA XB7 the most expensive vehicle in this comparison.
BMW X7 vs. Lexus LX vs. Mercedes-Benz GLS: Engines and Acceleration
| Specification | 2026 Lexus LX | 2026 Mercedes-Benz GLS | 2026 BMW X7 |
|---|---|---|---|
| Entry engine | 3.4L twin-turbo V6 — 409 hp / 479 lb-ft | 3.0L turbo I6 mild hybrid — 375 hp / 369 lb-ft | 3.0L TwinPower Turbo I6, 48V — 375 hp / 398 lb-ft |
| Mid engine | Same 3.4L V6 across all gas trims | 4.0L biturbo V8 mild hybrid — 510 hp / 538 lb-ft | 4.4L M TwinPower Turbo V8, 48V — 523 hp / 553 lb-ft |
| Top engine | Same 3.4L V6 across all gas trims | AMG 4.0L V8 biturbo — 603 hp / 627 lb-ft | 4.4L twin-turbo V8, ALPINA — 631 hp / 590 lb-ft |
| Transmission | 10-speed Direct Shift automatic | 9-speed automatic | 8-speed automatic |
| Drivetrain | Full-time four-wheel drive, Torsen locking center differential | 4MATIC all-wheel drive | xDrive all-wheel drive |
| 0–60 mph, entry model | 6.9 sec | 5.8 sec | 5.6 sec |
| 0–60 mph, top model | 6.9 sec | 4.1 sec | 4.0 sec |
The Lexus LX takes a different approach: one engine, one tune, across all three gas trims, with no V8 upgrade path. The Mercedes-Benz GLS and BMW X7 both ladder from a 375-horsepower six to a V8 north of 600 horsepower, and both reach 60 mph in about four seconds at the top. If straight-line speed decides this for you, the LX is the slowest at any price.
Lexus LX vs. GLS vs. X7: Towing and All-Terrain Capability
| Specification | 2026 Lexus LX | 2026 Mercedes-Benz GLS | 2026 BMW X7 |
|---|---|---|---|
| Maximum braked towing | 8,000 lbs | 7,700 lbs | 7,500 lbs |
| Construction | Body-on-frame (GA-F platform) | Unibody | Unibody |
| Low-range gearing | Standard (H4 / L4) | Not offered | Not offered |
| Center differential | Torsen limited-slip locking, 50:50 split | 4MATIC | xDrive |
| Terrain modes | Multi-Terrain Select — four low-range, five high-range | Not offered | Not offered |
| Descent control | Downhill Assist Control, standard | Not offered | Hill descent control |
| Suspension | Active Height Control with Adaptive Variable Suspension | AIRMATIC adaptive damping | Adaptive air suspension |
| Trailer stability aids | Trailer Stability Program | Trailer Stability Assist and Crosswind Assist | Integrated trailer stability control |
| Hitch provision | Towing preparation package | Class III on 450 and 580; Class IV on AMG GLS 63 | Factory-installed hitch required for maximum rating |
Towing and Payload. Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.
This is the LX’s strongest category, though the margin is narrower than usually presented: 300 pounds over the GLS, 500 over the X7. The real separation is structural. The LX is the only one here with a ladder frame, low-range gearing, a locking center differential and Crawl Control. For a household that tows on unpaved access roads or drives the fire-road trailheads in the Santa Monica Mountains above Encino, that hardware has no equivalent. For one towing a boat to a paved ramp twice a year, all three are more than adequate.
Mercedes-Benz GLS vs. BMW X7 vs. Lexus LX: Passenger Space and Cargo
Cargo volume gets measured at different points by different publishers, so every figure below is stated at the same point for all three vehicles.
| Specification | 2026 Lexus LX | 2026 Mercedes-Benz GLS | 2026 BMW X7 |
|---|---|---|---|
| Seating | 7 (LX 600, three-row) | 7 | 7 (six-seat configuration available) |
| Cargo behind third row | 11.0 cu ft | 17.4 cu ft | 12.8 cu ft |
| Maximum cargo | 64.0 cu ft | 84.7 cu ft | 90.4 cu ft |
| Front legroom | 41.1 in | 40.3 in | 39.8 in |
| Second-row legroom | 36.6 in | 41.9 in | 37.6 in |
| Third-row legroom | 31.1 in | 34.6 in | 33.3 in |
| Second-row configuration | 60:40 split-folding | Power-adjust with recline | Bench standard, captain’s chairs optional |
| Third-row configuration | 50:50 power-folding | 50:50 power-folding | Power-folding |
The Lexus LX loses this category clearly. It carries less behind the third row than either rival, trails the BMW X7 by more than 26 cubic feet at maximum, and has the least second- and third-row legroom. Shoppers whose first priority is space for seven should look hard at the Mercedes-Benz GLS, which leads every rear measurement. The LX’s one win is front legroom.
BMW X7 vs. Lexus LX vs. Mercedes-Benz GLS: Screens, Audio and Connectivity
| Feature | 2026 Lexus LX | 2026 Mercedes-Benz GLS | 2026 BMW X7 |
|---|---|---|---|
| Main display | 12.3-in touchscreen | 12.3-in touchscreen | 14.9-in curved touchscreen |
| Secondary display | 7-in lower control screen | 12.3-in digital cluster | 12.3-in digital cluster |
| Interface | Lexus Interface | MBUX | BMW iDrive 8.5 |
| Apple CarPlay and Android Auto | Wireless, standard | Wireless, standard | Wireless, standard |
| Premium audio | 10-speaker standard; 25-speaker Mark Levinson, 2,400 watts available | Burmester surround sound, standard | Standard audio; Bowers & Wilkins available |
| Head-Up Display | Standard on all trims | Available | Available |
| Navigation | Cloud Navigation with Google points-of-interest data | Augmented-reality navigation | Cloud navigation with video augmented-reality overlay |
| Wireless device charging | Standard | Standard | Standard |
| Over-the-air updates | Available with connected services | Standard | Standard |
All three arrive with wireless smartphone mirroring and a two-screen cockpit. The BMW X7 has the largest single display by a wide margin. The Lexus LX is the only one with a standard head-up display on every trim, and its 7-inch lower screen surfaces off-road functions — differential lock status, terrain mode, ride height — the other two have no need to display.
Lexus LX vs. GLS vs. X7: Standard Driver Assistance
| System | 2026 Lexus LX | 2026 Mercedes-Benz GLS | 2026 BMW X7 |
|---|---|---|---|
| Suite name | Lexus Safety System+ 3.0 | Standard Mercedes-Benz driver assistance | Active Driving Assistant |
| Forward collision | Pre-Collision System with Pedestrian Detection | Collision warning system, standard | Frontal Collision Warning with City Collision Mitigation |
| Lane support | Lane Departure Alert with Steering Assist; Lane Tracing Assist | Lane departure warning, standard | Lane Departure Warning |
| Blind spot | Blind Spot Monitor with Rear Cross Traffic Alert | Blind-spot alert, standard | Active Blind Spot Detection |
| Adaptive cruise | All-Speed Dynamic Radar Cruise Control with Curve Speed Management | Active Distance Assist DISTRONIC, standard | Adaptive cruise control |
| Driver attention monitoring | Included in Lexus Safety System+ 3.0 | Driver Attention Assist, standard | Included in Active Driving Assistant |
| Sign recognition | Road Sign Assist, standard | Not listed as standard | Not listed as standard |
| Parking assistance | Panoramic View Monitor with front and rear sensors | Surround-view camera, standard | Parking Assistant Professional, standard |
| Hands-free highway driving | Traffic Jam Assist, subscription | Not offered on this model | Highway Assistant, optional package, up to 85 mph |
The Lexus LX ships the deepest standard suite, including road sign recognition and emergency steering assist that neither rival lists as standard. The BMW X7 counters with the most capable optional system: Highway Assistant allows hands-free driving up to 85 mph on qualifying highways, which neither rival offers at any price.
Mercedes-Benz GLS vs. BMW X7 vs. Lexus LX: Warranty Coverage
| Coverage | 2026 Lexus LX | 2026 Mercedes-Benz GLS | 2026 BMW X7 |

Warranty coverage depends on the specific terms of your vehicle’s warranty agreement. Consult your owner’s manual or a qualified legal professional for guidance on your individual situation.
Three brands, three different answers. Lexus alone extends powertrain coverage two years and 20,000 miles beyond the bumper-to-bumper term. BMW alone covers rust perforation for 12 years and includes three years of scheduled maintenance. Mercedes-Benz folds powertrain into a single four-year comprehensive warranty with no separate extension.
On forecast resale value, the Lexus LX received a 2026 U.S. ALG Residual Value Award from J.D. Power at the model level, one of three Lexus models recognized that year. The brand-level premium award for 2026 went to a different manufacturer, so this is a segment result rather than a brand-wide claim.
BMW X7 vs. Lexus LX vs. Mercedes-Benz GLS: Fuel Economy
| Specification | 2026 Lexus LX | 2026 Mercedes-Benz GLS | 2026 BMW X7 |
|---|---|---|---|
| Entry model, city / hwy / combined | EPA-Estimated 17 / 22 / 19 | EPA-Estimated 19 / 24 / 21 | EPA-Estimated 21 / 25 / 23 |
| Mid model, city / hwy / combined | EPA-Estimated 17 / 22 / 19 | EPA-Estimated 14 / 20 / 16 | EPA-Estimated 16 / 21 / 18 |
| Top model, city / hwy / combined | EPA-Estimated 17 / 22 / 19 | EPA-Estimated 15 / 20 / 17 | EPA-Estimated 15 / 21 / 17 |
| Fuel grade | Premium required | Premium recommended | Premium recommended |
| Fuel tank capacity | 21.1 gal | 23.8 gal | 21.9 gal |
Fuel Economy. EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.
The LX’s single powertrain means consistent numbers across the range, which works against it at the bottom and for it at the top. Against the entry models most shoppers cross-shop, the LX is the least efficient. Against the V8 flagships, it is the most efficient by a comfortable margin. Confirm any rating at the EPA’s fueleconomy.gov.
Which Full-Size Luxury SUV Fits You
Choose the 2026 Lexus LX
Choose the LX if capability is a real requirement rather than a talking point: ladder frame, low-range gearing, locking center differential, an 8,000-pound tow rating and the longest powertrain warranty here. Accept that it is the slowest, least efficient at entry, and tightest for cargo and rear legroom.
Choose the 2026 Mercedes-Benz GLS
Choose the GLS if people and luggage come first. It leads every rear legroom measurement, leads cargo behind the third row, and offers the widest choice of engines.
Choose the 2026 BMW X7
Choose the X7 if you want the lowest price of entry, the best fuel economy, the largest screen, the most cargo with seats folded, and available hands-free highway driving.
Frequently Asked Questions
Is the 2026 Lexus LX worth its price premium over the GLS and X7?
It depends on what you are buying. The LX starts at $108,050 MSRP against $91,600 MSRP for the GLS 450 and $89,050 MSRP for the X7 xDrive40i. That premium buys body-on-frame construction, low-range four-wheel drive, a 500-pound towing advantage over the X7, and a powertrain warranty two years longer than either German rival. It does not buy more speed, more cargo room or better fuel economy, because the LX trails on all three.
Which of the three is most fuel efficient?
The BMW X7 xDrive40i, at an EPA-Estimated 23 MPG combined. The Mercedes-Benz GLS 450 follows at 21 MPG combined, and the Lexus LX 600 returns 19 MPG combined across all three of its gas trims. At the top of each range the picture reverses, where the LX’s 19 MPG combined beats both V8 flagships.
How much can each of these SUVs tow?
The Lexus LX leads at 8,000 pounds. The Mercedes-Benz GLS is rated at 7,700 pounds across all three gas models. The BMW X7 is rated at 7,500 pounds on every trim when equipped with the factory-installed trailer hitch.
Which has the most cargo space?
The BMW X7, at 90.4 cubic feet maximum. The Mercedes-Benz GLS follows at 84.7 cubic feet and leads behind the third row at 17.4 cubic feet. The Lexus LX is last in both, at 64.0 cubic feet maximum and 11.0 cubic feet behind the third row.
Which has the most third-row legroom?
The Mercedes-Benz GLS, at 34.6 inches. The BMW X7 follows at 33.3 inches and the Lexus LX has 31.1 inches. All three seat seven.
