LX 700h or GX 550? How Lexus's Two Body-on-Frame SUVs Compare on Towing, Off-Road Hardware, and 3-Row Specs

The 2026 Lexus GX 550 and LX 700h are both three-row, body-on-frame Lexus SUVs with genuine off-road hardware, towing ratings above 9,000 lbs (4,082 kg), and a full suite of luxury amenities. But they sit at meaningfully different price points and serve different buyers. The GX 550 is the starting point for buyers who want a capable, full-size off-roader in the Lexus family. The LX 700h is the flagship — a hybrid-electric vehicle with 457 system horsepower that costs significantly more and delivers a notably different level of cabin refinement, particularly in the Luxury and Executive VIP grades.

If you are choosing between these two, the question is usually one of scale. Both can tow. Both can go off-road. Both seat up to seven passengers. What changes are the powertrain, the technology ceiling, and how aggressively the top grades pursue cabin excellence versus trail capability.

At a Glance: GX 550 vs LX 700h

Note: The LX 700h actually tows less than the GX 550 despite its higher power output — 7,992 lbs (3,625 kg) versus 9,063 lbs (4,110 kg). For buyers where maximum towing matters most, the GX 550 holds an advantage.

Performance and Powertrain

Both vehicles use the same 3.4 L twin-turbo V6, but in entirely different configurations. The GX 550 runs on gasoline only, producing 349 hp and 479 lb-ft of torque. The LX 700h adds Lexus hybrid-electric technology — pairing the same V6 with hybrid components to generate 457 combined system horsepower and 583 lb-ft of system torque. The LX 700h's hybrid system also enables motor-driven power in the low range, which provides more precise throttle control on demanding terrain such as loose rock, steep descents, and deep snow. In these scenarios, the hybrid low-range advantage is tangible.

The GX 550 is the stronger towing vehicle. For buyers regularly pulling a boat, trailer, or camper at the top end of either rating, the 9,063-lb (4,110 kg) GX 550 tow rating provides more margin.

Off-Road Hardware

Both model families include Crawl Control, Multi-Terrain Select, Downhill Assist Control (DAC), and a locking rear differential. In Overtrail configurations, the GX 550 adds 33-inch all-terrain tires, a front skid plate, a transmission skid plate, front tow hooks, an onboard air compressor, and a multi-terrain monitor with underfloor view — making the Overtrail+ the more purpose-built trail vehicle of the two.

The LX 700h Overtrail+ (2 Row) brings its own off-road package: front and rear locking differentials (the GX 550 has only a rear lock on Overtrail grades), 33-inch all-terrain tires on 18-inch wheels, and a front skid plate. For buyers who want both locking differentials and the hybrid powertrain in a single package, the LX 700h Overtrail+ is the more capable option.

Cargo and Interior Space

The GX 550 offers a three-row interior with the rear two rows folding flat to create a large, flat cargo floor. The LX 700h provides a similar three-row layout, and at the Luxury and Executive VIP grades it steps into a noticeably more premium seating and upholstery package — including semi-Aniline leather and, on the Executive VIP, a power ottoman rear seat for the right-rear passenger.

Technology and Cabin

Both vehicles come with the 14-inch Lexus Interface touchscreen and Mark Levinson audio on upper grades. The LX 700h Luxury adds a dual rear-seat entertainment system with wireless Bluetooth headphones, a 4-zone automatic climate control system on the Executive VIP, and a rear seven-inch climate control screen. These features push the LX toward a more chauffeur-oriented experience that the GX lineup does not replicate.

Which SUV Fits Your Priorities?

The GX 550 is the right choice for buyers who prioritize maximum towing capacity, want six grades of configuration options (including two distinct trail setups), and see the Lexus flagship as a capable outdoor vehicle first. Its 9,063-lb (4,110 kg) tow rating leads the comparison by a meaningful margin.

The LX 700h is the right choice for buyers who want the hybrid powertrain's power output, fuel efficiency advantage at 12.7 L/100 km combined (versus 13.5 L/100 km for the GX), and the cabin refinement of a flagship SUV — particularly the Luxury and Executive VIP grades. The LX 700h Overtrail+ also offers front and rear locking differentials that the GX Overtrail does not match.
