The 2025 Lexus LX 700h debuts in Northern California, marking a significant advancement in the luxury SUV segment. For the first time, the LX features a hybrid powertrain, combining performance, efficiency, and legendary off-road capability. The new LX Overtrail package further enhances its rugged appeal, incorporating triple-locked differentials—a feature not seen in the LX since the 1990s.

A Blend of Luxury and Off-Road Performance

Unlike the GX, the LX does not offer an Overtrail+ trim, as it remains focused on luxury. However, the Overtrail package does include 18-inch wheels with 33-inch Toyo Open Country A/T III tires, matte black exterior accents, and an updated electronic suspension system for improved off-road handling.

With the Toyota Land Cruiser and GX now based on the J250 Prado platform, the LX remains the only J300-based luxury SUV available in the U.S. The hybrid powertrain increases the LX’s appeal by offering enhanced horsepower and torque, while also providing a slight boost in fuel efficiency—an essential factor for prospective buyers in this segment.

Off-Road Enhancements: The Overtrail Experience

One standout feature of the LX 700h Overtrail is its suspension system. Unlike competitors using air suspension, Lexus implements a hydraulic-based adjustable suspension, prioritizing durability and performance on rough terrain.

Despite the additional weight from the hybrid system, the 3.5-liter twin-turbocharged V6 hybrid engine generates an impressive 457 horsepower and 538 lb-ft of torque—surpassing the Toyota Tundra and Sequoia, which have the same powertrain but are limited to 437 horsepower. Lexus attributes this increase to unique tuning and a higher octane fuel requirement, optimizing torque distribution throughout the rev range.

Reliable Hybrid Technology for Off-Roading

Lexus has reinforced the hybrid system for reliability, especially in off-road conditions. The battery pack is enclosed in a waterproof casing, protecting it from water crossings. Additionally, an extra alternator ensures that the 12-volt system can operate the electric motor’s clutch even if the hybrid system malfunctions.

During our test drive in Napa Valley, the hybrid system’s added 500-pound weight was noticeable on highways. The all-terrain tires generated some road noise, though the low-revving hybrid engine helped reduce intrusion. Lexus has clearly engineered the hybrid LX to uphold the reliability standards of past LX models.

Adaptive Performance for Any Terrain

Taking the LX Overtrail off-road revealed its advanced suspension articulation and intuitive electronic adjustments. The ride height automatically increases, offering extra ground clearance when necessary. In 4-Low mode, the LX lifts by up to four inches, with manual adjustments available through the center console controls.

The J300 platform provides more suspension articulation than the J250 GX, compensating for the absence of an electronic Kinetic Dynamic Suspension System (e-KDSS). The triple-locking differentials enhance traction, though they were rarely needed during testing due to the LX’s excellent grip and power distribution.

However, shifting between 4Lo and the rear locker proved somewhat inconsistent, requiring multiple attempts before engaging properly—an unexpected issue for a high-tech luxury SUV.

Hybrid Power Improves Driving Dynamics

On gravel and dirt roads, the instant torque from the hybrid system provided responsive acceleration, making paddle shifters largely unnecessary. The hybrid’s additional weight seemed to lower the center of gravity, improving stability on uneven surfaces.

The Overtrail-exclusive Earth-tone paint and Nori Green Pearl complement the SUV’s rugged design, especially when covered in a light layer of dust. Meanwhile, the luxurious interior remains a highlight, with ventilated and massaging seats ensuring comfort throughout long drives.

Interior Technology: A Balance of Luxury and Functionality

Inside, the dual-screen infotainment system operates smoothly, though the lower climate and vehicle controls screen could benefit from an update. While Lexus retains physical buttons for essential driving functions, the center console layout appears somewhat cluttered compared to other premium SUVs.

For those prioritizing passenger comfort, the Ultra Luxury trim stands out with captain’s chairs and an elevated second-row experience. However, selecting this package removes the third row, which is still available in other trims despite minor cargo space reductions due to the hybrid battery placement.

Fuel Economy and Cost Considerations

The hybrid system offers only a slight improvement in fuel efficiency, with city MPG increasing from 17 to 19 MPG, while highway ratings remain at 22 MPG. A notable drawback is the reduced 17.97-gallon fuel tank, down from 21.14 gallons in the non-hybrid LX 600—limiting driving range for those who venture far from refueling stations.

Starting at $115,350, the LX 700h Overtrail carries a hefty price tag compared to the GX 550 Overtrail, which is nearly half the cost. Additionally, non-hybrid Overtrail models are available in other markets but not in the U.S., a notable omission given the hybrid’s limited fuel efficiency gains.

Who Should Buy the 2025 Lexus LX 700h?

For those prioritizing on-road refinement and hybrid efficiency, the F Sport Handling package may be the better option. Featuring a Torsen torque-biasing rear differential instead of locking differentials, it also benefits from the hybrid’s quicker 0-60 mph time, shaving off half a second compared to the non-hybrid LX 600.

Ultimately, while the LX 700h Overtrail excels in luxury and capability, its higher price, added complexity, and reduced fuel tank capacity make it less suitable for serious overlanding. If Lexus had introduced a plug-in hybrid system, it might have provided a stronger value proposition. However, for those seeking a high-end, hybrid-powered, seven-seater SUV with a balance of off-road capability and luxury, the 2025 Lexus LX 700h remains a compelling choice.
