2025 Lexus GX Review: Retro-Luxe SUV With Serious Off-Road Backbone

Powertrain and Platform: Old-School Bones, New-School Muscle

Underneath the squared-off bodywork, the 2025 GX rides on Toyota’s TNGA-F body-on-frame platform, shared with heavy hitters like the Toyota Land Cruiser and Toyota Tundra. This architecture is engineered for high torsional rigidity, improved ride refinement, and the ability to integrate modern driver-assistance tech with traditional off-road hardware.

The standard engine in North America is a 3.4‑liter twin-turbocharged V6 (badged 3.5L in some marketing), producing around 349 hp and 479 lb‑ft of torque. It replaces the outgoing naturally aspirated V8, trading displacement for boost while sharply increasing torque at lower rpm. That’s a meaningful upgrade for towing, loaded highway cruising, and low-speed off-roading where immediate torque delivery matters.

Power is routed through a 10‑speed automatic transmission tuned to keep the engine in its torque band and reduce hunting on grades. Enthusiasts will notice closer ratios in the lower gears for more decisive acceleration and taller gears at the top for more relaxed highway revs and better fuel economy than the old V8. While Lexus has not positioned this as a performance SUV, the powertrain feels more responsive than the previous generation without sacrificing refinement.

Crucially, a full-time 4WD system with a Torsen center differential and low range is standard, preserving the GX’s identity as a serious off-roader. Unlike many “AWD” crossovers, this system is designed for sustained operation on mixed surfaces, with torque distribution capable of reacting quickly to changing grip. A locking center differential is available, and higher trims add an electronically controlled locking rear differential for maximum traction in technical terrain.

Off-Road Capability: Angles, Hardware, and Real-World Use

Where most luxury SUVs settle for an off-road drive mode and some plastic cladding, the 2025 GX delivers substantial mechanical credibility. Approach, breakover, and departure angles are markedly improved over its predecessor, helped by shorter overhangs and a higher hood line. Exact figures vary by trim and wheel/tire package, but Lexus has clearly benchmarked the GX against traditional adventure SUVs rather than soft-roaders.

Suspension is a double-wishbone setup up front with a multi-link rear, tuned for both controlled body motion on pavement and articulation off-road. Higher trims and off-road-focused variants offer adaptive dampers, a disconnecting front stabilizer bar (or its electronic equivalent), and revised off-road calibration that allows more suspension travel before stability systems intervene.

Key off-road highlights enthusiasts will care about:

• **Two-speed transfer case** with a dedicated low range for crawling, steep descents, and heavy towing starts.
• **Available locking rear differential** to maintain forward motion when diagonally opposite wheels lose traction.
• **Crawl Control and Downhill Assist Control** (depending on trim), low-speed off-road cruise systems that modulate throttle and brakes to keep a constant speed on loose or rocky surfaces.
• **Underbody protection**, including skid plates in strategic areas such as the transfer case and fuel tank, providing real-world resilience on rocky trails.
• **Multiple terrain modes**, allowing drivers to tailor throttle response, transmission behavior, and traction control for sand, mud, rocks, or loose dirt.

Tyre choice is another telling indicator: off-road-oriented trims are available with all-terrain tires from the factory, offering stronger sidewalls and better bite in loose surfaces, though at the cost of some cabin quietness. Lexus’ decision to offer this configuration signals that the GX is not just styled for the overlanding crowd—it’s engineered to support them.

Interior and Technology: From Command Center to Family Lounge

Step inside the 2025 GX and it’s clear Lexus wants to bridge rugged capability with upscale comfort. The cabin design is upright, with strong horizontal lines and grab handles that hint at off-road use, but the materials and detailing are firmly in luxury territory.

The centerpiece is a large, high-resolution central touchscreen (in the 14‑inch range on most trims) running the latest Lexus Interface software. It supports wireless Apple CarPlay and Android Auto, over-the-air updates for select vehicle systems, and cloud-based navigation with real-time traffic data. Physical knobs and switches are wisely retained for key functions like volume, climate, and drive mode selection—a respect for usability that enthusiast drivers appreciate when bouncing around on rough surfaces.

Key interior and tech features that stand out:

• **Digital instrument cluster** with configurable layouts that can prioritize off-road data (pitch/roll, 4WD status, differential locks) or road-trip info (navigation, adaptive cruise, audio).
• **Available head-up display**, projecting speed, navigation prompts, and key alerts onto the windshield to reduce eye movement.
• **Premium audio systems**, including an available Mark Levinson surround system, tuned to compensate for the GX’s more upright, boxy cabin acoustics.
• **Seating configurations** in 5‑ or 7‑passenger layouts, with available captain’s chairs in the second row and fold-flat third-row seats for flexible cargo use.
• **High-end materials** such as semi-aniline leather, open-pore wood, and soft-touch surfaces even on lower door panels, elevating the cabin beyond its Toyota platform-mates.

Storage and ergonomics feel purpose-driven: deep door bins, a sizable center console, multiple USB‑C ports across all rows, and a reasonably flat load floor with the third row folded. Lexus has also moved away from the old side-hinged rear door toward a more conventional liftgate configuration, improving practicality in tight parking spaces and on steep trails where the former design could be awkward.

On the safety front, the latest Lexus Safety System+ suite is standard, folding in adaptive cruise control, lane centering assistance, automatic emergency braking with pedestrian and cyclist detection, and blind-spot monitoring. Importantly for a taller SUV, rear cross-traffic alert and a high-resolution surround-view camera system with underbody “see-through” views (by stitching multiple camera feeds) help mitigate blind spots off-road and in urban environments.

On-Road Dynamics: Daily Drivability Meets Long-Haul Comfort

While the GX is unapologetically truck-based, the new platform and twin-turbo powertrain dramatically improve its on-road behavior. The stiffer frame allows engineers to soften certain suspension settings for comfort without sacrificing control, resulting in better isolation of impacts and less body shudder over broken surfaces compared with the prior generation.

Steering is electrically assisted, with a moderate effort build-up and improved on-center stability, making highway travel less tiring. The turning circle remains larger than unibody crossovers, but for a body-on-frame SUV with off-road hardware, maneuverability is respectable. Lane-keeping assist systems gently nudge rather than aggressively tug at the wheel, which enthusiasts will appreciate for not feeling overbearing.

Noise, vibration, and harshness (NVH) are notably reduced. Acoustic glass, extra sound deadening in the firewall and floorpan, and active noise control tech all contribute to a cabin that remains hushed at cruising speeds—even on the more aggressive off-road tire options. The twin-turbo V6 is quieter and smoother than the old V8 at normal throttle openings, only making its presence known under hard acceleration.

Braking performance benefits from larger rotors and recalibrated ABS and stability control. Pedal feel is more linear, and fade resistance is improved, particularly significant for buyers who plan to tow close to the GX’s roughly 8,000‑lb towing capacity (exact rating may vary by market and configuration). Trailer sway control is integrated into the stability system, and a factory towing package includes wiring, hitch hardware, and cooling upgrades where required.

Fuel economy, while still not on par with smaller crossovers or dedicated hybrids, is meaningfully improved over the outgoing GX. The combination of downsized twin-turbo power, 10‑speed transmission, and more efficient drivetrain systems helps the new model deliver competitive efficiency for its class. For buyers moving from full-size truck-based SUVs or older V8 platforms, the reduction in fuel use will be noticeable over longer ownership periods.

Value, Trims, and Who the GX Really Suits

The 2025 Lexus GX is positioned as a premium adventure SUV—more refined than mainstream off-roaders, but less overtly performance- or fashion-focused than some European luxury rivals. Pricing reflects that middle ground: higher than comparable Toyota models sharing the TNGA-F platform, but generally more attainable than similarly capable German and British alternatives.

Trim structure varies by market, but broadly splits into:

• **Luxury-oriented trims**, emphasizing leather, wood, advanced driver aids, and comfort features like ventilated seats, panoramic sunroof, and high-end audio.
• **Off-road-oriented trims**, often wearing “Overtrail” or similar branding, prioritizing hardware like locking differentials, all-terrain tires, skid plates, unique dampers, and more aggressive approach/departure-friendly bumpers, while still offering a high level of comfort tech.

Ownership value is a key part of the GX proposition. Historically, Lexus body-on-frame SUVs have enjoyed strong reliability ratings, robust resale values, and lower long-term maintenance costs than many European competitors. Based on the shared platform with Toyota’s global off-road lineup and Lexus’ track record, the 2025 GX is likely to appeal strongly to buyers planning to keep their vehicle 8–10 years or more.

Who this SUV suits best:

• **Adventure-focused families** who actually use 4WD, tow campers or boats, and drive on unpaved or wintery roads regularly—but still want a quiet, comfortable interior.
• **Overlanding enthusiasts** who want a factory warranty and Lexus-level refinement instead of building up a base truck from scratch with aftermarket parts.
• **Buyers cross-shopping Land Cruiser, 4Runner, Defender, or G‑Class**, but seeking a blend of Japanese reliability, real off-road capability, and premium comfort.
• **Urban and suburban drivers** who value a commanding driving position, robust hardware for bad weather, and a long-term, low-drama ownership experience.

For shoppers primarily interested in fuel efficiency or a low seating position and sporting dynamics, Lexus’ unibody crossovers or hybrid options may be better fits. But for those who still believe a luxury SUV should be able to tackle more than a gravel driveway, the 2025 GX stands out as a rare combination of authenticity and refinement.

Conclusion

The 2025 Lexus GX marks a significant evolution of a long-running nameplate without abandoning the traits that earned it a loyal following. The move to a modern twin-turbo V6, TNGA-F platform, and advanced driver-assistance tech brings the GX firmly into the current decade, while the retention of full-time 4WD with low range, robust off-road hardware, and a ladder frame sets it apart from crossover-heavy rivals.

For enthusiasts and serious SUV buyers, the GX is not just another luxury box on wheels—it’s a thoughtfully engineered, genuinely capable machine that can comfortably commute during the week and confidently explore remote trails on the weekend. If your SUV shortlist includes models that must do more than just look the part, the 2025 Lexus GX deserves a close, hands-on evaluation.
