The all-new 2025 Lexus GX 550 lands in a sweet spot many SUV shoppers thought no longer existed: a genuinely rugged, body-on-frame truck that’s also quiet, tech-laden, and comfortable enough for daily driving. For years, the GX was an aging niche player; the 2025 redesign turns it into a spotlight model. This review looks past the marketing and dives into how the GX 550 actually performs, rides, and lives with—especially for buyers who want real off‑road capability without sacrificing refinement.
Platform and Powertrain: Traditional Bones, Modern Heart
Underneath the sharp, squared-off styling, the 2025 GX 550 sits on Toyota’s TNGA-F body-on-frame architecture, shared with the latest Toyota Land Cruiser, Toyota Sequoia, Tundra, and Lexus LX. This means a fully boxed ladder frame, beefy crossmembers, and high torsional rigidity—exactly what you want for towing and serious off-road work, and a departure from increasingly common unibody crossovers.
Power comes from a 3.4-liter twin-turbocharged V6 (Lexus designates it “3.4” though displacement is ~3.4L/3,445 cc) producing 349 hp and 479 lb-ft of torque, paired with a 10‑speed automatic. Compared with the outgoing GX 460’s naturally aspirated 4.6‑liter V8 (301 hp/329 lb-ft), the new engine delivers a significant torque bump at much lower rpm, making highway passing and towing feel noticeably stronger and more effortless. Full-time 4WD with a two-speed transfer case is standard across the lineup, and most trims include a Torsen center differential with a 40:60 default torque split that can vary based on traction needs.
Towing capacity now reaches up to 8,000 pounds when properly equipped, a competitive figure in the luxury midsize SUV segment and a meaningful upgrade over the prior generation. The 10‑speed transmission is tuned for smooth, unobtrusive shifts, though in some situations it can hunt between gears if you’re climbing grades at partial throttle. Crucially, Lexus retains a physical lever-style selector for the transfer case on certain trims, underlining that this is more than just a styling exercise in ruggedness.
Fuel economy, as expected, is not the GX’s calling card—but it is significantly improved. EPA estimates are in the mid‑teens city and low‑20s highway (exact figures can vary slightly by trim and wheel/tire choice). That’s a clear step up from the thirsty old V8, though buyers cross-shopping more efficiency-focused unibody SUVs or plug‑in hybrids will still see the GX as a compromise in this area.
On-Road Dynamics: Refined Truck, Not Disguised Crossover
On pavement, the GX 550 drives exactly like what it is: a well-sorted, modern body-on-frame SUV, not a disguised car-based crossover. Ride quality is notably more composed than the previous generation, thanks to the new platform’s greater stiffness, redesigned suspension geometry, and updated dampers. Road impacts are filtered and controlled, and body motions over large undulations are more settled, with fewer of the secondary bounces that plagued older truck-based SUVs.
Most trims use a double-wishbone front suspension and multi-link rear setup, with coil springs at all four corners. Adaptive dampers and Lexus’ Electronic Kinetic Dynamic Suspension System (E‑KDSS) are available on certain trims, actively decoupling or locking the stabilizer bars to balance roll control on-road with articulation off-road. In everyday use, the GX leans less in corners than you might expect, yet still allows enough compliance that potholes and expansion joints don’t transmit harshness into the cabin.
Steering is light but precise enough for confident lane placement, with typical Lexus isolation from kickback and rough surfaces. You won’t get the sharp, eager turn-in of a unibody performance SUV like a BMW X5 or Porsche Cayenne—this is a heavier, taller vehicle with a pronounced center of gravity—but the GX remains predictable and stable. Braking performance is strong and linear, with a firm pedal feel that inspires confidence, especially when towing or descending steep grades.
Noise, vibration, and harshness (NVH) control is excellent. The twin-turbo V6 is heard more as a muffled growl under load than an intrusive engine note, and wind noise is impressively low given the boxy profile. Larger off-road-oriented tire packages add some hum at highway speeds, but Lexus’ extensive sound-deadening measures keep the cabin remarkably calm. For buyers moving out of older BOF SUVs or large pickups, the 2025 GX will feel like a leap forward in on-road civility.
Off-Road Capability: Real Hardware, Not Just Modes
Where the GX 550 differentiates itself most clearly from many rivals is in its genuine off-road arsenal. Even base trims include full‑time 4WD with a low-range transfer case. As you move up the range—especially to Overtrail and Overtrail+ trims—the hardware becomes increasingly focused on trail work without turning the SUV into a hardcore, single-purpose rock crawler.
Overtrail variants add an upgraded off-road suspension tune, 33‑inch all‑terrain tires, underbody protection, and up to 8.9 inches of ground clearance, depending on spec. Lexus quotes approach, breakover, and departure angles that are competitive in the class (exact figures vary by trim and tire), and the TNGA‑F platform allows for robust mounting points for skid plates and recovery gear, a consideration many off-road enthusiasts appreciate.
The GX’s electronic aids are similarly serious. Multi-Terrain Select tailors throttle, traction control, and ABS behavior to conditions like mud, sand, or loose rock. Crawl Control acts as a low-speed off-road cruise control, managing throttle and brakes so the driver can focus on steering over technical obstacles. A Multi-Terrain Monitor uses cameras to provide near-360-degree views around and under the vehicle—particularly useful for cresting blind hills or placing wheels between rocks without a spotter.
The E‑KDSS system, where equipped, is particularly valuable off‑road. By hydraulically disconnecting the sway bars at low speeds, it allows significantly more wheel articulation, keeping tires on the ground for traction while avoiding the need for extreme lifts or aftermarket long‑travel kits. This blends capability with everyday usability; on-road, the system re‑engages to keep body roll in check.
For buyers who genuinely plan to use the GX for overlanding or frequent trail runs, the balance of factory capability and aftermarket potential is attractive. The ladder frame and conventional suspension layout make it friendly to modifications like upgraded shocks, lift kits, and armor, while the factory tech stack reduces the immediate need for complex add-ons just to reach remote campsites or trailheads.
Interior, Tech, and Practicality: From Overland Tool to Daily Luxury
Step inside the 2025 GX 550 and you’re greeted by a cabin that blends clean, horizontal design lines with traditional physical controls, resisting the trend toward all‑touchscreen interfaces. Materials are a clear upgrade from the previous generation: soft‑touch surfaces, available semi-aniline leather, real metal accents, and detailed stitching all contribute to a cabin that feels solid and upscale rather than flashy.
A 14‑inch touchscreen dominates the center stack, running Lexus’ latest infotainment system with crisp graphics, responsive touch inputs, and standard wireless Apple CarPlay and Android Auto. Redundant physical knobs and buttons for climate and volume remain—a practical decision that off‑roaders, in particular, will appreciate when driving with gloves or on rough terrain. The instrument cluster can be fully digital on higher trims, with configurable layouts and an available head-up display to reduce eye movement away from the road.
Seating is available in both two- and three-row configurations, allowing buyers to prioritize people or cargo. Front seats are supportive with a wide range of adjustments and available heating, ventilation, and even massage functions depending on trim. The second row can be configured as either a bench (for a total of seven passengers) or captain’s chairs (six passengers) with slide and recline functionality. The third row is improved compared with the previous GX but is still best suited for children or shorter trips for adults due to legroom and step-in height.
Cargo space benefits from a more practical rear design. Lexus has moved away from the unpopular side-hinged rear door of earlier generations toward a more conventional liftgate layout, often with an independent opening for the glass. This simplifies loading in tight parking spaces and makes it easier to access gear when hitch-mounted racks or trailers are in use. With the third row folded, the load floor is almost flat, and tie-down points are well positioned for securing bulky items or overlanding gear.
Tech and safety features are comprehensive. Lexus Safety System+ includes adaptive cruise control, lane-keeping assist, pre-collision braking with pedestrian detection, blind-spot monitoring, and rear cross-traffic alert. Multiple USB-C ports, a high-wattage charging outlet, ambient interior lighting, and optional premium audio systems (such as Mark Levinson) round out the everyday usability. The net effect: the GX is as comfortable handling a Monday commute or school run as it is serving as a long-distance adventure rig.
Ownership Case: Cost, Positioning, and Who the GX 550 Really Suits
The 2025 GX 550 sits in an interesting niche, overlapping both traditional luxury SUVs and more specialized off-roaders. Pricing starts in the mid‑$60,000 range and climbs higher with well-optioned trims and off-road-focused packages, firmly placing it in the premium segment. For that expenditure, buyers are getting a combination of features that’s increasingly rare: a true frame-based SUV with advanced off-road capability, high interior refinement, and strong towing credentials under a luxury badge.
Operating costs will reflect its size and configuration. Fuel economy is improved but still modest, and owners should budget accordingly for fuel, high-quality tires (especially all-terrains on Overtrail variants), and regular maintenance on a complex 4WD system. That said, Lexus’ reputation for long-term reliability and durability—reinforced by the related Land Cruiser and Lexus LX platforms—suggests that the GX will age more gracefully than many European competitors with more complex drivetrains and electronics.
Resale value is likely to be strong, especially for trims with desirable off-road equipment, given the growing interest in overlanding, remote travel, and “go-anywhere” family vehicles. Insurance costs will vary by region and driver profile but generally track with other midsize luxury SUVs. For buyers comparing lease deals, the GX’s expected residual strength may help keep monthly payments competitive relative to sticker price.
The GX 550 is best suited to buyers who truly need—or realistically will use—its capabilities. If your driving is almost entirely suburban and you never tow, never leave pavement, and prioritize maximum fuel economy and a car-like ride, a unibody luxury crossover may be a better fit. But if you want a vehicle that can comfortably accommodate family duty during the week and confidently tackle trails, mountain passes, or a boat launch on the weekend, the GX 550 makes a strong case.
Conclusion
The 2025 Lexus GX 550 successfully bridges a gap that many thought the industry was abandoning: it’s a legitimate, ladder-frame 4x4 tuned for modern expectations of safety, comfort, and tech. The twin-turbo V6 and TNGA‑F platform deliver a meaningful improvement in performance, refinement, and efficiency over the previous generation, while the off-road hardware and electronic aids give it real trail credibility straight out of the showroom. Inside, the mix of high-quality materials, robust infotainment, and thoughtful packaging makes it as livable as any contemporary luxury SUV.
For car enthusiasts and serious shoppers alike, the GX 550 stands out not because it chases every trend, but because it doubles down on being a capable, durable SUV that happens to be wrapped in Lexus-level polish. If your next vehicle needs to balance school runs, road trips, towing, and genuine off-pavement adventures, the 2025 GX 550 deserves a close, test-drive-level look.
