The 2025 Lexus GX arrives looking like it was designed with a set square, a climbing rope, and a mild contempt for soft-roaders. Good. After years of selling the old GX 460 as a leather-lined relic with a thirsty V8 and a side-hinged tailgate from another geological era, Lexus has finally dragged its SUV classic into the present. The result is the GX 550: still body-on-frame, still properly four-wheel drive, still built for people who think “trail-rated” should mean more than surviving a gravel winery driveway. But now it has a twin-turbo V6, real torque, sharper tech, and styling that no longer apologizes for itself.
A Proper Reset, Not a Polite Refresh
Let’s get the obvious out of the way: this is not the old GX with a new grille and a larger screen. The 2025 Lexus GX rides on Toyota’s TNGA-F body-on-frame platform, the same heavy-duty architecture underpinning the Toyota Land Cruiser, Lexus LX, Toyota Tundra, and Sequoia. That matters because the GX has not been reimagined as a soft crossover in a cashmere sweater. It remains a real SUV, with full-time four-wheel drive, a two-speed transfer case, a locking center differential, and serious towing hardware.
The previous GX 460 used a 4.6-liter naturally aspirated V8 making 301 horsepower and 329 lb-ft of torque, routed through a six-speed automatic. Charming? Yes. Efficient? Absolutely not. Quick? Only if your other car was a mule. The 2025 GX 550 replaces it with a 3.4-liter twin-turbocharged V6 producing 349 horsepower and 479 lb-ft of torque, paired with a 10-speed automatic transmission.
That torque figure is the headline. It is 150 lb-ft stronger than the old V8, and you feel it everywhere: pulling away from a stop, climbing grades, and especially when the GX is asked to lug its big square shoulders through rough terrain. Lexus says properly equipped versions can tow up to 9,096 pounds, a massive jump over the old GX 460’s 6,500-pound rating and enough to make plenty of “lifestyle” SUVs look like decorative driveway furniture.
- Engine: 3.4-liter twin-turbo V6
- Output: 349 hp and 479 lb-ft
- Transmission: 10-speed automatic
- Drivetrain: Full-time 4WD with low range
- Maximum towing: Up to 9,096 pounds, depending on trim
- EPA fuel economy: 15 mpg city, 21 mpg highway, 17 mpg combined
- Seating: Five seats on Overtrail models; six or seven on other trims
Those fuel-economy numbers are not exactly Prius-adjacent, but let’s not pretend a brick-shaped, body-on-frame luxury SUV with full-time 4WD was ever going to sip fuel like a spa guest with cucumber water. The old GX 460 was rated at 15/19/16 mpg, so the new one is only slightly better on paper. The gain is not efficiency; the gain is performance. And on that front, the GX finally feels like it has been eating protein.
On Road: Quieter, Stronger, Still a Truck
The first thing you notice from behind the wheel is the driving position. You sit high, the hood is broad and visible, and the front corners feel easier to place than you’d expect from something nearly 197 inches long and more than 83 inches wide. This is not the slippery, low-cowl world of the Genesis GV80 or BMW X5. The GX feels upright, square, and deliberate. Lexus has leaned into the SUV-ness of it, and the result is far more honest than trying to disguise 5,500-ish pounds of truck as a sports sedan.
The twin-turbo V6 is smooth, muscular, and refreshingly unstressed. Peak torque arrives low and gives the GX the sort of shove the old V8 simply could not deliver without making a theatrical meal of it. The 10-speed automatic is generally well behaved, though it can occasionally shuffle ratios when you ask for a quick burst of acceleration after a long cruise. That is the tax you pay for having more gears than a Tour de France support van. Still, the powertrain is a huge improvement over the old GX. It feels modern, relaxed, and appropriately premium.
Independent testing of the GX 550 has put 0-60 mph performance in the mid-six-second range, which is perfectly respectable for a body-on-frame luxury SUV. More importantly, it feels quick where buyers actually use it: merging, passing, towing, and clawing up steep roads without wheezing. The old GX 460 had charm. The new GX has authority.
Ride quality depends heavily on trim. The Luxury and Luxury+ models are the boulevard choices, particularly with their larger wheels and more comfort-focused mission. They cruise well, isolate road noise effectively, and keep the cabin calm at highway speeds. But you never forget the GX has a ladder frame underneath. There is a little head toss over broken pavement, a bit of body movement in quick transitions, and enough mass in the steering to remind you this is not a unibody crossover with a Lexus badge and good manners training.
That is not a criticism so much as a warning label. If you want a creamy, road-biased family hauler, the Lexus TX will make more sense. If you want something that can tow a horse trailer Monday, crawl over rocks Saturday, and still look expensive outside a steakhouse, the GX is the one with dirt under its manicured nails.
Overtrail Is the One You Want
Lexus offers the 2025 GX in Premium, Premium+, Luxury, Luxury+, Overtrail, and Overtrail+ trims. The smart money, the fun money, and the money with a pulse should all look hard at the GX 550 Overtrail. This is the trim that gives the new GX its personality rather than just its price tag.
Overtrail models ditch the third row and seat five, which is a blessing if you care about cargo space, gear, dogs, recovery boards, or anything more useful than two punishment chairs in the back. They also bring the serious off-road kit: 18-inch wheels with 33-inch all-terrain tires, an electronically locking rear differential, underbody protection, Multi-Terrain Select, Crawl Control, and Lexus’s E-KDSS suspension system.
E-KDSS, or Electronic Kinetic Dynamic Suspension System, is one of those acronyms that sounds like it escaped from a corporate PowerPoint and yet actually does something valuable. It can vary the behavior of the stabilizer bars to improve wheel articulation off-road while preserving better body control on pavement. Translation: the GX can flex when it needs grip and tighten up when it needs composure. It is not magic, but on rutted trails it feels close enough.
Off-road, the GX is deeply convincing. Low range engages cleanly, visibility over the squared-off hood is excellent, and the throttle calibration is measured enough that you are not pogoing over obstacles like a caffeinated rental Jeep. The rear locker gives the Overtrail real bite, and the 33-inch tires do more for confidence than any number of “adventure-inspired” badges. A Land Rover Defender 110 still has a broader spread of off-road tech and a more sophisticated air-suspension party trick, but the Lexus counters with Toyota-grade durability credentials and a cabin that does not feel like it is trying quite so hard to impress your Instagram followers.
The Toyota Land Cruiser is the obvious in-house rival. It is cheaper, also built on TNGA-F, and uses a 2.4-liter turbo hybrid four-cylinder making 326 horsepower and 465 lb-ft. The Land Cruiser is excellent, but it is two-row only in the U.S. and less plush inside. The GX 550 Overtrail feels like the Land Cruiser’s richer, stronger, more leather-lined cousin who still knows how to use a Hi-Lift jack.
Best trim: GX 550 Overtrail. It is the version that makes the GX feel like a product with a point, not just a luxury SUV with a square jaw.
Cabin and Tech: Finally Living in This Decade
The old GX interior was built well but dated badly. It had the vibe of a private club that recently discovered Wi-Fi. The 2025 model fixes that with a cleaner dashboard, a 14-inch touchscreen, a 12.3-inch digital instrument cluster, wireless Apple CarPlay and Android Auto, and enough physical controls to prove Lexus has not completely lost its mind.
That last bit matters. Climate controls are still easy to use. Drive modes are accessible. The off-road controls are not buried under twelve layers of touchscreen nonsense. This is how it should be. Automakers keep trying to convince us that haptic sliders and screen-only climate menus are progress. They are not. They are cost-cutting in a tuxedo. Lexus, thankfully, has retained enough knobs and buttons to make the GX usable while bouncing along a trail or wearing gloves in winter.
Material quality is strong, though not quite at Lexus LS levels of pampering. The design is more rugged-luxury than old-school opulence, and that suits the GX. Overtrail models get excellent seats, durable trim, and a cabin that feels expensive without being precious. Luxury trims push harder into traditional Lexus comfort, with available second-row captain’s chairs, upgraded upholstery, and more convenience features.
The packaging is better than before, but not flawless. The third row in non-Overtrail models is useful for children or short trips, not full-grown adults with knees and opinions. Cargo room behind the third row is limited, as it is in most SUVs of this size that try to do everything at once. Fold the rear seats, however, and the GX becomes properly useful. Overtrail models, by skipping the third row, feel more honest and more practical for the kind of buyer who actually wants to carry outdoor gear rather than imaginary extra passengers.
Safety and driver-assistance tech are also up to modern expectations. Lexus Safety System+ 3.0 includes features such as adaptive cruise control, lane tracing assist, pre-collision warning with pedestrian detection, road sign assist, and proactive driving assist. The tuning is generally smooth, though lane assistance can be a little eager on imperfect roads. Still, compared with the old GX, this is like swapping a flip phone for a current smartphone.
Price, Rivals, and the Real-World Case
The 2025 GX starts in the mid-$60,000 range before options and climbs into the low-$80,000s for loaded Luxury+ and Overtrail+ models. That places it in a fascinating, slightly dangerous neighborhood. A well-equipped Acura MDX Type S is cheaper and better on-road. A Genesis GV80 is prettier inside and more refined. A BMW X5 drives circles around it on pavement. A Land Rover Defender 110 has more brand theater and broader off-road configurability. And the Toyota Land Cruiser gives you much of the same underlying hardware for less money.
So why buy the Lexus?
Because none of those rivals combines this exact mix of attributes. The MDX, GV80, and X5 are fundamentally road-first machines. Lovely things, but not vehicles you buy because you plan to drag them over ledges. The Defender is brilliant when it works and charismatic always, but long-term ownership costs and reliability reputation remain part of the conversation whether Land Rover fans like it or not. The Land Cruiser is the rational choice, but the GX brings more power, more luxury, more towing capacity, and a stronger premium identity.
The GX is not the best luxury SUV for everyone. It is too thirsty for commuters who only want a badge. It is too truck-like for buyers expecting a silent electric glide. It is too expensive if all you need is three rows and a school-run perch. But for the buyer who wants a real SUV that can tow, travel, crawl, camp, and still make the valet pay attention, the GX has a rare clarity of purpose.
There are annoyances. The fuel economy is mediocre. The ride can get busy on rough city pavement. The third row is compromised. Some Luxury trims with big wheels feel less convincing than the Overtrail because they lean away from the GX’s core talent. And while the V6 is strong, some traditionalists will mourn the loss of the old naturally aspirated V8 soundtrack. Fair enough. I miss cheap gasoline and manual handbrakes too, but time keeps moving.
Verdict: The GX Finally Knows What It Wants to Be
The 2025 Lexus GX is the rare redesign that does not sand away the character people liked in the first place. It modernizes the formula without turning the GX into another anonymous luxury crossover. It is stronger, sharper, more capable, and vastly better inside than the old GX 460, while still feeling like a machine built for more than mall duty.
The Overtrail is the hero trim, and frankly the one that makes the strongest argument for the whole lineup. It embraces the GX’s truck bones instead of hiding them. The Luxury models will appeal to buyers who want the look and the Lexus badge, but the Overtrail is where the engineering and the attitude line up.
Is it perfect? No. A BMW X5 is better to drive on-road. A Genesis GV80 has a richer cabin for the money. A Toyota Land Cruiser is the value play. A Defender has more old-world swagger. But the GX 550 has the one thing the old model was starting to lose: relevance. It feels tough without being crude, premium without being delicate, and modern without being fake.
RevvedUpCars verdict: Buy the 2025 Lexus GX 550 Overtrail if you want a luxury SUV with actual backbone. Skip it if your idea of adventure is parking near a trailhead for a selfie. The GX is back, and this time it brought torque.
