What's the difference?
The new Lexus GX 550 showcases a brand new design for its third-generation iteration but the model is new to the Australian market.
And while it hasn't been as hotly anticipated as its cousin, the Toyota Prado, it's still one that should excite. It's a capable full-time four-wheel drive that manages to look good on- and off-road! It feels like a breath of fresh air.
Will it find itself more likely adorning the garage of a city slicker? Perhaps, but you can't deny it has some star power now with its design and it couldn't have come soon enough. Especially when you compare the flagship Sports Luxury grade my family and I have on test to its European luxury rivals, the BMW X7 and Land Rover Defender.
Aussie buyers could be excused for being wary of SsangYong, given the marque’s chequered history involving numerous ownership changes, crippling debts and in 2021 its rescue from the jaws of receivership by Korean industrial conglomerate KG Group.
However, the KG Group’s corporate rehabilitation of the troubled carmaker was completed in 2022, allowing the renewed SsangYong Motor (renamed KG Mobility in Korea) to hopefully focus on its core business of producing 4x4 SUVs and pick-ups, with increasing use of electrification planned for future model development.
As part of this renewal, in late 2023 SsangYong Australia announced MY24 updates to refresh its local 4x4 Musso ute and Rexton seven-seater SUV ranges, which, combined with a Merv Hughes-hosted marketing campaign, is aimed at building brand appeal and sales through its 70-plus national dealer network.
We were recently handed the keys to the latest Rexton, which competes for buyers in Australia’s fiercely competitive ‘Large SUVs under $80K’ segment that hosts more than 20 rivals.
The new Lexus GX 550 Sports Luxury looks fantastic and has enough mod cons to satisfy a family but it’s not as luxurious as you’d expect from a premium brand and the fuel economy and driving range will turn off some. But if you’re still interested, there’s a lot here that will make you happy and it’s one of the smoothest 4WDs I’ve driven.
If KG Group can provide the long-term stability and new model investment that has eluded SsangYong for so long, the brand could have a promising future in Australia judging by the MY24 Rexton Adventure. It’s a solid package and what it lacks in benchmark ANCAP safety and third-row comfort is offset by a compelling driveaway price, generous warranty and national dealer network. So, if you’re looking for a feature-packed 4x4 seven-seater SUV for less than $55K, you might be pleasantly surprised by this competent Korean.
The new GX 550 looks massive and while it shares the same platform as the Toyota LandCruiser 300 series, it doesn't share all of its bulk. They both stand at 1980mm wide but differ on length (5015mm vs 4980mm) and height (1670mm vs 1950mm), respectively.
The new design is fabulously rugged but each body panel looks meticulously crafted and is just the right size. This just means the proportions look right and your eye sort of glides over the big body rather than stopping on any one feature.
But having said that, there are a lot of nice features to focus on, like the long LED headlights and rear strip light, auto-folding side steps, 22-inch alloy wheels and sharply styled rectangular side mirrors.
The tailgate window can also be opened if you need to pop something into the boot but don't want, or have the space, to open the tailgate itself.
The styling takes a minor nose dive once you hit the cabin, though, because it doesn't look as sumptuous as you'd expect in a premium SUV.
I love the utilitarian and military vibe of the vertical dashboard, chunky air vents and relatively small windscreen. It looks great but some trims are plasticky and the touchpoints, while soft, are not Lexus-plush.
However, the technology looks gorgeous with an integrated 14-inch multimedia display and a 12.3-inch digital instrument cluster. The fixed sunroof with its two settings (clear or opaque) is also a lovely feature.
But on a whole, the GX 550's European rivals outclass it with their flashier cabins.
With its 4850mm overall length and 1960mm width, the Rexton rides on a 2865mm wheelbase with a compact 11-metre turning circle.
Its smooth ride comes from four-coil suspension with double-wishbones up front and an independent multi-link arrangement in the rear. For those venturing into the rough stuff, it has 20.5 degrees approach and departure angles, 20 degrees ramp break-over angle and 203mm of ground clearance.
Looks are subjective, of course, but we reckon it has attractive and cohesive styling, with its prominent and ornate diamond-style grille complimented by distinctive side-body contours that can’t be mistaken for other SUVs.
The interior has a premium look and feel, with lots of exposed stitching along soft-touch seams and a tasteful blend of contrasting surfaces including chrome, satin chrome, piano black and textured patterns.
There’s good attention to detail and build quality is excellent, but there are some annoying design quirks like the need for the front passenger to access a touchscreen menu just to adjust the audio volume.
The second-row of seating has a/c vents in the centre console and is spacious even for tall people like me (186cm). When sitting behind the driver’s seat in my position, there’s about 60mm of clearance between my knees and the driver’s seat backrest, which combined with ample head and shoulder room makes for a comfortable ride.
By contrast, the third-row seating is strictly for young kids, as there are no adjustments for the second-row’s backrest angle or fore/aft base cushion positioning to accommodate taller frames like mine. The side windows in the thick rear roof pillar are also conspicuously small, which adds to a claustrophobic feel.
Fortunately, access to the third-row is made easier by the 60/40-split second-row, which can be folded and tumbled forward.
However, given I’ve found tolerable third-row comfort in some rival seven-seaters, the Rexton’s third-row is my only gripe for those with longer limbs.
The cabin of the new GX 550 is fairly practical with plenty of head- and legroom in each row (yep, even the third!). When you first hop in, it can feel a big snug on elbow-room but this feeling quickly dissipates.
Despite a 215mm ground clearance, access is pretty good for the front and middle rows due to the wide door apertures and side-steps. Third row access is a bit awkward for an adult but my eight-year old loved scampering back there this week.
The electric front seats are comfortable with their extra functions and I like the way the massage feature extends to the seat cushion as it limits fatigue on longer journeys. However, you sit on top of them rather sink into them which makes it feel a little trucky at times.
The wide middle row has a bench seat that will be comfortable for kids but an adult might get a sore behind on a long trip. The transmission tunnel also compromises foot room for adults but the seat is wide enough to make use of all three top-tether anchor points (there are ISOFIX mounts too).
It was a little bit of an effort to lift my big booster seat into the back because the GX 550 sits so tall but otherwise, there's plenty of room around a child seat for them not to feel like a sardine.
Individual storage is made up of a glove box that fits an owner's manual, a small shelf in the dashboard and a middle console that doubles as a cool box (mini fridge) and can fit up to four cans or bottles in it.
Each row gets four drinkholders and two USB-C ports but the front also enjoys a 12-volt socket and wireless charging pad. There's a 220V domestic plug port in the boot for larger appliances, too.
It's sometimes awkward to use the wireless charging pad because it's easy for your phone to slide around on it and it quite often disengaged from charging.
My son enjoyed all of the other amenities in the middle row, like the reading lights, climate control, two USB-C ports and retractable sunblinds and I applaud carmakers when they position rear directional air vents in the pillars and/or roof. It just makes it so much easier to cool down sweaty kids!
The 14-inch multimedia display has clear graphics and a responsive touchscreen. The layout is easy enough to get used to after spending some time with it and the sat nav is simple to use.
I like that the sat nav directions can be pulled into the 12.3-inch digital instrument cluster and head-up display.
There is a Lexus connected services app, which you get a three-year subscription to. It's easy to connect to the wireless Apple CarPlay and there is also wireless Android Auto.
The system also has Bluetooth and digital radio, which is a delight to use through the 21-speaker Mark Levinson sound system.
The cabin is rounded out by the well-shaped boot which has a massive 1063L of capacity when the third-row is folded. That's been more than enough for my family's needs this week and my German Shepherd was pretty comfy back there, too. The powered tailgate has a kick-function and there is a full-size spare wheel underneath the car.
With its 2130kg kerb weight and 2960kg GVM, our test vehicle has a sizeable load capacity of up to 830kg, which should be ample for five occupants and their luggage.
It’s also rated to tow up to the class-benchmark 3500kg of braked trailer and its 350kg maximum tow-ball download is compatible with that requirement.
Plus, its generous 6460kg GCM (or how much it can legally carry and tow at the same time) means it can legally tow its maximum trailer weight while carrying its maximum car-load, which is a practical set of numbers for just about any recreational requirement.
Front-row cabin storage includes cup/bottle-holders and a small bin in each front door, plus a single glove box. The stylish centre console has a bin up front with sliding-lid, two cupholders in the middle with another sliding-lid, plus a box at the rear with hinged padded-lid that doubles as a driver’s elbow rest.
Those seated in the second-row get a cup/bottle holder and bin in each door, plus pockets on each front seat backrest. The fold-down centre armrest has two more cupholders and a handy hidden compartment that’s ideal for small items. Third-row occupants get storage bins on each side but no cup/bottle holders.
Accessing the cargo area through the power tailgate reveals 236 litres (VDA) of load volume with the third-row seats upright. This expands to 641 litres with the third-row folded flat and 1806 litres (or more than 1.8 cubic metres) with the second and third-rows folded.
The cargo area’s rear floor has a two-tiered design, with the top floor lying flush with the third-row seats when folded but it can be removed to reveal a lower floor that provides a second level of storage. There’s also a usefully large bin in the right-hand-side wall cavity. The only things missing are sturdy load-anchorage points at floor level to secure cargo nets or straps.
The Lexus GX 550 shares the same platform as the recently introduced Toyota Prado but both models are now based on the same 'body-on-frame' platform shared by the beastie Toyota LandCruiser 300 Series. So it's bigger and features a more rigid chassis than before.
Surprisingly, that hasn't translated to a massive price tag for the GX 550 and you can pick up the flagship grade on test for this review for $128,200, MSRP.
Which sounds inexpensive when you compare it to the BMW X7 xDrive 40i M Sport which is priced from $171,300 MSRP but the Land Rover Defender 110 P400 X-Dynamic HSE is a lot closer at $128,815 MSRP.
The only issue here is that shared platform, because while they don't share the same powertrain, the flagship Toyota Prado Kakadu ($99,990 MSRP) is still almost $30K more affordable and boasts a similar equipment list. So, ask yourself, is it the brand and engine you're after or the new good looks?
The standard equipment is well-rounded with a 14-inch touchscreen media display with satellite navigation and wireless Apple CarPlay and Android Auto.
A fully digital 12.3-inch instrument cluster, colour head-up display, three-zone climate control and a 21-speaker Mark Levinson sound system round out multimedia requirements.
Other technology includes a digital rear view mirror, two USB-C ports in each row, a 12-volt socket, a 220-volt domestic outlet and a wireless charging pad.
There are two particularly handy features for families, the 'cool box' (basically a mini fridge) middle console and rear retractable sun-blinds.
The fixed panoramic sunroof features two settings allowing you to make it clear or opaque. The electric front seats feature heat, ventilation and massage functions and the rear outboard seats are heated as well. The third row electrically adjusts and there are multiple buttons throughout the car to access this feature.
Upgraded leather-accented upholstery is standard in the flagship grade and is available in three combinations. The Sports Luxury also features 22-inch alloy wheels, a full-size spare wheel and a powered tailgate with kick-function.
Our test vehicle is the new ‘Adventure’ model, which serves as the middle-grade offering between the entry-level ELX and top-shelf Ultimate.
It’s equipped with the same 2.2-litre four-cylinder turbo-diesel, eight-speed automatic and part-time 4WD as other Rextons, for a drive-away price of only $54,000 (our 'Space Black' metallic paint is a $595 option).
That pricing looks razor-sharp compared with mid-grade 4x4 seven-seaters offered by segment leaders like the Isuzu MU-X LS-U ($61,400), Ford Everest Trend ($66,790) and Toyota Prado GXL ($69,530).
And they are 'list' prices (not including on-road costs) whereas the Rexton is 'drive-away-no-more-to-pay'.
The MY24 upgrades include a new dash layout and high-mounted 12.3-inch multimedia touchscreen with Apple/Android wired connectivity. There’s also a restyled dual-zone climate control hub with touchscreen, plus new lower body mounts for improved ride quality.
The Adventure brings numerous luxuries like a walk-up welcome system (mirrors unfold and puddle lamps illuminate), touch-sensing front door locks with walk-away auto door-locking, power tailgate and soft-touch synthetic leather seats with the fronts offering power adjustment, heating and cooling.
The second-row outer rear seats and steering wheel are also heated, plus there’s speed-sensitive power steering and tyre pressure monitoring.
These appointments are in addition to the base ELX’s generous standard equipment list including 18-inch 'diamond-cut' alloy wheels with 255/60 tyres and a full-size alloy spare, LED dusk-sensing headlights/DRLs/front fog lights/tail-lights, heated door mirrors, a four-way-adjustable leather steering wheel and 12.3-inch driver's digital instrument display.
There are also four USB-C ports (two front and two in second row centre console), three 12-volt outlets (front console box, second row centre console and cargo area), electric parking brake, reversing camera, front and rear parking sensors and more. It's fair to say the Rexton Adventure is feature-packed.
All GX 550 grades share the same 3.5L V6 twin turbo-petrol engine which produces up to 260kW of power and 650Nm of torque.
This 4WD has high- and low-gearing, as well as a bunch of driving modes to suit most occasions, like 'Eco', 'Comfort', 'Sport' and 'Sport+'.
The 10-speed automatic transmission shifts through its gears smoothly and it always feels like it's engaged in the right gear. Which isn't always the case for a big SUV!
The Sports Luxury is fitted with a towing hitch and cover but unlike the base Sports grade which has a 3.5-tonne braked towing capacity, this model only has a 3130kg capacity which might not appeal to families with big toys to tow.
The quiet and refined 2.2-litre, four-cylinder, turbo-diesel, which meets Euro 6 emissions standards, produces 149kW at 3800rpm and 441Nm across a 1000rpm-wide torque band between 1600-2600rpm. It provides energetic response in city and suburban use.
This engine is paired with an equally refined eight-speed torque converter automatic, with overdrive on its sixth, seventh and eighth ratios ensuring low-rpm operation and optimum fuel economy at highway speeds.
Sequential manual-shifting is available using the steering wheel-mounted paddles and there's a choice of three drive modes ('Power'/'Winter'/'Eco') which can be selected using a console button.
The part-time, dual-range 4WD system is controlled by a console dial, offering the choice of 2H (2WD high-range), 4H (4WD high-range) and 4L (4WD low-range). It also has an auto-locking rear diff to optimise traction as required.
I didn’t have high hopes for fuel economy because the official combined (urban/extra-urban cycle figure is a hefty 12.3L/100km but after mostly open-road driving, with some urban stuff mixed in, my real-world average came in at 11.8L.100km! This figure is based on my actual km travelled (358km) and litres of fuel used (42.41L).
While I’m surprised by the fuel usage result, I wouldn’t say this car has good fuel economy compared to its diesel-powered counterparts but it’s not terrible!
The GX 550 has a relatively small fuel tank compared to its Toyota cousins at 80L and based on the combined fuel cycle, you’ll get a theoretical driving range of up to 650km.
Not all that great. Not for a big family mover and not if you’re typically driving in the city, where fuel usage will be a lot higher.
The GX 550 only accepts premium unleaded petrol (95 RON), too.
SsangYong claims an official combined cycle average of 8.7L/100km. At the completion of our 307km test, which comprised mostly city and suburban driving with a bit of highway travel, mostly in Eco mode with up to five occupants on some trips, our figure calculated from fuel bowser and trip meter readings came in at 11.0L/100km.
Although higher than SsangYong’s claim, it was within the usual 2.0-3.0L/100km discrepancy between official and ‘real-world’ figures. So, based on our numbers, you could expect a driving range of more than 600km from its 70-litre tank, which is not bad. Based on the official figure, driving range extends to around 800km.
Oh my goodness the Sports Luxury is a masterclass on 4WD refinement! You never feel the bulk or weight of this massive SUV when you’re driving it. The power delivery is effortless and there’s lots of grunt available when you hit hills.
The handling is also very good with responsive steering and enough road feedback as a driver to make you feel comfortable with what the car is doing. There is some roll in corners but it can tackle more corners at speed than I thought it would.
The high driving position makes me feel like I can see a long way ahead yet while visibility is mostly good, it can be compromised when you have the side window shades and the third row headrests up. Which is why I love the digital rear view mirror.
Overall, ride comfort is good with forgiving suspension and low cabin noise, even at higher speeds. It’s pretty easy to chat with all rows and there’s not a lot of engine noise which adds to the refinement. I do like hearing a V6 rumble but that’s just a personal preference.
I was a little worried about hitting my local Westfield car park but this is a nimble SUV to manoeuvre and parking it is a breeze with the 360-degree camera system and parking sensors.
The Rexton’s overall refinement and build quality are evident when you get behind the wheel. It offers good adjustability for driver comfort and the fundamentals of the vehicle are sound, as there were no red flags during our test.
The engine is smooth and quiet with good all-around performance, the automatic transmission shifts quickly and smoothly, the steering is nicely weighted and communicative, the brakes provide reassuring response and the ride quality is supple over bumps yet disciplined enough to provide good handling response.
It’s also pleasantly quiet at highway speeds, with low tyre and wind noise. Engine noise is also minimal, given that it requires only 1600rpm to maintain 110km/h, ensuring low-stress cruising.
Most of our driving time was spent in Eco mode, as we found performance in this setting more than adequate for our purposes. We did briefly use the Power mode but didn’t notice any significant change in response.
The new GX 550 hasn’t been tested by ANCAP and is unrated but its cousin, the Toyota Prado, which shares the same platform just achieved a maximum five-star rating from assessment in 2024. It's fair to expect a good result for this model.
Overall, the Sports Luxury has a long list of standard safety equipment and features nine airbags which is good for a family SUV.
Safety equipment includes adaptive cruise control, lane departure alert, lane keeping aid, traffic sign recognition, emergency steering assist, driver monitoring, safe exit assist, emergency call functionality, blind-spot monitoring, rear cross-traffic alert and tyre pressure monitoring.
The GX 550 has autonomous emergency braking (AEB) with pedestrian, cyclist, motorcyclist and junction turning assist.
No ANCAP rating (as yet). Even so, it comes with numerous passive and active safety features highlighted by dual front, side and curtain airbags plus a driver’s knee protection bag (but no centre airbag between driver/front passenger).
There’s also AEB, lane assistance, blind-spot warning and rear cross-traffic alert, trailer sway control, hill descent control, front/rear parking sensors, reversing camera and more, but a notable absentee is speed-sign recognition and the cruise control is non-adaptive. There are also ISOFIX child seat anchorages on the two outer second-row seating positions plus top tethers for all three.
Lexus offers the GX 550 with a five-year/unlimited km warranty, which is fairly standard compared to its Euro rivals.
You get five years capped-priced servicing which costs $5950 but the servicing schedule is a bit of a bear at every six months or 10,000km, whichever occurs first.
Warranty cover is seven years/unlimited km warranty plus seven years roadside assist.
Scheduled servicing is every 12 months/15,000km whichever occurs first.
The first seven scheduled services run to $375 each, up to seven years/105,000km, for a total of $2625.
