What's the difference?
Lexus has finally brought a plug-in hybrid to the Australian market with the RX450h+, and we’ve been testing the second-from-the-top Sports Luxury grade to see how it stacks up.
Promising a blend of electric efficiency and the high-end comfort Lexus is known for, this large SUV steps into a competitive segment. But does it deliver on both fronts?
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 RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.
You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.
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 RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.
The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.
And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.
Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.
The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.
If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.
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 RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.
Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.
Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.
Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.
Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.
The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.
One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.
Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.
That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.
Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.
My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.
There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.
At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.
Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.
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.
There are four variants in the RX range, and we’re testing the 450h+ Sports Luxury AWD, which sits just below the flagship and packs in plenty of premium kit for its $123,500, before on-road costs, price tag.
That makes it slightly more affordable than its main PHEV rivals; the BMW X5 xDrive50e (from $125,885 MSRP) and the Volvo XC90 Ultra (from $124,466 MSRP).
The Volvo does offer seven seats to the Lexus’ five, which may matter for larger families, and both rivals also outdo the RX on electric-only driving range - 65km in the RX compared with 77km in the Volvo XC90 and a generous 101km in the BMW X5.
Still, the RX fights back with a seriously stacked features list. Highlights include a panoramic sunroof, 10-way powered front seats with heating and ventilation, electrically folding rear seats (also heated and ventilated in the outboard positions), and a heated, power-adjustable steering wheel. Sound is taken care of by a premium 21-speaker Mark Levinson surround system.
Technology has had a solid upgrade with the 14-inch touchscreen multimedia display, 12.3-inch digital instrument cluster, digital rearview mirror, colour head-up display, live traffic navigation, wireless Apple CarPlay and Android Auto, 4G connectivity, four USB-C ports, one USB-A port and a fast wireless charging pad.
There’s also access to the 'Lexus Connected Services' app, allowing you to remotely lock or unlock the vehicle, pre-set the cabin temperature via three-zone climate control, configure driver profiles and even use your phone as a digital key.
Practical features include keyless entry and start, rain-sensing wipers, dusk-sensing LED headlights, rear sun-blinds, intelligent seatbelt reminders for the first two rows, a child presence alert and a hands-free powered tailgate. However, due to the plug-in hybrid system there’s no spare tyre, just a tyre repair kit.
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.
Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.
Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.
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.
The plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.
The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.
Using our real-world economy figure you can expect a range in excess of 1100km between fills.
The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.
While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.
Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.
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.
The RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.
The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.
Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.
The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.
The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.
Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.
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 RX earned a maximum five-star ANCAP safety rating in 2022, scoring highly across all protection categories: 90 per cent for adult protection, 89 per cent for child protection, 89 per cent for vulnerable road users, and 93 per cent for safety assist systems.
Standard safety gear includes eight airbags (dual front, front side, curtains, front centre, and driver’s knee) plus a comprehensive suite of driver aids. Standout features include emergency call functionality, child detection alert, side exit assist, front and rear collision warnings, park assist and emergency steering assist.
Additional tech covers blind-spot monitoring, driver attention monitoring, tyre pressure monitoring, daytime running lights, LED cornering lights, rear cross-traffic alert, lane departure alert, lane keeping assist, traffic sign recognition, and intelligent seatbelt warnings for the front two rows.
Visibility and parking are enhanced by a 360-degree camera system and front/rear parking sensors, while adaptive cruise control adds comfort on longer drives.
The rear seats have two ISOFIX mounts plus three top tether anchors, accommodating child seats safely. Autonomous emergency braking is active from 5.0 to 80km/h for pedestrians, cyclists, and backover and up to 180 km/h for cars.
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.
The RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.
Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.
This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.
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.
