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?
When you look at a Lexus LX, you see a distinct resemblance to a Toyota LandCruiser. That’s understandable given that, fundamentally, the Lexus LX is a comprehensively gussied-up Toyota LandCruiser.
Built to put the luxury brand into the large SUV game, and taking advantage of Toyota's huge product portfolio, it's clear that this is not for chucking down the side of a mountain (although it can absolutely do that if asked, as long as you're on good terms with your local paint shop).
Lexus is - or more accurately, LX buyers are - very clear about how folks use the LX: it’s a city car. So it's got all the sophisticated city looks, with skirts and bling and big shiny alloy wheels. Whether there's a point to all that is irrelevant - there are clearly people, like you, who want a posh LandCruiser.
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.
The Lexus is awkwardly big and not very fleet of foot when you're negotiating the commute to work, school or the shops. It slurps fuel at a rate we're not used to seeing these days and it's not the easiest to park, even with all of its cameras and beepers.
The LX is far more at home out on the highway, where it is incredibly comfortable and quiet. One imagines the diesel entry-level model would do it all, but with less consumption. If you must have a V8, the LX 570 without the S might be even more comfortable without the sports dampers.
Either way, it's a lot of car for the suburbs.
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.
The LX came in for a facelift in 2021, perhaps to differentiate it from its Toyota sibling and, according to the press release, “ its level of urban sophistication.” That kind of tells you where this car is going to spend all of its time, doesn’t it?
There’s the new spindle grille that dominates the nose, with some clever detailing to make it look a bit more sporty and dramatic. Around the car there are modified bumpers, skirts, new wheel designs, all that kind of thing. It does look sportier, but there’s no way to hide the visual bulk of such a big unit.
The interior is largely unchanged and the ruggedness is softened somewhat by semi-anline leather trim and alloy sports pedals. It’s terribly conventional and very usable, but there’s none of the excitement or innovation you'll find in other, more recent Lexus cabins.
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.
Hellooo?! I think there’s an echo in here. This is one giant car, with eight seats available for the keen or foolhardy to squeeze themselves into. If you’ve got all eight deployed, the boot space starts at a reasonable 349 litres. Kick out the three in the back row and flip them up to the sides of the boot and you have 710 litres, although that figure is slightly down on what it could be as the seats don’t stow neatly away under the floor.
Getting the third-row passengers out is a bit of a chore, because the middle row needs a hefty shove to move, while folding the third row jump seats is a power-assisted affair. The middle-seat passenger in the third row is hugely unlikely to be comfortable no matter their size, but the headroom is good anywhere you choose to sit, and the second row has heaps of legroom.
Scattered throughout are cupholders - I counted seven - and you get bottle holders in the doors. All three rows should be reasonably comfortable, with vents supplying climate-controlled air to each and everyone, and the middle row has its own set of controls.
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.
When you’re knocking on the door of $170,000, “good value” is relative. You’ll be pleased to hear, however, that the LX 570 S is properly loaded. You get 21-inch wheels, air suspension, comprehensive multi-terrain modes should you feel the need to get out amongst it, terrain cameras (with under-car view), variable steering, auto LED headlights, auto wipers, powered tailgate, reversing sensors, reversing camera, clearance sensors, sat nav, head-up display, power front seats, four-zone climate control, heated front seats, wireless phone charging, around-view cameras, sunroof, heated steering wheel, and heated outboard seats in the middle row.
The 12.3-inch screen is big but it’s the old Lexus system, controlled by the weird mixture of touchpad and four-way rocker switch. It’s never been a satisfactory control method and the system itself is a little cumbersome, lacking Apple CarPlay and Android Auto.
The kids in the back should be sorted, though, with an 11.6-inch HDMI-input screen on the back of each front seat, and a set of supplied headphones so that, once the kids are plugged in, you can enjoy the 19-speaker Mark Levinson stereo in peace.
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 5.7-litre petrol V8 is classic Toyota/Lexus, unstressed and unhurried, with 270Kw and 530Nm. All of this is harnessed to an eight-speed automatic and an extremely capable off-road setup that almost nobody who buys this car will ever use.
The LX 570 S will tow up to 3500kg braked and 750kg braked.
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.
The official combined cycle figure of 14.4L/100km is fairly sobering but the real world is even more so - my time with the LX 570 S yielded an indicated 18.5L/100km, which was not unexpected given I spent a lot of time in urban and suburban driving. I don’t think that figure will come as a surprise to any owner of a 2600kg-plus petrol V8-powered four-wheel drive.
The LX 570 S has twin petrol tanks (93 and 45 litres) for a whopping 138-litre capacity to swallow 95 RON fuel, which, on my figures should deliver 745km between fills.
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.
First, some key figures - the LX 570 S is 5.08 metres long, 1.98 metres wide and 1.87 metres tall, depending on the height you’ve set the air suspension. It is Quite Large. Yes, cars like the Mazda CX-9 are as long and the Hyundai Palisade is nearly as tall, but given the LX’s humble origins, it just feels really, really big, and it looks it, too.
That feeling is not helped by oddly heavy and slow steering. The latter quality is a result of its off-roading abilities, but you can’t help but wonder if the variable-ratio steering couldn’t be made a bit quicker for town use. The S in the 570 S also adds sportier dampers front and rear, which do the ride quality few favours. Smooth roads are fine, of course, but concrete roads induce a weird porpoising movement that some air-suspended Land Rovers get, and it’s not particularly pleasant, although if you don’t use one of those roads, you won’t notice.
It's obviously a tricky machine to park and get around tight inner-city back streets. Our narrow suburban street posed a challenge when turning in and out of our narrow driveway with cars parked either side. And I did wonder about the strength of our driveway, given the heft of the LX.
I'm not going to pretend I enjoyed driving the LX, but it’s not bad to drive. You’re always aware of the sheer size and weight of the thing, though, as well as the conspicuous consumption of the very smooth and very agreeable V8. The engine does its best to shift the huge weight and the transmission is beautifully calibrated.
Once you’re on a motorway, progress is quite regal, too, so trips away in the LX will be supremely comfortable, even if you hit the busted-up dirt roads I accidentally ended up on.
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.
The LX has 10 airbags, ABS, stability and traction control, forward AEB (with pedestrian detection), auto high-beam, lane-departure warning, blind-spot monitoring, rear cross traffic alert and trailer-sway control.
The LX does not have an ANCAP safety rating. Its LandCruiser twin was last tested in 2011, so that’s not exactly relevant, given the huge rule changes and improvements in safety equipment since then.
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.
Lexus offers what I think is a unique four-year/100,000km warranty along with four years' roadside assist.
Capped-price servicing weighs in at $495 per service, almost $3000 over six services, and you'll be back at the dealer every six months or 10,000km before leaving with a loan car. Or the dealer will come and fetch the car from you and then return it freshly cleaned. Nice.
LX owners also get access to Lexus Encore Platinum . This generous program includes Lexus on Demand (you can book another Lexus - such as an LS or an RC F if you’re feeling racy - four times per year at some airports or dealers) and eight valet parking vouchers for some Westfields and Chadstone in Melbourne, all booked through the Encore app. There’s also a bunch of benefits inherited from the standard Encore program.
