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?
The Toyota LandCruiser has joined the ranks of the new wave of hybrid vehicles with a powertrain that combines a 3.5-litre twin-turbo V6 petrol engine and an electric motor.
The 'i-Force Max' hybrid set-up, borrowed from the USA’s big ol’ Tundra, is aimed at improving the LandCruiser’s performance on- and off-road, rather than achieving greater fuel efficiency.
And with substantial increases in power (up 114kW to 341kW combined peak output) and torque (up 90Nm to 790Nm combined peak output) off-road enthusiasts are justifiably interested in how this unit’s on-paper impressiveness transfers into real-world efficacy.
The Cruiser has always been renowned for its prowess in the dirty stuff so will this hybrid powertrain make the classic off-road tourer a whole lot better?
Read on.
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 i-Force Max hybrid set-up is aimed at improving performance rather than fuel efficiency, but its effectiveness in that respect is hard to fathom.
Increases in power and torque are welcome, of course, but the 3.3-litre twin-turbo V6 diesel Cruiser is just as good as the hybrid off-road and with a bigger fuel tank and greater driving range.
The hybrid LandCruiser will certainly appeal to some buyers, but the lion’s share of those interested in the 300 Series are looking to tow big loads and go long distances in comfort, which is why the diesel Cruiser at this stage is the better pick of the two powertrains.
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.
Nothing of note has changed onboard the Cruiser and the GR Sport variants are all the same, inside and out, no matter which powertrain you opt for.
And that’s fine because this is a good-looking rooster.
The GR Sport is listed as 4995mm long (with a 2850mm wheelbase), 1990mm wide and 1955mm high. It has a kerb weight of 2620kg.
This 300 Series looks much the same as it did at launch in 2021: big, chunky, imposing – like me if I was wearing high heels.
As a point of difference to other Cruisers, though, all GR Sports have variant-specific badging on the grille, front doors and rear tailgate.
Inside, it’s pretty much the same story which is borne out in how comfortable and practical it remains.
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.
The LandCruiser’s cabin is a functional and comfortable space, and – no matter the spec level – it always has a sense of familiarity about it.
All seats in the GR Sport are leather-accented and comfortable and there are soft-touch surfaces throughout the interior.
The driver gets a heated and power-adjustable steering wheel and both occupants up front cop ventilated and heated, power-adjustable seats (with memory functions for the driver).
The GR Sport’s 12.3-inch colour touchscreen is easy to use, with wired Apple CarPlay and Android Auto, and there’s a wireless charging pad near the shifter.
Physical buttons and dials make operational life in the Cruiser much easier than if all functions were adjusted via on-screen controls, as is the case in some new vehicles.
There are USB and USB-C charging points up front.
There’s a cool box in the centre console and its lid can be opened from either side, so driver or passenger can access whatever is chilling within.
There’s also a powered sunroof if you’re that way inclined.
Beyond those features, there are the usual storage spaces, cupholders, receptacles in the doors for bigger bottles and other spaces for your bits and pieces.
The second-row seats are in a 40/20/40 split-folding configuration.
The GR Sport’s cargo space, when all five seats are in use, is a listed 910 litres behind the second row, somewhat impacted by the underfloor presence of the hybrid battery. That cargo area grows to 1842 litres when the second row is stowed away.
The rear cargo area of the hybrid has a 200V/1500W inverter, four tie-down points and of course, there's a full-size spare.
All in all, the Cruiser has the goods when it comes to practicality.
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.
The five-seat Toyota LandCruiser 300 GR (Gazoo Racing) Sport Hybrid sits near the top of the 300 Series line-up and as such has a price-tag of $155,990, before on-road costs.
It's worth noting the GR Sport is also available with a 3.3-litre twin-turbo V6 diesel engine at $147,090, before on-roads.
Standard features include a 12.3-inch touchscreen multimedia system, a 14-speaker JBL audio system, as well as leather-accented seats, heated and ventilated power-adjustable front seats, 18-inch alloy wheels and more.
The i-Force Max hybrid set-up is the big attraction in this package and, largely because of that new powertrain, Cruiser buyers have to cop a heftier price – just under $9000 – over the diesel variants.
As the highest off-road grade in the Cruiser line-up, the GR Sport is kitted out with front, centre and rear diff locks, E-KDSS (essentially an electronic active swaybar), and the long-time bolted-on LandCruiser 4WD heritage.
Exterior paint options include the no-cost Glacier White or Ebony, or choose from Crystal Pearl, Arctic White, Graphite, Eclipse Black or Merlot Red, each of which costs $710.
Rivals such as the Nissan Patrol Warrior (priced from around the $110,000 mark) or Land Rover Defender (from $102,000) offer similar levels of standard features, but something like the Denza B8 plug-in hybrid (kicking off from around the $91,000 mark) has a packed standard features list for much less cash.
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 big news here is the i-Force Max hybrid powertrain consisting of a 3.5-litre twin-turbo V6 petrol engine, an electric motor and a 10-speed automatic transmission.
Toyota reckons the “purpose‑built 1‑Motor Hybrid system” is designed for towing, off‑roading and heavy‑duty performance and that the additional electric motor “enhances power and responsiveness (compared with an equivalent diesel-only model), working seamlessly alongside the internal combustion engine”.
In general driving, it’s difficult, nigh on impossible, to discern the positive impact, if any, of the i-Force Max. But the 3.5-litre twin-turbo V6 petrol engine alone is impressive.
There’s no denying this Cruiser now benefits from a substantial increase in power (up 114kW to 341kW combined peak output) and torque (up 90Nm to 790Nm combined peak output) over the diesel Cruiser.
The Dakar Rally-inspired LC300 GR Sport’s 10-speed torque converter auto cleverly handles open-road driving and high- and low-range 4WDing, micro-managing power and torque to maintain a level-headed but involved driving experience.
The GR Sport has full-time, dual-range 4WD, a well-calibrated off-road traction control system, as well as front, rear and centre diff locks, so it’s almost unstoppable.
In this realm, the Cruiser holds its own against the likes of Nissan Patrol Warrior and Land Rover Defender.
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.
Official fuel consumption is 10.0L/100km on a combined (urban/extra-urban) cycle.
Our fuel consumption on this test was 13.6L/100km, which is substantially more than the claimed figure, but testing did, of course, include high- and low-range 4WDing.
This hybrid Cruiser has a 98-litre fuel tank (the diesel holds 110 litres) so, going by those fuel figures, you could reasonably expect a driving range of about 720km out of a full tank.
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.
Steering, now electric, is light but precise and this 4WD wagon feels highly manoeuvrable; with a turning circle of 11.8m it's quite nimble.
The new hybrid set-up is aimed at performance rather than fuel efficiency and as before the Cruiser remains a comfortable open-road cruiser, smoothly tapping into oodles of power and torque when required, all managed smoothly through the 10-speed auto.
This Cruiser’s on-road ride and handling are composed but it is soft rather than dynamic. Its suspension – double wishbone, independent at the front and live axle and multi-links at the rear with coils all-around – soaks up most irregularities in any road surface.
Its ventilated disc brakes front and rear brought the big Cruiser to a controlled stop during our emergency-braking scenarios on test.
When it comes to off-roading, this LandCruiser benefits from handy 4WD gear some other Cruiser grades miss out on, namely Toyota’s swaybar-disconnect equivalent E-KDSS (electronic-Kinetic Dynamic Suspension System), front and rear differential locks, and adaptive variable suspension.
The E-KDSS set-up acts like an electronic active swaybar, adjusting tension on the front and rear sway bars to suit the terrain and driving conditions.
While it’s a high-value addition on-road – tightening them for better body control at higher speeds on sealed surfaces – it gives the vehicle a lot more flexibility in terms of wheel articulation off-road, offering full stretch on the axles when tackling off-road scenarios.
This hybrid 300 Series tackled all obstacles at our unofficial testing and proving ground without any strife; its top-tier power and torque levels are consistently delivered across a broad rev range and that 10-speed auto is never caught out, scrambling through ratios to find the sweet spot.
High- and low-range gearing are solid in the 300 Series, and the suite of driver assist tech, aimed at making off-road driving easier and safer, is comprehensive: the traction control system has been further fine-tuned over previous versions, and is now even more precise in application.
The 300’s multi-terrain select system gives you the option of cycling through driving modes – for example, Sand, Snow, Mud, Rocks and Dirt – to suit the terrain. When engaged, the modes adjust vehicle systems, throttle, engine output etc to best suit the conditions, driving style and terrain.
Off-road measurements and angles are on point for a large 4WD wagon. Ground clearance is 245mm, wading depth is 700mm, and approach, ramp-over and departure angles are 32, 25 and 25 degrees, respectively.
Besides that, whether it’s being able to access 790Nm of useable torque across a broad rev range, or relying on the LC300’s well-calibrated traction control, or if you are engaging front, rear and centre diff locks, this Cruiser is an almost unstoppable off-roader in the right hands.
Even without the diff locks engaged, this 300 conquers every obstacle you drive it at, through and over.
If you plan to use this 4WD wagon for anything more difficult than dry-track 4WDing in good weather then get more aggressive all-terrain tyres to replace the standard Bridgestone Dueler all-terrains (265/65 R18).
The GR Sport’s full-size spare is mounted to the underbody but it doesn’t impact running clearance.
The 300 Series can legally tow 750kg unbraked, and 3500kg braked.
Here, the Cruiser remains true to its old-school spirit – albeit with a tech edge – in the same way the Nissan Patrol Warrior does, while something like the Land Rover Defender is more spaceship than scrub explorer.
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.
All of the 300 Series line-up, except the GR Sport, have the maximum five-star ANCAP safety rating from testing in January 2022.
Safety gear includes 10 airbags, two ISOFIX anchor points, as well as AEB with pedestrian and daytime cyclist detection, active cruise control (all-speed), lane departure alert (with brake to steer), road sign assist (speed signs only), trailer sway control and more.
Off-road driver-assist tech includes crawl control, downhill assist, hill-start assist, multi-terrain select, multi-terrain monitor with panoramic view and active traction control.
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.
The hybrid Cruiser is covered by Toyota’s five year/unlimited km warranty.
Servicing is scheduled for every 12 months or 20,000km (whichever occurs soonest) and costs are, at time of writing, $450 per appointment for the first five years or 100,000km (whichever occurs first).
Toyota Australia has more than 300 authorised service centres around the country.
