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 Tundra, made in America for Americans, was launched in 1999 and since then Toyota Australia has fielded a steady stream of enquiries from car buyers and automotive media about the possibility of its full-size US pickup being available in local showrooms.
Production of RHD Tundras at Toyota’s San Antonio plant in Texas never stacked up as a viable business case for Toyota until 2015, when the Walkinshaw Automotive Group (WAG) commenced OEM-certified right-hand-drive remanufacturing of Ram pick-up trucks (and later Chevrolet Silverados) in Melbourne.
This development finally opened the door to an ‘Australianised’ version of the Tundra, which went on sale late last year after a six-year joint development program with WAG that was a world-first for Toyota.
The Tundra’s local two-model range comprises the entry-level Limited and the new top-shelf Platinum grades, with more power and torque than local ‘1500 class’ US pickup rivals. So, we recently put the fresher Premium model to work for a week, to see how it measures up from a tradie’s perspective.
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 Tundra Platinum is a good-looking and well-engineered RHD full-size US pickup which stands apart from local competitors with its unique hybrid drivetrain and unmatched power/torque outputs. However, it also comes with a conspicuously high purchase price, which given the quality of local Ram, Chevrolet and Ford competition could be a deal-breaker for some.
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.
This is a substantial vehicle with bold, bluff-fronted styling characterised by an enormous grille that has an imposing presence wherever it roams.
Toyota's TNGA-F ladder-frame chassis platform is shared with the LandCruiser 300 Series and Prado models, but the big American has a much longer 3700mm wheelbase, spans almost six metres in length (5955mm) and is more than two metres wide (2040mm). However, it’s less than two metres tall (1985mm), so it can access underground and multi-storey carparks.
It rides on double-wishbone coil-spring front suspension and a multi-link coil-spring live rear axle, with electric power-assisted rack and pinion steering and big four-wheel disc brakes.
Off-road credentials include 216mm of ground clearance, 23 degrees approach and 21 degrees departure angles – which are ample for accessing rugged worksites – while the turning circle is an expansive 15 metres.
The interior, with its panoramic sunroof, has a spacious and airy ambience, enhanced by contrasting blue stitching on its leather-appointed upholstery.
Although the cabin has a high standard of fit and finish, as you’d expect from Toyota and WAG, it doesn't look and feel quite as lavish as the sumptuous interiors found in its top-shelf US rivals. The centre console lid in particular feels too light and plasticky for a vehicle in this price range.
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 2834kg kerb weight and 3536kg GVM, the Platinum has a 702kg payload limit which is modest compared to smaller 4x4 utes with genuine one-tonne-plus capabilities.
However, it’s rated to tow up to 4500kg of braked trailer on a 70mm ball and with its substantial 7980kg GCM (or how much weight it can legally carry and tow at the same time) that would require only a small drop in payload from 702kg to 646kg to avoid exceeding the GCM. So, that’s a practical set of numbers if you ever need to tow the maximum 4.5 tonnes.
The load tub is 1660mm long, 1491mm wide and 531mm deep, with 1237mm between its rear wheel-housings allowing either a standard Aussie or Euro pallet. It’s accessed through a power tailgate, which can be operated from the driver’s seat if required.
The tub’s internal surfaces are protected by a composite drop-in liner, with handy slots moulded into each side for vertically inserting planks of wood to serve as lateral load-dividers if required.
The Platinum's tub also has unique hooded LED lighting in each sidewall, plus there’s fixed load-anchorage points front and rear at mid-height (would be better if just above floor height) and rails with adjustable sliding anchorages along the top of the front and side walls for securing taller loads.
Cabin storage includes two 600mL bottle-holders and storage bins in each front door plus a decent-sized single glovebox, a 12V dash socket and an overhead glasses-holder.
The centre console offers open storage up front including a wireless phone-charging pad, plus a pair of small-bottle/cupholders in the centre and a large lidded box at the back containing USB ports.
The large rear doors, with pull-up privacy screens on their windows, provide wide entry to the rear bench seat. There’s enough shoulder room for three adults and even tall passengers enjoy ample legroom, although those seats in the centre must contend with a transmission hump, which is absent in its flat-floored rivals.
There’s two 600mL bottle-holders and a bin in each rear door, plus large pockets on each front seat backrest and two more bottle/cupholders at the rear of the centre console, which also has controls for rear seat heating/cooling, plus USB ports and adjustable air-vents.
If travelling with two, the centre seat backrest folds down to provide a comfortable armrest and two more bottle/cupholders (that's 14 in total), so drink storage is well catered for in this cabin.
The rear seat’s 60/40-split base cushions can also swing up and be stored vertically for more internal luggage space, but there’s no storage compartments underneath as this space is occupied by the hybrid drivetrain’s battery, with large vents on either side providing it with ample ventilation.
Our only criticism of the rear seating is limited headroom for tall people, caused by a deep contour in the roof-lining to accommodate the Platinum’s sunroof.
This contour sits very close to foreheads and limits head space. So, if you have tall passengers, they might get cranky on long drives, particularly those seated in the slightly higher centre position with (like me) the top of their head pressed firmly into the roof lining.
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 recently launched Platinum test vehicle is, like its Limited sibling, available only with Toyota’s ‘i-FORCE MAX’ hybrid powertrain, which combines a 3.5-litre twin-turbo V6 petrol engine, electric motor-generator, traction battery and 10-speed automatic transmission, for a list price of $172,990 plus on-road costs.
That pricing is $17,000 more than the Limited and considerably higher than Australian premium-grade RHD rivals including the Ford F-150 Lariat LWB ($140,945), Chevrolet Silverado 1500 ZR2 ($141,500) and Ram 1500 Limited ($159,950). Note the F-150 has temporarily been withdrawn from sale in Australia due to an ADR compliance issue.
The Tundra Platinum shares numerous standard features with the Limited, including 20-inch alloy wheels (although the Platinum’s wheel design is unique) with 265/60R20 tyres and a 245/75R18 ‘space saver’ spare (to optimise its underfloor-mounted ground clearance), LED lighting, heated door mirrors, an automatic ‘active’ front spoiler, side steps, a power tailgate, a tub liner, a 3500kg towing kit and front/rear parking sensors to name a few.
The cabin has smart entry/start, dual-zone climate, front seat heating/cooling, a leather-accented steering wheel and shifter, a 12.3-inch driver’s digital instrument cluster, a 12-speaker JBL audio system with a 14-inch multimedia touchscreen and multiple connectivity including Apple/Android devices, wireless phone charging, power sliding rear glass, five USB ports and more.
The Platinum adds not only its unique black-painted alloy wheels but also a bold mesh grille design with dark chrome surround, black body detailing, tailgate spoiler and rain-sensing wipers.
The cabin gets a full-length panoramic sunroof and leather-accented trim, with the front seats equipped with 10-way power adjustment including a massage function. There’s also heating/cooling for the outer rear seats, heated steering wheel with power tilt-reach adjustment and 10.9-inch colour head-up display.
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 Tundra’s powertrain consists of a 3.5-litre twin-turbocharged V6 petrol engine that produces 290kW of power at 5200rpm and 649Nm of torque between 2400-3600rpm.
This is paired with an electric motor mounted directly behind, which produces 36kW/250Nm and draws its electrons from a 6.5Ahr Ni-MH (nickel metal hydride) battery located beneath the rear seat.
Their combined output is 326kW and 790Nm, which is more power and torque than any of its local rivals and therefore appealing for those who need to haul and/or tow heavy loads.
Its refined 10-speed torque converter automatic offers the choice of sequential manual-shifting, a dedicated Tow/Haul setting and three drive modes comprising Normal (default), Sport and Eco.
The 4WD system is part-time, dual-range with 2H (2WD High Range), 4H (4WD High Range) and 4L (4WD Low Range). There’s also an automatic limited-slip rear differential, but unlike its competitors no full-time AWD mode is available.
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.
With the Tundra’s GVM rating exceeding 3.5 tonnes, Toyota is not required under current ADRs to publish fuel consumption figures. Even so, we covered a total distance of 298km, which comprised a mix of suburban, city and highway driving of which about one third was hauling a near-maximum payload.
When we stopped to refuel, the dash display was claiming average combined consumption of 14.1L/100km, but our own figure calculated from fuel bowser and tripmeter readings was 15.8, which is in the same ballpark as mid-teen figures we’ve achieved in its six and eight-cylinder rivals.
Therefore, based on our own figure, the Tundra Platinum has a real-world driving range nudging 800km from its big 122-litre tank, which according to Toyota requires minimum 95 RON petrol.
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 side steps are set close to the sills and, therefore, a bit narrow for size 12 boots, but big handles on the A and B pillars assist climbing aboard, where you’re rewarded with a spacious driving position with multiple adjustments.
The analogue-flavoured RHD dash module has numerous physical dials, buttons and switches, which thankfully leaves minimal reliance on distracting touchscreen prompts. Some items, like the left-hand-side indicator stalk and HVAC controls, are biased towards LHD, but you soon get used to these idiosyncrasies.
Its excellent steering feel, braking response, supple but responsive four-coil ride quality and effective noise insulation are what we’ve come to expect from WAG’s extensive remanufacturing process. In the Tundra’s case, it uses many original equipment components from existing Toyota 4WD vehicles and OEM suppliers.
The V6 engine produces a meaty V8-style soundtrack, with a melodic throb at idle and a guttural roar at full throttle. From standing starts, the abundant torque gets more than 2.8 tonnes of pickup to triple-digit speeds in about six seconds, which is comparable to Ford's sporty Ranger Raptor.
The hybrid drivetrain displays excellent refinement, as it continuously and seamlessly switches between petrol and electric power to optimise performance and economy. The Tundra is also an effortless highway cruiser, with negligible tyre and wind noise at 110km/h allowing conversations at loungeroom levels.
To test its load-hauling ability we strapped just over 500kg into the load tub, which with our two-man crew equalled a total payload of 675kg that was nudging its GVM limit. The coil-spring rear suspension only compressed 50mm, leaving ample bump-stop clearance and no risk of bottoming-out on our test route.
It made light work of hauling this payload in city and suburban driving and didn’t seem to notice it had anything in the load tub on our 13 per cent gradient, 2.0km set-climb at 60km/h.
Engine-braking on the way down, in a manually-selected second gear, wasn’t as robust as expected given the assistance of regenerative braking, but the large four-wheel disc brakes were more than capable of keeping speeds under 60km/h when called upon during the descent.
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.
Like its local US competitors, the RHD Tundra does not have an ANCAP rating but comes with a suite of passive and active safety features. These include eight airbags, AEB with day cyclist detection and day/night pedestrian/oncoming vehicle detection, lane-keeping, trailer sway control, trailer back-up guide with straight path assist (makes reversing a trailer easy and safe), blind-spot monitoring, rear cross-traffic alert, front/rear parking sensors, panoramic view monitor and more. The rear seat has two ISOFIX and two top-tether child-seat anchorages.
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 Tundra comes with Toyota’s five-year/unlimited-kilometre warranty, which is class-leading.
Scheduled servicing is six months/10,000km whichever occurs first, with capped-pricing of $450 per service for the first five years/100,000km. So, that’s $900 annually, if serviced twice a year as scheduled.
Toyota currently has 275 dealers across its vast network located in metro, rural and regional areas. Toyota dealerships are also service centres.
