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?
You might call it six degrees of Kombi separation. Somewhere, somehow just about all of us have a VW bus lurking in our family and friends' back story. And this is the latest version of that familiar box on wheels to hit the Aussie market.
It’s the premium, sportier, AWD GTX version of the pure-electric Volkswagen ID.Buzz.
This one-box wonder hits the retro-futurist ball out of the park and we attended its local launch to explore whether what’s under the skin supports the promise of its stunning exterior.
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 only way to make this car cooler would be to add a split fold-out windscreen and a tube steel luggage rack on the roof.
It’s fast, super practical, comfortable and guaranteed to put a smile on the face of premium family buyers ready to go for something different. And that smile will extend to just about everyone who lays eyes on it. I love it.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.
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 ID.Buzz GTX is characterised by a unique front bumper with new integrated daytime running lights near its outer edges and a narrower black honeycomb grille.
GTX badging and the exterior mirror housings are finished in high-gloss black, and 21-inch alloy wheels are standard.
The rich ‘Cherry Red’ solid paint finish of the launch test car is exclusive to the GTX and it’s a fair bet many buyers will stump up the extra $4K required for a two-tone treatment, in this case with ‘Mono Silver’ as the highlight colour.
The interior is familiar ID.Buzz territory, with the long, broad dashtop pushing the windscreen and small front windows beside it into a quintessentially Kombi ‘bay window’-style design.
A 12-inch central multimedia screen sits proud of the multi-layered dash, and a slick 5.3-inch LCD instrument and car data display is fixed in front of the driver.
A black headliner dials up the sporty feel, the electric front seats are a GTX-specific design and the synthetic diamond pattern microfleece trim is highlighted by red contrast stitching and piping.
The red cross-stitching extends to the steering wheel and smile-inducing stainless steel ‘play’ and ‘pause’ symbols on the accelerator and brake pedals are retained.
The sub-zero cool exterior design manages to merge with a more restrained and practical interior perfectly. VW has solid retro form with the ‘New Beetle’ from the 1990s and this primo ID.Buzz looks amazing. It drew an instant crowd of curious onlookers every time we stopped.
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 ID.Buzz GTX is offered in shorter wheelbase variants with five- and six-seat configurations for other markets, but here it’s seven seats and long-wheelbase only.
At close to five metres long and just under two metres wide, it’s road-trip ready with heaps of breathing room for all seven occupants.
Placement of the gearshift on the right-hand side of the steering column frees up extra space in the front and there’s heaps of storage including a moveable (and removable) centre console unit between the front seats with pull-out drawers at either end, two trays in each door (the lower one offering room for multiple large bottles), a decent glove box and a fold-out dual cupholder unit.
There’s also an oddments shelf in front of the passenger, a wireless device charging slot in the dash and adjustable fold-down armrests on both sides of the front seats.
Pull the handle on the power-opening sliding side doors and the second row opens up with three seating positions offering hectares of room in all directions.
This row can be moved 200mm longitudinally if a turf war erupts with those in the third row. And storage is great with two pockets and a fold out table on each front seatback as well as huge door bins with waste baskets included. There are also adjustable vents with temperature control in the roof.
There’s enough head and legroom for adults in the third row although the backrest is relatively upright. Even access is straightforward and there are numerous storage trays, cupholders, air vents and storage slots back there.
Power across the cabin runs to two USB-C ports in the dash, another in the front passenger area and four USB-C charging sockets in the rear.
Boot space increases from a handy 306 litres with all seats up to 1340 litres with the 50/50 split-folding third row down, and 2469L with it and the 60/40 split second row lowered. That’s plenty.
And that 1.6-tonne braked trailer towing capacity means a jet ski, even a mid-size camper trailer, is within hauling range.
The power tailgate is welcome and the rear of the boot’s load platform sits above two storage boxes. But you won’t find a spare of any description back there; a repair-inflator kit is your only option. So beware, a flat could really suck the air out of this mobile family room.
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 new ID.Buzz GTX 4Motion is priced at $109,990, before on-road costs, which puts it in the same price zone as a diverse range of large, primo people haulers.
On price, it competes with three-row EVs like the Kia EV9, LDV Mifa 9, and if you stretch the price equation a little further, the Zeekr 009. But in terms of style and personality, this machine lives in a world of its own.
Maybe its VW California Beach sibling comes closest, however that van’s traditional turbo-diesel powertrain stands in stark contrast to the ID.Buzz’s pure-electric vibe.
Once you’ve crested the $100K mark, it’s fair to expect a healthy list of included features and the ID.Buzz GTX doesn’t disappoint.
Aside from the performance and safety tech we’ll get to shortly, the highlights include adaptive cruise control, auto LED matrix headlights, 13-speaker (plus sub-woofer) Harman Kardon audio with digital radio, wireless Android Auto and Apple CarPlay, three-zone climate control, a panoramic (dimmable) glass roof, 30-colour ambient lighting, power-adjustable heated front seats, heated (outer) rear seats and 21-inch alloy rims.
There’s also a head-up display, a heated steering wheel, rain-sensing wipers, microfleece seat trim, keyless entry and start, electric side doors and tailgate (the latter with hands-free functionality), ‘Ask IDA’ voice control and dark tinted windows.
That’s a strong, class-competitive value equation. Metallic or pearl effect paint will set you back $1890, the two-tone treatment is $4090 and black 21-inch alloys add $380.
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 GTX is a twin-motor AWD, the front unit generating 80kW/134Nm and the rear 210kW/560Nm. Total output is 250kW/590Nm which boosts towing capacity from 1.0-tonne in the single-motor ID.Buzz to 1600kg.
A single-speed transmission sends drive primarily to the rear wheels to maximise efficiency, the dual-motor set-up able to direct power to the front axle as required during acceleration or to manage available traction.
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 ID.Buzz GTX’s 86kWh lithium-ion battery delivers a claimed (WLTP) range of 473km and the car uses a CCS Type 3 socket. VW includes a Mode 2 and Mode 3 cable as standard.
The claimed 10-80 per cent 200kW DC fast charge time is 26 minutes, while the same top-up takes nine hours at a maximum 11.0kW AC capacity.
Claimed energy consumption on the combined (urban/extra-urban) cycle is 20.2kWh/100km (WLTP) and over several hundred kilometres of mainly B-road and freeway running on the launch we saw an average of 24.5kWh/100km, which isn’t out of order given the type of driving involved.
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.
Despite the fact that it weighs in at around 2.8 tonnes (2780kg), Volkswagen Australia says this dual-motor ID.Buzz accelerates from 0-100km/h in 6.4 seconds and on to a 160km/h maximum velocity, if you dare.
And there is always some serious oomph lurking under your right foot. Trundle along at 65km/h, pin the accelerator, and in roughly two blinks of an eye you’re doing 95km/h.
Proportionally, this car is like a loaf of bread on wheels - about as high as it is wide. And on the windy launch drive we were buffeted a bit, the car moving sideways slightly when hit with a gust. But overall, it remains stable despite its proportions. That said, some wind noise comes over the bluff nose on the freeway, but never to an alarming degree.
The ID. Buzz rides on VW’s Modular Electric Drive (MEB) platform and there’s been past criticism of the short-wheelbase versions' ride quality, but there are no such issues here.
Suspension is by struts at the front and semi-trailing arms at the rear and this GTX has had a suspension retune with particular attention paid to key components, including the dampers.
On rural roads that have seen better days, dotted with potholes, bumps and thumps, a combination of that suspension retune and the longer wheelbase helped the GTX handle it well.
There are five drive modes with Comfort the default. Eco smooths out acceleration, tapers the climate control and reduces overall power, while Sport dials up the powertrain, suspension and steering. Traction optimises the AWD system for loose or slippery surfaces and Individual allows you to cherry pick various attributes for a custom set-up.
Steering is progressive rate and you can feel it loading up nicely as you head into a corner. Not the last word in terms of road feel, but the car points accurately and turn-in is nice and progressive.
At the same time you’ve got the electric motors constantly shuffling drive between the front and rear axles, helping you out if you decide to explore the car’s sporty nature and have a crack in the corners.
Tyres are Hankook Ventus S1 Evo3 EV specials (235/45 fr - 265/40 rr) and in long, sweeping bends, taken at pretty decent speed, they grip hard. Even on coarse-chip B-road surfaces there’s a bit of rumble but it’s far from a roar.
Braking is by large (358mm) ventilated discs in the front and, believe it or not, drums at the back. A well-designed, modern drum brake can work effectively and the regenerative braking in an EV like this is a big factor in terms of washing off speed.
In terms of lower speed manoeuvres, you’ve got a 360-degree camera view as well as a reversing camera and front and rear parking sensors. If you really need some help, Park Assist Plus will get the job done for you.
In terms of ergonomics, we spent hours behind the wheel and the front seats remained comfortable and supportive in terms of lateral grip.
Speaking of grip, the steering wheel is nice to hold. And the cool little 5.3-inch instrument and car data display is clear as a bell, and the large 12-inch media screen is easy to use and working through the different screens is largely intuitive.
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 current ID. Buzz range hasn’t been assessed by ANCAP although its sister organisation, Euro NCAP, awarded it a maximum five-star rating in 2022.
As you’d expect, a full suite of driver-assistance tech is onboard including highway-speed AEB with pedestrian and cyclist monitoring, adaptive cruise, lane-keeping assist, lane-change assist, blind-spot monitoring, rear cross-traffic alert, driver fatigue monitoring and tyre pressure monitoring.
There’s also a 360-degree view and reversing camera, plus Park Distance Control incorporating front and rear proximity sensors.
The airbag count runs to seven - front, front side, curtains covering the second and third rows, as well as a front centre bag. And multi-collision brake minimises the chances of subsequent impacts after an initial crash
There are five top tethers for child restraints; three across the second row and two in the back row, with four ISOFIX anchors across both rows.
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 ID.Buzz GTX is covered by Volkswagen Australia’s five-year/unlimited-km warranty with two years’ roadside assistance included. On top of that, there’s an eight-year/160,000km warranty on the drive battery.
That general warranty is in line with the mainstream market, although it’s worth noting an increasing number are stepping up to longer terms, including 10 years.
There’s a 12-year corrosion perforation warranty and keep servicing with an authorised VW dealer and that roadside assistance support will be rolled over for another two years each time.
The recommended maintenance interval is two years/30,000km. Standard scheduled service pricing is $687 for each of the first five workshop visits, while pre-paid plans covering six, eight or 10 years represent savings of between 30 and 35 per cent on that figure, which is pretty handy.
