The Lexus NX450h+ was the Japanese luxury brand’s first plug-in hybrid vehicle (PHEV) to arrive in Australia when it was launched here in 2022, and there’s been plenty of activity around the pioneering electrified mid-size SUV since then.
Exceedingly high demand and supply constraints led Lexus to suspend NX450h+ orders in early 2023, after the model had recorded a respectable 230 sales in 2022, contributing to a total of more than 1000 electrified NX sales in the same year.
Orders re-opened in late 2024, after Lexus secured a healthy supply of its plug-in NX to satisfy anticipated demand in the coming years.
The result is the 2025 Lexus NX450h+ F Sport on test here, which has received minimal changes since its initial unveiling. It’s currently the most expensive NX you can buy, but you’ll soon be able to get a plug-in NX for much less when Lexus introduces the cheaper NX450h+ Luxury variant later this year.
For now, the F Sport continues to serve as not only a flagship model grade but also a glimpse into what Aussies could be offered when the next-generation Toyota RAV4 arrives in 2026, bringing PHEV power to the nation’s top-selling SUV for the first time.

This is because the NX and RAV4 share the same platform and some powertrains, so there are many similarities found underneath the dolled-up face of the Lexus. There’s a benefit to employing the same underpinnings as Australia’s favourite mid-size SUV, but they still need to sold to potential buyers of the more luxurious PHEV, which lacks the public awareness of the RAV4.
The NX has long been one of Lexus’ best-selling models, but does PHEV power do it any favours?
How much does the Lexus NX cost?
The NX450h+ is currently the sole PHEV version of the NX and sits at the very top of the model range, priced at $95,900 before on-road costs.
| Model | Price before on-road costs |
|---|---|
| 2025 Lexus NX250 Luxury 2WD | $63,400 |
| 2025 Lexus NX350h Luxury 2WD | $71,600 |
| 2025 Lexus NX350h Luxury AWD | $76,400 |
| 2025 Lexus NX350h Sports Luxury 2WD | $79,100 |
| 2025 Lexus NX350h F Sport 2WD | $79,100 |
| 2025 Lexus NX350 F Sport AWD | $79,343 |
| 2025 Lexus NX350h Sports Luxury AWD | $84,900 |
| 2025 Lexus NX450h+ Luxury AWD | $84,500 |
| 2025 Lexus NX350h F Sport AWD | $84,900 |
| 2025 Lexus NX450h+ F Sport AWD | $95,900 |
There are a couple of caveats to this lineup. One is that only dealer stock remains of the base NX250 Luxury, which means it’ll no longer be available once those vehicles are sold.
The other is that the cheaper Luxury version of the NX450h+ will arrive next month, and it’s expected to be a much more compelling value proposition than the flagship F Sport on test here.
For the time being, it’s best to compare the NX450h+ against other flagship PHEV mid-size SUVs, including the Mazda CX-60 Azami P50e ($81,490 before on-roads), Mitsubishi Outlander PHEV GSR ($73,970 before on-roads), and Range Rover Evoque P300e ($91,902 before on-roads).
As a baseline, the existing RAV4 range tops out at $58,360 before on-roads for the Edge AWD.

What is the Lexus NX like on the inside?
Very typically Lexus, but hardly revolutionary.
Among the more unique aspects are its door handles, which look ‘normal’ but are actually electric and don’t move when pulled. There are also the Japanese premium brand’s strange button-like ‘handles’ inside, which aren’t new but still seem like a needlessly complicated mechanism.
Comfort is a highlight inside, even with the more aggressive F Sport seats. They offer more pronounced side and base bolstering and are slightly firmer than the standard NX seats, and they’re finished in high-quality synthetic leather.
I found these seats, while certainly on the snug side, fitted my 173cm frame quite well; they stay comfortable on longer drives while being supportive enough to keep you planted around turns. The contrast between these sporty seats and the otherwise traditional SUV cabin presentation is interesting, though some may consider them unnecessary.
For now the NX’s PHEV powertrain is only available in aggressive F Sport trim, but it will have broader appeal when the NX450h+ Luxury arrives in September with a lower price.
Otherwise, all of the traditional Lexus luxuries are present and correct, and it’s nice to interact with controls like the premium-feeling leather-wrapped steering wheel – with perforated leather at nine and three o’clock.
What isn’t as nice is the lack of physical switchgear. On the steering wheel are what appear to be buttons, but they’re touch-sensitive haptic controls.
This allows Lexus to pack more functions in than the eight directional ‘buttons’ allow, as pressing the largest buttons on each horizontal spoke will change what they control or adjust. It can be confusing at first, but the fact that each function is shown on the head-up display helps clarify things.
The only real complaint is that it’ll take a few presses before the system registers you’re trying to skip a song, for example. Still, a short while living with the car will cement this to memory.
Similarly, the NX’s climate controls are almost entirely digital, except for the two temperature dials. The climate interface is permanently on and takes up the bottom portion of the infotainment display. While more finicky than real buttons, everything is still clearly labelled and easy to locate on the move.
We still wish there was some more thought put towards physical controls, as even the temperature dials feel a little doughy – something like Honda’s clicky, notchy dial action would do wonders here.
If the selection of permanent controls isn’t enough, you can also open a dedicated climate menu for more detailed info. Better yet, the entire system is unaffected by any smartphone mirroring interface.
Connectivity for both Apple CarPlay and Android Auto is wireless in the NX, and the former was generally reliable over our week with the car. Some of Toyota’s typical gremlins were still there though, with Melbourne’s toll gantries regularly causing glitches and lag.
On the other hand, the NX’s digital instrument display is tidy and functional. The digital central portion is flanked by simple meters for charge and fuel level, and there are other general lights and icons scattered around the space.
There’s also a wealth of information to be found on the central portion, which is navigable using those haptic steering wheel buttons. Some of this info is tied to drive modes, like energy consumption only being visible when in EV mode, so it’s worth playing around to find what you want to display.
In the middle of the cabin is a soft armrest, as well as several of those drive mode buttons finished in easily smudged glossy black plastic. A wireless charger is fitted here too, along with individual USB-A and USB-C ports and a strangely sized cut-out, perhaps ideal for the car’s key.
Uniquely, that wireless charging pad sits atop a sliding panel that can open to reveal a small cubby housing two USB-C chargers and a 12V outlet. You’d be forgiven for missing this, but it’s still a clever way Lexus has eked out a little more storage space.
You also get two nicely sized cupholders and a generous central storage box, alongside relatively small bottle holders in the doors. Unfortunately, leaning on the driver’s door card in our test car caused it to flex and creak badly, almost as if it needed a few more clips to secure it properly.
There was a similar clicking noise coming from the rear driver’s side door, which – annoyingly – we couldn’t pinpoint. This one seemed more like a door seal repeatedly sticking and unsticking as the body flexed slightly over bumps, if you can imagine that.
Climbing into the back is easy thanks to the car’s large doors. Once you’re inside, you’ll find the rear seats are comfortable and that there’s plenty of space that should easily accommodate taller passengers.
There are also two rear-facing air vents, albeit with no dedicated climate control panel, along with dual USB-C ports and a 12V outlet. A driveline tunnel will impact middle seat leg room, but there’s a fold-down armrest with two cupholders for when that seat’s empty.
Additionally, there are two ISOFIX anchors and three top-tether points for fitting child seats.
Boot capacity in the Lexus NX is the same regardless of powertrain, measuring 520 litres with the rear seats in place and 1141L when they’re folded down. This is slightly less than in a RAV4, which offers a minimum of 542L, but more than a plug-in hybrid Mazda CX-60 (477L).
The NX’s load floor is long, but slightly lower than the boot opening. A net on the passenger side is ideal for loose items and there’s a small amount of space under the floor, where you’ll find the car’s standard 12V battery and accessories like charging cables. But there’s no spare wheel.
The tailgate is powered and can be operated hands-free, and there are several useful hooks and tie-down points scattered around the boot itself.

What’s under the bonnet?
Lexus’ PHEV system pairs a 2.5-litre naturally aspirated four-cylinder petrol engine producing 136kW of power and 227Nm of torque with a rear-mounted electric motor that makes 134kW and 270Nm. Lexus says this electric motor “achieves EV output equivalent to a 2.0-litre engine”.
| Specifications | Lexus NX450h+ |
|---|---|
| Engine | 2.5L 4cyl petrol |
| Engine outputs | 136kW/227Nm |
| Electric motor outputs | 134kW/270Nm |

| Fuel economy (as tested) | 5.7L/100km |
| Energy consumption (as tested) | 22.9kWh/100km |
| Electric driving range (claimed, NEDC) | 87km |
| Fuel tank capacity | 55L |
| Fuel requirement | 95-octane premium unleaded |
| CO2 emissions | 29g/km |
| Emissions standard | Euro 6 |
| Braked tow capacity | 1000kg |
Our week with the car primarily involved highway driving, with the long-distance routes leading us to prioritise hybrid mode over EV-only. This contributed to our impressive real-world fuel economy – impressive on its own and also compared to its ambitious 1.3L/100km claim, which as with most PHEVs is far from achievable in the real world.
Energy consumption was still on the higher side, which is curious given our skew towards petrol power. Still, I was able to get through five days of commuting (~120km per day) with no fuel stops and only one charge for the week, with more than a quarter of a tank still to spare.

How does the Lexus NX drive?
Lexus is a premium brand, and the NX captures most of what a buyer might expect from one.
It may share its bones with Toyota’s best-seller in 2024, but this is a case where Lexus’ Midas touch has been able to bring out the best of a given platform.
As a result, the NX450h+ is exceptionally quiet on the move, with little road or wind noise able to penetrate the cabin. Granted, it may not be as refined as a $100,000-plus BMW, for example, but it’s still miles ahead of the RAV4 in terms of overall refinement.
This means it’s easy to spend an hour or two behind the wheel, which will also expose the prowess of the car’s PHEV system. To start, its relatively small battery means charging won’t take long, and you have a small selection of drive modes to choose from when you set off.
Predictably, these are HEV, EV, and Auto. The latter is the most ‘normal’, as it’ll automatically choose how power is delivered from the petrol engine and electric motor to adapt most appropriately to the driver’s demands – this will also depend on the battery’s charge.
EV mode does exactly what you’d expect, so long as charge is sufficient, but it was HEV (or Hybrid) mode where we found the most value. In this mode, the NX450h+ behaves indistinguishably from a traditional hybrid vehicle.
The petrol engine will be on most of the time, which is ideal if you have a long-distance commute with prolonged freeway driving as I do, because it preserves battery charge – roughly 80 per cent in our case – leaving enough in reserve for short-distance, EV-only urban driving, with plenty of petrol left to get home afterwards.
Surprisingly, this also had little impact on our fuel economy, which stayed below 6.0L/100km for the week. As mentioned, no extra fuel and only one charge was required for the week, since the powertrain saves fuel when coasting or at lower speeds by disengaging the petrol engine.
It’s worth noting that while Lexus claims 87km of electric driving range, the car’s computer only showed 53km with a fully charged battery. With HEV mode working as intended, this wasn’t an issue.
This may sound like a plugless hybrid with extra complexity, but we found value in being able to preserve charge for driving the NX like an EV around town, while still having the engine drive us home. More generally, well-calibrated functions like the HEV mode could make PHEV like this more appealing to people living further out of town.
Additionally, the NX450h+ is quick when you put your foot into it, since 227kW of power is nothing to sneeze at. You certainly feel it when both the petrol and electric systems are working harmoniously in earnest, which is when the body-hugging F Sport seats come in handy. That said, all that power is only there if you ask for it and it will never take you by surprise.
Supporting it is a well-balanced chassis, offering confident and direct steering and very planted road holding, making the package feel all the more cohesive.
But the sporty chassis setup also includes ride quality that we think is too firm. It’s nowhere near as plush as you’d expect from an expensive ‘luxury’ SUV aimed at families, and the added weight from the PHEV battery makes the ride, particularly at the rear, a little crashy over sharp road holes and bumps.

This applies even in Normal mode, where the suspension should be at its softest. It’s adaptive, which means engaging Sport S or Sport S+ firms the dampers up further, making the car feel more planted than it already is around turns, with heavier steering also helping to transform the NX’s dynamic experience.
Completing the NX450h+ package is a comprehensive suite of safety gear, none of which is particularly annoying to live with.
Lane-keep assist, for one, is never intrusive, and only crops up with gentle assistance and a subtle warning if you stray too close to lane markings. There’s also adaptive cruise control with lane-centring, which does a good job of following the road and keeping up with cars ahead.
All considered, the NX450h+ offers a well-rounded driving experience, with enough configurability to make it suit a wide variety of needs and tastes.

CarExpert’s Take on the Lexus NX450h+ F Sport
The Lexus NX was already a good car thanks to solid foundations it shares with the hyper-successful RAV4.
Its effective PHEV powertrain expands its capabilities from an efficiency and driveability standpoint, even if it’s more complex than the standard plugless hybrid NX alternatives.
The result is a car that presents and drives like a hybrid but offers a little more electric fortitude, providing a versatile driving experience that we were able to take full advantage of, at least for a week. It’s a well-sorted system that gives drivers enough control over energy management to feel confident without getting overwhelmed.
The interior is comfortable and a little more interesting in F Sport guise, though we still yearn for more physical buttons.
We can only pull the car up on its less-than-plush ride comfort, as well as the fact it’ll likely cost more than $100,000 once all is said and done – especially now that there’s no FBT exemption for PHEVs.
The colour palette available for the NX is refreshingly vibrant, and we think the Sonic Copper paint applied to our tester is up there with the best of them.
More importantly, we believe the NX450h+ F Sport is worthy of its flagship status, but we eagerly await the arrival of the more affordable NX450h+ Luxury variant, which should better live up to the promise of ‘premium PHEVs for the people’.
