Lexus NX250 vs Lexus Rx450H+

What's the difference?

So, is the cheapest Lexus NX the grade you’d skip? Depends on where you live and drive.

If you’re urban based and bound, save up a bit more and go the petrol-electric hybrid; otherwise, out on country roads especially, the spirited and sporty NX 250 is more than up to the task.

Either way, though, the latest NX is finally fit to fight the other premium brands’ medium SUV efforts, head on and held up high. Welcome to big mid league, Lexus.

Ignore or underestimate at your own peril, everybody else.

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.

Lexus says that nearly one million of the original-shape NX versions were produced, so there’s no way that the brand was going to mess with the styling of the latest version. Which explains why picking new from old is a serious case of trainspotting.

But that migration to the TNGA GA-K platform has brought some benefits from a design point of view. The styling now breathes more, especially when viewed rear-on, thanks to a body that’s 20mm longer and wider, as well as a handy 30mm wheelbase stretch.

Drilling into the details, the headlights have an LED ‘tick’ motif, the corporate ‘spindle’ grille isn’t as in your face and the rear gains ‘LEXUS’ lettering spelled out, probably to accentuate stance.

Crisp and elegant, the design works well. This is a handsome machine. Looks expensive too.

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.

Though distinctively attractive and obviously well built, the previous NX was quite small for a medium-sized SUV inside, with tight rear legroom.

It also had a nonsense mouse-operated multimedia controller that was fiddly, annoying and counter-intuitive to use.

Thankfully, the new-from-the-ground-up design has rectified both these issues in the latest version.

Now the NX is properly medium-sized, and so easier to get in and out of, as well as palpably roomier front and rear. Employing the RAV4’s TNGA architecture results in a lower and roomier cabin, that benefits all in terms of packaging.

Being the entry-level 250, you might not expect much in terms of interior presentation or style, but Lexus Australia’s product planners have been deft in specifying this grade to make it look luxurious and on-brand.

Body-hugging bolstered perforated leather front bucket seats, in our example finished in a black/cream hue with orange stitching, belie the base-grade reality of the 250. This scheme is also found on the centre console, armrest and door cards, lifting the ambience no end. It looks, feels and smells expensive in here.

The only thing that seems to be missing is a smartphone charger. That's part of a $3K option pack that also throws in a sunroof and foot-operated actuation for the electric tailgate. Not bad.

Then there’s the driving position, with an electrically-operated reach/height adjustable steering column and a multi-configurable seat to help find the right spot. All-round vision is also better than you might expect, no doubt helped out by huge exterior mirrors and a large reversing camera screen.

Typical Lexus-style classy digital instrumentation, directly ahead, are positioned in such a way that you’re not really aware of/missing the available head-up display in higher grades. Though it takes a quick amount of familiarisation, all the info there is ultimately clear and easy to take in.

The same applies to the now touch-only centre screen, which has a slick rich finish and tactility, and also encompasses the climate-control display.

Along with banishing the dreaded mouse pad, kudos to Lexus for also installing physical switches or buttons for the most-used items – audio volume, temperature setting, and front and rear window demisting.

These and the simplified sub-screen menus for navigation, wireless telephony/audio streaming, vehicle diagnoses and vehicle settings amongst other features, is quickly second-nature in their accessibility and operation. And the sound system quality is great too.  

One of our very few complaints concerns the Apple CarPlay experience, which seems needlessly complicated to return to if you temporarily switch away from it to the NX’s native multimedia system. Confusing and distracting. 

Never mind. There are minivan levels of practicality at work here, from the superb and easily manipulated ventilation system to the seemingly endless storage options, that include bottle holder capability in the doors, a clever lid operation for the huge centre console and properly engineered cupholders.

Lovely lush materials of satisfying quality are further plus points.

We’re also fans of the NX’s electric door opening system with a failsafe handle, meaning you can grasp the door handle inside or out and a solenoid activated by a press in of a thumb releases the door quickly and naturally in a single action; it feels… upmarket and ergonomic once accustomed to.

Accessing the back seat is easy due to the latest model’s larger proportions. Much of the same applies out back as the front seat area in terms of quality of finish and attention to detail. Sculptured and enveloping backrests (adjustable for two reclining positions), a well-padded cushion and more-than-sufficient space for two burly adults or three smaller people means this NX is more family friendly than the swoopy exterior styling suggests.

We’re also happy to find large people-facing air vents, two USB and a 12V outlets, one-touch electric windows with that premium-car soft close mechanism, overhead LED lights, grab handles, centre armrest with cupholders, map storage behind both front seats, coat hooks and good lines of vision further enhance the appealing and comfortable back seat environment. It feels like a Lexus should.

Further back than that, after releasing the electric tailgate via either an interior button or exterior switch, you’ll find that the boot has a fairly high loading lip, but then offsets this with a long, flat floor with matching levels of appropriate-quality finishes. Another 12V plug and two bag hooks are included, along with ample lighting and tie-down hooks. There’s also a hidden deep storage compartment underneath the floor, due to the discontinuation of a spare wheel (due to runflat tyres, remember).

Capacity is rated at a fairly ordinary 520 litres, extending to 1411L with the split/fold backrests folded. You’d expect a remote actuation for the latter like Mazda wagons have had for decades, but none is found at this price point.

Note there is no solid cargo cover either, just a flexible/flimsy fabric item that’s foldable and easily stored.

Overall, though, despite of its base positioning within the NX hierarchy, the 250's interior experience is in keeping with the brand's image.

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.

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.

There are two ways of looking at this.

Yes, the NX 250 is powered by a variation of the same engine found in the humble base Camry Ascent in Australia at almost half the price. On the other hand, it’s a Toyota powertrain and everything that’s good and reliable and dependable about that. Which is not always the case with premium SUVs.

Dubbed Dynamic Force, which may imply forced-induction like a turbo or supercharger but there isn’t any, the 2487cc 2.5-litre naturally aspirated direct-injection D-4S twin-cam four-cylinder engine delivers 152kW of power at 6600rpm and 243Nm of torque at between 4000rpm to 5000rpm.

Drive is sent to the front wheels only, via an eight-speed torque-converter automatic. Tipping the scales at a pretty hefty 1705kg, it’s nonetheless the lightest NX, and manages a power-to-weight ratio of 89.1kW per tonne. That’s about the same as a GLC 200, which uses a 2.0-litre turbo petrol engine.

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.

Rated Euro6b, the NX 250 demands 95 RON premium unleaded petrol. Same as Camry, actually,

We recorded a decent 9.7 litres per 100km during our time using the NX 250 in city, urban and rural conditions, against the trip computer’s 9.5L/100km and the official combined average of just 6.9L/100km.

Note this may be so because there was a lot of fast back-road driving, as the engine loves a rev and there’s a palpable wave of power that comes on strongly between 5000rpm and 6500rpm. A bit like Mazda’s naturally-aspirated units, but just not as sonorous.

At 55 litres, the fuel tank will allow for up to 797km based on the combined average cycle between refills.

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 NX 250 truly is a tale of two cars.

Around town, it is utterly capable and benign. The 2.5-litre atmo four-pot petrol unit is a revvy, raucous sort of engine, pulling away strongly off the line, responding quickly to pressing down on the throttle, shuffling up through seven of the lower gears smoothly (top is a highway overdrive), and generally being an easy vehicle to drive.

About the only concern is how noisy the engine can become if you’re needing to accelerate hard, with a definite mechanical zing that gives the Lexus a bit of a hoon attitude. We’re also a little hesitant about using the Sport mode in built-up areas, as ratios are held on to whether up or down shifting, amplifying the loud nature of this powertrain.

Other aspects of the NX 250’s driveability around town rate highly: light yet linear steering, with a tight turning circle providing easy manoeuvrability and parking; firm yet still absorbent suspension, offering an appropriately isolating ride over most bad road surfaces; and an overall sense of sound engineering. It seems quieter than an equivalent RAV4, more importantly.

Which led us to initially conclude that, in an urban environment, you’d naturally pay the extra $3K for the NX 250 Hybrid, to eliminate that noisy engine when pushing down hard on the throttle. Easy.

However, then we ventured out on a long rural drive, a few couple of hundred kilometres from the big city. On country roads, the NX 250 really sparks up in a most compelling way.

Yes, the engine is still a bit rowdy, but as the revs rise and the needle edges near the 6800rpm red line, the Lexus just keeps on building up speed rapidly, providing an unexpectedly sporty edge. Above 5000rpm this thing still has plenty of oomph, relying on a deep well of power to really extend its legs.

It also makes sense to slot the auto lever into manual, and use the finely positioned paddle shifters. That’s when you’re most aware of the gearbox being a torque-converter auto, with defined and assertive selections. It’s a good way to feel involved in the experience too.

Actually, as a mechanical ensemble, it all comes together at speed; that light and easy steering remains relaxed yet reactive, weighing up nicely if you choose Sport. The handling maintains a fluid, connected feel, with ample levels of grip from the Bridgestone tyres.

It occurred to us that driving the NX 250 Hybrid out on rural backroads would deny the enthusiast of the base model’s lightness and agility, since the latter weighs hundreds of kilos less; the brakes are perfectly modulated instead of feeling vaguely mushy and/or trigger happy as with many electrified SUVs; and – even with the road noise being well-supressed – you’re far less aware that the atmo petrol engine is singing loudly at speed.

Plus, the ride out in the sticks, even on our craggy old test strip that would jar the bones of some other midsized SUVs, remains calm and comfortably firm. That’s real progress for the NX.

We’d appreciate a bit more nuance in the way the stability control kicks in (quite late) to catch the tail; while the driver-assist tech like the adaptive cruise control and lane-keep assist do their jobs admirably, the latter’s constant chiming can be annoying; and there's a fair amount of road-noise intrusion over coarse bitumen. Like most midsized luxury SUVs, actually. Still quieter than a RAV4, though.

No jarring faults then. Lexus has done its homework and fixed most of the things that annoyed or infuriated us about the previous generation version. Good work.

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 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.

Since the beginning of 2021, Lexus offers a five-year, unlimited kilometre warranty with roadside assistance. It used to be four years.

Service intervals are at 12 months or 15,000km, whichever comes first.

The NX also includes three years and 45,000km of capped-price servicing, with each one costing $495 – and as we’ve noticed in the recent past, that is very highly competitive pricing for a luxury brand.

Plus, there’s also Lexus’ ‘Encore’ aftersales subscription program offering myriad offers and services.

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.
