What's the difference?
As far as clichés go, attempting to make “a silk purse from a sow’s ear” couldn’t be more apt than when contemplating the original NX of 2014.
What was essentially the Lexus-fication of the vocal, fidgety and thirsty old Toyota RAV4 may have worked a treat sales-wise, but proved trickier when assessed against the lens of a BMW X3, Audi Q5 and Volvo XC60 rival.
The earliest NX just wasn’t refined enough.
This was especially true following the reborn RAV4 arrival in 2019, proving to be embarrassingly more competent – even compared to most luxury midsized SUV alternatives.
Now, finally, the NX redesign has followed suit, moving on to a variation of the Toyota’s stronger, quieter and more advanced TNGA architecture (dubbed GA-K) as a starting base.
Speaking of which, let’s dive straight into the least-expensive version, the NX 250 Luxury 2WD auto, to find out if the most popular Lexus model in Australia has finally found its mojo.
Big, seven-seat 4WDs mean big, thirsty engines, right? Well, not anymore.
Meet the 2024 Isuzu MU-X, the top-selling D-Max ute's SUV sibling. And what’s ‘new’ for 2024? Well, only one thing, really. But it’s pretty important.
That one thing is the option of a smaller 1.9-litre turbo-diesel engine, joining the existing 3.0-litre option, which the brand promises will reduce fuel use without overly reducing capability.
So, is it a worthy addition to the range? Let’s find out, shall we?
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.
So, engine aside, not much new for the 2024 MU-X, but I can confidently say this: if you’re not towing big loads all of the time, then the 1.9-litre turbo-diesel won’t just save you cash at the dealership, but at the service station, too.
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.
If you like the look of the 2023 Isuzu MU-X, then boy have I got good news for you, because the changes to the 2024 model occur under the bonnet, and nowhere else, really. That means you get the same simple, boxy exterior design, which emphasises capability over fanciness.
Yes, the MU-X design is more dependable than daring, but I reckon it works, with the three-row SUV cutting a fairly handsome figure, even if it is yet to receive the design tweaks just rolled out on the updated Isuzu D-Max.
Inside, though, it definitely presents as a little utilitarian, with some plastics that feel like they could survive a nuclear blast, and the 7.0- and 9.0-inch central screens both feel a little underwhelming by modern standards.
It all feels very comfortable and hard-wearing though, which is probably every bit as important, given the MU-X’s target market.
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.
Practicality has always been a sizeable MU-X perk, regardless of the engine.
That starts with seven seats, and a back row where actual full-size humans can spend time — and there are not many three-row SUVs you can say that about.
I’m 175cm tall and while I wouldn’t pick row three as my first choice, I’d happily sit back there for short hops.
The middle row, too, is pretty spacious, though it is lacking in a few creature comforts, with just the air-con vents (but no temp controls) and a couple of USB ports to keep you company.
And remember when I said the brand was promising the 1.9-litre engine wouldn’t cost much in terms of capability? Well, Isuzu says the braked towing capacity for models fitted with the smaller engine is 3000kg, while the payload figure increases — now up to 735kg — mostly because the new engine is about 70 kilos lighter. Models fitted with the 3.0-litre turbo-diesel are still rated to tow 3.5-tonne.
The MU-X stretches 4850mm in length, 1870mm in width and 1815mm in height and it sits on a 2855mm wheelbase, which means while there’s plenty of cabin space it’s not too ridiculous to park.
You’ll find 311 litres of boot space with all three rows in place, growing to 1119 litres with the second row folded flat and 2138 litres with just the front two seats in action.
Every MU-X model will offer at least 800mm in wading depth and 230mm ground clearance, too.
Priced from $60,800 (all prices are before on-road costs), NX 250 Luxury equipment levels are – in a word – generous for an entry-level proposition. In fact, we thought our test vehicle arrived jam-packed with options, but what’s in the photos is standard fare.
There’s no scrimping on safety, for example, with eight airbags, autonomous emergency braking (AEB), front and rear cross-traffic alert, blind-spot monitor, lane-keep and steering assist, adaptive cruise control, LED lights with auto high beams and Safe Exit Assist – which won’t allow doors to open if vehicles or cyclists are whizzing by and in danger of being struck. Clever.
The NX 250 also scores keyless entry/start, a 9.8-inch touchscreen featuring ‘Hey, Lexus’ voice control, sat-nav, Apple CarPlay/Android Auto, digital radio, powered steering column adjustability, electric front seats with heating, dual-zone climate control, a powered tailgate and 18-inch alloys running on 235/50 runflat tyres (so no spare wheels whatsoever).
About the only thing we’d like is a smartphone charger, though that’s available as part of a $3000 Enhancement Pack 1, which also throws in a sunroof and kick-sensor activation for that powered tailgate. All for under $64K. Job done.
This is provocative pricing. A base Genesis GV70 RWD starts at $68,500, a Q5 35 TDI diesel FWD costs from $68,350 or nearly $73,000 for the quattro petrol AWD – as does XC60 Plus B5 AWD, an X3 sDrive20i RWD is $76,600 and a GLC 200 RWD is now from $77,305.
Even with the Lexus’ EP1 box ticked, they make the NX 250 seem like conspicuously good value for money.
You’ll find luxuries like leather, adaptive headlights, instrumentation head-up display, a larger touchscreen, vented seats, surround-view camera, premium audio and 235/50 R20-sheathed 20-inch alloys in the bestselling 350h hybrid grade, in either swishier Sports Luxury or racier F Sport grades; both begin at $73,100, AWD adds $4800 and another (rear-sited) electric motor, while that price also covers the rapid and non-hybrid 350 Turbo AWD F Sport.
The flagship NX is the 450h+ F Sport AWD plug-in hybrid electric vehicle (PHEV) from $89,900. The company’s (and Toyota’s) first such tech for Australia.
All NXs include Lexus’ ‘Encore’ aftersales subscription program offering myriad offers and services including “free” car rental.
It has always been a value-packed proposition, the MU-X, and nothing much has changed for 2024, especially if you’re shopping for the smaller engine option. Be warned, though, there are price jumps for the carryover 3.0-litre turbo-diesel in most grades.
As usual in the ute-based SUV space, the complexity of trims and powertrains can be a little confusing, but the short version is the MU-X can be had in three trim levels, with the 1.9-litre engine offered on two of them, the LS-M and LS-U.
The LS-M opens proceedings with 17-inch alloy wheels, LED headlights, black sidesteps, keyless entry, cloth trim inside, a 7.0-inch central screen with Apple CarPlay and Android Auto and air-conditioning.
The LS-U then adds 18-inch alloys, roof rails, a leather steering wheel, a bigger 9.0-inch central screen, dual-zone climate control and a powered tailgate.
Finally, the flagship LS-T gets 20-inch alloys, leather seats that are heated in the front and remote engine start.
All 4x4 models are plenty capable, too, with '4x4 Terrain Command', '2-High', '4-High' and '4-Low', a rear-diff lock and a 'Rough Terrain' mode which helps with grip and traction on slippery surfaces.
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.
Let’s focus on the new engine option here, with the 1.9-litre turbo-diesel delivering 110kW and 350Nm. They don’t sound like massive numbers, but Isuzu makes the point that the torque delivery is wide, with maximum grunt available from 1800rpm to 2600rpm, and 300Nm available from 1550rpm to 3700rpm, meaning there’s power there when you need it.
The new engine pairs with a six-speed Aisin tramsission and delivers power to two or all four wheels.
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.
Another perk of the smaller engine is a smaller fuel bill, with the 1.9-litre turbo-diesel promising to drink 7.4L/100km on the combined cycle - almost a litre less than the 3.0-litre 4x4 model, which is more like 8.3L/100km.
Emissions drop, too, with the smaller engine rated at 196g/km of C02 combined, compared with 220g/km on for the 3.0-litre 4x4 model.
Impact on the hip pocket? Well, fewer trips to the service station for one. Isuzu says the 80-litre fuel tank should deliver almost 1100km of driving between refills.
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.
First things first, you can absolutely tow with the smaller MU-X engine. In fact, we attached a load weighing close to its 3.0-tonne maximum and the Isuzu just hunkered down and got to work.
It must be said, though, it’s nowhere near as effortless as when you have the bigger 3.0-litre turbo-diesel engine up front, which dispatches heavy loads clinically and easily.
The smaller option has to try harder and rev higher, and while it’s easy enough on downhill runs or flats, it’s noticeably slower when heading up hill.
It does demand the question of how often you’ll be attaching close to its rated maximum on the towball, though. If it’s often, the bigger engine is definitely for you. But if it’s occasionally, or your tow loads are lighter, you can definitely make do with the 1.9-litre option.
On the road, the 1.9-litre engine’s power delivery is actually pretty well suited to the MU-X. It’s not fast, of course, but the width of the torque band helps deliver grunt when you need it (to a point) especially in the low-end, and I reckon the whole experience is a bit smoother and quieter than with the bigger engine, too.
You are missing some of that effortless grunt, of course, and you still can’t escape the usual diesel noise that permeates the cabin, but the lower fuel use for lower power feels like a fairly decent trade.
It won’t be for everyone, and cross-country travellers and towers will no doubt go for the bigger unit, but for everyone else the 1.9-litre is a pretty sensible option.
Tested in July, 2022, the latest NX range delivers a five-star ANCAP crash-test rating. It managed high scores in all four categories: Adult, Child and Vulnerable Road User protections, and Safety Assist technologies.
You’ll find eight airbags (providing coverage to all outboard occupants, also taking in dual-front occupant knees and centre item to stop lateral head strikes).
The AEB system with intersection assist works between 5-80km/h for pedestrian and cyclist detection and works day and night, while the car-to-car protection works between 5-180km/h.
Then there’s lane-tracing, lane-keep and steering assist, that works between 50-200km/h, as well as blind-spot monitoring, adaptive cruise control with stop/go functionality, auto high beams, road sign recognition, front as well as rear cross-traffic alert, reverse parking cameras, all-round parking sensors, tyre pressure monitors and Safe Exit Assist – which won’t allow doors to open if passing cyclists or pedestrians are in danger of being struck.
There’s also Intersection Turn Assist, providing early brake activation if required, Emergency Steering Assist (extra steering assistance to help keep the vehicle in its lane) and Emergency Driving Stop System.
As with most new vehicles nowadays, anti-lock brakes with brake-assist and electronic brake-force distribution is also standard, along with stability and traction control systems. Lexus provides three rear-seat child-seat tether anchorages and two ISOFIX latches, fitted to the outboard positions of the back bench.
Full credit to Isuzu here for fitting every MU-X model, including the cheapest option, with its full safety kit, which starts with eight airbags in the cabin.
From there, the active stuff kicks in, with the MU-X featuring AEB, 'Forward Collision Warning', adaptive cruise control (with 'Stop and Go'), traffic sign recognition, lane departure warning, 'Lane Departure Prevention', lane keeping assist, 'Emergency Lane Keeping', blind spot monitoring, rear cross-traffic alert and 'Trailer Sway Control'.
The MU-X has a maximum five-star ANCAP score from testing in 2022.
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.
Every Isuzu MU-X model gets a six-year, 150,000km warranty, as well as five years of capped price servicing, and up two seven years of roadside assistant.
The service are 12 months or 15,000km, and each service costs $449 per year, or a total $2245 over five years.
