Lexus NX300 vs Lexus Lm350H

What's the difference?

The Lexus NX 300h F Sport is both a comfortable and luxurious family hauler that is held back by just a few things.

Of course, gripes like the underwhelming dynamics might not be an issue for all, but the less-than-stellar fuel economy (for a hybrid, at least), disappointing practicality and fiddly multimedia will affect all potential buyers.

However, this is balanced out by loads of equipment and premium appointments for a reasonable price, which should put the Lexus NX on your shopping list if you are keen for an inner-city premium SUV cruiser.

The Lexus LM is going to be a niche model. This was not designed to appeal to people that may have bought a Toyota Tarago back in the day, or even a Kia Carnival now.

It has a specific purpose for ferrying people around in absolute comfort and at that, it succeeds in a big way.

It’s just a bonus that it’s great to drive.

Welcome to the automotive equivalent of a business class airline suite.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

Lexus might have been known for drab and dowdy styling in the past, but the NX’s sharp aesthetic is head turning and attention grabbing in all the right ways.

Though the NX first hit Australian showrooms in 2014, after six years we reckon it wouldn’t look out of place strutting down a catwalk, and can easily hold its own in the design department against the likes of the Audi Q5, BMW X3 and Mercedes-Benz GLC.

From the front, you can’t miss the trademark Lexus spindle grille, which, with its trapezoidal shape, gives the illusion of a wider and more aggressive car.

The high-set, slender headlights also gives the NX a wide stance, while the sweeping daytime running lights and sharp bumper design give the impression that the NX is cutting through water.

In profile, the NX is characterised by a strong shoulder line, chiselled lower doors and narrow glasshouse, while the black plastic wheelarch cladding hints at its SUV status.

The black trim detailing on the tail-lights almost make it look like the NX has narrowing cartoon eyes from the rear, but the subtle diffuser and large bumper soften its look a little.

If you can’t tell, we dig the aesthetics of the NX, especially the subtle exterior features such as crystal-like front foglights and the unique side mirror design.

Step inside and those neat little design touches continue.

From the almost folded fabric-like design of the door trims to the soft-touch surfaces throughout, the NX’s cabin oozes luxury, class and quality.

The centre stack shape mirrors the front grille’s trapezoid shape, while all the buttons and switchgear have a nice heft and weight to them, and are laid out in an easy-to-use, ergonomic fashion.

Sure, look a bit closer and you might see some carryover items from lower-end Toyota models, such as the cruise control stalk but, be honest, if we didn’t point it out, would you have even noticed?

Look, people movers are not considered the sexiest of automotive body styles, but that’s changing.

The Kia Carnival and Hyundai Staria are examples of good MPV design.

And the Lexus LM steps it up again. 

It is based on Toyota’s TNGA-K architecture that underpins a bunch of Toyota and Lexus models, including the Lexus RX, and it measures a whopping 5.1 metres long and has a three-metre wheelbase.

It shares its underpinnings with the latest generation Japanese-market Toyota Alphard, which is a cult hit in Australia among the grey import set.

The front-end design is bold, with the latest take on Lexus’ big ‘spindle grille’, pinched slimline headlights and a stubby nose. 

I am a big fan of this design. It is far more than a box on wheels and it has quite a bit of presence. 

The interior design up front is modern Lexus, with a few familiar Toyota touches, and while it’s not exactly minimal, it’s still visually appealing.

Measuring 4660mm long, 1870mm wide, 1645mm tall and with a 2600mm wheelbase, the NX puts it foot firmly into the mid-size SUV class.

Front occupants can easily get comfortable thanks to seats with a wide breadth of adjustment, while drivers also get a telescoping steering wheel that automatically raises when the car is turned off for easier ingress/egress.

Generous door bins up front will swallow large water bottles and any other paraphernalia, while two deep cupholders are found between the driver and front passengers.

If you want to tuck any items out of sight though, the glovebox and centre console bin will do the job, but there is also a hidden compartment where the driver’s touchpad palm rest.

Lift up the flap and your precious valuables can be hidden away, but look underneath the flap and it doubles as a handheld mirror to check you don’t have any food in your teeth before a date.

The outer two second-row seats offer ample room for six-foot-tall passengers, and – even with the front seats in our preferred position – there is plenty of legroom in the back.

Like most vehicles, the middle seat is a bit compromised, but in the NX it feels especially narrow and uncomfortable.

This isn’t helped by the middle seat’s seat belt, which comes down from the roof and intrudes well into the backrest of the neighbouring seat when not in use.

It makes loading the NX full of passengers tricky as there is a bit of shuffling around to get all the belts in place and passengers comfortable.

Our advice? Use the NX as a four-seater and just fold down the centre armrest, which also exposes two cupholders, for extra comfort.

Other rear seat amenities include air vents and storage pockets in the doors, the latter of which will accommodate water bottles or small items.

Open the boot and the NX will swallow 475 litres of volume, which can expand to 1520L with the rear seats folded down.

Boot space is down on its rivals, with all of the German models offering at least 550L of volume.

In real-world terms, this means the NX’s boot won’t close with a large- and medium-sized suitcase sat side-by-side, but has no problem with smaller cases.

Boot space might be lacking in the NX, but the hybrid system’s batteries have to go somewhere, and at least Lexus offers up two big bag books and tie-down points.

While most of the fun happens in the second row of the Lexus LM, there is a lot to like in the front compartment.

The dash is dominated by a large touchscreen that houses Lexus’ latest multimedia setup. The logical menu and uncomplicated sub-menus ensure this is an easy system to navigate. Speaking of, the in-built sat-nav is one of the better systems I have experienced. 

Comfort isn’t just the domain of the second row - the driver’s seat is very supportive and comfortable, with power adjustment.

There’s plenty of glass including a smaller front quarter window that helps eliminate front blind spots, so forward visibility is exceptional. Rearward visibility is aided by the digital rear-view mirror that is designed to ensure privacy for second and third-row occupants. You don’t want the chauffeur spying on you while you’re sleeping, do you?

The other big tick for me is the driving position. Other people movers, namely the Hyundai Staria and Mercedes-Benz EQV, have very low window lines and it leaves you with a feeling of sitting on the car, rather than in it. I am sure it helps with extra light and it probably makes it easier for kids to see out of, but from a driving perspective, I find it a little disconcerting.

But the LM has flipped that. The front compartment is designed in such a way that it feels like a cockpit that you’re ensconced in. This helps the driver feel more connected with the car, and in the LM it feels like you’re sitting in the driver’s seat of a sporty sedan, not a five-metre bus. Very well done, Lexus.

And now to the main event - the second row.

Where to begin. Let’s start with space. Because there is so much of it. Unsurprisingly given the seating layout, there is an unending amount of head, leg, knee, bum, shoulder and whatever-else room. I can’t imagine anyone complaining about space back there.

Also, getting in and out is a breeze thanks to the sliding power doors on both sides. These can be opened from the front seat, and via several buttons in the rear.

Those captain’s seats are plush. Not quite Benz S-Class plush, but still.

They are adjustable six ways - power adjustable, of course - and they’re heated and ventilated. They recline almost flat, too, if you need a nap on the way to the country estate. And while you do that you can look up through the split sunroof, or close the shade a number of ways.

Is there a massage function? Of course there is a massage function. And it’s not bad. You can choose two settings - weak and firm.

Adding to the feeling of a business class airline seat, there is a fold-out table in the armrest, although it’s a smallish one. And there is dual-zone climate control in the rear.

There is a roof-mounted control panel for things like climate, sunshades and sunroof blinds, but much of this can also be controlled by the Apple iPhone-like devices clipped into both rear seats. These are closer to the seats, so it is easier to access than the roof.

Another function in the device is the Climate Concierge that features different modes - Dream, Relax, Focus, Energise. Depending on which one you choose, it alters the seat settings, massage, climate and lights to suit.

I love the massively wide side windows that are tinted (or privacy glass), too.

Other amenities include map pockets, knee and roof-mounted air vents and a 14.0-inch display screen that retracts from the roof and connects to an HDMI cable, allowing you to watch whatever you want.

The third row is not as appealing as the second. It is technically a three-person row, but the width and the fact that it has a sizeable gap in the centre suggests that this is best thought of as a six-seater van.

The seats are not as plush of course, so you might not want to spend too much time in that row unless you are a small child. But you do get USB-C ports, cupholders, air vents, lights, sunglasses holder, power side shades and grab handles.

Getting in and out of the third row can take a while. It’s all power adjustable, so you don’t have to lift anything heavy - but it takes a while for the second row seats to move forward and up.

With all seats in place the cargo space is limited. In fact, it’s just 110 litres.

That’s similar to what you get in a seven-seat SUV. But it did fit all our overnight luggage easily.

Drop the rear row and that expands to a maximum of 1191 litres in the 350h or 752 litres in the 500h.

All grades have a space-saver spare wheel.

From launch there will be two versions of the LM350h Sports Luxury on offer - front-wheel drive and all-wheel drive, priced from $160,888 and $165,888 before on-road costs respectively.

They both have seven seats across three rows and share the same four-cylinder hybrid powertrain, but an even more high-end version is on the horizon.

The LM500h will land in January 2024, priced from $220,888, and it adopts a newer more powerful hybrid powertrain. Something else that sets the LM500h apart is the seating layout - it is a four-seater. Behind the driver and front passenger compartment are two big captain’s chairs that recline flat if required. Decadent luxury. Or so the pictures suggest. We will have to wait until the New Year to sink into the sumptuous seats.

Given the positioning and interior layout, the LM will probably not appeal to people looking at a Kia Carnival, or who would have opted for the departed Toyota Tarago. It will, however, appeal to large families that aren’t short of a dollar, airport limo operators, and even as tourist transport.

Thankfully, there’s a substantial amount of standard gear fitted as standard in the LM.

The only difference in spec between the two 350h grades is the addition of all-wheel drive. Otherwise you’ll find keyless entry and start, front heated seats, automatic retractable side steps, power opening side doors, rear privacy glass, a pair of sunroofs, and semi-aniline or L-aniline upholstery.

Tech-wise, there is a digital rearview mirror, and a 14.0-inch touchscreen, a 12.3-inch digital instrument cluster, a head-up display, seven USB ports, a smartphone charger and a rear 14.0-inch multimedia display.

The 500h adds niceties like a separation partition with elevating and dimmable glass, that doubles as a 48.0-inch widescreen display to watch films and TV, or take conference calls with. It also gets two partition glove boxes, a pair of umbrella holders, two second-row phone chargers, a 23-speaker Mark Levinson 3D audio system and more.

In terms of rivals, there really aren’t many other luxury people movers on the market. Aside from the Mercedes-Benz V-Class and all-electric EQV, there are higher-grade versions of the Volkswagen Multivan, and the LDV Mifa 9 EV.

Propelling the Lexus NX 300h F Sport is a petrol-electric mild-hybrid powertrain, combining a 114kW/210Nm 2.5-litre naturally aspirated four-cylinder petrol engine with two electric motors – 105kW/270Nm unit for the front axle and a 50kW/139Nm unit for the rear wheels.

The total system output is measured at 147kW, which is sent to all four wheels in our test var via a continuously variable automatic transmission (CVT).

The zero-to-100km/h acceleration takes 9.2 seconds thanks to a fairly hefty 1895kg kerb weight.

There are two hybrid powertrains available. Coming next year, the LM500h combines a 2.4-litre turbocharged petrol engine and a hybrid setup, making for power and torque of 202kW and 460Nm respectively. It is all-wheel drive and is paired with a six-speed automatic transmission.

The LM350h comes with a 2.5-litre naturally aspirated petrol engine and a parallel hybrid system, offering up a total system output of 140kW and 239Nm. The 350h comes in front or all-wheel-drive guise and uses a continuously variable transmission (CVT).

Official fuel consumption figures for the Lexus NX 300h is 5.7/ litres per 100km, though we managed a 7.6L/100km figure in our week with the car.

Our driving consisted exclusively of inner-city driving for groceries and just two trips down the freeway upon collecting and returning the car due to Melbourne’s lockdown rules.

As you’d hope with an all-hybrid line-up, the LM excels when it comes to combined cycle fuel efficiency. The 350h FWD sips just 5.5 litres per 100 kilometres, while the AWD version is 5.6L/100km. The 500h is a little thirstier at 6.6L. 

Our drive was so brief we did not get to record an on-test fuel figure.

The theoretical range of the LM, considering the 60-litre fuel tank and 5.5L/100km (350h) and 6.6L/100km (500h) fuel consumption figures is about 1000km.

Though the Lexus NX might look sporty and dynamic from the outside, don’t be mistaken into thinking Lexus’ mid-size SUV is anything other than a comfy cruiser.

Steering remains light and lifeless in its default ‘Nomal’ drive mode, but even in ‘Sport S’ and ‘Sport S+’, weighting feels artificial and numb.

What this means is that the NX 300h F Sport is a joy to manoeuvre around town at low speeds, but is found lacking when the speedo climbs and the roads get a bit twisty.

Likewise, a stab of the throttle is met with a spike in revs and engine noise as the powertrain switches from its electric motor to internal combustion engine, but the expected thrust-burst never comes.

CVTs are generally tuned for better fuel economy, not a sporting drive, so it makes sense that the NX is a little more hesitant and lethargic to get up to speed, but the transmission does suffer from that ‘elastic’ feel where it can be slow to ‘shift up’ if it thinks you are wanting a sporty drive.

However, these shortcomings are especially evident when stacking it up next to the new Toyota RAV4 hybrid.

The NX is underpinned by Toyota’s MC platform, shared with the old RAV4, whereas the fifth-generation mid-size SUV that launched in 2019 is updated with a TNGA platform.

Much of our aforementioned criticisms in driving dynamics and snoozy drivetrain are fixed, or at least alleviated, in the latest Toyota RAV4, so here’s hoping the next-gen NX rumoured to break cover soon will be a welcomed step forward.

And while the current Lexus NX is certainly not the last world in SUV driving dynamics, it’s not trying to be.

As a daily runabout for the family, the NX is comfortable and predictable – just what some families might be after.

The suspension does a great job at soaking up road imperfections and little bumps you might find on your journey, helped by the comfy seats and great interior sound insulation.

What is noticeable though, is overcoming large bumps or any change in elevation at speed, where the NX 300h’s hefty weight means it takes just a touch longer to get settled again.

The cabin also feels a bit fussy from the driver’s seat, with the multimedia especially being fiddly and hard to navigate when on the move.

We reckon a rotary controller like those found on a BMW, or even better multimedia software as seen with a Benz, could go a long way in fixing Lexus’ multimedia woes.

Having said that, the system is compatible with Android Auto, and is laid out well on the widescreen, so you could easily forgo the annoying touchpad and janky software for a better experience.

As mentioned earlier, I spent much more time in the second row as a passenger than I did behind the wheel of the LM350h. But it was enough time to capture some initial high-level drive impressions.

But let’s start in the rear. The ride in the second row is comfortable - as you’d hope. Our trek from Melbourne’s inner north down to the Mornington Peninsula included a lot of freeway, which was smooth. The only thing that disturbed the peace was a chunky bridge join that caused a bit of a thump. But we were hardly disturbed. 

Back in the driver’s seat, there’s a lot to like about how the LM350h drives. First of all, it feels smaller on the road than its ample dimensions would otherwise suggest. It even feels relatively light on the road. 

After the LM, I drove a Mercedes-Benz EQE SUV that has a similar kerb weight (the Lexus is about 2.4 tonnes), and the LM felt lighter.  

The hybrid powertrain is responsive enough, offering decent acceleration from a standing start. The more potent 500h will of course be quicker.

The transition from electric to petrol propulsion is pretty smooth in Lexus (and Toyota) models these days, and the additional noise-deadening materials in the LM ensure it’s subtle.

The 2.5-litre petrol engine is really only noticeable when accelerating hard, and the CVT a slight drone, but it’s in no way unpleasant. 

Otherwise it’s a superbly refined and quiet cabin on all but the absolute worst road surfaces. Whisper quiet power windows adds to that feeling of luxurious refinement.

Given the brief time behind the wheel, we didn’t get to test the handling capability of the LM, so that might have to wait for a review in the New Year. 

The steering is heavily weighted and doesn’t feel overly responsive, but it’s perfectly suited to this sort of vehicle.

That supple ride we experienced in the rear was also evident behind the wheel.

This was especially impressive on a couple of pock-marked peninsular back roads. The ride is also much more compliant than the Mercedes-Benz EQV I tested early in 2023.

The LM is yet to be crash tested by ANCAP, and it is unclear if it will be given the fact that it’s a niche model. However, as with other current Lexus models, it has a long list of standard safety gear.

The safety suite, including intersection assist, and a pre-collision system with vehicle, pedestrian, bicyclist and daytime motorcyclist detection.

It also comes with emergency steering assist, full-speed radar cruise control, ‘Curve Speed Reduction’, ‘Lane Trace Assist’ with lane-departure alert, automatic high beam, ‘Road-Sign Assist’ (speed signs only), ‘Emergency Driver Stop System’, a blind-spot monitor and rear cross-traffic alert.

Like all new Lexus vehicles, the NX 300h F Sport comes with a four-year/100,000km warranty, along with roadside assist over the same period. A six-year anti-corrosion is also part of the aftersales assurance package.

Scheduled service intervals are every 12 months/15,000km, whichever comes first.

The first three years/45,000km of scheduled servicing is capped at $495 for each annual service, which falls under the brand’s Encore service that also entails pickup and delivery of the NX, loan car, and wash and vacuum.

Lexus ownership also means owners will be access to exclusive events, dinners and drive days, as well as promotions from partner hotels.

Although servicing costs are relatively cheap for the first three years, Lexus’ four-year/100,000km lags behind luxury brand leaders Mercedes-Benz and Genesis, who both offer five-years/unlimited kilometre assurances.

When you buy a Lexus, you get a bit more than a car. The brand has a customer loyalty program - Lexus Encore - and depending on what model you buy, you are eligible for some pretty cool discounts, bonuses and experiences. 

There are three tiers, depending on your model. UX, NX, RX and ES fall under regular Encore, and electric models the RZ and UX300e sit beneath Electrified Benefits. But the LM, as well as the LS, LC and LX are under Encore Platinum - the top tier. 

That means access to the ‘On Demand’ program that allows access to another Lexus model for a few days or longer. So if you own an LC Convertible but need an RX for a few days to ferry people around, that’s all free. There’s valet parking service loans and more.

It also includes upgrades at Lexus partners. Our launch took us to Jackalope Hotel on the Mornington Peninsula, which is a Lexus partner, and you can get a bunch of extras here as a Lexus owner that other guests won’t get.

In terms of other ownership details, the LM is covered by a five-year, unlimited-kilometre warranty, and the servicing schedule is every 12 months or 15,000km.

Lexus is yet to announce the capped-price servicing details for LM, but it is expected to cover five years, and should be in the vicinity of approximately $700 per service.
