Lexus NX vs Kia Sorento

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 Kia Sorento S diesel AWD is a solid buy option in the lower-spec realm of the market. This AWD SUV is not spectacular but it manages to be competitive and, as a seven-seater with updated technology and some good features, it does have ample potential as a daily-driving family mover.

However, if you want more safety tech and more premium accoutrements, you’re likely better off forking out the extra $10,000 or so and getting a top-spec Sorento GT-Line instead.

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 Sorento’s exterior is stunningly inoffensive. So, for anyone looking for an SUV that won’t make passers-by dry retch that’s all boxes ticked, I reckon.

The cabin feels family-friendly and functional. It's a basic but well designed space, although there’s no getting past the fact this is at the cheaper end of the Sorento line-up as its cloth seats and expanses of hard plastic remind you.

That said, chrome-like touches and faux hand-stitching go some way towards balancing out that impression.

The low-slung dashboard with integrated 12.3-inch touchscreen dominates the front of the cabin in a good way.

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.

This Sorento is 4815mm long (with a 2815mm wheelbase), 1700mm high and 1900mm wide.

As mentioned earlier, the interior is quite basic and simply designed, but with a low-key classiness about it. 

The driver’s seat is six-way manually-adjustable with a pump-action for height, so pin-pointing your preferred position is a welcome minor workout unto itself.

The front seats are adequately comfortable without being too plush – that’s fine with me – and from there driver and passenger have ready access to plenty of storage and cupholders (including two in the front, four in the second row and two in the rear seat) and charging options (including two USB charge points in the front console and one 12V power outlet behind the centre console and one in the cargo area).

My teenagers weren’t impressed at all with the fact they had to plug their smartphones into charge points at the front. Oh, the torture!

The 12.3-inch digital multimedia system has Apple CarPlay and Android Auto, both wired or wireless, and it’s an easy-to-use set-up with a crisp screen.

Air-con is a manual-controls affair, second-row passengers get air vents only (on the rear of the centre console), and third-row passengers don’t get vents or fan controls.

The second row is reasonably comfortable with room enough for head, shoulders and legs to be on the right side of comfy.

It sports a bottle holder in each of the doors, and there’s a centre armrest in the second row with cupholders for the El Grande cups of whatever almond-infused crappuccino your obnoxious screenagers are currently addicted to. 

The second row is in a 60/40 configuration, which slides, reclines and folds down flat.

The third row is in a 50/50 configuration, a split-fold flat set-up, and it's the realm of mini humans – or you could put adults back there for any trip lasting longer than 10 minutes and you’ll be hated for life.

For those interested in packing potential space, the rear cargo area offers a listed 179 litres of storage capacity; a listed 608 litres in the rear cargo area when the third row is folded away; and 1996 litres when the second and third rows are packed away.

My test vehicle this time is the Kia Sorento S diesel AWD, which sits at the bottom of the four-variant Sorento line-up (S, Sport, Sport+ and GT-Line). There is a petrol version, but the Kia Sorento S diesel AWD has a price of $53,680 plus on-road costs.

Standard features include a 12.3-inch digital multimedia touchscreen (with wired/wireless Apple CarPlay and Android Auto), a basic digital driver cluster with 4.0-inch multi-function LCD display, AEB, blind spot collision avoidance assist, rear cross-traffic collision avoidance assist, 17-inch alloys (plus a full-sized spare), LED headlights, daytime running lights and fog lights.

It has cloth seats, six-way manually-adjustable driver’s seat, manual air-conditioning, second-row passengers get air vents only (on the rear of the centre console), and third-row passengers don’t get vents or fan controls.

Exterior paint choices include 'Clear White', as well as premium paint choices (all at an additional cost) such as 'Silky Silver' (on our test vehicle), 'Steel Grey', 'Mineral Blue', 'Gravity Blue', 'Aurora Black', 'Snow White Pearl', 'Volcanic Sand Brown' and 'Cityscape Green'.

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.

This Sorento has a 2.2-litre, four-cylinder common-rail diesel engine, producing 148kW at 3800rpm and 440Nm at 1750-2750rpm and that’s matched to an eight-speed dual-clutch auto transmission.

This is a generally clever and effective combination, but there is noticeable lag to acceleration from a standing start, no matter how hard you stomp the right foot.

It has all-wheel drive (part-time with lock mode) and driving modes that include on- and off-road options.

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.

Official fuel consumption for the 2.8-litre four-cylinder Sorento S diesel is 6.0L/100km on a combined cycle. 

Actual fuel consumption on this test, from pump to pump, was 6.6L/100km. 

This Sorento has a 67-litre fuel tank so – going by that fuel consumption figure – you should be able to get a driving range of about 1015km from a full tank.

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.

As I mentioned earlier, this SUV can feel a tad lardy at times, especially from take-off, but it exhibits slightly livelier characteristics soon enough. Just don’t climb into the driver’s seat expecting a dynamic experience.

Steering has a nice balance to it and the Sorento never feels gargantuan so navigating through busy city and suburban streets is on the correct side of easy.

Ride is a bit firm, but the all-pervasive mindful peace you experience from being in such a hushed cabin tends to mostly negate any minor discomfort you may otherwise feel from clipping every lump and bump on the road.

On-road driving modes are 'Comfort', 'Sport', 'Eco' and 'Smart' and off-road modes are 'Sand', 'Mud' and 'Snow'. All of these adjust engine outputs, throttle control and transmission behaviour to best suit the terrain and driving conditions.

Niggle: The driver-assist tech is a bit abrupt and intrusive. I’ve found this to be the case in Hyundai SUVs, too.

The traffic sign recognition, in particular, is clunky, reacting to signs that don't apply at that time of day, for example school signs, or it reacts to signs that don't actually apply to that section of road. So it's regularly chopping and changing between what speeds you should be at and what speeds you shouldn't. 

This Sorento is an AWD with 176mm of ground clearance so I tested it on muddy grass, firm sand and gravel tracks. Nothing outrageous, but mildly challenging enough to make sure the all-wheel drive system can do what’s expected. And it does, seamlessly.

These off-road drive modes are, of course, no substitute for 4WD, but they are fine for when conditions become a little bit slippery. For example, if there’s been a drizzle of rain on the bitumen or the dirt track becomes a bit muddy.

This Sorento has a maximum towing capacity of 750kg (unbraked trailer) and 2000kg (braked).

The Kia Sorento has the maximum five-star ANCAP safety rating from testing in 2020.

Standard safety gear include seven airbags*, AEB (with car, pedestrian, cyclist and junction turning assist, from 5.0km/h to 85km/h; car detection up to 75km/h), as well as forward collision warning, blind-spot monitoring, rear cross-traffic alert, lane departure alert, front/reverse parking sensors and more.

*Note: the curtain airbags only cover the first and second rows.

Because this is the entry-level Sorento it misses out on such handy tech as the side parking sensors, 360-degree around-view monitor and blind spot view monitor that are found in higher spec variants.

The Sorento has five top-tether child restraint anchorage points and four ISOFIX child seat mounts (two in the second row and two in the third row).

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.

A seven-year/unlimited km warranty applies to the Sorento line-up.

Servicing intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest.

Capped-price servicing covers seven-years/105,000km and at the time of writing ranges between a low of $370 and a high of $817 per service over that period. Total cost is $3787 for an annual average of $541, which isn't particularly cheap.
