Lexus NX250 vs Kia EV6

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 EV6 Air offers comfort, a good range of features and beautiful handling for a ‘base model’, but it is a little pricey considering its competition.

Having said that, if you’re looking for an EV that will fit the family and has a stellar safety list – this is one to consider.

My son reckons the EV6 looks 'really cool' and he loves the space in the back seat.

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 EV6 is cool and fun-looking, but being the base-model does mean you get plastic rather than body-coloured mouldings around the base of the car, which highlights its grade level.

The exterior hosts 19-inch alloy wheels and a full suite of LED lights but misses out on the upgraded Matrix headlights that the higher grades get.

The exterior's swoopy curves look aerodynamic and the chunkier rear balances out the sharper nose.

The interior looks well-made, and the mix of high-end cloth and synthetic-leather materials complement the futuristic exterior aesthetic.

The dashboard is headlined by a curved panel that houses the dual 12.3-inch tech screens and the floating centre console leans into that future vibe again.

There's a nice mix of touchscreen and physical buttons to satisfy a wide audience. Overall, while it’s not as flashy as its siblings, the cabin of the Air is very pleasant to look at.

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 space in the EV6 rivals much larger SUVs and tall families will rejoice with how much leg- and headroom you get in both rows.

The comfort for passengers is pretty good, with comfortable seats in both rows that feel well-cushioned. The floor in the rear is flat, which accommodates any middle-seaters.

Being the base grade, you don’t get electric front seats, which is a bit rough for its price point but the driver’s side does get powered lumbar support, which I appreciate on longer journeys.

Individual storage is fantastic for the class and the front gets two cupholders, a drink bottle holder in each door and glovebox and middle console. There are multiple storage nooks and a utility tray on the topside of the floating centre console (sized for items like keys, wallet, phone etc).

The large shelf underneath the centre console easily accommodates a handbag and snacks for any kids in the back (or adults, no judgement).

Individual storage in the back is as good as the front, with plenty of spots to tuck away all of the paraphernalia that kids seem to attract. There are also two cupholders in a fold-down armrest, a drink bottle holder in each door and map pockets.

On the whole, my seven-year-old really enjoys being in the back seat because of the amenities and space he has. He finds the EV6 to be an easy car to get out of but we all struggle with the flush door handles! They can be terribly annoying to use as they don’t pop out on approach or when you unlock the doors. If you have your hands full and have little T-Rex hands like me, it can be awkward to open.

What isn't awkward to use is the technology! The 12.3-inch touchscreen multimedia system is quick to respond and the system itself is easy to navigate once you spend some time with it.

The 12.3-inch digital instrument cluster is semi-customisable but not as pretty in its graphics as it could be. It has two styles to choose from - white or black, and the white is a little too sterile for my liking.

The multimedia system features wired Apple CarPlay, Android Auto and built-in satellite navigation with map updates for 10 years.

Charging options are solid with a single USB-A and and two USB-C ports up front, a wireless charging pad and a two 12-volt ports to choose from. The rear enjoy a three-pin standard house port and two USB-C ports as well.

The back seat has a 60/40 split and it's handy that you can lower them from the boot with manual levers. The boot itself is a good size with 490L when all seats are in use but you miss out on a powered tailgate in this model.

The frunk storage also offers an additional 52L, which is perfect to keep any charging cables or the tyre mobility kit stored away.

The Kia EV6 Air is the base-model in a four-variant line-up but is still priced at $72,590 before on road costs.

That positions it as the most expensive option compared to its nearest rivals. The Hyundai Ioniq 5 2WD is the closest at $71,000 but the Tesla Model Y RWD base model is $7190 more affordable.

Compared to it's siblings, the Air isn’t as well-equipped with the luxury features, but it doesn’t feel basic either because the technology is top-notch.

There is a 12.3-inch touchscreen multimedia screen and a 12.3-inch digital instrument cluster, plus built-in satellite navigation, as well as wired Apple CarPlay and Android Auto. Other tech features include dual-zone air-conditioning, single USB-A port, four USB-C ports, a wireless charging pad and a full suite of LED lights.

A mixture of premium cloth trims and synthetic-leather upholstery gives the cabin a premium feel, but being the base model does mean you miss out on the upgraded sound system. The base sound system with its six speakers is sufficient for every day use.

The seating features manual adjustments, but the driver's side does enjoy powered two-way lumbar support, which I appreciate on a long journey.

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.

The EV6 Air is a single-motor rear-wheel-drive that produces a maximum power output of 168kW and 350Nm of torque.

The Air has the slowest 0-100km/h sprint time in the EV6 range at 7.3 seconds, but that’s honestly enough for my little family. It still feels pretty damn zippy when you put your foot down.

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.

Officially, you get a driving range of up to 528km (WLTP) from the 77.4kWh lithium-ion battery. However, the longest range I ever saw was 480km, which admittedly is still very good.

The EV6 Air has a Type 2 CCS port, which means you can benefit from plugging into a fast charger and the accepted voltage is a whopping 800v.

On a 50kW system, you’ll get from 10-80 per cent charge in 73 minutes and on a 350kW system, which charge time drops to just 18 minutes.

Expect it to take longer on AC charging, though. To get from 10-100 per cent on an 11kW system, it will take approximately seven hours and 20 minutes. On a standard house plug ... expect it to be on charge for around 30 hours.

The Air also has a vehicle to load (V2L) capability – meaning, it has a standard house three-pin plug port available to charge larger appliances while on the go. 

The official combined energy consumption is 16.5kW/100km (WLTP), and my usage came out at 16.02kW after a mix of open-road and urban driving this week.

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 EV6 Air handles itself really well, it's been hit by torrential rain and didn’t skip a beat.

The Air really grips the road and distributes the power through the rear wheels evenly. Even at higher speeds, there’s no wobble and it feels stable when you accelerate. 

Steering is on the right side of firm and makes the Air feel very zippy when navigating tight city streets.

There are three levels of regenerative braking available, as well as a one-pedal function called iPedal, which is probably the best I’ve sampled and I like how responsive it is in stop-start traffic. However, when using this function on hills, I still hover over the brakes as it can still roll forward a bit. 

The cabin can get really loud from road noise at higher speeds, but it seems to come from underneath the carriage, rather than through the windows. The suspension is well-cushioned but not spongy.

Parking the EV6 isn’t an issue once you get used to the rotary gear selector and the reversing camera is super clear. You get a 360-degree system on higher grades but the Air does come with front and rear parking sensors.

The Kia EV6 Air is well equipped with safety features and it's here that you don't feel like you're in the 'base model'.

Standard features include the biggies like forward collision warning, blind-spot monitoring, rear cross-traffic alert, lane-keeping aids, lane departure alert, driver attention alert, reversing camera and front and rear parking sensors.

Considering the Air is a base model, it's also great to see items like blind-spot collision avoidance, safe exit warning, rear occupant alert and haptic-feedback on the steering wheel (as an additional 'sense' warning).

I rejoiced when I discovered that the Traffic Sign Recognition technology has been tweaked to not sound or alert on every traffic sign or speed change. It still chimes in school zones, but you no longer have to go into the menu to downgrade the sensitivity! Hurrah!

The Air has AEB with car, pedestrian, cyclist and junction turning assist, which is operational from 5.0 - 85km/h but it is usual to see that top figure be well above 100km/h, so this is surprising.

The EV6 achieved a maximum five-star ANCAP safety rating from testing done in 2022 and features seven airbags, including the newer front centre airbag.

There are ISOFIX child seat mounts on the rear outboard seats plus three top-tethers. You might get lucky in fitting three skinny child seats but two fit the best and there’s plenty of space for front passengers when a 0-4 rearward facing child seat is installed too.

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 EV6 comes with a leading seven-year/unlimited-km warranty. The battery covered by a separate seven-year/150,000km term, but this is a smidge shorter than some of its rivals.

You can pre-purchase either a three-, five-, or seven-year servicing program, priced at $721, $1382 and $2045, respectively. All of which are reasonable for the class.

The seven-year program runs up to a max 105,000km.

Servicing intervals are more in line with a fuel-based car at every 12 months or 15,000km, whichever occurs first.
