Lexus NX450H+ vs Kia EV9

What's the difference?

The NX 450h+ Luxury combines high build quality and upmarket looks with plug-in hybrid convenience/performance/economy and numerous luxury appointments. It’s a competent all-rounder that's difficult to fault and clearly meets the needs of many prestige mid-size SUV buyers.

The Kia EV9 GT-Line earns some serious family points with its practical and luxuriously appointed cabin. Each row enjoys ample amenities and space and you can’t discount the ability to fit five child seats!

That’s where similarities with its Carnival sibling end because the driving performance is too mixed for my liking. Some of its safety features don’t react well in real-world situations but if you’re looking for an electric car that will fit a big family, this ticks that box.

My son thinks the EV9 is really cool with the ambient lighting and two sun roofs. He also loves having his own climate control and sun-blinds, so he gives it a 10/10.

The exterior is a sculptured blend of sharp creases and flowing curves which create a sporty and sophisticated appearance that clearly appeals to many buyers.

The interior looks and feels about as spacious and airy as you could realistically expect in a mid-sized SUV, which is enhanced with the roof open and sunshine pouring in.

The boldly contrasting two-tone grey and camel interior trim in our test vehicle adds to its visual appeal although we suspect such a bold colour choice could also be a stain magnet in everyday use, particularly for young families with lots of sticky kids’ stuff onboard.

To be frank, the EV9 resembles a Lego car on steroids, but it turns heads. I’ve had more looky-loos peeking into the windows this week than any other car I’ve driven.

Once you get over the (very) square shape, there are some awesome design aspects to be had.

Like the flagship exclusive Matrix LED headlights and 'Ocean Blue Matte' paintwork that feels velvet-like under your hands. The black 21-inch alloy wheels and their aerodynamic covers look futuristic and cool.

The pronounced nose looks wide-set because of the positioning of the tall headlights separated by a strangely blank panel in the middle.

In fact, the whole exterior incorporates a slew of blank panels which reinforce the square look.

The flush auto door handles, big windows and dark roof give some cool-kid cred. The digital side mirrors are not for everyone but as a driver, you get used to them. The tech looks as though it's come straight out of sci-fi movie!

The interior is downright plush with the premium-looking upholstery and customisable 64-colour ambient lighting.

The dashboard has floating panels which create a cool 3D effect and even the badge on the steering wheel is illuminated.

There is a plethora of soft touchpoints throughout and the black headliner helps make the cavernous cabin feel almost cosy.

Its compact dimensions of 4660mm length, 1865mm width and 1660mm height make the usual driving chores in congested urban settings, particularly tight inner-city streets and parking spaces, much easier than a full-size SUV.

With its 2050kg kerb weight and 2540kg GVM, it has a load capacity of 490kg of which up to 75kg can be carried on the roof rails using approved racks.

While almost half a tonne of load capacity may seem ample, keep in mind that the combined weight of five large adults could reach that limit before you could start loading their luggage.

It’s also rated to tow up to 1000kg of braked trailer, which would be ideal for hauling small trailers with a recreational focus like fold-out campers, jet-skis, trail bikes etc. However, Lexus does not publish a GCM figure, so for weekend escapees we don’t know how much it can legally carry and tow at the same time.

There’s more than adequate space for the driver and front passenger, along with storage that includes a bottle-holder and bin in each door, overhead glasses holder and a single glove box.

The centre console has two cupholders and a deep box with padded lid that doubles as a comfy elbow rest. You’ll also find a quartet of USB ports, a 12V socket and wireless phone charging pad.

The rear bench seat is surprisingly accommodating for tall people, given I’m 186cm and when seated behind the driver’s seat set in my position I still have sufficient knee clearance and headroom.

However, with three up, those in the centre must compete for shoulder space plus have their feet either side of the transmission tunnel and knees together between the front seat backrests. So, three adults is okay for short trips but should be capped at two for longer drives.

Rear passenger storage includes a bottle-holder and bin in each door, pockets on both front seat backrests and two cupholders with the centre seat backrest folded forward. The rear of the centre console has adjustable air vents, rear seat heating controls, another 12V socket and a pair of USB ports.

The power tailgate can open by waving your foot under the rear bumper (useful when hands are full) to gain access to the rear luggage area, which provides numerous internal hooks for securing cargo straps or nets plus underfloor storage for the charging cables and more.

This luggage area offers up to 520 litres (more than half a cubic metre) of load volume with the rear seat upright. It expands into what is effectively a small van when the rear seat is folded flat, which can carry everything from a mountain bike to flatpack furniture.

It’s large and you have ample space throughout the car. Even third rowers don’t miss out.

It feels quite van-like with the high seat positioning and extending centre console but you get a great view out of the massive windows.

The electrically-adjustable front seats are very comfortable but the mesh ergonomic headrests are a little too comfy!

The boxy steering wheel is nice to use but cut into my vision of the climate control screen from my driving position. I felt like I was looking around it a lot.

Individual storage is fantastic in all three rows. Up front you get a little pocket in the armrest and a huge shelf underneath the centre console.

The glove box is large, but curiously, has a small aperture. There are retractable cupholders in the centre console utility tray and drink bottle holders in each door.

The middle row has two drink bottle holders, four cupholders, two map pockets and a deep but narrow storage cubby at the back of the centre console.

Third rowers are not forgotten, either, with four cupholders and directional air vents to enjoy.

Amenities are great throughout the car and my son loves having the retractable sun-blinds and his own climate control in the middle row. It’s also an easy car to get in and out of, which we both enjoy!

The middle row's 60/40 split is a practical touch and they can be shifted manually or electrically with a one-touch button for access to the third row.

Speaking of which, there is an okay amount of room for my 168cm (5'6") height in the third row (if you push the middle row forward a smidge). And it doesn’t feel claustrophobic thanks to the wide windows.

If you have a pile of kids to shove in this car, you’ll be happy that this row also features two ISOFIX child seat mounts and two top tethers.

I wouldn’t want to be climbing into the third row to buckle in a kid, so reserve these seats for older kids.

The technology looks good but is simple to use which is always a good combination. There are plenty of charging options to choose from with each row getting two USB-C ports, while the front also enjoys a 12-volt socket and a wireless charging pad.

The touchscreen multimedia system is responsive and easy enough to use but the controls on this panel can be difficult to see and use. They’re not always responsive.

I like the satellite navigation and the way the head-up display pulls through the directions. There’s wired Apple CarPlay and Android Auto, too.

The digital instrument cluster is mildly customisable and easy to read. There is a little control panel on the driver’s door which houses the buttons for most of the added seat functions. But it’s hard to read as all the buttons are almost identical.

The boot is a good size when all seats are in use at 333L, which is plenty for my day-to-day errands, but pop the third row down and that jumps up to 828L.

Not as big as you might expect in a car of this size but that’s the compromise of going electric. The batteries have to go somewhere.

You do get a 52L frunk at the front, for cable storage. The loading space is level and you only get a tyre repair kit rather than a physical spare but it’s handy having the powered tailgate.

There are three variants for the EV9 and our test vehicle is the flagship GT-Line model that will cost you $121,000, before on road costs. That makes it the most expensive Kia to date, with the top-spec Carnival Platinum diesel only costing $67,580 (MSRP).

However, it’s nearest rival, the Mercedes EQS450 SUV, sits at $194,900 making the EV9 look downright cheap with the $73,900 price difference.

Yes, you could argue the badges would always offer a little price difference but Kia has made a true flagship model in the GT-Line because it is stupidly well-specified. It’s almost a case of what doesn’t it come with!

In terms of luxury appointments, occupants enjoy two sunroofs and two-toned synthetic leather upholstery. The electric front seats feature heat and ventilation functions, adjustable lumbar support and the driver gets a massage function.

The front seats have a relaxation mode, which I liken to the reclining seats in business class (someone send me on a trip to confirm!).

If you recline, add the sounds of nature feature and pop on the massage function, it’s like you’re in a day spa. Delightful.

The middle row outboard seats are also heated and ventilated which adds a lot of comfort and there’s a heated steering wheel, too.

Other standard equipment includes 21-inch alloy wheels, flush door handles, digital side mirrors, privacy tinted rear glass, pixel matrix LED headlights, 14-speaker Meridian premium sound and remote parking assist.

Practical features include a powered tailgate, extendable sun visors, retractable sun-blinds and three-zone climate control.

The technology is upmarket with dual 12.3-inch digital screens covering instrumentation and multimedia. There's also a 5.0-inch ‘quick-look’ climate control panel. A full tech run-down will come later.

The sophisticated PHEV drivetrain with electronic AWD comprises a 2.5-litre four-cylinder petrol engine that delivers 136kW of power and 227Nm of torque to the front wheels through a Continuously Variable Transmission (CVT).

There’s also electric motors front and rear, fed by an 18.1kWh lithium-ion traction battery that can provide limited electric-only driving range.

The front electric motor, which assists with driving the front wheels through the CVT, produces 134kW/270Nm while a smaller one exclusively drives the rear wheels with 40kW/121Nm. Although the combined output from these three power sources is 310kW, Lexus claims a total system output of only 227kW to optimise efficiency and reliability.

The petrol engine and electric motor outputs are electronically synchronised and traction is continuously monitored to automatically vary the amount of power being sent to the front or rear wheels to optimise stability and traction in all conditions.

There’s also a choice of drive modes comprising 'Normal', 'Sport' and 'Eco' and paddles on the steering wheel allow manual shifting of the CVT 'ratios' for a more engaging drive, or to increase the regenerative braking effect (like using lower ratios on descents etc).

Several operational modes can also be selected including electric-only driving (we covered 60km on one full charge and 56km on another) and two modes of hybrid driving, plus battery charging while driving courtesy of the petrol engine which during our test charged the battery from near zero to 100 per cent in 56km.

There’s also external plug-in charging of course. At home we used the three-pin domestic wall socket compatible 10A charger/AC Type 2 cable supplied with the vehicle, which took about six hours (at a tiny 2.3kW) to charge from 35-100 per cent.

The EV9 GT-Line is a pure-electric AWD with dual motors, one located at each end of the car, producing a maximum power output of 283kW and 700Nm of torque. It has a lithium-ion battery with a big capacity of 99.8kWh.

Overall, the EV9 GT-Line is powerful and capable of sprinting from 0-100km/h in just 5.3 seconds. That’s impressive for such a heavy car with a 2500kg (braked) towing capacity.

Lexus claims average combined consumption of only 1.3L/100km, achieved in ideal lab conditions which is largely irrelevant. When we stopped to refuel after 424km of real-world testing, which included our usual mix of suburban, city and highway driving and switching between the different modes (including 116km of electric-only driving), the dash display was showing 5.7L/100km.

That was close to our own figure of 5.4 calculated from fuel bowser and tripmeter readings, so based on our test consumption and depending on the mix of drive modes used, you could expect a realistic driving range of up to 1000km from its 55-litre tank which prefers 95RON premium petrol.

It's a hulk of a thing to have to move around and the motors perform brilliantly, but my energy cycle figure surprisingly came out at only 21.4kWh, after mostly open-road driving.

The official combined energy cycle is 22.8kWh, so that's a solid result.

The driving range is up to 505km, which takes the sting out of any range anxiety.

The EV9 features a Type 2 CCS port as well as an 11kW AC charger and you can get from 10 to 100 per cent in just over nine hours.

On a 50kW DC charger, you’d see that time drop to just 83 minutes to get from 10 to 80 per cent and it will shrink to 24-minutes on a 350kW charger.

A cool feature is the vehicle-to-load capability, so you can charge and/or power larger appliances on the go. Hello camping!

The cabin is what you might call ‘cosy’ for tall people like me (186cm) but there’s still adequate room to find a comfortable driving position.

The ride quality is noticeably firm, which contributes to its sporty feel. The steering is nicely weighted with good response and braking is reassuringly strong.

Acceleration in full-electric and hybrid modes is brisk but not exceptional and about what you’d expect from this powertrain, which engages the rear electric motor for standing starts and other situations to ensure all-wheel drive traction is being deployed when you need it most.

We sampled the different drive modes, with 'Sport' providing a more engaging feel (particularly when manual shifting using the paddle shifters), 'Eco' producing a more subdued response to optimise range and the default 'Normal' providing a pleasant compromise.

Even so, despite its technical wizardry and generous choice of driver preferences, we reckon most daily driving owners would simply plug-in and charge each night, start off in electric-only mode and if needed continue in ‘Normal’ hybrid mode.

Strangely for a large SUV, this car feels most at home in an urban environment. It’s in the city where it feels nimble and easy to manoeuvre. Zippy even, and you don’t notice it’s size.

But it’s a different story on the open road. 

At higher speeds there is a lot of movement in the body and thanks to its floaty suspension the amount of roll in corners starts to make it feel cumbersome.

It has the power to handle mountain driving or overtaking, but remains a bit unsure of itself in these situations.

The steering is responsive and concise, which makes for a nice driving experience in the city and navigating a car park.

The cabin gets very little noise thanks in part to sound-absorbing acoustic glass and foam in the tyres. It makes for a fairly pleasant journey overall.

As a passenger, though, I began to suffer motion sickness thanks to the digital side mirrors! Not an issue when I’m driving, but even my husband, who has an iron stomach, commented on how distracting they are.

It’s nice having a column shifter, as it helps open up the storage in the centre console but it can make pressing the push-start button a bit awkward.

The EV9 has a decent 12.4m turning circle and is relatively easy to park. The 360-degree view camera system is clear and I love having the front and rear parking sensors on this big boy.

But to access the front camera, you have to be in Drive. You can’t select it on the touchscreen, which is a pain when you’re manoeuvring into a tight space.

If you’re not confident, the EV9 also features an updated park itself feature which means you can park it remotely from your key fob. 

The EV9 has an extensive safety list and the blind-spot view monitor, which pops a video feed of your blind spot onto your dash, is a stand-out feature.

Standard safety items include blind-spot monitoring, lane departure alert, daytime running lights, forward collision warning, side collision warning, rear-cross collision warning, rear cross-traffic alert, intelligent seatbelt reminders, a 360-degree view camera system, as well as front and rear parking sensors.

There are other items but I need to call out their sensitivity issues.  

The driver attention monitor doesn’t always activate when you have sunglasses on and alerts you via multiple warning sounds and alerts on the instrument cluster.

The lane keeping aid is rather aggressive, which makes for a jerky on-road experience, and the adaptive cruise control with stop/go functionality isn’t nice to use.

Even on the shorter distance setting, it slows down way too fast when approaching a car in front.

Also, annoyingly, this model features all the warning chimes and alerts that are linked to the traffic sign recognition tech.

Go over the speed limit by one kay, chime. Enter a school zone, several chimes. If the speed sign changes, chime. If the traffic sign changes, you guessed it, CHIME.

Suffice it to say I don’t like this feature.

There's an option in the car set-up menu that turns off the warning sounds but keeps the important sign information. However, it's not permanent and has to be selected every time you turn on the car.

In better news, the Kia EV9 has just been awarded a maximum five-star ANCAP safety rating and features nine airbags which includes curtain airbags covering all three rows and side chest airbags for the second row.

Usually, you only see side chest airbags on the front row, so this is great! It also sports a front centre airbag to protect the front row from head clash injuries.

The EV9 has autonomous emergency braking with car, pedestrian and cyclist detection as well as junction turning assist.

It's operational from 10 to 80km/h but surprisingly, the car-to-car avoidance is only operational from 10 to 60km/h.

That upper speed figure usually sits closer to 160km/h. Unless there is a typo on ANCAPs website…

Families will rejoice that there is a total of four ISOFIX child seat mounts (two in the middle row and two in the third row) plus a total of five top-tether anchor points.

The car is large enough to accommodate five child seats and there’s plenty of room for front passengers when a 0-4 rearward facing child seat is installed on the middle row.  It’s pretty much a people mover at this point!

Comes standard with a five years/unlimited km warranty. Same applies to the lithium-ion traction battery, which is eligible for additional warranty coverage of up to five years (so 10 years in total) based on annual inspections.

Scheduled servicing is every 12 months/15,000km, whichever occurs first. Capped pricing, which applies to the first five scheduled services up to five years/75,000km, totals $3225 or an average of $645 per service.

The EV9 comes with a seven-year/unlimited km warranty, while its battery is covered for seven years, 160,000km. It’s normal to see an eight-year battery warranty term for EVs, though.

You can pre-purchase a three-, five-, or seven-year servicing plan, priced at $706, $1351 and $1997, respectively.

The seven-year schedule costs an average of $285 per service, which is good, but servicing intervals are more in line with a fuel-based car at every 12 months or 15,000km, whichever occurs first.
