Lexus NX450H+ vs Kia EV9

What's the difference?

The Lexus NX450h+ F Sport is a gorgeous mid-size SUV that combines great specs and a fairly efficient plug-in hybrid powertrain. It’s a comfortable and easy ride which should appeal to a wide range of driving styles. It also looks good parked at the kerbside of a city street and with it ticking most of the boxes, it may become your new best friend.

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 NX simple looks like a scaled-down version of its larger RX cousin, so if you like that you’ll like what the NX.

It looks sweeter, though, with its smaller proportions being only 4660mm long and 1670mm high but there’s enough sharp pleating in the panelling and rear LED lights to give it a sporty edge. It’s a design that should appeal to a wide range of people.

The interior helps the NX compete against some of its flashier rivals, but the BMW X3's interior beats it hands down with the wow factor. Still, the dual-toned leather upholstery and fabrics of our test model scream understated luxury.

The perforated leather of the seats is supple underhand, but even the robust synthetic leather on the backs of the seats and some door panelling feels like the real stuff most of the time.

The dashboard components – like the air vents, displays and accents – are well integrated and seem well-built. The cockpit is intimate and plush overall, and it always reminds you that you're in the cabin of a luxury vehicle.

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.

The cabin of the NX is spacious where it needs to be for four adults to be comfortable on a longer journey, and features enough equipment to satisfy most.

Access is best at the front because of the wider door apertures and while still easy enough to get in and out of from the back, the rear wheel arch cuts into the aperture a bit.

The front seats are very comfortable with thick padding, tall side bolsters that lock you into place in a turn as well as heating and cooling functions.

The back seats are almost as comfortable as the front! However, the outboard seats offer the best under-thigh support. It is a shame that they miss out on heat functions for its grade level, though.

Storage is fairly good for the class, with lots of small item cubbies up front like a sunglasses holder, a mini drawer next to the drivers' knee and a dedicated phone holder and two cupholders. The large glove box (that can hold more than just a manual) and mid-size middle console shoulder most of the storage burden, though.

In the back you get a couple of map pockets, small storage bins and two cupholders. which is most than enough for this size of SUV.

The boot offers an impressive 520L of capacity and a level loading space makes it an easy car to slide larger gear in and out of. The little storage compartment under the floor is handy for charging cables and the hands-free powered tailgate is always handy to have.

The technology is a nice mix of easy-to-use and high-end with a responsive touchscreen on the 14-inch multimedia display. The system has built-in sat nav, wireless Apple CarPlay and Android Auto. The CarPlay was simple to set up and has maintained a steady connection with my iPhone this week.

Charging options are decent with two USB-C ports and a 12-volt socket per row, as well as a wireless charging pad up front.

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 NX450h+ F Sport is the first attempt at a plug-in hybrid powertrain for Lexus. It pairs a 2.5-litre four-cylinder petrol engine with two electric motors, one located at each end of the car for all-wheel drive. Together they produce up to 227kW of power, but Lexus doesn’t quote the combined torque figure (cheeky).

The flagship model can do a 0-100km/h sprint in 6.3 seconds and features a smooth continuously variable transmission.

Overall, it moves quickly and the shift between the electric and engine components is barely noticeable.

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.

The flagship NX has a smallish 18.1kWh lithium-ion battery and a Type 2 charging port but no CCS enhancement, which means you can’t hook it up to a fast DC charger.

On a standard AC 240-volt domestic plug port, you can charge this from 0-100% in around 7hrs 30mins. You get a great electric-only NEDC-rated driving range of up to 87km and that means you really only have to charge it every other day, which I appreciated. 

The official combined fuel cycle usage is 1.3L/100km, but you won’t really see that in the real world. After doing some longer trips mixed in with city slicking, my average real-world usage popped out at 6.5L/100km, and I averaged 20.2kWh/100km when in pure EV mode. They’re not the best hybrid figures I’ve seen for the class, but they're not too bad either.

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!

This NX feels like it has lots of power in reserve when you put your foot down and never struggles going up big hills. When it’s in pure EV mode, it’s very quiet but there’s no big fanfare when this kicks over to the traditional engine. You barely notice it until you’re on the open road travelling at higher speeds, and that’s when the engine starts to sound more growly like its non-hybrid siblings.

The steering is forgiving without feeling too light and around town, the NX is nimble and sure of itself. The suspension is on the firmer side, so you’ll hear and feel the bigger bumps, but it never feels rough.

Visibility is decent with the largish windows, and the pillars that aren’t too wide from my driving position. I do like having the digital rearview mirror, though, because when you have a big car seat or tall adult in the back seat, the vision back there is hindered.

It’s pretty hard to find a modern car that’s terrible to park, especially in the mid-size SUV segment, and the NX is no different. Even in a small car space, you still have good clearance around you, which hopefully translates to less dings from neighbouring cars!

The 360-degree view camera system is top notch with its quality, and I like that the car disappears and you can see the ground underneath.

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!

The NX is offered with a five-year/unlimited-kilometre warranty, which is on par with its European rivals.

It comes with a five-year capped price servicing program, where services are competitively priced at $595 each.

Servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.

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.
