Lexus NX450H+ vs Renault Arkana

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 Renault Arkana Esprit Alpine mild-hybrid combines some serious design flair with a reasonable amount of practicality for a smaller family, but it’s hard to ignore the lack of improvement in efficiency following the addition of the mild-hybrid system. That said, it still succeeds on some fronts. It just does it quietly.

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.

I’d describe the Arkana as muscular and sporty, with its strong body lines, twin exhausts and 19-inch alloys. The Satin Grey matt paintwork only enhances this grunty exterior styling.

From the outside, the biggest differences between this and its mid-spec sibling come down to the darker accents across the body and grille, along with the Alpine badging. And while that pronounced rear-end won’t be to everyone’s taste, it certainly gives the Arkana a defined personality on the road.

The Esprit Alpine shines inside the cabin, with synthetic leather and synthetic suede liberally used throughout, while contrasting blue stitching on the seats and blue seatbelts highlight Renault’s Formula 1 ‘Alpine’ racing roots.

There’s some real flair inside that this segment can sometimes lack, and I love how many physical controls there are, from the traditional gear shifter and rotary sunroof dial to the satisfyingly clicky buttons. It’s very ASMR-coded.

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.

The front is roomy enough that you don’t feel penned in, and the seats hug you nicely into place. The armrest sits a little too high for me, but I like that it slides forwards. The heated function is welcome, and the seats remain supportive on a longer trip.

Storage is best up front, with a couple of cupholders, plus decent space and drink bottle holders in each door bin. The glove box is quite deep, although I reckon you’ll pop a rib if you’re on the shorter side trying to access it from the driver’s seat!

In front of the gear-selector is where all of the charging options are and its easy to have them all in one place, with two USB-A ports, a 12-volt socket and a wireless charging pad, although it’s easy for your phone to slide off while you’re driving. For a flagship grade, it's a little disappointing we're not seeing any faster USB-C ports.

At 9.3 inches, the multimedia display isn’t the largest, but it looks more considered than the usual ‘tablet-stuck-on-the-dash’ styling we’re seeing lately. Overall, the touchscreen is responsive and the system is simple to use. The wireless Apple CarPlay also starts up quickly and maintains a reliable connection.

One small gripe is that the volume controls are tucked away on an easy-to-miss stalk that sits behind the steering wheel. I wish they were on the steering wheel itself... because you forget they’re there.

The back seat is a little awkward to access as an adult, with a relatively small door aperture that makes it easy to knock your head on the way in. There’s also not a stack of legroom behind my driving position, and I’m only 168cm. It should suit two kids reasonably well, although my nine-year old notes the armrest sits too high and the seats are quite firm.

Amenities are decent, with two USB-A ports, map pockets and multiple drink holders.

There are two ISOFIX child-seat mounts and three top-tether anchor points, but two seats will fill this space best. You’ll also need to be careful of knocking your head when buckling any tots in.

The boot is the standout, with up to 485L of capacity when all seats are in use and that can jump up to 1268L when the rear row is folded flat.

Its capacity is more than some mid-sized SUVs, and it's handy that you can adjust the floor to two positions. It’s been more than enough for all of my family’s errands this week.

This grade also gets a powered tailgate and a temporary spare tyre.

There are just two variants available for the Renault Arkana, and we’re testing the Esprit Alpine (pronounced AL-peen for any non-Formula 1 fans), which now sports a mild-hybrid powertrain and comes with a relatively modest $990 price increase. That takes this flagship grade to $45,990, before on-road costs.

Our test vehicle is finished in Satin Grey, a matt finish that adds another $1150 to the price tag, but it’s arguably money well spent as it does some serious heavy lifting in the style department.

It’s also priced about on par with its closest hybrid rivals, with the Hyundai Kona Premium starting at $45,950 and the Honda HR-V RS from $44,400, both before on-road costs. Their full-hybrid powertrains are important to consider, though, if you're after outright efficiency.

The Esprit Alpine has the following features:

• LED headlights
• AM/FM/digital radio
• Eight-speaker Bose sound system
• Bluetooth connectivity
• Wireless Apple CarPlay/Android Auto
• Four USB-A ports
• One AUX port
• One 12-volt socket
• Satellite navigation
• 9.3-inch touchscreen multimedia display
• 10.25-inch digital instrument cluster
• Powered tailgate
• Keyless start
• Dusk-sensing headlights
• Rain-sensing windscreen wipers
• Temporary space-saver tyre
• Electric front seats
• Heated front seats
• Heated steering wheel
• Sunroof
• Alpine Blue stitching on seats, gear shift and central armrest
• French ‘tricolore’ blue, white & red stitching on the steering wheel and door trims

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 Esprit Alpine is now a mild-hybrid, combining a 1.3-litre four-cylinder turbo-petrol engine with a 12-volt hybrid system to produce up to 116kW of power and 270Nm of torque. But that’s only 1.0kW and 8.0Nm more than the previous iteration, and it doesn’t improve overall fuel efficiency, so the benefits of the new system are limited on paper.

The idea behind the mild-hybrid system is to improve power delivery off the mark, but a firmer commitment to a proper hybrid powertrain would have done more to improve the Arkana’s efficiency and competitiveness in this increasingly electrified segment.

It’s front-wheel drive and uses a seven-speed dual-clutch automatic transmission, which can seem a little unsure of itself at lower speeds but settles into its rhythm and feels more confident on the open road.

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.

Despite now being a mild-hybrid, its combined fuel consumption remains unchanged at 5.9L/100km. With its 50-litre fuel tank, that gives it a theoretical driving range of up to 847km, which is still a pretty great result for a family SUV.

My real-world result came in at 6.7L/100km after a mix of highway and urban driving, which is a respectable result and not too far off the official figure.

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.

The Arkana can access a decent amount of power once you’re up to speed, but it can feel underwhelming off the mark. It’s also surprisingly easy to lose a little traction when you need to accelerate quickly from a stop.

That said, once you’re up to speed on the open road, it’s more than capable of keeping up with traffic or overtaking when needed.

The suspension is on the firmer side, so you do feel some of the smaller bumps through the cabin, but otherwise I like the handling.

There’s not much body roll through corners and the steering feels responsive, making the Arkana reasonably enjoyable to drive.

The cabin is relatively quiet, although some road noise creeps in on the highway. There are three drive modes that are easy to cycle through, and Sport mode offers slightly sharper gear shifts at lower speeds, which helps give the powertrain a little more urgency.

Visibility is good from my driving position, with a fairly commanding view of the road through the front and sides.

The Arkana isn’t too difficult to park given it’s not a particularly large car, but the 360-degree camera system is underwhelming compared with some of its rivals. My husband reckoned he’d seen better graphics in 8-bit Tetris…

The Arkana’s previous maximum five-star ANCAP safety rating expired in 2025, and it hasn’t been tested since, so it’s currently unrated.

It has six airbags but does miss out on a front-centre airbag, emergency phone call capability, and front cross-traffic alert which we're starting to see become more common in this segment.

Safety equipment includes:

• Intelligent seatbelt reminder
• Two ISOFIX child seat mounts
• Three top-tether anchor points
• Mechanical child locks on rear doors
• Emergency warning lights activated under heavy braking
• Autonomous Emergency Braking (AEB) with pedestrian & cyclist detection
• Driver attention alert
• Forward collision warning
• Rear cross-traffic alert
• Lane keeping aid
• Lane departure warning
• Traffic sign recognition
• Adaptive cruise control with stop/go
• 360-degree camera system
• Front, rear and side parking sensors
• Tyre pressure monitoring
• Hill start assist

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 Arkana is offered with Renault’s five-year, unlimited-kilometre warranty, which is now considered a below-average term for the class, although you do get five years of complimentary roadside assistance.

Servicing intervals are well spaced at every 12 months or 30,000km, which is great if you do heavy kays each year.

Renault also has an assured pricing structure for its scheduled services, with the Arkana averaging around $477 per service across its first five workshop visits, although the fourth is notably more expensive at $859.

Renault currently has 52 locations listed across Australia, although that figure includes some service and parts-only locations, so the network isn’t quite as extensive as some of the mainstream brands.
