Lexus Rx450H+ vs Nissan Ariya

What's the difference?

The new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

I can see how the Nissan Ariya would have changed the game if it launched in Australia back in 2022.

While it is a solid car that’s quiet, comfort-oriented and tech-heavy, there’s now little separating it from the competition apart from the fact it has a Nissan badge and a cracking aftersales package. This is disappointing as we’ve waited a long time for this car to arrive.

Note: CarsGuide attended this event as a guest of the manufacturer, with accomodation meals provided.

The RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

Back when the Ariya was revealed, it started a new design language for Nissan, but five years later almost every model in the Japanese carmaker’s line-up has taken some element of this car’s design.

What this means is while the Ariya was unique, it now doesn’t stand out from the crowd as much as it once did. This doesn’t help given there are now so many competitors out there.

However, in person the exterior of this car is stunning. I’m particularly a fan of the two-tone copper paint available on the Advance+ and Evolve e-4orce.

At the front there is a slim and striking LED lighting set-up that stands out, plus the gloss black faux grille is an interesting take on the brand’s ‘V-Motion’ grille. It has illuminated sections that are only noticeable in dark conditions.

Around the side the Ariya appears to be a lot more coupe-like than you’d expect. There’s a body line that runs from the A-pillar all the way to the tailgate. It gives the car a floating roof effect, which is a current design trend.

Other notable design elements on the side include the charge flap on the passenger side front quarter panel, aero covers for the alloy wheels, and an extensive use of gloss black around the wheel arches and door sills. It’ll be interesting to see how the latter hold up in the long run.

At the back there isn’t a whole heap going on beyond the large rear spoiler, which is intricately designed and there to improve aerodynamics.

There’s also a full-width LED light bar for the tail-lights, which is sandwiched by a Nissan wordmark badge. These lighting set-ups are so common now that they’re a little cliche.

Inside, the Ariya is befitting of its flagship status for the Nissan brand. In the top-spec Evolve trim with the blue Nappa leather upholstery and suede dash highlights. I don’t think it pairs well with every exterior paint colour, but it still looks great.

This also isn’t to belittle the lesser trims. While they have darker interiors, this is likely more preferable for many buyers as they’re less out there. The materials, at least in the Advance+, are still at a high quality.

The steering wheel is leather-wrapped and feels buttery soft in the hand. While I loathe the fact there are gloss-black covers over the physical buttons on the steering wheel, it’s still a step in the right direction.

Ahead of the driver are dual 12.3-inch screens across the line-up. It took me a while to notice there’s a wave between the screens as it’s covered by the steering wheel rim. The touchscreen is incrementally closer so you can reach it more easily.

Another major element of the Ariya’s interior design is the centre console. In the Advance+ and Evolve it has electric sliding adjustment, allowing you to customise the position to your desire.

The use of the faux wood trim looks premium, especially because you don’t expect there to be haptic buttons on it. This helps for a clean, button-less look.

The RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.

Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.

Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.

Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.

Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.

The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.

One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.

Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.

That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.

Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.

My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.

There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.

At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.

Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.

This car is built on a dedicated electric architecture which theoretically gives it many benefits as there’s no space needed for a combustion engine, nor its transmission or driveline components.

While the Ariya benefits from this by pushing the wheels to the extremities, it underwhelms in others. More on this in a bit.

As standard the driver’s seat is mounted very high. I’m 182cm tall and in the seat's lowest position I was only a few centimetres off my hair tickling the roofliner. While this is nice from a forward visibility standpoint, I instinctively want to sit lower in the cabin.

Despite this, the front seats are deliciously comfortable. They offer plenty of electric adjustability, allowing you to find your desired seating position. Depending on the trim they’re heated and ventilated, which is a treat in fickle Melbourne weather.

As noted before, the steering wheel features physical buttons, which is a major plus. They’re clearly labelled and are easy to understand.

Ahead of the driver the digital instrument cluster is classic Nissan. There are a range of informative pages to cycle through, as well as two layouts to choose from. All of them look high-res.

Moving across, the touchscreen multimedia system is also a classic Nissan unit. Almost every Nissan model has a variation of this touchscreen now, which kind of makes the Ariya feel less special.

Thankfully however, the user interface is clear and easy to understand. It’s hard to get lost and even if you do, there are shortcut buttons on the side of the screen.

As standard there’s wireless Apple CarPlay, which is great if you have an iPhone and almost expected nowadays, however Android Auto is only offered in wired form only. This is disappointing from a high-tech flagship.

I appreciate there are haptic buttons for the climate control under the touchscreen. It’s much better than having these functions built into the touchscreen. However, the seat heating/ventilation and the steering wheel heating is in the touchscreen, but you can program it to an automatic mode so it’ll turn on and off with the climate control.

The haptic buttons extend onto the centre console which electrically slides in the Advance+ and Evolve. These ones are for the drive mode and ePedal selection.

Speaking of the centre console, it’s a big bulky unit but it barely offers any storage. Under the centre console lid there’s a wireless charger and a miniscule amount of storage. There’s also a tiny phone-sized slot at the front of the centre console, plus a 12V socket and some USB ports.

It’s disappointing Nissan hasn’t taken better advantage of the flat floor accommodated by the dedicated electric architecture. There’s open space between the driver and passenger, which makes it feel like you’re in dedicated recliners.

As a result of the paltry centre console storage, there are two gloveboxes. One on the passenger side and another in the centre. Both look like they’re sizeable, but that’s just the lid as the actual storage space is a fraction of this.

Moving to the second row I have a decent amount of legroom behind my own driving position. Toe room is negligible however and headroom suffers from the panoramic glass sunroof.

Despite this the second-row bench is still comfortable. It’s laid back, though there’s not much lateral support. This means in the bends you’ll be thrown into the door or into the centre of the car.

There continues to be a flat floor in the second row, plus a minimal hump in the rear bench means you could technically go three-up if you wanted. The limitation at this point is shoulder space.

In terms of amenities there are centre console-mounted air vents, USB-C ports, heated outboard seats (depending on the trim) and a fold-down armrest with cupholders. It’s fairly standard.

From the Advance trim and up there’s a standard hands-free power tailgate. This is handy if you’ve got your hands full.

For the boot space itself, it’s fine but not standout. Two-wheel-drive variants are notably better with 466L of boot space with the rear seats upright. The Evolve e-4orce only has 408L due to the rear electric motor.

As expected there’s no spare tyre at all across the line-up. Instead there’s a tyre repair kit under the boot floor.

No Ariya trim has a front boot.

The Nissan Ariya is launching in Australia with four trim levels – Engage, Advance, Advance+ and Evolve e-4orce.

Pricing starts from $55,840 before on-roads and extends to $71,840 before on-roads. This is more than top-selling rivals like the BYD Sealion 7 and Tesla Model Y. It’s more on par with the likes of the Kia EV5 and Zeekr 7X.

With the Ariya Engage at $55,840 before on-roads, you get 19-inch alloy wheels, LED headlights, dual 12.3-inch screens, wireless Apple CarPlay and wired Android Auto, a wireless phone charger, a six-speaker sound system, dual-zone climate control and charcoal fabric upholstery.

Stepping up to the Advance at $59,840 before on-roads brings a hands-free power tailgate, a 10-speaker Bose sound system, heated front seats and steering wheel, as well as black cloth and synthetic leather upholstery.

The Advance+ at $63,840 before on-roads gains a larger 87kWh battery pack as standard, plus a panoramic glass sunroof, a power sliding centre console, ventilated front seats, heated rear outboard seats, as well as black synthetic leather upholstery with suede inserts.

Lastly, the flagship Evolve e-4orce at $71,840 before on-roads gets an all-wheel drive set-up, 20-inch alloy wheels, adaptive high beams, a digital rear-view mirror, electric steering column adjustment and blue Nappa leather upholstery.

This is a generous spread of variants and while the pricing and equipment list doesn’t stand out from the crowd, none of the trims miss out on the basics.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

There are only two electric powertrain configurations available in Australia.

The Ariya Engage and Advance are powered by a single, front-mounted electric motor that produces 160kW of power and 300Nm of torque. The Advance+ bumps the power figure up to 178kW to compensate for the larger battery pack.

The flagship Evolve e-4orce is the only trim with all-wheel drive. It has a dual-motor set-up with total system outputs of 290kW and 600Nm. This trim is claimed to be able to do the 0-100km/h sprint in 5.6 seconds.

The plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.

The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.

Using our real-world economy figure you can expect a range in excess of 1100km between fills.

The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.

While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.

Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.

There are also two battery pack options in Australia.

The Ariya Engage and Advance come with a 63kWh lithium-ion battery with a WLTP claimed range of 385km. This isn’t much for a car that’s around $60,000.

The Advance+ and Evolve e-4orce, on the other hand, get a larger 87kWh lithium-ion battery. WLTP claimed range is 504km and 487km, respectively, which is much more like it for a vehicle of this size.

All variants have a Type 2 CCS combination charge port on the passenger side front quarter panel with a maximum DC charge rate of 130kW. At this rate this will see the battery charge from 10 to 80 per cent in 35 minutes.

AC charging is offered at rates up to 7.4kW on the Engage, Advance and Advance+ trims. 22kW AC charging is optional on the Advance+ and standard on the Evolve e-4orce.

However, thanks to a launch offer for the first 400 vehicles, all Ariyas are getting standard 22kW AC charging, even the ones that typically don’t get it at all. This is a cool offer and an interesting incentive if you are on the fence on actually buying one.

There’s also a free 22kW AC home charger provided as an additional launch offer. You’ll need to install this unit at your own expense.

For energy consumption it depends on the trim level. It ranges between 18.4 and 20.8kWh/100km. During our testing of the Advance+ we saw an average of 14.2kWh and the Evolve e-4orce we saw an average of 18.0kWh/100km. This would give a theoretical range of 613km and 483km, respectively.

It’s worth noting these average energy consumption figures were according to the trip computer and the driving was on higher speed roads on the outskirts of Melbourne.

The RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

We only got to experience Ariya trim levels with the larger 87kWh battery pack at this launch. It’d be interesting to see how trims with the smaller battery pack fare from a comparative standpoint as they’re lighter but offer less range.

With the Ariya Advance+, it has a single electric motor that offers a decent amount of power and torque. It’s probably all that you’d ever need in everyday traffic.

However, it’s far from being a sporty offering – it’s more comfort-oriented – but when you push it, the limitations of it being front-wheel drive become apparent. Traction control cuts power as soon as the corners get too sharp, but thankfully it never feels like this car is out of line.

For more oomph, this is where the flagship Evolve e-4orce comes in with its dual-motor all-wheel-drive set-up. Although 290kW and 600Nm sounds like a lot, it doesn’t provide neck-snapping acceleration. Instead, acceleration intentionally ramps up incrementally to maintain a serene vibe in the cabin.

This isn’t to call this Ariya trim slow, though. It can do 0-100km/h in 5.6 seconds, which is far from a slouch. The way the power piles on though feels nice during rolling acceleration, making it a lovely tourer. If you do lean into the performance this trim offers however, be prepared to pay for it with a higher energy consumption.

There are multiple regenerative braking modes offered in the Ariya. ‘D’ is normal, ‘B’ exaggerates the effects, then ‘ePedal’ is the closest you get to a one-pedal driving mode. All the modes require you to press the brake pedal to come to a complete stop.

Thankfully, there’s no awkward interaction between the regen brakes and the traditional friction brakes. This helps make it feel like a regular car that just happens to be electric.

The steering changes its weight depending on the drive mode. Regardless of this, however, there is a direct feel through the wheel which is confidence-inspiring, especially out on the open road.

As standard the suspension set-up comprises MacPherson strut front and a multi-link rear across the line-up. With the smaller 18-inch wheels across the majority of the line-up there’s plenty of tyre sidewall to play around with, which makes the ride feel composed and comfortable. It balances the line between being too bouncy and too firm nicely.

The top-spec Evolve e-4orce with its larger 20-inch alloy wheels, however, has less tyre sidewall and as a result the ride is much busier. The effects are made worse when you load more people or weight into the car as it becomes very reactive to every road imperfection, especially large bumps.

Lastly in terms of noise, vibration and harshness levels, it’s extremely quiet in the cabin. This is surprising because the lack of a combustion engine typically makes other noises more apparent.

The Nissan Ariya has a five-star ANCAP safety rating based on testing conducted by Euro NCAP in 2022.

Standard safety equipment includes seven airbags, autonomous emergency braking (AEB), blind-spot monitoring, rear cross-traffic alert, lane-keeping assist, lane centring, adaptive cruise control, driver attention alert, front and rear parking sensors, as well as a reversing camera.

Stepping up to the Advance brings surround-view cameras. This is pretty standard on the safety front.

The AEB system is active from 5km/h and lane-keep assist is active from 60km/h.

The RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.

Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.

This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.

Like other Nissans, the Ariya is covered by a 10-year/300,000km warranty, providing you service at authorised Nissan service centres when required. If you don't, there's only five years of coverage.

The battery pack on the other hand is covered by an eight-year/160,000km warranty.

There’s also up to 10 years of roadside assistance if you service at authorised Nissan service centres.

Logbook servicing is required every 12 months or 20,000km, whichever comes first, and the first five services are capped at $299 each.

Overall this is a fairly compelling aftersales package, plus it helps that Nissan has a substantial dealer network around Australia.
