Lexus Rx450H+ vs Nissan Navara

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.

While it won’t appeal on the value front as much as its Mitsubishi Triton engineering twin, the Navara’s tweaks from Premcar make it a more comfortable and livable thing. 

The extra cost is worth it for how much better it is on the road, plus you get more features, regardless.

Whether the changes to the Navara are sexy enough to get people in the dealership door is another question, but anyone who takes this over a Triton won’t be disappointed.

If it's for work, the SL or ST will do. If it's doubling as a family car, the Pro-4X is worth the outlay.

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.

Nissan has done well to inject its own design flavour into the ute, because even though there’s inevitable similarity in the silhouette, it doesn’t just look like a Triton.

Impressive given a lot of the car is the same, and Nissan couldn’t change any of the hard points the Triton comes with. In fact, the Navara’s dimensions are largely the same as the Triton, coming in at 5320mm long, 1930mm wide and 1815mm tall.

The biggest Nissan-specific design element is a nod to the Navara’s heritage, the three little vent lines above the grille hark back to the original D21 generation ute which had these holes in the bonnet.

It’s subjective to some extent, but I reckon the Navara has the Triton beat on the design front.

Depending on the variant, you get some other indicators that this is no Triton, including a sports bar on the rear of the cabin with ‘Navara’ cut into it, or Pro-4X decals if that’s the variant you go for.

Given the lifestyle and off-road focus of the Pro-4X, it also has a bit more trim inside and out to feel more rugged and premium.

The Navara’s new interior is a big step up over the previous generation, even if it is genuinely all-Triton in there. The biggest change is the Nissan badge on the steering wheel.

It’s a ute, so there’s still a lot of plastic, cheap materials and even the nicer looking surfaces are in a few spots made of gloss black plastic (sometimes called piano black) which gets smudged easily and after a short while.

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.

It’s a bit of a shame the Navara doesn’t benefit from the changes Nissan has been making to its interior design and layout recently, because it leaves older Nissans in the dust, in terms of design and ergonomics.

But, the Mitsubishi Triton’s interior isn’t a bad one for the Navara to have inherited, because it just works. It’s uncomplicated and sensible, if a little boring.

There are physical buttons for shortcuts, and the tech is relatively straightforward, even if it does also carry the downside of Android Auto being wired-only. It adds to the somewhat dated feeling the Navara’s interior carries, but the physical space itself is rather sensible.

The Navara’s seats are comfortable, and as the driver it’s easy to find your own preferred position, with the electric adjustment in higher variants being an extra help there.

The driving ergonomics and visibility are also good, which lines up well with the Navara’s driving dynamics and makes it feel less like you’re pedalling a big dual-cab around.

Behind the driver, there’s not heaps in the way of amenity, but the addition of USB ports once you’re past the base SL is welcome for second-row passengers, and the space isn’t cramped by any means.

The Navara has a tub capable of easily fitting a Euro pallet, according to Nissan’s specs, but with its distance of 1135mm between wheel arches, it won’t fit an Aussie pallet. The tub is almost square, at 1555mm long and 1545mm wide, and 525mm tall. 

Plus there’s the 3500kg towing capacity and its payload ranging between 964kg for the Pro-4X or up to 1064kg in the base SL.

The new D27 generation Navara starts from $53,348, before on-road costs, so it’s already more expensive than the Triton it’s based on, but we’ll get into the main, somewhat oily reasons for that in a bit. 

The Navara’s available in four variants at launch, SL, ST, ST-X and Pro-4X. They’re all 4X4 dual-cabs, so it’s mainly the features for each trim level that make the difference when it comes to pricing.

The SL starts off with a lot of the basics covered. There are LED headlights and tail-lights, climate control, the same 8.0-inch multimedia touchscreen as the rest of the range and digital radio as well as Android Auto and Apple CarPlay.

Its aforementioned touchscreen is also a little larger than the one in the Triton it’s based on. Then there’s the 7.0-inch driver display screen which lives between the two physical dials.

At this point in the range the steering wheel is polyurethane and the floors aren’t carpeted, just covered with vinyl. It’s a work ute and it feels like one.

Things pick up slightly with the ST, which starts from $56,765, and gains alloy wheels, auto-folding mirrors, a leather-accented steering wheel and floor carpet, plus now side-steps and a sports bar. It also adds USB ports in the second row for charging, so it’s probably the minimum grade you’d want if you’re ever going to have kids in the back. Essentially, it gains a few things that make it feel a little more livable without getting too fancy.

The ST-X is a fair step up in price, it’s $63,177, but gets better suspension, 18-inch alloys, leather-accented and heated front seats and a power adjustable driver's seat, dual-zone climate and a wireless phone charger.

It also gains a centre limited-slip differential, drive modes more compatible with off-roading, different styling elements and push-button start, so you don’t need to use the physical key.

The top-of-the-range (until the Warrior arrives) is the $68,418 Pro-4X with more design changes, all-terrain tyres, a black sports bar and roof rails, contrast stitching and specific seats with Pro-4X styling. It’s the variant Nissan Australia expects to be the most popular, too. It also has the same diff and better suspension the ST-X gains.

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.

A 150kW/470Nm four-cylinder turbo-diesel engine lies under the bonnet, which falls a little short of some rivals, but isn’t glaringly weak.

Its power lines up with, for example, the Toyota HiLux, but torque falls short of its rival’s 500Nm. It’s the same story for the Ranger, though that ute slips a nose ahead with 4.0kW more than HiLux and Navara in its four-cylinder guise.

The Navara’s six-speed automatic transmission also sends that power and torque to all four wheels, though how exactly it gets there depends on the spec and whether you have a centre differential or not.

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.

From the Navara’s 75L tank, a claimed 7.7L/100km is used on the combined (urban/extra-urban) cycle, though on the launch drive we saw the trip computer hovering around 9.0L/100km.

With a few hundred kilos in the tray, that jumped up to the low 11s.

Hypothetically, if you manage to get close to Nissan’s claimed consumption, you should be able to get more than 900km out of a single tank of diesel. Nissan’s claim isn’t too outrageous, either, considering the type of driving a car launch generally consists of isn’t normally conducive to favourable fuel consumption figures.

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.

Now we get to the biggest reason you’d consider a Navara over the Triton it’s based on.

While the Navara benefits from having a relatively new platform underneath it - thanks Mitsubishi - it’s still a ladder-frame dual-cab ute so expectations weren’t exactly on the floor, but they also weren’t sky-high.

And sure, a lot of the details about the new Navara aren’t groundbreaking, nor is much of the way it drives - but the changes Premcar has made to the suspension in this ute are well worth the extra outlay.

What Premcar has done with the Navara, on what we would guess is a relatively constrained budget, is find the most cost-effective way to make the ute better to drive.

They went with upgraded dampers which have been tuned to balance control and comfort with the ute’s off-road ability.

The result? A very controlled front-end, more communicative steering and confidence on the road to drive over even rough surfaces without fear of being flung off the road. Ladder-frame utes don't normally feel so controlled over rough surfaces at high speeds.

It’s worth noting that while the SL and ST still benefit from the suspension upgrades, the ST-X and Pro-4X in particular are much better to drive than you’d expect from a dual-cab ute.

Some of the roads around Canberra are particularly rough, even close to town where the speeds are lower, but the Navara handled myriad surfaces and conditions on- and off-road, in the soaking wet and when it was bone-dry.

Aside from one particular section of the launch that may have just been a little unkind to the ‘stiffer’ sidewalls on the ST-X compared to the Pro-4X, the Navara’s behaviour was not only confidence-building, but allowed for a degree of fun not normally present in the class.

The steering feel left no guesswork necessary, and there’s not a huge on-centre dead-spot as is often the case in a dual-cab. Nice and direct without being too heavy.

The Navara’s weak point, which still gets a pass mark, is probably that its drivetrain now feels older than the ute in which it lives. The outputs are passable, and the transmission finds the correct place well enough, but in a world of 10-speed autos in Rangers or petrol plug-in hybrids, a bog-standard turbo-diesel with six gears has to be bang-on perfect to keep up. 

The Navara’s is adequate, but once you’re used to it, the drive experience is a step above most in the ute segment in terms of control, something that’s hard to come by in this segment.

It translates well to off-roading, where the ute’s front-end settles very quickly over ridges and undulating surfaces without the harshness of a too-stiff set of dampers.

Unsealed roads feel easily dispatched even at relatively high speeds, and with the right tyres (a la Pro-4X) the Navara is a seriously capable thing.

If you find yourself the owner of a D27 Navara and never leave the bitumen, you’re missing out.

The new Navara inherits the Triton’s maximum five-star ANCAP rating from testing in 2024. It scored notably well in Child Occupant protection, though its score for Safety Assist isn’t as high as some rivals.

Eight airbags mean the Navara’s got occupants cushioned in case of the worst, while the whole range has the same suite of safety tech, including a surround-view camera, forward collision warning and AEB, front- and rear-cross traffic alert, driver monitoring and traffic sign recognition, front and rear parking sensors and trailer sway control.

The Navara’s driver monitoring, however, suffers the same overzealousness as the Triton. Nissan didn’t reprogram any of the ADAS systems which means the car will regularly accuse you of being distracted if you’re not looking directly at the road ahead. Checking mirrors or a map in the centre screen will trigger this.

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.

Nissan’s 10-year/300,000km warranty is fantastic but applies only if you service with Nissan. It’s five years with no kilometre limit otherwise. 

There’s five years' of flat-price servicing at $499 per visit, every 12-months or 15,000km, whichever comes first.

Roadside assist is also free for a decade if you service with Nissan, or a year otherwise.

Given there are around 180 Nissan dealers nationwide, finding one shouldn’t be a challenge.
