Lexus RX vs Toyota Prado

What's the difference?

So, is the latest Lexus RX good enough to stay, or should it sashay away?

In almost every single way except accessibility (the cheapest is now $15K more expensive, remember), the newcomer is hugely better than the model it replaces, with a level of sophistication and refinement – as well as comfort – that the underwhelming predecessors just could not manage.

And, yes, while there is tech shared with the Toyota Kluger (as there's always been), RX #5 looks, feels and drives much more like a large luxury SUV should.

Speaking of which, few rivals can match the family-friendly RX's combination of customer service, glamour and opulence.

Our verdict then? This Lexus has gone from being a drag to one of the queens of the BMW X5 class. RX... Shantay, you stay!

The Kakadu treatment adds a welcome prestige to the Prado which is already a functional, comfortable daily driver and a very capable 4WD tourer as is.

It's reliably effective off-road and though it lacks the over-the-top macho appeal of something like the 70 Series LandCruiser, it still makes a very appealing platform as a touring vehicle. But this flat-tailgate Kakadu, minus the extra fuel capacity of a Prado with the tailgate-mounted spare, loses tourer appeal due to that fact.

If you choose to opt for a lower-spec Prado you'll forgo some nice Kakadu features – such as KDSS – but it'll still be a Prado after all. Money saved can be spent on aftermarket gear to fit out your new adventure machine.

Or you can wait in line with everyone else for the 2024 Prado...

They used to say that the revolution will not be televised.

At first glance, the same also applies with this fifth-gen RX, since all the big changes are largely out of view.

Precisely how different it looks depends on which angle you're looking at it from.

Observing nose-on, the RX's front tracks and body are wider and it boasts a new Spindle Body grille design which is meant to have a 3D effect, but is quite fussy to some eyes. And this is meant to carry on through to all future Lexuses, by the way.

Yet, in profile, the newcomer is hard to distinguish from the old one, with its returning floating roof C-pillar motif, which looks quite sleek. Yet the wheelbase has been stretched, which results in 60mm more interior space, and that benefits overall proportions as well as occupants.

Some reckon the strip tail-light design and clean surfacing make the rear the RX's most arresting angle.

Note that Lexus has dropped the old RXL seven-seater model – it didn't sell very well. A replacement is coming but it won't be anything like the new RX. Stay tuned to CarsGuide for more on that in the not-too-distant future!

The flat tailgate Kakadu is 4825mm long (4995mm with tyre mounted on the tailgate), 1885mm wide, 1880mm high, and it has a kerb weight of 2290kg (2350kg for the standard Prado).

The 2024 Prado – or the 250 Series as it's known in other markets – has an identical wheelbase to the 300 Series (2850mm), so it's 60mm longer than the current model's. 

That next-generation Prado will reportedly measure 4925mm long, 1980mm wide and 1870mm high, so it's 100mm longer, 95mm wider and 20mm taller than the current Prado.

As mentioned, our test Prado's flat tailgate pack cuts fuel capacity from 150 litres to 87 litres, which results in a substantial drop in driving range. So, it'll factor heavily in the buying decision, especially if the potential owner is keen on off-road touring.

The current Prado's design is less blocky than previous iterations but retains a recognisable Prado chunkiness. If you like your SUVs even more streamlined, but with a healthy dose of retro, you'll have to wait for the 2024 Prado.

At nearly 4.9 metres, the RX is deceptively long, and that pays dividends inside, while a larger and roomier cabin are the main beneficiaries of that stretched wheelbase.

Step inside, and you're greeted by a modern, attractive and functional dashboard that looks and feels upmarket – even in the least expensive version. This isn't always the case with luxury SUVs. You're not aware of corners being cut or cheap materials. It all seems really well crafted.

Sumptuous front seats provide loads of squishy, cushy comfort as well as adjustability to help find the right driving position for you. Taller people can now sit lower down if they like, meaning it's less cramped for them now. In fact, most occupants will find the RX pretty spacious up front.

Lexus has also worked hard to right other previous wrongs as well.

While not especially pretty or distinctive, the instruments are clear and informative, providing a wide array of driving, vehicle and multimedia data as required. That old intimidating tech-overkill presentation has been binned. Mercifully.

For example, the central touchscreen now features shortcuts for the most often-used items, so you're not forever diving into menus and sub-menus for climate control, navigation, audio, vehicle settings or phone access. And there's now a 'Hey, Lexus' voice control function to further aid useability.

Other plus points up front in the latest RX include an excellent audio system, extremely effective yet unobtrusive ventilation, and loads of storage – whether in the decently sized glovebox, beneath the vast centre armrest or within the deep door pockets.

And while they might need a moment to get used to, the e-latch electric door handles soon become second-nature to operate. And they provide a potentially life-saving extra bonus.

Speaking of which, there's even more surprise and delight to help you connect with the RX emotionally. It isn't all about wearing sensible shoes in here.

For instance, the big 14.0-inch touchscreen looks and feels contemporary yet is wonderfully user-friendly. It actually invites you to play around with it. The dashboard's horizontal themes create a sense of width and space that's... freeing. There are far fewer buttons than before, down from 81 to 50, though they're also still around for vital functions like audio volume control. And on some grades, the varying ambient lighting choices include exhilarating, relaxing and arousing.

But while this interior is a huge step forward and one of the most appealing aspects of this latest RX, there are some misfires remaining.

Chief among them is the infuriating cruise control buttons with their new-fangled 'capacitive touch' tech, which is fiddly to use and alarmingly distracting. This is a throwback to the infernal mousepad controller found in older models.

The same applies to the camera-based rear-vision mirror found on higher grades, which can induce nausea at a single glance. Did Lexus actually test this on humans beforehand?

Moving to the rear seat, it's clear the company did put the family first, with that stretched wheelbase and extra legroom it liberates. Your 178cm tester found ample headroom, legroom and kneeroom sat behind a front seat set up for them. Meanwhile, the cushion is well padded and the (reclinable) backrest comfy.

Amenities include face-level air vents, climate controls, USB ports, a centre folding armrest with cupholders and storage, overhead lighting and grab handles, deep door pockets and a decent view out.

Overall, that premium feeling up front continues out back too.

And great news for family car buyers – the latest RX's has a larger boot, it now measures in at 612 litres (and expands to 1678L with the rear seats folded down), and comes with a long, flat floor with some storage underneath.

Note, though, that only the F Sport has a temporary spare wheel – the rest make do with a tyre repair kit.

The Prado's interior has a comforting familiarity about it. Sure, it feels a bit dated, but I like it. It's plush, functional and very comfortable.

The front seats are heated, ventilated and power-adjustable and the driver and front passenger have easy access to the 9.0-inch touchscreen multimedia system, which is simple enough to operate.

There's also the usual complement of cupholders (two in front of the centre console) and USB charge points, as well as the refrigerated cool box that replaces the centre console.

The Kakadu has three-zone climate control so everyone has a hand in how toasty or chilled they are during road trips.

Floor mats in the Kakadu are carpet, not the all-weather rubber mats you get in lower-spec Prados.

The second-row is a 40/20/40 sliding split and the outer seats are heated. Second-row passengers get directional air vents, fan and temp controls, seat-heating controls, 12V point (all in the rear of the centre console), and a fold-down centre armrest with built-in dual cupholder.

The second-row seats have three top-tether points and two ISOFIX locations.

There are mesh map pockets on the driver and front passenger seat-backs.

The third-row seats – in a 50/50 split fold-flat configuration – are button-operated and power-folding. Passengers have a cupholder each, as well as air vents and a speaker mounted nearby. They also have a clear view of the 9.0-inch ceiling-mounted DVD screen.

With the third-row seats in use, boot space is listed as 104 litres.

If not in use, the rear-most seats can be power-folded away at the press of a button and the area used for luggage, concealed by a retractable cargo blind. With the third row stowed away, there's a claimed 553 litres of cargo space.

With the second and third rows folded down and out of the way, there's a claimed 974 litres available.

For reference, the 2024 Prado will have a 12.3-inch multimedia system (including wireless Apple CarPlay), as well as seating for five or seven passengers.

Our test vehicle is the Prado Kakadu, a seven-seat 4WD wagon with a list price of $87,468, excluding on-road costs.

Standard features include a 9.0-inch touchscreen multimedia unit (with Apple CarPlay, Android Auto and sat-nav), three-zone climate control air conditioning, a JBL 14-speaker sound system, a rear-seat entertainment system (Blu-ray DVD player) with 9.0-inch screen and three wireless headsets, button-operated third-row power-folding seats, panoramic-view monitor, tilt-and-slide moonroof, and 19-inch alloy wheels.

It also has a premium woodgrain-look power-adjustable steering wheel with paddle shifters, leather-accented, heated and ventilated front seats, dual-range 4WD, as well as 4WDing-suitable driver-assist systems, such as crawl control and multi-terrain select (both for off-roading), adaptive variable suspension (with three modes: comfort, normal and sport), rear air suspension and Toyota's 'Kinetic Dynamic Suspension System' (KDSS).

Driver-assist tech includes 'Toyota Safety Sense' (including 'Pre-Collision Safety System' with pedestrian detection, 'High Speed Active Cruise Control' and more).

A flat tailgate option (which moves the full-size spare wheel from the rear door to the Prado's underbody) is available for the Kakadu. Our test vehicle has it.

Worth noting that choosing this option reduces your fuel capacity from 150 litres to 87 litres, because you sacrifice the 63-litre sub-tank so the spare tyre can be fitted underneath the vehicle.

Kakadu interior seat trim choices are beige leather accented or black leather accented.

Exterior paint choices include 'Graphite', 'Espresso Brown', 'Glacier White', 'Crystal Pearl', 'Silver Pearl', 'Peacock Black', 'Eclipse Black', 'Ebony', 'Wildfire' and 'Dusty Bronze' (premium paint, on our test vehicle). Premium paint costs $675 extra.

There are accessories aplenty available for the Prado, but there are also bundled packs which incorporate several accessories to suit your lifestyle.

The 'Adventure Pack' includes an alloy bull bar (commercial), light bar (fitting kit sold separately), snorkel, roof rack with alloy roof tray (both sold separately) and weather-shields (left and right sold separately).

Then the 'Weekend Getaways' pack includes a nudge bar (black), light bar (fitting kit sold separately), bonnet protector (tinted), roof racks with bike carrier (both sold separately), tow bar, tow ball and trailer wiring harness.

As per the Toyota RAV4 hybrid, the RX350h uses a 2487cc 2.5-litre four-cylinder petrol engine producing 140kW of power at 5200rpm and 239Nm of torque from 4300-4500rpm.

Combined with a 134kW/270Nm synchronous permanent magnet electric motor and nickel-metal hydride battery, it drives the front wheels via a continuously variable transmission (CVT). Maximum system power is 184kW.

The sprightlier E-Four option adds a second electric motor on the back axle to provide AWD. It betters the 2WD's zero to 100km/h sprint time of 8.1 seconds by 0.2s.

Next up is the RX350, which swaps out the hybrid tech for a 2393cc 2.4-litre turbo unit, pumping out 205kW at 6000rpm and 430Nm from a low 1700-3600rpm, while driving all four wheels via an eight-speed torque-converter auto. Its 0-100km/h time is 7.6s.

Finally, there's the RX500h hybrid, combining the 350's 2.4L turbo (producing 202kW at 6000rpm and 460Nm from 4300-4500rpm) with two electric motors (one on each axle) and a unique six-speed auto, for a combined 273kW. It's rapid too, reaching 100 in just 6.2s.

Oh, by the end of 2023, the RX450h+ plug-in hybrid electric vehicle (PHEV) will also be part of the line-up.

On all models, suspension is the tried-and-tested MacPherson-style struts up front and a multi-link rear arrangement. The RX's platform is new, sharing the TNGA Toyota New Global Architecture with the Camry, RAV4, smaller NX and – you've guessed it – the latest Kluger.

The Kakadu has a 2.8-litre four-cylinder turbo-diesel engine – producing 150kW at 3000-3400rpm and 500Nm at 1600-2800rpm – and that's matched with a six-speed automatic transmission.

This is a solid not dynamic combination, which is fine with me because it yields a drive experience that's equal parts relaxed, assured and undemanding.

Our test Prado has a full-time four-wheel drive system with high- and low-range.

Note: the Prado has a diesel particulate filter (DPF) and issues linked to those systems have been well documented, so head to our Toyota Prado problems page to stay up to date with any DPF details.

The next-generation Prado will feature five powertrains globally, however, Australia will only get a 48-volt mild-hybrid version of the current model's 2.8-litre four-cylinder turbo-diesel engine (150kW and 500Nm), with identical power and torque outputs as the existing engine.

The new hybrid engine will be matched to a new eight-speed torque-converter automatic transmission.

It will have full-time all-wheel drive, a low-range transfer case, a centre diff lock, a electronic locking rear diff and a button-operated swaybar disconnect system – not Toyota's KDSS – aimed at yielding improved wheel travel while off-roading.

No shocks here.

The RX350 turbo slurped 11.0L/100km over our launch drive route, which took in both peak-hour traffic jams and rural highway runs, compared to 9.6L for the 500h hybrid turbo and just 6.4L for the 350h hybrid.

So, how do these compare to the official figures?

Well, quoting the pretty-lax NEDC numbers, the 350 should average 8.7L, the 500h a frankly surprising 6.5L while the 350h shines at just 5.0L in the 2WD and 5.4L for the AWD version.

The corresponding carbon dioxide ratings are 114g/km (RX350h 2WD), 123g/km (350h AWD), 197g/km (350 turbo) and 148g/km (500h).

Technically, then, the most economical RX, the 350h 2WD, can average 1300km per (65L) tank! The 350h AWD can achieve about 1200km, the 500h about 1000km and the 350 turbo just 776km (using a bigger 67.5L tank).

Both RX hybrids can drive silently in electric-only mode stepping off the line, at low speeds or when coasting along, and that's really impressive. Less so is every RX's thirst for more-expensive 95 RON premium unleaded petrol.

The Prado has an offical fuel consumption figure of 7.9L/100km (on a combined cycle).

I recorded 13.4L/100km on this test. I did a lot of high- and low-range 4WDing – but the Prado never seemed to have to work hard.

It has 87L fuel tank capacity – that's 63 litres less than any Prado that does not have the flat tailgate, and going by our on-test fuel-consumption figure you could reasonably expect a full-tank driving range of about 650km.

The Prado with the rear-mounted spare has a 150-litre tank so, based on my fuel figures, you could reasonably expect about 1120km from a full tank.

If you've owned any previous-generation RX, you'll definitely recognise most if not all of their good points, like ease, smooth-road and low-speed refinement, and complete reliability and dependability.

But now the Lexus has gained a far, far broader range of talents and capabilities. And that's a direct result of the series switching to the TNGA platform, like most of its brethren (and Toyota cousins).

Let's begin with the most exciting edition, the flagship RX500h F Sport Performance.

This is the brand's first hybrid turbo, and it's a cracker. Electrified for silky quietness when stepping off the line, the internal combustion engine (ICE) takes over seamlessly as soon as you need to really get moving, providing a rich, torquey shove as required.

While not BMW X5M fast, it's rapid all right, and satisfyingly responsive to your right foot. The whoosh is accompanied by an artificial (albeit quite nice) exhaust note, that's a bit turbine-like, to let you know you are or are about to break the law speeding.

Additionally, wearing 21-inch wheels and tyres, there's an exceptional amount of road grip, for safe, planted handling and roadholding. This applies to all the latest RXs, actually. But – and despite its 100-150kg weight penalty compared to lesser versions ­– the 500h feels the most athletic. Basically, it does what the tin says it should.

The flipside? While the adaptive dampers do smooth out most bumps, it can get a little jittery over some surfaces. And it is prone to some tyre noise intrusion over some bitumen. Yet, compared to former big-wheeled RX, the 500h's ride is comfy enough.

Next up is the RX350. This is basically the 500h with the same four-pot turbo engine but minus the electric motors and battery, so it benefits from a 155kg mass saving. And that's immediately obvious in its better high-speed agility.

However, while the engine loves a rev, the lack of electrification and all that meaty torque it brings is always noticeable, meaning the driver has to always mash the accelerator for overtaking to be over quickly. And as a result, the 350 can sound a bit noisy. Otherwise, for normal commuting and point-to-point travel, this is fine. Unremarkable but supremely capable. You'll miss the hybrid oomph, though. And the economy.

Finally, there's the RX most people buy – the 350h. Yes, there's a RAV4 engine and motor(s) stuffed in haute couture, but this is so much more than that. Performance from a standing start is always brisk, with speed piling on with delightful ease if you so desire, and there always seems to be some muscle left in reserve for instant manoeuvres – whether going fast or slow.

The whole experience is seamless, easy and muted. Only when you floor the throttle does the powertrain whine, but it's not that sort of SUV.

Plus, wearing the 21-inch wheels and with the adaptive dampers, the 350h steers, corners and rides well enough, being both skilful and accomplished, if not especially involving, let alone thrilling.

What we're saying is that the base hybrid proposition is good enough to wear the Lexus badge. The RX has finally come of age, dynamically speaking. And about time.

The Kakadu is an easy-driving and very comfortable 4WD wagon.

It's quiet inside the Prado with most external noise kept to a muffled hum.

Steering has a nice weight to it, although it can feel a bit floaty if you're used to a more tightly controlled vehicle. The driver can dial-in their position as the steering wheel is electric tilt-and-telescopic adjustable.

The Kakadu has a 11.6m turning circle and feels nimble along crowded streets and in busy regional centres.

The 2.8 litre turbo-diesel engine and transmission pairing is an unhurried, almost sluggish combination, yielding a relaxed drive experience, but acceleration is gutsy enough to punch the Prado off the mark and get it moving at pace to overtake when needed.

Brakes – ventilated discs at each corner – were able to bring the 2.3 tonne Prado to a rapid controlled stop every time I stomped them into submission during my patented ‘Watch out for that kangaroo!' emergency-braking tests on dry and wet bitumen.

One of the Kakadu's major points of difference with lower-spec Prados is that it has Toyota's 'Kinetic Dynamic Suspension System' (KDSS), which helps iron out most ride and handling irregularities.

KDSS hydraulically alters tension on the sway bars to suit the terrain; on-road, it tightens them for reduced body roll and more dynamic handling, and off-road it loosens them for greater wheel travel to further improve performance.

The Kakadu also has adaptive variable suspension which can be set to one of three modes ('Comfort', 'Normal' or 'Sport') via an in-cabin switch to help dial-in smooth and well-sorted ride and handling; and its height-adjustable rear air suspension with switchable low, normal or high modes.

The Kakadu's Dunlop Grandtrek AT30 tyres (265/55 R19) are well-suited to on-road driving, but fall a bit short, performance-wise, when 4WDing.

On the loose-gravel dirt track that leads to my unofficial 4WD testing ground, the route had been gouged by deep ruts from recent rains. The Kakadu managed it all well.

And a lot of the credit of that controlled ride and handling is due to KDSS, loosening swaybars to suit the terrain, allowing axles full-stretch articulation as required.

And that's very handy at low speeds when sustaining safe and controlled momentum via maximised traction is the goal.

And this was even more evident when I tackled my favourite set-piece rocky hill-climbs.

The Kakadu trucked over the undulating ground at low revs and with wheels dipping and rising as they stuck to the dirt. Wheel travel in a standard Prado is fine but the KDSS-equipped Kakadu gets even more flex on the move.

It conquered everything with impressive ease, only ever scrambling momentarily for grip because of its tyres.

Swap those with a decent set of all-terrains and you'd instantly make a great off-roader even better.

Steering retains a nice balance at low speeds, throttle response is good (not touchy over bumpy terrain), the driver has plenty of visibility (crucial for low-range highly technical 4WDing that relies so heavily on choosing the correct line) and the Kakadu's dimensions offer off-road angles – of 30.4 degrees (approach), 21.2 (ramp-over) and 23.5 (departure) – that are good for a cityfied SUV wagon.

The Kakadu has plenty of torque across a wide rev range, and front, centre and rear locking differentials.

It also has a raft of driver-assist tech, including crawl control (low-speed low-range cruise control/traction control with five selectable speeds), and 'Multi-Terrain Select' (with off-road driving modes that adjust steering, throttle and traction control to suit the terrain you're on, e.g. rock and dirt, mud and sand etc).

Towing capacity is 750kg (unbraked) and 3000kg (braked).

The Kakadu has a gross vehicle mass (GVM) of 2990kg and a GCM (gross combined mass) of 5990kg.

For reference, towing capacity on the 2024 Prado is tipped to be 3500kg (braked), but, at time of writing, this was unconfirmed.

The Prado has the maximum five-star ANCAP safety rating from 2011, but that rating expired at the end of 2022 and Toyota has no plans to re-test this generation. As mentioned earlier, the new Prado is not expected here until 2024.

The second-row seats have three top-tether points and two ISOFIX locations.

The Prado has seven airbags, three top-tether points and two ISOFIX locations in the second row, and is stacked with driver-assist tech including pre-collision avoidance with AEB, high-speed active cruise control, lane-departure alert with steering assistance, automatic high beam, road sign assist and more.

Lexus now offers a five-year, unlimited kilometre warranty with roadside assistance.

Furthermore, hybrid versions of the RX include a 10-year, unlimited kilometre battery warranty.

Service intervals are at 12 months or 15,000km, whichever comes first.

The RX offers three years and 45,000km of capped-price servicing, with each one costing owners $695 – that's pretty competitive for a luxury brand.

So is the first-rate ownership experience. Amongst other benefits, there's Lexus' 'Encore' aftersales subscription program; free for the first three years, it includes myriad offers and services including discounted petrol.

Plus, owners can have their cars picked up remotely and returned washed, and with free use of a loan vehicle delivered to their door.

The Prado has a five-year/unlimited kilometre warranty, which is the mainstream market standard.

Maintenance is scheduled for every six months or 10,000km, which is more frequent than the more common 12 months/15,000km.

Every new Prado comes with capped price servicing of $260 per service up to the three-year mark, for a total of $1560 over three years.
