What's the difference?
Let's face it. Previous Lexus RXs – and there've been three whole generations since 2003 in Australia and an earlier one (from 1998) if you're reading this from abroad – have always felt a little bit like, well, Toyota Klugers in drag.
Lacking sufficient charisma and talent, none really possessed the appropriate dynamics, sophistication or comfort to effectively take on rivals like the Audi Q7, BMW X5 and Volvo XC90.
At least Lexus had the uniqueness and nerve to release a hybrid version way back in 2006 in the pioneering 400h. Remember that?
Now, there's an all-new RX, and it's had quite the transformation. But is it any good? Let's find out.
Jeep Australia's first plug-in hybrid, the Grand Cherokee 4xe, has arrived at a time when the company’s sales figures need a decent shot in the arm.
Though it’s seemingly spearheading a large and extra-large SUV hybrid push into the Aussie market, with the likes of a Toyota LandCruiser 300 Series hybrid on its way, the marque’s debut PHEV is only available here in the range-topping Summit Reserve spec, and only as a five-seater.
So, does the 4xe have enough of a jump on any large SUV hybrid rivals – including a rumoured but postponed Ford Everest hybrid – and is it enough to give the brand a much-needed boost?
Read on.
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!
A wise man* once said "Being first can sometimes feel like being wrong" and perhaps that's how it is with the 4xe, but at least Jeep Australia is giving the large SUV hybrid realm a good ol' try.
* Former CarsGuide Big Kohuna, Glen Knowles.
The company's first plug-in hybrid, the Grand Cherokee 4xe, is not perfect by anyone's standards, however, it is a definite move in the right direction.
It's a quiet and refined drive, it retains the brand's renowned 4WD capability, and even its hefty price-tag likely won't dissuade Jeep loyalists from giving it a go.
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!
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 Jeep Grand Cherokee Summit Reserve 4xe PHEV retains the regular model’s level of functionality but adds a reasonably classy touch to everything.
All seats offer adequate comfort, support and room.
There are plenty of storage spaces, cupholders etc, and charging points - two USB-A and two USB-C plus a 12V socket in the front and two USB-A and two USB-C plus a 230V point in the back.
Controls are generally easy enough to locate and operate although some buttons are positioned in awkward places – including drive-mode buttons under the steering wheel – and it sometimes takes a few finger-stabs at the multimedia touchscreen to get to where you want to go in the operating system.
In terms of packability, the rear cargo area has a listed 1067 litres of space, and, with the second row folded and out of the way, that space opens up to 2004 litres.
Like everything in life these days, it costs more to get into an RX.
In fact, some $15,000 more, because the old 2.0-litre four-cylinder turbo-petrol RX300 is gone, replaced by the new RX350h hybrid as the new base entry-level model.
But Lexus says there's more than enough extra features to offset the price hikes.
As before, there are three established grade levels available: Luxury, Sport Luxury and F Sport.
Exclusive to the 350h, the base Luxury 2WD kicks off from $87,500 (all prices are before on-road costs). It mates a 2.5-litre four-cylinder petrol engine with an electric motor and battery pack, that drive the front wheels. A second electric motor on the back axle turns it into AWD for $4500 more. That's known as the e-Four system.
The Luxury is far from basic. Standard features include LED headlights, three-zone climate control, electric and heated front seats, keyless entry and start, electric door handles, synthetic leather trim, a 14.0-inch touchscreen with sat-nav, DAB+ digital radio, Android Auto, wireless Apple CarPlay, 12-speaker audio, 'Hey, Lexus' voice control, six USB ports, 40:20:40 split rear seats with auto fold, electrically adjustable steering column, a powered tailgate, roof rails and 19-inch alloy wheels.
There's also plenty of advanced safety kit. Check out the safety section for more details.
Next up is Sports Luxury, available on the 350 (which basically swaps out the hybrid tech for a 2.4L turbo) from $105,900 and 350h hybrid from $111,900.
Keep in mind that, from here on in, every RX comes with AWD.
Sports Luxury equals plush, since it ushers in goodies like bi-LED three-projector headlights with auto high beams and washers, 360-degree surround view monitor, variable suspension damping for a comfier ride, a heated steering wheel, a head-up display, heated/vented front seats, slicker leather, extra fancy front seats, 21-speaker premium audio, wireless smartphone charger, power reclining/folding rear seats with heating/ventilation, rear sunshades, ambient lighting and 21-inch alloys. Active Noise Control is also featured on the RX350.
If you want your RX to be a bit sportier, then there's the F Sport in 350 turbo guise from $99,900; it adds uprated brakes, kick sensors for that powered tailgate and more, but loses the Sport Luxury's power folding/heated/vented rear seat, heated wheel and a few other minor items.
There's also an 500h F Sport Performance. From $126,000, this is the RX range-topper for now. Based on the 350 F Sport, it adds a hybrid setup with two electric motors to the 2.4L turbo – a first for any Lexus or Toyota in Australia, as well as rear-wheel steering and an artificial exhaust note piped through the sound system.
Finally, on the base Luxury, Lexus bundles desirable features like leather, a sunroof, vented front seats with driver's side memory, easy-access entry, a head-up display, fancier digital instrumentation and wireless phone charger in an Enhancement Pack.
Starting from $5100, it's like upgrading from Business to First Class travel. There are other option-pack bundles across the range as well.
So, is the new RX good value for money? Undercutting most rivals while not scrimping on features, it's hard to argue otherwise.
The five-seat Jeep Grand Cherokee Summit Reserve 4xe PHEV has a MSRP of $129,950 (excluding on-road costs).
Standard features include a 10.1-inch multimedia system (with Apple CarPlay and Android Auto), a 10.25-inch digital instrument cluster, 19-speaker audio system, quilted Palermo leather-trimmed seats, air suspension and 21-inch alloy wheels.
It also has a heated steering wheel, 12-way power-adjustable seats and four-way power lumbar adjustment with memory for driver and front passenger, driver and front passenger seat massage function and heated and ventilated seats (driver, front passenger and rear outboard passengers).
A Mode 2 charging cable is also included.
An 'Advanced Technology Group' pack is available as a $5500 option and that includes a head-up display, a 10.25-inch screen for the front passenger, wireless phone charger, and night vision camera.
Exterior paint options include 'Bright White', 'Diamond Black', 'Silver Zynith', 'Velvet Red', 'Baltic Grey', 'Rocky Mountain', 'Midnight Sky' and 'Hydro Blue'.
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 Jeep Grand Cherokee Summit Reserve 4xe PHEV has a 2.0-litre four-cylinder turbo-charged petrol engine, two electric motors (one on each axle) and a 17.3kWh battery.
Combined engine and electric outputs for power and torque are 280kW and 637Nm, respectively. The 4xe has it over any of its stablemates equipped with the 3.6-litre Pentastar V6 petrol engine because that yields 210kW and 344Nm.
The 4xe has an eight-speed automatic torque-converter transmission and regenerative braking.
Drive modes include 'Hybrid' (with combined engine and electric motor providing “maximum instant torque and impressive acceleration”, according to Jeep), 'Electric' (“zero emissions”) and 'eSave' (aims to save battery power).
There are a few options available when it comes time to charge the 4xe.
The 4xe vehicle has a Mode 2 charging cable so you can charge it at home in less than 10 hours, according to Jeep.
With a full charge, the 4xe has a claimed driving range, on electric charge alone, of 52km.
Jeep reckons a Mode 3 (wall box) single-phase electric vehicle charger will fully charge the 4xe in less than three hours.
If out and about and looking for a charge, a 4xe driver can use the onboard 'UConnect' system to locate an appropriate public charging station.
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.
As mentioned, the 4xe has a listed electric-only driving range of 52km.
On our official test day, we drove just under 50km on a full electric charge and then the rest of the trip was courtesy of the good ol’ petrol engine.
Jeep's official figure for the combined cycle is just 3.2L/100km, but that's predicated on keeping the hybrid battery charged at all times. On fuel-only we recorded 11.6L/100km.
The 4xe has a 72-litre fuel tank (you need 95RON premium to fill it), so going by that on-test fuel-consumption figure, you could reasonably expect to get a driving range of about 620km out of a full tank.
Add an approximate electric range of about 50km on a full charge to that figure and you have a total estimated driving range of 670km.
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.
We’re all time-poor, right? So, why should I take up your time and rattle on about the 4xe for a thousand words when I can get the essence of it across to you, the reader, in a few sentences? Call me, Mr Thoughtful.
This is generally a big, quiet and refined, easy-steering large SUV, but it feels bulky at times and tends to be quite fussy on irregular surfaces, exhibiting a jittery ride on even brief sections of light corrugations on dirt tracks.
The 4xe’s PHEV set-up is smooth and highly responsive on-road and you can switch between the aforementioned drive modes to suit the circumstance.
Driving range on electric only is listed as 52km. I only recorded a total distance of just under 50km, and it’s a very quiet and smooth drive while relying on electric power.
It regenerates power rather quickly down big hills and via braking, but we’d exhausted all electric charge by the time we’d reached our 4WD test track.
As expected, this Grand Cherokee tackled every off-road challenge without any strife.
The air suspension, set to full off-road height, is a bonus.
Our 4WD test track consists of difficult set-pieces, including one small steep rocky hill that I’ve seen heavily modified vehicles struggle to conquer and, to the Jeep’s credit, it climbed the incline, no sweat.
The 4xe’s efforts were only ever hampered by its 'all-season' Continental CrossContact tyres (275/45R21) which are much better suited to blacktop driving and the fact the 4xe costs upwards of $129,950 and I didn’t want to risk any damage to it.
The 4xe has a listed wading depth of 610mm but our test track was dry so I never had the chance to do any water crossings.
The Grand Cherokee has a solid enough rep as a towing vehicle but, take note, the 4xe is rated to tow 2722kg.
At the time of publishing, there's wasn't an ANCAP crash-test rating for the latest Lexus RX. But the old one tested back in 2015 managed the full five-star result.
We're expecting a similar outcome, especially due to the RX's stiffer, stronger and lighter body, along with a slew of fresh safety related features.
These include better autonomous emergency braking (AEB) performance, with improved pedestrian and cyclist detection, avoidance braking, lane-keep assist, blind-spot monitoring and adaptive cruise-control capability technologies. The latter now features full-stop/start and low-speed following ability – great for slow traffic jams.
Note there is no data on AEB operating parameters at the time of writing.
Also present are auto high beams, road sign recognition, front/rear cross-traffic alert, reverse parking cameras, all-round parking sensors, tyre pressure monitors and 'Safe Exit Assist' – which won't allow doors to open if passing cyclists or pedestrians are in danger of being struck.
There's also 'Intersection Turn Assist' (providing early brake activation if required), 'Emergency Steering Assist' (extra steering assistance to help keep the vehicle in its lane) and 'Emergency Driving Stop System' as standard across the range – along with a digital rear-view mirror on some grades.
You will also find eight airbags (providing coverage to all outboard occupants, also taking in dual-front occupant knees and a centre item to stop lateral head strikes), as well as Lexus Connected Services with – among other features – an SOS button or automatic emergency services notification with vehicle co-ordinates should the driver be incapacitated following an accident.
Finally, anti-lock brakes with brake-assist and electronic brake-force distribution is also standard, along with stability and traction control systems. Lexus provides three rear-seat child-seat tether anchorages and two ISOFIX latches.
The Jeep Grand Cherokee Summit Reserve 4xe PHEV has the maximum five-star ANCAP safety rating from assessment this year.
Safety gear includes AEB with pedestrian detection, blind-spot monitoring with rear cross-traffic alert, adaptive cruise control, lane-keep assist, driver monitoring, traffic sign recognition, intersection collision assist, and a surround-view parking camera.
The Summit Reserve spec brings with it 'ParkSense' parallel and perpendicular park assist and (low-level autonomous) 'Active Driving Assist'.
It has eight airbags including front, side, and knee (for driver and front passenger), sides (for second-row passengers) and full curtain airbags.
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 Jeep Grand Cherokee Summit Reserve 4xe PHEV has a five-year/100,000km warranty and a lifetime roadside assist service.
Servicing is set at 12-month/12,000km intervals and capped price servicing keeps what you pay for each appointment at $399 for the first five.
