Lexus RX vs Lexus LX

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.

The Lexus LX500d is a luxury seven-seat 4WD wagon with a big price-tag to match its full-to-bursting standard features list.

The interior is now more cool than cheesy and as a daily driver and long-distance tourer the LX500d offers very impressive levels of comfort and refinement – and it’s no posh pretender off-road either.

Sure, it’s much more of a city conveyance than a country wagon, but the LX500d is spot-on for those who have a premium SUV on their mind.

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.

The LX500d, in keeping with its positioning in the luxury slice of the market, is an imposing, premium-looking vehicle. 

Lexus puts the LX500d’s dimensions at 5100mm long (with a 2850mm wheelbase), 1990mm wide, and 1885mm high (1895mm in the Enhancement Pack-equipped LX500d). This is a big, classy SUV, inside and out, and it’s more than just a 300 Series LandCruiser in a shiny suit.

The optional 22-inch alloy wheels (part of the $5500 Enhancement Pack) add to the overall polished look. 

The interior is a classy mix of woodgrain trim, Hazel leather accents, soft-touch surfaces, Shimamoku ornamentation, plush but supportive seating, and even comfortable arm-rests.

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.

The cabin is a cavernous, plush space and driver and passengers are all generally well served in terms of practicality and comfort.

The tech is simple enough to locate and operate – it was easy enough to get Apple CarPlay working – and the screens are big: the horizontal 12.3-inch multimedia unit upfront, an 8.0-inch screen (to monitor air-con, adaptive air-suspension height, the 4WD system, and other vehicle information), a head-up display, plus a 7.0-inch touchscreen for rear passengers.

Heating and cooling are managed via the climate concierge and everyone can keep themselves as comfortably hot or cold as they like with separate controls.

Storage is only reasonable for such a voluminous interior with a variety of door pockets, cupholders (eight in total), glove box, a deep centre console (with multiple ways to open the lids) as well as map pockets for the second row, cup-holders in the centre fold-down armrest and cupholders for the third row.

The Lexus has a Qi wireless charger and front and rear USB-C charging ports – one up front, two in the second row, and two in the third row. 

There’s a 12V DC socket (front and rear) and a 220V socket in the rear cargo area.

Power-adjustable seats up front mean the driver and front passenger can dial-in their favourite seating position and these seats are very comfortable. Even the second row is plush, but the third row is not quite at that comfort level.

Second-row passengers have air con and entertainment controls, and an HDMI port.

The sunroof – an Enhancement Pack inclusion – is power-adjustable and allows plenty of natural light in through the top.

The Lexus LX500d has a claimed 174L (VDA) of cargo space when seven seats are in use; 982L when five seats are being used (that’s with each half of the power-folding third row stowed flat at the push of a button); and 1871L when all seats are stowed away (the 60:40 folding second-row seats tumble-fold forward), except for the driver and front passenger, of course. 

The tailgate has a foot-swipe-to-open sensor (part of the $5500 Enhancement Pack).

The seven-seat LX500d is the base-spec in the three-variant diesel LX line-up – below the F Sport and Sports Luxury – but you wouldn’t know it from its price-tag.

The LX500d retails for $157,061 (excluding on-road costs), but our test vehicle has an optional Enhancement Pack (which includes 22-inch alloy wheels, sunroof, hands-free power tailgate with kick sensor, $5500) and has been fitted with a towing set-up (towbar etc, $1545 fitted) pushing its price up to $164,106 (excluding on-road costs).

As standard the LX500d features list includes a 12.3-inch multimedia touchscreen (with Apple CarPlay and Android Auto, and Bluetooth), a 25-speaker Mark Levinson sound system, heated and ventilated power-adjustable seats, woodgrain steering wheel trim, 8.0-inch multi-information driver display, four-zone climate control, 7.0-inch touchscreen and separate control panel for rear passengers, multi-terrain monitor with panoramic view, and 20-inch alloy wheels (but, as mentioned, our test vehicle has the Enhancement Pack with 22-inch alloy wheels).

It has a digital rear-view mirror, adaptive variable suspension with low, normal and two high settings, as well as full-time four-wheel drive, a low-range transfer case, locking centre differential, and a variety of driving modes (including off-road modes) and driver assistants.

Exterior paint choices include the no-extra-cost Onyx, or options such as Liquid Metal, White Nova (F Sport models only), Sonic Quartz (not available on F Sport models), Titanium, Graphite Black, and Khaki Metal (on our test vehicle), all of which incur an extra cost.

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.

The Lexus LX500d has a 3.3-litre V6 twin turbo-diesel engine, producing 227kW at 4000rpm and 700Nm between 1600-2600rpm.

It has a 10-speed automatic transmission with manual shift mode, a permanent all-wheel-drive system, low-range transfer case and a lockable centre diff. 

It also has six on-road drive modes – including Eco, Comfort, Normal, Sport S, Sport S+ and Custom – and off-road drive modes.

The V6 is an impressive fit in this behemoth, but even though this is a smooth-shifting SUV, there’s a leisurely, rather than lively, overall feel to how the engine and auto work together.

Because it is so hefty – with a listed 2690kg kerb weight – the Lexus does need a bit of heavy right boot to get going off the mark and during overtaking moves.

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.

The Lexus LX500d seven-seater has a listed fuel consumption of 8.9L/100km on a combined cycle.

Our actual fuel consumption on this test, from pump to pump, was 12.2L/100km. Note: our test included a lot of low-range 4WDing. 

The LX500d has an 80-litre fuel tank – so, going by that on-test fuel consumption figure, you should be able to get a driving range of almost 656km from a full tank.

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.

This Lexus feels tighter and better controlled than previous iterations on sealed surfaces, but it’s still a big rig so it’s no surprise when body roll continually creeps in, with this hefty SUV revealing wallowing tendencies even at optimal ride height. 

The suspension set-up – adjustable dampers, double wishbones at the front, a four-linkage rigid axle at the rear, stabiliser bars front and rear – irons out any major issues, but, even with consistent support from the adaptive variable suspension, it’s not perfect.

Steering is light and precise and adds to this posh 2690kg beast’s overall feeling of low-key composure.

This is a very nice cabin in which to spend time as NVH (noise, vibration and harshness) levels are kept to a minimum.

As mentioned earlier, the drive modes include normal, eco, sport and each adjusts throttle response, engine outputs, and gearshifts to suit the driver and the driving conditions.

Now for a few on-road niggles…

The brake pedals feel too spongy in their action – from stomp to stop – but the ventilated disc brakes front and rear do manage to wrench the Lexus to a controlled halt when needed.

The V6 and auto work well together, and though that transmission remains a smooth shifter, 10 gear ratios still seem like too many to me but, alas, that’s the way of the world.

To the off-road portion of this test…

The LX500d is a great open-road tourer but it does reveal some flaws when it comes to 4WDing – but more about those later.

As well as its robust mechanicals, the Lexus has off-road-capable Cruiser underpinnings with dirt-biased tech thrown into the mix as well. 

There’s plenty of glass around so driver-to-track visibility is fine, steering feels light but takes on a clinical precision during low-speed, low-range 4WDing.

And ‘clinical’ is exactly how the Lexus continues to feel off-road – with multi-terrain select driving modes offering auto, dirt, sand, mud, deep snow, and rock options; with a multi-terrain monitor and panoramic view helping you ‘see’ everywhere on the track; with active height control helping you to lift the vehicle’s body in order to improve off-road angles at the push of a button; and don’t forget about downhill assist control, hill-start assist, crawl control, and off-road traction control.

The danger is that – with so much tech working away at making everything so easy and safe – the driver feels completely removed from the off-road experience. The LX500d isn’t the only culprit, not by a long shot; most of the current crop of off-road vehicles are increasingly offering a sanitised, hyper-controlled version of 4WDing rather than the visceral experience many of us know and love. I’m old and grumpy, sue me.

Our test vehicle has all-season Dunlop Grandtrek 265/50R22 112V tyres, which are fine for sealed surfaces, but they’re not at all suited to the demands of low-range 4WDing in tough conditions, even more so on these 22-inch rims.

Unbraked towing capacity is 750kg, braked towing capacity is 3500kg. The LX500d has a gross vehicle mass (GVM) of 3280kg and a gross combination mass (GCM) of 6780kg.

It has a full-size spare tyre and that’s mounted under the rear cargo area.

The Lexus does not have an ANCAP safety rating as it has not been tested.

Safety features include 10 airbags (driver and front passenger: front, knee, side; rear: side), AEB with pedestrian detection and daytime cyclist detection, front and rear parking sensors, reversing camera with rear camera washer, adaptive cruise control, road sign assist, blind spot monitor with rear cross traffic alert, tyre pressure warning system, and more.

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.

The Lexus LX500d has a five-year/unlimited-kilometre warranty.

Capped-price servicing applies for three years or 60,000km, whichever occurs the soonest. 

Service intervals are scheduled for every six months or 10,000km intervals with each appointment costing $495 a pop over that period.

Lexus Encore benefits – including a loan vehicle during services, service pick-up and return, as well as valet parking offers and fuel discounts – are standard for new Lexus owners.
