Lexus LX vs Infiniti QX80

What's the difference?

The Lexus LX500d is a genuine seven-seater with impressive levels of refinement, comfort and even off-road capability.

The interior borders on being chintzy and it’s price-tag is the wrong side of bloody expensive, but there's no denying this Lexus is packed with stuff.

It’s more city than country, more bling than bush tourer – it’s like a tarted-up 300 Series – but that’s absolutely fine for the people who buy these.

I wouldn’t blame anyone for cross-shopping a Toyota LandCruiser 300 Series with this – and then opting for the 300 Series! For one thing, you’ll save a stack of cash.

The petrol-only QX80, really a Y62 Patrol with shedloads of bling, is a curious beast; a big, bold status-boosting premium SUV, which is much better suited to the US and Middle East markets than ours. However, it has a real premium feel, is very smooth to drive and the exterior and interior changes have improved what has so far been a divisive model for a brand with a small but growing fanbase here. Infiniti sold 83 of the previous QX80 in 2017 and is hoping to move 100 of these new ones in 2018; they have their work cut out for them, but if brand confidence is worth a few sales, who knows, they might even top the ton.

In firmly keeping with its target market, the LX500d is a premium-looking SUV.

This is a big unit and everything is slick and in-your-face impressive. Inside and out this Lexus looks a lot like a tarted-up LandCruiser 300 Series that’s been on a recent cycle of steroids. 

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

The interior is a tasteful blend of woodgrain, leather accents, soft-touch surfaces, plush seating, and even comfortable arm-rests.

The bulk of the facelifted QX80’s design changes have been to the exterior and include, most noticeably, new LED headlights with a redesigned, sleeker but more aggressive front end than its predecessor’s softer, more rounded curves.

The new QX80’s bonnet is 20mm higher than before and has been extended 90mm; the side steps have been stretched 20mm wider, and the power tailgate has been re-designed to include sharper, thinner, rear LED taillights and the bumper is visually wider.

The whole body has a higher visual centre of gravity, with this latest raft of design shifts giving the SUV a taller, broader, wider and more angular overall appearance.

The interior includes a bigger, chunkier redesigned centre and rear console and those aforementioned premium touches, such as leather-wrapped heated steering wheel, updated upholstery-stitching, semi-aniline quilted leather patterning on door panels and seats, as well as its stainless-steel sill plates, all add to the premium feel.

The QX80 looks better than it did but, as the previous one was pretty hard on the eyes, the 2018 version may still polarise opinion.

Everyone is well catered for inside this Lexus, in terms of, well, everything.

The tech is easy to use – it was simple 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, air-suspension height, the four-wheel-drive system, and other vehicle information), a head-up display, plus a 7.0-inch touchscreen for rear passengers.

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

Storage is plentiful with the usual array of door pockets, cupholders, big glove box etc, but there’s also a cavernous 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 even cupholders for the third row.

The Lexus has a Qi wireless charger as well as front and rear USB-C charging ports – one upfront, two in the second row, and two in the third row – so that should keep any whinging about devices to a minimum – but, knowing kids, it probably won’t. 

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

Power-adjustable seats upfront make life easy for the driver and front passenger and these pews are as good as what I’d imagine a massage chair is like. Even the second row is on the right side of plush, but the third row is not quite there.

Second-row passengers have their own air con and entertainment controls, and there’s also an HDMI port.

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

In terms of packability, 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 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. 

The boot has a 220V power outlet.

The QX80 is a big unit – 5340mm long (with a 3075mm wheelbase), 2265mm wide and 1945mm high – and, when you’re seated inside it, it feels like Infiniti designers and engineers must have worked hard to maximise the space afforded them for driver and passengers without seeming to have sacrificed any style or comfort.

And that big open space inside the cabin is easy to get comfortable in. There are soft-touch surfaces everywhere – door panels, arm rests, centre-console edging – and the seats are unsurprisingly soft and supportive but tend towards slippery when there are quick changes in speed or direction, or when tackling steep downhills off-road. (It was fun to watch front-seat passengers slip-slide around inside during the 4WD loop)

If you’re up-front you’re well catered for; big glovebox; overhead sunglasses storage; the centre console now has a roomy smartphone storage area; the twin cupholders have been upsized to cop two 1.3-litre cups with handles (up from one 1.3-litre cup and a 950ml container); the USB port has been moved to the other side of the centre console so it’s easier to get to; the storage area under the front passenger arm-rest is now a 5.4-litre compartment, able to hold up to three upright 1.0-litre bottles or tablet devices.

There are nine cupholders and two bottle-holders in total in the QX80.

There’s a sunroof if you get the urge for natural light from above.

Second-row passengers now get 8.0-inch entertainment screens (up from 7.0-inch) and two additional USB ports.

The tip-up second row seats are easy enough to operate and the third row is power 60/40 split-fold-to-flat and reclining.

The QX80 is available with both seven- and eight-seat configurations, with the back seat in a two- or three-seat formation.

There is a 12V outlet in the cargo area.

Pricing has not changed: there is one model and it still costs $110,900 before on-roads and that price does not include paint other than the standard Black Obsidian; metallic paint is $1500 extra. Changes over and above the previous model’s standard features list include 22-inch 18-spoke forged alloy wheels (up from 20-inch), Infiniti’s InTouch 8.0-inch colour touchscreen (up from 7.0-inch), new Espresso Burl coloured trim, new chrome finishes all-round, updated upholstery-stitching everywhere, quilted leather patterning on seats, new headlights, LED foglights and more. There is no Apple CarPlay or Android Auto.

The Lexus LX500d has a 3.3L 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 full-time all-wheel-drive system, low-range transfer case and locking diffs. 

The V6 is impressive and this is a smooth-shifting beast, but there’s a real lazy – not lively – feel to how the engine and auto work.

It’s pretty hefty as well – with a listed 2690kg kerb weight – so the Lexus takes a bit of a wind-up to get going off the mark and during overtaking moves.

The previous generation’s 5.6-litre V8 petrol engine (298kW@5800rpm and 560Nm@4000rpm) remains, as does the seven-speed automatic transmission with adaptive shift control. It also has Infiniti’s all-mode 4WD system, which offers Auto, 4WD High and 4WD Low settings and it has terrain appropriate modes (sand, snow, rocks) able to be dialled in.

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 13.2L/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 about 606km or so. Take off a 30km safe-distance buffer and you have 576km.

The QX80 is claimed to use 14.8L/100km. We reckon that fuel-consumption figure is very optimistic and if QX80 owners are partial to towing boats – as Infiniti reckons they are – or if they tackle some 4WDing, then that figure is going to climb much higher quite swiftly.

The Lexus is a refined and comfortable vehicle on sealed surfaces.

It’s 5100mm long (with a 2850mm wheelbase), 1990mm wide (with a 1675mm wheel track, front and back), 1895mm high, and it has a 2690kg kerb weight.

The woodgrain steering wheel feels nice in the hands but even though the Lexus feels tighter and more controlled than the previous-gen – its body-on-frame structure has shed some kegs – this is a hefty rig so it’s no real surprise that body roll remains pronounced – it always tends to wallow 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 – is aimed at keeping things under control, and it certainly irons out any major issues, but it’s not perfect, even ably supported by adaptive variable suspension.

The brake pedals feel spongy, taking some time to ‘bite’, but the ventilated disc brakes front and rear did pull the Lexus to a controlled stop when I did a “watch out for that roo!” emergency-braking move.

And while, by its very nature, it may not be a very dynamic SUV to drive, its low-key composure makes up for that.

The gutsy V6 and auto work well, if lazily, together, and while that transmission is enough of a smooth shifter, 10 gear ratios seems like overkill to me.

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

It’s quiet inside – very quiet – and there’s no issues with vibration or harshness levels either.

Among its many tech-based attractions, the digital rear-view mirror is a handy touch.

This is a great open-road touring vehicle but with some flaws when it comes to adventuring off-road.

Our test vehicle is shod with Dunlop Grandtrek 265/50R22 112V tyres and these all-season tyres are fine for sealed surfaces, but they’re not up to low-range 4WDing in tough conditions, even more so on these 22-inch rims, as we found out during a few hours at our 4WD testing ground.

The Lexus has Cruiser-like off-road-capable underpinnings with top-layer dirt-focussed tech as well. 

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

And ‘clinical’ is how the Lexus feels off-road – not always in a good way either. Like many contemporary tech-heavy off-roaders nowadays, it’s almost so good that you’re in danger of feeling entirely removed from the actual process of driving.

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 that you usually wouldn’t be able to see 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 the list goes on. 

That’s not forgetting downhill assist control, hill-start assist, crawl control, and off-road traction control.

Don’t get me wrong: high-tech is great because anything that helps maintain safe forward progress out bush or while beach driving is awesome but, Great Odin’s raven, it’d be great if the tech onslaught stops now. As if that’s going to happen.

If you’re looking to tow with your Lexus, listen up: unbraked towing capacity is 750kg, braked towing capacity is 3500kg. It has a gross vehicle mass of 3280kg and a gross combination mass of 6780kg. There you go.

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

In the world of luxury SUVs big is king and this thing is definitely on the chunky side of big, but it doesn’t often feel too cumbersome for its own good, or too bulky to steer in and out of Melbourne’s bustling morning traffic with precision.

During this event, we did a fair chunk of driving – highway, country roads, gravel roads and a decent bit of 4WDing – and, surprise, surprise, it did pretty well, especially when things of this ilk usually exhibit the ride and handling of an old poorly-sprung couch on wheels.

It did, however, feel top-heavy at times and revealed substantial body-roll when pushed around corners at speed or even during some sections of slow, bouncy off-roading, so I’d be reluctant to experience what it would be like without hydraulic body motion control. However, we were willing to forgive it any rocking-and-rolling when that healthy V8 growl kicked in as we gave it the boot.

The 22-inch tyre-and-wheel combination is not the way I’d go if I was going to use the QX80 for any off-road forays but, having said that, we did fine on them, at road tyre pressures, over a decent off-road loop.
It has 246mm of ground clearance and 24.2 (approach), 24.5 (departure) and 23.6 (ramp-over) angles.

The QX80 has coil springs all-round and it was only ever caught out when it thumped through a couple of surprise potholes along a dirt road.

This Infiniti model has a claimed tare mass of 2783kg, but you wouldn’t have known it was that many kegs because it powered up steep and slippery bush tracks, through deep muddy ruts, over greasy rocks and through a few knee-deep mud holes with ease. It was as easy as pulling up, switching your terrain modes and dialling in your setting: 4WD High, 4WD Low or Auto. It has a locking rear diff and very capable hill descent control, which we tested on a few rather steep sections of track.

It’s nice to see vehicle manufacturers unafraid to put their off-roaders, even their pricey luxury ones, through a decent off-road loop at launch because it shows they have confidence in its capabilities.

The QX80 has a maximum braked towing capacity is 3500kg and 750kg (unbraked).

The QX80 does not have an ANCAP safety rating. Safety tech as standard includes blind spot warning, intelligent parking system, forward emergency braking, lane departure prevention (incorporating lane departure warning), distance control assist and predictive forward collision warning, Infiniti/Patrol intelligent rear view mirror (which can display video from a camera mounted in the upper rear windshield) and more. It has two ISOFIX points in the second-row seats.

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

Capped-price servicing applies for three years. Servicing is set at six month/10,000km intervals with each appointment costing $595 over that period.

Lexus Encore Platinum benefits – including valet parking and on-demand vehicle loans – are standard for new Lexus owners.

It has a four year /100,00km warranty. Service intervals are scheduled at 12 months/10,000km. The total cost for three years is $1346.11 (GST included).
