Infiniti QX80 vs Lexus GX

What's the difference?

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.

Talk about nailing the brief. If you can live with the fuel bill, the Lexus GX won’t just drag you up from a Prado, but sideways from an LC300. I still think the Overtrail looks the best, but if yours is a city life, you can’t go past the entry-level model for its value proposition.

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.

I reckon Lexus has nailed the brief with this GX, especially in the deep 'Graphite Black' which makes it look even tougher.

It’s worth pointing out there are two distinct looks on offer with this Lexus, the Overtrail fitted with smaller wheels, off-road rubber, more aggressive arches and unique bumpers.

The Luxury and Sports Luxury are more street style, and I think the GX Overtrail looks ace. There’s no over-the-top grilles or design flourishes, just a big, blocky SUV that looks plenty tough.

Inside, it’s a high-tech and premium feeling space. The seats are lovely, the tech is big clear and easy to use, the cursed Lexus 'Remote Touch' track pad has been consigned to the history books in favour of a touchscreen and the lovely cabin materials extend to the back tows, too.

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.

The GX is a big truck, though admittedly not Lexus’ biggest , stretching just over 5.0m in length, a little more than 2.1m in width, around 1.9m in height and riding on a 2.85m wheelbase.

Only the Overtrail is a five-seater, with the more road-focused trims providing seating for seven. It also means the Overtrail gets more boot space, while the seven-seaters gets 291 litres of room behind the third row, growing to 1138 litres and 2177 litres when you start lowering the seats.

All models weigh in excess of 2.5 tonnes, by the way, and will tow a 3.5-tonne braked trailer. And for reasons known only to Lexus, there are 12 cupholders included, which means each passenger can bring 1.7 drinks.

The big question with seven-seaters is how much room you have in the back, and the GX is pretty generous. I enjoy plenty of room for my 175cm frame behind the driver’s seat, and climbing into the back is relatively easy, too.

The middle-row seats collapse and fold right away, meaning you can climb into the third row without too much grunting. And once there, you’ll find room for adults along with two of the five USB connection points dotted around the cabin.

Believe it or not, the shiny beast you see in this review is the entry-level Lexus GX, the 550 Luxury, which lists at $116,000, before on-road costs.

Now be warned, according to Toyota’s website, that translates into more like $128,000, drive-away (in NSW). It’s also a long way above the entry-level Toyota Prado, the GX, which lists at $72,500.

But something, something, something ‘premium’, I guess. And besides, you do get a whole lot of stuff — and a whole lot of engine — for your money. 

The entry-level GX nabs 20-inch alloys with a full-size spare, LED lighting all around (including DRLs and fog lights), front and rear scuff plates, roof rails and a powered tailgate hinged at the top, rather than the side.

Inside, there’s seating for seven, wrapped in synthetic leather, heated and ventilated front seats, and heated window seats in the second row. There's also three-zone climate, a 14-inch central screen with wireless Apple CarPlay and Android Auto, a 10-speaker stereo, a 12-3-inch driver screen, a head-up display and wireless device charging.

The Sports Luxury is the most expensive GX at $128,200, before on-roads, and it gets 22-inch wheels, adaptive suspension, better lighting and a fixed glass roof with a sun shade. Inside, there’s a 21-speaker Mark Levinson stereo, leather seats with a massage function for the front row and a digital rear-view mirror amongst other added goodies. 

Then smack-bang in the middle of the GX range is the Overtrail, which lists at $122,250, and is designed to be the most off-road-focused model of the lot.

It rides on 18-inch alloys, gets special 4WD-focused bumpers and provisional mounts should you want to install rock rails. There’s also an electronic rear diff lock and what Lexus calls its 'Kinetic Dynamic Suspension System', which automatically disconnects the front and rear sway bars for serious wheel articulation when off-roading.

Inside, it’s a five-seat-only deal, with a synthetic suede seat material and unique design treatment.

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.

This is a pretty straightforward choice, as you get to choose from exactly one engine option. Every GX scores a very punchy 3.5-litre, twin-turbo V6 engine, along with a 10-speed automatic that feeds the power to all four wheels.

The engine produces 260kW and 650Nm and it feels sprightly.

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.

It is thirsty, the GX. It has a big 80-litre fuel tank and the official fuel consumption figure for the combined (urban/extra-urban) cycle is 12.3L/100km.

That translates to a theoretical range of 650km. But I don’t love your chances. We were using more like 20 litres per hundred kays (though that was in the city) which drops the range figure to more like 400km.

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).

Piloting a big 4WD with genuine off-road aspirations in the city is always a lucky dip, but the Lexus GX falls on the more car-like side of that equation.

Sure, it never feels quite as tight as a true road-focused SUV, but nor does it feel overly floaty and hard to manoeuvre. In fact, should you never venture off the tarmac — which I suspect is a category many of its owners will fall into — you can pretty easily forget you’re driving a Prado-based 4WD.

The steering feels a little vague, and the manoeuvrability isn’t terrific, but the tech on board makes navigating tight spaces pretty breezy, and I found it easy enough to drive and park in town.

That engine, by the way, is a gem. Sure, you can feel your child’s trust fund evaporating every time you flatten the accelerator, but the GX doesn’t want for grunt, and you’ll have no problem getting going and up to speed.

The transmission is seamless in the way it goes about its business, and while not particularly quiet, the drivetrain feels like it perfectly suits the nature, and size, of the GX.

In short, it's an off-roader that won't sap your will to live should you never venture off the tarmac, and it looks damn good doing it, too.

The GX features a long safety list (think AEB, lane keeping assist, rear cross-traffic alert, etc), and while not yet ANCAP tested, I’d be surprised if it didn’t nab a strong rating.

But I want to call out one feature you’ll love, especially if you’re nervous about driving a bigger vehicle.

It’s technically an off-road camera, which fills the 14.0-inch central screen with exactly what's happening beneath the tyres, but it also comes in plenty handy when parking.

Basically, the GX disappears from the 360-degree bird's-eye view, meaning you can see exactly where the parking lines or lane markings are.

The airbag count runs to nine, including full-length side curtains and there are three top tethers and two ISOFIX anchors across the second row for securing child seats and/or baby capsules.

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). 

The GX is covered by Lexus' five-year/unlimited kilometre warranty, which is good. And there’s five years capped-price servicing, which is also good.

But less good is the fact service intervals are every six months, which is annoying, and they cost $595 a pop, which means you’re looking at almost $1200 a year to keep this on the road - or almost six grand over the first five years.
