Infiniti QX80 vs Audi SQ8

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.

The Audi SQ8 isn’t your typical performance SUV. It’s more refined and less flashy. The tech can be more complicated than it needs to be and if you’re wanting that V8 soundscape, you won’t find it here.

However, the handling and on road experience are superb plus you can comfortably haul the family around and look good doing it.

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.

The SQ8 is a gorgeous coupe-style SUV that looks purposeful and poised with its balanced proportions and wide stance. It’s stands apart from its siblings thanks to the S-styled nose treatment and our test model's black accent package makes the honeycomb grille look even sportier. 

The update sees new air intake vents at the front, matrix LED headlights and new chrome exhaust tailpipes.

The upgraded 23-inch alloys with red calipers behind them hint at what’s under the bonnet, as does the Sakhir (sack-heer) Gold paintwork which is aptly named after the one-off Grand Prix race circuit.

The interior looks luxuriously appointed with the black Valcona leather upholstery and the dash is headlined by three high-end technology screens. The SQ8 also gets sport seats featuring a quilted design and 'S' badging but there’s not much else separating it from its siblings.

Audi fans will love the the SQ8's more understated interior but newcomers might be surprised it's not as flashy as some of its rivals.

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 upper large SUV tag certainly makes sense when it comes to cabin space because there's a lot of it. Both rows enjoy ample head- and legroom and access is great thanks to wide door apertures and high ground clearance.

Comfort is high with well-padded seats and thanks to the Sensory Package all but the middle back seater get some luxury extras.

The centre rear position has compromised legroom courtesy of the transmission tunnel, so it's best for a kid. However, the front seats take the cake with their massage, heat and cooling functions and adjustable supports.

Amenities are great throughout the car and the extendable sun visors, rear electric sunshades, soft-close doors and four-zone climate control clinch the practicality deal.

Individual storage is a bit sparse up front with two cupholders, a drink bottle holder in each door and a shallow middle console that realistically only fits a phone.

The glove box is a great size. I can fit my handbag in it, but there are not a lot of areas to pop your smaller items in.

Individual storage is a bit better in the rear as you get two big map pockets, a drink bottle holder in each door, plus two cupholders in the fold-down armrest - so it feels like you have more places for your bits and pieces.

Technology looks amazing but overwhelming to use until you wrap your head around it all. The haptic feedback also gets tired fast. The built-in satellite navigation is super simple while the head-up display and digital instrument cluster feature pull through directions, which is handy.

Charging options are good with each row getting two USB-C ports and a 12-volt socket but the front also enjoys a wireless charging pad. The pad is slow to charge, though, and left my iPhone feeling super hot whenever it was used.

The boot is a good size at 605L and easy to access, too. The sloping roof means larger items have to sit flush with the seats but you shouldn’t have to worry for road trips. 

The back seat has a 40/20/40 split which opens up storage options and this model has a powered tailgate.

There are three fuel-based variants for the Q8 and the model on test is the top-spec SQ8 TFSI quattro. Its mid-life refresh has seen a price hike of $10,015, bringing it's before on-road costs price to $178,815.

Our test vehicle has also been fitted with a few extras, like a 'Sensory Package' ($14,400) which includes a black headliner, upgraded 23-speaker Bang & Olufsen 3D surround sound system, massage function for the front seats, heat function for the rear outboard seats, electric sunshades for the rear row and an air-quality perfume function.

Also fitted are various black and matt carbon accents across/inside the body for a total of $5400, optioned 23-inch alloy wheels ($3000) and specialised 'Sakhir Gold Metallic' paintwork for $1600. Which brings the total MSRP price tag to $203,215.

Even with all of these extras, the SQ8 is still the most affordable performance SUV compared to its nearest rivals as the Porsche Cayenne GTS starts from $212,600 MSRP and the Mercedes-AMG GLE 63 outstrips them both at $272,300 MSRP.

As you'd expect the standard features list is robust for the SQ8 and includes premium features like a panoramic sunroof, electric front seats with heating/cooling and memory functions, full-leather upholstery, soft-close doors and a heated steering wheel.

There is a bunch of high-end technology throughout which includes a colour head-up display, 10.1-inch touchscreen multimedia system, 8.6-inch climate control panel, 12.3-inch digital instrument cluster, satellite navigation, wired/wireless Apple CarPlay and Android Auto, digital radio, four USB-C ports, three 12-volt sockets and a wireless charging pad.

Practical features include keyless entry and start, rain-sensing windscreen wipers, dusk-sensing LED headlights, a powered tailgate, adaptive air-suspension and four-zone climate control.

Overall, not a bad list of features for this part of the market and you won't be left wanting.

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.

Our test vehicle has a 4.0-litre, twin-turbo petrol V8 engine that produces 373kW and 770Nm. That means it sits in the middle of its rivals in terms of outputs with the Mercedes being top-dog with its 450kW/850Nm combo.

Still... the SQ8 is no dainty flower when it comes to power delivery and has an impressive 0-100km/h sprint time of just 4.1 seconds. 

The SQ8 is a full-time all-wheel drive with an eight-speed auto transmission and the whole engine combo delivers a powerful but elegant on-road experience.

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 official combined (urban/extra-urban) fuel cycle figure is 11.9L/100km, which is lower than its rivals.

My real world usage sits at 12.3L/100km after a mix of open-road and urban driving.

This result is decent for a performance SUV but expect it to be thirsty in an urban environment as the on-board gauge hit the mid-20s in the city.

Based on the large 85L fuel tank theoretical driving range is 714km and around 690 using our real-world result. Respectable for a performance SUV but not as good as some family SUVs.

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 SQ8 delivers on power because it’s effortless to get up to speed and the pick up is super responsive when the start/stop function is turned off (otherwise there can be some lag).

The engine doesn’t sound like a big and grumbly V8, though. There are some growls but it’s mainly when you turn the engine on and not to be obnoxious about it but if you're in a V8, you want to hear it as it’s part of the fun of having a big bruiser engine like this!

What doesn’t help the V8 soundscape is the fact the cabin sounds like a noise-cancelling headphone inside. There is a small hum from road noise but it’s pretty darn quiet. Almost EV quiet at times but that means the driving experience leans more towards refined and elegant rather than sporty and fun. 

The SQ8's handling is great - super direct steering, stable in corners and well-rounded passenger comfort when it comes to suspension.

You still get road feedback, which I like as a driver, but it’s not too stiff thanks to the adaptive suspension.

The SQ8 is a large car but you wouldn’t know it when it comes to parking. The 360-degree view camera is clear and the dynamic guidelines help you to position this big unit even the smallest of car parks.

The SQ8 has a maximum five-star ANCAP safety rating from testing done in 2019 and features eight airbags, including side chest airbags for both rows. It's common to only find the latter in the front – so that’s great for a family car.

The SQ8 scored well across its ANCAP individual protection segments, scoring 93 per cent for adult occupant, 88 per cent for child occupant, 71 per cent for vulnerable road user and 75 per cent for its safety assist.

The SQ8 has a long list of safety features including blind-spot monitoring, safe exit warning, driver attention monitor, fatigue reminder, matrix LED lights, SOS call, forward collision warning, rear collision warning, rear cross-traffic alert, lane keeping/departure aids, tyre pressure monitoring, adaptive cruise control (with stop & go and lane keeping), park assist and a 360-degree reversing camera plus front and rear parking sensors.

The rear row features two ISOFIX child seat mounts and three top tether anchors.

The SQ8 has AEB with car, pedestrian, and cyclist detection and is operational from 10 – 250km/h but it is usual to see this system operate from as low as 4.0km/h.

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 SQ8 comes with a five-year/unlimited km warranty, which is a normal term for the class.

It also comes with capped servicing for five years or up to 75,000km and averages $920 per service, which is very good for the segment.

Servicing intervals are reasonable at every 12-months or 15,000km, whichever occurs first.
