Audi Q7 vs Infiniti QX80

What's the difference?

The Q7 was at risk of irrelevancy due to the unfortunate timing of its rivals' life cycles, but Audi made sure that wasn't going to be the case.

As far as mid-life facelifts go, Audi has knocked it out of the park with the Q7, so much so that the case can be made it's now the class leader.

In many ways this Q7 feels like an all-new model, which is quite something. More importantly, the positives well and truly outweigh the negatives.

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.

Good on Audi for throwing the kitchen sink at the second-generation Q7. As far as mid-life facelifts go, this is a really good one.

Up front, the headlights, 'Singleframe' grille and bumper have all been redesigned to ensure the Q7 isn't out of place in Audi's new-generation line-up. Either way, this is a large SUV with presence in spades.

Changes around the side are less drastic, limited to new sills and fresh sets of alloy wheels, including the 20-inch items seen here, which we reckon are pretty unexciting.

The rear end is the best angle thanks to the redesigned tail-lights and rear diffuser, both of which look great. We particularly like the former's segmented design, shared with the headlights.

That said, the real story is happening inside, where Audi has well and truly flipped the script. The old cabin was ageing well in some regards, but not others, and that was reason enough for a complete overhaul.

If the new interior design looks familiar, it's because it is, having been lifted from the much newer – and mechanically related – Q8 large SUV.

Needless to say, it's a technological tour de force, with not one, not two, but three large display screens dominating the cockpit.

Of course, Audi's much-loved version of a 12.3-inch digital instrument cluster is one of them, although it's running new software now.

What is completely new, however, is the pair of stacked central touchscreens, with the top unit measuring 10.1 inches in diameter and the lower item checking in at 8.6 inches apiece.

Both are powered by Audi's latest-generation multimedia system, with the former handling most functions, while the latter is responsible for the climate controls.

Aside from being a fingerprint magnet, this set-up works pretty damn well. Yes, some functions require a few too many taps to get to, but the acoustic and haptic feedback bring some unexpected tactility to what is a largely buttonless system.

Look past the obvious, though, as it's more or less business as usual for the Q7, which is chock full of lovely materials, including the 'Cricket' leather upholstery seen here.

Take for instance the soft-touch plastics used on the upper dashboard and door shoulders. Even the hard plastics found lower down look and feel suspiciously good!

Metallic trims are used throughout to brighten up the interior, while gloss-black finishes are liberally applied to the dashboard and centre console. Frankly, we could do without them as they are fingerprint magnets. Yep, keep a microfibre cloth in the glove box.

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.

Measuring 5063mm long, 1970mm wide and 1741mm tall in facelifted form, the Q7 is large for a large SUV, which goes some way to explaining why it's only available with seven seats.

That said, the third row is more of temporary solution than a permanent one, even for kids.

Granted I'm an adult that's 184cm tall, and therefore not the target audience here, it's still tight back there, albeit up with the best in class.

With the second slid all the way forward, I manage to have my knees pressed up against the seat backrest, while headroom is severely limited.

Footwell space is okay, and so too is toe-room. Again, children will cope, but only on shorter journeys.

Ingress and egress to the third row is made easier by the 40/20/40 split-fold middle bench, which can tumble forward easily with the pull of a tab and then a latch. It's not glamorous, but it's doable.

Conversely, the second row is spacious and easy to get in and out of, even when set up to make the rear occupants as comfortable as possible.

Behind our driving position, around 10cm of legroom is available, depending on the positioning of the bench. No matter what, though, there's plenty of toe-room, and two inches of headroom is on offer, despite the panoramic sunroof.

Indeed, this is one of very few SUVs that can accommodate three adults abreast in relative comfort, even with the transmission tunnel reducing footwell space.

For reference, top-tether and ISOFIX child-seat anchorage points are spread across the second and third rows.

Cargo capacity with the power-folding third row stowed is generous, at 865L, and can be expanded up to 2050L with the middle bench stowed. An undisclosed amount of space is available with all seven seats in use. Either way, it's more than enough for the weekly shop (as you can see in our pics).

The boot is made more useful thanks to the inclusion of four tie-down points and one side storage net, while the lack of a load lip makes dealing with bulkier items a lot easier.

The only real issue we had was where to store the load cover when not in use. There's no false floor to gobble it up, meaning it'll annoyingly live at home when you've got six or more people on board.

That's not to say the Q7 doesn't have other storage options; it's got plenty of them, such as the useful storage nets on the back of the front seat backrests.

The glove box is pleasingly large, although the central storage bin is not, with most of its space taken up by the wireless smartphone charger.

The door bins are simply massive, with the front items capable of accommodating a large bottle and two regular ones, while their rear siblings can take one of each.

Two cupholders are located between the driver and front passenger, while another pair is hidden in the middle row's fold-down armrest. Rear occupants are treated to two smaller items.

Connectivity-wise, in an old-school twist, four USB-A ports are split between the first and second rows. In both instances, a 12-volt power outlet is found nearby.

The former's input options are located in the central storage bin alongside SD and SIM card readers, while the latter's reside at the rear of the centre console, below the central air vents and climate controls.

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 50 TDI is motivated by a 3.0-litre turbo-diesel V6 engine, producing 210kW of power from 3500-4000rpm and 600Nm of torque from 2250-3250rpm.

For reference, the 45 TDI has the same unit but develops 170kW from 3250-4750rpm and 500Nm from 1750-3250rpm.

The former sprints from a standstill to 100km/h in 7.3 seconds, while the latter is 0.8s quicker, putting it in hot-hatch territory.

Either way, an eight-speed torque-converter automatic transmission sends drive to all four wheels via Audi's signature quattro system.

Both variants also feature a 48-volt mild-hybrid system, which consists of a belt alternator starter (BAS) connected to the crankshaft, and a 10Ah lithium-ion battery pack located under the boot floor.

And for those looking to do a little more than usual with the Q7, maximum braked towing capacity is 3500kg.

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 50 TDI's claimed fuel consumption on the combined cycle test (ADR 81/02) is 6.8 litres per 100 kilometres, while carbon dioxide emissions are 180 grams per kilometre.

Audi says the aforementioned 48V mild-hybrid system reduces fuel consumption by 0.7L/100km thanks to its coasting ability, which sees the engine turn off for up to 40 seconds between 55km/h and 160km/h. It also engages idle-stop from 22km/h. In reality, it all works pretty well.

During our week of testing, we averaged 8.9L/100km with limited highway driving, which is a pretty solid result. Naturally, longer journeys will see that figure come closer to the claim, if not exceed it.

It's also worth noting the standard fuel tank takes 75L of diesel, although the optional item accommodates 85L. The 50 TDI also requires AdBlue, with a 24L tank on board.

For reference, the 45 TFSI manages 7.0L/100km and 184g/km.

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 Q7 is a big beast, but it's not as intimidating to drive as you may think.

In fact, it's very easy to live with, if you don't mind managing its size in certain scenarios, such as finding a park in a busy shopping centre.

The SUV's electric power steering is speed-sensitive, which means fewer inputs are required at low speed, making parking and other manoeuvres easier, while stability is improved at high speed.

While not the first word in feel, this system is nicely weighted and surprisingly direct, endearing the Q7 with some sports-car characteristics.

That said, our favourite element is its independent suspension set-up, which consists of multi-link axles with air springs and adaptive dampers.

Needless to say, ride comfort is superb, with the SUV just floating along, even on uneven surfaces.

Introduce a coarse-chip road or a pothole, though, and the Q7 does become unsettled. But this is probably more noticeable because the ride is otherwise so sublime.

Instead, it's through the corners where it's truly exposed, with body control decent but nowhere near class-leading. Yep, it's here that its 2135kg unladen weight (excluding 75kg for driver and luggage) is really felt.

Flick the SUV into its Dynamic drive mode and things noticeably pick up, with extra heft added to the steering and the suspension firming up and hunkering down by up to 40mm. It's an improved experience in the bends, but not a memorable one.

However, our biggest bugbear is the exaggerated turbo lag served up by the 50 TDI's engine. Below 2000rpm, it has absolutely no go. Above it, though, it hammers.

Being a diesel unit, it doesn't have a lot of revolutions to play with, so you find yourself hunting for its upper reaches when accelerating, even around the town.

Making the most of the situation, the 50 TDI's smooth automatic transmission is responsive to kick-downs, but it's not lightning quick, meaning progress is stunted more often than not.

It also doesn't help that the eight-speeder is tuned for economy and therefore likes to keep engine speeds just above idle. This is particularly evident when attempting to power out of a corner.

When playing in the engine's upper reaches, the 50 TDI well and truly comes alive, serving up punchy acceleration, which is easier to access with the aforementioned Dynamic drive mode engaged. It makes shift patterns more aggressive and prompts more consistency.

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.

All Q7 variants come with a three-year/unlimited-kilometre warranty, which is well short of the premium market's new five-year standard.

Audi also bundles in three years of roadside assistance, although this term can be extended up to nine years if the vehicle is serviced at an authorised dealership, which is nice.

Speaking of which, service intervals are every 12 months or 15,000km, whichever comes first. Capped-price servicing plans are available, costing $2310 for three years or $3190 for five.

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).
