Infiniti QX80 vs Mercedes-Benz GLC-Class

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 new Mercedes-Benz GLC200 might be the base-grade, but it doesn’t look or feel like it. From the outside, it’s stylish and refined, and inside, it delivers that signature Benz luxury with premium features, impressive tech and a beautiful cabin.

While the engine isn’t wildly powerful, it’s more than capable for everyday driving and long stretches on the highway and the ride quality overall is smooth, quiet and composed. It loses points for being more expensive than its entry-grade rivals and for those steep ongoing servicing costs, which could be a sticking point for some buyers.

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 GLC is a handsome SUV with a strong, confident stance. It looks fit and premium, but not overly sporty, especially with the standard 'Avantgarde' exterior styling seen on our test car.

The entry-level grade rolls on 19-inch alloy wheels, features slimline running boards, LED lighting all around and an interior ambient lighting package that even includes logo 'puddle light' projection from the side mirrors.

Inside, the GLC200 doesn’t skimp on style. You get sports seats trimmed in synthetic leather (available in a range of colours), plus a panoramic sunroof, flashy dual displays and a black headliner that adds a cocooned feel.

The ambient lighting is a real standout and reminiscent of sci-fi films like Tron! It adds to the cabin’s upmarket vibe.

Combined with the soft-touch surfaces and neat trim details, the interior feels luxurious. And to be frank, it should at this level. But not every base-grade SUV in this segment gets it right. This one does.

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 cabin is spacious in both rows, with decent access thanks to wide door apertures and 195mm of ground clearance. That said, it’s the kind of cockpit you sort of tuck into and I knocked a knee or elbow on the steering wheel getting in (my husband joked this was just a user issue). My eight-year old had no trouble hopping in and out, though.

The front seats are best described as sumptuous, with features like expandable under-thigh and lumbar support. It’s super easy to get comfortable and stay that way, a big plus for anyone who does long drives, like I do.

The rear seats are equally comfy, with generous padding and deep bases. You’ll find three top-tether points in the back row, but realistically, it’s a space better suited to two child seats.

Keeping the cabin tidy is simple thanks to thoughtful storage throughout. There are deep door bins with drink bottle holders, a couple of cupholders in each row, a largish glove box and a dual-lid centre console.

Up front, there’s also a phone cubby, two USB-C ports and a wireless charging pad. In the rear, you get another two USB-C ports and some handy map pockets.

The boot has proven to be a practical space, with 620L of capacity and a level load floor. There’s a reversible mat and underfloor storage, which is also where you’ll find the space-saver spare tyre.

This grade now includes a powered tailgate, a welcome addition, and the second row folds electrically in a 40/20/40 split, giving you more flexibility when you need it.

The updated media display is easy enough to use once you spend a bit of time with it. The touchscreen is responsive, and wireless Apple CarPlay maintained a steady connection throughout our test. I also appreciated how the instrument cluster and head-up display pull through directions from either your phone or the in-built sat nav system.

There are five variants in the GLC range, and for this review we’re testing the new entry-level GLC200, priced from $84,455, before on-road costs.

While it’s definitely more affordable than the next step up, the GLC300, it still wears the highest price tag among its base-grade rivals, with the Audi Q5 35 TDI starting from $73,400 and the BMW X3 xDrive20i from $77,601.

That said, the GLC200’s generous equipment list could easily convince you it sits higher in the range. Standard features include 19-inch alloy wheels, synthetic leather trim as well as electric front seats with memory, heating and Mercedes’ ‘kinetic’ function.

You also get a panoramic sunroof, a slick 12.3-inch digital instrument cluster, a colour head-up display and a vertical 11.9-inch media screen running an upgraded operating system with satellite navigation plus wireless Apple CarPlay and Android Auto.

Practicality hasn't been overlooked, either. There’s a space-saver spare tyre (a welcome change from the run-flat tyre solution often employed by Euro brands), a handsfree powered tailgate, adaptive LED headlights, dual-zone climate control, four USB-C ports, two 12-volt sockets and a wireless charging pad.

Our test car also includes the optional 'Plus Package', which adds $5846 to the price. It bundles in a 15-speaker Burmester sound system, digital matrix LED headlights, heated and noise-insulating glass, augmented reality navigation and a digital key via the Mercedes-Benz app.

You’ll also find a few extra safety additions here, such as a lane centering aid, emergency steering assist, interior monitoring and external surveillance for added occupant protection and theft deterrence.

Overall, a bit more expensive but you get an impressive amount of features.

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 GLC200 is powered by a 2.0-litre, four-cylinder, turbo-petrol engine paired with a 48-volt mild-hybrid system, producing up to 150kW of power and 320Nm of torque. It’s the least powerful engine in the GLC range, but still manages to feel punchy when you need it to.

This all-wheel-drive variant is paired with a nine-speed automatic transmission. While it can feel a little twitchy at lower speeds when the auto start/stop system is active, it’s otherwise a smooth and well-matched combination for everyday driving.

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 GLC200 has an official combined cycle (urban/extra-urban) fuel consumption figure of 7.5L/100km and with its 62-litre fuel tank, you’re looking at a theoretical driving range of up to 826km which are solid figures for a family cruiser.

In real-world testing, I averaged 7.8L/100km, mostly around town with one longer trip thrown in. Overall, I’m pretty happy with its efficiency.

Mercedes-Benz recommends a minimum of 95 RON premium unleaded petrol for this model.

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).

Despite having the ‘baby’ engine in the range, the GLC200 doesn’t feel underpowered. Power delivery is generally quick, and there’s enough in reserve when you need to get up to speed or overtake. It’s responsive and confident in everyday driving.

That said, the auto start/stop feature is frustrating around town, especially at give way signs or roundabouts where you’re more likely to pause than come to a full stop.

It will cut the engine, and then when you want to accelerate, there’s a delay - sometimes even a little rollback. Not ideal, and definitely something that takes away from the otherwise polished drive.

The suspension hits a lovely balance, it’s forgiving but not floaty. You feel the road just enough to stay connected without it ever feeling harsh, which means the ride stays smooth and composed. It’s also a lovely highway cruiser, easily settling into long stretches with comfort and ease.

Visibility is solid, with minimal blind spots thanks to slim pillars, and the steering is responsive. It corners with confidence, too, with very little body roll, which isn’t always the case in a mid-size SUV.

Parking is straightforward thanks to a clear 360-degree camera system and park assist. The reversing camera turns with the steering wheel, which takes a moment to adjust to, but ultimately makes tight manoeuvres that little bit easier.

The GLC carries a maximum five-star ANCAP safety rating, based on testing conducted in 2022. It scored an excellent 92 per cent in both adult and child occupant protection, which gives plenty of peace of mind for families.

It’s also well-equipped when it comes to safety tech. There are 10 airbags in total, including a front centre airbag and side chest airbags for both rows; a solid showing in this segment.

Even without the optional Plus Package, the GLC comes loaded with safety features including blind-spot monitoring, side exit assist, lane departure alert, lane keeping aid and traffic sign recognition.

There's also driver attention warning, a 360-degree camera view, front and rear parking sensors, forward collision warning, intelligent seatbelt reminders and rear cross-traffic alert.

With the Plus Package, you add interior and exterior monitoring systems, along with something called 'Pre-Safe Impulse Side'; a clever feature that gently moves front occupants away from the doors if a side impact is imminent.

Autonomous emergency braking is also included, with pedestrian, cyclist, car and backover detection. It operates from 7.0-80km/h (or up to 250km/h for vehicles), which is slightly higher than most systems that usually activate from 5.0km/h.

In the back, there are ISOFIX child seat mounts on the outboard seats and three top-tether anchor points across the row.

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 GLC is backed by a five-year/unlimited kilometre warranty, which puts it on par with key rivals in this space. Servicing intervals are generous, too, at every 12 months or 25,000km. Great news if you rack up a lot of kilometres.

But the catch? Servicing costs are steep. Mercedes-Benz offers pre-paid servicing plans in three-, four-or five-year bundles, and the five-year package will set you back $7350. That averages out to almost $1500 per visit. Oof.

For comparison, the Audi Q5’s five-year plan is $3520, and BMW’s five-year 'Basic Service Inclusive' package for the X3 is $2475. So, while the GLC might win on features and finish, it definitely asks more of you when it comes to ongoing costs.
