Audi Q7 vs Mercedes-Benz GLC-Class

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 GLC43 will inevitably remain one of AMG's more popular models, given Australian apetites for performance cars and the popularity of the mid-size SUV segment.

While the GLC doesn’t move the game forward massively aside from its new engine - which is a huge plus for the SUV - BMW has a new generation of X3 on the way, which will undoubtedly feature a performance variant.

And keen drivers should keep in mind that Porsche’s impressive Macan SUV is available in sharp-driving variants like the GTS for not much more, or even an S for notably less. And chances are, they’ll be more satisfied on a winding or twisty road. However stock of the ICE Macan will run out soon.

But the AMG offers a balance between convenience, comfort, and performance that will suit plenty of customers, rather than excelling in one particular area.

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 AMG GLC43, as you’d expect, has a few immediate give-aways that it’s no regular GLC300.

The vertical grille slats, the lower part of the apron featuring covered-up intake-style designs, and a different set of 20-inch AMG wheels are the easiest things to spot.

But the aforementioned Night pack, which adds black trim to the performance SUV, as well as the quad-exit exhaust tips instead of dual-exit on the GLC300 might be the most quantifiable way to explain the differences to the uninitiated.

In terms of dimensions, the GLC43 is now 67mm longer for the SUV, or 43mm longer in Coupe form. Both have an 11mm wider wheel track, and a 15mm longer wheelbase.

Inside, it’s quite similar to the 300, save for the AMG steering wheel and elements like the contrast stitching in the leather upholstery.

While other - especially more luxury-focused - Mercedes models have moved to a new interior design language with features like the Superscreen or Hyperscreen spanning the dash, the GLC’s interior still looks and feels suitably premium, and hasn’t dated much since being introduced.

The same can be said for its exterior, following relatively small changes over the still good-looking previous generation.

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 GLC’s interior feels more spacious than in its predecessor, and its ergonomics have been improved a little with the removal of elements like the touchpad control for the multimedia.

The software itself is quite easy to use on the touchscreen itself, removing the need for a physical control, and it’s rather customisable. 

Users are able to even adjust what order the drive modes appear in, and change what the two AMG Dynamic Select control dials on the steering wheel display or change.

The wheel itself is comfortable to hold, but its two-tier rows of controls and the lack of distinct physical buttons is a downside.

There is however plenty of storage, the central cubby and glovebox have space for all your assorted bits and pieces, and the door cards are able to accommodate even the biggest of bottles.

In terms of seats and comfort, the GLC’s cabin doesn’t feel cramped at all, with the seat itself supportive and adjustable to an impressive extent.

Space in the second row is comfortable rather than massively generous, but feels more spacious thanks to plenty of light via the sunroof.

The Coupe’s rear seat also does a decent job of accommodating average-heighted adults.

Behind that, 620L of boot space in the SUV and 545L in the Coupe are 40 and 45 litres more than the previous models, respectively.

Kicking off from $136,400 before on-roads for the SUV or $146,900 for the SUV Coupe, the AMG GLC’s pricing puts it roughly against the likes of the BMW X3 M40i or the Porsche Macan GTS, formidable rivals for sure.

To bring more than just its AMG bite and bark, the GLC43 comes with a reasonable list of kit, mostly borrowed from the GLC300 - the original launch variant of the mid-size Mercedes SUV.

That means it comes with a reasonable list of features like an 11.9-inch multimedia touchscreen with the brand’s MBUX software, a head-up display over the 12.3-inch driver display, a large sunroof, wireless phone charging, heated electrically adjustable front seats, wireless Android Auto and Apple CarPlay and a Burmester 3D sound system.

In terms of design and materials the GLC43 features a leather interior upholstery with an AMG Performance steering wheel in Nappa leather, but it’s mostly the exterior where the design departs from the GLC300.

An AMG exterior styling pack and the Night Package are both standard - for the first time on the SUV in Australia - and mean black trim highlights, a set of 20-inch AMG multi-spoke light-alloy wheels and the Urban Guard Vehicle Protection Plus package are standard.

The optional $6900 Performance Ergonomic Pack adds AMG Performance front seats, which hold front occupants in place a little more snugly, and add a Nappa leather/Microcut microfibre wrap to the steering wheel.

Aside from the different body style, the main difference between the wagon SUV and Coupe is that the aluminium roof rails are absent for the latter.

Another first for the GLC is the inclusion of rear-wheel steering, which enables the rear wheels to turn 4.5 degrees opposite to the fronts at low speeds for extra manoeuvrability, or 0.7 degrees in the same direction when travelling above 100km/h for extra stability - I’ll come back to this later.

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.

This is where the AMG version of the GLC really outshines the ‘standard’ GLC300, and starts to justify the extra ask over its $103,370 sticker price.

Like the GLC300, the AMG GLC43 has a turbocharged 2.0-litre four-cylinder petrol engine, which is paired with a nine-speed automatic transmission sending drive to all four wheels.

But unlike the 300, the AMG GLC43 borrows its engine from the likes of the AMG A45S, the M139 engine which puts out 310kW and 500Nm thanks to some seriously impressive engineering - and a lot of turbo pressure.

AMG’s one builder, one engine policy (they call it “One Man, One Engine”) means each engine in a GLC43 has been built by a sole expert engineer who has been certified to a high degree.

A 48-volt ‘mild-hybrid’ system is also present in the GLC43, which helps keep the turbocharger spinning (at up to 175,000rpm) to be more responsive, eliminating turbo lag.

The nine-speed auto is also slightly higher-tech than the GLC300’s, a wet start-off clutch replaces the traditional torque converter, which AMG says is lighter and more responsive - also featuring a double de-clutch function for faster shifts.

The AMG Performance version of the 4MATIC all-wheel drive system permanently diverts power to all four wheels with a 31 to 69 per cent front-rear distribution.

Mercedes-AMG claims the GLC43 is able to hit 100km/h from stand-still in just 4.8 seconds.

For reference, the old GLC43 (with a turbocharged inline six) made 287kW/520Nm and was a 4.9sec to 100km/h car.

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.

Mercedes-Benz says the AMG GLC43 consumes 9.7 litres for every 100km travelled in an SUV, or 9.9L/100km in the Coupe version, We were unable to properly test both of these figures on the launch.

Both have the same 62-litre fuel tank, and require premium RON 98 fuel.

CO2 emissions are rated at 219g/km for the SUV and 223g/km for the Coupe.

On test, after an hour of driving the GLC43 quite dynamically, the fuel consumption displayed on the trip computer sat around 15L/100km, so regular driving is sure to return a figure closer to Mercedes’ claim.

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.

A long drive loop that consisted of limited sections of tight twisty roads meant getting to know the GLC in an intimately dynamic sense proved tricky, but what stands out about the mid-size SUV from Affalterbach is how much its ability in cornering belies its size.

The rear-wheel steering makes a big difference for the otherwise sizeable SUV, and even though the it weighs 1976kg (53kg more than before; the Coupe is 94kg heavier than before at 1998kg), the 4MATIC all-wheel drive keeps the GLC’s purchase on the road in check.

Suspension is relatively stiff for a family SUV even in Comfort, though adjustable, as one of the many aspects able to be customised through the multimedia screen menu or even steering wheel dials.

Steering itself can be adjusted, though is probably fine to leave in Comfort depending on personal preference.

But the hero of this - and any - AMG is the engine, and the M139 works surprisingly well in the big GLC.

Where it turns the A-Class hatchback into a proper supercar fighter, it makes the GLC a relatively muscular yet responsive family hauler.

The 310kW and 500Nm outputs are probably the sweet spot in terms of the GLC43 not feeling like there’s too much for anyone to handle, while still being quick enough to keep a keen driver happy.

On calmer roads, highways and gentle winding country roads, the GLC is comfortable enough with everything set up in the appropriate drive mode, though don’t expect to feel immensely refreshed after hours behind the wheel - it’s still set up for relatively dynamic driving.

Noise and road surface imperfections make their way into the cabin to some extent, though it’s not egregious, while one of the cars on test had a small creaking sound present in the dash, set off by road bumps and corners.

It has 10 airbags, plus a fairly standard (for its class) suite of safety tech including active features like pedestrian warnings, active lane-keep assist, driver attention reminders, parking sensors and cameras for surround-view monitoring, and collision warnings and mitigation.

Of course, the standard features like ABS, stability control, brake assist, auto emergency braking and lane departure warning all feature.

The rear seats feature ISOFIX and a 40/20/60 split fold.

The current GLC has been awarded five stars by ANCAP and scored well in both adult and child occupant protection.

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.

Mercedes-Benz Australia’s warranty is a relatively standard five-year/unlimited kilometre offering, level with rivals like BMW.

Servicing intervals are every 25,000km or 12 months, whichever comes first.

Mercedes’ servicing costs can be covered in packs and for the first three services of a GLC43 SUV it will cost $3445, four for $4552 or five for $6935. These prices are as listed in December 2023, and are subject to change.
