Mercedes-Benz GLE-Class vs Audi Q7

What's the difference?

There’s little wonder the GLE63 S is back for a second go around, after  clearly putting the frighteners on the Audi RS Q8 and BMW’s X5 M Competition and X6 M Competition.

After all, it’s a large SUV that sacrifices little in the way of practicality (especially the wagon) in its pursuit of high performance.

And for that reason, we’re itching to go for another drive – with or without the family.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.

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.

First things first, the new GLE63 S is available in two body-styles, with the wagon appealing to the traditionalists out there, while the coupe targets the style-conscious.

Either way, few large SUVs are as imposing as the GLE63 S, which is a good thing considering it wants to be taken seriously.

Up front, it’s immediately identifiable as a Mercedes-AMG model thanks to its distinctive Panamericana grille insert.

The angry look is punctuated by the angular daytime running lights integrated into the Multibeam LED headlights, while the chunky front bumper has large air intakes.

Around the side, the GLE63 S stands out with its aggressive wheelarch extensions and side skirts, with the wagon getting 21-inch alloy wheels as standard, while the coupe gets 22-inch items.

From the A-pillars onwards, the differences between the wagon and coupe body-styles start to become apparent, with the latter’s roofline much more steeply raked.

At the rear, the wagon and coupe differentiate themselves even more clearly with their unique tailgates, LED tail-lights and diffusers. That said, they do have a sports exhaust system with squared-off quad tailpipes in common.

It’s worth mentioning that the difference in body-style also means a difference in dimensions, with the coupe 7mm longer (4961mm) than the wagon, despite having a 60mm-shorter wheelbase (2935mm). It’s also 1mm narrower (2014mm) and 66mm shorter (1716mm).

Inside, the GLE63 S separates itself with its flat-bottom steering wheel with Dinamica microfibre accents, and multi-contour front seats, which are upholstered in Nappa leather alongside the armrests, dashboard and door shoulders and inserts.

The door bins are of the hard plastic variety. That’s underwhelming in a vehicle that costs this much, as you would hope cow hide – or at least a soft-touch material – would be applied to them.

The black headliner acts as another reminder of its performance focus, and while it makes for a darker cabin, metallic accents feature throughout, while the trim (our test vehicle had open-pore wood) adds some variety alongside the ambient lighting.

That said, the GLE63 S is still filled to the brim with cutting-edge technology, including two 12.3-inch displays, with one the central touchscreen and the other a digital instrument cluster.

Both use Mercedes’ MBUX multimedia system and feature Apple CarPlay and Android Auto support. This set-up is still the benchmark, thanks to its speed and breadth of functionality and input methods, including always-on voice control and a touchpad.

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.

Being a large SUV, you’d expect the GLE63 S to be quite practical, and it is, but what you wouldn’t expect is the coupe to have 25L more cargo capacity than the wagon, at a generous 655L, due to its higher window line.

That said, when you stow the 40/20/40 split-fold rear bench via the second row’s release latches, the wagon has a significant 220L advantage over the coupe, at a cavernous 2010L, thanks to its boxier design.

Either way, there’s a small load lip to contend with, making loading bulkier items a little more difficult, although that task can be made easier with the flick of a switch, as the air springs are able to lower the load height by a handy 50mm.

Better yet, four tie-down points are on hand to help secure loose items,  alongside a couple of bag hooks, while a space-saver spare resides under the flat floor.

In the second row, things are even better, with the wagon offering a crazy amount of legroom behind our 184cm driving position, as well as two inches of headroom for me.

With its 60mm-shorter wheelbase, the coupe naturally sacrifices some legroom, but it still provides three inches of legroom, while its sloping roofline trims headroom to an inch.

No matter the body-style, the five-seat GLE63 S is wide enough to seat three adults abreast with few complaints, with the transmission tunnel on the smaller side, meaning there’s plenty of room for feet.

There’s also plenty of room for child seats, with two ISOFIX and three top-tether anchorage points on hand for fitting them.

Amenities-wise, rear occupants are treated to map pockets on the front-seat backrests, as well as a fold-down armrest with two cupholders, while the door bins can accommodate a couple of regular bottles each.

A  fold-out cubby is positioned below the air vents at the rear of the centre console, containing two slots for smartphones as well as a pair of USB-C ports.

In the first row, occupants have access to the centre console’s cubby, which features two temperature-controlled cupholders, in front of which are a wireless smartphone charger, two USB-C ports and a 12V power outlet.

The central storage bin is pleasingly large and contains another USB-C port, while the glovebox is also on the larger side, and you get an overhead sunglasses holder too. Stunningly, the front door bins can take three regular bottles apiece. Not bad.

While the wagon has a large, square rear window, the coupe’s is a letterbox in comparison, so rearward visibility isn’t one of its strong suits.

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 entry-level 45 TDI variant kicks off the new Q7 line-up from $101,900, plus on-road costs – $4100 higher than its direct predecessor, although Audi claims more than $15,000 of value has been added.

Meanwhile, the mid-range 50 TDI version tested here costs $6000 more than before, at $112,900, in exchange for more than $20,000 of added value. It can also be had in S line guise for an $11,000 premium.

Standard equipment not already mentioned in the 50 TDI includes matrix LED headlights, dusk-sensing lights, rain-sensing wipers, 285/45 tyres, a tyre repair kit, auto-folding side mirrors (with heating and auto-dimming), and a hands-free power-operated tailgate.

Inside there's, satellite navigation (with live traffic updates), Android Auto and wireless Apple CarPlay support, digital radio, a windshield-projected head-up display, keyless entry and start, power-adjustable front seats with heating, four-zone climate control, a power-adjustable steering column, an auto-dimming rearview mirror and ambient lighting.

Not only are the rivalling BMW X5 xDrive30d ($117,900) and Mercedes-Benz GLE400d ($124,400) more expensive, but neither matches the Q7 50 TDI on value-for-money.

The GLE63 S is powered by Mercedes-AMG’s ubiquitous 4.0-litre twin-turbo V8 petrol engine, with this version pumping out a hard-hitting 450kW of power at 5750rpm and 850Nm of torque from 2250-5000rpm.

But that’s not all, because the GLE63 S also has a 48V mild-hybrid system called EQ Boost.

As its name suggests, it has an integrated starter-generator (ISG) that can provide up to 16kW and 250Nm of electric boost in short bursts, which means it can also reduce the sensation of turbo lag.

Mated to a nine-speed torque-converter automatic transmission with paddle-shifters, and Mercedes-AMG’s fully variable 4Matic+ all-wheel-drive system, the GLE63 S sprints from a standstill to 100km/h in just 3.8 seconds, in either body-style.

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 GLE63 S’s fuel consumption on the combined-cycle test (ADR 81/02) varies, with the wagon achieving 12.4L/100km, while the coupe needs 0.2L more. Carbon dioxide (CO2) emissions are 282g/km and 286g/km respectively.

When you consider the high level of performance on offer, all of these claims are fairly reasonable. And they’re made possible by the engine’s cylinder-deactivation technology and the 48V EQ Boost mild-hybrid system, which has coasting and extended idle-stop functionality.

That said, in our real-world testing with the wagon, we averaged 12.7L/100km over 149km. While that’s a surprisingly good result, its launch drive route mainly consisted of high-speed roads, so expect a much higher number in metropolitan areas.

And in the coupe, we averaged a higher but still respectable 14.4L/100km over 68km, although its launch  route purely involved high-speed country roads, and you know what that means.

For reference, the wagon has an 80L fuel tank, while the coupe has an 85L unit. Either way, the GLE63 S only takes more expensive 98RON premium petrol.

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.

Make no mistake, the GLE63 S is a big beast, but it certainly doesn’t act its size.

Firstly, the GLE63 S’s engine is an absolute monster, helping it to hunker down off the line and then charge on towards the horizon with serious vigour.

While there’s so much initial torque to begin with, you still get the added benefit of the ISG, which helps to eliminate lag as the new twin-scroll turbos spool up.

That said, acceleration isn’t always brutal, as the electronic stability control (ESC) is often quick to cut power when under full throttle in  first gear. Thankfully, engaging the ESC system’s Sport mode solves this issue.

This behaviour is somewhat ironic as the 4Matic+ system is seemingly never short of grip, with it's working hard to find the axle with the most traction, while torque vectoring and a rear limited-slip differential proportion torque from wheel to wheel.

Regardless, the transmission provides predictably smooth and predominantly timely gear changes, although they’re definitely not dual-clutch quick.

What’s more memorable, though, is the sports exhaust system, which keeps your neighbours relatively sane in the Comfort and Sport drive modes, but will drive them mad in Sport+, with hilarious crackles and pops heard loud and clear on the overrun.

It’s worth noting that while the sports exhaust system can be manually engaged in the Comfort and Sport drive modes via a switch on the centre console, it only makes the V8 rumble grow stronger, with the full effect only unlocked in Sport+.

Of course, there’s more to the GLE63 S experience, like the fact that  it somehow rides like a large SUV yet handles like a sports car.

The suspension’s air springs and adaptive dampers offer up a luxurious ride in the Comfort drive mode, with the GLE63 S wafting along with confidence. Not even its large-diameter alloy wheels pose too much of a threat to this quality on poorer country roads.

The ride is still more than liveable in the Sport drive mode, although the adaptive dampers become a  too firm in Sport+, with the ride becoming a little too jittery to be bearable.

Of course, the whole point of the adaptive dampers becoming progressively firmer is to help the GLE63 S handle even better, but the real revelations here are the active anti-roll bars and engine mounts, which effectively limit body roll to such a level that it’s almost imperceptible.

In fact, overall body control is impressive, with the GLE63 S not feeling like the 2.5-tonne-plus behemoth it is. It really has no right to attack corners the way it does, with the coupe feeling a touch tighter than the wagon, thanks to its 60mm-shorter wheelbase.

Further confidence is afforded by the sports brakes, which include 400mm discs with six-piston calipers up front. Yep, they wash away speed with ease, which is exactly what you’d hope for.

Also key to the handling is the electric power steering, which is speed-sensitive and has a variable ratio. It’s really quick in the wagon, and even more so in the coupe, thanks to its more direct tune.

Either way, this set-up is well-weighted in the Comfort drive mode, with plenty of feel and just the right amount of heft. That said, Sport and Sport+ make it gradually heavier, but neither make the driving experience better, so stick with the default setting.

Meanwhile, Noise, Vibration and Harshness (NVH) levels are pretty good, although tyre roar is consistent at highway speeds, while wind whistle is prominent over the side mirrors when travelling above 110km/h.

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.

ANCAP awarded the Q7 range (excluding SQ7) a maximum five-star safety rating in 2015.

Advanced driver-assist systems extend to autonomous emergency braking (with pedestrian detection), lane-keep and steering assist, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control (with stop and go functionality), driver attention alert, hill-descent control, hill-start assist, tyre pressure monitoring, surround-view cameras, and front and rear parking sensors.

Other standard safety equipment includes eight airbags (dual front, front and rear side, and curtain), electronic stability and traction control systems, anti-skid brakes (ABS), brake assist and electronic brake-force distribution, among others.

As with all Mercedes-AMG models, the GLE63 S comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.

Better yet, the GLE63 S’s service intervals are relatively long, at every year or 20,000km – whichever comes first.

It’s also available with a five-year/100,000km capped-price-servicing plan, but it costs $4450 in total, or an average of $890 per visit. Yep, the GLE63 S isn’t exactly cheap to maintain, but you expected that.

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.
