Mercedes-Benz GLE-Class vs Audi SQ7

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 Audi SQ7 TFSI is a delight to drive. You can’t fault its handling or power and drivers who want that sort of performance will not be disappointed. However, for the price point I was hoping for sweeter ongoing ownership costs and terms. It's missing a few family-orientated amenities, particularly in the middle row, but it’s big enough to accommodate a large family and all of its gear. So, I give this an 8.0/10.

My son thought the red paintwork and engine were pretty cool and he also gives it an 8.0/10. 

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.

The SQ7 has always had a certain understated glamour about it. It’s usual to see these cars in the monochromatic hues that European manufacturers seem to favour, so it can slip under the radar a little.

Not our example, in its Matador Red, a colour which accentuates the red calipers behind the 22-inch alloy wheels and makes the LED headlights pop.

The nose is pronounced with only a small ‘SQ7’ badge hinting at what’s beneath the long bonnet.

There’s quite a bit you can customise and one of the options is sporty black accents across the bodywork, as per our test car.

The interior hosts a plethora of soft touchpoints, leather trims and shiny black piano finishes to create a premium finish.

The panoramic sunroof and dark grey headliner (which is apart of that Sensory Package) further enhances the sense of luxury.

The sports seats are finished in a Valcona leather trim that’s diamond quilted but the headrests are fixed, which might not thrill taller occupants.

Overall, the SQ7 is a large SUV being 5067mm long, 1970mm wide and 1743mm high.

Those dimensions almost challenge the Kia Carnival, which is a people mover! Make sure it will fit in your garage before buying it. 

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.

It’s missing a few little family items found on other large SUVs but it’s still a fairly practical family car. The cabin is spacious but passenger comfort has been prioritised over storage options.

Front and middle row occupants enjoy most of the room but third rowers will be comfortable on short journeys.

I would be saving these seats for the kids on longer trips, unless you want to get dagger eyes from any adult passengers stuck back there as the amenities aren’t as extensive as you might like with only two cupholders, a reading light and air vents (which aren’t directional).

With the Sensory Package included, the inside is an example of luxury with its heated and ventilated front seats, as well as the heated outboard seats in the middle row.

I love the massage function up front and that it’s customisable for intensity and position. The heated steering wheel is also a nice feature on the chilly days we’ve been having lately.

The tech is quite good with dual 12.3-inch touchscreens stacked on the dash and centre console.

They have haptic feedback, which means they vibrate when you touch them, but curiously this feature disappears while you’re using the wireless Apple CarPlay.

It did take a little while to get used to the Audi system and the haptic feedback, but once you do it’s easy to handle. There’s Bluetooth, digital radio, wired Android Auto and built-in satellite navigation, too.

The head-up display is super clear and displays the sat nav guidance and speed. What I really love is the four-zone climate control – meaning the middle row can get some further adjustments for ultimate comfort.

Charging options are okay with the front enjoying a wireless charging pad, two USB-C ports and a 12-volt socket. Middle row passengers also get a couple of USB-C ports but third rowers miss out.

I was surprised by the lack of storage throughout and this leads me to think this would suit older families best. For example, the middle console is large enough to only fit a phone. Still, each row gets two cupholders and a drink bottle holder in each door.

The boot is an acceptable size with all seats in use at 295L but with the third row stored, it jumps up to a more respectable 770L. There are stacks of different storage accessories available to purchase, if you need extra space.

The third row is a 50/50 split and the middle row has a very practical 35/30/35 split, which opens up the storage options.

The level load space is handy for the grocery run. But there’s no underfloor storage, and you don’t get a spare tyre, just a puncture repair kit.

A powered tailgate is handy, although this one's a bit faster than others I’ve sampled.

The SQ7 is a performance SUV and that means you’re paying for some heavy-hitting engine specs. As such, expect to pay $166,400 before any on-road costs or optional extras.

That puts it just under the cheapest of its competitors, so it doesn’t feel outrageous for what you get.

Our model has been finished in 'Matador Red' and I was pleased to see paintwork options are included in the base price (as they should be).

Our model does have the 'Sensory Package', which adds $13,300 to the price tag but that bundle includes some cool features like an extended leather dashboard, a synthetic suede headliner, an 'Advanced 3D' 23-speaker Bang & Olufsen sound system, an air quality system (with built-in perfume!), a front seat massage and ventilation function and heated rear outboard seats.

Even without the package, it’s still fairly well-specified with its diamond-quilted 'Valcona' leather trim, HD Matrix LED lighting, customisable ambient lighting, as well as wireless Apple CarPlay and Android Auto to name just a few.

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 new TFSI engine in the SQ7 is monstrous. It’s a 4.0-litre twin-turbo petrol V8 with maximum outputs of 373kW/770Nm.

To say it’s powerful is an understatement. This would be at home on the autobahn and my son cheered whenever I had to get up to speed.

It, of course, replaces the SQ7’s iconic diesel V8. The old TDI unit had 53kW less power but 130Nm more torque. However, the new engine delivers on power with aplomb.

The eight-speed auto transmission glides effortlessly through its changes and the all-wheel drive drivetrain is responsive.

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.

With great power comes… okay fuel efficiency. Actually, better than okay considering the twin-turbo V8 engine. The official combined cycle fuel figure is 11.9L/100km and real-world testing saw my figure at 13.2L.

Considering how hard I drove this and the type of driving I did this week, which was a combo of open-road and urban, this is very respectable. Expect it to be much higher in the city, though.

The SQ7 has a large 85-litre fuel tank and based on the official combined figure, you should be able to get around 714km of driving range. That isn’t as great as more fuel-efficient options but still good for those who like their road trips.

Audi recommends a minimum of 95 RON premium fuel with a preference for 98 RON for ultimate efficiency.

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 performance is awesome and I made excuses all week to hop in and drive it. It doesn’t hurt that when you press the push-button start, the engine rumbles and growls. There’s even a ‘spitting’ sound as the turbo fires up. It all promises fun.

While the power feels immense, you do have to get used to how to handle it. For example, when you first shift into gear and pull your foot off the brake, the car lurches forward as if it’s rearing to go. It took me a couple of days to get used to the little quirks of it. 

The steering is controlled and responsive, adapting to the conditions and speed at which you’re driving. If you’re accelerating hard, the steering turns a little stiff and the seat belt tucks you into your seat, reaffirming the addition of that S in the model name.

The cabin is very quiet and there’s no shuddering or vibration to be felt through the steering or seat.

The SQ7 features sports adaptive air suspension and it's dependant on how you drive and what drive mode you’re in. It makes for an extremely comfortable journey and not just for those in the front. The rear passengers are nicely cushioned, too.

This is a big car but you don’t feel those dimensions when you park it. Even with its 12.4m turning circle, it’s not cumbersome with the adaptive steering.

The dynamic 360-degree view camera is super clear but the parking sensors are too sensitive for my liking. It might just have been an oddity on the particular model I drove but the emergency braking did pop on a few times (scaring the hell out of me every time!).

The SQ7 has a healthy suite of safety features with the following being standard: LED daytime running lights, lane departure alert, lane keeping aid, blind-spot monitoring, rear cross-traffic alert, dynamic 360-degree view reversing camera (it turns with the direction of the steering wheel), dynamic parking guidelines, front and rear parking sensors, rear occupant alert, intelligent seatbelt monitoring and adaptive cruise control.

It also features an active bonnet, meaning it will lift up and away from the engine if the sensors detect that a pedestrian has been hit. As well as an SOS emergency call button.

It has AEB and forward collision warning with car, pedestrian and cyclist detection which is operational from 10-85 km/h (10-250 km/h for car detection). It is usual to see it operational from 5.0km/h, though.  

The SQ7 achieved a maximum five-star safety rating from testing conducted in 2019. It only has six airbags, which is fairly low for a family car, but that does include curtain airbags covering all three rows.

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.

If I was spending my hard-earned cash on a vehicle like this, I would want to be treated like a queen when it comes to servicing.

Manufacturers should sweeten the pot when it comes to on-going servicing and ownership terms when you’re at this level but the SQ7 just comes with a pretty standard five-year/unlimited km warranty.

You can pre-purchase a five-year/75,000km servicing plan and it will set you back a total of $4100 (or an average of $810 per service), which is expensive but not outrageous for a performance vehicle.

Servicing intervals are reasonable at every 12 months or 15,000km, which is good.
