Mercedes-AMG GLE53 vs Audi Sq6 E-Tron

What's the difference?

The GLE Coupe isn't going to click with a traditional enthusiast but will appeal to a new age of mainstream performance buyers. It's a total tech showcase and you can feel all of those 48-volt benefits from behind the wheel.

Love it or hate its shape, then, you have to appreciate how Mercedes has gone to the nth degree on the details on an SUV it probably could have sold on looks alone.

When it comes to a performance electric SUV, the Audi SQ6 e-tron is a fine example and showcases a masterclass in design. It drives and handles beautifully, even if it’s not as fun as I expected.

The technology looks amazing and I'm sure the little bumps we experienced will be ironed out with a software update.

The SQ6 will suit a smaller family best but the decent driving range and fast charging capabilities means regional families might like it too.

Hate the very concept of a large SUV coupe or not, you have to at least agree this second-generation GLE Coupe looks infinitely better than the model preceding it.

This time the Coupe version was front of mind from the outset of the GLEs development and is significantly different from the wagon version in more ways than just a sloping roofline.

The wheelbase has been cropped in 60mm compared to the wagon, and the GLE Coupe is a full 7.0mm wider and 39mm longer than its predecessor.

All this adds up to an imposing and more resolved SUV Coupe. I especially like the way its bootlid flicks up into a spoiler, and how the tail-lights round out the profile nicely.

Still, there's always going to be something a little off about the proportions when it comes to a coupe SUV this big, and it's certainly a re-imagining of what a sporty vehicle should look like.

This car's cabin is almost as confronting as its exterior. Up front you're met with an assault of chrome, a ventilation overload and a totally dominant expanse of screens.

This all hints at the advanced tech which lies beneath, but the real wood and leather trims also elevate the cabin to something you might expect at the tall asking price.

It may appeal to a particular taste and makes the BMW X6's cabin look almost conventional.

The SQ6 has a distinct look compared to the other mid-size SUVs in Audi’s stable with panelling that lacks some of the severe pleating of its cousins, instead incorporating swoopy lines and a more pronounced moulding around the base of the car.

The sporty S styling is seen in the large 21-inch alloy wheels and red calipers but the customisable light designs inside and out really make this stand out.

The interior is sumptuously styled with Nappa leather and suede upholstery and trims, and sports front seats, while the use of displays in the dashboard makes the SQ6 feel like a spaceship.

However, the main panel curves towards the driver and it still feels accessible and intimate for a cockpit. The cabin looks as expensive as what you’d want it to look like at this price point.

In some ways, the GLE Coupe makes the most of its extra dimensions, but in other more obvious ways, it's quite compromised.

Benz tells us there's now 40 litres of combined cabin storage, and with the large door bins, centre console box, convertible cupholders, and glove box, I'm inclined to believe them.

The brand also told us much of the extra 39mm of body length has gone into the rear passenger space, and this seems true when it comes to legroom.

You definitely notice the decline of the C-Pillar, though, making an otherwise large space feel slightly claustrophobic, particularly with the 53's dark headlining and heavily tinted rear windows.

The almost absurd ride height does make peering over the bonnet a chore at times, although I enjoyed the adjustability and comfort afforded by the front two seats.

In terms of connectivity, front passengers get a plethora of USB-C jacks, a wireless charging bay, and a 12V power outlet. There's no USB-A connectivity, so you'll want to stock up on converters.

Rear passengers benefit from dual USB-C ports in a fold out tray, and also score dual adjustable air vents. Two extra climate control zones can be optioned for rear passengers ($1450), and there's also an exorbitant option package to include two screens and wireless headsets for the full business-class experience in the back seats ('Entertainment Package' - $6000!).

You might be surprised given this SUV's shape, but a lot of thought was also poured into the design of the boot area. Thanks to a large footprint, the GLE 53 Coupe's boot is large at 655 litres, five litres up on its predecessor. It's still a whopping 170-litres down on the wagon version, though.

The boot lip has been lowered significantly to increase ease of use, too.

Our test car did not have a spare wheel, with only an inflator kit or run-flat tyres to be working with. This is despite a large area under the boot floor which, to my eyes at least, could easily have fit a space-saver spare.

The cabin's primary objective seems to be one of passenger comfort. Everything you touch feels soft under hand and while seat padding is on the firmer side, all but the rear middle seat is comfy on a longer journey because of their extra functions.

The rear-row back rest has two recline positions and the seat beds offer long under-thigh support. The middle seat bulges up, and coupled with the compromised legroom, it won't be a nice seat for an adult.

The front row offers the best legroom and there is enough space in the rear for my six foot three brother to squeeze into (somehow) but I wouldn't want to be in the rear for a longer journey if you're super tall.

Access is good for each row with wide door apertures and seats that aren't positioned too high. There will be no groans getting in and out of the SQ6.

Up front the glovebox and middle console shoulder most of the storage burden but there is a handy flip-down drawer at the driver's knee for a wallet and a centre console with the charging stuff but it is an awkward space that could have been better utilised. Things tend to move around in there if not secured.

In the rear there are a couple of net map pockets, storage bins and a total of four drink holders but that's about it. The other amenities back there soften the lack of storage options as you get directional air vents, climate control, heated outboard seats and a couple of USB-C ports.

The technology on a whole looks amazing and the touchscreen multimedia display is responsive and logically laid out. You'll be able to figure it out quickly and I like that important functions, like climate control, and shortcuts are pinned to the screen as it makes it easier to access them when on the go. The Audi voice assistant can be activated by 'Hey Audi' if you don't want to fiddle with screens on the road.

The wireless Apple CarPlay was simple to set up but at the beginning of the week it did tend to get booted whenever the climate or massage functions were activated. This was annoying as you'd have to reselect CarPlay and jump back into whatever app you were in and when you're using the Map app, it feels disjointed. However, this sorted itself out by the end of my week.

On the whole, all the screens and their functions are user friendly but there were a couple of gremlins that needed a car restart to fix. Randomly, my volume became useless and the touchpad/buttons on the steering wheel stopped working.

I do like a normal button over touchpad controls as I find them more responsive but the touchpad controls on the driver's door were really easy to use and I like the family-friendly option of being able to individually apply the child-lock to the rear doors.

Rounding out the cabin is the large 526L boot which offers a level loading space and the ability to adjust the height via the adaptive S air-suspension from buttons in the rear.

The rear row has a 40/20/40 split, which opens up storage options again and there is a deep under-floor storage pocket that houses the tyre repair kit. A handsfree-powered tailgate comes standard, which I always appreciate and the massive frunk (64L) takes care of all of the cable storage.

The launch of the flagship SQ6 e-tron brings the Q6 line up to three before a high-performance RS hits our shores sometime in the future. However, this new variant is priced at $151,400 before on-road costs and that's a hike of $28,900 over the mid-spec Q6 e-tron quattro.

Is it worth the jump? Mostly because this model has almost every feature that is found as an at-cost extra or pack for the other variants but it does miss out on a ventilation function for the front seats and at this stage Audi is saying it's not available to add, which is odd for a top model grade.

With the motor outputs and performance tweaks, the SQ6 competes in the world of the Porsche Macan 4S as they are mechanically related but you can pick up the 4S for $149,300 MSRP and the SQ6 can't match it's torque output of 820Nm.

The most exciting thing about the Q6 range in general is the technology and the SQ6 is no different. The dashboard is a visual feast for the eyes with a 14.5-inch multimedia display, an 11.9-inch digital instrument cluster, and a 10.9-inch touchscreen for the front passenger.

There is wired/wireless Apple CarPlay and Android Auto, built-in satellite navigation and because the system is run by Android Automotive there are a whole bunch of downloadable apps like Spotify, YouTube and Amazon Alexa voice assistant on top of the connected Audi App. These apps are accessible from the passenger display, which means they can scroll the news or watch a video on a longer trip.

There is also the upgraded 3D Bang & Olufsen surround sound system, a colour augmented reality head-up display (the screen is basically a dynamic 3D setup) and three-zone climate control.

Charging is taken care of with four USB-C ports (2/2), a 12-volt socket that moonlights as an actual cigarette lighter (complete with an nearby ashtray) and a wireless charging pad with its own 'arm' that secures your phone.

The LED lights at the rear can be customised with different light signatures which are downright cool and the front LED lights also have animated individual pixels that do a little light show when you turn on the car (to the delight of my child).

Other highlights include front sports seats with heat and massage functions, wine-red Nappa leather upholstery and black suede trims, a heated steering wheel, panoramic sunroof, heated rear outboard seats, and a handsfree powered tailgate.

Audi also includes three charging cables and a one-year subscription for Chargefox public charging stations for free, as well as installing an at-home 7kW charger, which is a nice way of making a new owner feel valued.

Here's where this car gets particularly interesting. It's a hybrid. But not your gran's Prius. It's hybrid in a way which will make you re-think the technology.

Residing under the bonnet is a 3.0-litre, twin-turbo, straight-six engine mated to a very complex looking nine-speed (torque converter) automatic transmission.

One of those two turbochargers is driven by an electric motor rather than the exhaust (in order to provide its peak benefits at the lowest possible rpm), and there's also an electric motor inside the transmission which takes the load off the engine at low speeds and between gears.

This isn't where the 48-volt tech ends, with the GLE 53 also sporting active anti-roll bars and dampers, which significantly adjust the ride and body-roll on-the-fly.

All four wheels are driven via Benz's 4MATIC+ all-wheel drive system.

The SQ6 is a fully electric all-wheel drive and has two motors, one located on each axle. Together they produce up to 380kW of power and 580Nm of torque, which means this can do a 0-100km/h sprint in just 4.3 seconds when the launch control is activated.

There are three regenerative braking levels and a one-pedal mode which can be selected by sliding the gear-selector into 'B' otherwise the other two modes can be selected via the paddles on the steering wheel. You'll get the best efficiency when B is selected but it does take a beat to get used to and if you time your stops right, it can function as a proper one-pedal action.

It's a performance car, so fuel consumption is probably not going to be front of mind for potential buyers. That said, the hybrid tech delivers a surprisingly good number.

The official combined cycle consumption number is ambitiously under 10L/100km at 9.3L/100km.

After three days of (roughly) combined testing and about 300km of distance travelled, our car was showing a dash-reported 14.1L/100km. Not near the claim, but is it really bad for a performance SUV weighing 2447kg? I would argue, not.

The GLE 53 requires the top-shelf 98 RON hydrocarbons to fill its 85-litre tank, giving it a maximum theoretical range of 726km between fills.

The SQ6 has a lithium-ion battery with a large 100kW capacity and can accept up to 270kW on DC power, which is excellent. There are two Type 2 charging ports (on either side of the car) and one has a CCS enhancement which means you can charge this from 10 to 80 per cent capacity in as little as 21 minutes on a 270kW ultra-rapid DC charger.

It is more common to see a 50kW DC charger though and that charge time sits closer to an hour and 20 minutes.

On a home 7.4kW charger, you'll get the same percentage after 15 hours, perfect for an overnight recharge.

With a claimed WLTP driving range of up to 568km and energy consumption between 17.5 and 18.6kWh/100km, the daily commute and odd family road trip is more than covered with this model.

My average consumption popped out at 18.1kWh based on the trip computer and that’s a good result for how hard I’ve pushed it over country roads, in the city and on the highway. 

This Benz feels about as imposing from behind the wheel as it is to look at. Straight away, you'll notice you tower over the road. I felt as though I was sitting high enough to be on the roof of passing hatchbacks, so there's nothing traditionally 'sporty' about it from the get-go.

I know you're probably thinking visibility is average with that roofline, and you'd be right. You just can't see much, full-stop, out the back.

Thankfully, an array of sensors and very wide-angle mirrors help with overall visibility, so you won't have to be too paranoid about unseen vehicles in your blind spots.

I'm pleased to report all the technology which goes under this SUV's skin is evident when it comes to the drive experience.

The hybrid tech is ultra-slick and impressive in every department, from trawling in traffic to the curvy stuff and the open road.

The responsiveness of this powertrain is something to be experienced (with the pre-spooled turbo) and the way the hybrid motor in the transmission smooths out shifts removes all the worst characteristics of a traditional torque converter automatic.

One thing to note about the GLE 53 – while it's quick, it's not quite a fire breather. There's no getting around this car's almost two and a half tonne weight, and while I love the smooth feel and note of the 3.0-litre straight six, it's simply not as thunderous or full of theatre as I imagine the 63 S will be.

Despite its height and weight, the altered steering ratios and 48-volt driven suspension and anti-roll systems cause a suspense in belief when it comes to the corners.

And grip levels are certifiably absurd with those gigantic rear tyres also pitching in to do their part to help something this large deny gravity and physics.

It's not all amazing though. You really feel every millimetre of this SUVs width, and at the end of the day there's no getting around it. It just doesn't feel anything like a sports machine in the traditional sense.

When it comes to ride quality, the GLE impresses, but has its limits. Sure there's air suspension at work, but it offers up nowhere near the ride quality of the more comfort-tuned GLC 300e I recently tested.

Seems as though there's an inevitable cost to keeping the GLE feeling well and truly planted at all times.

On the freeway the GLE Coupe is ridiculous in the way it can basically drive itself, so this offers up a real plus for those looking for a balance of performance and sensibility for longer trips.

Outside of the initial acceleration thrill, I have to say that the SQ6 sort of drives like a lot of the other Audi SUVs I’ve sampled. Which is fine because it’s dynamic and handles beautifully on the highway or city but it’s just not as fun as what I was hoping it would be. The power will satisfy everyone though. 

The different driving profiles and adaptive S air suspension really personalises the on-road experience when you want it and my favourite profile is Dynamic as the suspension and steering feels more performance focused, which I prefer. 

Ride comfort is up there with the best and you won’t really be bothered by the bumps in the road, even with the stiffer suspension, but road noise does creep in at higher speeds. 

The visibility all round is good despite thicker pillars but the rear visibility is narrow even before a car seat or passengers are back there. A digital rearview mirror would have been handy here. 

Just something interesting to note is that when you accelerate from a full stop, there can be a small lurch as if it’s rolled backwards or the brakes have held a tad too long. It’s so quick when it happens that it’s not annoying but it is noticeable in stop/start traffic.

The SQ6 is really simple to park and navigating small car parks feels like a dream. The dimensions are forgiving and the 360-degree camera system is top notch. 

The SQ6 is covered by a maximum five-star ANCAP safety rating from testing done in 2024, and features nine airbags which includes side chest airbags for the second row but it’s more common to see those just on the first row so it's nice to see on a family car.

There’s a host of safety equipment included but standouts are the emergency call capability, and safe exit assist which will delay your door from opening if it detects a car or cyclist which is a handy feature if you have a kid that throws open their door like mine.

Other equipment includes driver attention warning and alert, blind-spot monitoring, tyre-pressure monitoring, intelligent seatbelt warning, adaptive cruise control with stop/go function, lane departure warning, lane keeping assist, emergency lane keeping, park assist, front/rear parking sensors, 360-degree camera system, rear cross-traffic alert, and traffic sign recognition.

There is auto emergency braking (AEB) with forward collision warning, car, pedestrian, cyclist and junction turning assist which is operational from to five to 250km/h.

There are ISOFIX child seat mounts on the rear outboard seats and three top-tether anchor points but two seats will fit best. Front passenger space might get cosy when a rearward facing child seat is installed but I had no issue fitting my big booster seat this week.

Mercedes has recently made a jump to the front of the luxury segment, offering an industry-wide standard of a five-year/unlimited kilometre warranty. Here it is only rivalled by Korean newcomer, Genesis.

Service intervals occur once every 12 months or 25,000km and prices can be pre-packaged at a discount.

A three-year service plan can be had for $2800 ($3500 if you choose to 'fix' the price), four years can be had at $3800, while a full five-year plan will set you back $5200. Not cheap, but then, neither is the car itself...

The SQ6 is covered by Audi’s five-year/unlimited kilometre warranty and the battery is covered by an eight-year or up to 160,000km warranty, which are all standard terms for the class.

Audi also offers six years of complimentary roadside assistance and a servicing program for six years that costs $2080, which is competitive, and servicing intervals are at every two years or 30,000km. 

Audi includes the installation of a 7.4kW AC home charger, three charging cables and a one-year Chargefox public charging subscription with this model.
