Mercedes-Benz Eqe53 vs Audi Sq8 E-Tron

What's the difference?

In the wild new world of fully electric cars there isn’t really an ‘average’ of what to expect. If there was, I’m sure the EQE 53 would exceed it. Its electrification brings the ambiance of a luxury car, while its performance reminds you of what AMG is capable of.

There’s a bit of the mechanical engagement of AMG missing, a relatively small boot, and some won’t be sold on the function-over-form looks, but the EQE 53 is a pleasantly surprising look at the future of fast Mercedes.

There’s not doubt large, luxury SUVs like the SQ8 have a lot to gain from electrification in terms of refinement, performance and running costs. The flip-side is the extra mass of the batteries and other electrical gear but, in this case at least, there might be a silver lining there in the way the hulking SUV manages to force the air suspension into agreeable submission.

For our money, the station-wagon variant is the one to buy. It’s cheaper to begin with and with its greater luggage capacity, it simply makes more sense. Which is not to say the Sportback version is compromised in luxury, safety or performance terms, but if practicality doesn’t figure highly in any purchasing decision involving an SUV, then we sense a great disturbance in the force.

Regardless of what’s powering the SQ8, the driving experience is vintage Audi and that’s a good thing, and even that massive kerb mass can’t blunt the sort of chassis dynamics and feedback we’ve come to expect from the brand.

Some buyers will possibly baulk at the projected range and the Audi’s appetite for electrons, but when lined up side-by-side with its major competition, the SQ8 is every chance to emerge as the one to buy. We’ll need a proper comparison for that, of course, but the Audi should be on any short-list of big, deluxe, electric SUVs.

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

The EQE is certainly a departure from the classic lines of the current E-Class sedan. Mercedes-Benz has chosen to take a completely new approach for the electric era, embracing the need for ultra-low drag designs, and a corresponding newfound love for curvaceous surfaces.

It’s fairly imposing too with enormous wheels and an abundance of panels. Needless to say some will find this new design direction challenging. It proved quite controversial in the CarsGuide office, at any rate.

I can say it looks a bit more approachable when witnessed in the metal, and the AMG branded 53s I sampled for this review added a few more much-needed points of interest to this single curve of a design.

This is particularly notable around the rear of the EQE 53 which adds a little tail spoiler and glossy rear diffuser, which help accentuate the width and terraced design of the rear window.

Around the front is a little more featureless, with the blanked-out grille losing the intricate three-dimensional appeal of this car’s combustion equivalents. There’s just something a bit plain about the EQE’s face, although Mercedes has tried to spice it up with interesting headlight clusters.

The inside is spectacular, with a smorgasbord of screens and lights to match an abundance of glossy touch-based surfaces. Some may not be sold on the over-the-top approach, but it feels as futuristic as an EV should be.

The material choices are nice, too, with soft-touch materials atop the dash, doors, and running down the centre console. The ambient lighting is particularly flashy, and works in with the consistent single-piece sort of design which makes up the whole dash.

While the LEDs might be a little too much for some, there are some more subtle detailing points, like the way the centre air vents are delicately worked into the flow of the dash, and the rotor designs of each vent at the edges are intricate pieces.

Stylistically, the big news is that the SQ8 is the second model to take up Audi’s latest exterior design language. That includes the two-dimensional Audi grille logo as well as a 'singleframe' (Audi’s own word) light bar that links the matrix headlights.

The SQ8 also gets Audi’s Sport Package as part of the price of admission, and that includes black roof rails and other touches.

Of more technical interest is the way the front of the car has been designed to aid air flow around the front wheels. Controllable flaps in the front fascia as well as underbody winglets keep the air flowing around the wheels without contributing to excess aerodynamic drag at speed.

In an engineering sense, the big news is the adoption of a three-motor layout. While some manufacturers are yet to see the value in this, having a motor on each of the rear wheels means there’s no longer a need for a rear differential.

The EQE is plenty practical up front, with an odd SUV-like seating position providing a commanding view of the road. This seat positioning isn’t an accident or a necessity of facilitating batteries under the floor, but a deliberate design decision by the brand to try to emulate some design choices which have made SUVs so popular.

The result is surprisingly effective, but doesn’t help the view out of the rear of the car, which is a restricted letterbox aspect courtesy of a slinky roofline and tall boot lid.

Still, peering down on the road lets you position and park this large EV more easily. Adjustability isn’t bad for the front passenger, and space is healthy both in terms of width and height. One dimension which can’t be altered is the particularly tall dash height, and while this is largely overcome by the taller-than-average seat, it could be an issue for shorter drivers.

Storage is great, with a big bottle holder and bin in the doors, a huge cutaway below the floating centre console for storage, with an elastic strap for tying down objects. There are a further two bottle holders in the centre console and a bay with a wireless charger, too, and the split-opening armrest box is deep.

One of the more divisive points of this car’s practicality offering is the screen-based functions. Everything has been moved into the massive centre screen. There are no tactile buttons or dials for this car’s functions, with it all controlled through context menus.

To be fair, with the amount of real estate on offer, the touch elements can afford to be massive, and there is a permanent set of climate controls at the base of the screen, but adjusting these functions on the fly is never as easy without physical feedback.

The same goes for the touch-centric wheel controls. Benz says the idea with the four-zoned touch panels on the wheel is to offer unrivalled ability to control the car’s functions even when the wheel is at an angle, but it is also easy to accidentally hit various touch functions, and they can require some delicate action to use properly.

The back seat is impressive. It maintains the tall seating position of the front, letting you look down on the road as though you’re in an SUV, and the comfortable seating and surfaces continue. Legroom is particularly impressive, with leagues of space behind my own driving position. Headroom is even okay considering the descending roofline. It’s quite dark in the EQE 53 we tested thanks to its black-on-black trim, giving the illusion of a space which is smaller than it actually is.

Storage is good, too, with a big bottle holder in the door cards, quad-zone climate control, complete with a separate touch panel for rear passengers, adjustable air vents, and solid clamshell pockets on the backs of the front seats.

The EQE has a boot capacity of 430 litres which doesn’t seem enormous given the footprint of this car, and no doubt has a lot to do with its slinky aerodynamic design around the rear. There’s no ‘frunk’ either so this is a car perhaps more focused on driving and being driven in than its ability to carry things.

There’s absolutely no question Audi knows a thing or two about cabin layouts and ergonomics. Like other contemporary Audis, this one features the fully customisable Virtual Cockpit with a huge range of possible displays and layouts. And again, as usual, it all works seamlessly and efficiently.

The head-up display is amazingly clear and the twin touchscreens divide the car’s tasks logically. Yes, there’s a lot going on, but compare the way the Audi applies logic to the menu strategy to the scatter-gun approach of many others, and you can see that plenty of thought has gone into this stuff.

Also, it goes without saying, of course, that there are multiple charging points as well as plenty of connectivity with good wireless connections available. That includes wireless phone changing.

The front seats are sporty but not too firm, even if they do give you a bit of a squeeze thanks to high bolsters and lots of contouring. The rear seat is likewise firm initially and is really best for two backsides thanks to the sculpting of the rear bench.

That said, it will accept a centre passenger, but that seat will be the last one occupied. Rear legroom – important in a car like this - is good, there’s enough room for your feet under the front seats and headroom, even in the allegedly racier looking Sportback, is ample if not huge.

The panoramic sunroof means there’s plenty of light to counter the dark interior colours, and the only real surprise is the amount of hard plastic on the upper part of the door trims, just below the glass. Given the acres of much plusher trim farther down the door, this seems a bit odd.

The other comment we’d make is that the SUV body simply makes more sense in terms of load carrying (569 litres plays 528) and makes more of the SUV’s claim to practicality.

The Sportback is also a bit of an acquired taste and while it’s not the first SUV-coupe mash-up we’ve seen, to many eyes, the combination never looks right. Coupe on stilts? Surely, not for everyone.

On that subject of practicality, the SQ8 bucks the trend in EVs by being able to tow up to 1800kg with a braked trailer. The factory towing pack is a $2180 option.

None of the Q8 variants are what you’d call remotely spartan, and even the entry-level Q8 50 gets air suspension, Audi’s 'Virtual Cockpit', 20-inch alloy wheels, LED headlights, ambient interior lighting, dual-zone climate control, driver’s seat memory function, a head-up display, digital radio and a 360-degree camera.

The Q8 55 builds on that with the Sportback body (which is not available on the 50 variant) an extra 50kW of power from its twin electric motors, 21-inch alloy wheels, sports front seats and four-zone climate-control. There’s also an electrically adjustable steering column (the 50 has manual adjustment).

What makes the SQ8 the flagship car, of course, is not just more equipment (though there is plenty of that) but rather the optimised driveline with its three electric motors and 370kW output.

Beyond that, you also get a panoramic sunroof, 22-inch alloys, matrix LED headlights, heated front seats and a Bang & Olufsen premium sound system with no less than 16 speakers including 3D loud-speakers.

And because choice equals luxury, the SQ8 can be had in either of the Q8’s body styles; the station-wagon SUV or the Sportback. Neither of which run to a third row of seats.

Option packs include the 22kW charger option at $6900 and the 'Sensory Pack' which gets you headlights capable of branded projections on to your garage wall, e-tron branded puddle lights, powered, soft-close doors, heated rear-outer seats, an interior ioniser and 'fragrancer', extra dashboard leather and manual rear-window sun-shades. Yours for an extra $9600.

And if the SQ8 doesn’t look menacing enough, there’s a black exterior package at $2300 that, um, adds extra blackness.

The one option you need to think about carefully is the virtual mirror package which, at $3500, replaces the conventional mirrors with cameras that show what’s behind on panels in the top corner of the front door trims. It takes a bit of acclimatisation and revision of muscle-memory and is definitely not for everybody.

The price hike over the $140,600 entry level car is a hefty $33,000 for the SUV variant ($173,600) and a neat 40-grand for the Sportback ($180,600).

The EQE 53 punches out huge power, with the standard car producing 460kW/950Nm from its dual electric motor set-up, or with the 'AMG Dynamic Plus Pack', producing even higher figures of 505kW/1000Nm.

Clearly, AMG’s electric vehicles will safely outrun their dramatic combustion predecessors. In fact, with the Plus Pack, the EQE 53 is capable of moving its bulk from 0-100km/h in just 3.2 seconds. Extreme for something carrying a whopping 90.6kWh of batteries under the floor.

Enhancements include torque-vectoring all-wheel drive, all-wheel steer, adaptive dampers, and the choice of standard performance brakes or a carbon ceramic package.

While many electric all-wheel-drive vehicles use a motor on each axle, the Audi electric 'Quattro' system here arguably goes one better with a total of three motors.

The front axle features the traditional single motor while the rear axle has two; effectively a motor on each rear wheel.

When they all chime in, they bestow the e-tron with a maximum of 370kW of power and an astonishing 973Nm of torque; more than enough to get the 2.6-tonne e-tron moving.

Enough, in fact to get the car from rest to 100km/h in a claimed 4.5 seconds and on to an electronically limited top speed of 210km/h.

A single-speed reduction transmission is fitted and drive is constantly sent to all four wheels via an electric version of Audi’s famed Quattro all-wheel-drive layout.

Suspension is by adaptive air springs and there’s adjustable (via the steering wheel paddles) regenerative braking.

Electric vehicles appear to have the same issues as their combustion counterparts, in that they still drop in efficiency the more powerful you make them. In the case of the EQE 53, this means an average WLTP-rated consumption number between 20.3kWh/100km and 23.2kWh/100km.

'Thirsty' for an EV, although it is on par with the Porsche Taycan and still below Audi’s e-tron S.

When it comes to charging the EQE 53 can charge at a rate of 11kW on the AC standard, or a whopping 170kW on DC - allowing 180km of range to be added every 15 minutes. It also has the convenient option of a 22kW AC charger, a welcome inclusion if you intend to charge your car often at public outlets.

Total range for the 90.6kWh battery is 513km on the WLTP cycle.

Moving this much weight at such velocities and for such distances requires a big battery. In fact, Audi claims the SQ8’s battery, at 114kWh is the biggest in the business.

But, again, it needs to be, especially with the claimed energy consumption of a hefty 28.8kWh per 100km for the SUV version and 28.0kWh per 100km for the slightly slipperier Sportback.

That gives a theoretical range of 417km for the SUV and 430 for the Sportback, both of which are numbers some potential buyers won’t consider sufficient.

But those same people should consider the fact that in a mix of winding country roads and some freeway running, we were able to beat those consumption claims, recording closer to 26 or 27kWh per 100km which, if nothing else, suggests the published range figures might be somewhat closer to reality than the EV (or any other segment of the car industry) market typically gets.

The standard charger runs at 11kW but on a 10-amp household socket, home charging will be limited to 7.2kW, although an optional 22kW charger ($6900) is also available from Audi.

The DC charging is the highlight, however, and the SQ8 can cope with charging speeds of up to 170kWh, meaning it can theoretically get from 10 per cent to 80 per cent charged in about 31 minutes on a commercial charging station with enough grunt.

The way the EQE 53 drives was deeply unexpected. Just looking at this massive sedan, I would have expected it to feel burdened by its batteries, and with its length and shape, cumbersome in the corners. That wasn’t the case at all.

The EQE 53 feels remarkably coherent from behind the wheel. The seating position works well to give a nice view of the road, the steering feels a tad artificial but still direct with some AMG magic having worked its way in.

What surprised me most is how agile it feels. Once you gather some speed and attack some corners, this car shrinks. Control is excellent thanks to the massive tyres, all-wheel drive system, and all-wheel steering. It sounds like a lot of complexity, but you don’t notice any of it. Each system does its part to allow you to simply point the car where you want it to go at pretty much any speed. It is very impressive.

The ride feels supple, too, thanks to adaptive dampers, but offers plenty of control. The speed is Tesla-style violent. Put your foot to the floor in Sport or Sport+ mode and you’re thrown to the back of your seat as the car enters a state of warp. AMG says there won’t be a 63 version of this car, and I can’t imagine why you could possibly need anything faster or more capable than this 53 version. 1000Nm of torque!

This overwhelming number perhaps makes it more impressive that it’s hard to extract a squeak from the tyres. Sure there’s torque-vectoring magic at play, but even at full acceleration they hold on for dear life.

It also makes a noise. AMG is very specific about what went into making the soundscape for the EQE because in the electric era its performance can be achieved silently, and the brand knows full well its badge usually comes hand-in-hand with aural drama.

I stuck it in the stock mode and varied my driving from 'Comfort' to 'Sport+.' The sound builds as the car gains speed, but it also interacts with your accelerator and brake inputs, as well as being one of few EVs with a specific noise for regenerative braking. It sounds… odd.

There’s certainly a kind of drama to it, and to me, it’s better to have it as a way of gaining some feedback from the car. But, its artificial nature and loudness became a little too much for sustained driving in Sport + mode. I found the best balance in the more regular ‘Sport’ mode, or even toned down to ‘Balanced’ which puts it in the background.

This leaves quite a void, though. While the sound is welcome, and the throttle alarming, there’s just something missing from the usually brash AMG badge promise.

As an EV, the EQE 53 has three regen modes quite distinct from one another. Mercedes says the choice to have just three modes is deliberate, as it didn’t want to dilute the personality of the car with an overwhelming choice of regen. The three modes include: basically no regen, moderate regen, and the full regen, essentially a single-pedal driving mode. I preferred the strongest setting for efficiency's sake (plus it brakes for you as you let off!).

The EQE 53 is surprising in so many areas, and much more engaging to drive than its exterior visage might suggest. I’m impressed.

Almost a thousand Newton-metres (not to mention 370kW) infers some pretty serious performance and so it is.

When you press down on the throttle pedal, there’s an instant and somewhat furious response from the driveline. And just as the Audi’s touchscreens have been calibrated to respond on a human scale, so too have the major driving controls.

That said, while there’s more acceleration on tap than most drivers will ever have experienced, the SQ8 doesn’t move forward with quite the irresistible force the bald numbers might suggest.

And that’s purely down to the thing weighing the wrong side of 2.6 tonnes. Sure, Audi claims 4.5 seconds and that seems fairly believable, but it’s not quite as ballistic as some other current EVs.

Still, that’s hardly its mission in life, anyway. Top speed, in the interests of thermal management, has been limited to an entirely understandable – not to mention adequate - 210km/h.

But one thing all that kerb mass has (arguably) done is make the suspension work properly. Speaking purely personally, until I’d sampled the SQ8 over a variety of bitumen joins, potholes of all sizes and even clattering level-crossings, I was yet to drive a passenger car on air suspension that worked as well as the brochure claimed.

Historically, air suspension has been okay on smooth roads and even sometimes bigger lumps and bumps. But it usually fell short of expectations on small amplitude, high frequency stuff that made the suspension judder and stutter. Not this Audi.

Even on the 'Dynamic' setting, the ride never falls beyond plush although you will notice a little more stiffness being dialled into it by the computer.

The best advice is to leave it in the 'Comfort' setting where there’s still lots of roll and pitch control, yet an even higher degree of suppleness that fundamentally refuses to be beaten by a lack of post-Covid road maintenance. And this from a car that rides on 22-inch wheels and tyres.

Perhaps compressed air doesn’t scale in a linear manner, making the addition of a couple of tonnes of sprung mass a positive, rather than a negative.

The other thing Audi has done well to maintain is that almost indefinable corporate steering response.

It’s kind of muted this time around in terms of its ability to talk to you, but there’s still an over-arching Audi-ness to it with an instant pointiness without the frenetic feel often associated with a quick ratio and sticky tyres.

Like any modern, high-end SUV, the Audi is dripping with safety gear, both passive and the latest active driver aids.

Autonomous Emergency Braking is included, of course, but goes a bit further with pedestrian and cyclist detection. There’s also adaptive cruise-control with a speed limiter and the Audi offers assistance rather than just a passive warning with traffic-jam assist, collision avoidance assist, turn assist, exit assist, intersection assist, rear-cross traffic assist and lane-change warning and assist.

There are also front and rear parking sensors combined with a 360-degree camera system which includes a kerb view function for tight parking spots.

Given the bulk of the e-tron, that might be a pretty handy addition. A tyre-pressure monitoring system is also a great standard feature.

The SQ8 hasn’t been locally crash-tested but has scored a maximum five stars in European testing.

What’s missing? Probably only a central airbag to prevent front-seat head clashes in the case of a side impact.

Mercedes-Benz in Australia currently offers a range-wide five-year and unlimited kilometre warranty, a standard which is spreading to other premium brands.

We don’t know what the service schedule or running costs will look like for the EQE range yet, but expect it to be most affordable when chosen with a multi-year prepaid service plan at the time of purchase. Check back closer to its launch time to see the full details.

Audi’s factory warranty is a good, but no longer remarkable five-year/unlimited warranty on most of the SQ8.

The exception is the battery which is covered by a six-year/160,000km warranty. Audi will also come to your home and connect the standard 10-amp charger and there’s an Origin Energy green power offer that comes with it.

Charging is taken care of for the first six years with a Chargefox subscription as well as Audi Connect. You’ll also get six years of free roadside assistance and the first six years of standard servicing are also included.

The SQ8 also makes good on the EV promise of less maintenance with service intervals every two years or 30,000km, whichever comes first.
