Audi Q4 E-Tron vs Audi Sq8 E-Tron

What's the difference?

Audi is famous for sticking doggedly to front-wheel drive and quattro AWD, but clearly, when it puts its mind to it, the few RWD machines it has produced over its 116 years have been exceptional.

While not as exciting as the R8 or as supersonic as the e-tron GT, the Q4 e-tron is an impressive machine. Thoroughly engineered and thoughtfully designed to be a friendly, refined, comfortable, safe and capable family SUV, it deserves to be on your shortlist.

With a couple of choice option packages, the base 45 seems remarkably complete, but there’s plenty to enjoy in the hot-shot 55 quattro as well. Either way, Audi seems to be on a winner.

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.

Whether talking about the SUV or Sportback, the Q4 e-tron is an excellent example of Audi’s recent design prowess.

Beautiful proportions, crisp surfaces, exquisite detailing and undeniable elegance are all present in spades. And the Sportback is a rare example of a graceful-looking coupe SUV, though it is not in the otherworldly Polestar 4’s league aesthetically.

However, where is the originality? You’d never know these are rear-motored and predominantly RWD vehicles. Yes, the Single Frame grille execution is amongst the best-yet from the brand, while the wheelarch ‘blisters’ are an (albeit questionable) homage to the seminal Ur-Quattro of the 1980s, but the Q4 e-tron could be any contemporary Audi SUV from the Q3 up. Its design is the opposite of daring.

Still, maybe the Q4 e-tron’s classy, relatable conservatism explains why the Brits made this car their second-best selling EV of 2024, representing everything that the number one Model Y is not.

Plus, with current global automotive interiors stalling behind over-illuminated and oversized screens full of greasy fingerprints, glitchy electronics and reflections of their frustrated operators, a bit of old-school Audi cabin presentation knowhow can only be a good thing, right?

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.

Unlike most of its German competitors (and the Volvo EX40), the Q4 e-tron is built on a dedicated EV platform known as MEB, and shared with other Volkswagen Group models, like the Skoda Enyaq and Volkswagen ID.4.

Consequently, the Audi feels a wee-bit narrow inside, as the MEB SUV family are on the smallish side for medium-sized SUVs. This is not a criticism, just an observation.

And there is no lack of interior space, either. Entry/egress is easy via large doors, there’s plenty of space for heads and shoulders and legroom is generous. All are an upshot of the EV-only platform.

Despite some obvious packaging links with the other VW MEB interiors, the dashboard is very Audi-esque in styling, layout, functionality and quality.

From the ‘Virtual Cockpit’ electronic instruments and crisp multimedia screen, to the feel of the buttons and logical, easy locations of the controls, the Q4 e-tron is completely and utterly on-brand. And that means high standards. Looks posh. Works well. Nice to touch. No bewildering endless screen-menu search and rescue frustration here.

Plus, the Audi is practical. We’ve already talked about ample room, but even the standard, non-sports seats cosseted and supported over a few hours of testing; different and unexpected levels of storage (including a nifty bottle holder ahead of the forward door jam – brilliant); superb ventilation and, especially in the Sportback 55 e-tron quattro sampled, a banging audio system, complete a suave and sophisticated interior experience.

Issues? No too many, really.

There is quite a lot of quality plastic material visible, which might offend some sensitive souls. There is some road-noise intrusion over coarse surfaces, perhaps reminding owners of the Q4 e-tron’s shared architecture; and rear vision in the Sportback is hampered by fat pillars and slim back glass.  

However, no spare wheel exists. Nada. Just the occasionally ineffective and always-infernal tyre inflation kit, that renders the tyre and kit useless afterwards and so makes for expensive replacements. And just because almost everybody else does it, this is not good enough for Australia.

The corollary of that is quite generous luggage capacity, with the Sportback’s 535 litres somehow beating the more-upright SUV’s 520L VDA capacity, though with the rear seatbacks folded that switches to 1460L and 1490L respectively. Both are gorgeously lush and quite practically shaped.

And what about the storage compartment up front?

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).

Unlike the Model Y, there's no storage up front. That space is instead reserved for auxiliaries and, in the 55 quattro versions, the second electric motor that drives the front axle for AWD.

In all versions, a permanently excited synchronous motor sits on the rear axle driving the rear wheels via a single-speed transmission.

Tipping the scales at 2145kg, the 45s produce 210kW of power, to offer a power-to-weight ratio of 98kW per tonne, while the 2235kg 55s’ 250kW output ups that to 112kW/tonne. Both Q4 e-trons deliver a healthy 545Nm of torque.

No slouch, the 45s manage the 0-100km/h sprint in a rapid 6.7s, while the 55 quattro’s extra motor chimes in when extra traction is required, shaving another 1.3s off that, for a 5.4s time. Top speed in both is limited to 180km/h.

Adding a bit more driver involvement, the 55s have variable ratio steering, while MacPherson-style struts up front and a four-link independent rear suspension setup out back help keep everything under control.

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.

Built on a 400V architecture, the Q4 e-tron uses an 82kWh Lithium-ion battery pack, offering a useable capacity of 77kWh. It only charges to 80 per cent full to help preserve battery life.

Now, driving most of the available versions over a 200km launch route from Adelaide airport to wine country, we averaged between 17.5 and 19.5kWh/100km, with the lighter RWDs obviously being the more economical of the drivetrains.

In ascending order, the official combined average figures are 16.9kWh/100km (Sportback 45), 17.4kWh/100km (45 SUV), 17.5kWh/100km (Sportback 55 quattro) and 18.1kWh/100km (55 quattro SUV).

Despite weighing about the same, the Sportback uses around 0.5kWh/100km less electricity than the SUV version, due to better aerodynamics.

That translates to about 15km of extra distance, with the Sportback 45 going the furthest, delivering a WLTP range of 540km. That’s followed by the 45 SUV, Sportback 55 quattro and 55 quattro SUV with 524km, 503km and 488km respectively.

To aid with recharging, the driver has three modes of battery energy recuperation via steering-wheel paddle shifters.

Plugged in at home, the battery needs about 40 hours to completely recharge, or over 12 hours using an optional 7kWh Wallbox. Maximum AC charging capacity is 11kW.

With a maximum of between 135kW (RWD) and 175kW (AWD) of DC charging capacity, however, 10-80 per cent charge using a 50kW DC public charger needs fewer than 70 minutes, or just 40 minutes if you find a 100kW station.

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.

Audi might be late to the affordable electric SUV party, but it’s certainly been worth the wait from behind the wheel, because the Q4 e-tron drives exactly how you would expect an Audi to.

The 45 in either body shape has ample oomph, as its impressive 6.7s 0-100km/h times prove, providing a decent amount of instant speed the moment you put your foot down. This is a smooth, strong and muscular performer.

The steering is nicely modulated and precise, for easy, flowing handling, even when the speed is taken up a few notches. Note that while it may seem a little light, it can be configured for a more dynamic feel.

However, slightly stronger single pedal braking would be appreciated. The Audi EV’s brakes do a great job stopping the car, but they do feel a bit on/off at first. Maybe even a bit wooden.

All the Q4 e-trons we drove on the launch around the Adelaide hills rode on steel springs. That said, and to our surprise, the suspension is more than comfortable enough, soaking up many of the bumps we encountered without breaking a sweat.

Plus, except on coarse bitumen, there's not much of any type of noise coming through inside the cabin. These are agreeably comfortable and refined cruisers.

Meanwhile, the 55 quattro version is a slightly different proposition, with measurably stronger acceleration across the board and more eager throttle response. Actually, even on bone-dry roads at the height of summer, there’s almost too much torque coursing through the axles, so just be wary of this EV’s considerable power.

Still, the twin-motor Audi feels like a relaxed yet brawny grand touring SUV, with plenty in reserve for fast overtaking and quick getaways. Even the RWD model provides exceptional roadholding and control, but that extra AWD grip when things become a bit slippery would certainly be a bonus.

Plus, kudos to the Germans for delivering user-friendly driver assist safety systems. Nuanced and largely unobtrusive, they keep you safe without driving you to distraction. China and Polestar in particular, are you listening?

On the flip side, you do feel the extra weight of the second electric motor (about 100kg more), and so it doesn't quite have the agility and alacrity of the standard 45 RWD machine.

Indeed, there isn’t quite the athleticism or connection of driver-focused alternatives (like BMW), but the Q4 e-tron rarely puts a foot wrong, either.

Impressively capable and dynamic, Audi’s more-affordable electric SUV has been worth the wait.

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.

Audi’s warranty remains the same as before, at five years with unlimited kilometres, with the battery covered for eight years or 160,000km. Six years of roadside assistance is also included.

Service intervals are every two years or 30,000km. Nothing special here nowadays.

But the Q4 e-tron owner can buy a six-year service plan for a total of $2050, while gaining 12 months of free electricity at Chargefox stations. They can also purchase a JET Charge home installation charger from $800.

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.
