Audi Q3 vs Audi Q4 E-Tron

What's the difference?

So is this new Q3 good enough to remain Audi’s number one choice? In a word, yes.

Audi has resisted the temptation that some brands fall into by making too many changes to a proven sales performer. This new Q3 isn’t radically different from the old Q3, but it has improved in almost every way.

It isn’t different enough to widely expand its appeal to a new wave of customers, but there’s no reason it won’t remain Audi’s most popular choice for the foreseeable future.

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.

The brief to the designers was seemingly pretty simple - don’t mess with a good thing.

According to the company, they want it to be recognisable as an Audi from 100m away, but at the same time, it makes sense not to make any radical changes to a design that is clearly a hit with buyers.

There’s still a new grille, which is slightly larger, while the daytime running lights (DRLs) are now mounted high, on the top corners of the front fascia.

Audi prides itself on its lights and the Q3 features multi-segment DRLS, with dynamic light effects, plus the rear badge lights up red with the tail-lights are turned on.

Digital matrix LEDs are available as an option on the quattro grades, which is a first for such a small Audi. While based on the technology already deployed in the bigger, more expensive Audi models, this is an updated system with micro LED matrix capabilities that are better able to light up the road ahead without blinding cars ahead or oncoming.

One very noticeable element to the design of this new Q3 is the size - which hasn’t really changed. Audi has resisted the temptation that so many brands have to upsize a compact model and has instead retained the same size that buyers clearly find appealing. It is slightly longer, approximately 4cm, but is still unmistakably a Q3 in looks and size.

Inside the Q3 is a different story, with the designers clearly empowered to create more change. The elements remain similar, but there have been more dramatic changes compared to the exterior to keep the Q3 looking contemporary and luxurious.

For example, there are still two large screens, just like the old model, but the virtual cockpit and multimedia screen are integrated into the dashboard together and more prominently, moving higher up the centre fascia.

It works well, as the interior looks and feels premium, and very much an Audi, albeit on a smaller scale.

To cap it off there are four interior colour packages to choose from, plus four different choices for the inlays, including two real wood options and an aluminium trim.

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?

The biggest change to the interior is the technology, with a new multimedia interface with new, larger tiles as well as new ‘Control Unit’ for the key driving functions.

The ‘Virtual Cockpit’ display is much simpler, with a nice, clean look, plus the option to have the satellite image on the screen, whether you’re in navigation or not. The multimedia screen is a good size (12.8 inches) and the menus are easy to navigate. The decision not to have physical controls for the climate control is disappointing, but thankfully there is a volume/on-off dial for the sound system.

The most notable difference is the so-called ‘control unit’ that integrates the indicators, wipers and gear selector on a single ‘bar’ mounted to the steering column. It’s another example of modern cars reinventing something we’ve all become accustomed to, but after a day of driving it quickly becomes second nature to adapt to the slightly different controls.

While it may be the same size, Audi has managed to find more room inside, particularly the rear, by redesigning the door pockets and sculpting out the seat backs. It’s still not the roomiest cabin, but the rear seats will be fine for younger families, couples and singles.

Another plus is the 40:20:40 split/fold rear seats for maximum practicality and adaptability, while all three have child seat anchor points (although if you do have three small children, I wouldn’t be recommending an SUV this size). 

As for the boot, because Audi only measures to the top of the seats, it measures 488L in both the SUV and Sportback variants, so you’re not missing out on day-to-day practicality with the sportier-looking roof. However, if you drop the rear seats the cargo capacity expands to 1386L in the SUV but only 1289L in the Sportback.

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?

The Q4 e-tron is available in two body shapes – a handsome if quite conservative wagon SUV style, as well as a sleeker coupe-SUV derivative that Audi calls Sportback.

The latter is expected to be the slightly more popular of the two designs, despite costing about $1600 more.

Obviously slotting in between the smaller Q3 and larger Q5, the Q4 e-tron almost shadows the latter size wise, and is available in either 45 RWD or 55 quattro all-wheel drive (AWD) guises.

Since both share the same, largish (82kWh) battery, Audi reckons most buyers will choose the 45, especially as its pricing in either body style slips under the Australian Federal Government’s Luxury Car Tax (LCT) threshold.

Kicking off from $84,900 before on-road costs, the base grade includes a full suite of safety tech such as full stop/go adaptive cruise control, an electronic instrument display, heated front seats, three-zone climate control, a gesture-controlled powered tailgate and 19-inch alloy wheels.

These come on top of the LED headlights, an 11.6-inch touchscreen, full wireless multimedia connectivity, a premium audio system, electric driver’s seat adjustment, navigation, folding/heated/kerb-side-view mirrors, roof rails and automatic parking.

From the Sportback 45 and up, the S-Line package is standard, bringing with it 20-inch alloys.

All the essentials then.

But, on the base 45s, be prepared to spend extra for luxuries like bolstered “sports” seats, a head-up display, a powered front passenger seat, driver’s side memory settings, a 360-degree camera instead of the regular rear-only view and privacy glass.

The 55 quattro grades from $105,900 include most of these, along with an extra electric motor for AWD and considerably more muscle, as well as variable-ratio steering, Matrix LED headlights, dynamic indicators, extra lane-assist intervention and the aforementioned S-Line trim shod with 20-inch alloys.

Now, against the remodelled Tesla Model Y Juniper, the Audi costs considerably more, but it is also a more upmarket (and less conspicuous) luxury brand that prioritises quality.

The iX1, iX2, EQA and EX40 cost around the same as the Q4 e-tron, but aren’t quite as large, offer smaller batteries (Volvo-aside), are based on other internal combustion engine (ICE) models compared to the Audi’s ground-up dedicated-EV architecture and, except for the BMWs, are getting somewhat long in the tooth.

Conversely, fresh designs, bespoke electric platforms and bigger batteries set the larger yet less-expensive Polestar 4 as well as the more-compact yet loaded Genesis GV60 apart against the Audi’s aforementioned competitors, but neither challenger brand is as established as all the others. Finally, Lexus’ UX300e is too compact while the larger RZ450e has priced itself out of contention here.

So, why the delay getting the Q4 e-tron to Australia? Especially when the brand has offered the bigger and much-more expensive Q8 e-tron SUV since the beginning of this decade?

Initially, demand in Europe was through the roof and supply could not keep up. Then Audi elected to wait for an update that debuted globally in September 2023, ushering in a raft of changes, to make its most important EV ever more competitive in a wildly shifting market.

These include efficiency gains leading to more range thanks to an upgraded motor and battery, stronger performance, faster charging, retuned steering, comfier suspension and improved safety spec.

Not that you’d be able to spot the differences comparing new Q4 e-tron with old. Nor even against sibling SUVs…

As mentioned above, there are three powertrains to choose from initially, with talk of a plug-in hybrid and hi-po RS Q3 just that (talk) for now.

The entry-level SUV and Sportback get a new 1.5-litre four-cylinder mild-hybrid, turbocharged petrol engine, which makes 110kW/250Nm and sends all that performance to the road via the front wheels through a seven-speed, dual-clutch automatic transmission.

Next up is the TFSI 150kW quattro, which is a bigger 2.0L turbo-petrol four-cylinder, producing (you guessed it) 150kW and 320Nm. It also has a seven-speed dual clutch but also unsurprisingly has a quattro, aka all-wheel drive.

Finally there’s the TFSI 195kW quattro, which has the same engine but tuned to make 195kW and 400Nm, also with the seven-speed, dual-clutch auto and all-wheel drive.

This is naturally the quickest Q3, at least until the RS Q3 arrives, taking just 5.7 seconds to accelerate 0-100km/h, compared to 9.1 seconds for the 110kW and 7.1 seconds for the 150kW.

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 it may only be a mild hybrid, Audi has done its best to make the TFSI 110kW as fuel efficient as possible. To that end, in addition to the hybrid help this new 1.5-litre engine also features cylinder-on-demand.

The result is a claimed combined cycle fuel use figure of 5.7L/100km for the entry-level model.

Naturally the more powerful engines require more petrol. The 150kW models are rated at 7.3L/100km, while the 195kW has a claimed 8.1L/100km.

It’s worth noting that all three engines require a minimum 95 RON ‘premium’ fuel, which will only add to the cost at the pump in these times of high prices.

The 110KW/150kW models are fitted with a 55-litre fuel tank, while there is a bigger 60-litre tank for 195kW. That means theoretical driving ranges of approximately 960km for the 110kW models and just over 740km for the 150kW and 195kW offerings.

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.

While it may not be an RS model or a more dynamic sedan, part of the price premium you pay for an Audi is a more polished driving experience.

With that in mind, what Audi calls ‘Progressive steering’ (which is a variable ratio steering rack) is now standard across the range. This decision was driven by a desire to make the Q3 feel ‘more hatch-like’ to drive, being more responsive to driver inputs.

It certainly felt quite nice to drive at the launch, where we drove across a wide variety of conditions, including long stretches on winding mountain roads. The 110kW Launch Edition was enjoyable to drive in these conditions, even if the other two options offer a sportier driving experience with their extra power and all-wheel drive.

It should be noted again, we only drove Q3s fitted with adaptive dampers as those are included on the Launch Edition, so we can’t tell you how the true entry-level TFSI 110kW model rides and handles.

One minor concern was there were some rattles in one of the three cars we tested, centred around the dashboard and front doors. It’s notable because we have experienced similar potential build-quality issues with Volkswagen and Skoda products recently. This raises some questions about an area Volkswagen Group products have traditionally excelled in.

Having said that, it was only a problem in one of the three cars we drove, so it could be an isolated incident. But it’s something we will have to keep an eye and ear open to in future test drives.

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.

Tested back in 2021, the Q4 e-tron managed a five-star ANCAP crash-test rating, and possesses most of the driver-assist safety systems expected nowadays in this class of car.

This includes Autonomous Emergency Braking (AEB, dubbed Audi Pre-Sense in corporate-speak), lane departure warning/assist, rear cross-traffic alert, blind-spot warning, on-coming traffic turn-and-swerve collision avoidance, exiting-vehicle alert tech, adaptive cruise control (with active lane assist in the 55s), driver attention monitor, tyre pressure indicators, 360-degree cameras, and light and rain sensors.

AEB operating parameters vary. Car to car, it’s between 5km/h and 250km/h. For pedestrian/cyclist/back-over, it’s from 5km/h to 85km/h. And the lane support systems work between 60km/h and 250km/h.

All outboard occupants also enjoy full airbag coverage – front, front side/centre, and full-length curtain airbags.

A trio of child-seat anchorage points are fitted across the back seat, along with ISOFIX child-seat anchorages in the front passenger seat and two in the rear outboard positions.

The Q3 is covered by Audi Australia’s standard five-year/unlimited kilometre warranty. This includes five years of roadside assistance too.

There is a standard five-year servicing plan for $3300, which is the same as the outgoing model, with servicing required every 12 months or 15,000km, whichever comes first.

Audi has an expansive, nationwide dealer network befitting its place as an established sales leader in the premium space.

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.
