Citroen C5X vs Audi Q4 E-Tron

What's the difference?

This is a new take on the Citroen station wagon, and it’s an impressive one at that. It may not tick all the boxes, but it is a comfortable and practical car, with stunning design, decent equipment and a pretty agreeable price tag.

Now, just get that plug-in hybrid version in at a reasonable price please, Citroen.

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.

Citroen reckons the C5 X combines SUV, wagon and sedan design cues to make it a true crossover model. I reckon they’ve got a point, and while it’s certainly not as butch as some other crossover wagons out there, it’s not bashful, either.

I’m a massive fan of the assertive front end lighting design, the bold body lines that punctuate the bonnet and swoop backwards down the sides of the car, and the swooping roofline that dips away, almost like the iconic Citroen DS.

It’s quite a large car, too - at 4805mm long on a 2785mm wheelbase, it has a commanding presence, and it’s 1865mm wide (not including the side mirrors) and a rather sleek 1490mm tall. 

Of course it has some body cladding and black plastics to give that ‘rough and tumble’ appearance - and the rear features a couple of spoilers on the boot that help it cut through the air cleanly, and they look interesting as well.

Inside, there’s an almost-square steering wheel, which is interesting, and a pair of screens - a 12.0-inch touchscreen for your multimedia duties, and a 7.0-inch driver info screen. It looks and feels upmarket and pretty conventional in the cabin, so let’s see what the practicality is like.

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 Citroen C5 X is almost as big as a Subaru Outback, and similar in size to a Kia Stinger. So it ought to have a bit of family-friendliness packed in.

Starting at the back, there’s a 545-litre boot capacity, with the kick-action, electronically controlled tailgate that you can also use the keyfob to open. It is a low, wide, quite squared-off aperture, meaning loading bulky items in should be a breeze. Just note that the roofline does taper down towards the rear, so bigger things will need to be pushed towards the seat backrests.

Or, if you’re really acting like a delivery van, you can drop the rear seats down to allow 1640 litres of cargo capacity. There are boot-mounted releases to drop the seats down, and there’s a floor mat in the boot, under which is a space saver spare wheel.

Back seat occupants are decently catered for. I’m 182cm/6’0” tall and I managed to sit behind my own driving position with plenty of leg and foot room - however, the sunroof does create a bit of a hump in the ceiling that you might bump your head on, and those with big feet or small children might want to take note that the sills in the door openings are very tall. A child could easily trip over them if they were clambering in the back in a rush.

Children will be covered with a pair of ISOFIX child-seat anchor points in the window seats and three top-tether restraints, too. There are map pockets, door pockets with bottle holders, a pair of USB-C charge points and directional air vents, too.

However, it wouldn’t be a French car without some kind of quirky cup holder situation, and the back seat has none - there’s no flip-down armrest to speak of. But the seat is exceptionally cushy.

Front seat impressions are good - and cup holders are present. They’re big ones, too - large enough for a big cuppa or a bottle of water, even, And there are door pockets with bottle holsters as well.

There’s an opening centre armrest box with a USB-C charge point, and in front of the interestingly designed recessed gear selector and parking brake, there’s another storage spot with a wireless phone charger, too. Nice.

Seat comfort up front is very good, with lots of adjustability (eight-way electric for the driver, six-way electric for front passenger) and heated front seats as well.

Scoring a big tick from me is the fact there are physical dials and buttons for the air conditioning and ventilation controls. But they’re in that glossy black finish, which shows fingerprints so much that it makes you feel self-conscious of being a walking germ farm.

The big touchscreen multimedia system has a few buttons and knobs, too - though the menus on screen do take some getting used to. It is highly customisable, so if you bought one you’d set it and forget it, but on first impression I struggled to get to grips with some of the nuances of the menus.

It does, however, have wireless or wired Apple CarPlay and Android Auto (with the media-feed USB-C port under the controls) and it goes full screen, too, while leaving enough space for other crucial elements. The graphics are nice and high-definition, and the 360-degree camera display puts  the “surround” view units in Peugeot models to shame. 

There’s also a configurable driver info screen, and a crisp and lovely head-up display as well. 

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…

Yes it’s almost 2023, but the Citroen C5 X model launching right now isn’t bringing anything new or exciting to the table in terms of what’s powering it.

Instead, it runs a 1.6-litre turbo-petrol four-cylinder engine that is also used in other Citroen and Peugeot models. No hybrid tech, no electric version yet….  But Citroen has stated it is keen to bring a plug-in hybrid model to the market. Hopefully, it comes soon.

The petrol motor used here is the brand’s PureTech 180 with Stop & Start, and it’s good for 133kW of power at 5500rpm and 250Nm of torque at 1650rpm. This isn’t a small car, but it is relatively light, weighing in at 1439kg (tare mass). 

However, it has a pretty small engine with low outputs for this type of vehicle. For context, the 508 from Peugeot has 165kW and 300Nm.

The C5 X has a standard fit eight-speed automatic transmission, and despite some SUV pretences, it’s a two-wheel drive, with power sent to the ground via the front wheels only.

That much-anticipated plug-in hybrid (or PHEV) uses the same petrol engine but adds an 81kW electric motor to the mix, for a combined output of 168kW of power and 360Nm of torque. Grunty.

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.

If you see a brand-new Citroen C5 X in the showroom or on the street you’ll note that the sticker on the windscreen shows an official combined cycle figure of 6.0 litres per 100 kilometres. For a petrol engine, that’s impressive.

Now, whether you get near that will be determined by how you drive. Lots of city and urban driving could result in a higher figure - but it does have start-stop tech for the true traffic grind.

On the launch drive, which included a mix of different driving situations, I saw an on-display return of 8.5 litres per 100 on the trip computer.

Fuel tank capacity is 52 litres, meaning a driving range of 866km if you can achieve the official figure, or 611km if you average what I did on the launch drive.

Can’t wait for the plug-in hybrid version of this car; it has claimed efficiency one-fifth of the petrol version launching initially - yep, it sips a claimed 1.2L/100km… but of course that relies on you making sure you actually charge it up and use the 50km of EV driving range it is said to offer. We’ll cover it off in more detail when the vehicle launches locally, likely sometime in 2023.

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.

If comfort is your main priority when it comes to your new car, then the Citroen C5 X (or any Citroen, really) should suffice.

The brand says that comfort is one of its defining features - a pillar of why Citroen exists, if you will - and as the flagship model in the brand’s lineup, this should represent the ultimate in comfort. 

And it does. 

The seats - with triple-layer foam - play a big part. They’re wider than most seats and, while they don’t hold you in place like the buckets in a sports car, this isn’t a sports car. 

It also has acoustic glass front and rear to help make it feel more serene and ‘cocoon-like’ inside. There’s barely any wind noise, and just a touch of road roar over coarse-chip roads, but it’s far from noisy in the cabin.

Further, it glides along with relative comfort over bumpy sections of road, with the so-called Suspension with Progressive Hydraulic Cushioning all-but eliminating road surface intrusion into the cabin. 

The suspension has hydraulic cushions at the ends of the springs and dampers (but before the bump stops) that are designed to delete the little bumps in the road surface, while also helping lessen the impact of larger imperfections like potholes. And, with the launch being held in Sydney on yet another wet day, the suspension did a spectacular job. 

You can still feel the 19-inch wheels moving around a bit when you sink into a pockmark, but the way it feels from the driver’s seat is very good. I didn’t get to play passenger on this launch drive, but the seat of the pants vibe I got was that all occupants will be cosseted nicely. 

That tendency towards relaxed movement is reflected in the handling of the car, too. It’s not a corner carver. You can engage Sport mode - which adapts the powertrain (engine and transmission calibration and sensitivity) and also the steering weight, if you really want to.

On the engine - it is perky enough in Sport mode and can do the 0-100km/h sprint in 8.1 seconds, according to Citroen.

This powertrain should really be categorised in the ‘comforting’ rather than ‘compelling’ category. It’s not a bad engine - but you can feel the weight of the car is holding it back, and it particularly feels a bit sluggish from a standing start. I also noticed a bit of vibration through the car under full-throttle acceleration, too. 

But honestly, unless you were trying to duck through a gap in traffic, you’re not likely to spend much time with your foot pinned to the boards in this car. 

I love and admire that this isn’t a car designed to be sporty. It isn’t trying to be that. The PHEV version will be more of a driver’s tool, with an adaptive suspension system and more power and torque. But honestly, I’d be happy with the C5 X as it is, because it’s just a lovely car.

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.

Buy a Citroen and you get a five-year/unlimited-kilometre warranty, as well as five years roadside assist and a five-year capped price servicing plan.

The C5 X isn’t cheap to maintain, with the average service cost sitting at more than $560 - that’s based on service intervals of 12 months/15,000 kilometres. 

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.
