Citroen C3 vs Audi S5

What's the difference?

The Citroen C3’s plus column contains some big ticket items like a solid standard equipment list, design flair, generous interior space, an eager engine, good safety and a comfy suspension. However, the minus side of the ledger isn’t exactly empty, with entries like steep price, marginal perceived quality, poor cabin storage, sub-par refinement, okay economy, and high ownership costs. 

But there’s no doubt this car delivers a different, adventurous take on the city-sized hatch, and for you, that alone may count for more than any of those things. 

The Audi A5 remains a convincing option in the premium mid-size sedan category, even with the near-$10K price increase over its equivalent grade A4 predecessor.

Even in its base spec, it’s a lovely thing to drive and adds enough new kit to be a reasonable option when it comes to value. In terms of tech usability, it stands out from rivals. Practicality is still king for Audi.

But for the heart-over-head types, the S5 is fast and fun while remaining a comfortable cruiser and the price is decent. On a personal note, a six-cylinder wagon? That's a big yes from me.

For the time it’s available, it’s hard to go past the value on offer in the S5 Edition One. Getting an AWD V6 with that kind of capability for under $100K is something that's sure to tempt buyers. If it doesn’t, we need to take a good look at ourselves.

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

If Citroen is known for anything it’s daring, innovative design. From the idiosyncratic 2CV, via the sleek DS, to the ultra-cool SM, and angular BX, Citroen boasts a 100-plus year back-catalogue of stunning automotive breakthroughs.

And true to form, the C3 sits left-of-centre with a determined, almost angry expression defined by chrome borders extending from its signature ‘double chevron’ logo above the grille.

A mix of carefully radiused curves, soft organic shapes and whimsical decoration define the rest of this SUV-ish hatch. Rounded rectangles and squares (squircles?) are a recurring theme, forming part of a dent-resistant panel along the car’s flanks and embossed into the door cards inside.

Our white test example sported a (no-cost) contrast red roof colour, the same shade picking out details like the front fog light surrounds, exterior mirror caps and side scuff panels. 

The interior is less bold with a multi-tone grey colour palette broken up by light green contrast stitching on the seats, as well as piano black finish on the centre console and satin chrome highlights around the air vents, instrument panel and door handles.

Plus, the squircle still makes its presence felt in everything from the directional air vents to the speaker grilles and sections of the dash.

Functionality and ergonomics are good with sensible touches like a physical knob for audio volume control (big tick) as well as easy-to-navigate controls for audio, phone and more on the steering wheel.

An unexpected highlight, and regular talking point with people in the car during my week with it, is what Citroen calls ‘Luggage-inspired’ front interior door handles. 

Check out the interior photos. The straps look amazing, are easy to use, and remind me of the handle on my mum’s circa-1965 Olympia portable typewriter.  

The A5 incorporates Audi’s new design language in a way that makes the 2026 model stand out from Audi’s older offerings, but we won’t know how well it works in the family until more new-gen Audi cars arrive.

For now, the A5 is a generally handsome car. It very much looks like an Audi from the front, even a recent A4 if you only very quickly glanced.

The aforementioned S line styling does plenty in making even the base Audi A5 look like a properly luxe thing. There were a few double-checks at the launch to make sure drivers were getting into the right cars.

Fortunately the new car’s designers refrained from busying up the car with trim, the only big features being the side vents at the front.

But even in Avant form the S5 looks athletic, quad-exhausts in the lower bar and the angular rear bodywork moving away from the previously softer, more rounded look Audi had gone with before.

Inside, the changes are arguably more obvious. The A5 is now much more ‘screeny’ than before, especially if optioned with the passenger-side touchscreen.

It’s still decidedly Audi in its layout and design, with geometric shapes on the steering wheel, screen housing, door cards and even on the gear shifter, which is no longer the more traditional handle-type.

At a fraction under 4.0m long, just over 1.8m wide, and close to 1.5m tall, the C3 is a small hatch that, in terms of practicality, does well in some areas and could do better in others.

On the plus side, there’s plenty of space for the driver and front seat passenger, and rear room is surprisingly generous. Sitting behind the driver’s seat, set for my 183cm position, I had more than adequate head, leg and knee room.

Three full-size adults across the rear is a short-journey proposition only, but a trio of up to mid-teenage kids will be fine.

The space-efficiency carries over to the boot, with 300 litres of volume available (below the parcel shelf) with the 60/40 split-folding rear seat upright. But beyond that number, the space has been carefully sculpted to maximise usability.

We managed to fit our three-piece (36L, 95L, 124L) luggage set in there, with a small cheat of removing the divider, and could swap them out for the bulky CarsGuide pram, with room to spare. Fold the rear backrest down and available space increases to an impressive 922 litres.

The downside is storage and concessions to comfort elsewhere in the car. As in, a lack of them.

For a start, the dual cupholders in the front centre console confirm the French’s affection for Espresso. You’ll struggle to locate an average size take-away coffee cup in one of those dainty receptacles.

The front door bins are long but relatively narrow, and lack a designated spot to hold bottles upright, so I found myself laying drink bottles horizontally along them, which is awkward.

Plus, there’s no lidded storage box between the front seats, so no centre armrest, either. Rather an open tray behind the handbrake lever.

The glove box is modest, there’s a small open cubby below the central multimedia screen that isn’t big enough to hold a phone, there’s just one USB-A port for connectivity/power and a single 12V outlet.

No fold-down centre armrest in the rear, either. There are map pockets on the front seat backs, a single (again, small) cupholder at the end of the front centre console for back-seaters to share, and while rear door pockets are welcome, they’re petite.

Yes, the boot is commodious, but it lacks tie-down anchors to secure loose loads, and the flimsy carpet in there is prone to moving around.

On a more positive note, the spare is a 15-inch space-saver, which is streets ahead of the all-too common inflator/repair kit.

…and that gear selector is a bit indicative of the new A5’s interior. It’s now more of a switch that requires a little more attention than the traditional shifter, just like the way the more screen-focused interior requires a little more of your eyeball time than physical buttons.

Don’t get me wrong, as far as screens in modern cars go, Audi seems to have made it as easy as possible to use the new-gen software in the A5. The menus are clear, there are good shortcuts and there’s no lag… but buttons are always better when your focus needs to be on the road.

Fortunately the driver display is nice and clear, it’s a good update on Audi’s ‘Virtual Cockpit’ and you can set it to display important information without looking too busy.

Ergonomically, the way the central screen is angled towards the driver, the centre console layout and the small control panel on the door for lights, mirrors and the like all seem to be well considered and mean you don’t have to awkwardly reach for anything.

There are a few quirks specific to the A5 and S5, one being that if you opt for the panoramic sunroof, it comes with a transparency switch rather than a physical cover, so it doesn’t do much to keep the light out.

It’s also good to note that the passenger screen - again, if optioned - turns to privacy mode when playing media so as to not distract the driver. Pretty handy!

Behind the front row, a regular-sized adult should have enough room to sit comfortably for a decent amount of time without feeling cramped. The light through the sunroof comes in handy here.

Behind that is a 445L boot in Sedan form, or 1299L with the rear seats folded down. As an Avant, the space increases to 448L and 1396L respectively.

The new Audi A5 range starts from $79,900 before on-road costs for the standard A5 Sedan, though the rest of the models available at launch are all S5 variants. A more powerful A5 with 200kW and quattro all-wheel drive will come later, as well as a 270kW plug-in hybrid A5 quattro variant.

For now, the sole A5 in the line-up is well equipped for the price, coming with standard 19-inch alloy wheels, matrix LED headlights with adjustable lighting signatures, keyless entry and digital key via Audi’s app, electric bootlid (or tailgate, given its liftback style) and S line styling as standard.

Interior features include sports seats in real and synthetic leather, heated and electrically adjustable up front, leather steering wheel, tri-zone climate control, a 14.5-inch OLED multimedia touchscreen and 11.9-inch driver display, wireless phone charging as well as wireless Android Auto and Apple CarPlay.

The A5 can be optioned with a Style pack for $3000 which adds 20-inch wheels, tinted glass and black exterior trim. There’s also a Premium pack for $3769 which adds a head-up display, high-power USB ports, a Bang & Olufsen sound system, ambient lighting and front door acoustic window glazing.

The other key variants in the line-up from launch are the S5 Sedan and S5 Avant, coming in at $114,900 and $117,900 respectively. Aside from the more advanced drivetrains, the S5s also gain plenty more features over the A5 including 20-inch Audi Sport alloy wheels, selectable OLED rear lights, tinted windows and more paint colour options.

Inside, Nappa leather-upholstered seats gain cooling and massage functions up front, the steering wheel is heated, and there’s ambient lighting with a ‘dynamic interaction light strip’ that changes colour based on vehicle functions like indicating or changing temperatures.

There’s also a head-up display, high-power USB outlets, a Bang & Olufsen sound system and, perhaps most notably, a 10.9-inch touchscreen for the front passenger as standard. It’s a $1500 option in the A5.

Audi also has a launch variant of the S5, the Edition One, which comes at a lower price and a trim spec closer to the A5, but with the S5’s performance. It has non-adjustable sport suspension, for example, and to score much of the main S5’s kit requires cost-options or option packs.

But the prices are tempting, just $99,900 for the S5 Edition One Sedan or $102,900 for the Avant, $15,000 less than their same-power siblings. For an extra $6000, you can add a head-up display, high-power USB ports and the Bang & Olufsen sound system to the Edition One.

Comparing the entry A5 to the recent entry-level A4, the new A5 wears a price increase of $8000 (the ageing A4 is $71,900), but has more power and a much more modern interior. On price alone it seems a steep jump, but the value is still there compared to rivals. A Mercedes C200 currently starts from $89,900, while a BMW 330i is $92,900.

The Citroen C3 is powered by a small-capacity (1.2-litre), turbo-petrol, three-cylinder engine, driving the front wheels through a six-speed automatic transmission. 

This little unit punches well above its weight thanks to tech like direct injection, and dual variable valve timing to enhance pulling power. The lightweight (all-alloy) unit produces 81kW of power at 5500rpm and a substantial 205Nm of torque at just 1500rpm.

The Audi A5 is powered by a four-cylinder turbo-petrol engine which powers the front wheels via a seven-speed dual-clutch automatic transmission. It makes 150kW of power and 340Nm of torque, and should, Audi says, propel the A5 to 100km/h in 7.8 seconds before (eventually) reaching a top speed of 248km/h.

The S5, in all its variants, is powered by a 3.0-litre turbo-petrol V6 which is assisted by a mild hybrid system. It produces 270kW and 550Nm, sending that to all four wheels via a similar seven-speed dual-clutch.

The S5 is much quicker as a result - 100km/h comes along in just 4.5 seconds according to Audi, before reaching a 250km/h top speed.

Citroen’s official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle is 5.2L/100km, the 1.2-litre three-cylinder emitting a modest 118g/km of CO2 in the process.

Our time with the car included mainly city and suburban trips, with some freeway running thrown in, and the result was a (dash-indicated) average of 8.0L/100km. Not exactly miserly, and points to the turbo triple having to work pretty hard to keep up around town.

Minimum fuel recommendation is the relatively pricey 95 RON premium unleaded, but you’ll need just 45 litres of it to fill the tank. Using the official consumption figure, that translates to a range of 865km, dropping to around 560km using our real-world number.

Audi claims the A5 uses 6.9 litres of fuel per 100km, which should theoretically deplete the 56-litre fuel tank after 811km of driving. We couldn’t test this on the launch, but reaching claimed fuel efficiency figures remains an elusive challenge.

The S5, according to Audi, comes with an impressive 7.1L/100km figure in Sedan form, or 7.2L/100km as an Avant. That’s 788km and 777km of theoretical driving range if you’re up for a challenge.

The C3’s compact footprint and relatively light weight (1090kg) make it an urban-friendly option and outputs from the 1.2-litre turbo-petrol engine are exceptional.

Maximum torque of 205 Nm is plenty of pulling power from such a tiny unit, and with that number arriving at just 1500rpm it should be ideally suited to stop-start traffic. 

And yes, with enthusiast use of the right pedal the C3 gets up and goes pretty well, but refinement isn’t its strongest suit. 

The throttle can be jumpy unless you’re super smooth with it, the three-cylinder engine’s typically coarse note makes its presence felt under load, and the brakes need to be dealt with gently to avoid an overly aggressive stop.

Sure, familiarity and practice will help you get in tune with the car but it’s not a smooth ‘plug-and-play’ drive like the majority of its competitors.

That said, in true Citroen fashion, steering feel is good, the front seats are as comfortable as they are supportive, while the suspension manages to blend plush compliance with excellent dynamic response. Another Citroen hallmark.

The six-speed auto shifts smoothly, with a press of the Sport button encouraging it to shift up later and down earlier for a more urgent response. But the zig-zag (my term, not Citroen’s) shift pattern makes for an awkward shuffle between D, N and R when parking. No doubt you’d get used to it, but I’m not a fan.

Speaking of parking, the C3's diminutive size makes it easy to slot into even tight spots, the standard front and rear proximity sensors, as well as a decent resolution reversing camera helping out, too.

One of the first press cars I ever drove as an even younger lad than I am now was the circa-2017 Audi S4.

Without the perspective of all the many, many cars I've since driven, that S4 blew my mind a little bit with its combination of capability and refinement.

Now, with the context of most of the cars available to the Australian buyer in mind, it’s reassuring to get into this new generation and find that the mid-size Audi torch has been gracefully passed on.

Audi says the new generation, sitting on its new platform, has more focus on balanced driving dynamics, steering precision and steering feel. Without sacrificing comfort, Audi wants the A5 to be a sharper driver’s car.

It might not gel with the Euro tradition of a rear-drive executive sedan given the base A5 is front-wheel drive - the brand of course focusing on its quattro all-wheel drive system - but the A5 is decidedly agile for its size. 

Compared to the S5 especially, as the A5’S 1770kg plays the S5’s 2025kg in Sedan form (2040kg as an Avant). It’s a noticeable weight difference, and it makes the A5 more playful without getting properly ragged.

It also rides on smaller 19-inch wheels and would overall probably make for the better daily driver. Even without the all-wheel-drive traction and extra power the S5 offers, the A5 makes a good case for properly plush commuting. Its 150kW isn’t lacking by any means, and that 340Nm does plenty to help when overtaking.

Its suspension feels well damped, keeping the road’s imperfections out of the cabin without numbing the ride and leaving you without feedback. The steering is similarly direct without being too heavy, making the A5 feel athletic for its size.

But for all the A5’s strengths, there is something undeniable about a six-cylinder European sedan (or wagon). The S5 is heavier, sure, and therefore not as naturally nimble, but it makes up for it. And it’s not just the extra power and mild-hybrid assistance.

It’s a great highway cruiser for a start, but it also adds the confidence of all-wheel drive to a trip, which proved extremely useful on the very rainy winter day we tested it. It holds up well on rough surfaces despite the bigger wheels and extra heft, plus it doesn’t feel out of hand when cornering fast, rolling into a predictable understeer rather than quickly losing traction.

But if you’re in any way conscious of your budget, consider the Edition One. It doesn’t lack any of the key things that make the S5 great, and you get to pocket enough money to buy a second used car.

The A5 and its S5 variants share the same safety features, with the full suite of Audi’s more-than 30 safety and driver assistance systems standard across the line-up.

Physically, the A5 has nine airbags and has been crash-tested by Euro NCAP, the firm awarding it five stars. There's no local ANCAP score as yet.

Some of the key safety features in the A5 and S5 models include a driver attention alert, seatbelt reminders, tyre pressure indicator, adaptive cruise control, lane departure warnings and lane assist, front braking assist, front and rear cross-traffic alert, speed limit sign recognition, surround view cameras and park assist with front and rear parking sensors.

There are also ISOFIX points for fitting child seats to the rear outboard seats.

Citroen covers the C3 with a five year/unlimited km warranty, which is cost-of-entry now in the mainstream market, and roadside assistance is included for the duration.

Service is scheduled for 12 month/15,000km intervals, with costs capped for the first five workshop visits. The average annual figure over that period is $505, which is way more than double the $205 you’ll pay annually for servicing a Toyota Yaris ZR Hybrid. Sacre bleu!

Audi’s five-year/unlimited kilometre warranty is starting to fall behind the industry standard, though is about normal for a premium brand. On top of this, customers can opt to purchase extra years of warranty up to a maximum nine years which costs $3590.

Audi does also offer 12 years of bodywork manufacturing warranty against corrosion or perforation. There’s also five years of Audi roadside assistance.

Servicing intervals for the A5 come in at every 15,000km or 12 months, with customers able to purchase fixed-price servicing plans at a discount compared to paying per service.

A five-year servicing pack for the A5 Sedan is $3360, and for the S5 it’s priced at $3540.
