Audi RS6 vs Citroen C3 Aircross

What's the difference?

To me at least, the RS6 is pretty much the ultimate fast and practical car. One which is just as comfortable plodding around town as it is tearing it up on the track. Keep in mind, too, this may be one of your last chances to have a car which looks like this, equipped with a V8 engine. So, have I convinced you? Would you consider one of these over a performance SUV? Tell us what you think in the comments below.

It's a good car, no question. Individuality is key to Citroen's brand appeal and you get that, too. A comfortable cabin, plush ride and hot damn, it's way too expensive, which is a crying shame. You could argue - as Citroen's product planners probably have - that it doesn't help to offer one in the mid-$20K mark because it won't make much money because so few people will buy it. Drop it at a premium, only lose a few opportunistic buyers but make more money per unit with committed fans? Why not, I guess?

Like most French cars, I'm glad it exists for weird French car fans like me to consider.

At a distance the RS6 is just an unassuming station wagon, but the closer you get, the more apparent it becomes how mean it is. It’s wide, it’s chiselled, it’s not just good looking, it’s iconically Audi.

The stance is so wide, its ride height so low, and its wheels are so massive that any keen eye will be able to spot where the difference is between this and any old family hauler.

Wagons may not be trendy, but there’s something undeniably cool about having the hauling capacity of an SUV at the ride height of a sedan.

Of course, if you want to look even more svelte and don’t need the boot space, the RS7 is always lurking around at a slight price premium.

Inside, the RS6 has all the modern amenities of the Audi range. Expect the usual sharp screens, lovely sports seats, and a tasteful application of textures throughout.

There’s a blend of carbon-look finishes, chrome, leather and gloss black. Perhaps a little too much gloss black to keep clean, but the aesthetic is suitably upmarket. 

You can go to town on customisation, and the car we primarily tested had stitching and colour in the carbon patterns to match its 'Ascari Blue' exterior, but you can pick whatever shade or combination of colours your budget allows.

Audi’s software is pretty good these days, with an attractive theme and fast hardware to back it, and the brand’s ‘Virtual Cockpit’ is still one of the most aesthetically pleasing and customisable digital instrument systems on the market, despite being one of the first.

As you might imagine, it's an individual design. Lots of Cactus cues, like the roof rails, bluff front end and stacked headlights Hyundai, uh, appropriated for the Kona. Curiously, no 'airbumps' along the side despite the C3 hatch having them...

The 17-inch wheels somehow look tiddly given the airspace over the wheels and I can report that black is not really this car's colour, even with the contrasting white roof and weird Mazda 121 Shades special edition venetian blind treatment on the quarter window. Bit of an '80s throwback there for you.

Lots more Cactus inside though, starting with the brilliant front seats, squared-off steering wheel and funky air vents. The little tray on top of the glove box is good, but it isn't rubber-lined, so that's annoying.

The Top Gun handbrake is hilarious but apart from the texturing of the fabric on the seats, it's a tad dark below the windowline. 

Okay, I promised a car with the practicality of an equivalent SUV, but it’s not quite there. The trade-off is still worth it, I promise, but there are a few areas where the RS6 isn’t as practical as you think it’s going to be, particularly for front occupants.

Yes, it’s a big wide car, with large but supportive seats and plenty of headroom, but the issue for those travelling in the front two seats is the surprisingly limited amount of storage.

Yes, there are two bottle holders in the centre console with a folding tray lid to hide them away, but they aren’t huge. Bigger bottles would have to go in the door bins, but even then they’re a bit height-constrained.

There’s a decent glove box on the passenger side, but even the centre console box is very shallow, with more than half of it taken up by a wireless phone charger.

The touch panel for the climate unit looks impressive but still can’t match having physical dials. It has clicky haptic feedback to your individual presses, and all the functions are permanently accessible instead of hidden in sub-menus, so if you’re going to make climate a touch-based interface, it doesn’t get much better than this.

Where the RS6 shines is in the back seat. Despite those big bucket front seats, I had heaps of room behind my own seating position (at 182cm tall), with lots of headroom and sufficient width in the cabin to spread out.

You sink into the rear seats, which are heavily contoured so riding in the back is a pretty good experience even on the track.

Rear passengers get four adjustable air vents in both the B pillars and in the centre, as well as their own touch panel for the rear climate zone.

USB power outlets are also available, and there are netted pockets on the front of both back seats, with a further two bottle holders in the drop-down armrest.

The centre seat is probably only good for kids, because there’s a very tall raise in the centre required for the driveshaft, eating all the legroom.

The boot is fairly large at 548 litres which is in mid-size SUV territory, although I will admit some performance SUV rivals offer closer to 600L.

Space expands to 1658L with the second row folded flat.

Even for a little car, the Aircross could do better. The lack of a proper cupholder provision for the car - a solitary spot at the rear of the centre console - is mildly baffling until you remember that this car is from France. The French hate a cupholder but, obviously, you can fit wine bottles in the doors.

It's worth repeating just how comfortable and supportive the front seats are on any given journey. Broad but supportive and somehow perfectly sprung, I would cheerfully rip out most other front seats and replace them with these.

The rear seats are less of these things and anyone who forces anyone to use the middle seat should be ashamed of themselves. The headroom is good back there, though.

The boot is a big one for the size of the car, swallowing 410 litres and expanding to 1289 litres with both rear seat sections folded.

A perennial Citroen problem is the price - at $32,990, the tiny SUV is doing battle with cars that are really a size up, coming in closer in size to the Venue than, say, the ASX.

That Yaris Hybrid price (we're all still reeling from that number) scores you a 17-inch alloys, a six-speaker stereo, climate control, front camera, reversing camera, keyless entry and start, front and rear parking sensors, cruise control, sat nav, halogen headlights (yep, you read that right), head-up display, leather wheel and shifter, auto parking, auto wipers and headlights, wireless charging pad and a space-saver spare.

The central touchscreen is annoying in that there are almost no hardware switches for functions like climate control. The software is a bit on the slow side, too, but you do get Android Auto and Apple CarPlay. The stereo is fine.

The RS6 is still packing eight cylinders in 2023, producing a massive 463kW/850Nm, somehow an increase (+22kW/50Nm) over the previous iteration.

Audi’s signature ‘Quattro’ all-wheel drive system is present alongside a limited-slip differential and four-wheel steering.

Air suspension and performance brakes and exhaust also feature, alongside an aggressive Continental SportContact 7 tyre package.

The 0-100km/h sprint time is now just 3.4 seconds, allowing you to show up even some electric cars, and the RS6 features 48-volt mild hybrid technology with a cylinder-on-demand system which can shut half the block down for more efficient coasting.

The transmission is an eight-speed torque converter unit which is smooth and effortless.

One of the great engines in mass-produced road cars today has found its way under the bonnet of the Aircross. Peugeot-Citroen's 1.2-litre three-cylinder turbo is a cracking engine, serving up 81kW/205Nm through a six-speed Aisin-sourced auto to the front wheels.

While the 11.8-second dash to 100km/h is, uh, leisurely, the torque figure means that on the move it's not as sluggish as that number or its 1200kg kerb weight would suggest.

Officially, the RS6 and its eight cylinders drink a combined 11.8L/100km, although even with its fancy hybrid system and cylinder deactivation, my time with the car saw 15.0L/100km. The RS6 has a 72-litre fuel tank and takes only the finest 98RON unleaded fuel.

Citroen claims a handy 6.6L/100km on the combined cycle and my week with the fizzy Frenchie included a trip over the hills and far away as well as a lot of suburban running. 

The digital display on the dashboard read 7.3L/100km, which isn't bad going without stop-start. It does require 95 RON premium fuel, though.

As you might have guessed from its impressive engine and performance equipment, the RS6 is a certified weapon on road and track.

On the road you can expect a quiet, refined cabin, superbly balanced steering for low and high speeds and a gentle ride quality courtesy of the pricey air set-up.

It’s as noisy or as quiet as you want it to be, with the cylinder deactivation toning things down at low speeds, and the engine roaring to life under heavy acceleration, or when the 'Dynamic' drive mode is selected.

It can at times be alarming how much the RS6 leaps to life, as it feels so cushy in a city, its width and cabin giving the feel of a luxury car rather than a performance one.

Make no mistake, though, the RS6 is properly quick, and when you give it a kick, it’s the roaring, aggressive machine the spec sheet suggests.

The best place for this? The track, of course. The big V8 and the capability of the all-wheel drive system are truly best explored at velocities impossible to legally achieve on the road.

Once you get past the bark and snarl of this wagon’s eight-cylinders at full force, and the lightning-fast shifts of its eight-speed automatic, you’ll have a moment to appreciate the way it simply holds to the tarmac when you tilt it into the corners, providing a balance when loaded up which only air suspension can provide.

The steering is awesome, communicating the texture of the road nicely to the driver, and requiring just the right amount of force to keep the car pointing where it needs to go.

The grip level is astounding with the huge tyres and the four-wheel steer system lets this hefty wagon take corners at a tighter angle than your brain initially allows.

Thankfully, the four-wheel steer system isn’t weird, either. While it can have a strange effect on some cars, in the RS6 it only bends your mind slightly when you tip it into a hairpin. Otherwise it feels pretty normal.

When everything is warmed up, it can let its guard down slightly and allows the driver to eke out a slide at the rear here and there for extra fun-factor

Jeez. What a machine. I guess this is what a quarter of a million dollars buys. A car that can do it all. Take the kids to the school in comfort and tear it up on the track like few other passenger cars on the same day.

There’s a caveat, though. A small one which looks like it will turn into a big one for cars like this in the near future.

I had the opportunity to drive the RS e-tron GT around the same circuit and it was better. Much better.

It was faster, more accurate, more composed. It was so effortless, I didn’t realise exactly how much quicker than the RS6 it was until I drove them back-to-back.

It’s a good sign for the future, but also a reminder a V8 like this isn’t the performance pinnacle it once was.

French cars have a very specific audience in this country, which includes weirdos like me. I've owned Peugeots and Renaults and loved every second of it.

Top of my list after my darling baby boy wrote off our family car (which was bought for him to drive), the Cactus was close to the top of the list. This fandom isn't blind, though - I know what I'm getting myself into having to dispassionately assess their faults and foibles as well as their triumphs and tangible benefits.

If I'm being honest - and it's just you and I here - I didn't think I'd like the C3 Aircross, there was just something about its SUV pretensions. I can't say the looks grabbed me and the inexplicable exclusion of the airbumps made me irrationally cross.

But once you slip behind that square-ish wheel into the comfortable embrace of those excellent seats, you forget the aesthetics (which did grow on me, even in black). 

The 1.2 turbo is, as ever, eager to please and well-matched to the six-speed auto. The two work well together to get you moving, although the engine is the noisiest installation I can remember. In the Peugeot 308, it's virtually silent.

On the move, the lovely ride also impresses, soaking up the bumps (except those aggressive rubber speed humps in shopping centre car parks) while keeping body roll to an acceptable minimum.

It's perfectly fine in the suburbs, even with its limited power. Breaking into traffic can be a bit of a moment, but there are slower cars about.

Where the Aircross is really good is out on the freeway. It's quiet for such a small car and that torque figure makes joining the M4 freeway (west out of Sydney) fine, and it cheerfully kept up on the climb up the Blue Mountains and the brakes and transmission were great down the other side.

Citroen is unashamedly about comfort over handling, but the trade-off for the comfort is pretty good in that it still handles despite a plush ride and being up on stilts.

Along with six airbags, ABS, stability and traction controls, the Aircross has low-speed AEB (up to 30km/h), blind-spot monitoring, lane departure warning, driver attention monitoring and speed sign recognition.

Three top tether anchors and two ISOFIX points complete the picture with a five-star Euro NCAP rating dating back to 2017. There is no corresponding ANCAP score, despite the agreement between the two agencies.

Five years and unlimited kilometres is the warranty length, and Audi’s ownership program includes invites to events like the one we were able to experience for the launch of this car. A track-test of the RS6 and the RS e-tron GT.

If you own one, I recommend them, you’ll learn a thing or two about the car and possibly yourself while you’re at it.

Servicing is required once every 12 months or 15,000km, and a service pack covering the first five years or 75,000km can be purchased alongside the car at a cost of $4360.

It works out at $872 per year, which isn't economy car cheap, but with such a complex drivetrain, what did you expect?

Citroen offers a class-competitive five-year/unlimited kilometre warranty with a five year service plan if you want to pre-pay.

That plan costs a stiff $2727 for your five visits (or every 12 months/15,000km). That's nearly three times what you'll pay for a C-HR or about $400 more than a Mazda CX-3.
