Audi A3 vs Audi RS6

What's the difference?

Closing in on $60,000 for a small car isn’t cheap. Ask a car dealer and they might even say the hatchback is a good way to get someone into a showroom to eventually look at an SUV.

But I reckon you’d be doing the A3 a disservice to count it out. It’s always been one of those cars that does everything well, and with this current facelift manages to keep its practicality without becoming boring.

It looks good on the outside, it’s smart on the inside and it’s fun to drive while remaining sensible. Even if you get it in bright yellow.

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.

Eye of the beholder and all that, sure, but the A3 looks cool from the outside. It’s got this angular design but manages it without being too aggressive or busy with other design elements, so it still has a ‘premium Euro’ feel to it.

Shooting pics of the car for this review, the harsh light accentuated its sharp lines. It looks sculptural rather than just some little blob. 

At the same time, thanks to the proliferation of sports design packs like the S Line, The A3 looks like it could be an S3, almost. Which makes sense, because the front bumper and rear diffuser as well as the roof spoiler are all partly inspired by RS models.

New for the A3 is the flat, 2D Audi badge, the model name on the B pillar and the new font for its name on the tailgate. 

The lights in the cluster are able to look narrower than before thanks to their customisable settings, which allow you to choose the light signature, while the grille has a flatter appearance and the air intakes are bigger. Even the wheels look like they’re from a sports car.

Whether you’d have the A3 in the Python Yellow of our test car is another thing. I don’t mind a loud colour but I reckon a bit of 'District Green', 'Ascari Blue' or 'Progressive Red' would be the vibe.

Also, any colour that isn’t white is a cost-option on the A3, all of them coming in at $1350, except Ascari Blue which is an Audi Sport colour and costs $1850.

Speaking of the vibe, inside the A3 feels properly nice. It’s not just a spruced up Golf in there. There’s proper Audi character to the car, though that means plenty of piano black trim to get smudgy.

Audi’s done a good job making the layout look sleek without resorting to locating all the controls in the screen. There are design elements in the cabin that aren't strictly necessary but are worth doing for the way they look.

Things like the way the vents flank the driver display or the trim inlay on the passenger side of the dash.

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.

Starting from what’s right in front of you as a driver, the steering wheel is the same as in bigger, more expensive Audis. That’s a good thing, because it’s nice to hold, has a good shape for the nine-and-three hand position and it’s not too thick. 

As well as the nice, clear buttons on the wheel, you’ve got some physical controls for the climate control and some of the vehicle functions like parking assist and stop-start under the multimedia screen.

For a car this size, the 10.1-inch central touchscreen is plenty big enough, and the fact it doesn't sit up high over the dash is great. It's like a perfect arm's length for your standard-sized adult (like me). I can reach the other side of the screen without needing to lean.

The fact there’s no head-up display is a bit of a let-down, but the now-standard 12.3-inch driver display is very good. It’s configurable yet clear, and means you can get detailed navigation information in front of you rather than having to look to the multimedia screen. 

The test A3 has genuine leather upholstery, which is $1100 extra. Not the most you’d pay for leather seats in a Euro, and the seats are comfortable. They're nicely bolstered, the drivers’ side is electrically adjustable and the leather doesn’t feel hard or rough to the touch.

Sitting behind my own seating position in the second row is a little tight, however. At 178cm, my knees almost touch the seat in front. There's also no sunroof, and even though there's just about enough light, that omission doesn’t help the cramped feeling.

There are, like the front, two USB-C ports and the air vents in the back, the latter separately adjustable to avoid arguments, though the cupholders in the armrest are in an awkwardly central position.

Behind that, under the 380-litre boot's floor is a space-saver spare tyre. That's better than some SUVs designed for family adventures that only offer up an inflator/repair kit. Keep that up, Audi. Good job. Well done. 

If you fold the rear seats, you get 1200 litres of space. Interestingly, those luggage space figures are the same as the BMW 1 Series.

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.

Let’s start with the bad news. Most people can’t afford one of these. The RS6, in all of its muscular glory, is more expensive than ever before. Now wearing a before-on-roads price-tag of $241,500, it’s hardly your average mum and dad family hauler. But then, there’s nothing average about the RS6.

It’s so well regarded amongst enthusiasts for multiple reasons. It’s the biggest meanest wagon you can buy, and somehow Audi has managed to make this version more powerful and even faster than before.

In fact, it’s one of the few normal looking combustion cars out there which can still hold a candle to many electric cars, with its whomping V8 helping it warp from 0 to 100km/h in just 3.4 seconds.

More on those performance specs later. If you’re wondering what else you get for your near-quarter-of-a-mill it’s pretty much every spec item Audi currently offers.

There are now lighter 22-inch alloy wheels, adaptive air suspension, a high-performance braking system, an RS-specific exhaust system, matrix LED headlights with adaptive high beams, a 10.1-inch multimedia touchscreen with navigation and wireless phone mirroring and one of the best digital instrument clusters on the market.

It also features Valcona leather interior trim, sporty bucket seats with perforated trim, honeycomb stitching, as well as ventilation and heating, additional cabin trim in synthetic suede (comprised of 45 per cent recycled fibres), ambient interior lighting and a panoramic sunroof.

It’s a lot of stuff, but one thing you get a little less of is sound insulation. Audi has chosen to remove some of it this time around so you can hear the V8 better from behind the wheel.

The A3 is powered by a 1.5-litre, turbocharged four-cylinder petrol engine that makes 110kW and 250Nm.

It drives the front wheels via a seven-speed dual-clutch auto transmission and it can hit 100km/h in a claimed 8.1 seconds.

It’s also got a 48-volt mild hybrid system to help with efficiency, though you’d need to be told about it to notice. It also helps with the A3’s (smooth) stop-start system.

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.

The A3’s 50-litre fuel tank needs to be filled with RON 95 premium fuel and it’ll drink a claimed 5.3-litres per 100km on the combined (urban/extra-urban) cycle.

Theoretically you’re topping 900km a tank there, but given how fun this car is to drive you’d have to be well behaved to get even close.

For reference, whenever I was on a normal, day-to-day drive on test the A3's trip computer was returning figures in the mid to high sixes.

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.

First things first, the A3’s exterior and S Line pack are a clue to the way the car drives. It’s probably not the perfect car if you like a cushy, soft ride. 

Its suspension errs towards the stiffer side of things, and certain bumps can feel more significant than they need to. But even on particularly bad roads or tram tracks in the city the dampers do a decent job of soaking up the harsh stuff.

It also means there’s more road noise than you’d like on some older highway surfaces, but only in a way that might get annoying if you’re on a road trip with the stereo off for some reason.

The upside of that is its steering feels well weighted and accurate. Plus, the way it handles and corners feels like a bit more grunt would make this a proper driver's car.

It’s not too intense, and there’s enough feedback to make it feel like the A3 shouldn't be a city-dweller only when it comes to driving.

Of course, it’s a hatchback, so you've got the advantages that come with less weight and a lower centre of gravity. 

It doesn’t have enough weight to push into understeer more than you’d like on a tight corner. But it also doesn’t feel so light that you’re not sure how it’s going to behave under sharp braking.

The A3’s drivetrain, despite looking underwhelming on paper, feels practical on the road. Sure, 110kW isn't anything wicked, but its 250Nm feel like they’re working in the right places - that being between 1500 and 3500rpm. 

It isn't blisteringly quick but even with the seven-speed transmission operating in default auto mode it usually feels like it's in the right place, let alone chipping in with 'manual' shifts via the paddles or shifting drive modes. The A3 has a choice of 'Normal' and 'Sport' shift settings.

You might be a little disappointed if you thought you’d be getting anything approaching a hot hatch, but for an entry-level model the A3 more than holds its own. It’s a solid platform that performs well without compromising too much when it comes to daily driving ability.

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.

Like its standard cabin equipment, the RS6 has had the entire catalogue thrown at it for active safety gear. Included is freeway-speed auto emergency braking with pedestrian, cyclist, and intersection detection, lane keep assist with lane departure warning, blind-spot monitoring with rear cross-traffic alert, an exit warning system, and adaptve cruise control with traffic jam assist.

Elsewhere the RS6 gets dual front, dual side, and head curtain airbags, with ISOFIX points on the outer two rear seats as well as three top-tethers across the rear row.

The RS6 is not safety rated by ANCAP, but the rest of the A6 range was awarded a maximum five stars in 2018. 

Audi offers a five-year/unlimited kilometre warranty, which is about par for a premium brand, but it also offers five years' free roadside assist and the ability to pay to extend the warranty.

Servicing is $2520 for a five year plan, but the extended two years of 'Audi Advantage' warranty is $3250 and comes with unlimited kilometres, roadside assist and covers two services.

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?
