Audi RS3 vs Audi RS6

What's the difference?

The Audi RS3 is a special hot hatch and sedan I’m so glad I experienced before its five-cylinder engine is inevitably retired due to emissions regulations. Full of character and charisma, this car is far from a rational purchase, pitched at boy racers who don’t want to grow up just yet.

From a value perspective, too, while the asking price has crossed the six-figure threshold and the option prices add thousands, it’s still much cheaper than the Mercedes-AMG A45 S. Make of that what you will.

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.

Audi has made some subtle tweaks to the RS3 that has somehow made this snarling hot hatch look even angrier.

Up front there’s a new fascia featuring more open sections, which in turn improves air flow. A black styling package is now standard so it almost looks like the entire front is open and ready to eat you alive.

The matrix LED headlights now have a darkened finish which adds to the menacing look. There are new signatures, including a special chequered flag one for the RS3 which looks top notch.

Around the side it surprises me just how much wider the front is compared to the rear. Both have big, muscular haunches, but it shows this hot hatch is a bit of a bulldog. I’m a big fan.

These haunches stand out even more when you opt for the new Daytona Grey Matte exterior paint. While the extra $11,400 for the privilege makes me wince, it looks sexy on this car.

The standard 19-inch ‘Y-spoke’ alloy wheel design remains unchanged from the pre-update car, though there’s a new, optional ‘cross-spoke’ design that looks delicious (and tricky to clean).

At the back there’s still the classic RS dual exhaust tip motif which looks mean and it’s surrounded by a new black rear diffuser with a motorsport-inspired vertical red reflector in the centre.

The new LED tail-light signature with the vertical slats is so clean and neat. It looks particularly great in low-light situations or at night.

Inside, the biggest change is the new RS steering wheel with the flat top and bottom. As standard it’s wrapped in perforated leather, but with the optional RS Design package it’s wrapped in 'Dinamica' synthetic suede. I much prefer the standard leather-wrapped unit as the Dinamica likely won’t last in the long run, especially if you’ve got clammy hands.

Other changes include more interior ambient lighting on the door cards through small slits, as well as a new shift-by-wire gear selector. The digital instrument cluster and touchscreen multimedia system set-up remains unchanged which is no bad thing because they look fantastic.

It’s disappointing Audi has stuck with an extensive use of piano black on the centre console because this gets dusty and grimy very quickly, and then can get scratched easily when wiped clean. It now also features on the steering wheel buttons, which are frequent touchpoints.

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.

The RS3’s standard sport front seats are deliciously comfortable and offer plenty of electric adjustment. This means people of any size and stature should be able to find their desired seating position.

Thanks to the electric lumbar there’s also a massage function for the front seats. This is pretty cool to flick on and relax into, but I wish the massage was a little stronger.

While the new steering wheel looks cool interacting with the buttons on it can be a bit of a hassle. They’re touch-sensitive but do have a satisfying click if pressed harder.

There were moments where I accidentally clicked on the buttons during intensive track driving as my hands were at the nine and three o’clock positions. Not the best thing when you’re meant to be focussing.

The digital instrument cluster offers so much configuration you won’t know what to do with yourself. There’s even a new rev counter design especially for the RS3 which looks very cool.

Moving across, the touchscreen multimedia system is classic Audi. It’s easy to navigate around and hard to get lost in the sub-menus. There’s also wireless Apple CarPlay and Android Auto connectivity which is virtually a given now.

While you need to use the touchscreen for a number of features, I appreciate how Audi has retained so much physical switchgear up front. It’s particularly handy to have physical toggle switches and a small digital display that’s separate from the touchscreen for the climate control.

Another piece of physical switchgear I like up front is the rotary dial for the media controls on centre console. It’s much like an iPod, allowing you to change the volume if you rotate your finger on it like a click-wheel. Major throwback vibes.

In terms of storage up front, it’s decent but not outstanding. There are two cupholders, a wireless phone charger, a centre console box as well as a lockable glove box.

Moving to the second row, it’s clear it’s more for the sake of it, rather than having a space you’d want to use all the time. At a leggy 182cm tall, I have minimal legroom behind my own driving position.

With headroom, it’s adequate in the hatchback and not great in the lower-slung sedan. I need to kink my neck in the latter to fit, which isn’t comfortable.

The second-row bench seat is comfortable, offering enough support for short-to-medium trips. I wouldn’t want to get stuck back there for too long, however.

In terms of amenities, there are air vents mounted on the back of the centre console with a dedicated third zone of climate control, two USB-C ports, nets on the seat backs as well as a fold-down centre armrest with cupholders.

At the back there’s a power tailgate for the hatchback, however the sedan only has a power-opening boot lid. This means you need to manually shut it, which isn’t uncommon for sedans.

Boot space in the RS3 is a weak spot due to all the componentry for the all-wheel drive system and the tricky rear clutch set-up. There’s only 282L for the hatch and 321L for the sedan, which isn’t much.

In reality, however, the boot space is still usable. It’s fairly square and there’s barely any boot lip, meaning you can slide things in and out with ease.

Boot-related amenities include a netting system to keep things from sliding around, a light, some hooks and a 12V socket. There’s also a parcel cover for the hatchback.

Unfortunately there’s no spare wheel of any kind under the boot floor in the RS3 as this is where the 12V battery lives. Instead there’s a tyre repair kit. This isn’t uncommon in performance cars, though it’s disappointing if you frequently travel in the country, away from tyre repair shops.

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 Audi RS3 is still powered by a 2.5-litre turbocharged five-cylinder petrol engine which produces an unchanged 294kW of power and 500Nm of torque.

This is mated to a seven-speed dual-clutch automatic transmission with drive sent through an all-wheel drive system.

Audi claims both versions of the RS3 can do the 0-100km/h sprint in just 3.8 seconds, which is technically 0.1 seconds faster than a Mercedes-AMG A45 S. Top speed is electronically limited to 250km/h.

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 Audi RS3 sedan is claimed to consume 8.2L/100km, whereas the RS3 hatch is claimed to consume 8.3L/100km, both on the combined (urban/extra-urban) cycle (ADR 81/02).

Both body types come with a 55L fuel tank and require a minimum of 98 RON premium unleaded petrol.

During my testing I saw an average of 9.6L/100km according to the trip computer. We did around 200km of higher speed driving heading east out of Melbourne, including some spirited sections.

Our on-test figure translates to a range of 570km on a full tank of petrol.

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.

Spoiler alert, it’s a cracker.

Starting up the RS3, you’re instantly aware you’re behind the wheel of something special. Audi has made the start-up more “emotional” with this update and also “optimised” the exhaust flap control for more five-cylinder growl across a wider rev range.

When you’re on the boil, this five-cylinder sounds so fantastic. It’s the clear centrepiece of this car and I’m so happy Audi has continued to offer it.

However, thanks to the addition of a petrol particulate filter (PPF) with this latest-generation model it sounds a little muted in everyday driving. Call me a boy racer, but I want more noise.

Staying on the engine, it’s full of character and gets this small hatch and sedan moving along with ease. Even though the outputs are unchanged with this update, it’s still more than enough; 0-100km/h in 3.8 seconds shows it's more than enough.

The seven-speed dual-clutch automatic transmission in this car keeps the acceleration feeling relentless with snappy gear changes at a moment’s notice. It’s particularly fun taking control of moving between the ratios with the paddle shifters.

In slow-moving traffic, however, the dual-clutch can get a little lost and stuttery, which is a classic characteristic of this kind of transmission.

As standard the all-wheel drive system remains neutral, keeping the front and rear balanced and in check. However, if you flick to the ‘Dynamic’ drive mode you get more rear-biased action which is fun when you exit a corner with some extra heat.

There’s also still a ‘RS torque rear’ drive mode which is essentially a drift mode. Unfortunately we didn’t get to sample this during the launch program.

Additionally, there’s an ‘Individual’ mode that allows you to choose your own destiny. You could spend hours here fine-tuning your desired drive mode which is both great to see but complete nerd-core.

Like the pre-update car, there’s an electronically controlled multi-disc clutch on the rear axle which actively splits the torque between the rear wheels. However, it’s been "optimised" to allow for quicker cornering.

While this is hard to gauge without testing the pre-update and current car back-to-back, the RS3 is so dynamic it feels like you only scratch the surface on public roads. Thankfully we got to see how far we could push it on Haunted Hills, which is a fantastically complicated hill climb circuit in eastern Victoria.

In terms of the steering, there’s a progressive rack as standard which ramps up the steering intensity the more you turn the wheel. In practice, this means the lock-to-lock ratio is very short, making it easy to link up tight corners.

It also makes it easy to navigate tighter driving scenarios, like parking, though it disguises how wide the turning circle is. Expect to do three-point turns fairly often.

For the suspension, the RS3 has adaptive dampers set-up that generally errs on the sportier and firm side. There is a ‘Comfort’ mode which irons out some bumps, but larger road imperfections still transmit harshly into the cabin.

It’s also worth noting at higher speeds there’s a considerable amount of road and tyre noise that comes into the cabin. Thankfully the Sonos sound system does a great job at drowning this out.

Lastly, the safety systems in this car are generally user-friendly, though the lane-keep assist can be a little too hands-on, especially on narrow roads with poor lane markings. Thankfully you can switch this off by pressing and holding a button on the end of the indicator stalk.

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. 

Like all Audis, the RS3 is covered by a five-year, unlimited-kilometre warranty. There’s also five years of roadside assistance.

Logbook servicing is required every 12 months or 15,000km, whichever comes first.

You’re able to purchase a five-year pre-paid service package for $4010. That averages out to $802 per service, which seems like a lot until you see how much Mercedes-AMG charges to service an A45 S.

RS3 owners can also purchase two-year packages to extend the warranty, roadside assistance and servicing coverage. This allows new RS3 owners to have warranty coverage for up to nine years and it’s transferable to future owners.

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?
