2023 Audi RS3 vs 2024 Audi RS6

What's the difference?

If conventionally powered cars really are on the endangered list, it’s vehicles like the Audi RS3 that will remind us what we’ve lost. There’s so much fun to be had in this car, that you really need to take it to a track to tap into it safely and responsibly. And there’s the rub.

While there’s no doubting the RS3’s potential, neither is there any doubt that the driveline absolutely dominates the experience. In fact, we reckon the S3 with its more modest (but still ample) performance and friendlier nature is probably the smarter car for the everyday. It’s also cheaper by about $20,000 and while it lacks the aggressive looks, it’s still a charming car. Perhaps all the more charming for its easier-going nature and balance of abilities.

So why buy the RS3? Because it’s the one that will keep you entertained for longer if you’re a serious enthusiast driver. But if you don’t plan to use the car for track days, there’s a strong argument that the RS3 is way more car than you’ll ever need. Of course, that sentiment never stopped performance-car lovers, did it?

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.

While the overall shape of the RS3 suggests evolution rather than revolution, the RS3 treatment has led to a much sportier look. We still reckon the sedan is the pick of the two body styles, mainly because it looks a bit more aggressive. Certainly, though, an aggressive look is not something either version backs away from, and those deep, wide blacked-out honeycomb grilles front and rear give the thing lots of presence.

So too do the blistered fenders, allowing for the extra track width that gives the RS3 its unique footprint. The front track itself is 30mm wider, but the wider fenders also gave Audi the chance to do some creative aero-management. Unlike, say, the Toyota Supra, for instance, with its faux vents up each side, the RS3’s lower-front vents and aero-slits behind each front fender are fully functional, directing air into the engine bay and away from the brakes respectively.

Another really neat function is the LED daytime running lights’ one-act play when you unlock the doors. As the car unlocks its doors, the LEDs spell out `R’, `S’ and `3’in sequence. Blink and you’ll miss it, but it’s a lovely touch that some manufacturers will never understand.

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.

Like the rest of the Audi A-series range, the RS3 is available in two body styles, a five-door hatchback and a four-door sedan. The five-door hatchback layout is the most practical of the two RS3 layouts, but both feature plenty of front-seat space and a rear seat that folds 40:20:40. 

Paddle shifters are mounted on the steering wheel rather than the column, so they move with the wheel. That can make it difficult to select the correct paddle in a hurry with lots of lock applied.

The Drive modes are operated by a switch low down on the centre-stack that is clearly designed for left-hand-drive cars. It’s too far from the driver and needs to be cycled through in one direction, rather than being able to select the next mode or the previous one.

Beyond that, the interior is a lesson to other car-makers on how to get an interior right. There’s a quality look and feel with the possible exception of the plastic trim below the passenger-side air-vents which looks and feels a bit cheap. There are plenty of cup-holders and cubbies around the cabin with two USB plugs in the front and two in the rear (for charging).

The RS3 loses some space compared to the regular A3 because of the performance hardware. Where the hatch can take 282 litres with all seats in place (1104L with second row stowed), the sedan can swallow 321 litres.

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.

While the five-cylinder engine is more or less a carry-over from the previous RS3 model, the end result is still a pretty stunning one. With 2.5 litres of capacity, the turbocharged unit accounts for 294kW of power (the same as the previous model) and 500Nm of torque (up 20Nm).

The transmission is a seven-speed dual-clutch unit that is quite a familiar sight around Audi by now, and the all-wheel-drive system uses a centre differential with an electronic clutch-pack on each rear axle to give the car a Drift mode (although Audi insists you don’t refer to it in those terms) as well as torque vectoring with the ability to shift 100 per cent of rear-axle torque to the either wheel to maximise grip.

There’s now also an RS-specific exhaust system with an active flap to increase or tame exhaust noise according to which drive model is selected. The drive modes themselves stretch form Comfort to Auto to Dynamic, altering shift points, gear-shift aggression, throttle response and suspension firmness as well as that exhaust flap.

Brakes are enormous 375mm front rotors with six-piston calipers, that hardware forcing the fitment of a 19-inch alloy wheel (specific to the RS3) for brake clearance.

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.

Audi’s official combined fuel consumption figure for this car is 8.3 litres per 100km. Obviously, start using all that power and torque and that figure will grow significantly. Based on that, the car emits 190 grams of CO2 per kilometre, and with the 55-litre tank (which looks a bit small on paper) the range should still be around 600km between fill-ups.

The only catch with that is the high-tech nature of the engine means it requires the more expensive, Premium ULP at the bowser.

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 impressions are that this is a typical Audi in the way it fits together beautifully and is made from quality materials. The ergonomics – particularly the virtual cockpit - are spot on and it even smells like an Audi. Noise is well suppressed, the controls feel quality and the front seats are comfy. But from there, the overarching view is dominated by that powerhouse of an engine.

This isn’t just a quick car, it’s actually brutal in the way it builds boost almost immediately and then hurls the car down the road. To be honest, it’s almost too much, and the way the RS3 reels in the horizon will leave some drivers ignoring other sensory inputs in order to keep up with the car. Brutality breeds brutality, too, and the subsequent steering and braking inputs required when the throttle is pinned will not always be the considered, gentle type; they’ll often be gut reactions.

Thankfully, the rest of the driveline and platform has the smarts to make all this work. There’s awesome grip from the Quattro all-wheel-drive system and the car stays flat and steers in a fast, neutral but pin-sharp way. The dual-clutch transmission feels perfect for the engine, too, with ultra-quick shifts that become more aggressive as you ramp up the drive modes. Ride quality is good but we reckon there’s less bandwidth in the various drive mode settings than exists in the same system fitted to the S3 model we drove a few months ago. While the latter offered a broad range of suspension firmness, the RS3 seems to be a bit of a prisoner of its own performance, with Audi leaning all the drive modes towards a firmer setting in the name of body control.

That’s supported by Audi’s decision to offer us some race-tack laps in the RS3 to safely explore its high-end tendencies. At this point, the car emerges as a proper track-day proposition, all that power and control blending into a car that loves being thrown around a circuit. Perhaps the front seats could do with a little more side bolstering at track-cornering speeds, but overall, it’s clear that the RS3’s brief does, indeed, include a degree of race-track use.

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. 

Service intervals for the RS3 are every 12 months or 15,000km, whichever comes first. Audi offers capped-price servicing for the RS3 at $3580 which covers servicing costs for the first five years.

The car is covered by Audi’s five-year/unlimited kilometre warranty. The vehicle is also protected against body-rust perforation for 12 years.

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?
