Audi RS3 vs Audi S3

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?

There are plenty of historical instances where a particular model within a broader range manages to hit the absolute sweet spot even though it’s not the fastest or most expensive variant. Porsche’s GTS specification across various models is a great example of this.

And at the risk of being proven wrong when the all-new RS3 comes along later this year, this car, the S3, might just pull off that feat.

Yes, the new RS3 will be more powerful and will offer even more grip and sporty flavour, but it will also be more expensive. And we defy anybody to drive the S3 and say that it lacks dynamism in any single area.

It’s also a magnificently balanced car with the right amount of attention paid to every aspect of its trim and performance. That, in essence, is where that `balanced’ label originates and even though it’s felt most in the actual driving experience, it permeates throughout the entire vehicle.

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.

Perhaps the most striking thing about the styling of the new Audi is just how similar it looks to the old model. Okay, this is not a new thing with Audi which has made a point of not throwing a handsome design into the dumpster in pursuit of new for new’s sake.

As such, the exterior lines are taut and typically Audi clean and, with the latest LED headlights and a refinement of the Audi trapezoidal grille, the look is fresh and crisp without being a novelty act.

Inside, the virtual dash display and large, relatively flat centre console almost amount to anti-styling. Or it would if the rest of the deal wasn’t so sharply angled towards a philosophy of less is more.

Again, this is classic modern-era Audi where the game is to make a complex layout look as simple as possible. The face-level air vents also seem to have borrowed a little Lamborghini (part of the Audi family) DNA.

I particularly like the new shift-by-wire gear selector which is a nifty looking switch but works just as intuitively as a conventional shift lever. New tech meets old muscle memory, I’m calling it.

It's worth mentioning (again) just how good Audi’s customisable dashboard display is. With sharp, clear graphics and the ability for the driver to prioritise the information on display at the time, the S3’s display is still about the best in the business.

Overall, ergonomics have always been a long-suit of this brand and there’s been a clear intention to follow that tradition this time around.

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.

While SUV owners are often quick to tell you that they bought their car for its interior space, the truth is sometimes different. And without the huge wheel-wells and suspension towers of a high-riding SUV, the conventional hatch or sedan often has an advantage.

Certainly, there’s no lack of room in the S3 and the hatchback version has a wide hatch opening to make loading easier. The sedan, however, is a full 150mm longer than the hatch and that extra is all behind the rear seat.

So the boot is actually very useable with a capacity of 325 litres. Audi claims the same 325 litres for the Sportback, but that figure jumps to 1145 litres with the rear seat folded flat.

The rear seat in either variant is handily split 40/20/40 and there are storage nets on the back of each front seat, luggage nets in the cargo area and 12-volt outlets in both the centre-rear and luggage compartment. Even floor mats are standard.

There’s only one trim level across the S3 range, so it doesn’t matter whether you choose the sedan or hatch, the level of standard kit remains the same. And extensive.

As with many performance variants of a platform, what you’re paying for in the S3 is the hardware that allows it to be a more aggressive, more involving drive. So, compared with the A3, the S3 gets much more engine performance, bigger brakes and improved suspension.

Inside, the S3 runs to S-specific trim and presentation (instrument display, steering wheel) standard heated, powered, four-way lumbar-adjustable sports seats, a black headliner and the 15-speaker Bang & Olufsen stereo that’s a $1500 option on some variants of the A3.

The interior is also home to a 10.1-inch info screen, dual-zone climate-control, an auto-dimming mirror, keyless entry and push-button start, wireless phone charging, rain-sensing wipers, park-assistance and acts as a Wi-Fi hotspot. Connectivity runs to Android Auto, Apple CarPlay and sat-nav.

Helping the image match the performance, the S3 also gets dark aluminium accents, alloy pedals, ambient lighting and gloss-red brake calipers to give it the visual punch the price-tag suggests.

Speaking of price, the new S3 represents a fair hike over the outgoing S3, and a sticker of $70,700 for the Sportback and $73,200 for the sedan means the new model will be tickling the $80,000-mark as a drive-away proposition.

Compared with the old model, those prices represent a leap of around $6000, not to mention a spike of around $23,000 or $24,000 over the entry-level versions of the new A3 on which it’s based.

But perhaps a more meaningful comparison is with the 40 TFSI variants of the new A3 which also feature Audi’s famous Quattro all-wheel drive system.

In that case, the price difference between the A3 and S3 is closer to $17,000; closer, but still a big tweak to the monthly lease repayment.

Given you’re starting with a premium-priced product to begin with in the A3, the extra performance and dynamics offered up by the S3 seems to be reasonably priced given the scope of their influence.

Again, you need to see it through the prism of high-end motoring, but when you do, you can see where the money has gone.

And if you have even more to outlay, there’s always the 'Premium Plus' package for the S3. That gets you a panoramic glass sunroof, head-up instrument display, 360-degree cameras, a memory function for the driver’s seat (which should be standard at this end of the market) and a memory function for the exterior mirrors. Yours for an extra $3990, which, given some makers charge that just for the sunroof, seems a pretty reasonably proposition.

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.

Here’s where a lot of the extra currency demanded for the S3 goes. Forget the 1.5-litre engine in the base-model A3, and instead move to the two-litre four-cylinder as seen in the A4 40 TFSI. Then, add extra turbo-boost (up to 1.8 bar thanks to an efficient intercooler) different variable valve timing protocols, and a direct fuel-injection system with a specific calibration and the potential to create injector pressures of up to 350 bar, and you have the S3’s powerplant.

Maximum power is 228kW at anywhere from 5450 to 6500rpm, and maximum torque of 400Nm produced in a broad range between 2000 and 5450rpm.

Transmission is a seven-speed dual-clutch unit driving through all four wheels as per Audi’s Quattro mantra, although it’s important to note this version of Quattro is the simpler, arguably less pure, on-demand system where the car behaves as a front-drive platform until the all-wheel-drive system is required to step in.

That said, with 228kW under its wheels, that’s a fair bit of the time. And compared with previous systems, this one takes more notice of driver inputs and wheel-speed to be less reactive and more active.

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.

Audi quotes an official combined cycle fuel consumption figure of 7.4L/100km for the A3 Sportback and 7.3 litres for the sedan.

That difference is a bit of a mystery given the sedan is heavier (by just five kilograms) until you consider that the combined figure includes freeway running, at which point the sedan’s extra 150mm of length and different rear diffuser may be the aerodynamic deal-breaker.

The Sportback emits 170 grams of CO2 per kilometre (166 for the sedan) and with the 55-litre tank fitted, both variants should have a range of around 750km between fill-ups.

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.

Some cars take a few minutes at the wheel before they start to get chatty. Not so the S3. From the moment you grab the lovely leather tiller, haul it into gear and give the perky little turbo-motor a squeeze on the throttle, the Audi is making all the right noises and giving clear, precise feedback on its every move.

Sometimes, cars with lots of tyre, lots of all-wheel drive grip and the sort of sharp steering fitted here, can start to feed back so many responses that it becomes difficult to know which one to respond to.

Not the S3, which seems tuned to a keener driver’s priorities (as it should be, of course). As a result, the steering feedback is distinct from what the rest of the front end is doing and everything else going on is clear, quantifiable and designed to improve the experience.

That even extends to the soundtrack which, Audi told us does not use any electronics to improve it beyond amplifying the engine-bay harmonics which use the windscreen and scuttle as their 'speaker.'

Combined with the active exhaust system, this car honestly sounds like a five-cylinder engine (I opened the bonnet to count the spark plugs to make sure it wasn’t. It isn’t.)

If you’ve ever driven a five-cylinder Audi or a V10-powered R8 (two in-line fives, really) the tune will be a familiar one. Lovely, and – again - such amazing attention to detail.

The 2.0-litre engine runs fairly high boost levels, but that doesn’t seem to have affected the way it storms off the mark. Neither does the dual-clutch transmission contribute any delay, provided you haven’t managed to stand on the brake and throttle at the same time (as many left-foot brakers might).

At that point, the driveline goes into sulk mode and will force you to wait a heartbeat or two before full power is restored. This can be an issue when trying to dart across a busy intersection or merge into a traffic flow.

It’s not a new thing to Audis, but remains an annoyance to those of us who equate having two pedals with having two feet.

The driver-selectable drive modes fitted to the S3 are interesting inasmuch as they actually make a meaningful difference to the way the car operates. They alter the transmission shift points, the throttle sensitivity, steering weight and damper settings.

'Comfort' mode will be the default for most owners, and while 'Dynamic' does sharpen up the dampers ever-so-slightly beyond an acceptable day-to-day level of firmness, it also adds weight to the steering feedback.

Frankly, I don’t think it needs it and simply adding resistance feels like a token gesture. And since the steering has a (non-negotiable) variable rate in the first place, bigger inputs equal a bigger proportionate change of direction anyway.

The damping control is now the more sophisticated magnetic-hydraulic type where hydraulic pressure varies the valving rather than the simpler, previous system of energising an electro-magnet to alter the viscosity of the damping fluid.

This more finite control system has allowed more 'bandwidth' as Audi puts it, between Comfort and Dynamic damper settings.

While the auto mode is almost prescient, it’s not actually pre-emptive but rather takes into account suspension deflection, wheel-speed and driver inputs to come up with a combination of settings to make the most of the situation.

And if you really want to fiddle, you can choose 'Individual' and create an overall setting that combines bits of Comfort and Dynamic with a smattering of 'Efficiency' thrown in.

Toggle down to Dynamic and throw the S3 at some bends and it soon emerges as a pretty gripped-up piece of equipment. The front-drive bias is not really noticeable, but then neither is the transition where the computer begins to engage the rear multi-plate clutch to turn the rear axle into an active participant.

There’s certainly no lack of grip at any stage of a typical corner, and even the odd unexpected damp patch poses no awkward questions. Perhaps the biggest grumble would be the tyre roar at highway speeds, but that’s often the price of performance rubber.

No surprises for guessing that Audi has this angle absolutely covered.

Some driver-assistance technologies have now filtered down from larger more expensive Audi models, and are standard fitment on the S3. Those include collision-avoidance assistance, lane-departure warning, rear cross-traffic assistance and parking assistance programs.

There’s also adaptive cruise-control, hands-on detection, traffic-jam assist, exit warning, a rear-view camera and a tyre-pressure monitoring system.

You also get the usual six air-bags including side-front bags and curtain air-bags at head height for rear-seat passengers. The S3 also gets a centre-front air-bag; a move that is likely to become a lot more widespread in the not-too-distant future and is designed to avoid head clashes between the front-seat passengers in a side impact.

Autonomous emergency braking is fitted and can also detect pedestrians and cyclists; a first for the S3.

The S3 scored a maximum five stars for safety in ANCAP testing.

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.

Audi has finally had to cave in and extend its warranty to match its competition. So, any new Audi sold after January 1 this year moves up to a five-year/unlimited kilometre factory warranty; a big step up from the previous three years of cover.

S3 buyers can also opt for Audi’s five-year service plan which costs $2580. Servicing is set down for every 15,000km or 12 months.
