Audi A1 vs Audi S3

What's the difference?

If you’re eager for a sporty compact hatchback with premium design and luxury car badges, the Audi A1 40 TFSI is a very, very strong contender. It’s fast, fun, and functional for a little hatchback. It’s just very expensive, and for most people the $10K cheaper 35 TFSI model will tick most of the boxes. I’d recommend you drive it before signing on for the top-spec model.

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

I don’t think I’ve seen a better transformation between generations than the current A1. In its previous guise it was bubbly and cute, but now it’s an angular brute.

This version’s S line sports body kit and funky 18-inch alloy wheels certainly help in that regard, but even the standard lighting signatures - LEDs front and rear - make it stand out as anything but a cutie pie city car.

The good news is that it hasn’t grown too much, either. Sure, it is a bit bigger, measuring 4029mm (on a 2563mm wheelbase), 1740mm wide and 1409mm tall. The last one was smaller (3973mm long on a 2469mm wheelbase, 1746mm wide and 1422mm tall), but this one isn’t elephantine in its proportions and so remains simple to park and squeezy enough to be considered a Light Car by industry standards.

And there are some really, really playful colours available. Like this Turbo Blue (which is only for this spec), and Python Yellow. There’s also black, green, red, three different greys, and two whites. The only issue is that flat white (Cortina White) is the only no-cost paint option. The rest will set out back $490 (for Tioman Green or the blue you see here) or $990 (for the rest). 

And then you can option the paint with a black roof, for $1380 combined with blue or green, or $1880 in all the other colours. The black exterior styling pack adds black highlights around the grille and on the front and rear bumpers. Those little Audi four-ring stickers on the rear doors are standard on this spec.

But to be honest, it stands out no matter what colour you choose, and that’s enough to get people’s heads turning on the street. And the interior design? Well, it has some good and bad points. See the interior pictures below to make up your own mind. 

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.

There are elements of the A1’s cabin design that are tremendous. And other bits that are not so tremendous. 

The bad bits include the fact you’re paying about $50,000 on the road for a car that has hard plastic just about everywhere the eye can see.

The good bits are that the textured plastics on the dash are beautiful, and so are the designed elements on the doors. I love the door handles, I love the metallic finish, I love the layout and I love the way it makes you forget that you’re in a luxury-branded car with hard plastic all around you.

The media screen and digital dashboard help, too - it feels technical and premium in the driver’s seat as a result. The graphics are crisp and clear, the menus are mostly easy to navigate, but I had some issues getting Apple CarPlay to work. It has wireless CarPlay, and I had it plugged in, so perhaps that was confusing things.

But the Audi media system also includes Audi Connect in this spec, meaning there are realtime map, traffic and hazard updates, plus a Wi-Fi hotspot, fuel prices, parking, weather and Google maps and services. It’s high-tech, and if that’s what you like, this is definitely going to please you more than a Mini Cooper.

Practicality is good, with bottle holders in all four doors, cup holders between the front seats and a covered centre console and wireless charging bay in front of the shifter. In the back, storage is sparse: aside from the door pockets, there’s nothing - no cup holders, no map pockets. 

There is enough space for four adults in the A1, so if you plan to take your mates to brunch or if you’ve got young kids, you should be comfortable enough in here.

I had the driver’s seat set for my own height (182cm) and I was able to slide in to the rear seat without much fuss at all, with adequate knee and toe room, and decent headroom too. Try and fit three across the back and it’ll be uncomfortable, unless those three are very slim. 

There are dual ISOFIX child-seat anchor points and three top-tether points, and the seat structure is pretty flat, making fitment of these types of seats simple enough.

The boot capacity is good for a car of this size at 335 litres, which is a solid 20 per cent bigger than before. You won’t find a spare under the boot floor, though, as all A1s have an inflator kit. The back seats fold down to allow 1090L of cargo capacity, but there’s a ledge you have to contend with if you’re trying to load larger items in. Maybe skip the IKEA trips in this one, then. 

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.

This 40 TFSI model is the big humdinger in the range. It has the donk, right?

Yeah, it’s a 2.0-litre four-cylinder turbo-petrol engine, which is a full litre bigger in capacity than the base model car. And it’s the same engine fitted to the Polo GTI - a proper hot hatch!

It doesn’t quite have double the power and torque of the entry-level 30 TFSI model, but it does have solid outputs of 147kW (at 4400-6000rpm) and 320Nm (from 1500-4400rpm). That’s enough to slingshot this A1 from 0-100km/h in a hot-hatch-rivalling 6.5 seconds, according to Audi.

Unlike the lower grades, it runs a six-speed dual-clutch automatic, which it needs because it has so much torque. The 30 and 35 TFSI variants have a seven-speeder. All of them, including this one, are front-wheel drive.

There is no quattro/all-wheel drive A1 this time around, and there won’t be an S1, either. So this is it if you want your kicks in a compact car from the Ingolstadt-based brand.  

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.

Claimed fuel consumption is rated at 6.4 litres per 100 kilometres. You might see close to that on a highway drive, but if you’re primarily city-dwelling like me, then expect higher.

I saw an average of 10.1L/100km during my urban review of the A1 40 TFSI. That was with stop-start engaged the whole time, and the occasional squeeze of the accelerator to test out the claimed acceleration.

Fuel tank size for the A1 is just 40 litres, so if you’re doing what I did with this grade of A1, you can expect to visit the servo every 400km or so.

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.

You shouldn’t be surprised to know that the A1 40 TFSI feels a lot like a Polo GTI to drive. It’s quick, it’s entertaining, it’s refined… it’s just about 50 per cent more expensive.

That mightn’t matter to you or factor into your considerations. I just want to point out that you can get a car that’s just as good to drive as this one, and still with a premium German brand attached to it, for a lot less.

The A1 does have it’s own spunk, though. It has a more masculine character, more aggressive styling, and more delightful interior design.

But it also has steering that is predictable and easy to judge, helping it feel nimble and grippy. From tight twisty roads to roundabouts, you’re going to be having fun in the A1 if you’re tooling around town. 

It feels planted and grippy - aside from some front-wheel spin during take-offs if the tyres are cold - and you might notice the suspension can be a touch noisy as it pitter-patters over inconsistencies in the road surface, but the ride is firm yet controlled, offering enough comfort over potholed city roads and speed humps for this tester. And there are several of each of those obstacles on my daily drive to work.

The engine is a sweetheart, offering brilliant linearity to its power delivery. It pulls hard from low in the rev range, meaning you’ll be able to zip through traffic without much hassle at all. The powertrain is super responsive to inputs at speed, especially if you put it in Dynamic mode, which also allows you to hear some pops and crackles from the exhaust system. 

That said, there is some vibration, shuddering and hesitation at low speeds, which is a combination of the stop-start system kicking in and out, a small amount of turbo-lag from the engine and some shuffling behind the scenes from the dual-clutch transmission. You might find the lurchy nature of the first-gear take-offs to be a bit hard to get used to, especially if you spend a lot of time in bumper-to-bumper traffic. 

While this is an Urban Guide review focused on city driving, I thoroughly recommend you find a quiet stretch of twisty road outside the city limits. You won't be disappointed.

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.

While the VW Polo GTI that this spec of A1 shares plenty with is backed by a five-year/unlimited kilometre warranty plan, the Audi-badged compact hatch still has a lesser three-year/unlimited kay cover. 

The A1 requires servicing every 12 months or 15,000km (just like a Polo), and there’s a pre-pay service pack you can roll into your finance if you so choose.

That service plan covers either three years/45,000km of driving ($1480) or five years/75,000km ($1990). In the case of the five-year plan, Audi is actually better value than the Polo GTI (which costs $2200 for pre-pay). 

Where is the Audi A1 built? You might be surprised to learn the answer is Spain.

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.
