Audi S3 Review (2013-2020)

What is the Audi S3?

The third-generation Audi S3 is an upmarket high-performance compact car, and goes toe-to-toe with popular choices like the Volkswagen Golf R and BMW M140i.

Unlike some of its rivals however, the Audi is offered in a range of body styles; buyers can pick from a three-door hatch, a five-door hatch called the Sportback, a four-door Saloon and a Cabriolet. As a result, there’s something in the line-up to cater for most needs and desires. This array of options also means that the Audi can serve as an alternative to cars such as the Mercedes-Benz CLA and even the BMW 3 Series, widening its appeal.

The S3 was introduced into the UK in 2013, initially in three-door hatchback and five-door Sportback form, with the other body styles following later. It was powered by a turbocharged 2.0-litre four-cylinder engine that produced a stout 300hp, which was channelled to all four wheels via Audi’s quattro all-wheel-drive system. A choice of six-speed manual or six-speed S tronic dual-clutch automatic transmission was also offered, with the S tronic being the quickest and more efficient choice.

In 2021, this generation of the Audi S3 was replaced by a more angular successor, though some felt its design and quality – especially inside – was a step down on the third-generation model.

How practical is it?

Given it’s based on the Audi A3, a sensible family hatchback that majors on space and comfort, it’s no surprise that the S3 is pretty practical. At 325 litres, boot space is a little smaller than more mainstream family cars like the Volkswagen Golf, but better than premium performance rivals like the contemporary BMW M140i and Mercedes-Benz A45 AMG.

Meanwhile, up front there’s plenty of space for both occupants, while the back seats are also pretty roomy. Those rear seats fold down onto their bases and form a flush floor with the boot, too, so that you can slide larger, bulkier items of luggage into the S3 without a hitch.

The saloon version isn’t quite as practical as the hatchback simply by dint of the fact the boot opening is smaller, but it’s technically got a larger luggage compartment at 390 litres. There si, in short, plenty of room for a car of its type, and the same goes for the cabriolet; while obviously the rear seats are less spacious than either of its stablemates, it’s still a proper four-seater with a boot that can fit a weekly shop into it.

What's it like to drive?

Unsurprisingly, thanks to that turbocharged engine and all-wheel drive, the S3 is astoundingly quick off the line. Times for the benchmark 0-62mph sprint, regardless of version, are in the sub-five second range. And yet despite this sports car-like performance, the claimed average economy is around 40mpg.

On the road, the S3 feels stable and balanced. This, in conjunction with its traction-boosting all-wheel-drive system and powerful brakes, makes it easy to quickly traverse even more challenging roads. However, its steering isn’t particularly engaging or tactile – a classic Audi trait – which means the S3 ends up feeling not quite as exciting as some rivals.

But it’s not necessarily all about outright excitement and engagement, and many will appreciate the Audi’s blend of effortless high-speed performance and practicality. The hatch and saloon variants also both offer plenty of interior space and myriad storage areas, and even the convertible version serves up just enough space for four adults, while the sharp design and upmarket interior contribute further to its appeal.

Technology, equipment & infotainment

At its launch, the S3 was the flagship model in the A3 line and, as you’d hope, it was well equipped; standard equipment included cruise control, dual-zone climate control, sports suspension and adaptive steering. Other upgrades included a host of S3-specific features, such as 18-inch anthracite wheels, black brake calipers, bespoke instruments, a subtle styling kit and heated Nappa leather-covered sports seats.

The S3 was offered with technology often found in larger cars, such as all-LED headlights and adaptive cruise control, meaning premium car buyers could downsize into something smaller and lighter without sacrificing the creature comforts they’d become accustomed to. A facelift would follow in 2016, which served to modernise the looks and equipment of the S3 while also boosting its performance slightly.

Audi S3 running costs

One of the reasons that the Audi S3 is a popular option is because, like the Volkswagen Golf R, it offers remarkable performance without crippling running costs.

When it was unveiled, for example, the S Tronic version was reputed to average 40mpg and emit 159g/km of CO2, which was on a par with many a conventional petrol hatchback. That said, although the S Tronic version was the most efficient in the range, any savings were negligible; the Vehicle Excise Duty costs were the same and there was only a very slight difference in company car tax costs and fuel consumption.

The real-world fuel consumption figures were unsurprisingly a little lower than the official lab-tested figures, but even so, most S3s will easily average around 30mpg, if not slightly more. This means that you can expect to travel upwards of 350 miles on a single tank, which isn’t bad for a high-performance compact car.

Desirability further helped to prop up the S3’s depreciation figures, so owners wouldn’t lose money hand over fist. Every S3 also came with a three-year warranty, which was unlimited with regards to mileage in the first two years but capped to a total of 60,000 miles in the third year. A three-year paint warranty, and a 12-year anti-corrosion warranty, was also included.

Fortunately, if ongoing reliability and costs are a concern, Audi offers Approved Used cars. These include a minimum of 12 months’ warranty, as well as roadside assistance, and are all comprehensively checked before sale. Cars up to eight years old are available, so there is typically a range of Audi S3s, Sportbacks, Saloons and Cabriolets available.

Servicing costs were admittedly higher compared with some rival offerings when new but, these days, a decent Volkswagen Audi Group specialist should be able to maintain an S3 for sensible money.

Audi S3 reliability

Audi generally has a reputation for high-quality cars but it often doesn’t fare particularly well in the reliability stakes. Trawl through the annual reliability and brand surveys and you’ll often find it in a middling or disappointingly low position.

Some of those poor results can be attributed to the fact that Audi's cars are often more complex and customers are often justifiably more demanding; someone buying an inexpensive hatch might overlook or ignore a small fault, whereas someone paying a premium would understandably expect it to be perfect – resulting in repeated dealer visits and dissatisfaction.

That said, the Audi A3 on which the S3 is based is generally held in high regard for reliability and quality. Major problems with the S3 also tend to be uncommon. It’s important that servicing is carried out on time and as per the schedule however, to avoid any problems in the long run or when the time comes to sell the car. Consequently, if you’re looking at a used example, make sure that its service history is complete and up to date.

Don’t worry if the service stamps are from an independent specialist; S3s are often owned by enthusiasts who will have sought out specialists capable of maintaining and repairing the car to the highest standard. If you’re not sure about the company in question, carry out a quick internet search, as the first few reviews and reports will often tell you all you need to know.
