Audi A3 S Line buying guide
What is the Audi A3 S-Line?
The Audi A3 S-Line is the sportier version of the standard Audi A3 that gets you different exterior styling and great features as standard.
It's essentially a way to get all the sporty elements you need without forking out for the top-spec 'S' variant that's considerably more expensive.
The A3 S-Line has been around since its original launch back in 1996 and offered buyers a more affordable way into fast hatchback ownership.
– Read our Audi A3 review
What are the Audi A3 S-Line specs?
If your A3 has the S-Line kit, you get the same engines as the standard car, which includes two petrol engines and one larger diesel unit.
However, a plug-in hybrid (PHEV) variant also means you can drive up to 41 miles on electric power alone.
Regarding driving, it's a smooth experience but with a sporty edge – this balance is something Audi does very well.
This means it can be enjoyed by the average driver or by someone who considers themselves to be an enthusiast.
Fuel economy is good too, with the petrol returning up to 55.4mpg, the diesel returning 65.7mpg and the PHEV returning a claimed 46.3mpg.
Used Audi A3 S-Line features and equipment
What sets the A3 S-Line apart from the standard car is a real emphasis on sports styling, with more aggressive angles thanks to a body kit, larger wheels, sports suspension, LED headlights, dynamic indicators and rear privacy glass.
Aside from this, it's identical to a normal A3 and gets plush seats, a 10.1-inch infotainment display, Apple CarPlay and Android Auto connectivity, dual-zone climate control and USB charging ports.
Where the A3 S-Line sits in the Audi range
The Audi A3 S-Line is well-placed in the model range. It sits in the middle, above the Sport but below the Black Edition. It's the perfect middle ground for that sporty Audi aesthetic but without the added expense of the S3 or RS3 models – making insurance costs much higher.
The A3 S-Line closely rivals the Mercedes A-Class, BMW 1 Series and VW Golf.
