For The best engine in the A1 for high-mileage cruising, with strong torque that helps it cope with long economy-minded gearing. The Audi A1 1.6 TDI S line brings touches of class not normally seen on a car this small.
Against There's some engine rattle when pulling away in town. Petrol-engined A1s are much more fun to drive. Suspension on the S line is a bit too firm and spoils the otherwise impressive ride.
The Audi A1 1.6 TDI S line is a mega-desirable supermini that lives up to everything the Audi brand stands for, but misses the fun of the 1.4-litre petrol model and adds extra cost.
The Audi A1 is a former What Car? Car of the Year winner, and it still holds our Supermini of the Year title. That's impressive, but even so there are some versions that are better than others in our view.
The best all-rounder is the 1.4 TFSI in Sport trim, because it’s enjoyable to drive and has decent fuel economy, but whichever A1 you pick, it will hold its value well and provide a decent amount of equipment.
SE trim is noticeably cheaper than the rest of the range, but you don’t forego too many of the toys that make the A1 feel a little more special than some of its rivals. If you go for SE, look at adding Bluetooth connection for an extra £300, but don’t get carried away with the lengthy options list.
S line specification brings more equipment, but also suspension that is too stiff for our liking. Sport is a good compromise between comfort and kit, so that’s the one we’d go for.
