Visual upgrades include carbon fibre vents on the wings just behind the front wheels, carbon fibre side skirts, carbon fibre diffuser with centrally mounted twin exhaust tips and 18-inch ABT split-rim alloys.
The result looks very good and gives the 5-door A1 a much sportier look.
Under the bonnet, the 1.4 litre TFSI engine gets a good boost in power. The 122bhp variant now has 160bhp and the 185bhp variant has its power increased to 210bhp.
ABT also offers a small power boost on the 1.2 litre petrol and 1.6 litre TDi engines.
