ABT Audi AS4
From ABT press: Using premium manufactured body add-on parts, Abt Sportsline understands accentuating this skilful line management. Thus, a marked front grill and a matching front spoiler lip were developed for the Abt AS4 for an equally friendly and aggressive facial expression. This look continues to the Abt side skirts and the rear where the AS4 is equipped with a rear wing and rear skirt. Beside sportier optics the add-on parts also provide an improved contact pressure and so a more stable road holding.
The driver will appreciate this, as also concerning power, the engineers have done their job on the so-called "volume model" from Ingolstadt. Originally the 2.0 TDI engine performed 140 HP (103 kW) under the bonnet but after the power treatment in Kempten a total of 170 HP (125 kW) can be measured. The chip tuning perfected by Abt Sportsline which enables this leap, moreover causes a considerably improved responding behaviour of the power unit. Appropriate sound comes from the Abt rear muffler with four chrome end pipes and necessary safety from the Abt sport brake system.
The optimal contact to the road surface is an important fact when possessing so much power - Abt Sportsline has two important components: the Abt sport wheel SP1 in noble titanium design and a size of 8.5 x 19 inch as well as the matching tyres of Dunlop. The tyre manufacturer is not only partner of the champion team Audi Sport Team Abt Sportsline in the DTM, but also in the tuning business.
