The rear spoiler is not only a sleek add-on part; it also provides an even better contact between car and asphalt. That is indeed necessary, as the Abt engineers have substantially increased the power of the state-of-the-art engines of the A4: equipped with Abt Power, the new 1.8 TFSI now delivers 200hp (147kW) instead of the serial 160hp (118kW). Equipped with Abt Power S, the engine even delivers 240hp (177kW) – thanks to the turbocharger developed by Abt replacing the serial charger.

Also the diesel engines are significantly more powerful. Equipped with Abt Power, the 2.0 turbo diesel delivers 170hp (125kW); with Abt Power S, the two-liter self-igniting engine has 200hp (147kW). Thanks to Abt Power, the 2.7 TDI delivers reliable 230hp (162 kW) instead of 190hp (140kW). The flagship diesel 3.0 TDI disposes of either 270hp/199kW (Abt Power) or of 300hp/221kW (Abt Power S) instead of 240hp (177kW). The Abt Power S version has an enormous torque of 600Nm.

The Abt suspension springs, and particularly the Abt adjustable sport suspension have been perfectly tuned to the character of the sporty sedan car by racing-pro Christian Abt. In order to adjust the brake force to the power potential of the Abt AS4, the Allgäu-based tuners offer either the Abt brake system (diameter: 345mm) or the Abt sport brake system (diameter: 380mm).

Elegant wheels from the Abt wheel program are ideal to complement the dynamic, exciting and powerful car. No matter whether sleek AR wheels or extravagant BR wheels – both suit the AS4 perfectly. AR and BR are both available in size 18, 19 or 20 inch, of course also together with suitable tires.
