With 347 hp (255 kW) and 700 Nm torque as standard, the S4 TDI already makes a real statement.For even greater driving pleasure, you can now install our ABT Power performance upgrade, which utilises the high-tech control unit ABT Engine Control (AEC). CEO Hans-Jürgen Abt: "With 384 hp or 282 kW and a maximum torque of 760 Nm, the customer receives a significant increase in comparison to the standard model. This is also reflected in the acceleration figures. For the Avant, this means 0-100 km/h is reached in 4.7 rather than 4.9 seconds. Before the third generation A4, only the petrol RS could achieve that."The three litre V6 diesel engine of the S4 TDI provides plenty of thrust and is not slowed down by sharp bends. The optional ABT Coilover Suspension Springs facilitate variable all-round lowering from 15 mm to 40 mm. The ABT sports stabilizers reduce the rolling tendency and perfect the handling. Nevertheless, the driving comfort remains the same. The optional ABT coilover springs also ensure variable lowering from 15 to 40 mm. Lowering the S4 TDI also flatters its appearance by making it look more streamlined, sleeker and more sporty. Against this backdrop, ABT Sport GR 20-inch alloy wheels, as fitted to the pictured vehicle, come into full effect. Their combined matt black and diamond-machined finish make them a real eye-catcher.
