That’s AS4 and S4 – just to avoid any misunderstandings… The AS4 is ABT’s tuning proposition for the all-new A4 that will go on sale in the States in early 2008. Our first reaction upon seeing the ABT prepped A4 was quite positive if you take out the fender gills that look totally out of place. The bodykit consists of front, side and rear skirts, a rear spoiler and a 4-pipe rear muffler while the AS4 also sits lower thanks to ABT’s sport suspension. Buyers can choose from two different types of alloy wheel styles (AR or BR) which are available in 18, 19 or 20-inch. -Continued after the jump

Altogether, four engines are available for the Abt AS4, starting with the base1.8 TSI upgraded from 160 HP to 200 HP. The 143HP 2.0 TDi (turbodiesel) engine is offered in two guises, with 170 and 200 HP while the 190 HP 2.7 TDi is tuned to deliver 230 HP. The 240 HP 3.0 TDI is also available with two power upgrades, with 270 HP (550 Nm torque) and 300 HP (600 Nm of torque).

For better braking power, the German tuner can also equip the AS4 with the Abt brake system (345 millimeter disc diameter) or the Abt sports brake system (diameter 380 millimeter).
