Automobile produced by AudiAG. In its most recent iteration, introduced in the winter of 2003 as a 2004 model, the s4 is equipped w./ a 300+ bhp V8 engine, propelling this stealth car from 0-60 in near 5 seconds with quarter mile times estimated in the range of 13 seconds. An excellent automobile crafted with the German prowess which has come to be well associated with AudiAG. A classic in the making.
Jesus Christ - at first glance that looked like an A4, but then he fucking schooled that CLK55AMG. Wow. (I actually did this, ;) ... MB rates their models to quick ... their tranny programs are fucked up)
