hey i have been browsin here 4 a while and am wonderin what the diff is between audi b3 and the b4 thing is it all about is there a dif between specs..

 

b3 and b4 is the body style.. i dont know what years those stand for.. but i have a b5 s4.. it is a 2000 and i think it was still a b5 till 03?? maybe 04.. but the next body style was a b6.. and then b7 and so on

 

b3 was basically the a4 from 1988 to 1992 it had either a 10v I5 or my favorite a 20v I5, from 1993 to 1995 it was a slightly revised B4 model which was more aerodynamically pleasing, then came the B5 which was changed from audi 80/90 to audi a4 and later S4/ and RS4. that boddy style remained from 1995 (europe) to 2001 for the a4 and on til 2002 for the s4 variant.
