I was wondering which models had the I5 20v vs. the V6 engines in the 90s. I know the 20v was introduced in 91 and they used it in the 200 quattro, also the S4/S6 was using it ...untill when? How about the 92 on model year? Were those V6? When did they swith over to the V6 for the S models? Thanks, Zsolt
