As soon as I heard about the Audi V6 five years ago, I knew they would come out with a multi-valve version later (although I thought it would take 6 months - not six years). Anybody know why Audi didn't initially start the V6 program with a 24 valve version? Should us old 12valvers be thinking about exchanging the 12V for new 30Vs come time for the first major overhaul?
