So if you are claiming the S85, a wonderful breathing machine, can only hit a (peak) VE of 60% that is absurdity. Even the "lowly" Z3 M Coupe can reach over 100% peak VE. Although I do not have the data handy, I am positive that the S85 (and thus S65) also reach over 100% peak VE. Comparing VE across FI and NA engines is pretty well meaningless just like comparing hp/l for FI vs. NA is.

I was thinking the same as most cars I check VE on generally do better than 90% or I be looking for an issue.
