YES, the S65 is a lot like V tec engine, especially in the "flexible" powerband of the engine. when you are out of gear, the rpm of the engine will drop very fast.
Like all ferrari NA engines, like Porsche NA engines, V Tec engines and our M NA engines, the downfall of rpm is very fast with gear in/out.
This is especially true for NA engines, which are so "responsive" in this aspect than any turbo engines.
I know revs drop fast in these cars. But the M3 has a very linear powerband so not sure how one really drops out of it since there's no real cut off point. The problem with dropping into a low gear with VTEC (or vvtl-i) for that matter is literally having a drastic loss of power until those high cams kick in which is not really the same issue in the M3. That's the only point I was trying to make.
