Hi Yuly...
Well the move from 330i to 335i signals an engine change from the 3.0l NA N52 I-6 to the new 3.0l twin-turbo N54 I-6 engine. the '35' in 335 implies the engine has the performance of a 3.5l courtesy FI eventhough it remains a 3.0l. Well that still doesn't explain why a 325i is 3.0l and why the new '07 328i is still the same 3.0l. I think that's just pure marketing crap
