Hi guys,
im thinking about getting the new turbo engine that is available in the 3 series, my question aside from the increase in power from an inline 6: what are the advantages and disadvantages as far as maintenance and life of the two engines are concerned.

possible disadvantages over naturally aspirated inline-6
- fuel consumption and C02 output is higher
- it is more expensive to buy
- turbos fail and they can be expensive to replace (it's hard to know at this stage how reliable the N54 engine turbos will be)
- the turbo engine might be more prone to overheating (some E92 drivers have reported problems)
- the engine is slightly heavier (a tiny impact on handling)
- some people have said it doesn't sound as nice at idle (probably lean burn ... diesel like clatter)
- there is some turbo lag (although it is tiny). Some people hate this.

A big pro is that the max torgue (400 Nm) that is availble from almost idling (1300 rpm).

I have not heard about any turbo lag, thanks to the two small turbos.

The question is how much or more importantly... is it noticeable.
In the case of the 335i, every review I have read has said the turbo lag was so small it was not noticeable.

It's a turbo, so by design there is lag.
