actually, the TDI that VW and Audi use are able to compete with petrol engines of the same class, the TDI R10 for example http://en.wikipedia.org/wiki/Audi_R10
i think that's because the rule that limits the hp tends to favor diesels that makes massive torque at the same hp as petrols. anyways, would be interesting to drive.
A boost gauge is not a functional part of a exhaust driven forced induction system, I was just curious.
As the quick model is a turbo charged power-plant, as to whether it had the same slightly out-dated modeling that gives the current turbo cars such a lengthy spool time.
edit:
Ok so studying it a bit further, the 1.4 160hp is twin charged, the 2.0 200hp version is just turbocharged. My question still stands, has the boost model changed?
