If you don't mind me asking, what was your production date? My salesman advised me that driveshafts started being used all the way back in September.

As I thought this was done for something to do with emissions so that the diameter of the prop was narrower with the steel as it’s stronger than carbon. To house something for the emissions
Could be a load off crap, but that’s just what I recall reading

I read something similar. Supposedly the new particulate filter is what drove the switch to steel, because a narrower driveshaft was needed to clear the exhaust. I can't say whether or not my car will have the particulate filter (but I'm guessing it won't), since the change was meant for only EU-version cars. Mine is American spec and should have the normal exhaust. Carbon driveshafts are known for being stronger (and lighter) than equivalent steel.

Delivery is a week away, so I'll find out a lot very soon.
