It looks like Porsche has now properly finished the development process of the car. Looks like the engineers finally got through to the management while explaining that the car ist not ready yet in March 2013. I think a field test of this dimension was however never part of the planning angry they simply applied the banana maturity process - the product matures at home of the customers.

I am optimistic that they have now sorted out all the difficulties and everyone has their cars on the track the latest by the end of October.
