Great timing with the motor show currently in my neighborhood...Taking into account the drop of the value of P. today (~20 % in line with VW), I would think that we need to be much more concerned about the reputational damage rather than with the type of engines to be used now and in future... Should this nightmare spread from the 4cyl. diesel engines to the 6cyl. engines and, further, from VW to Porsche...well, a liar is not to be believed even if he says the truth....
