The answer is... I don't know. But I can take an educated guess. The volume and margins calculations are likely different for Porsche and VW (lower volume, higher margins for Porsche). This might affect their projected spend/gain balances. They might also have _other_ projects in the pipeline that they would rather spend the resources on . Lose some income from existing lines but make it up with the others kind of deals. And the third possible alternative is they got caught with their pants down. They might not have taken this UNECE thing seriously and not made contingency plans and simply... Not have enough time to execute before they are not able to sell any more cars of that kind untill they fix it. If it's _that_ important for you, I can ask around at friends in the industry and let you know what I find out what is going on there. You can drop me an email at my contact I have in the profile.
