The VW powertrain was pushing the limits of what can be done without urea fluid additive while meeting diesel emissions, and VW have now learned some things and are making adjustments to improve future designs.

Ford is probably learning some similar things it seems with gas EcoBoost & intercooling, and they will need to figure things out along the way too.
