It's a bit hyperbolic, it's only the TDI engines that got dropped for Ford engines, as the TDI engines couldn't pass Euro6 without more engineering work than buying Ford's engines cost.
Shame though, since those Ford diesels are woeful and despite the NOx emissions, the TDI's were really good.
The fines don't make sense to me. If the cars are supposed to meet some specific standard but don't a fine will make it a business problem to hey to pass the cost of the fine along to the consumer. Consider the pickup trucks in the US: typically worse emissions per passenger compared to a "commuter vehicle".
If something doesn't pass regulation, why should it be allowed to be sold at all?
