I can think of one thing....the home market Dearborn didn't like the fact that the European designs were far superior and wanted to sabotage the products so designs for the North American market would come back here to the USA. This has been done many times over in the past,
from Capri, to Fiesta MKI (1970s), to Merkur XR4Ti and Scorpio, ect.....always take a solid basic product from Europe and have the home market folks add a ticking timebomb to sabotage that product.
Ford Germany cars have always been far superior to anything the domestic market company has offered and simply put Dearborn is jealous of this.
